Background
U.S. Pat. No. 4,205,415 relates to a conical nozzle that slightly squeezes a frozen ground meat mass to form a coherent mass while maintaining the ground meat stream in an elongated crumb-like shape to aerate the coherent mass. A positive displacement pump forces the meat through a capstan and then through a mouth to a rotating involute knife to form a patty of frozen ground meat in a continuous process.
Us patent No. 4,479,614 relates to a meat grinder comprising a pump which feeds meat particles into a mixing chamber at a constant flow rate. The meat exits into a collection chamber of frusto-conical shape for passage to the capstan. A rotary knife with radially extending blades is rotated at variable speeds by a hydraulic motor. The variable flow rate of particles to the chamber and the variable speed of the knife results in a variable particle size output by the capstan.
U.S. patent No. 3,986,227 relates to a printing system for toner copy paper where the toner is melted by a nip formed by a hot roll and a backing roll. The scraping blade engages the destructible surface of the backup roll at a critical angle selected by the coefficient of friction between the backup roll surface and toner debris contaminants collected on the backup roll surface. Thus, the blade slides freely on the rolling surface, but does not slide on the surface of the contaminant film. The film forms a locking angle with the blade, puts the blade in stress, and creates a chisel-like film removal action.
U.S. Pat. No. 4,184,429 relates to a doctor blade for wiping excess ink from the printing surface of a print, and methods for making doctor blades and printing devices. The blade includes a body having a constant blade thickness between parallel blade surfaces and an edge tip portion adjacent the blade body having a shaped blade bevel substantially equal to a run-in blade bevel of a wedge blade. Throughout the tip portion, the doctor blade has a contact tip thickness equal to the height of the formed blade bevel. As a result, during an excess ink wiping operation, the effective area of the shaped blade bevel remains constant at an optimum dimension despite progressive wear of the edge blade tip portion in the direction of and throughout the useful depth.
Us patent No. 4,257,343 relates to the coating of a strip of material that passes over a support member that forms one of the closed surfaces of a closed cavity. The closed chamber operates under vacuum conditions. The coating liquid is supplied to the closed chamber in excess to form a layer on the surface of the strip. At the end of the coating action, when the strip leaves the closed chamber, it is contacted by a movably positioned blade which provides a wiping action on the strip to remove excess coating liquid. The vacuum in the closed chamber forces the blade against the strip. Thus, by varying the vacuum, the amount of coating liquid adhering to the strip leaving the closed chamber is varied.
U.S. Pat. No. 4,782,756 relates to a print roller ink cap remover with a solid ink transfer roller. The present invention includes a plurality of side-by-side scraping blades that selectively engage the roller to remove transferred ink. A separate ink collector roller receives the removed ink and is wiped clean by a single doctor blade which deposits the ink in a disposable liner in the underlying pan. The separate blade is placed in its scraping position manually or pneumatically or electrically driven.
Us patent No. 7,796,913 relates to a cleaning station for removing particles from a moving sheet in use in an electrophotographic printer/copier which includes a sheet cleaning device having a support carriage shoe assembly (shoe assembly). The board cleaner has two eraser blades, including one or more shaped metal blades, each having a differentiating section that distinguishes one eraser blade from the other.
U.S. Pat. No. 7,930,830 relates to a scraping tool with retractable safety guard for removing debris and dust from glass and tile. The scraping tool includes a housing formed of two separate parts and a guard member, the housing being adapted to retain a single or double sided blade between the housing parts. Within the housing, the scraping blade is fixed in a rigid, stationary position by a plurality of posts.
U.S. patent No. 8,024,835 relates to a method and tool operable for treating a substance associated with a surface of an object or body, having a first treatment tool and a second support tool. The processing tool has a rigid holding portion and a processing portion and is manufactured as a single unitary tool. The post extends in the cantilever beyond the retention portion to support the resilient and flexible blade, held at a torsional angle relative to the handle. The blade is configured for controlled deflection about the post when a vertical force exceeding a predetermined force is encountered to prevent damage to the surface or damage to an object. To facilitate use of the tool, the holding portion and the treatment portion are disposed in an angular spatial relationship to each other. The support tool supports the object during processing.
U.S. patent No. 8,086,133 relates to a cleaning station for removing particulate material from a moving plate in an electrophotographic printer/copier that includes a plate cleaning device having a support shoe assembly. The board cleaner has two eraser blades, including one or more blades, each of which has a differentiating portion that distinguishes one eraser blade from the other eraser blade when the blades are locked into the cleaner sump by a spring.
