Description:
Countertop Cooking Appliance

FIELD OF THE INVENTION

The present invention generally relates to food devices. More particularly, the present invention is a cheese-making countertop cooking appliance which includes a touch-screen display that allows the user to choose from various default recipes of cheese. Additionally, the present invention can be synced to a software application to share and receive custom recipes with other users.

BACKGROUND OF THE INVENTION

The human species could not have survived through winter without harnessing the preservative power of natural fermentation and enjoying the consequent nutritional improvements. Through processes that typically involve the addition and use of salts, acids, and temperature-controlled environments, vegetables, meats, and dairy products could develop into krauts, cured meats, and cheeses, each of which contains a wide array of probiotic benefits. Trends in mass food manufacturing, however, have borne the elimination of such methods due primarily to their reliance on complicated bacterial processes. While fermentation done properly is harmless and nutritionally beneficial, improper fermentation can lead to the development of various molds and bacteria that are dangerous for humans to consume. Therefore, mass-produced foods are now often developed with artificial preservatives, thus depriving the resultant foods of not only their beneficial probiotic benefits but also much of their flavor.

In response to the challenges presented by mass food production, social trends indicate a reversion to the old methods of fermentation, with a few modern

improvements. Sauerkrauts, kimchis, pickles, beers, and many other foods and drinks can be created by an individual with little expertise and a small amount of equipment.

Unfortunately, a simple process for making cheese at home consistently and safely remains elusive. Purchasing pre-made cheese means the user has no control in taste, freshness, or quality; however, with lack of a better option, this is often standard practice. Among the many challenges present in the cheese-making process, the maker has to worry about managing heat, adding appropriate amounts of ingredients, timing, draining whey, and, in many cases, applying constant pressure. Cheese-making devices are large and expensive, typically being designed for commercial as opposed to individual use. What is needed is a countertop device that can accept ingredients and instructions and can automatically deliver homemade cheeses. Further desirable is a device that provides a variety of cheese-making instructions for different cheeses.

The present invention addresses these issues. The present invention utilizes a touch-screen interface to allow the user to input instructions or select from a variety of existing recipes online. Additionally, the present invention can be synchronized with a software application to share and receive custom recipes with other users. The present invention includes a heating element for heating the ingredients of the cheese at appropriate times during the process. A specialized grid cutter is used to both mix ingredients during the liquid stages and to cut the curd in the later stages of the cheese making process. A pressing assembly can be added to allow the user to provide constant, even pressure to their cheese for the formation of hard cheeses. The present invention collects excess whey byproduct into a tank for disposal or subsequent processing by the user. Due to the controlled environment created by the present invention, the present invention can further be utilized for the creation of tofu, and even as a sous vide.

DETAILED DESCRIPTION OF THE INVENTION

All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

The present invention is a countertop cooking appliance that is used to manufacture food, particularly cheeses, with controlled heating, mixing, cutting, drainage, and pressure cycles. The present invention is also configured to accept various cooking patterns for different foods based on different recipes. The present invention comprises a curding chamber 1, a collecting receptacle 22, a structural base 23, a structural boom 24, a linearly and rotationally actuating (LRA) mechanism 25, a heater 45, a controller 46, and at least one interchangeable curd-interacting head 47. The curding chamber 1, shown in FIG. 1, is the space within which adding, mixing, cutting, heating, and otherwise interacting with components occurs. The collecting receptacle 22 is a basin that retains whey generated during the cheese-making process, as well as byproducts of other food-making processes. The structural base 23 provides the physical foundation for connecting components and allows for support of the present invention upon a countertop or other preferably flat surface. The structural boom 24 is a rigid extended segment that enables the application of appropriate motion during use of the present invention. The LRA mechanism 25 is a series of interconnected pieces that enable generation and translation of motion relative to the structural base 23 and the curding chamber 1. The heater 45 is a unit which regulates and maintains a target temperature during the food making process. The controller 46 is used to manage and process electronic inputs and convert such inputs into electronic outputs representing appropriate responses and commands for other components. The at least one interchangeable curd-interacting head 47 is a set of fixtures which provide various mixing, blending, cutting, pressing, and more capacities for use with the curding chamber 1.

