[0004] US Patent No. 4,479,614 refers to a meat grinder that includes a pump that feeds meat particles into a mixing chamber at a constant flow rate. The meat exits through a frusto-conical collection chamber for passage to a grinder plate. A rotating knife with radially extending blades is rotated by a hydraulic motor at a variable rate. The variable flow rate of the particles into the chamber and the variable speed of the knife result in a variable particle size output through the grinder plate.

[0005] US Patent No. 3,986,227 refers to a printing system for copier paper with toner that is fused by a pressure nip formed by a thermal roller and a backup roller. A scraping blade engages the destructible surface of the backup roller at a critical angle that is selected by the coefficients of friction of the backup roller surface and the toner debris contamination collected on the backup roller surface. As a result, the blade slides freely over the roller surface but does not slide over the surface of the contaminant film. This film forms a locking angle with the blade, placing the blade under tension and developing an action that resembles a chisel removing film.

[0006] US Patent No. 4,184,429 relates to a doctor blade scraping blade for cleaning excess ink from a printing surface of a printing form together with a method for making a doctor blade scraping blade and printing equipment. The scraping blade comprises a body with a constant blade thickness between parallel blade surfaces and a pointed portion of Petition 870220092174, dated 07 / 10 / 2022, page 13 / 41 3 / 28 marginal blade adjacent to the body of the scraping blade with a shaped blade bevel essentially identical to the run-in blade bevel of a wedge-shaped blade. Throughout the blade tip portion, the scraping blade has a blade tip thickness of contact equal to the height of the shaped blade bevel. As a consequence, the effective area of ​​the shaped blade bevel remains consistently at the ideal size, despite the progressive wear of the marginal blade tip portion in the direction of and throughout the useful depth during the overpaint cleaning operation.

[0007] US Patent No. 4,257,343 refers to a coating of a strip of material that is passed over a support member forming one of the bounding surfaces of a closed chamber. The closed chamber operates under vacuum conditions. Excess coating liquid is supplied to the closed chamber to form a layer on the surface of the strip. At the end of the coating action, as the strip leaves the closed chamber, it is contacted by a movable, positionable blade that provides a cleaning action on the strip to remove excess coating liquid. The vacuum inside the closed chamber presses the blade against the strip. Therefore, by varying the vacuum, the amount of liquid coating adhering to the strip leaving the closed chamber is varied.

[0008] US Patent No. 4,782,756 refers to a printing roller ink coating remover having a solid ink transfer roller. The invention includes a plurality of side-by-side scraping blades that selectively engage the roller to remove transferred ink.

The blade is configured for controlled deflection about the main frame when vertical forces in excess of a predetermined force are met, to prevent damage to the surface or object. The retention portion and the treatment portion are arranged in mutual angular spatial relation for ease of use of the tool. The support tool provides support to the object during treatment. Petition 870220092174, dated 07 / 10 / 2022, page 15 / 41 5 / 28

[00012] US Patent No. 8,086,133 refers to a cleaning station for removing particulate material from a moving screen in an electrographic copier / printer that includes a screen cleaning device with a support shoe assembly. The screen cleaner has two cleaning blades, including one or more blades, each with a differentiation that distinguishes one cleaning blade from the other when the blades are locked into the cleaning reservoir by springs.

[00013] U.S. Patent No. 8,401,446 relates to a printing method and apparatus including a loading device positioned adjacent to a photoreceptor that places a latent image charge onto the photoreceptor. An auxiliary transfer blade is adjacent to the photoreceptor that presses the media sheet against the photoreceptor to cause the marking material to be transferred to the media sheet. The apparatus also includes a controller that is operatively connected to the auxiliary transfer blade. The controller causes the auxiliary transfer blade to apply more pressure to the front and back portions of the media sheet relative to the middle portion of the media sheet.

[00014] In the prior art, conventional meat grinders used a screw-type conveyor to advance meat particles through a chamber to force them through a grinder plate disposed at the end of the chamber. The grinder plate typically has a plurality of holes arranged throughout it for reducing the size of the meat particles. Grinding is usually started with pieces of meat the size of baseballs which are then reduced to a desired size, which may lead to several stages of grinding.