U.S. patent No. 8,401,446 relates to a printing apparatus and method that includes a charging device positioned adjacent to a photoreceptor that charges a latent image onto the photoreceptor. A transfer assist blade is adjacent the photoreceptor that presses the media sheet against the photoreceptor to cause the marking material to transfer to the media sheet. The apparatus also includes a controller operatively connected to the transfer assist blade. The controller causes the transfer assist blade to apply a greater pressure to the leading portion and the trailing portion of the media sheet relative to the middle portion of the media sheet.
In the prior art, conventional meat grinders have utilized a screw-type conveyor for advancing the meat particles through the cavity to force them through a capstan disposed at the end of the cavity. The capstan typically has a plurality of holes disposed therethrough for reducing the size of the meat particles. Typically, mincing the meat begins with a baseball-sized piece of meat and then reduces to the desired size, which can take multiple mincing stages.
The screw-type meat grinder requires a predetermined gap between the screw conveyor and the face of the cavity through which the meat passes. This gap allows the screw conveyor to rotate while cleaning the walls. However, this gap 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 at the capstan. This pressure limit defines the maximum flow velocity of the meat that can pass through the capstan. In addition, cartilage or bone debris that may be present in the meat may block the winches and further prevent mincing.
In a large scale manufacturing environment, it is necessary to replace the winch at different stages of operation in mincing the meat to the desired particle size. Since it is very difficult to go from large particle sizes to very small particle sizes, multiple stages are required. As the meat exits the capstan, it exhibits a very "sticky, stringy" texture, as the fat and meat fibers tend to stick together in the longitudinal direction. Therefore, the mincing operation requires an additional step to reduce the length of the material. All these operations must be repeated for each mincing stage.
The meat industry has attempted to control fiber length during the production process through a variety of designs. The best previous method is a bowl chopper, which is a batch system that slows down production, under the control of the operator.
The meat grinder does not shear the fibers to a specific length. The meat grinder uses hydraulic pressure to force the product out of the meat through the apertures, and the inner grinding blades are cleaners that clean the apertures of the material into which they can be inserted. The extrusion process does not control the degree of fiber, which subjects the product to very high pressures and does not achieve the desired product quality. In the prior art, even if the inner mincing blades were able to operate at a designed speed to cut the fibers to a desired length, it would not be possible to stretch the meat and align the fibers at this stage of manufacture.
Current forming techniques rely on high pressure, velocity, and complex material flow paths, which produce inadequate product quality. High pressure is applied to the meat cells, and the greater the pressure, the more massaging, squeezing and turbulence occurs to the meat cells. The high velocity, together with the complex flow path, increases pressure and turbulence and acts on the meat product, releasing and mixing myosin/actin from the cells, causing the muscle fibers to stick together and contract (protein binding). This shrinkage occurs during high heat application (as in cooking). The effect of the meat fiber is to contract the length, which together with the protein not only shortens the muscle fiber, which if left uncontrolled, causes a strange cooking shape, but also a rubbery texture that is difficult to bite.
In muscle, actin is the main component of filaments, which together with motor protein myosin (which forms thick filaments) form myofibrillar actomyosin. These fibers constitute the mechanism of muscle contraction. Using ATP hydrolysis as energy, the curdlan head undergoes a cycle of: in this cycle, they attach to the filaments, apply tension, and then, depending on the load, perform a power stroke (power stroke), which causes the filaments to slide through, shortening the muscle.
Myofibrillar structures measure from microns to several millimeters in length. These fibrous structures are bundled together to form muscles. Myofibrillar proteins are the largest group and are known more about these proteins than other proteins. In muscle cells, actin is the scaffold on which myosin generates the force to support muscle contraction. Myosin is the major protein extracted from muscle cells by mechanical means.
An important purpose of tumbling and massaging is to solubilize and extract myofibrillar proteins to produce a protein extrudate on the surface of the meat fibers. Upon heating, the extrudate bonds the shaped pieces together. As massage or mixing time increases, the bond strength also increases. This is due to the increased extrudate formation on the surface of the meat. Tropomyosin extrudates increased with increasing mixing time.
Mincing/chopping utilizes the concept of rupturing cells to release proteins. The mechanical chopping or shearing occurs at the shear/fill plate holes. This process extracts actin and myosin from muscle cells.
Mixing, utilizing friction and kinetic energy to release the protein extrudate. The shape and spacing of the filling holes may cause dead spots and turbulence in the flow of the meat. The change of direction is in the form of mixing and massaging. This is another process of extracting actin and myosin from muscle cells.
