Field of the invention The invention relates to an apparatus for separating solid food matter from a received mixture comprising water and solid food matter, a kit of parts for the assembly of an apparatus for separating solid food matter from a received mixture comprising water and solid food matter, and a method of separating solid food matter from a received mixture comprising water and solid food matter. Background to the invention Food processing apparatuses typically generate waste which has to be disposed of. For example, potato peelers output a mixture comprising water, potato peel, starch and various water contaminants such as soil. Regulatory authorities in many jurisdictions now impose restrictions on the disposal of food waste products (such as solid food matter or solid vegetable matter and, particularly, starch) into the public drainage system, since the waste (particularly starch) can cause blockages in drains and sewers. Several food waste products, including starch, can also be recycled if recovered and are used to produce, for example, animal feed, food thickeners and adhesives. It is therefore beneficial, and in some cases mandatory, to install systems capable of recovering solid food matter from the output of food processing apparatuses. The disposal of a starch and water mixture is particularly problematic. Starch to be disposed of as a solid must be dewatered to minimise weight; similarly, water must be cleared of starch before it may be disposed of safely down a drain. Starch and water can be separated using centrifugal filtration. Centrifugal filters, however, are often prohibitively expensive, particularly for smaller producers of food products such as fast food retailers. Moreover, the use of a centrifugal filter typically requires prior maceration of larger pieces of solid food matter. It would therefore be beneficial to have a more cost-effective way of disposing of waste comprising mixtures of solid food matter and water from food processing apparatuses. Summary of the invention A first aspect of the invention provides apparatus for separating solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) from a received mixture comprising (liquid) water and solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch), the apparatus comprising a filtering mesh and one or more fluid (typically liquid) sources, the filtering mesh being configured to allow passage of water therethrough and to inhibit passage of at least some of the solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) therethrough, and the one or more fluid (liquid) sources being configured to direct fluid onto the received mixture comprising (liquid) water and solid food matter (so as to separate at least some of the solid food matter from the received mixture comprising water and solid food matter) and/or onto a mixture comprising (liquid) water and solid food matter which has passed through the filtering mesh (so as to separate at least some of the solid food matter from said mixture comprising water and solid food matter which has passed through the filtering mesh). Typically, the received mixture comprising water and solid food matter is a flowing or flowable mixture. Additionally or alternatively, it may be that the mixture comprising water and solid food matter which has passed through the filtering mesh is a flowing or flowable mixture. The received mixture comprising water and solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) may comprise an output from a food processing apparatus (for example a vegetable processing apparatus such as a vegetable peeler, such as a potato peeler or other root vegetable peeler). The water in the received mixture comprising water and solid food matter may be provided as part of a solution, which may for example comprise one or more food processing substances such as de-foaming agents or other dissolved chemical substances. The filtering mesh typically comprises a plurality of openings. The openings are typically sized to permit flow of water therethrough but to inhibit flow of the solid food matter therethrough. Typically, the openings of the filtering mesh each have a flow area through which water can flow. Typically the openings of the filtering mesh have equal (or substantially equal) flow areas (if the openings of the filtering mesh are of variable size, the openings of the filtering mesh typically have equal (or substantially equal) flow areas at least when the filtering mesh is in a relaxed state). By "substantially equal", we include the possibility that the openings of the filtering mesh each have flow areas within 100% (typically within 50%, more typically within 20%) of a mean flow area of the openings of the filtering mesh. It will be understood that the openings of the filtering mesh are sized to inhibit particles of solid food matter having a size greater than a threshold size from passing therethrough. The openings of the filtering mesh are also thus sized to permit particles of solid food matter having a size less than a threshold size to pass therethrough. For example, the openings of the filtering mesh may be sized to inhibit particles of solid food matter having a largest dimension (e.g. length, height or diameter) greater than the smallest dimension (e.g. length or diameter) of the flow areas of the openings (or at least of the flow areas of a majority of the openings) of the filtering mesh from passing therethrough and to permit (for example) particles having a largest dimension (e.g. length, height or diameter) less than the smallest dimension (e.g. length or diameter) of the flow areas of the openings (or at least of the flow areas of a majority of the openings) to pass therethrough. It will be understood that, the greater the flow area of the openings of the filtering mesh, the more solid food matter can flow through the openings of the filtering mesh. However, the smaller the flow area of the openings, the greater the likelihood that the openings will become clogged with solid food matter over time (reducing the quantity of water that can flow through the openings per unit time). Typically the flow area of each opening (or at least of each of a majority of the openings) of the filtering mesh has a largest dimension (e.g. length or diameter) of between 0.5 mm and 10 mm, or between 0.5 mm and 5 mm, or between 0.5 mm and 3 mm, or between 0.5 mm and 1.5 mm. It may be that the filtering mesh comprises a mesh made up of two or more layers. Typically, the filtering mesh comprises a net. Typically the net of the filtering mesh is configured to receive the received mixture comprising water and solid food matter, to retain at least some of the solid food matter, and to allow water to pass therethrough. Typically the net of the filtering mesh is provided in the form of a bag. Typically, the net of the filtering mesh comprises an inlet configured to receive the received mixture comprising water and solid food matter. Typically the net of the filtering mesh comprises the said plurality of openings of the filtering mesh. In this case, the openings are typically sized to retain at least some of the solid food matter (typically pieces of solid food matter having a size greater than a threshold size - see above) in the said net, and to allow passage of at least some of the water (and typically pieces of solid food matter having a size less than a threshold size - see above) through the openings. Typically, the said net of the filtering mesh is made of a resilient material (such as a plastics material). Typically the net of the filtering mesh is expandable. Typically, the filtering mesh is expandable in volume by at least 50%, at least 60%, at least 70%, at least 80%, at least 90% or at least 100% of its relaxed volume. Typically the one or more fluid sources are configured to direct fluid (typically liquid) onto the received mixture comprising water and solid food matter by directing fluid at the filtering mesh. In this case the fluid is typically directed onto the mixture comprising water and solid food matter through the openings of the filtering mesh. The water in the mixture comprising water and solid food matter which has passed through the filtering mesh may be provided as part of a solution, which may for example comprise one or more food processing substances such as de-foaming agents or other dissolved chemical substances. It will be understood that the term "fluid source" is not intended to be limited to an original source of fluid (such as mains water). Rather, the term "fluid source" includes an intermediate source (such as a spray nozzle), even if the fluid from the intermediate source is itself obtained from an original source. Typically the one or more fluid sources comprise two or more fluid sources configured to direct fluid onto the received mixture comprising water and solid food matter. Typically, there is some overlap as to where two or more of the said fluid sources direct fluid (e.g. the said two or more fluid sources may each direct fluid onto a central portion of the filtering mesh). Typically the one or more fluid sources comprise two or more fluid sources configured to direct fluid onto the mixture comprising water and solid food matter which has passed through the filtering mesh. Typically, there is some overlap as to where two or more of the said fluid sources direct fluid. Typically the one or more fluid sources comprise at least one fluid source configured to direct fluid onto the received mixture comprising water and solid food matter and at least one fluid source configured to direct fluid onto the mixture comprising water and solid food matter which has passed through the filtering mesh. Typically, the one or more fluid sources comprise one or more (typically two or more, and in a particular embodiment four) fluid (liquid) sprays or fluid (liquid) spray nozzles. Each of the said one or more fluid sprays or fluid spray nozzles is typically configured to direct fluid in a predominantly two-dimensional fan over an angle of between 