[00015] Screw-type meat grinders require a defined clearance between the screw conveyor and the sides of the chamber through which the Petition 870220092174, dated 07 / 10 / 2022, p. 16 / 41 6 / 28 of the meat is passed through. This clearance allows the screw conveyor to clean the walls as it rotates. However, this clearance allows the meat to flow back around the screw conveyor under high-pressure conditions, thereby reducing the maximum amount of pressure that can be applied to the meat particles on the grinder plate. This pressure limit defines the maximum flow rate of meat that can be passed through a grinder plate. In addition, cartilage or bone chips that may be present in the meat can clog the grinder plate and further inhibit grinding.

[00016] In grinding meat to a desired particle size in a large-scale production environment, it was necessary to change the grinder plates at various stages of the operation. Since it is very difficult to go from a large particle size to a very small particle size, a number of stages is necessary. When the meat is removed from the grinder plate, it assumes a very sticky texture, since the meat and fat fibers tend to adhere together along the longitudinal direction. Therefore, the grinding operation requires an additional step to reduce the length of this material. All these operations must be repeated for each grinding stage.

[00017] The meat industry has attempted to control fiber length during production through multiple designs. The best previous method is an industrial grinder, dependent on operator control, a batch system that reduces production.

[00018] Meat grinders do not cut fiber to specified lengths. Meat grinders perform meat extrusion using hydraulic pressure, forcing the product through holes; the internal grinder blades are sweepers that clean holes of material that may bind them. This extrusion process does not control fiber length, subjects the product to very high pressure, and fails to achieve the desired product quality. In the state of the art, even if the Petition 870220092174, dated 07 / 10 / 2022, page 17 / 41 7 / 28 internal grinder blades can be run at a speed designed to cut the fiber to the desired length; however, at this stage of production, it is not possible to stretch the meat and align the fibers.

[00019] Current forming technology relies on high pressure, speed, and complicated material flow paths that produce a product lacking in quality. High pressure works the meat cells; the higher the pressure, the more massage, tightening, and turbulence of the meat cells occur. High speed combined with a complicated flow path increases pressure and turbulence and works the meat product, releasing and mixing myosin / actin from the cells, causing the muscle fibers to bind and contract (protein binding). Contraction occurs during the application of high temperature, such as during cooking. The action of the meat fiber is to contract in length; this contraction combined with protein binding not only shortens the muscle fiber, which, if uncontrolled, causes strange cooking shapes, but also a texture that resembles rubber with a strong bite.

[00020] In muscle, actin is the main component of thin filaments, which together with the motor protein myosin (which forms thick filaments), are arranged in actomyosin myofibrils. These fibrils comprise the mechanism of muscle contraction. Using ATP hydrolysis for energy, myosin heads go through a cycle during which they attach to thin filaments, exerting tension, and then, depending on the load, deliver a burst of energy that causes the thin filaments to slide along them, shortening the muscle.

[00021] Muscle fibril structure is measured from micrometers to several millimeters in length. These fibril structures are grouped together to form muscles. Myofibril proteins are the largest group and probably more is known about these proteins than any other. In muscle cells, actin is the platform upon which myosin proteins generate force to support muscle contraction. Myosin Petition 870220092174, dated 07 / 10 / 2022, page 18 / 41 8 / 28 is the main protein that is extracted from muscle cells by mechanical means.

[00022] An important purpose of rolling and massaging is to solubilize and extract myofibril proteins to produce a protein exudate on the surface of the meat fiber. The exudate binds the formed pieces together after heating. Binding strength also increases with increasing massaging or mixing time. This is due to the increased formation of exudate on the meat surface. Crude myosin extrudate is increased with increasing mixing time.

[00023] Milling / cutting utilizes the concept of breaking the cell to release the protein. This mechanical cutting or shearing occurs in the hole of the filling / shear plate. This process extracts actin and myosin from muscle cells.

