Description

Technical Field

[0001] This application relates to a corn separator and a food grinder. More specifically, this application relates to an electric corn separator capable of processing young corn cobs, obtaining corn puree by directly grinding the corn kernels on the cob. The machine can also be used to grind various types of food, including but not limited to some roots and vegetables.

[0002] Related Applications

[0003] This application claims the benefit of U.S. Non - Provisional Application No. 17 / 991,769, filed on November 21, 2022, and U.S. Provisional Application 63 / 308,970, filed on February 11, 2022. Background Art

[0004] Corn is consumed in many countries and regions of the world. The recipes are diverse and require processing corn in various ways. Many recipes call for puree made from still - young corn kernels. There are several ways to obtain such corn puree. One way to accomplish this is to hold the corn cob in one hand and repeatedly rub it against a grinder, or hold the corn cob steady while rubbing it against the grinder. These methods are very labor - intensive and often result in finger injuries because the hand can easily slip off the corn cob, rubbing the hand or fingers directly against the grinder, or the grinder can slip across the fingers holding the corn cob. For these reasons, these methods cannot be used by those who no longer have the dexterity and physical strength to perform this task.

[0005] Another method is to separate the corn kernels from the cob and then grind the corn kernels in an electric or manual grain mill. Special - designed knives or other hand tools can be used to cut the corn kernels from the cob. In all cases, the person performing this task must use sharp tools. This step can be dangerous as it can result in hand injuries. This method also has other drawbacks. For example, when cutting the corn kernels from the cob, the cutting distance of the corn kernels relative to the cob may not be ideal. In some cases, the corn kernels may be cut too far from the cob, resulting in parts of the corn kernels remaining on the cob that will be discarded; and in other cases, the cut may be too close to the cob, resulting in too much chaff being carried away with the corn kernels, making the corn puree have an unwanted grassy texture. Once the corn kernels are separated from the cob, they need to be ground in a grain mill. This is the second equally labor - intensive step required to obtain corn puree in this method.

[0006] The complexity of all these methods and the inherent danger of physical injury make it difficult or undesirable for many people to prepare foods that require corn puree made from young corn cobs.

[0007] Other machines have been designed to perform this task; however, all of these machines have considerable disadvantages. In some cases, the obtained corn puree is very coarse, with large chunks or even whole kernels of corn mixed in the puree, and the final products from these machines also need to be processed by a grain mill to obtain the desired puree consistency. In other cases, the existing machines are large and thus not suitable for home use. In particular, it is impractical to place one of these large machines on the countertop of a home kitchen or similar space.

[0008] Considering all of the above factors, there is a need for a machine that can process young corn cobs to safely obtain puree with minimal effort from the user in a single step, while the machine is small enough and easy to operate to be considered a small kitchen appliance, such that any adult can place and operate it on a regular kitchen worktop or similar space. Summary of the Utility Model

[0009] This application includes a novel electric corn separator and food grinder (“machine”) designed to process young corn cobs, producing corn puree by directly grinding the corn kernels on the cob. The machine can also be used to grind various types of products, including but not limited to some roots and vegetables.

[0010] In a preferred embodiment of this application, the machine is designed and constructed to be used as a small kitchen appliance, but alternative embodiments may be more suitable for industrial applications. In the specific embodiment described herein, the machine consists of multiple modules assembled with each other.

[0011] The bottom module (“motor base”) houses an electric motor with a coupler that provides rotational motion to the rest of the machine. The main body of the machine (“main body”) is located on top of the motor base and has a coupler to receive the rotational motion transmitted by the motor base. The main body also includes a shaft and two gears to transmit the rotational motion to the grinder (“conical grinder”), which grinds the corn cob by rotating around it when the operator pushes the corn cob into the machine.

[0012] The conical grinder consists of several elements, including blades that adapt to the geometry of the corn cob as it passes through the central circular opening of the conical grinder. The conical grinder is contained within a cylindrical part (“centrifuge”) that is attached to the main body of the machine and works as a centrifuge mechanism together with the conical grinder. The centrifuge body also has a discharge channel through which the corn puree or other ground products come out of the machine.

[0013] The corn cobs are fed into the conical grater through a pipe, which is part of another module ("funnel") attached to the centrifuge. There are two rollers ("input rollers") between the end of the pipe and the conical grater, which prevent the corn cobs from rotating as they pass through the conical grater. In the main body, there is a second set of two rollers ("output rollers") after the conical grater, which prevent the naked corn cobs from rotating when they start to come out of the conical grater and before the corn cobs are completely out of the input rollers.

[0014] The corn cobs are inserted by hand into the funnel and then pushed in with a manual pusher ("Corn Baton"). The Corn Baton causes the corn cobs to be pushed until the naked corn cobs are completely out of the machine.

[0015] To grind vegetables or other products, the conical grater is replaced by a different grater ("FlatGrater"), and a sleeve ("funnel sleeve") is inserted into the funnel. The funnel sleeve keeps the input rollers apart, creating an unobstructed passage between the entrance of the funnel and the FlatGrater blades. To push the vegetables or other products to be ground, a different manual pusher ("FlatGrater Baton") is used. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] New electric corn separators and food grinders, devices, and methods for grinding corn or other suitable foods are discussed herein. For purposes of explanation, numerous specific details are set forth in the following description in order to provide a thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced without these specific details.

[0069] This disclosure is considered exemplary of the present application and is not intended to limit the present application to the specific embodiments described by the following figures or the specification.

[0070] The present application is now described by reference to the drawings representing the preferred embodiments. The figures depict modules, components, and features. A module may consist of one or more components to perform one or more functions. A component refers to a separate object that cannot be divided into other objects, or a component that will be regarded as a single object within the scope of this specification. A feature refers to the physical characteristics of a component.

[0071] In the specific embodiments described herein, the electric corn separator and the food grinder consist of various modules that can be easily attached and detached for cleaning and storage after each use. Each module works in cooperation with other modules to perform a predetermined task, whether it is to produce corn puree from fresh corn cobs or to grind vegetables or other suitable products.

[0072] Figure 1 An exemplary perspective view of the fully assembled electric corn separator and food grinder plus additional accessories according to some embodiments of the present application is depicted.

[0073] Figure 2 A disassembled perspective view of the machine indicating the modules including this specific embodiment is depicted. Module 100 is the motor base module. This module houses an electric motor (103, Figure 3 ) that provides rotational motion to the rest of the machine. In this specific embodiment, the motor base module (100, Figure 2 ) has a geometry that allows the body (200, Figure 2 ) to be attached to it by sliding the body (200) over the motor base.