20° and 55°, or between 25° and 50°, or between 30° and 45° (e.g. 33°). For example, the one or more spray nozzles may comprise one or more VeeJet ^® spray nozzles. It may be that the one or more spray nozzles are configured to receive water from an original source of water, such as the water mains. The apparatus may comprise a main container. Typically, the main container comprises a lid. Typically, the main container houses the filtering mesh. Typically, the lid has a closed position in which it covers the filtering mesh. Typically, the lid has an internal surface facing the filtering mesh when the lid is in the closed position. Typically, the lid has an open position in which the filtering mesh is accessible (so that it can be removed from the main container for cleaning or replacement). It may be that the lid is hingedly mounted to the main container. Alternatively, it may be that the lid is not hingedly mounted to the main container. The one or more fluid sources are typically mounted on (carried by) the said internal surface of the lid. Typically the one or more fluid sources are configured to direct fluid towards (typically at) the filtering mesh when the lid is in the closed position. Typically the one or more fluid sources (and typically two or more of the said fluid sources) are configured to direct fluid towards (typically at) a central portion of the filtering mesh when the lid is in the closed position. The main container may comprise one or more (typically removable) interior chambers. For example, the main container may further comprise a first (typically removable) interior chamber. The main container may further comprise a second (typically removable) interior chamber. Typically, the second (typically removable) interior chamber is provided downstream of the first (typically removable) interior chamber. The first and second (typically removable) interior chambers may be configured such that they are in fluid communication with one another. The first (typically removable) interior chamber may comprise one or more at least partially perforated or honeycombed walls. The second (typically removable) interior chamber may comprise one or more at least partially perforated or honeycombed walls. Fluid may be permitted to flow from the first (typically removable) interior chamber to the second (typically removable) interior chamber by passing through at least partially perforated or honeycombed walls of the first and second (typically removable) interior chambers (e.g. a downstream wall of the first interior chamber and an upstream wall of the second interior chamber). In some embodiments, the filtering mesh is provided inside (i.e. the filtering mesh may be housed by) the first (typically removable) interior chamber. The net of the filtering mesh (where provided) typically comprises an inlet secured to (and in communication with) an inlet of the first (typically removable) interior chamber and/or an inlet of the main container by way of a fast-release connection. The fast release connection enables the filtering mesh to be easily removed for cleaning or replacement. In use, the fluid directed by the one or more fluid sources typically directs solid food matter or a (e.g. foamed) mixture comprising solid food matter and water out of and away from openings of the filtering mesh, thereby allowing more water and solid food matter to pass therethrough. The fluid directed by the one or more fluid sources also typically reduces foaming of the mixture comprising solid food matter and water which has passed through the filtering mesh. Surprisingly, the fluid directed by the one or more fluid sources removes some solid food matter from the received mixture comprising water and solid food matter and/or from the mixture comprising solid food matter and water which has passed through the filtering mesh by directing or carrying solid food matter out of the said mixture, typically towards an internal surface (for example, a base) of the apparatus (such as an internal surface, such as a base, of the first (typically removable) interior chamber or an internal surface, such as a base, of the main container) where it can aggregate (see below). The fluid directed by the one or more fluid sources also typically compacts the aggregated solid food matter on the said internal surface (for example, a base) of the apparatus (such as an internal surface, such as a base, of the first (typically removable) interior chamber or an internal surface, such as a base, of the main container). The apparatus may further comprise a supporting mesh configured to (mechanically) support the filtering mesh and/or to reduce foaming of a mixture comprising water and solid food matter which has passed through the filtering mesh. Preferably, the supporting mesh is adjacent to and downstream of the filtering mesh. Typically, the supporting mesh is housed in the first (typically removable) interior chamber. In some embodiments, the supporting mesh comprises a plurality of openings. Typically, the openings of the supporting mesh are sized to allow passage of water (and typically pieces of solid food matter having a size less than a threshold size - see above) therethrough but to inhibit flow of solid food matter (typically pieces of solid food matter having a size greater than a threshold size - see above) therethrough. Typically, the openings of the supporting mesh each have a flow area through which water (or small pieces of solid food matter) can flow. Typically the openings of the supporting mesh have equal (or substantially equal) flow areas (if the openings of the supporting mesh are of variable size, the openings of the supporting mesh typically have equal (or substantially equal) flow areas at least when the filtering mesh is in a relaxed state). By "substantially equal", we include the possibility that the openings of the filtering mesh each have flow areas within 100% (typically to within 50%, more typically to within 20%) of a mean flow area of the openings of the supporting mesh. It will be understood that, the greater the flow area of the openings, the more solid food matter can flow through the supporting mesh. However, the smaller the flow area of the openings, the greater the likelihood that the openings will become clogged with solid food matter over time. Typically the flow area of each opening (or at least of each of a majority of the openings) of the supporting mesh has a maximum dimension of between 0.5 mm and 10 mm, or between 0.5 mm and 5 mm, or between 0.5 mm and 3 mm, or between 0.5 mm and 1.5 mm. Typically, the supporting mesh comprises a net. Typically the net of the supporting mesh is provided around (at least part of, typically at least the majority of, typically all of apart from around the inlet of) the filtering mesh (which is typically also a net as discussed above). Typically the net of the supporting mesh is provided in the form of a bag. The filtering mesh (which may also comprise a net in the form of a bag) may be provided inside the bag of the supporting mesh. Typically, the net of the supporting mesh comprises an inlet configured to receive the received mixture comprising water and solid food matter and/or the inlet of the filtering mesh (said inlet of the filtering mesh may be configured to receive the received mixture comprising water and solid food matter). The inlet of the net of the supporting mesh is typically secured to an inlet of the first interior chamber and/or an inlet of the main container and/or the inlet of the filtering mesh by way of a fast release connection. Typically the net of the supporting mesh comprises the said plurality of openings of the supporting mesh. In this case, the openings are typically sized to retain (typically some but not all of the) solid food matter in the said net of the supporting mesh, and to allow passage of at least some of the water (and typically some but not all of the solid food matter) through the openings. Typically, the said net of the supporting mesh is made of a resilient material (such as a plastics material). Typically the net of the supporting mesh is expandable. Typically, the supporting mesh (when provided) is expandable in volume by at least 50%, at least 60%, at least 70%, at least 80%, at least 90% or at least 100% of its relaxed volume. It will be understood that the openings of the supporting mesh are sized to permit particles of solid food matter having a size less than a threshold size to pass therethrough and to inhibit particles of solid food matter having a size greater than a threshold size from passing therethrough. For example, the openings of the supporting mesh may be sized to permit particles having a largest dimension (e.g. length, height or diameter) of less than the smallest dimension (e.g. length or diameter) of the flow areas of the openings (or at least of the flow areas of a majority of the openings) of the supporting mesh to pass therethrough and to inhibit particles of solid food matter having a largest dimension (e.g. length, height or diameter) greater than the smallest dimension (e.g. length or diameter) of the flow areas of the openings (or at least of the flow areas of a majority of the openings) of the supporting mesh from passing therethrough. The supporting mesh typically suppresses a surge of solid food matter and water passing through the filtering mesh which can occur when the apparatus is in use. Without the said supporting mesh, said surge of solid food matter and water can be difficult to control. It may be that the supporting mesh comprises a mesh made up of two or more layers. Typically the one or more fluid sources are configured to direct fluid onto the received mixture comprising water and solid food matter by directing fluid towards (typically at) the supporting mesh (and the fluid is directed onto the received mixture comprising water and solid food matter through openings in the supporting mesh and typically through the openings in the said filtering mesh). Typically the one or more fluid sources (and typically