[00024] When mixing, it uses friction and kinetic energy to release protein exudate. The shape and spacing of the filling holes can cause dead spots and turbulence in the meat flow. This change of direction is a form of mixing and massaging. This is another process that extracts actin and myosin from muscle cells.

[00025] When massaging, it uses friction, kinetic energy, and pressure to increase protein exudate. This action occurs wherever meat comes into contact with processing equipment and is moved or has a change of direction through pressure. This is also a procedure that involves extracting actin and myosin from muscle cells.

[00026] Ground meat mixtures are composed of whole muscle meat, meat trimmings, or LFTB (lean finely textured beef) or a combination thereof.

[00027] A grinder / mixer combines the product to grind either a coarse or fine grind, creating a finished product. This creates a homogeneous mixture that is formed into noodles. Petition 870220092174, dated 07 / 10 / 2022, page 19 / 41 9 / 28

[00028] With frozen foods, a food processor can be used that first crushes the frozen food into flakes, which is then ground in a grinder / mixer / blender. SUMMARY OF THE INVENTION

[00029] The present invention relates to machined holes in the grinder plate that create the orientation of the meat fiber and elongation of the product fibers. It is an object of the present invention that the fibers, while aligned and stretched, pass through the holes at such a high speed that the fibers are cut to the desired length. It is an object of the present invention to install a series of independently controlled speed blades on the outside of the grinder plate.

[00030] It is an object of the present invention to use machined holes that control the fiber orientation. It is an object of the present invention to have the grinder extrude the product, accelerate the product through the holes, resulting in fiber alignment and stretching, while simultaneously allowing the outer blades to have the opportunity to shear the fibers to any desired length. Having the fibers in the aligned, stretched state at the exit of the holes is the only point at which to shear them. It is an object of the present invention to have an independent series of blades that can be controlled by speed, allowing control of the fiber length.

[00031] The present invention relates to an independent knife assembly, with variable speed control, for shearing cut fibers affected by the holes.

[00032] It is an object of the present invention to provide an external knife assembly for a grinder.

[00033] It is an object of the present invention to provide an external knife assembly for stuffing machines, or any other meat extrusion machine or device. Petition 870220092174, dated 07 / 10 / 2022, page 20 / 41 10 / 28

[00034] It is an object of the present invention to provide independent speed control of the external knife assembly. It is an object of the present invention that the device is driven by a hydraulic, electrical, pneumatic or any other power transfer system.

[00035] It is an object of the present invention that the rotating drum of the knives has a method driven by gears, belt, chain, or any other method to transfer energy to the rotating drum of the knives. It is an object of the present invention that the device to be attached through a segment, sliding joint with retaining pin, fixing collar, as shown in the figures, an interrupted segment, flange with bolts, a U-shaped sliding socket with protrusions or locking bolts.

[00036] It is an object of the present invention that the external knife used is a standard off-the-shelf configuration. It is an object of the present invention that the external knife is redesigned as required for different applications. It is an object of the present invention that the external knife is a knife insert. It is an object of the present invention that the external knife has a thickness equal to or less than the diameter of the holes. This will prevent the external knife from causing windowing of the hole until it is completely closed, thus blocking the flow and pulsation of the meat.

[00037] During the start and stop of the meat flow, the cylinder needs to be cleaned before the venturi action takes effect. It is an object of the present invention that the spherical portion of the orifice be shorter in length than the cylinder portion or outlet of the holes.

[00038] It has been shown that there is a relationship between the ratio of the length of the spherical portion to the length of the cylindrical portion. The venturi effect, when subjected to start-stop or pulsed flow action, performs better with a long spherical portion and a short cylinder by ratio. Petition 870220092174, dated 07 / 10 / 2022, p. 21 / 41 11 / 28

[00039] It is an object of the present invention that the drum device has a scraper assembly. The scraper assembly prevents the meat from falling like a clothes dryer, moving the meat out of the way so that there is less contact time with the drum. It directs the meat in a controlled manner and acts as a safety device in case the device is not installed correctly.

[00040] It is an object of the present invention that the knife ring unit part uses three square notches with three raised tabs.