The general configuration of the aforementioned components allows the present invention to efficiently and effectively create foods, especially cheeses, from basic ingredients and instructions. The curding chamber 1 is mounted offset from the structural base 23. The created space allows for addition of the collecting receptacle 22. The collecting receptacle 22 is positioned in between the curding chamber 1 and the structural base 23. Thus, acceleration due to gravity results in waste products falling into the collecting receptacle 22. The curding chamber 1 is in fluid communication with the collecting receptacle 22. This arrangement enables the collecting receptacle 22 to gather all food byproducts during food processing from the curding chamber 1 to the collecting receptacle 22. As shown in FIG. 2, the structural boom 24 is positioned offset from the curding chamber 1, opposite the collecting receptacle 22. In this way, the structural boom 24 is optimally positioned to interact with the curding chamber 1. The structural boom 24 is operatively mounted to the structural base 23 by the LRA mechanism 25, wherein the LRA mechanism 25 is used to drive linear and rotational movement of the structural boom 24 in relation to the structural base 23. Thus, the position of the structural boom 24 over the curding chamber 1 allows motion from the LRA mechanism 25 to affect the contents of the curding chamber 1. The at least one interchangeable curd-interacting head 47 is operatively mounted to the structural boom 24, wherein the structural boom 24 is used to slide the at least one interchangeable curd-interacting head 47 into and out of the curding chamber 1. Therefore, the motion generated by the LRA mechanism 25 and transmitted through the structural boom 24 results in the at least one interchangeable curd-interacting head 47 affecting the contents of the curding chamber 1. The heater 45 is in thermal communication with the curding chamber 1. In this arrangement, the heater 45 controls the amount of heat applied to the curding chamber 1. The controller 46 is electronically connected to the heater 45 and the LRA mechanism 25. Such an arrangement is advantageous in that the heater 45 can respond to different electronic outputs from the controller 46, resulting in precise control over the physical processing of contents of the curding chamber 1.

The LRA mechanism 25 must be capable of not only providing lifting and dropping motion to the structural boom 24, but also allowing the structural boom 24 and connected components to swivel away from the curding chamber 1, thus allowing the user to swap out the at least one interchangeable curd-interacting head 47. This allows the user to control interaction of the at least one interchangeable curd-interacting head 47 with the contents of the curding chamber 1. To achieve this, the LRA mechanism 25 comprises a first motor 26, a transmission 29, a cam mechanism 32, a structural platform 41, and a structural column 42. The first motor 26 is a power source that converts electrical power into rotational mechanical energy. The transmission 29 is a set of interconnected gears, pulleys, or other such rotating components capable of transferring power across the LRA mechanism 25. The cam mechanism 32 is utilized to convert rotational energy from the transmission 29 into linear motion. The structural platform 41 is used for the arrangement of the structural column 42, the transmission 29, and the first motor 26 in relation to each other. The structural column 42 is a preferably cylindrical post that elevates the structural platform 41 into a position from which the components arranged by the structural platform 41 may interact with the curding chamber 1. The first motor 26 comprises a first stator 27 and a first rotor 28. The first stator 27 is a stationary segment of the first motor 26 that allows for positioning of the first motor 26. The first rotor 28 is a rotating segment that inputs power into the transmission 29. The

transmission 29 comprises a power input 30 and a power output 31, as shown in FIG. 3. The power input 30 is a generally disc-shaped unit that receives a driving rotational motion from the first rotor 28. The power output 31 is a generally disc-shaped unit that sends the driving rotation motion to the cam mechanism 32. The cam mechanism 32 comprises a rotational input 33 and a linear output 34. The rotational input 33 allows the cam mechanism 32 to receive the driving rotational motion from the power output 31.

The linear output 34 is allows the cam mechanism 32 to output the driving rotational motion as a reciprocating linear motion. The structural column 42 comprises a first column end 43 and a second column end 44. The first column end 43 is the section of the structural column 42 which supports the LRA mechanism 25 onto the structural base 23. The second column end 44 is the section of the structural column 42 that enables motion of the LRA mechanism 25 relative to the structural column 42.