two or more of the said fluid sources) are configured to direct fluid onto a central portion of the supporting mesh. Typically the fluid directed by the one or more fluid sources causes at least some of the solid food matter in the mixture comprising solid food matter and water which has passed through the filtering mesh (and/or the supporting mesh, when the supporting mesh is provided) to move towards and aggregate upon an or the internal surface of the apparatus (such as an internal surface (for example, a base) of the first (typically removable) interior chamber and/or an internal surface (for example, a base) of the main container). Typically the fluid directed by the one or more fluid sources causes at least some of the solid food matter from the received mixture comprising water and solid food matter to pass through the filtering mesh (and/or the supporting mesh, when the supporting mesh is provided) and to move towards and aggregate upon an or the internal surface (such as a base) of the apparatus (such as an internal surface (for example, a base) of the first (typically removable) interior chamber and/or an internal surface (for example, a base) of the main container). Typically the apparatus (typically the container, more typically the first interior chamber of the container) comprises a solid food matter collecting vessel. Typically the internal surface of the apparatus onto which fluid directed by the fluid sources causes solid food matter to aggregate comprises an internal surface (e.g. a base) of the solid food matter collecting vessel. More generally, typically the apparatus further comprises a solid food matter collecting vessel and the one or more fluid sources are configured to direct fluid onto the received mixture comprising water and solid food matter and/or onto a or the mixture comprising water and solid food matter which has passed through the filtering mesh to cause at least some of the solid food matter to aggregate within the solid food matter collecting vessel. The solid food matter collecting vessel is typically configured to provide a partial barrier to a flow of collected solid food matter. Where the solid food matter collecting vessel is provided in the first interior chamber of the container of the apparatus, the solid food matter collecting vessel is typically configured to provide a partial barrier to a flow of collected solid food matter out of the first (typically removable) interior chamber (e.g. through one or more perforated or honeycombed walls thereof). It may be that the first (typically removable) interior chamber comprises a base which does not permit the flow of solid food matter or water therethrough (e.g. the base may be non-perforated). In this case, the solid food matter collecting vessel may be formed by fixing one or more strips of material (which do not permit the flow of solid food matter or water therethrough) to one or more (perforated) side walls of the first interior chamber, typically adjacent the base, to cover a portion (e.g. at least 1 %, at least 2%, at least 5% or at least 10%) of the perforations on the said side wall(s). In this case, the solid food matter collecting vessel is typically configured to collect solid food matter between the said strips of material and the base. The said strips of material typically extend along (e.g. at least 70% of, preferably at least 90% of, typically the entirety of) the length of the walls to which they are fixed. The said strips of material typically have heights which are less than 20% (more typically less than 10%, in some embodiments less than 5%) of the heights of the walls to which they are fixed. The said strips of material typically together define an opening through which solid food matter can be collected in the solid food matter collecting vessel. In other embodiments, the solid food matter collecting vessel may be formed by fitting a (typically removable) tray insert to the base of the first interior chamber (or within the first interior chamber and/or on the base of the main container). The said tray insert typically comprises a base (which does not permit the flow of solid food matter or water therethrough) and one or more (typically two or more or three or more, in a particular embodiment four) walls extending therefrom (typically from the edges thereof) to define an opening through which solid food matter can be collected. The said walls are typically configured so as to inhibit the flow of solid food matter or water therethrough. Typically the tray is inserted into the first container with an interference fit such that the walls of the tray insert are in contact with corresponding walls of the first container. Typically the walls have heights which are less than 20% (more typically less than 10%, in some embodiments less than 5%) of the height of the corresponding (perforated) walls of the first interior chamber with which they are adjacent and/or in contact. In some embodiments, a second solid food matter collecting vessel is provided in the second (typically removable) interior chamber. The second solid food matter collecting vessel typically has a similar structure and properties as the solid food matter collecting vessel provided in the first (typically removable) interior chamber. It may be that the fluid directed by the one or more fluid sources is or comprises a liquid. Typically the fluid directed by the one or more fluid sources comprises (liquid) water. It may be that the fluid directed by the one or more fluid sources is at least predominantly (liquid) water. It may be that (liquid) water which is directed by the one or more fluid sources is provided as part of a solution, which may for example comprise one or more food processing substances such as de-foaming agents or other dissolved chemical substances. A mixture comprising solid food matter and water is typically permitted to flow from the first (typically removable) interior chamber into the second (typically removable) interior chamber through at least partially perforated or honeycombed walls of the first and second (typically removable) interior chambers (typically passing through a void provided between the first and second interior chambers). Typically, the lid of the container comprises a handle configured to permit opening and closing of the lid. The handle is typically coupled to a mechanism which, when the handle is used to open the lid (and/or to unlock the lid), prevents flow of fluid from the one or more fluid sources (when the lid is in an open position), and when the handle is used to close the lid (and/or to lock the lid in a closed position), permits flow of fluid from the one or more fluid sources (when the lid is in a closed position). The said mechanism typically comprises a tap having an open position in which fluid is permitted to flow from the one or more fluid sources (when the lid is in a closed position) and a closed position in which fluid is prevented from flowing from the one or more fluid sources (when the lid is in an open position). As explained above, it may be that the filtering mesh (and, where provided, the supporting mesh) permits the flow of particles of solid food matter having a size which is less than a threshold size therethrough. The apparatus may further comprise a solid food matter blocking filter downstream of the filtering mesh (and, when provided, the supporting mesh). The solid food matter blocking filter is also typically provided downstream of where the fluid sources are directed onto the received mixture comprising (liquid) water and solid food matter and/or onto a mixture comprising (liquid) water and solid food matter which has passed through the filtering mesh. Typically, the first interior chamber comprises the filtering mesh and the second interior chamber comprises the solid food matter blocking filter. The solid food matter blocking filter is typically configured to receive a flow comprising a mixture comprising water and solid food matter which has passed through the filtering mesh (and, where provided, the supporting mesh). The solid food matter blocking filter is typically configured to inhibit the flow of solid food matter therethrough and to allow passage of water therethrough. It will be understood that, ideally, the solid food matter blocking filter blocks 100% of the solid food matter incident thereon from passing through it. However, in practice, it is sufficient for the solid food matter blocking filter to block less than 100% of the solid food matter incident thereon (e.g. the solid food matter blocking filter may block at least 50% of the solid food matter incident thereon, more preferably at least 70% of the solid food matter incident thereon, even more preferably at least 80% of the solid food matter incident thereon), particularly as the fluid directed by the fluid sources removes a portion of the solid food matter which has passed through the filtering mesh before it reaches the solid food matter blocking filter. The solid food matter blocking filter may comprise a mesh. The mesh of the solid food matter blocking filter typically comprises a plurality of openings sized to permit flow of water therethrough and to inhibit flow of solid food matter (including particles of solid food matter having a size less than the said threshold size - see above) therethrough. Typically, the openings of the solid food matter blocking filter mesh are smaller than the openings of the filtering mesh (and smaller than the openings of the supporting mesh, where provided). Typically, the openings of solid food matter blocking filter mesh each have a flow area through which water can flow through from an upstream side to a downstream side of the solid food matter blocking filter. Typically the openings of the solid food matter blocking filter mesh have equal (or substantially equal) flow areas. By "substantially equal", we include the possibility that the openings of the solid food matter blocking filter mesh each have flow areas within 100% (typically to within 50%, more