[0074] Figure 3 An exemplary disassembled perspective view of the motor base module (100) showing its various main components is shown. The internal wiring harness is not shown, but the electrical connections are described herein. In this specific embodiment, the components include a motor base cover (102, Figure 3 ) that is fixed to the motor base housing (101, Figure 3 ) using four screws (110, Figure 3 ). The motor base (100) includes anti-slip pads (107, Figure 3)。These anti-slip pads (107) can be fixed to the motor base cover (102) or to the motor base housing (101). In this particular embodiment, the anti-slip pads (107) are inserted into slots on the bottom surface of the motor base cover (102), but in other embodiments, they can be fixed in place by other methods, all of which are within the scope of this application. The anti-slip pads (107) can be made of any suitable high-friction material (including but not limited to rubber) to prevent the machine from sliding during operation. The motor base cover (102) also has ventilation openings (102A, Figure 3 ), to provide air circulation for cooling the motor (103). The openings facilitate the circulation and distribution of air inside and outside the motor base module (100) to enhance the cooling of the motor (103). Figure 3 The possible distribution of these openings is shown. The motor base housing (101) and the motor base cover (102) can be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials.

[0075] The motor base module (100) includes a power cord (109, Figure 3 ), the end of which is a power plug. In the particular embodiment described herein, a power plug consistent with a specific power plug standard is shown, but other embodiments of this application can use different types of power plugs. The power cord (109) must be made of a wire gauge large enough to carry the current consumed by the motor (103) during long-term operation without overheating.

[0076] The motor base module (100) includes a power switch (108, Figure 3 ) that allows the machine to be turned on and off. A wire harness is installed inside the motor base module (100), and the wire harness carries line conductors from the power cord (109) to the power switch (108) and from the power switch (108) to one of the two connection points of the motor (103). The neutral cable can be directly connected from the power cord (109) to the second motor (103) connection point. The power switch (108) must be based on the current consumption rating of the motor (103).

[0077] For the proper operation of the machine, the motor (103) must provide sufficient torque and speed. To this end, if connected to a rotational speed reduction mechanism, a motor (103) with a higher speed and lower torque can be used. In Figure 3 the particular embodiment described, the motor (103) shaft is connected to a planetary gear reducer (104, Figure 3), but other speed reduction mechanisms can be used. The design and gear ratio of the rotational speed reduction mechanism depend on the shape and specifications of the motor (103). In other embodiments of this application, the motor (103) and the rotational speed reduction mechanism can be constructed as a single unit. The internal structure of the motor base housing (101) must be adapted to accommodate the specific shape and dimensions of the motor (103) and the speed reduction mechanism (if any). Figure 3 Describe the general distribution of the motor (103) and the planetary gear reducer (104) to provide a general understanding of a possible configuration. Many variations of this configuration can be implemented, all resulting in providing rotational motion at the speed and torque required for proper operation of the machine to the output coupler (106, Figure 3 )

[0078] The output coupler (106) has a shape that enables it to engage with a mating coupler in the main body module (200) and transfers motion from one module to another. At the same time, when the main body module (200) slides into position and attaches to the motor base module (100), these couplers are shaped in such a way that the two couplers rotate and align themselves with the mating couplers in the other module. These two functions can be achieved by using different coupler shapes. Figure 4 Describe a possible embodiment of this component. The output coupler (106) can be made of aluminum, metal alloy, hard plastic, or other suitable materials.

[0079] The output coupler (106) is directly connected to the motor (103) or the rotational speed reduction mechanism, depending on the specific configuration used. In this particular embodiment, the output coupler is connected to the planetary gearbox (104) via a connecting shaft (105, Figure 3 ) and the planetary gearbox (104) is connected to the motor (103) shaft.

[0080] Figure 2 The module 200 in represents an example of the main body module. In this particular embodiment, this module is located on top of the motor base module (100) and slides into position using mating shapes in a fixed position without a locking mechanism. The main body module (200) must be pulled upwards with very little force to remove it from the motor base (100). Figure 5 Shows an exploded perspective view of this module in this particular embodiment. The main body module (200) has an input coupler (203, Figure 5 ), and the input coupler is connected to the output coupler (106) of the motor base module (100). The input coupler (203) has similar characteristics to those of the output coupler (106) described in the previous paragraphs herein.

[0081] The input coupler (203) is attached to transfer rotational motion to a connection to the grinder base (210, Figure 5) spur gears (205, Figure 5 ) shafts (206, Figure 5 ). The input coupler (203) and the spur gears (205) can be made of metal alloy, hard plastic, or other materials suitable for high-speed gears. In a preferred embodiment, the shaft (206) can be made of stainless steel or a similar material and rotates within a bushing (207, Figure 5 ), and the bushing can be made of low-friction brass or a similar low-friction material.

[0082] In this particular embodiment, the main body module (200) has a detachable cover (202, Figure 5 ) that snaps into place and can be easily removed by pulling it from the knob (202A, Figure 6 ). This detachable cover (202) facilitates cleaning the interior of the main body module (200) after each use. The detachable cover (202) has two hinge portions (202B, Figure 6 ) that facilitate its installation and removal. In addition, the detachable cover (202) has a circular opening ("exit channel", 202C, Figure 6 ) that allows the naked corn cob to come out of the main body module (200). The detachable cover (202) can be made of plastic or other suitable materials that provide a certain degree of flexibility, which is necessary for the installation of the detachable cover and its removal from the main body housing (201, Figure 5 ).

[0083] An example of an embodiment of the grater base (210) is described in detail in FIG. 7. The grater base incorporates a spur gear (210A, Figure 7B ), a ball bearing seat (210B, Figure 7B ) and a coupling mechanism to attach a conical grater module (400, Figure 2 ) or a flat grater module (800, Figure 2 ) ("grater" module) to it. The coupling mechanism can be implemented in different ways. In this particular embodiment, the mechanism allows the grater module (400 or 800) to be attached with a small clockwise torque. During the assembly of this particular embodiment, four flexible tabs (210C, Figure 7A ) incorporated in the grater base (210) are slightly bent to allow four rigid tabs (401A, Figure 16B ) located on the bottom surface of the grater modules (400 and 800) to slide under the four flexible tabs (210C). When fully inserted, the tongue (210E, Figure 25 ) and the slot (401H, Figure 25) The connection is made by joining each of the four flexible tags (210C) to its corresponding rigid tag (401A), straightening the four flexible tags (210C) and ensuring the connection between the grater base (210) and the grater module (400 or 800). To remove the grater module (400 or 800) from the grater base (210), a small counterclockwise torque must be applied to the grater module (400 or 800). Figure 25 An example of a fully engaged tongue (210E) and groove (401H) connection is shown.