The structural column 42, structural platform 41, and structural boom 24 work in conjunction to arrange the LRA mechanism 25 appropriately relative to the curding chamber 1. The structural column 42 is positioned normal to the structural base 23. Thus, the structural column 42 provides optimal elevation of the cam mechanism 32 to the structural base 23. The first column end 43 is connected onto the structural base 23. The first column end 43 therefore positions the structural column 42 relative to the structural base 23. The cam mechanism 32 is laterally mounted to the structural column 42, adjacent to the second column end 44. Thus, the cam mechanism 32 is offset from the structural base 23 by the structural column 42. The structural platform 41 is laterally connected to the structural boom 24. The structural platform 41 is therefore able to move in conjunction with the structural boom 24. The first stator 27 is connected onto the structural platform 41. Such a connection ensures the first rotor 28 can operate relative to the structural platform 41. The first rotor 28 is torsionally connected to the power input 30. Thus, the power input 30 receives power from the first motor 26, enabling the power input 30 to rotate relative to the structural platform 41. The power output 31 is operatively coupled to the rotational input 33, wherein the power output 31 is used to actuate the rotational input 33. This connection results in the transfer of power from the first motor 26 to the rotational input 33. The structural boom 24 is positioned

perpendicular to the structural column 42. Thus, the structural boom 24 may extend over the curding chamber 1. The structural boom 24 is operatively mounted to the linear output 34, wherein the linear output 34 is used to move the structural boom 24 in an up- and-down motion. In this arrangement, the linear output 34 allows the structural boom 24, and therefore the connected at least one interchangeable curd-interacting head 47, to actuate into and out of the curding chamber 1.

The power output 31 and the power input 30 must work in conjunction to provide power from the first motor 26 to the rotational input 33. To this end, the power input 30 is preferably a first gear. Further, the power output 31 is preferably a second gear. As a pair of gears, as seen in FIG. 3, the power input 30 and the power output 31 are capable of efficiently transmitting and regulating power through the LRA mechanism 25. The first gear is rotatably mounted onto the structural platform 41. Thus, the first gear is free to rotate with the first rotor 28. The second gear is also rotatably mounted onto the structural platform 41. This allows the second gear to rotate freely relative to the structural platform

41. The first gear is engaged by the second gear. Thus, the second gear rotates in conjunction with the first rotor 28 through the first gear, optionally with an advantageous gear ratio to allow for control over rotational output speed. In an alternative embodiment, the power input 30 is a first pulley and the power output 31 is a second pulley. The first pulley and the second pulley are connected by a belt, thus enabling energy transmission 29 and control from the power input 30 to the power output 31.

The cam mechanism 32 must provide the capacity for the structural boom 24 to rise and fall. To this end, the cam mechanism 32 further comprises a tubular body 37 and at least one bearing 40. The linear output 34 is a male threading, which is a helical ridge that engages with the rotational input 33 to enable conversion of rotational motion into linear motion. Conversely, the rotational input 33 is a female threading, which is a helical cut as shown in FIG. 4 that engages with the male threading to enable conversion of rotational motion into linear motion. The tubular body 37 is a generally hollow cylindrical unit about which the male threading and the female threading interconnect. The at least one bearing 40 is a rotating body which enables freedom of rotational motion while preventing free translational motion. The tubular body 37 comprises an inner annular surface 38 and an outer annular surface 39. The inner annular surface 38 is the area upon which the female threading may be positioned. Conversely, the outer annular surface 39 is the area upon which the power output 31 may be joined. To properly arrange for interaction between the male threading and the female threading, the male threading is laterally connected around the structural column 42. Thus, the male threading is positioned to affect the female threading by creating force against the structural column

42. The male threading is positioned adjacent to the second column end 44. In this way, the male threading does not allow for the female threading to operate too close to the structural base 23. The female threading is connected onto the inner annular surface 38. By connecting the female threading in this way, the inner annular surface 38 can connect to the structural column 42 by the male threading. The female threading is engaged by the male threading. The rotation of the female threading against the male threading results in the up-and-down motion of the cam mechanism 32. The outer annular surface 39 is rotatably connected to the structural boom 24 by the at least one bearing 40. This connection allows the structural boom 24 to swing out of the way of the curding chamber 1 to allow for manipulation of the curding chamber 1 and the at least one interchangeable curd-interacting head 47 without interfering with the operation of the cam mechanism 32. The power output 31 is torsionally connected to the outer annular surface 39. Thus, the rotation of the power output 31 against the static structural column 42 results in up-and- down motion of the cam mechanism 32.