typically to within 20%) of a mean flow area of the openings of the solid food matter blocking filter mesh. It will be understood that, the greater the flow area of the openings of the solid food matter blocking filter mesh, the more solid food matter can flow through the filtering mesh. However, the smaller the flow area of the openings, the greater the likelihood that the openings will become clogged with solid food matter over time. Typically the flow area of each opening (or at least of each of a majority of the openings) of the solid food matter blocking filter mesh has a largest dimension (e.g. length or diameter) of between 50 μιη and 350 μιη, or between 70 μιη and 250 μιη, or between 90 μιη and 120 μιη. Typically the flow area of the opening having the greatest flow area (or at least of each of a majority of the openings) of the solid food matter blocking filter mesh has a largest dimension (e.g. length or diameter) which is less than the smallest dimension (e.g. length or diameter) of the flow area of the opening having the smallest flow area of the filtering mesh. It may be that the solid food matter blocking filter comprises a mesh made up of two or more layers. It may be that the solid food matter blocking filter extends between opposing walls of the main container predominantly in a plane perpendicular to a principle direction of flow of the mixture comprising water and solid food matter output from the filtering mesh (and, where provided, the supporting mesh). More typically, the solid food matter blocking filter extends across a (e.g. external) surface of at least one wall of the second (typically removable) interior chamber (e.g. a surface of a wall of the second interior chamber adjacent to and facing the first interior chamber). Typically the said at least one wall comprises a (typically perforated) wall of the second interior chamber through which the first (typically removable) interior chamber is in fluid communication. Typically, the solid food matter blocking filter extends between opposing walls of said second (typically removable) interior chamber. The solid food matter blocking filter typically extends predominantly in a plane perpendicular to a principle direction of flow of the mixture comprising water and solid food matter output from the filtering mesh (and, where provided, from the supporting mesh) towards the second interior chamber. The solid food matter blocking filter typically comprises a mesh covering at least a portion (preferably greater than 50% of an upstream surface area, more preferably greater than 75% of an upstream surface area, preferably all) of the said (typically perforated) wall of the second (typically removable) interior chamber of the apparatus. Typically the said wall of the second interior chamber extends predominantly in a plane perpendicular to a principle direction of flow of the mixture comprising water and solid food matter output from the filtering mesh. Typically, edges of the solid food matter blocking filter are sealed to the second (typically removable) interior chamber by a (for example, silicone) seal. It will be understood that the solid food matter blocking filter may cover more than one wall of the second interior chamber. For example, the second interior chamber may comprise two or more (or three or more) perforated walls and it may be that the solid food matter blocking filter covers at least a portion (preferably greater than 50% of an upstream surface area, more preferably greater than 75% of an upstream surface area, preferably all) of each of the said perforated walls. In some embodiments, the solid food matter blocking filter comprises a metallic (for example, stainless steel) mesh. Typically, the apparatus further comprises one or more clearing fluid sources configured to direct fluid (typically liquid) onto the solid food matter blocking filter. The one or more clearing sources may be configured to direct fluid onto the solid food matter blocking filter (typically a side of the solid food matter blocking filter which extends predominantly in a plane perpendicular to a principle direction of flow of the mixture comprising water and solid food matter output from the filtering mesh). The one or more clearing fluid sources may be configured to direct fluid onto an upstream side of the solid food matter blocking filter. The one or more clearing fluid sources are typically configured to remove at least some of the solid food matter from the upstream side of the solid food matter blocking filter in use. The one or more clearing fluid sources are typically configured to direct fluid onto the solid food matter blocking filter so as to unblock the solid food matter blocking filter of solid food matter. The one or more clearing fluid sources may be configured to cause solid food matter removed from the solid food matter blocking filter to move towards and aggregate upon an or the internal surface of the apparatus. The internal surface of the apparatus onto which solid food matter is directed by the one or more clearing fluid sources could be the same or (more typically) a different internal surface of the apparatus as the internal surface of the apparatus onto which solid food matter is directed by the one or more fluid sources. It may be that the internal surface of the apparatus onto which solid food matter is directed by the one or more clearing fluid sources is an internal surface (such as a base) of the main container. The said internal surface may be an internal surface of the solid food matter collecting vessel or of a further solid food matter collecting vessel. Typically, the fluid directed by the one or more clearing fluid sources comprises liquid. Typically the fluid directed by the one or more clearing fluid sources comprises (liquid) water. Typically the fluid directed by the one or more clearing fluid sources is at least predominantly liquid water. It may be that the water directed by the one or more clearing fluid sources is provided as part of a solution, for example comprising one or more food processing substances such as de-foaming agents or other dissolved chemical substances. The clearing fluid sources are typically mounted to an internal surface of the lid of the main container. The clearing fluid sources are typically mounted on the internal surface of the lid at a position which, when the lid is closed, is provided directly above (i.e. at a position occupying an imaginary volume extending upwards from the boundaries of) a void extending between the first and second interior chambers. The clearing fluid sources are typically positioned downstream of the fluid sources. The clearing fluid sources typically comprise one or more (in a particular embodiment, two) fluid sprays or fluid spray nozzles. Each of the said one or more fluid sprays or fluid spray nozzles is typically configured to spray fluid in a predominantly two- dimensional fan over an angle of between 20° and 55°, or between 25° and 50°, or between 30° and 45°, e.g. 33°. The clearing fluid sources are typically angled so as to direct fluid towards the solid food matter blocking filter. The handle of the lid is typically coupled to a mechanism which, when the handle is used to open the lid (and/or to unlock the lid), prevents flow of fluid from the one or more clearing fluid sources (when the lid is in an open position), and when the handle is used to close the lid (and/or to lock the lid in a closed position), permits flow of fluid from the one or more clearing fluid sources (when the lid is in a closed position). The said mechanism typically comprises a tap having an open position in which fluid is permitted to flow from the one or more clearing fluid sources (when the lid is in a closed position) and a closed position in which fluid is prevented from flowing from the one or more clearing fluid sources (when the lid is in an open position). Typically, a void is provided between the filtering mesh and the solid food matter blocking filter (for example the shortest distance between the filtering mesh, when it is in its relaxed state, and the solid food matter blocking filter is at least 10%, at least 20%, at least 30%, at least 40% or at least 50% of a distance between a downstream end of the filtering mesh and the inlet to the filtering mesh). It may be that the shortest distance between the filtering mesh, when it is fully expanded, and the solid food matter blocking filter is at least 10%, at least 20%, at least 30%, at least 40% or at least 50% of a distance between a downstream end of the filtering mesh and the inlet to the filtering mesh. Typically, a void is provided between the supporting mesh and the solid food matter blocking filter when the supporting mesh is provided (for example the shortest distance between the supporting mesh and the solid food matter blocking filter is at least 10%, at least 20%, at least 30%, at least 40% or at least 50% of a distance between a downstream end of the supporting mesh and the inlet to the supporting mesh). It may be that the shortest distance between the supporting mesh, when it is fully expanded, and the solid food matter blocking filter is at least 10%, at least 20%, at least 30%, at least 40% or at least 50% of a distance between a downstream end of the supporting mesh and the inlet to the filtering mesh. Typically, a void is provided between the first and second (typically removable) interior chambers (for example the shortest distance between the first and second (typically removable) interior chambers is at least 10%, at least 20%, at least 30%, at least 40% or at least 50% of a length of the first (typically removable) interior chamber (the length being parallel (or substantially parallel) to the line of shortest distance between the first and second interior chambers and/or to the principle direction of flow between the first and second interior chambers). The void provided between the solid food matter blocking filter and the filtering mesh (and/or the supporting mesh when provided) allows for a more