[0084] In this particular embodiment, the grater base (210) has four ramps ("grater base ramps" 210D, Figure 7A ), which work in concert with four ramps ("grater ramps" 401B, Figure 16B ) on the bottom surface of the grater module (400 or 800) to push the grater module (400 or 800) away from the grater base (210) when the grater module (400 or 800) is rotated counterclockwise. This feature facilitates the removal of the grater module (400 or 800) from the main body module (200). The grater base (210) can be made of metal alloy, hard plastic, or other materials suitable for high-speed gears, while these materials provide some degree of flexibility to the four flexible tags (210C). The naked corn cob passes through the central circular opening of the grater base (210) after leaving the conical grater module (400).

[0085] In this particular embodiment, the grater base (210) is connected to the top cover ("top cover" 218, Figure 5 ) of the main body housing by a ball bearing (209, Figure 9 ), but other attachment members that allow the grater base (210) to rotate can be used, all of which are within the scope of this application. The ball bearing housing (210B) of the grater base (210) is mounted on the outer ring of the ball bearing (209), and the inner ring of the ball bearing (209) is mounted in a cylindrical socket ("socket" 218C, Figure 5 ) on the top cover (218). The ball bearing (209) must have a large enough inner diameter for the naked corn cob to pass through it, and the ball bearing is made of stainless steel to prevent corrosion.

[0086] In this particular embodiment, the main body housing (201) has a fixed cover ("rear cover", 217, Figure 10 ) that is screwed in place. In other embodiments of this application, the rear cover (217) can be fixed in place by other members or integrated with the main body housing (201) as a single piece. The rear cover (217) and the main body housing (201) can be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials.

[0087] In this particular embodiment, the main body module (200) includes an output roller, also referred to as the "cob contact point" (212, Figure 5 ), which is located below the socket (218C, Figure 5 ). The purpose of the output roller (212) is to prevent the ear of corn from rotating when it leaves the conical grinder module (400) and is no longer in contact with the input roller (also referred to as the "corn contact point", Figure 13B 601 in), and at the same time the output roller (212) keeps the ear of corn aligned with the conical grinder module (400) until the naked cob completely exits the machine.

[0088] The corn contact point (601) and the cob contact point (212) are any of a rolling blade ( Figure 33A ), a rolling gear ( Figure 33B ), a rolling rack ( Figure 33C ), or a sliding blade ( Figure 33D ), all of which are within the scope of this application.

[0089] In this particular embodiment, the output roller (212) is encapsulated within an output roller housing (211, Figure 5 ), and the housing is attached to the rear of the top cover (218) by screws. In other embodiments, the output roller housing (211) can be attached to the top cover (218) by other means, or integrated with the top cover (218) as a single piece.

[0090] In this particular embodiment, the output roller (212) consists of two parallel rollers that can rotate independently. Each roller is composed of a plurality of parallel circular blades, the blades having a smaller diameter at the center of the roller and a gradually increasing diameter towards the edge of the roller. The output roller (212) is pulled towards each other by two tension springs (214, Figure 8 ). The minimum distance between the output rollers (212) is sufficient to allow them to grip a relatively thin naked cob. When a thicker naked cob passes through between them, the output rollers (212) can move apart from each other, and due to the force exerted by pulling the output rollers (212) towards each other through the tension springs (214), the output rollers (212) always hold the naked cob.

[0091] Each output roller (212) has a cylindrical opening throughout its length and each output roller is loosely mounted on axles (213, Figure 8 ) that extend side - by - side in the output roller housing (211). The two axles (213) have circular grooves to fix them in place using retaining rings (216, Figure 8 ) on each side. A spacer (215, Figure 8)To reduce friction. The axles (213) slide through slots created on the sides of the output drum housing (211) to allow the output drums (212) to move closer to and farther from each other. A tension spring (214) is connected to the ends of the axles (213). This connection can be made in a variety of ways. Figure 8 Depicts an embodiment in which each end of the tension spring (214) is in a hook at each end of its end. These hooks are connected to the axles (213) through holes machined near the edges of each axle (213).

[0092] The output drum housing (211) and the drums (212) can be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials. The axles (213) and the spacers (215) can be made of low-friction materials, including metal alloy, hard plastic, or other suitable food-grade materials. The positioning rings (216) can be made of metal alloy, hard plastic, or other suitable food-grade materials. In a preferred embodiment, the tension spring (214) is made of stainless steel.

[0093] In this particular embodiment, the top cover (218) has a built-in splash guard (218A, Figure 9 ) to prevent splashing of the corn paste or other ground products that may escape from the centrifugal module (300, Figure 2 ) during operation. Any splashing is contained in this way between the top cover (218) and the centrifugal module (300). The splashed material flows by gravity to the front lower part of the top cover (218), where there is an opening to drain any liquid residue into the drip collector (204, Figure 5 ). The drip collector (204) can be easily removed and reinserted into the front space of the main body housing (201) by holding the drip collector (204) by pulling on its tab (204A, Figure 9 ).

[0094] In this particular embodiment, the main body module (200) has four coupling blocks (218B, Figure 9 ). These blocks allow the centrifuge module (300), which also has similar coupling blocks (300A, Figure 11B ), to be placed on top of the main body module (200) and be fixed in its operating position by a smaller counterclockwise turn of the centrifuge module (300). Once the centrifuge module (300) is placed in its operating position, it cannot be removed until the operator rotates it clockwise and then pulls it up.

[0095] In this particular embodiment, the main body module (200) includes a locking mechanism that locks the centrifuge module (300) in its operating position. There are many possible embodiments for such a locking mechanism, and all of them are within the scope of this application. In this particular embodiment, such a locking mechanism consists of a flexible tag ("centrifuge locking tag", 208, Figure 9 ) located on the upper side of the top cover (218) and a small protrusion (i.e., "centrifuge locking protrusion", 300B, Figure 11B ) located at the rear bottom of the centrifuge module (300). When the centrifuge module (300) rotates counterclockwise towards its operating position, the centrifuge locking protrusion (300B) bends the centrifuge locking tag (208). Once the centrifuge module (300) reaches its operating position, the centrifuge locking protrusion (300B) releases the centrifuge locking tag (208) to straighten it, acting as a barrier for the centrifuge locking protrusion (300B). In this way, the centrifuge module (300) is locked in place until the operator manually bends the centrifuge locking tag (208) to allow the centrifuge module (300) to rotate clockwise and then pull it upwards to remove it from the main body module (200).

[0096] In this particular embodiment, the top cover (218) is a separate component attached to the main body housing (201) with screws. In other embodiments, the top cover (218) can be fixed in place by other components or can be integrated with the main body housing (201) as a single piece. The top cover (218) and the main body housing (201) can be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials.

[0097] To attach or remove the grinder module (400 or 800) from the grinding seat (210), the particular embodiment described herein for such a machine requires a locking mechanism to prevent the grinding seat (210) from rotating. Such a mechanism can be implemented in various ways. The mechanism described herein is provided as an example of one of the many possible embodiments.

