Description:
BEVERAGE PREPARATION DEVICE WITH THERMALLY OPTIMISED ARCHITECTURE

Field of the Invention

The field of the invention pertains to beverage preparation machines which uses thermally conditioned liquid, such as heated and/or cooled liquid. The liquid is typically water or water-based. The machine may be configured to prepare the beverage by passing the liquid through a capsule containing an ingredient of the beverage to be prepared, such as at least one of coffee, tea, cacao, milk, sugar and/or soup ingredient. For instance, the liquid is mixed with the ingredient contained in the capsule by centrifuging the capsule while the liquid is passed through the capsule.

For the purpose of the present description, a "beverage" is meant to include any human-consumable liquid substance, such as tea, coffee, hot or cold chocolate, milk, soup, baby food, etc... A "capsule" is meant to include any container such as a packaging for containing a pre-portioned beverage ingredient, e.g. a flavouring ingredient, the packaging forming an enclosure of any material, in particular an airtight or pervious material, porous or non-porous material, e.g. plastic, aluminium, recyclable and/or biodegradable packagings, and of any shape and structure, including soft pods or rigid cartridges for containing the ingredient.

Background Art

Certain beverage preparation machines use capsules containing ingredients to be extracted or to be dissolved and/or ingredients that are stored and dosed automatically in the machine or else are added at the time of preparation of the drink. Some beverage machines possess filling means that include a pump for liquid, usually water, which pumps the liquid from a source of water that is cold or indeed heated through heating means, e.g. a thermoblock or the like.

Especially in the field of coffee preparation, machines have been widely developed in which a capsule containing beverage ingredients is inserted in a brewing device. The brewing device is tightly closed about the capsule, water is injected at the first face of the capsule, the beverage is produced in the closed volume of the capsule and a brewed beverage can be drained from a second face of the capsule and collected into a receptacle such as a cup or glass.

The preparation of a beverage by using centrifugation is known. Such beverage preparation includes: providing a beverage (flavoring) ingredient, e.g. as powder and/or leaves, in a capsule; circulating liquid into the capsule and rotating the capsule at sufficient speed to ensure interaction of the liquid with the ingredient while creating a gradient of pressure of liquid in the capsule. Such pressure increases gradually from the center towards the periphery of the capsule. As liquid traverses the ingredient, e.g. coffee bed, extraction of the ingredient, e.g. coffee compounds, takes place and a liquid extract is obtained that flows out at the periphery of the capsule. Examples of such systems are disclosed in W02008/ 148601 , WO 2013/007776, WO 2013/007779 and WO 2013/007780.

When no appropriate measure is taken, centrifugal systems suffer the inconvenience that the liquid extract discharged from the device is exposed to significant heat exchange with the environment which leads to a beverage that can be significantly colder or hotter than desired. In particular, the liquid extract can cool down (if the liquid is previously heated) or warm up (if the liquid is previously cooled) in the collecting device by heat exchange with the large surfaces of the collector of the device. This results from the fact that the brewing unit is rotated along a central axis to form a thin layer or jets of liquid impacting on a substantially tubular impact surface. The liquid comes in contact with and drip from a surface that can be equal, for instance, to a first impact surface which, when it is cylindrical, may have a surface area of at least about 500 mm 2 . Furthermore, if the liquid is then collected in a generally U-shaped cavity that leads to a dispensing duct, such cavity forms again extensive areas of contact with the extracted liquid. Furthermore, the receptacle such as a cup further cools the liquid down unless it has been heated before being placed under the device for the reception of the liquid.

Furthermore, certain beverage ingredients, such as roast and ground coffee or tea, must be brewed with a heated liquid, e.g., hot water, within a particular range of temperature to ensure the full extraction of the ingredients including the capture of the desired aroma compounds. Therefore, the liquid supplied in the brewing unit cannot be overheated to compensate for the temperature losses endured by the liquid after extraction as it would negatively affect the quality of extraction. The range of temperatures for an optimal brewing such as for coffee or tea must be so respected for ensuring the best quality of the final beverage. Furthermore, other quality characteristics of the coffee beverage must be preserved during preparation such as the head of foam called "crema" .

It is already known from EP 2393404 A1 to compensate for a temperature loss in a device as described above by using additional heating elements, but these devices are very complex.

Advantageous systems to manage the temperatures of the liquid before mixing it with the beverage flavouring ingredient and of the resulting beverage are disclosed in WO 2010/089329 and in WO 2014/090850.

There is still a need to optimise the thermal management of the liquid before and after mixing it with the beverage flavouring ingredient.