[00041] The present invention comprises an apparatus for grinding meat. The meat grinder includes a pump for pumping meat particles in a continuous stream under high pressure. This meat is pumped to the inlet port of a collection chamber which has a frustoconical shape with the outlet port of larger diameter. A grinder plate is disposed at the outlet port of the collection chamber with a plurality of holes arranged therein to reduce the diameter of the meat particle size as the meat is pressed through it. An external knife is disposed adjacent to the grinder plate to reduce the length of the suspended particle outlet from the grinder plate. A variable motor is attached to the external knife to move the external knife perpendicular to the surfaces of the grinder plate. The variable motor has a variable speed, such that the length of the suspended particle outlet from the grinder plate is varied depending on the specific application.

[00042] In accordance with another embodiment of the present invention, the variable motor is a hydraulic motor with an external pump to provide hydraulic pressure to it. This hydraulic motor has a continuously variable speed to rotate the external knife at a variable rotational speed. By varying the rotational speed of the external knife, the length of the particle size pressed through the Petition 870220092174, dated 07 / 10 / 2022, page 22 / 41 The 12 / 28 plate grinder can be set to a desired particle size.

[00043] In one embodiment, the grinder, by means of its auger, conveys meat through the grinder plate. The external knife cuts the meat again. The blade's rotation speed affects the fiber length. The speed is adjustable by means of a speed control device connected to the motor. The motor drives the external knife through a unit that is mechanically connected from the input shaft to the knife connector (hub) of the external unit. The contact of the external knife to the grinder plate is adjusted by the tension ring assembly with pressure on the external knife.

[00044] It is an object of the present invention to provide fiber guidance technology to reduce the release and mixing of myosin with actin. It is an object of the present invention that the fiber guidance technology controls the orientation of the fiber. It is an object of the present invention that the fiber guidance technology provides less myosin activity, resulting in better bite / binding and control over the final shape of the food.

[00045] The present invention relates to an apparatus and method for accelerating a food product in order to cause the product to be stretched, aligning the fibers of the product. It is an object of the present invention that a hole or orifice changes the size from a larger diameter to a smaller diameter with vertical or concave sides. It is an object of the present invention that the sides have a sharp edge. The principle has design similarities to a venturi. It is referred to as a nozzle, venturi, orifice, or a flow restriction that results in the acceleration of the product with a corresponding pressure drop across the orifice.

[00046] By reducing the diameter of a tube through which a substance passes, the speed is increased. This is the principle of Petition 870220092174, dated 07 / 10 / 2022, p. 23 / 41 13 / 28 Conservation of mass. When speed increases, the pressure of the material is reduced. This is the principle of conservation of energy.

[00047] For each liquid, there is a ratio between the cross-sectional area (C) and the cross-sectional area (c) through which the velocity can only be increased by reducing the temperature or increasing the pressure. Although ground meat is not a homogeneous liquid, the same concepts still apply. It is impossible to achieve a venturi effect unless there is a transition between the orifices and the small orifice has a finite length. There is a length ratio between the cylinder and the sphere that affects performance. A shorter cylinder length compared to the sphere length affects velocity and alignment performance.

[00048] A venturi allows a smooth transition from a larger orifice to a smaller one. This transition minimizes flow transitions and thus reduces system constraints. The transition minimizes energy loss and supports fiber alignment.

[00049] The transition in a venturi is extremely difficult to create in a production tooling environment. As a result, using the geometric properties of a sphere or similar shape allows the ability to obtain many of the properties of the venturi effect using standard production practices.

[00050] All points on a sphere are equidistant from a fixed point. Contours and plane sections of spheres are circles. Spheres have the same width and circumference. Spheres have maximum volume with minimum surface area. All the above properties allow the meat to flow with minimal interruptions. There is no static or dead zone. No matter at what angle the cylinder intersects the sphere, the cross-section is always a perfect circle.