[0098] An example of the centrifuge module (300) is described in Figure 2 In this particular embodiment, the toothed block (300C, Figure 11B)As a locking mechanism for the grinder base (210). When the centrifuge module (300) is turned fully clockwise, the toothed block (300C) engages with the gear (205), preventing the centrifuge module from rotating. Since the spur gear (205) is connected to the grinder base (210), the grinder base (210) cannot rotate either. This allows the operator to attach and remove the grinder module (400 or 800) from the grinder base (210). For different embodiments of the coupling mechanism between the grinder base (210) and the grinder module (400 or 800), the locking mechanism may not be required, and all variations of the locking mechanism are within the scope of this application.

[0099] The centrifuge module (300) has a cylindrical space (“grinder housing”, 300D, Figure 11A ) for accommodating the grinder module (400 or 800). The diameter of the grinder housing (300D) must be slightly larger than the outer diameter of the grinder module (400 and 800) to ensure no contact between the grinder module (400 or 800) and the grinder housing (300D). Elements in the grinder modules (400 and 800) described later in this text remove corn paste or ground product from the wall of the grinder housing (300D) and force them out of the centrifuge module (300) through the centrifuge discharge channel (300E, Figure 11A ).

[0100] Around the top edge of the grinder housing (300D) and the top edge of the centrifuge discharge channel (300E), the centrifuge module (300) has a bevel (300F, Figure 11A ) such that the centrifuge lid module (500, Figure 2 ) is flush with the top surface of the centrifuge module (300). In this particular embodiment, this feature, as described later in this text, is required for the funnel module (600, Figure 2 ) to be properly attached to the centrifuge module (300).

[0101] In this particular embodiment, there are features on the top surface of the centrifuge module (300) that allow the funnel module (600) to be attached to the centrifuge module. Many variations of this coupling mechanism can be implemented and they are all within the scope of this application. In this particular embodiment, the mechanism includes four slots (“funnel locking slots”, 300G, Figure 11A ) distributed in a circular pattern on the top surface of the centrifuge module (300) and four protrusions (“funnel locking protrusions”, 600A, Figure 13B ) extending from the bottom edge of the funnel module (600).

[0102] To assemble the funnel module (600) to the centrifuge module (300), the funnel locking protrusion (600A) must be inserted into the funnel locking slot (300G), and the funnel module (600) must be turned clockwise to lock it in place. To disassemble it, the funnel module (600) must be rotated counterclockwise and then pulled upward.

[0103] In this particular embodiment, the centrifuge module (300) includes a locking mechanism ("funnel locking mechanism") that locks the funnel module (600) in its operating position. There are many possible embodiments of such a locking mechanism and they are all within the scope of this application. In this particular embodiment, this locking mechanism consists of a flexible tab ("funnel locking tab", 301, Figure 11A ) and any one of four funnel locking protrusions (600A). When the funnel module (600) is rotated clockwise towards its operating position, one of the four funnel locking protrusions (600A) bends the funnel locking tab (301). Once the funnel module (600) reaches its operating position, the funnel locking protrusion (600A) releases the funnel locking tab (301) allowing it to straighten to act as a barrier for the funnel locking protrusion (600A). In this way, the funnel module (600) is locked in place until the operator manually bends the funnel locking tab (301) to allow the funnel module (600) to be rotated counterclockwise and then pulled upward to remove it from the centrifuge module (300).

[0104] The centrifuge module (300) can be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials.

[0105] Figure 12 A detailed example of an embodiment of the centrifuge lid module (500) is shown. In this particular embodiment, this module is constructed as a single piece and has two functions. During machine operation, this module acts as a lid for the centrifuge module (300), preventing the corn puree or ground product from splashing upward out of the centrifuge module (300). The centrifuge lid module (500) also serves as a wrench for installing and removing the grater module (400 or 800) from the grater seat (210).

[0106] The centrifuge lid module (500) has two protrusions ("wrench protrusions", 500C, Figure 12 ) protruding from two raised portions ("wrench shims", 500B, Figure 12 ). Using it as a wrench, hold the centrifuge lid module (500) with one hand by its elongated rectangular portion ("wrench handle", 500A, Figure 12 ) and insert the wrench protrusions (500C) into four circular openings ("mounting holes", 402A, Figure 16A) There are two of them, so it can be rotated clockwise to install it or counterclockwise to remove it from the grinder base (210).

[0107] When the centrifuge lid module (500) is used as a lid, the gasket (500B) prevents the operator from installing the centrifuge lid module (500) in the wrong position. The centrifuge lid module (500) must be installed with the wrench protrusion (500C) facing up. If the operator attempts to install the centrifuge lid module (500) with the wrench protrusion (500C) facing down, they may be inserted into the mounting hole (402A), but the gasket (500B) will be located on top of the grinder module (400 or 800), separating the centrifuge lid module (500) from the inclined plane (300F) of the centrifuge module (300), making it impossible to attach the funnel module (600) to the centrifuge module (300).

[0108] The centrifuge lid module (500) has a set size to longitudinally receive the central orifice of the ear of corn (centrifuge lid orifice, 500D, Figure 12 ).

[0109] The centrifuge lid module (500) can be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials.

[0110] Figure 13A and Figure 13B An example describing an embodiment of the funnel module (600) is given. In this particular embodiment, this module is attached to the top surface of the centrifuge module (300) using the funnel locking protrusion (600A) described in the previous section. The funnel module (600) has a cylindrical opening ("feed channel", 600B, Figure 13A ) through which the ear of corn (1100) is fed into the machine ( Figure 28 ). The diameter of the feed channel (600B) determines the maximum diameter of the ear of corn that the machine can handle. Once inserted into the feed channel (600B), the corn cob can be long enough to protrude from the top edge of the feed channel (600B). This is not a problem because the feed channel (600B) is long enough to keep such corn in place, so the corn cob will not fall out. Then the corn cob is further pushed into the machine using the corn relay stick module (700, Figure 2 ).

[0111] In this particular embodiment, at the bottom end of the feed channel (600B), there are two parallel rollers ("input rollers", 601) contained in a chamber (input roller housing, 600C, Figure 13B)Among them. The input roller (601) is similar to the output roller (212) described in the previous section in terms of shape, function, and material. However, the input roller (601) is larger than the output roller (212). This is because the corncobs entering the machine have a larger diameter than the naked corn cobs leaving the machine. Therefore, the two tension springs (602, Figure 13B ) used by the input roller (601) are longer than the tension spring (214) used by the output roller (212). The two axles (603, Figure 13B ) used by the input roller (601) are also longer than the axle (213) used by the output roller (212). The positioning rings (605, Figure 13B ) and spacers (604, Figure 13B ) may be the same size as the positioning ring (216) and spacer block (215) used by the output roller (212). To better understand the components that may include this module, Figure 14 a disassembled perspective view of an example of an embodiment of the funnel module (600) is provided. Since the functions of the output roller (212) and the input roller (601) are similar, Figure 14 it can also be referred to to better understand the components and features related to the output roller (212).