Summary of the Invention

The invention relates to a capsule processing machine for preparing a beverage from at least one ingredient. Normally such beverage is then dispensed to a user, e.g. to a user-cup or user-mug.

For instance, the machine is a coffee, tea, chocolate, cacao, milk or soup preparation machine. For example, the machine is arranged for preparing within a beverage processing module that includes the capsule holder, a beverage by passing hot or cold water or another liquid through a capsule held in the holder containing an ingredient, such as a flavouring ingredient, of the beverage to be prepared, such as ground coffee or tea or chocolate or cacao or milk powder .

Such beverage preparation typically includes the mixing of a plurality of beverage ingredients, e.g. water and milk powder, and/or the infusion of a beverage ingredient, such as an infusion of ground coffee or tea with water. For instance, a predetermined amount of beverage is formed and dispensed on user-request, which corresponds to a serving. The volume of such a serving may be in the range of 15 to 1000 ml such as 25 to 600 ml for instance 40 to 250 ml, e.g. the volume for filling a cup or mug, depending on the type of beverage. Formed and dispensed beverages may be selected from ristrettos, espressos, lungos, cappuccinos, cafe latte, americano coffees, teas, etc... For example, a coffee machine may be configured for dispensing espressos, e.g. an adjustable volume of 20 to 60 ml per serving, and/or for dispensing lungos, e.g. a volume in the range of 70 to 200 ml per serving, and/or for dispensing americanos, e.g. a volume in the range of 150 to 750 ml.

An aspect of the invention relates to a capsule processing machine for preparing a beverage from a capsule having a body containing a flavouring ingredient, e.g. coffee or tea or cacao or milk, by passing water into such capsule so as to be mixed with the flavouring ingredient in the capsule. For instance, the mixing is achieved by centrifugally driving such capsule.

The capsule may have a body containing an ingredient and a peripherally projecting flange.

The capsule may be of the type described above under the header "field of the invention". The capsule may be a capsule that has a container-body, e.g. a generally cup shaped or hemispherical or hemi-ellipsoidal body, having a flange to which a cover lid is attached, in particular sealed. Typically the capsule contains a beverage ingredient . The capsule may have a or the above body that is symmetric or asymmetric, conical or frusto-conical , pyramidal or frusto-pyramidal , cylindrical or prismatic, spherical or hemispherical or frusto-spherical , domical or frusto-domical , containing the ingredient, e.g. ground coffee, tea or cacao or another beverage ingredient.

The machine has a beverage processing unit.

Such unit includes a holder delimiting a receiving space for receiving the capsule. For instance, the receiving space delimits a holder cavity having an upwardly or sidewardly or slantingly (between upwardly and sidewardly) oriented mouth via which the capsule is received in the holder (e.g. opening delimited by a holder' s rim) , such as a mouth generally contained in a horizontal plane. The capsule may have a or the above capsule flange that extends generally in parallel to the mouth. The holder cavity may be shaped generally as a cup, e.g. to match the shape of the capsule.

The unit has a cover, such as a lid, for covering the holder. The cover and the holder are relatively movable: from an open position for placing said capsule into the receiving space and/or removing the capsule from the receiving space; into a closed position for preparing said beverage from said capsule in the receiving space.

The capsule holder and/or the cover may be drivable in rotation by a motorized drive axis, e.g. for centrifugation of the capsule.

For instance, the machine incorporates the features disclosed in WO 2008/148604, WO 2009/106598, WO 2014/096122 or WO 2014/096123.

The unit has a beverage outlet arrangement extending between the holder and the cover and/or through the cover. The outlet arrangement is configured to deliver the beverage from the processing unit. The outlet arrangement can be formed by a plurality of interstices between the holder and the cover. For instance, the interstices are delimited by a peripheral part of the cover and a facing interface face of the capsule, e.g. a peripheral flange of the capsule. For example, the outlet arrangement is in a generally horizontal and/or planar arrangement at a periphery of the cover facing the holder in the closed position of the cover and the holder.

Examples of outlet arrangements are disclosed in WO 2009/106175, WO 2012/100836, WO 2013/020939 and WO 2017/068134.

The unit includes a water inlet extending through the cover. The inlet is configured to guide water into the receiving space where it is mixed with the flavouring ingredient in the capsule to form the beverage.

The inlet may include the features disclosed in WO 2010/063644.

The capsule holder and cover can be incorporated into an ingredient processing module of a beverage preparation device, typically of the centrifugal type, e.g. as disclosed in EP 2 000 062, EP 2 155 020, EP 2 152 128, WO 2008/148646, WO 2008/148650, WO 2008/148834, WO 2009/106175, WO 2009/106589, WO 2010/026045, WO 2010/026053, WO 2010/063644, WO 2010/066705, WO 2010/066736 and WO 2011/023711.