To properly agitate contents, the at least one interchangeable curd-interacting head 47 must be able to operate not only linearly to and from the curding chamber 1, but also twisting within the curding chamber 1. To achieve this, the present invention further comprises a second motor 53. As shown in FIG. 5, the second motor 53 is a power source that converts electrical power into rotational mechanical energy. The second motor 53 comprises a second stator 54 and a second rotor 55. The second stator 54 is a stationary segment of the second motor 53 that allows for positioning of the second motor 53. The second rotor 55 is a rotating segment that transmits energy to the at least one

interchangeable curd-interacting head 47. The second stator 54 is laterally mounted to the structural boom 24. In this way, the second motor 53 can rotate relative to the structural boom 24. The second stator 54 and the LRA mechanism 25 are positioned opposite to each other along the structural boom 24. Such an arrangement positions the second stator 54 appropriately above the curding chamber 1. The second rotor 55 is torsionally connected to the at least one interchangeable curd-interacting head 47. Thus, the at least one interchangeable curd-interacting head 47 rotates in accordance with the rotation of the second rotor 55. The controller 46 is electronically connected to the second motor 53. This connection enables the controller 46 to send appropriate commands to the second motor 53 to allow the second motor 53 to turn the at least one interchangeable curd interacting head 47 during processing steps.

The at least one interchangeable curd-interacting head 47 needs to be in position to affect the contents of the curding chamber 1. To do so, the present invention further comprises a hollow extension arm 56. As shown in FIG. 5, the hollow extension arm 56 is a rigid segment that extends to better position the at least one interchangeable curd interacting head 47. The hollow extension arm 56 is laterally connected to the structural boom 24. In this way, the hollow extension arm 56 moves with the structural boom 24 in accordance with the LRA mechanism 25. The hollow extension arm 56 is oriented towards the curding chamber 1. Thus, the hollow extension arm 56 improves the ability of the structural boom 24 to affect the motion of the at least one interchangeable curd interacting head 47. The second motor 53 is mounted within the hollow extension arm 56. Therefore, the second motor 53 is optimally positioned to enable rotating motion of the at least one interchangeable curd-interacting head 47.

The curding chamber 1 may utilize a variety of different mechanisms and arrangements to achieve the goal of appropriately moderating temperature and agitation of inserted contents. In one such mechanism, the curding chamber 1 comprises an annular lid 2, a first receptacle 3, and a second receptacle 4. The annular lid 2 is a generally ring- shaped protector that retains the contents of the curding chamber 1. The first receptacle 3 is a container that is used to receive and contain various ingredient inputs. The second receptacle 4 is a container that interacts with the first receptacle 3 to enable appropriate control over drainage and fluid flow through the first receptacle 3. The first receptacle 3 and the second receptacle 4 each comprises a lateral wall 5, a plurality of lateral perforations 6, a base plate 7, and a plurality of base perforations 8, as seen in FIG. 5.

The lateral wall 5 is a rigid, generally annular structure that prevents undesirable loss of the contents within the curding chamber 1 through the sides of the first receptacle 3 and the second receptacle 4. The plurality of lateral perforations 6 is a set of openings through which fluids may flow into or out of the first receptacle 3 and the second receptacle 4.