[0112] Two holes (600D, Figure 13A ) located on the outer body of the funnel module (600) are shown in this example. During the factory assembly of the funnel module (600) in this specific embodiment, these two holes are used to slide the axle (603) into the input roller housing (600C). Other embodiments of this module may not require these holes (600D) and those variations are within the scope of this application.

[0113] In this specific embodiment, four notches (600E, Figure 13B ) are located on the outer edge along the bottom edge of the funnel module (600). The purpose of these four notches (600E) is to facilitate access to the funnel locking tab (301), so that the operator can easily place a finger over the funnel locking tab (301) to disengage the funnel locking mechanism. These four notches (600E) are the same, and the four funnel locking protrusions (600A) located on the outer edge along the bottom edge of the funnel module (600) are also the same. This feature allows the funnel module (600) to be attached to the centrifuge module (300) in any of four possible positions.

[0114] In the specific embodiment described herein, the funnel module (600) is constructed with a conical profile in its upper part, and the inlet of the feed channel (600B) is located at the narrow end of the cone. There is a protruding edge ("funnel shelf", 600F, Figure 13A)Helps lift the funnel module (600) without the risk of slipping from the operator's hand.

[0115] The funnel module (600) can be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials.

[0116] Figure 15A and Figure 15B An example of an embodiment of the corn pusher module (700) is described in detail. In this particular embodiment, when the corn cob is initially inserted into the feed channel (600B), the corn cob may protrude from the top edge of the feed channel (600B). To effectively push the corn cob in this particular scenario and reduce the likelihood of the corn pusher module (700) slipping off the tip of the corn cob, the face of the corn pusher module (700) that pushes the corn cob ("front face", 700A, Figure 15B ) is made concave.

[0117] In this particular embodiment, the corn pusher module (700) includes a cylindrical portion ("pusher cylinder", 700B, Figure 15B ) with a diameter slightly smaller than that of the feed channel (600B), so that it can slide easily inside and outside the feed channel (600B). The length from the front face (700A) of the pusher cylinder (700B) to the pusher stopper (700C, Figure 15B ) is equal to the length of the feed channel (600B), so that when the pusher cylinder (700B) is fully inserted, the pusher cylinder (700B) can push the corn cob almost completely into the input roller (601). The pusher stopper (700C) prevents the front face (700A) of the pusher cylinder (700B) from contacting the input roller (601).

[0118] The corn pusher module (700) has a portion ("pusher handle", 700D, Figure 15A ) extending from the pusher stopper (700C). The pusher handle (700D) allows the operator to hold the corn pusher module (700) when initially pushing the corn cob into the machine.

[0119] In this particular embodiment, the pusher cylinder (700B) has a cylindrical opening ("rod channel", 700E, Figure 15B ) extending from the front face (700A) to the plane of the pusher handle (700D). A rod ("pusher rod", 701, Figure 15B)Passes through the rod channel (700E), extends from the front end face (700A) of the baton cylinder (700B) and protrudes from the baton handle (700D). The baton cylinder (700B) also serves as a guide for the baton rod (701) when inserted into the machine. The baton rod (701) has a wider diameter portion (“rod stopper”, 701A, Figure 15B ) on one side flush with the front end face (700A), and has a wide disk (“rod pusher”, 701B, Figure 15B ) at its other end. The rod stopper (701A) prevents the baton rod (701) from further sliding into the interior of the baton cylinder (700B). The rod pusher (701B) allows the operator to comfortably push the baton rod (701) through the rod channel (700E) and out from the front end face (700A) to further push the corncob into the interior of the machine. The front end face (700A) end of the rod channel (700E) has a wider diameter portion that allows the rod stopper (701A) to be inserted into the rod channel (700E) and be flush with the front end face (700A). The length of the baton rod (701) is long enough to fully push the corncob through the conical grinder module (400) and the output roller (212) until the naked corncob comes out of the machine. The diameter of the rod stopper (701A) is small enough to pass through the center of the conical grinder module (400) and not touch the conical grinder blades (404, Figure 16A ) even when the conical grinder blades are fully closed. Similarly, the rod stopper (701A) can pass through the center of the output roller (212) without touching them.

[0120] In this particular embodiment, the corn baton module (700) has a compression spring (702, Figure 15B ) between the baton handle (700D) and the rod pusher (701B) along the length of the baton rod (701). The compression spring (702) has an inner diameter slightly larger than that of the baton rod (701), so the baton rod (701) can freely slide within the coils of the compression spring (702) when pushed by the operator. When the operator is not pushing, the compression spring (702) keeps the rod pusher (701B) separated from the baton handle (700D). This feature is not necessary for the operation of the machine, but facilitates its operation. On the planar side of the baton handle (700D), the rod channel (700E) has a diameter portion slightly larger than the outer diameter of the compression spring (702). This portion runs deep enough to allow the compression spring (702) to be fully accommodated within the baton handle (700D) when the operator pushes the baton rod (701) fully into the machine.

[0121] Other embodiments of the module may perform the same function. One possible embodiment may integrate the baton cylinder (700B) and the baton rod (701) into a single piece, where the baton rod (701) pushes the corn cob and the baton cylinder (700B) serves as a guide for centering the baton rod (701) when it is inserted into the machine.

[0122] The corn baton module (700) may be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials. The compression spring (702) may be made of stainless steel, hard plastic, or other suitable food-grade materials.

[0123] Figure 16A and Figure 16B An example of an embodiment of the conical grater module (400) (also referred to as the "grater") is described. In this particular embodiment, the grater includes two discs with various components between them. Each disc has a circular opening through which the corn cob passes at the center. The conical grater module (400) is connected to the grating seat (210) placed within the grater housing (300D) as described in the previous paragraph. The chassis ("chassis", 401, Figure 16B ) has a number of grooves ("grater grooves", 401C, Figure 16B ) on its outer surface, and these grooves are inclined with respect to the circumferential radius of the disc. When the conical grater module (400) rotates at high speed, the grater grooves (401C) help to push any contents (corn paste or others) that may attempt to escape through its circular bottom opening rather than through the discharge channel (300E) into the grater housing (300D). To maximize this effect, the conical grater module (400) rotates at a distance close to the inner bottom surface of the grater housing (300D).

[0124] The diameter of the circular opening at the center of the chassis (401) of the conical grater module (400) is large enough to allow a bare corn cob to pass through it. Similarly, the diameter of the circular opening (grater orifice, 402B, Figure 16A ) at the center of the top disc (402, Figure 16A ) is large enough to allow an unground corn cob to pass through it.