The capsule holder and cover may be secured together in their closed position by a corresponding arrangement, e.g. as disclosed in WO 2012/007293 and WO 2014/102048.

The machine may have a capsule transfer device, e.g. as disclosed in WO 2012/041605, WO 2017/046294 and WO 2017/202746.

The processing unit may be fitted with an arrangement for opening the capsule, e.g. as disclosed in WO 2008/148656, WO 2010/026045 and WO 2010/066736.

The processing unit may be configured for receiving capsules of different sizes, e.g. as disclosed in WO 2011/023711.

The machine has a thermal conditioner, such as a heater and/or a cooler, that has a body forming a thermally conditioned beverage collecting surface. This collecting surface may delimit at least part of an annular cavity facing, e.g. surrounding, the outlet arrangement .

For instance, the cavity is generally U-shaped in cross-section. The annular cavity may have an outer beverage impact wall and an inner beverage confinement wall and a lower bottom. For example, the impact wall and/or the confinement wall is/are formed by the conditioner's body. The bottom may be formed by the conditioner' s body or by a component that is thermally substantially distinct thereto and that is significantly less thermally conductive than the conditioner's body.

The collecting surface may include the features disclosed in WO 2013/020940.

The thermally conditioned beverage collecting surface is configured to collect and thermally condition the beverage delivered from the outlet arrangement.

The body of the thermal conditioner is configured to thermally condition in the body the water for delivery into the inlet, such as into the inlet via a water conduit fluidically connecting the thermal conditioner and the inlet.

The machine may have a selection arrangement, such as a control unit and connected thereto at least one of a user-interface and a capsule recognition arrangement, configured to select a particular volume of water of a plurality of selectable available volumes to be supplied to said water inlet for preparing a correspondingly resulting particular volume of said beverage. For instance, the selectable available volumes include about 15 ml, about 20 ml, about 25 ml, about, 30 ml, about 35 ml, about 40 ml and so on until about 200, 400, 700 or even 1000 ml. Examples of preparation regulations are disclosed in WO 2010/026053, WO 2014/090965 and PCT/EP18/ 085737.

An automatic capsule recognition system may be used to parameterize and adjust the processing of the ingredient automatically in line with the type of ingredient. Examples of such technologies and associated features are disclosed in WO2011/141532, WO2011/141535, WO 2012/010470, WO 2013/072239, WO 2013/072297, WO 2013/072326, WO 2013/072351 and WO 2015/044400.

Examples of user-interfaces are disclosed in WO 2015/096998. The thermal conditioner body forms a conditioner cavity that delimits or contains at least partly the cover .

The conditioner cavity may delimit or contain the cover when the holder and the cover are in the closed position and when the holder and the cover are in the open position.

The conditioner' s body may surround entirely the beverage processing unit at a level of the unit's beverage outlet arrangement.

It follows that the thermal conditioner that thermally conditions the beverage flowing out of the beverage processing unit and that thermally conditions the water that flows into the beverage unit, is located closely to the inlet and to the outlet arrangement of the beverage processing unit, so that the liquid paths (water path and beverage path) between the thermal conditioner and the processing unit can be small and that thermal perturbations along these paths can be reduced accordingly. The beneficial effect is increased by having both the inlet and outlet arrangement on and/or at the same part of the beverage processing unit, i.e. the cover .

In an embodiment, the machine has a frame or outside housing that is stationary when the beverage is being prepared from the capsule in the receiving space, the cover being movable relative to the frame or housing between the open and closed positions. For instance, the holder is stationary relative to the frame or outside housing when the cover and the holder are relatively moved between the open and closed positions.

The thermal conditioner can be movable together with the cover relative to the frame or outside housing.

The cover may be pivotally and/or translationally movable relatively to the frame or outside housing along a guiding structure.

The cover can be pivotable relative to the frame or outside housing about a pivoting axis that is remote from the thermal conditioner. The pivoting axis and the thermal conditioner may be spaced by a spacing distance that is greater than a greatest dimension of the receiving space. Hence, the spacing can be such as to allow a passage of a capsule, e.g. after use of the capsule in the processing unit.

For example, the machine has a functional block, such as a used capsule reservoir and/or a water reservoir. The cover may be pivotable relative to the frame or outside housing about the pivoting axis that is remote from the thermal conditioner. The functional block or an access to the functional block may be located in a space spacing the pivoting axis and the receiving space.