The base plate 7 is a retaining surface that prevents undesirable loss of the contents of the curding chamber 1 through the bottom of the first receptacle 3 and the second receptacle 4 due to gravity. The plurality of base perforations 8 is a set of openings through which fluids may flow into or out of the first receptacle 3 and the second receptacle 4. The first receptacle is positioned within the second receptacle 4. Thus, the fluids within the first receptacle 3 are also retained by the second receptacle 4. The lateral wall 5 is

perimetrically connected to the base plate 7. This arrangement prevents the loss of fluids from between the base plate 7 and the lateral wall 5. The plurality of lateral perforations 6 traverses through the lateral wall 5. Furthermore, the plurality of lateral perforations 6 is distributed about the lateral wall 5. Such an arrangement enables even flow of fluid through the plurality of lateral perforations 6. The plurality of base perforations 8 traverses through the base plate 7. Furthermore, the plurality of base perforations 8 is distributed across the base plate 7. This arrangement also improves flow consistency during various processing steps. The annular lid 2 is hermetically connected across the lateral wall 5 of the first receptacle 3, opposite the base plate 7 of the first receptacle 3. Thus, the annular lid 2 prevents loss of the contents through the first receptacle 3 during food processing.

The above arrangement of the curding chamber 1 operates between two configurations. One such configuration is a churning configuration, in which the curding chamber 1 manipulates all of the contents of the first receptacle 3 together. In the churning configuration, the base plate 7 for the first receptacle 3 is pressed against the base plate 7 of the second receptacle 4. There is therefore no space for fluid flow between the base plate 7 for the first receptacle 3 and the base plate 7 for the second receptacle 4. Each of the plurality of base perforations 8 of the first receptacle 3 is hermetically sealed by a corresponding section of the base plate 7 of the second receptacle 4. Further, each of the plurality of base perforations 8 of the second receptacle 4 is hermetically sealed by a corresponding section of the base plate 7 of the first receptacle 3. Thus, fluid cannot flow from the base plate 7 of the first receptacle 3 through the base plate 7 of the second receptacle 4. Each of the plurality of lateral perforations 6 of the first receptacle 3 is hermetically sealed by a corresponding section of the lateral wall 5 of the second receptacle 4. Further, each of the plurality of lateral perforations 6 of the second receptacle 4 is hermetically sealed by a corresponding section of the lateral wall 5 of the first receptacle 3. In this way, fluids cannot pass from the lateral wall 5 of the first receptacle 3 through the lateral wall 5 of the second receptacle 4.

The other relevant configuration of the curding chamber 1 in this embodiment is a draining configuration, in which fluid is allowed to drain through both the first receptacle 3 and the second receptacle 4. In the draining configuration, the annular lid 2 is engaged by the at least one interchangeable curd-interacting head 47. Thus, the annular lid 2 and, consequently, the hermetically connected first receptacle 3 may actuate and rotate in accordance with the LRA mechanism 25 and the second motor 53. The annular lid 2 is engaged by the at least one interchangeable curd-interacting head 47. The engagement of the at least one interchangeable curd-interacting head 47 allows the first receptacle 3 to be lifted off the second receptacle 4 by operating the annular lid 2. The base plate 7 for the first receptacle 3 is positioned offset from the base plate 7 of the second receptacle 4. This offset enables fluid to flow through the plurality of base perforations 8 of the first receptacle 3, onto the base plate 7 of the second receptacle 4, and subsequently, through the plurality of base perforations 8 of the second receptacle 4. The plurality of base perforations 8 of the first receptacle 3 is in fluid communication with the plurality of base perforations 8 of the second receptacle 4. In this way, fluid flows through both the plurality of base perforations 8 of the first receptacle 3 and the plurality of base perforations 8 of the second receptacle 4. Each of the plurality of lateral perforations 6 of the first receptacle 3 is in fluid communication with a corresponding perforation from the plurality of lateral perforations 6 of the second receptacle 4. In this way, fluid flows through both the plurality of lateral perforations 6 of the first receptacle 3 and the plurality of lateral perforations 6 of the second receptacle 4.