[0125] In this particular embodiment, the chassis (401) has four circular openings ("chassis pin holes", 401D, Figure 16C ) through which the conical grater pins (403, Figure 16B ) are inserted. The top disc (402) has similar circular openings for the same purpose. Around the four chassis pin holes (401D), there are four wide rings ("blade seats", 401E, Figure 16C)Protrudes from the top surface of the chassis (401) to provide support for the conical grinder blades (404). When the four conical grinder blades (404) move during operation as described later in this text, the blade seat (401E) keeps the conical grinder blades (404) away from the chassis (401).

[0126] Four blocks (“blade stoppers”, 401F, Figure 16C ) also protrude from the top surface of the chassis (401). The blade stoppers (401F) prevent the conical grinder blades (404) from rotating too far inward, and their position and geometry determine the minimum passage size left at the center of the conical grinder module (400) during machine operation.

[0127] In this particular embodiment, the chassis (401) and the top plate (402) are interconnected by four vertical members (“sweeper blades”, 405, Figure 16A ) and four conical grinder pins (403). The sweeper blades (405) are inserted into four rectangular slots (sweeping slots, 401G, Figure 16C ) located on the chassis (401) and the top plate (402). The sweeper blades (405) remove the corn paste on the wall of the grinder housing (300D), pushing it out of the centrifuge module (300) through the centrifuge discharge channel (300E). The sweeper blades (405) are inclined with respect to the circumferential radius of the chassis (401) and the top plate (402), so when the conical grinder module (400) rotates at high speed, the air flow generated by the sweeper blades (405) helps prevent any contents (corn paste or others) from escaping from the centrifuge module (300) through its circular bottom opening. This air flow also helps move the corn paste or other grinding materials inside the centrifuge module (300) towards the centrifuge discharge channel (300E).

[0128] The chassis (401), the top plate (402), and the sweeper blades (405) can be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials.

[0129] The conical grinder pins (403) provide a firm connection between the chassis (401) and the top plate (402), and at the same time provide support and a rotation point for the conical grinder blades (404). The geometry of the conical grinder pins (403) is shaped in parts of different diameters according to their various functions. In this particular embodiment, the top plate bracket part (403A, Figure 17 )(shown riveted) is riveted during the factory assembly of the conical grinder module (400) to keep the top plate (402) in place. The top plate neck part (403B, Figure 17 ) provides a guide for the top plate (402) to slide into position. The blade top guide part (403C, Figure 17)As a rotating shaft for the top pin holes (404C, Figure 18 ) of the conical grater blade (404). The blade bottom guide part (403D, Figure 17 ) serves as a rotating shaft for the bottom pin holes (404D, Figure 18 ) of the conical grater blade (404). The chassis neck part (403E, Figure 17 ) provides guidance for the chassis (401) to slide into position. The chassis bracket part (403F, Figure 17 )(shown riveted) is riveted during the factory assembly of the conical grater module (400) to keep the top plate (402) in place.

[0130] The conical grater pin (403) can be made of aluminum, metal alloy, or other suitable food-grade materials. For this particular embodiment, stainless steel is recommended.

[0131] The conical grater blade (404) grinds the kernels of a corncob to produce corn puree. In this particular embodiment, each of the four conical grater blades (404) has two circular openings ("top pin holes", 404C and "bottom pin holes", 404D) through which the conical grater pins (403) are inserted. The conical grater blades (404) pivot around the conical grater pins (403), and by doing so, the conical grater blade teeth (404A, Figure 18 ) located on the face of the conical grater blade (404) ("grinding surface", 404B, Figure 18 ) move closer to or farther from the center of the circular opening of the conical grater module (400), reducing or increasing the size of the passage through which the corncob is ground by the four conical grater blades (404). Figure 26A A top view showing the four conical grater blades (404) in the fully open position and Figure 26B A top view showing the four conical grater blades (404) in the fully closed position. For optimal grinding results, this movement allows the conical grater blades (404) to mimic the shape of the corncob. To allow the corncob to push the conical grater blades (404) away from the central opening as it passes through the conical grater module (400), the grinding surface (404B) is inclined with respect to the line of movement of the corncob. This feature also allows the kernels to be ground gradually as the corncob is inserted into the conical grater module (400), resulting in a smoother grinding process. Figure 27 A cross-sectional view showing the conical grater module (400) with a corncob (1100, Figure 27 ) being ground. The part of the corncob above the conical grater module (400) shows all intact kernels (1100A, Figure 27)。When they contact the conical grinder blade (404), the corn kernels (1100A) are gradually ground, producing a conical profile ("grinding profile", 1100B, Figure 27 )。After leaving the conical grinder module (400), all the remaining corn cobs are bare corn cobs (1100C, Figure 27 )。

[0132] In the specific embodiment described herein, the conical grinder blade teeth (404A) are vertically aligned with column - to - column cancellation, so that when the grinding surface (404B) is viewed from the side, there are no toothless spaces from top to bottom. In this specific embodiment, the conical grinder blade teeth (404A) are in the shape of round holes with four triangular spikes protruding from the edge of each hole. Other embodiments of the present application may use different distributions and shapes of teeth to achieve different corn puree textures, all of which are within the scope of the present application.

[0133] The conical grinder blade (404) can be made of a metal alloy sheet or other suitable food - grade material. For this specific embodiment, a stainless - steel sheet is recommended.

[0134] In this specific embodiment, each conical grinder blade (404) has a small piece ("counterweight", 406, Figure 16A ) attached to the grinding surface (404B). The counterweight (406) is located near the pin holes (404C and 404D). In the specific embodiment represented herein, the counterweight (406) is attached to the grinding surface (404B) using two rivets (407, Figure 18 ) passing through the rivet holes (404E, Figure 19 ) located on the grinding surface (404B). In other embodiments, different attachment members may also be used, or the counterweight (406) can be constructed as a single piece with the conical grinder blade (404).

[0135] The counterweight (406) is attached to the conical grinder blade (404) at a position relative to the conical grinder pin (403) such that, relative to the position of the conical grinder pin (403), the centroid of the counterweight (406) is on the opposite side of the centroid of the conical grinder blade (404). When the conical grinder module (400) starts to rotate at high speed, the weight of the counterweight (406) is large enough so that the centrifugal force generated by the counterweight (406) exceeds the centrifugal force generated by the conical grinder blade (404), forcing the conical grinder blade (404) to pivot around the conical grinder pin (403), moving the part where the conical grinder blade teeth (404A) are located to the central circular opening of the conical grinder module (400), allowing the corn cob to be ground when passing through the passage formed by the four conical grinder blades (404) at the center of the conical grinder module (400).

[0136] The counterweight (406) can be made of a metal alloy or other suitable food-grade material. For this particular embodiment, stainless steel is recommended.

[0137] Alternative embodiments of the present application may use different means to push the conical grater blade (404) towards the central circular opening of the conical grater module (400), all of which are within the scope of the present application. In these alternative embodiments, the counterweight (406) may not be required. One possible option may include the use of a spring (408, Figure 32 ).