efficient removal of solid food matter from the mixture comprising solid food matter and water because it allows a flow of solid food matter and water to build up speed before it engages the solid food matter blocking filter, thereby helping the water to flow through the fine openings of the solid food matter blocking filter. The apparatus may further comprise a water filter configured to remove one or more water contaminants from a flow comprising predominantly liquid water. Typically, the water filter is located downstream of the solid food matter blocking filter. The water filter may be provided downstream of the second interior chamber (where provided). The apparatus may also comprise a water pump configured to pump (clean) water out of the second (typically removable) interior chamber to an outlet of the apparatus. The water pump may be provided within the second (typically removable) interior chamber. The water filter may be provided downstream of the water pump. The water pump may be configured to pump water which has passed through the solid food matter blocking filter down a drain. Alternatively, the water pump may be configured to pump water which has passed through the solid food matter blocking filter (back) into a food processing apparatus. In this case, it may be that an additional solid food matter blocking filter is provided between the water pump and the food processing apparatus. The said additional solid food matter blocking filter is typically configured to permit the flow of water therethrough but to inhibit the flow of solid food matter therethrough. The said additional solid food matter blocking filter may comprise a sock filter. The said additional solid food matter blocking filter may comprise a mesh having openings sized to permit the flow of water therethrough but to inhibit the flow of solid food matter therethrough. The said additional solid food matter blocking filter may comprise a mesh having openings larger than the openings of the mesh of the solid food matter blocking filter. Such an additional solid food matter blocking filter is typically configured to inhibit the flow of solid food matter particles which have passed through the solid food matter blocking filter and agglomerated to form larger particles of solid food matter. For example, the mesh of the additional solid food matter blocking filter may comprise openings having flow areas having largest dimensions of between 100 μιη and 500 μιη, or between 200 μιη and 500 μιη, or between 300 μιη and 500 μιη, for example around 400 μιη. Alternatively, the said additional solid food matter blocking filter may comprise a mesh having openings smaller than the openings of the mesh of the solid food matter blocking filter. In this case, for example, the mesh of the additional solid food matter blocking filter may comprise openings having flow areas having largest dimensions of between 30 μιη and 250 μιη, or between 50 μιη and 150 μιη, or between 70 μιη and 90 μηι.

It will be understood that the terms "upstream" and "downstream" are relative terms and they relate to relative positions in a process chain of the apparatus for separating solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) from a received mixture comprising water and solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch). Typically the process chain comprises: using the filtering mesh to remove (typically some but not all of the) solid food matter from a received input of water and solid food matter and typically directing fluid from the one or more fluid sources onto the received mixture comprising water and solid food matter (e.g. through the filtering mesh); next, optionally passing water and solid food matter through a or the supporting mesh; next, typically directing fluid from the one or more fluid sources onto a mixture comprising water and (typically some but not all of the) solid food matter which has passed through the filtering mesh (and optionally the supporting mesh); next, typically directing water and solid food matter which has passed through the filtering mesh to a solid food matter blocking filter; next, typically passing water through the solid food matter blocking filter and inhibiting solid food matter from flowing through the solid food matter blocking filter; next, typically filtering one or more water contaminants (such as soil) out of the water which has passed through the solid food matter blocking filter; next, optionally the flow output from the water filter may be passed through an additional solid food matter blocking filter (or this may occur prior to the water filter); next, typically either recycling the water which has been filtered or directing it down a drain. The term "downstream" relates to a later portion of the process chain and the term "upstream" relates to an earlier portion of the process chain. For example, the solid food matter blocking filter may have an upstream side and a downstream side. The upstream side is typically provided earlier in the said process chain than the downstream side (i.e. the water solid food matter mixture is incident on the upstream side of the solid food matter blocking filter and water passes through the upstream side of the solid food matter blocking filter and exits the solid food matter blocking filter through the downstream side). It will be understood that the term "mesh" is not limited to a mesh comprising square or rectangular openings. Indeed there is no requirement for the filtering or supporting meshes to have regular repeating patterns of openings. It is of course envisaged however that the term "mesh" covers these possibilities. In some embodiments, the apparatus for separating solid food matter from a received mixture comprising water and solid food matter is an apparatus for separating solid vegetable matter from a received mixture comprising solid vegetable matter and water. Typically, the filtering mesh is configured to inhibit a flow of (typically some but not all of the) solid vegetable matter therethrough and to allow passage of water therethrough. Typically, the supporting mesh is configured to suppress a surge of water and solid vegetable matter passing through the filtering mesh. Typically, the one or more fluid sources are configured to direct fluid onto the received mixture comprising solid vegetable matter and water and/or onto a mixture comprising water and solid vegetable matter which has passed through the filtering mesh. Typically, the fluid directed by the one or more fluid sources causes solid vegetable matter to move towards and aggregate upon an internal surface of the apparatus. Typically, the solid food matter blocking filter is configured to receive a mixture comprising water and solid vegetable matter which has passed through the filtering mesh, to inhibit a flow of solid vegetable matter therethrough and to allow passage of water therethrough. Typically, the one or more clearing fluid sources are configured to direct fluid (typically liquid) onto the solid vegetable matter blocking filter (typically a side of the solid vegetable matter blocking filter which extends predominantly in a plane perpendicular to a principle direction of flow of the mixture comprising water and solid vegetable matter output from the filtering mesh). The one or more clearing fluid sources may be configured to direct fluid onto an upstream side of the solid vegetable matter blocking filter. The one or more clearing fluid sources are typically configured to remove at least some of the solid vegetable matter from the upstream side of the solid vegetable matter blocking filter in use. It may be that the apparatus for separating solid food matter from a received mixture comprising water and solid food matter is an apparatus for separating potato peel and starch from a received mixture comprising potato peel, starch and water. Typically, the filtering mesh is configured to inhibit a flow of potato peel therethrough and to allow passage of water and starch therethrough. Typically the filtering mesh comprises a net (typically in the form of a bag having an inlet) configured to receive the received mixture comprising water, potato peel and starch. The net of the filtering mesh is typically configured to retain potato peel and to allow passage of water and starch therethrough. Typically, the supporting mesh is configured to (mechanically) support the filtering mesh. The supporting mesh typically comprises a net (typically provided in the form of a bag having an inlet) surrounding the filtering mesh. The supporting mesh is typically configured to suppress a surge of water and starch passing through the filtering mesh. Typically, the one or more fluid sources are configured to direct fluid onto the received mixture comprising potato peel, starch and water and/or onto a mixture comprising water and starch which has passed through the filtering mesh. Typically, the fluid directed by the one or more fluid sources causes starch to move towards and aggregate upon an internal surface of the apparatus (e.g. an internal surface of the solid food matter collecting vessel, where provided, which, in this case, comprises a starch collecting vessel). Typically, the solid food matter blocking filter is configured to receive a mixture comprising water and starch which has passed through the filtering mesh, to inhibit a flow of starch therethrough and to allow passage of water therethrough. Typically at least part of the solid food matter blocking filter extends predominantly in a plane perpendicular to a principle direction of flow of the mixture comprising water and starch output from the filtering mesh (and, where provided, typically the supporting mesh). Typically, the one or more clearing fluid sources are configured to direct fluid (typically liquid) onto the solid food matter blocking filter (typically a side of the solid food matter blocking filter which extends predominantly in a plane perpendicular to a principle direction of flow of the mixture comprising water and starch output from the