The curding chamber 1 may utilize a different mechanism in order to effectively process foods. In another such mechanism, the curding chamber 1 comprises a thermally- conductive pot 9, a drain valve 12, a strainer 13, and an annular bracket 14, as shown in FIG. 7. The thermally-conductive pot 9 is a heat-transferring container that holds inserted ingredients. The drain valve 12 is a connected opening that toggles to selectively allow fluids and substances to flow. In an exemplary embodiment, the drain valve 12 is a sliding valve with a panel that slides into or out of a sleeve to increase or decrease flow through the drain valve 12. The strainer 13 is a mesh container that collects solids or semi-solids while separating liquids. The annular bracket 14 is a generally ring-shaped mounting device. The thermally-conductive pot 9 comprises a lateral pot portion 10 and a base pot portion 11. The lateral pot portion 10 is a curved surface that retains the contents of the thermally-conductive pot 9. The base pot portion 11 is a generally flat segment of the thermally-conductive pot 9 that prevents the contents of the thermally-conductive pot 9 from exiting due to gravity. The lateral pot portion 10 is perimetrically connected around the base pot portion 11. Such an arrangement ensures that the contents are retained within the thermally-conductive pot 9. The drain valve 12 is integrated into the base pot portion 11. Thus, the drain valve 12 provides the only exit for the contents of the thermally-conductive pot 9 during processing. The thermally-conductive pot 9 is in fluid communication with the strainer 13 through the drain valve 12. This arrangement allows processed foods, such as cheese curds and residual whey from processing, to separate within the strainer 13 after passing through the drain valve 12. The thermally-conductive pot 9 is situated upon the strainer 13 by the annular bracket 14. Thus, the annular bracket 14 secures the strainer 13 in position during use. This embodiment of the curding chamber 1 allows for the mixing, heating, and agitating processes to occur in the thermally-conductive pot 9, then the drain valve 12 to open, thus allowing for selective collection of curds and removal of whey, and then an optional pressing step to occur within the strainer 13.

Another mechanism of the curding chamber 1 denotes an alternative mechanism for operating the valve through which food contents may traverse. In this mechanism, the curding chamber 1 comprises a curd container 15 and a press valve 19, as seen in FIG. 7. The curd container 15 is a space in which primary mixing and agitation takes place. The press valve 19 is an operable cover 57 that is biased, by either springs or by other configuration, towards the curd container 15. The curd container 15 comprises a lateral container portion 16, a base container portion 17, and a plurality of drain holes 18. The lateral container portion 16 is a generally smooth wall or surface which contains ingredients and byproducts during early processing steps. The base container portion 17 is the segment of the curd container 15 that prevents undesirable losses due to gravity. The base container portion 17 may be lofted or angled in order to better arrange the press valve 19. The plurality of drain holes 18 is a series of openings through which fluids may exit the curd container 15. Furthermore, the lateral container portion 16 is perimetrically connected around the base container portion 17. This arrangement prevents undesirable loss of contents of the curd container 15. The plurality of drain holes 18 traverses through the base container portion 17. Further, the plurality of drain holes 18 is distributed across the base container portion 17. Thus, collected ingredients may exit only through the plurality of drain holes 18 at the appropriate point of processing. The press valve 19 is operatively mounted to the base container portion 17, wherein the at least one interchangeable curd-interacting head 47 is used to actuate the press valve 19 in order to open the plurality of drain holes 18. Thus, the at least one interchangeable curd interacting head 47 controls the drain valve 12 and, consequently, the flow of contents from the curd container 15.

In a further embodiment, the user may desire to create a less viscous final result, such as yogurt. To achieve this using the above mechanism, the curding chamber 1 further comprises a framed sieve 20. The framed sieve 20, as seen in FIG. 7, is a sifter of a desirable mesh grade or hole diameter which prevents the escape of more low viscosity fluids. The framed sieve 20 is positioned within the curd container 15. In this way, the framed sieve 20 is capable of interacting with ingredients before they pass through the plurality of drain holes 18. The framed sieve 20 is situated upon the base container portion 17. Thus, all food material must pass through the framed sieve 20 in order to exit the curd container 15.