[0138] For increased clarity, Figure 19 an exploded perspective view of an example of a conical grater module (400) showing all of its components according to this particular embodiment is provided.

[0139] Figure 20A An example of a flat grater module is described, also known as a grater (800, Figure 2 ). The flat grater module (800) is used for grating vegetables or other suitable products. In this particular embodiment, the module is interchangeable with the conical grater module (400), so the two modules have many similarities but also some differences.

[0140] Except for not having a central circular opening on the chassis (801) of the flat grater module (800), the bottom surface of the chassis (801, Figure 20A ) of the flat grater module has the same features and functions as those described in the previous section for the conical grater module (400). The two modules also share four similar sweeper blades (804, Figure 20A ) and four pins ("flat grater pins", 803, Figure 20A ), but in the case of the flat grater module (800), the only function of the flat grater pins (803) is to provide a secure connection between the chassis (801) and the top plate (802, Figure 20A ). Therefore, the geometry of the flat grater pins (803) is different from that of the conical grater pins (403).

[0141] Figure 21 An example of an embodiment of the flat grater pin (803) is shown in detail. In this particular embodiment, the top plate bracket portion (803A, Figure 21 )(shown riveted) is riveted during the factory assembly of the flat grater module (800) to keep the top plate (802) in place. The top plate neck portion (803B, Figure 21 ) provides a guide for the top plate (802) to slide into position. The disc spacer portion (803C, Figure 21)Establish the required distance between the chassis (801) and the top plate (802). The chassis neck portion (803D, Figure 21 ) provides a guide for the sliding-in position of the chassis (801). The chassis support portion (803E, Figure 21 )(shown riveted) is riveted during the factory assembly of the flat grinder module (800) to keep the chassis (801) in place.

[0142] In this particular embodiment, the top surface of the chassis (801) has four radially protruding segments ("blade seats", 801A, Figure 20B ) that are spaced 90 degrees apart from each other. The blade seats (801A) do not reach the center or the outer edge of the disc. Their function is to provide support for the flat grinder blades (805, Figure 20A ) such that they are separated from the chassis (801) with sufficient clearance for the ground product to fall loose. In the particular embodiment described herein, the flat grinder blades (805) are fixed to the blade seats (801A) by screws (screws, 806, Figure 22 ) passing through four through mounting holes (805B, Figure 20A ). Other embodiments of the module may fix the flat grinder blades (805) in place by other means, and all of these are within the scope of this application.

[0143] In the particular embodiment described herein and Figure 22 shown in detail therein, the flat grinder blades (805) are circular, and the flat grinder teeth (805A, Figure 22 ) are distributed along several radial lines. The distance from the center of the flat grinder blade (805) to the teeth is different from line to line, so that when the flat grinder blade (805) rotates, there is no toothless space along the radius of the flat grinder blade (805). In the particular embodiment described herein, the flat grinder teeth (805A) are in the shape of a semi-circular hole resulting from the absence of half of the circle, and the other half bends upward from the surface of the flat grinder blade (805) to produce a semi-circular cutting edge. Different distributions, shapes, and sizes of teeth are suitable for different grinding requirements and all of these are within the scope of this application.

[0144] In this particular embodiment, the top plate (802) of the flat grinder module (800) has the same features and functions as the top plate (402) of the conical grinder module (400), except that on the flat grinder module (800), the central circular opening of the top plate (802) has a larger diameter, sufficient to allow the funnel sleeve module (900, Figure 2 ) to pass through the circular opening without contacting its edge.

[0145] The flat grater blade (805) can be made of a metal alloy sheet or other suitable food-grade material. In this particular embodiment, a stainless steel sheet is recommended. The flat grater pin (803) can be made of aluminum, a metal alloy, or other suitable food-grade material. In this particular embodiment, stainless steel is recommended. The flat grater chassis (801), top plate (802), and sweeper blade (804) can be made of aluminum, a metal alloy, a hard plastic, or other suitable food-grade material.

[0146] The feed channel (600B), socket (218C), grater orifice (402B), and centrifuge lid orifice (500D) are all coaxially centered about the central axis (2000A, Figure 31 ).

[0147] Figure 23A and Figure 23B An example describing an embodiment of the funnel sleeve module (900) is provided. The funnel sleeve module (900) is only intended to be used in conjunction with the flat grater module (800). It cannot be used in conjunction with the conical grater module (400). When the operator fully inserts the funnel sleeve module (900) into the feed channel (600B), it protrudes from the bottom of the funnel module (600). To install the funnel sleeve module (900), the input rollers (601) must be pushed apart from each other to allow the funnel sleeve module (900) to pass between them. When the machine is fully assembled and the funnel sleeve module (900) is fully inserted, the bottom of the funnel sleeve module (900) passes through the centrifuge lid orifice (500D) and through the circular central opening of the top plate (802) of the flat grater module (800), reaching very close to the flat grater teeth (805A).

[0148] In this particular embodiment, the funnel sleeve module (900) is provided with a groove ("sleeve groove", 900A, Figure 23A ) around its outer periphery and at a certain distance from the bottom edge so that when the funnel sleeve module (900) is fully inserted into the feed channel (600B), the input rollers (601) firmly hold the funnel sleeve module (900) through the sleeve groove (900A), preventing the funnel sleeve module (900) from rotating during operation. The top of the funnel sleeve module (900) has a wider flat portion ("neckline", 900B, Figure 23A ) that prevents the funnel sleeve module (900) from being further inserted into the feed channel (600B). During disassembly, the operator also uses the neckline (900B) to grasp the funnel sleeve module (900) and pull the funnel sleeve module (900) out of the feed channel (600B). Additionally, the funnel sleeve module (900) has a square-profile post ("sleeve key", 900C, Figure 23B ) on its inner surface from top to bottom. The use of the sleeve key (900C) will be described later in this document.

[0149] In a preferred embodiment of the present application, the use of the flat grinder module (800) requires the use of a flat grinder relay stick module (1000, Figure 2 ) to push any suitable product towards the flat grinder blade (805). Note that corn cobs cannot be ground using the flat grinder module (800). An example of an embodiment of the flat grinder relay stick module (1000) is shown in Figure 24 shown in more detail.

[0150] In this particular embodiment, the flat grinder relay stick module (1000) has a cylindrical portion ("relay stick cylinder", 1000A, Figure 24 ) with a diameter slightly smaller than the inner diameter of the funnel sleeve module (900), so that the flat grinder relay stick module (1000) can slide easily inside and outside the funnel sleeve module (900). The length of the relay stick cylinder portion (1000A) is equal to the length of the funnel sleeve module (900), and the relay stick stopper (1000B, Figure 24 ) prevents the flat grinder relay stick module (1000) from being inserted further into the funnel sleeve module (900). Thus, when fully inserted, the flat grinder relay stick module (1000) does not contact the flat grinder teeth (805A).