Massage, using friction, kinetic energy and pressure to augment the protein extrudate. This effect occurs almost anywhere the meat is in contact with the processing equipment, moved or redirected via pressure. This is also a process involving the extraction of actin and myosin from muscle cells.
The meat patty comprises whole muscle, cut meat (table trimming), or LFTB (fine-cut lean beef), or a combination thereof.
The mincer/mixer mixes the product into coarse ground meat or fine ground meat that produces the final product. This produces a homogeneous mixture formed into a noodle-like shape.
In the case of frozen food products, a slicer may be used which first slices the frozen food product and then minces the frozen food product in a mincer/mixer/blender.
Disclosure of Invention
The present application relates to holes machined into the capstan that form the direction of the fibers of the meat and stretch the fibers of the product. The object of the invention is to pass the fibres through the holes at a relatively high speed while aligning and stretching so that the fibres are sheared to the desired length.
The object of the present invention is to install a set of independent speed controlled blades on the outside of the capstan. The object of the invention is to use holes (holes made) to control the fibre direction. The present invention is directed to a grinder machine to extrude product, accelerate the product through a hole, which brings alignment and stretching of the fibers and allows the outer blades (outside blades) an opportunity to shear the fibers to any desired length. The only point for shearing the fibers is to place the fibers in stretched alignment at the exit of the orifice. It is an object of the present invention to have independent sets of blades with controllable speed to allow control of fiber length.
The present invention relates to a self-contained knife assembly with variable speed control for shearing fibers affected by the hole.
It is an object of the present invention to provide an outward (outboard) or outer knife (outer knife) assembly for a grinding machine.
It is an object of the present invention to provide an outward or outboard knife assembly for a filling machine, or any meat extrusion machine or apparatus thereof.
It is an object of the present invention to provide independent speed control of the outward or outboard knife assemblies. It is an object of the present invention that the device be hydraulically powered, electrically powered, pneumatically powered or powered by any other energy transmission system.
It is an object of the present invention that the knife rotating drum has a gear drive, belt drive, chain drive, or transmits energy to the knife rotating drum in any other way.
The object of the invention is that the device is attached via: threads, slip joints with retaining pins, clamping rings (as present in the figures), interrupted threads, flanges with bolts, a "U" shaped slip seat (slip socket) with locking cams or bolts.
The aim of the invention is that the knives used are of standard ready-made configuration. The object of the invention is that the knife is redesigned as required for different applications. It is an object of the present invention that the knife is a knife insert. The object of the invention is that the tool has a thickness equal to or smaller than the diameter of the hole. This will prevent the knife from closing the hole completely, thus stopping the flow and pulsing the meat.
During the start and stop of the meat flow, the cylindrical portion needs to be self-cleaning before the venturi effect can take place. It is an object of the invention that the spherical portion of the bore is shorter in length than the cylindrical portion or outlet of the bore.
It has been shown that there is a relationship between the length ratio between the spherical portion and the cylindrical portion. By proportionally longer spherical and shorter cylindrical sections, the venturi effect performs better when subjected to start-up or stop-action or pulse flow.
It is an object of the invention that the drum arrangement has a doctor assembly. The scraper assembly keeps the meat from rolling as in a clothes dryer, and removes the meat for a shorter time to contact the drum. Which guides the meat in a controlled manner and acts as a safety device in case the device is not properly mounted.
It is an object of the present invention that the drive portion of the knife ring utilizes three square notches with three raised lugs.
The invention includes an apparatus for mincing meat. The meat grinder includes a pump for pumping meat particles in a continuous flow under high pressure. The meat is pumped to the inlet of a collection chamber which is frusto-conical in shape and has an outlet of greater diameter. A capstan is disposed at the outlet of the collection chamber, the capstan having a plurality of holes disposed therein for reducing the particle size diameter of the meat as the meat is pressed through the holes. A cutting knife is disposed adjacent to the winch for reducing the length of particulate matter output from the winch. A variable motor is attached to the cutting knife for moving the cutting knife perpendicular to a surface in the winch. The variable motor has a variable speed to vary the length of particulate matter output by the winch according to the particular application.
According to another embodiment of the invention, the variable motor is a hydraulic motor having an external pump for providing hydraulic pressure thereto. The hydraulic motor has a continuously variable speed to rotate the cutting blade at a variable rotational speed. By varying the speed of rotation of the knife, the length of the particle size pressed through the capstan can be determined to the desired particle size.