The present invention must interact with liquids and gelatinous solids in order to be effective at developing cheese and tofu. Correspondingly, the at least one

interchangeable curd-interacting head 47 comprises a mixing cutter 48. The mixing cutter 48 is a set of blades that can attach to the present invention. The mixing cutter 48 comprises a plurality of first blades 49 and a plurality of second blades 50, as shown in FIG. 10 and 11. The plurality of first blades 49 and the plurality of second blades 50 are two sets of sharp-edged cutting tools. The plurality of first blades 49 is positioned perpendicular to the plurality of second blades 50. Further, the plurality of first blades 49 and the plurality of second blades 50 are arranged in a grid configuration. This arrangement is optimal for cutting through thick cheese curds that form. In an exemplary embodiment, each of the plurality of first blades 49 is positioned at a first acute angle 66 with a central axis 65 of the second receptacle 4. Similarly, each of the plurality of second blades 50 is positioned at a second acute angle 67 with the central axis 65 of the second receptacle 4. This arrangement enables the purely linear motion of the at least one interchangeable curd-interacting head 47 to produce desirable waves and turbulence in liquid mixtures. In another exemplary embodiment, a mixing cutter 48 comprises a plurality of wires rather than a plurality of first blades 49 and a plurality of second blades 50. Such an arrangement ensures that contents of the curding chamber 1 are effectively cut, chopped, or agitated.

In another arrangement, the user may wish to blend components together. To achieve this, the at least one interchangeable curd-interacting head 47 comprises a planar cutter 51 and a chamber lid 68. The planar cutter 51, as represented in FIG. 12, is a device which provides desirable agitation of contents of the curding chamber 1. The chamber lid 68 is a retaining device which prevents ingredients from spilling out of the curding chamber 1 during use. The planar cutter 51 is positioned parallel to a central axis 65 of the curding chamber 1. This arrangement allows the planar cutter 51 to equally affect all areas of the curding chamber 1. The chamber lid 68 is mounted across a primary opening 21 of the curding chamber 1. In this way, the chamber lid 68 is positioned to prevent spillage or undesirable fluid flow. The planar cutter 51 is rotatably integrated into the chamber lid 68. Thus, the chamber lid 68 orients and controls the rotation of the planar cutter 51. The planar cutter 51 comprises a plurality of first wires 69 and a plurality of second wires 70. The plurality of first wires 69 is a series of generally thin extrusions extending equidistant from each other. Similarly, the plurality of second wires 70 is a series of generally thin extrusions extending equidistant from each other. The plurality of first wires 69 is positioned perpendicular to the plurality of second wires 70. Thus, the plurality of first wires 69 and the plurality of second wires 70 affect the contents of the curding chamber 1 in a grid pattern, thereby efficiently releasing excess whey contained throughout the curd. The plurality of first wires 69 is positioned adjacent to the central axis 65 of the curding chamber 1. Similarly, the plurality of second wires 70 is positioned adjacent to central axis 65 of the curding chamber 1, opposite the plurality of first wires 69. This arrangement allows the plurality of first wires 69 and the plurality of second wires 70 to chop through and otherwise agitate the contents of the curding chamber 1. Furthermore, the at least one interchangeable curd- interacting head 47 further comprises a mixing blade 71 and a selective rotation mechanism 72. The mixing blade 71 is a sharpened cutter that is angled to provide appropriate agitation of the contents of the curding chamber 1. The selective rotation mechanism 72 is a series of rotating components that allows the mixing blade 71 to rotate when the second motor 53 spins in one direction. The mixing blade 71 is rotatably connected to the planar cutter 51, opposite the chamber lid 68. This arrangement allows the present invention to both mix and cut through the contents of the curding chamber 1. The planar cutter 51 and the mixing blade 71 are operatively coupled to the structural boom 24 by the selective rotation mechanism 72, wherein the selective rotation mechanism 72 rotates the planar cutter 51 in a first direction while holding the mixing blade 71 at rest, and wherein the selective rotation mechanism 72 holds the planar cutter 51 at rest while rotating the mixing blade 71 in a second direction, and wherein the first direction and the second direction are opposite rotational directions. Thus, the selective rotation mechanism 72 allows for rotation of the planar cutter 51 in one direction and the mixing blade 71 in the other direction.