[00051] It is an object of the present invention to increase meat speed by forcing linear fiber alignment. Petition 870220092174, dated 07 / 10 / 2022, page 24 / 41 14 / 28

[00052] It is an object of the present invention to have spherical geometry or a similar shape in orifice plate or grinder plate openings to create venturi effects.

[00053] The present invention relates to a grinding assembly having a feed hopper in which the material to be ground is placed. The grinding assembly further comprises a grinder portion, including a grinding head, a mounting ring 310, a bridge, a collection tube 16, a drill or feed screw, and a barrel. A feed screw is located in the grinding head to advance the material in the feed hopper through the head. A knife assembly is mounted on the end of the feed screw and rotates with the feed screw in combination with the hole plate / grinder plate 14. This grinds the material that is promoted towards the hole plate / grinder plate 14 by the feed screw. The feed screw has a hole at its downstream end into which a central pin is inserted.The central pin extends through a central passage of the knife assembly and through a bushing that is positioned in a central opening of the grinder plate or orifice plate 14. A collection cone is located downstream of the grinder plate / orifice plate 14 and is attached to the bushing. The orifice plate / grinder plate 14 consists of an outer section with a plurality of grinding openings 210 and an inner section with at least one collection passage. The collection passage or passages of the orifice plate / grinder plate 14 lead to a collection structure defined by the collection cone, which generally includes a collection cavity and a discharge passage. A grinder plate / orifice plate guard is located downstream from the orifice plate / grinder plate 14 and holds the collection structure in place. A mounting ring 310 holds the guard against the orifice plate / grinder plate 14 and mounts the intervening structures to the grinding head body. Petition 870220092174, dated 07 / 10 / 2022, page 25 / 41 15 / 28

[00054] The present invention relates to a grinder head for a meat grinding assembly. The invention improves fiber alignment. The meat fiber is drawn through the holes in the grinder plate, which stretches the meat fiber. The venturi effect created by the hole aligns the fiber across the plate. The meat fiber is stretched, allowing for a clean cut. There is little or no release of myosin.

[00055] It is an object of the present invention to obtain the smallest cross-section by cutting the meat.

[00056] It is an object of the present invention that the grinder grinds the food product.

[00057] This product flow is accelerated by using a system that reduces the size of the cylinder. Using Bernoulli's law equation AiVi=A2V2, the velocity is increased by reducing the cross-sectional area.

[00058] The typical way to accomplish this is by using a venturi nozzle. However, a venturi requires a gradual reduction in area and a throat of finite length. Considering the plate thickness constraints, it was not feasible to place a state-of-the-art venturi in a grinder or orifice plate. However, by utilizing the properties of a sphere, the product achieves acceleration through the intersection of a cylinder with a sphere of larger diameter.

[00059] In a sphere, the pressure is equal in all directions. Therefore, when the sphere is intersected by a cylinder, the product will move in a direction coaxial with the cylinder at high speed. The impact on the product on the grinder plate is greater because the product moving at a higher speed will generate more momentum.

[00060] It is an object of the present invention to provide a venturi effect in the orifice plate / grinder plate openings by creating a sphere-to-cylinder opening. This creates a venturi effect or a venturi pump. This accelerates the product through the orifice. The spherical cut Petition 870220092174, dated 07 / 10 / 2022, page 26 / 41 16 / 28 creates equal pressure in all directions. It is an object of the present invention to have a spherical hemisphere or curved structure that has a diameter that is not greater than the flow blockage for the liquid, gas, or solid used and is not less than the diameter of the connected cylindrical portion.

[00061] It is an object of the present invention that the spherical hemisphere or curved structure has a diameter between 1.01 and 2.5 times larger than a cylindrical portion that intersects it. It is preferable to have a sharper edge from the rim to the hole.

[00062] It is an object of the present invention to use spherical geometry, with cylindrical intersections, and that the ratio of the diameter of the sphere divided by the area of ​​the cylinder is not greater than the flow blockage for the liquid, gas or solid used and is not less than the diameter of the connected cylindrical portion to create conditions for meat flow that maintain improved cellular structure.