The cover may be pivotable relative to the frame or outside housing about a pivoting axis that is remote from the thermal conditioner. The cover may be connected to the pivoting axis by a connection member. The connection member may cover a or the above functional block when the cover and the holder are in the closed position and may uncover the functional block when the cover and the holder are in the open position. For instance, the connection member forms an upper housing part.

At least one of the holder and the cover may be connected to a driver that is arranged to drive the holder and the cover in rotation when the holder and the cover are in the closed position. For instance, the driver is configured to centrifuge the receiving space containing the flavouring ingredient in the capsule and water delivered by the thermal conditioner into the receiving space to: prepare the beverage; and/or deliver the beverage via the beverage outlet arrangement.

The machine typically has a discharge arrangement configured to guide the beverage from the beverage collecting surface to a dispensing area configured to receive a user-receptacle for collecting such beverage from such machine. The dispensing area may be delimited by an outside upright machine face and/or a cup support.

The discharge arrangement may have an upstream part that is stationary relative to the cover when the holder and the cover are relatively moved between the open position and the closed position. The discharge arrangement can have a downstream part that is stationary relative to the holder when the holder and the cover are relatively moved between the open position and the closed position.

The discharge arrangement may have a tubular part. For example, the tubular part forms a or the above upstream part.

The discharge arrangement may include a downstream member. The member may be a downstream chamber for refining foam contained in the beverage e.g. by a refining arrangement such as one or more bubble dividers and/or a liquid diverting member that is configured to direct selectively the beverage to the dispensing area and waste liquid to a waste collector. For instance, the downstream member forms a or the above downstream part.

The discharge arrangement can include at least one part, such as a or the above downstream part that is removable by a user for cleaning and/or servicing.

The discharge arrangement can have a first part, such as a or the above upstream part, and a second part, such as a or the above downstream part. The second part can be mounted in or to a or the above outside housing that is stationary when the beverage is being prepared from the capsule in the receiving space. The first part can be mounted in or to a connection member connecting the cover to a guiding structure configured for enabling the holder and the cover to relatively move, e.g. pivotally and/or translationally, between their open and closed positions along the guiding structure, so that when the holder and the cover are in their closed position the first part projects into the outside housing and/or the second part projects into the connection member .

The discharge arrangement can include the configurations disclosed in PCT/EP18/085359,

PCT/EP18/ 085360 and PCT/EP18/ 085763.

The machine can be configured such that the beverage, when leaving the beverage collecting surface, and the water, when guided by the water inlet, have a temperature difference of less than 10°C, such as a difference of less than 7°C, e.g. of less than 4°C. For instance, the beverage collecting surface is positioned adjacent: an upstream water flow part in the thermal conditioner; a downstream water flow part in the thermal conditioner; or therebetween.

The thermal conditioner may include a thermoblock having a massive metal block forming the body of the thermal conditioner. For instance, the massive metal block extends about a central axis of the beverage processing unit such as a centrifugation axis.

The thermal conditioner may have a duct in the body of the thermal conditioner. Such duct may be configured to guide and thermally condition the water to be delivered into the inlet. The duct may form one or more peripheral loops, e.g. extending helicoidally about a or the central axis of the beverage processing unit, such as a centrifugation axis. The duct may extend substantially in parallel and/or adjacent to the beverage collecting surface .

The thermal conditioner can include a thermal generator. For instance, the thermal generator is a heat remover (as a coldness generator) , such as a thermocouple, and/or a heat generator, such as a resistive or inductive heater e.g. a discrete resistor and/or a thick film heater.

The thermal generator may form a peripheral loop extending about a or the above central axis of the beverage processing unit, such as a centrifugation axis. The thermal generator may form a structure extending substantially in parallel and/or adjacent to the beverage collecting surface.

The thermal generator can form an outside layer on the body of the thermal conditioner, such as an outside thick film resistor. The thermal generator may form an internal sunk component in the body of the thermal conditioner such as a discrete component, e.g. an electric resistor and/or induction heating path.

The machine may include a water source, such as a water tank, and an upstream water guide, e.g. a flexible guide, fluidically connected to the water source and to the thermal conditioner for guiding water from the source to the conditioner. For instance, the water guide is associated with a water driver, such as a pump, for driving water from the source to the conditioner via the guide. The guide may be made of one or more sections. The guide may also include or be associated with one or more functional parts, such as one or more of flowmeters, temperature sensors and pressure sensors.

The holder and the cover can be relatively movable, e.g. translationally and/or pivotally movable, between their open and closed positions along a guiding structure. The upstream water guide may pass at or by the guiding structure. For instance, the upstream water guide is secured by the guiding structure and a water guide support .