filtering mesh). The one or more clearing fluid sources may be configured to direct fluid onto an upstream side of the solid food matter blocking filter. The one or more clearing fluid sources are typically configured to remove at least some of the starch from the upstream side of the solid food matter blocking filter in use. The potato peeler may comprise a wet potato peeler, that is to say a potato peeler which receives a (typically cool) water input and uses the input water in the peeling process. In this case, the water in the water and solid food matter mixture may comprise water received and used by the potato peeler in the peeling process. Additionally, the water in the water and solid food matter mixture typically comprises water extracted from the potatoes themselves during the peeling process. In other embodiments, the potato peeler may be a dry potato peeler, that is to say a potato peeler which does not receive a water input for use in the peeling process. In this case, the water in the water and solid food matter mixture typically comprises water extracted from the potatoes during the peeling process. A second aspect of the invention provides a system comprising apparatus for separating solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) from a received mixture comprising water and solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) according to the first aspect of the invention and a food processing apparatus (for example a vegetable peeler, such as a potato peeler or other root vegetable peeler) in communication with the apparatus for separating solid food matter from a received mixture comprising water and solid food matter, the apparatus for separating solid food matter from a received mixture comprising solid food matter and water being configured to receive a mixture comprising solid food matter and water from the food processing apparatus. Typically the food processing apparatus (for example a vegetable peeler, such as a potato peeler or other root vegetable peeler) is configured to output a mixture comprising water and solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) to an inlet (e.g. an inlet of the filtering mesh) of the apparatus for separating solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) from the received mixture comprising solid food matter and water. The apparatus for separating solid food matter typically comprises a water outlet. The food processing apparatus typically comprises a water inlet. The water outlet of the apparatus for separating solid food matter may be in fluid communication with the water inlet of the food processing apparatus such that water is recycled from the apparatus for separating solid food matter to the food processing apparatus (which may be for example a wet potato peeler). It will be understood that, as indicated above with respect to the first aspect of the invention, it may be that the apparatus for separating solid food matter from a received mixture comprising water and solid food matter is an apparatus for separating solid vegetable matter from a received mixture comprising solid vegetable matter and water. In this case, the food processing apparatus typically comprises a vegetable processing apparatus configured to output a mixture comprising solid vegetable matter and water. It will also be understood that, as indicated above with respect to the first aspect of the invention, it may be that the apparatus for separating solid food matter from a received mixture comprising water and solid food matter is an apparatus for separating potato peel and starch from a received mixture comprising potato peel, starch and water. In this case, the food processing apparatus typically comprises a potato peeler configured to output a mixture comprising potato peel, starch and water. A third aspect of the invention provides a kit of parts comprising: a filtering mesh (typically having an inlet); a container for housing the filtering mesh (the container typically having an inlet sized for fluid communication with the inlet of the filtering mesh); and one or more fluid sources mountable or mounted to an internal surface of (e.g. an internal surface of a lid of) the container and configurable or configured to direct fluid towards the filtering mesh or onto an input to or an output from the filtering mesh. The filtering mesh is typically demountably retainable in the container. The fluid sources are typically demountably retainable on the said internal surface of the container. The filtering mesh may have any of the features discussed above in respect of the first aspect of the invention. The kit of parts may further comprise a (first) interior chamber within (or at least sized to fit within) the main container. The (first) interior chamber is typically removable from the main container. The (first) interior chamber typically comprises one or more perforated or honeycombed walls. The kit of parts may further comprise a second interior chamber within (or at least sized to fit within) the container together with the first interior chamber. The second interior chamber is typically removable from the main container. The second interior chamber typically comprises one or more perforated or honeycombed walls. The first and second interior chambers may be provided within (or sized to fit within) the container together with a void between them (e.g. the shortest distance between the first and second chambers may be at least 10%, at least 20%, at least 30%, at least 40% or at least 50% of a length of the first interior chamber). The first and second interior chambers are typically configurable to be in fluid communication with each other (e.g. through perforated walls of the first and second chambers) when provided within the container. Typically, the filtering mesh is sized to fit within the first interior chamber. Typically, the filtering mesh comprises a net. Typically, the net of the filtering mesh is expandable (e.g. expandable in volume by at least 50%, at least 60%, at least 70%, at least 80%, at least 90% or at least 100% of its relaxed volume). Typically, the net of the filtering mesh is sized to fit within the first interior chamber when fully expanded. Typically the net of the filtering mesh comprises an inlet which is demountably mountable to an inlet of the container and/or to an inlet of the first interior chamber. Typically the net of the filtering mesh is provided in the form of a bag. The container (and typically the first interior chamber and typically the net of the filtering mesh) typically comprises an inlet for receiving a mixture comprising solid food matter and water. It may be that the kit of parts comprises a supporting mesh. Typically, the supporting mesh is sized to fit within the container (typically together with the filtering mesh). The supporting mesh is typically sized to fit within the first interior chamber (typically together with the filtering mesh). Typically the supporting mesh is demountably retainable within the first interior chamber. Typically, the supporting mesh comprises a net. Typically the net of the supporting mesh is provided in the form of a bag. Typically, the net of the supporting mesh is expandable (e.g. expandable in volume by at least 50%, at least 60%, at least 70%, at least 80%, at least 90% or at least 100% of its relaxed volume). Typically, the net of the supporting mesh is sized to fit within the first interior chamber (together with the filtering mesh) when fully expanded. Typically the net of the supporting mesh comprises an inlet which is demountably mountable to an inlet of the container and/or to an inlet of the first interior chamber and/or to the inlet of the net of the filtering mesh. The supporting mesh may have any of the features discussed above in respect of the first aspect of the invention. The net of the filtering mesh is typically sized to fit within the net of the supporting mesh (if either or both are expandable, typically at least when both are in their relaxed states). In embodiments where both the net of the filtering mesh and the net of the supporting mesh are expandable, the net of the filtering mesh is typically sized to fit within the net of the supporting mesh when both are in their (fully) expanded states. The kit of parts may also comprise a solid food matter blocking filter. The solid food matter blocking filter typically comprises a (mechanical) mesh having a plurality of openings sized to permit flow of water therethrough but to inhibit flow of solid food matter therethrough. The solid food matter blocking filter may comprise a metallic (for example, stainless steel) mesh. The solid food matter blocking filter is typically mounted on or mountable to a (typically perforated or honeycombed) wall of the second interior chamber. The solid food matter blocking filter may be configured to cover at least 50%, more preferably at least 75%, more preferably 100% of a surface area of a (typically perforated or honeycombed) wall of the second interior chamber. The said wall of the second interior chamber is typically sized to extend at least 60%, more preferably at least 80%, even more preferably at least 90% of the way between opposing walls of the main container (typically perpendicular to a principle direction of the flow of water from the first interior chamber to the second interior chamber when the apparatus is assembled and in use). It will be understood that the solid food matter blocking filter may be configured to cover at least 50%, more preferably at least 75%, more preferably 100% of a surface area of each of a plurality of (typically perforated or honeycombed) walls of the second interior chamber. The solid food matter blocking filter may have any of the features of the solid food matter blocking filter described above in respect of the first aspect of the invention. The kit of parts may further comprise (e.g. silicone) sealant for sealing between the edges of the solid food matter blocking filter and the wall of the second interior chamber. Typically, the