[0151] In this particular embodiment, the flat grinder relay stick module (1000) has a portion ("relay stick handle", 1000C, Figure 24 ) extending from the relay stick stopper (1000B), which the operator uses to hold the flat grinder relay stick module (1000) during operation. The surface of the flat grinder relay stick module (1000) that contacts the product to be ground ("textured surface", 1000E, Figure 24 ) has a rough texture to minimize the rotational movement of the product during the grinding operation, thereby improving the effectiveness of processing in this way. In this particular embodiment, the texture consists of a grid of small square-based pyramids, but many different geometries can be used in other embodiments, all of which are within the scope of the present application.

[0152] Another feature of the flat grinder relay stick module (1000) described herein that appears in a particular embodiment is a square-profile groove ("relay stick groove", 1000D, Figure 24)。The profile of the relay rod groove (1000D) is slightly larger than the profile of the sleeve key (900C). This feature allows the relay rod groove (1000D) to easily slide over the sleeve key (900C) when the flat grinder relay rod module (1000) is inserted into and removed from the funnel sleeve module (900), preventing the flat grinder relay rod module (1000) from rotating in this way within the funnel sleeve module (900) if any rotational force is transmitted from the product being ground to the textured surface (1000E) of the flat grinder relay rod module (1000) during the grinding operation.

[0153] The funnel sleeve module (900) and the flat grinder relay rod module (1000) can be made of aluminum, metal alloy, hard plastic, or other suitable food-grade materials.

[0154] In this particular embodiment, as Figure 1 shown, the machine is intended to be operated with a power switch (108) facing the operator. This causes the feed channel (600B) to point in the upper right side direction and the bare corn cobs to exit from the lower left side of the machine. When using his or her right hand to push the corn ear with the corn relay rod module (700) or to push vegetables or other suitable products with the flat grinder relay rod module (1000), the operator is encouraged to place his or her left hand on the funnel module (600). During its use, this operating mode provides additional stability to the machine.

[0155] All machine surfaces that may come into contact with the processed food must be made of food-grade materials. As a result of machine operation or cleaning after each use, all metal parts that will come into contact with food or water must be made of rust-proof food-grade metal. Stainless steel is preferred for most metal parts.

[0156] Although the preferred materials for each element have been described, the device is not limited to these materials. In various embodiments of the present application, plastics, rubbers, metal alloys, aluminum, and other materials may include some or all of the elements of the electric corn separator and the food grinder.

[0157] An important version of the present application can be fairly described as a corn separation device, including a motor base 100, a main body 200, a centrifuge 300, a grinder 400, and a funnel 600. Generally, a motor 103 is disposed within the motor base 100. In some versions of the present application, the motor 103 can be replaced by a hand crank or power output on other motor devices. The funnel 600 includes a feed channel 600B having a plurality of corn contact points 601. The corn contact points can be described in the above forms and can include, for example, rollers, points, guides, or other features that tend to center the corn ear within the feed channel 600B and restrict the axial rotation of the corn ear within the feed channel 600B. Each corn contact point 601 is symmetrically oriented about a central axis 2000A to keep the corn ear centered. The corn contact points 601 are biased together and spaced apart to contact the corn ear when the corn ear passes through the corn contact points 601 at the center of the feed channel 600B. The corn contact points 601 are biased together to allow corn ears of different diameters to pass through the feed channel 600B and remain in contact with the corn contact points 601. The grinder 400 is sized to longitudinally receive a grinder orifice 402B of a corn cob 1100. The grinder 400 is disposed within the centrifuge 300 and is operably coupled to the motor 103 so that the grinder 400 rotates within the centrifuge 300. A plurality of grinder blades 404 surround the grinder orifice 402B and are fixed to the grinder 400. Each of the plurality of grinder blades 404 is attached to a grinder pin 403, and each grinder blade 404 pivots about the grinder pin 403. Each grinder blade 404 has a grinding surface 404B facing the grinder orifice 402B. The grinder blades 404 are each biased toward the center of rotation of the grinder orifice 402B such that each grinding surface 404B contacts the corn ear 1100 simultaneously. The centrifuge 300 is covered by a centrifuge lid 500 having an orifice 500D sized to longitudinally receive the corn ear 1100. The centrifuge 300 has a discharge channel 300E through which portions of the corn kernels cut off by any of the grinder blades 404 are discharged. The main body 200 includes a socket 218C and a plurality of corn cob contact points 212. The socket 218C is sized to longitudinally receive a naked corn cob 1100C. Each corn cob contact point 212 is biased together and spaced apart to contact the naked corn cob 1100C in a manner similar to the above-described corn contact points 601. The naked corn cob 1100C passes between the corn cob contact points 212 at the center of the socket 218C, thereby preventing the corn ear 1100 from rotating axially. The feed channel 600B, the socket 218C, the grinder orifice 402B, and the centrifuge lid orifice 500D are all centered coaxially about the central axis 2000A. Optionally, when the motor 103 rotates the grinder 400, the grinder blades 404 are biased toward the center of the grinder 400 due to the centrifugal force of a counterweight 406 affecting each grinder blade 404.Optionally, the shredder blade 404 is biased towards the center of the shredder 400 by a spring 408. Optionally, a plurality of sweeper blades 405 are radially fixed to the shredder 400 and rotate with the shredder 400 to push portions of the corn kernels towards the discharge channel 300E. Optionally, a blade stopper 401F is provided for each shredder blade 404 and is fixed to the shredder 400 to limit the maximum inward bias of the respective shredder blade 404. Optionally, any corn contact point 601 and cob contact point 212 can be selected from any single type or combination of the following: rolling blade, rolling gear, rolling rack, or sliding blade. Another important version of the present application can be fairly described as a method of separating corn using any variant of the device described herein, by longitudinally inserting the first end of the ear of corn into the feed channel 600B, then pushing the second end of the ear of corn to force the entire ear of corn through the shredder 400, then collecting portions of the corn kernels in the discharge channel 300E, and then removing the bare cob through the socket 218C.

[0158] Although the present application has been illustrated and described with reference to the preferred embodiments and specific examples herein, other embodiments and examples that perform similar functions and / or achieve similar results will be apparent to those of ordinary skill in the art. All such equivalent embodiments and examples are within the spirit and scope of the present application and are thus contemplated and intended to be covered by this specification.

[0159] Industrial Applicability

[0160] Obviously, inventions such as electric corn separators and food grinders are highly desirable in any iteration in which they are included, as they enable the quick and precise removal of corn kernels from the cob with minimal waste and effort and maximum efficiency and safety. The device is also adapted to grind foods other than separating corn. The device is inexpensive to manufacture and maintain and is economical to operate.