In order to properly pressurize cheeses, the at least one interchangeable curd interacting head 47 comprises a press 52, as shown in FIG. 9. The press 52 is a generally flat surface optimized for providing pressure upon the contents of the curding chamber 1. The press 52 is positioned normal to a central axis 65 of the curding chamber 1. This arrangement ensures the press 52 is adequately arranged for the application of downward force upon the contents of the curding chamber 1. Such pressure is particularly desirable during the production of hard cheeses, as opposed to softer cheeses.

The present invention requires a segment that protects the components proximal to and including the structural boom 24. To this end, the present invention comprises a cover 57, as shown in FIG. 1. The cover 57 is a rigid extrusion that provides protection for the various components of the present invention. The curding chamber 1 comprises a primary opening 21. The primary opening 21 is the space through which food and ingredients may enter the curding chamber 1. The structural boom 24, the linear actuator, the at least one interchangeable curd-interacting head 47, and the primary opening 21 are housed by the cover 57. Thus, the cover 57 prevents contaminants, projectiles, or other stray elements from interfering with the operation of the present invention.

The user requires a means of interacting with the present invention. To this end, the present invention comprises a user-interfacing panel 58, as seen in FIG. 1. The user interfacing panel 58 is a touchscreen surface that provides options, including pre-set recipes as well as custom controls for applying heat, pressure, time, and agitation to the contained mixture. The user-interfacing panel 58 is mounted onto the structural base 23. This arrangement provides a convenient location for inputting instructions and monitoring progress. The user-interfacing panel 58 is electronically connected to the controller 46. In this way, instructions from the user-interfacing panel 58 transfer to the controller 46, and consequently, throughout the present invention. Moreover, the present invention further comprises a wireless communication module 59 and an external computing device 60. The wireless communication module 59 is a device that provides internet connectivity for the present invention. The external computing device 60 can be, but is not limited to, a smartphone, a desktop computer, a laptop computer, or a tablet personal computer with a corresponding application that enables users to interact with the present invention, as well as with each other. The wireless communication module 59 is mounted onto the structural base 23. Furthermore, the wireless communication module 59 is electronically connected to the controller 46. In this way, the controller 46 is equipped to send and receive signals directing the present invention. The wireless communication module 59 is communicably coupled to the external computing device 60. This arrangement results in progress updates being provided to the user, and the user remotely providing instruction to the present invention.

A wide array of sensors may be utilized in order to provide the controller 46 with feedback regarding the status of food preparation. To this end, the present invention comprises a temperature sensor 61, as seen in FIG. 8. The temperature sensor 61 is an electronic device capable of capturing data regarding thermal energy and converting that data into corresponding electrical signals. The temperature sensor 61 is in thermal communication with the curding chamber 1. This arrangement allows the temperature sensor 61 to read the temperature of the curding chamber 1. The temperature sensor 61 is electronically connected to the controller 46. This arrangement enables the temperature sensor 61 to relay collected data to the controller 46. In addition, the present invention further comprises a pressure sensor 62. The pressure sensor 62 is an electronic device capable of capturing data regarding mechanical pressure and converting that data into corresponding electrical signals. The pressure sensor 62 is pressed in between the curding chamber 1 and the structural base 23. This positioning allows the pressure sensor 62 to capture data regarding the weight of items within the curding chamber 1. The pressure sensor 62 is electronically connected to the controller 46. This arrangement enables the pressure sensor 62 to relay collected data to the controller 46. Furthermore, the present invention further comprises a magnet 63 and a Hall-effect sensor 64. The magnet 63 is a metal unit that emits a magnetic field. The Hall-effect sensor 64 is a device capable of measuring distance from a magnet 63 through the magnetic field generated by that magnet 63. The magnet 63 is integrated into the at least one interchangeable curd- interacting head 47. Correspondingly, the Hall-effect sensor 64 is mounted in between the curding chamber 1 and the structural base 23. In this way, the magnet 63 and the Hall- effect sensor 64 are positioned appropriately to measure the distance between the at least one interchangeable curd-interacting head 47 and the bottom of the curding chamber 1. The Hall-effect sensor 64 is electronically connected to the controller 46. This arrangement enables the Hall-effect sensor 64 to relay collected data to the controller 46.

Although the invention has been explained in relation to its preferred

embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