kit of parts comprises one or more clearing fluid sources mounted or mountable to an internal surface (e.g. an internal surface of a lid) of the container and configured or configurable to direct fluid onto the solid food matter blocking filter. Typically, the one or more clearing fluid sources are configured or configurable to direct fluid onto an upstream side of the solid food matter blocking filter. Typically the clearing fluid sources are demountably retainable to the internal surface of the lid. The fluid sources and the clearing fluid sources typically comprise spray nozzles. The kit of parts may further comprise a water filter. The kit of parts may also comprise a water pump. The kit of parts may comprise an additional solid food matter blocking filter (which may, for example, comprise a sock filter). The additional solid food matter blocking filter may have any of the features discussed above in respect of the first aspect of the invention. The kit of parts may comprise any other parts set out above in respect of the first and second aspects of the invention. A fourth aspect of the invention provides a method of separating solid food matter (for example vegetable peel, such as potato peel or other root vegetable peel) from a received mixture comprising solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) and (liquid) water, the method comprising: removing at least some of the solid food matter (for example solid vegetable matter, such as potato peel or other root vegetable peel and/or starch) from the received mixture comprising solid food matter and water using a filtering mesh; and removing at least some of the solid food matter from the received mixture comprising solid food matter and water by directing fluid onto the said received mixture comprising solid food matter and water and/or removing at least some solid food matter from a mixture comprising water and solid food matter which has passed through the filtering mesh by directing fluid onto said mixture comprising solid food matter and water which has passed through the filtering mesh. Typically, the method further comprises suppressing a surge of water and solid food matter passing through the filtering mesh using a supporting mesh in fluid communication with (and typically downstream of) the filtering mesh. Typically, the supporting mesh carries the filtering mesh (i.e. the filtering mesh is typically housed within the supporting mesh). The supporting mesh is also typically configured to inhibit the flow of solid food matter therethrough. The supporting mesh may be identical to the filtering mesh. As set out in respect of the first aspect of the invention, the filtering mesh (and typically the supporting mesh, where provided) is (are) typically housed within a first interior chamber of a main container. Typically the method comprises directing solid food matter from the received mixture comprising solid food matter and water and/or from a mixture comprising water and solid food matter which has passed through the filtering mesh towards an internal surface of the first interior chamber by directing fluid onto said mixture (e.g. from the one or more fluid sources). Typically the method comprises compacting said solid food matter onto said internal surface of the main container (e.g. using fluid from one or more fluid sources). Typically the method comprises aggregating said solid food matter upon an internal surface of the said first interior chamber (e.g. upon an internal surface of a solid food matter collecting vessel of the first interior chamber) and/or an internal surface (for example, a base) of the main container. Typically the method comprises collecting solid food matter removed from the received mixture comprising solid food matter and water and/or from the mixture comprising solid food matter and water which has passed through the filtering mesh in a solid food matter collecting vessel. Preferably, the method further comprises removing at least some of the solid food matter from the mixture comprising water and solid food matter which has passed through the filtering mesh (and/or the supporting mesh when provided) using a solid food matter blocking filter. Typically, the method further comprises removing solid food matter from the solid food matter blocking filter by directing clearing fluid onto the said solid food matter blocking filter (e.g. from one or more clearing fluid sources). Typically, fluid is directed onto the said solid food matter blocking filter by the one or more clearing fluid sources. Typically fluid is directed onto the said solid food matter blocking filter by the one or more clearing fluid sources in a predominantly two-dimensional fan over an angle of between 20° and 55°, or between 25° and 50°, or between 30° and 45° (e.g. 33°). The method may further comprise the step of removing one or more water contaminants from the water passing through the solid food matter blocking filter (thereby cleaning the water). The method may further comprise removing solid food matter from the mixture comprising water and solid food matter which has passed through the said solid food matter blocking filter using an additional solid food matter blocking filter. The method may further comprise the step of disposing of the (cleaned) water down a drain. Additionally or alternatively, the method further comprises reusing the (cleaned) water (e.g. in a food processing apparatus or to provide an input to the fluid or clearing fluid sources). Any features described in relation to any one aspect of the invention may be features of any embodiments of any other aspect of the invention where applicable. Description of the Drawings An example embodiment of the present invention will now be illustrated with reference to the following Figures in which: Figure 1 is a block diagram of a system for separating potato peel and starch from an output from a potato peeler; Figure 2 is a perspective view of the filtration apparatus of Figure 1 with its lid open; Figure 3 is a top-down view of the filtration apparatus of Figure 1 with its lid not shown; Figure 4 is a top-down view of the filtration apparatus of Figure 1 with its lid closed; Figure 5 is a side view of the filtration apparatus of Figure 1 ; Figure 6 is a side view of the filtration apparatus of Figure 1 when the filtration apparatus is in use. Detailed Description of an Example Embodiment Figure 1 is a block diagram of a system for separating potato peel and starch from an output from a wet potato peeler 1 (i.e. a potato peeler which uses water in the peeling process) comprising a mixture comprising potato peel, starch and water and other water contaminants (such as soil). The output from the potato peeler 1 is received by a filtration apparatus 2. The filtration apparatus 2 further receives a flow of water 3 from a water main 4. The filtration apparatus 2 filters out potato peel and starch from the mixture comprising potato peel, starch and water, and outputs water 5 to a drain 6. Optionally, some or all of the water 5 output by the filtration apparatus 2 may be returned to the potato peeler 1 or to the filtration apparatus 2 for reuse. The filtration apparatus 2, shown in more detail in Figures 2, 3, 4 and 5, comprises a generally cuboidal container 7 having four walls 7a, 7b, 7c and 7d extending upwards from edges of a base 7e, and a lid 8 hingedly mounted to wall 7a by hinges 9a and 9b. The lid 8 may be opened and closed by pivoting the lid 8 about hinges 9a and 9b. The container 7 further comprises a first interior chamber 10 defined by four walls 10a, 10b, 10c and 10d extending upwards from edges of a base 10e, and a second interior chamber 1 1 defined by four walls 1 1 a, 1 1 b, 1 1c and 1 1 d extending upwards from edges of a base 1 1 e. The first and second interior chambers 10 and 1 1 are separated from one another by a void 12 such that they do not together occupy all the interior space of the container 7. The container 7, and the first and second interior chambers 10 and 1 1 , are typically made from a metallic material, for example stainless steel. The lid 8 is typically made from a transparent plastics material. The walls 10a, 10c and 10d of the first interior chamber 10 and the walls 1 1a, 1 1 b, 1 1 c and 1 1 d of the second interior chamber 1 1 are perforated such that water and starch may pass through them. The wall 10b of the first interior chamber is not perforated (that is, it typically comprises a solid sheet of material). A starch collecting vessel 10f defined by three walls 10g, 10h and 10i (see Figure 3 in particular) and the (non- perforated) wall 10b and the base 10e of the first interior chamber 10 is formed within the first interior chamber 10. The walls 10g, 10h and 10i have heights smaller than the heights of the walls 10a, 10c and 10d respectively (for example, the walls 10g, 10h and 10i have heights less than 20%, less than 10 % or less than 5% of the heights of walls 10a, 10c and 10d respectively). The walls 10g, 10h and 10i are impermeable to water and starch such that they form a partial barrier to starch flow between the first interior chamber and the void 12. The surface of the wall 1 1 b of the second interior chamber 1 1 , facing wall 10d of the first interior chamber 10, is covered by a starch blocking filter 13. The starch blocking filter comprises a stainless steel mesh whose openings are sized (e.g. the openings may have flow areas through which water can flow from an upstream side of the starch blocking filter to a downstream side thereof, the flow areas having a largest dimension of around 90μιη-120μιη) such that water may pass through them but starch is inhibited from passing through them. An inlet 14 which is configured to communicate fluidly with the output of the potato peeler 1 is provided which extends through central portions of the walls 7b and 10b of the container 7 and the first interior chamber 10 respectively. The first interior chamber 10 houses a filtering mesh in the form of a filtering net 15 comprising an inlet