[00063] Irregular shapes do not have diameters, but they do have areas. For a given ratio of a linear item, the ratio becomes the square of the linear ratio. For curved and irregular shapes, the ratio between the initial area and the reduced area is approximately 1.2 to 6.25.

[00064] It is an object of the present invention that the independently controlled speed blades are located on the outside and inside of the grinder plate.

[00065] It is an object of the present invention that the independently controlled speed blades are located inside the grinder plate.

[00070] It is an object of the present invention that the blade, as it wears, has less flexibility and remains in an upright position. It is the tension caused by the bending of the blade that causes this. It is an object of the present invention to continuously bring a sharp edge of the blade into contact with a shear surface. This will continue until there is no more space between the blade and the blade holder. It is an object of the present invention that the pressure on the blades is caused by fasteners.

[00071] It is an object of the present invention that the blade is used with a grinding assembly in the ground meat industry. It is an object of the present invention that three blades are used per blade / knife retaining ring. It is an object of the present invention that at least two blades are used per ring.

[000145] The present invention relates to fiber orientation technology. Fiber orientation technology reduces pressure across the entire grinder plate, aligning the meat fibers so that the muscle fiber contraction occurs in a chosen direction, controlling both bite and shrinkage. Fiber orientation technology provides less resistance to product flow. [000146] Fiber orientation technology provides a better shearing surface for a cleaner cut. Fiber orientation technology aligns the fibers on the grinder plate so that the shearing action disrupts as few muscle cells as possible. Fiber orientation technology reduces the total area of ​​the grinder plate by blocking the flow of meat, resulting in less change of direction for the meat processing product. Fiber orientation technology pulls the meat fiber through the openings of the grinder plate, rather than pushing it, using the principles of the locking / venturi plate. Petition 870220092174, dated 07 / 10 / 2022, pp. 37 / 41 27 / 28 [000147] All these fiber guidance technology features reduce the release and mixing of myosin with actin, the net effect is controlled fiber guidance, less myosin activity resulting in better bite / binding and control over the final shape of the food. [000148] Spherical geometry in grinder plate openings creates venturi effects. [000149] The grinder plate has a multiplicity of filling holes distributed in a predetermined pattern. The holes consist of spherical portions or a curved structure intersecting a cylindrical portion. The spherical portion or curved structure has a diameter that is not larger than the flow blockage for the liquid, gas, or solid used and is not less than the diameter of the connected cylindrical portion. By reducing the cross-sectional area, a venturi condition is created. When using spherical portions or a curved structure, intersections between the cylinder and the spheres or curved structures create transitions that can be manufactured whose geometry approximates a venturi-style system. It is preferable to have a sharper edge from the rim to the hole. To obtain a perfect edge, it is preferable to sharpen it with a grinder. In a preferred embodiment, the grinder plate is chrome-plated. [000150] By using the principles of conservation of mass and conservation of energy, the volumetric flow rate must be equal at all points in the system. (piAiVi) = (p2A2V2). Since p is a constant, velocity is inversely proportional to the cross-sectional area. Furthermore, a venturi requires a ramp of some finite distance and a throat that also has a finite distance. [000151] A spherical geometry feeding a circular cross-section that creates an increased product velocity, Petition 870220092174, dated 07 / 10 / 2022, pp. 38 / 41 28 / 28 maintaining more consistent pressure on the meat. A sphere has the following properties: All points on a sphere are equidistant from a fixed point. The contours and plane sections of spheres are circles. The spheres have the same width and circumference. Spheres have maximum volume and minimum surface area. All the properties allow the meat to flow with minimal interruption. There are no static or dead zones. No matter at what angle the cylinder intersects the sphere, the cross-section is always a perfect circle. Pressure inside a sphere is uniform in all directions. [000152] When meat is passed through a circular cross-section of a sphere, the fact that the pressure is uniform on the sphere creates forces that are coaxial with the sphere. The reduction in area accelerates the meat through the cylinder of the filling plate. The acceleration has been empirically shown to align the fibers in the primary direction of flow. Therefore, there is fiber orientation. Petition 870220092174, dated 07 / 10 / 2022, pp. 39 / 41