fluidly communicating with and attached to the inlet 14 of the first interior chamber 10. The net 15 is thus configured to receive an input of potato peel, starch and water from the potato peeler 1 through said inlet 14. The openings of the filtering net 15 are sized such that water and starch may pass through them, but (particularly larger) pieces of potato peel are inhibited from passing through them. The filtering net 15 is surrounded by a supporting mesh in the form of a supporting net 16. The supporting net 16 surrounds the majority of the filtering net 15 except around the inlet 14. The openings of the supporting net 16 have the same size as those of the filtering net 15. The filtering net 15 and the supporting net 16 are expandable nets made from resilient material (such as plastics threads or fibres, for example nylon). The filtering net 15 and the supporting net 16 are secured to the inlet 14 by way of fast-release connections so as to allow the filtering net 15 and the supporting net 16 to be removed easily for cleaning or replacement. The second interior chamber 1 1 contains a water pump 17 in fluid communication with an outlet pipe 18. The outlet pipe 18 is further in fluid communication with an external water filter 19 downstream of the outlet pipe 18. The water pump 17 functions to pump water out of the second interior chamber 1 1 , through the outlet pipe 18, and into the water filter 19. The outlet pipe 18 is made from a plastics material. The outlet pipe 18 is secured to the water pump 17 by way of fast release connections. Mounted on an internal surface of the lid 8 are water spray nozzles 20a, 20b, 20c, and 20d. The water spray nozzles 20a, 20b, 20c and 20d are configured to spray water into the first interior chamber 10 and onto and around the filtering net 15 and the supporting net 16 when the lid 8 is closed on top of the container 7 and the filtration apparatus 2 is in use. Typically each of the spray nozzles 20a-20d is configured to direct fluid onto different portions of the filtering net 15 and the supporting net 16, but there is typically some overlap as to where at least two of the nozzles (and typically where at least the four nozzles 20a-20d) direct fluid (e.g. the region of overlap typically comprises a central portion of the filtering net 15 and a central portion of the supporting net 16). Also mounted to the internal surface of the lid 8 (downstream of the water spray nozzles 20a-20d) are directional clearing spray nozzles 21a and 21 b. The directional clearing spray nozzles 21a and 21 b are angled to spray water towards a surface of the starch blocking filter 13 when the lid 8 is closed on top of the container 7 and the apparatus 2 is in use. With reference to Figure 4, an exterior surface of the lid 8 supports tubing 22 which fluidly connects the water spray nozzles 20a, 20b, 20c and 20d, and the clearing spray nozzles 21a and 21 b, to the water source 4 (for example, the mains water supply). The tubing 22 is made from a plastics material, but may be made from any suitable material. When the lid 8 is closed and the apparatus 2 is in use, the tubing 22 provides a flow of water to the water spray nozzles 20a, 20b, 20c and 20d, and the clearing spray nozzles 21 a and 21 b, such that they spray water into the container 7. Each of the water spray nozzles 20a, 20b, 20c and 20d and the clearing spray nozzles 21a and 21 b spray water in a predominantly two-dimensional fan over an angle between 30° and 45°. A handle 28 is also mounted on the exterior surface of the lid 8. The handle 28 comprises a mechanism operating as a tap to control flow of water to the water spray nozzles 20a, 20b, 20c and 20d, and the clearing spray nozzles 21a and 21 b. When the lid 8 is open, the mechanism of the handle 28 prevents water flowing through the tubing 22 to the water spray nozzles 20a, 20b, 20c and 20d, and the clearing spray nozzles 21 a and 21 b. When the lid 8 is closed and the apparatus is in use, the mechanism of the handle 28 permits water to flow through the tubing 22 to the water spray nozzles 20a, 20b, 20c and 20d, and the clearing spray nozzles 21 a and 21 b. Although not shown in the figures, a cover may be provided over the tubing 22. With reference to Figure 6, when the lid 8 is closed and the apparatus 2 is in use, a mixture comprising water, potato peel and starch flows from the potato peeler 1 into the apparatus 2 through the inlet 14. As the filtering net 15 fills, it expands. The openings in the filtering net 15 are sized to retain the potato peel 27 within the filtering net 15 even when the net is expanded, but to allow water and starch to be squeezed out, forming a flow. The supporting net 16 functions to mechanically support the filtering net 15 and to suppress any sudden surge of starch and water seeping or foaming out of the filtering net 15. The openings of the supporting net 16 are sized to allow a mixture comprising water and starch to pass through them and to inhibit any peel which enters the supporting net 16 through the filtering net 15 from passing through the supporting net 16. The mixture comprising water and starch 24 passing through the filtering net 15 and the supporting net 16 flows into the first interior chamber 10. The water spray nozzles 20a, 20b, 20c and 20d spray respective sprays of water 23a, 23b, 23c and 23d onto and around the filtering net 15 and the supporting net 16. The sprays of water 23a, 23b, 23c and 23d wash away starch and water passing through the filtering net 15 and the supporting net 16 such that the two nets are continuously rinsed, facilitating passage of further quantities of starch and water therethrough. The sprays of water 23a, 23b, 23c and 23d also cause water to pass through the filtering net 15 and the supporting net 16 and rinse starch out of the mixture comprising potato peeler, water and starch retained within the filtering net 15. The sprays of water 23a, 23b, 23c and 23d also direct the starch in the first interior chamber 10 towards the base 10e such that the starch forms a first aggregate starch layer 26 on the base 10e. The walls of the vessel 10f (particularly wall 10i) act as a barrier to starch flow between the first interior chamber and the void 12 such that starch aggregating upon the base 10e is retained in the vessel 10f and does not escape into the void 12. The sprays of water 23a, 23b, 23c and 23d also compact the starch against the base 10f. In general, material flows inside the apparatus in a direction from the inlet 14 to the outlet pipe 18. Some of the mixture comprising water and starch 24 inside the first interior chamber 10 passes through the perforated walls 10a, 10b, 10c and 10d and into the void 12. The presence of the void 12 allows the flow of the water and starch mixture passing through the nets to build up speed before it reaches the starch blocking filter 13, helping the water to pass through the fine openings of the starch blocking filter 13. The water from the water and starch mixture passes through the starch blocking filter 13 and the perforated wall 1 1 b to enter the second interior chamber 1 1. The remaining starch in the water and starch mixture cannot pass through the starch blocking filter 13 and is instead retained on an upstream side of said starch blocking filter 13. The clearing spray nozzles 21a and 21 b direct respective clearing sprays of water 25a and 25b onto the upstream side of the starch blocking filter 13. The clearing sprays of water 25a and 25b thereby remove some of the starch retained on the upstream side of the starch blocking filter 13 and cause it to move towards and aggregate upon the base 7e of the container 7, forming a second aggregate starch layer 27. The water which is able to pass into the second interior chamber 1 1 is pumped into the outlet pipe 18 by the water pump 17. The water then flows through the outlet pipe 18 to the water filter 19, which removes some further contaminants from the water. The outlet pipe 18 can be connected to the drain 6 to dispose of the now clean waste water, or the water can be recycled, for example in further potato peeling or filtration operations. In embodiments where the waste is recycled, it may be that a further filter (such as a sock filter comprising a mesh having openings with flow areas therethrough having a largest dimension of around 400μιη or less) is provided between the water filter 19 and the apparatus to which the water is recycled. The further filter may remove large particles of starch which have agglomerated from smaller particles of starch which have passed through the starch blocking filter 13. When the process is complete and the apparatus is no longer in use, potato peel 27 will be retained within the filtering net 15. This can be removed easily from the first interior chamber 10 for solid waste disposal purposes by releasing the fast release connection attaching the filtering net 15 to the inlet 14. The first and second aggregate starch layers 26 and 27 can also be removed from the first interior chamber 10 and the container 7 respectively for either solid waste disposal or recycling. Other variations of the materials and parameters disclosed in the description are possible. For example, the container 7, the first interior chamber 10 and the second interior chamber 1 1 may be made from any suitable material not limited to stainless steel. The lid 8 may be made from a transparent plastics material, but it may also be made from a non-transparent plastics material or a metallic material. The filtering net 15 and the supporting net 16 may be made from any suitably resilient, flexible or expandable (or indeed non-resilient, non-flexible or non-expandable) materials not limited to plastics such as nylon. The outlet pipe 18 may also be made from any suitable material, not limited to a flexible plastics material. It may be, for example, that the outlet pipe 18 is a rigid pipe made of a metallic or plastics material. Further variations and modifications may be made within the scope of the invention herein disclosed.