In one embodiment, the grinder transports meat through the winch via its auger. The meat is cut again by an outer knife (outer knife). The rotational speed of the blade affects the fiber length. The speed may be adjusted via a speed control device connected to the motor. The motor drives the outer knife through a transmission that is mechanically connected from the input shaft to the outer drive hub. The contact of the outer knife with the capstan is adjustable by an outer knife pressure take-up ring assembly.
It is an object of the present invention to provide fiber orientation techniques to reduce the release and mixing of myosin and actin. The present invention is directed to fiber orientation techniques to control the direction of fibers. It is an object of the present invention that the fiber orientation technique provides less myosin activity, which results in better bite/bind (bind) and control of the final cooking profile.
The present invention relates to an apparatus and method for accelerating food products to stretch the product, aligning the fibers of the product. The object of the invention is to change the size of the holes or bores with vertical or concave walls from a larger diameter to a smaller diameter. It is an object of the invention that the wall has sharp edges. This principle has design similarities to a venturi. This refers to a nozzle, venturi, orifice, or restriction of flow that causes the product to accelerate and a corresponding pressure drop through the orifice.
By reducing the diameter of the tube through which the material passes, the velocity is increased. This is the law of conservation of mass. As the speed increases, the pressure of the material decreases. This is the law of conservation of energy.
For each liquid there is a ratio between the cross-sectional area (C) and the cross-sectional area (C), and the speed can only be increased by reducing the temperature or increasing the pressure. The same concept applies despite the minced meat non-homogeneous fluid. Unless there is a transition between the holes and the small holes have a defined length, it is not possible to obtain a venturi effect. The length ratio between cylinder and sphere affects performance. The shorter length of the cylinder compared to the length of the sphere affects the speed and alignment performance.
The venturi allows for a transition from a larger hole to a smaller hole. This transition minimizes fluid transitions and thereby reduces restrictions in the system. This transition minimizes energy loss and supports fiber alignment.
And difficulty in forming a transition in the venturi in a manufacturing tool environment. Thus, the ability to utilize the geometric characteristics of a sphere or similar shape allows for the ability to obtain a variety of venturi effect characteristics with standard product practice.
All points on the sphere are the same distance from the fixed point. The contour and cross-section of the sphere is circular. The spheres have the same width and circumference. The spheres have the largest volume with the smallest surface area. All of the above properties allow the meat to flow with minimal disruption. There are no quiescent zones or dead zones. No matter what angle the cylinder and the sphere meet, the cross section is always perfectly circular.
The object of the present invention is to increase the speed of the meat to force the linear fibers to align.
The object of the invention is to have a spherical geometry or similar in the capstan or orifice plate aperture to create a venturi effect.
The invention relates to a grinder having a hopper in which the material to be ground is placed. The grinder also comprises a grinder part which comprises a grinder head, a mounting ring, a bridge part, a collecting pipe, an auger or a supply screw and a barrel. The feed screw is located in the grinder head to advance material in the hopper through the grinder head. A knife assembly is mounted at the end of the feed screw and rotates with the feed screw and orifice plate/capstan. This minces the material advancing through the orifice plate/capstan via the feed screw. The feed screw has an aperture at its downstream end into which a central axial pin is inserted. The center pin extends through the central passage of the knife assembly and through a bushing located in the central opening of the capstan or orifice plate. The collection cone is located downstream of the orifice plate/capstan and is fixed to the liner. The orifice plate/capstan includes an outer section having a plurality of grinding apertures and an inner section having at least one collection channel. The collection channel of the orifice plate/capstan brings about a collection structure defined by a collection cone, which typically includes a collection chamber and a discharge channel. The orifice plate/capstan protection is located downstream from the orifice plate/capstan and holds the collection structure in place. A mounting ring secures the protector against the orifice plate/capstan and mounts the intervening structure to the body of the grinder head.
The present invention relates to a grinder head for a meat grinder. The present invention improves fiber alignment. The meat fiber is pulled through the holes of the capstan, which stretches the meat fiber. The venturi effect created by the holes aligns the fibers passing through the plate. The meat fibers are stretched and allow for clean cutting. Little or no actin release occurs.
The aim of the invention is to obtain a minimum section through the cutting of meat.
The present invention is directed to a grinder to grind a food product.
The product flow is accelerated by using a system that reduces the size of the cylinder. Equation A using Bernoulli's law1V1=A2V2The speed is increased by reducing the cross-sectional area.
A common way to accomplish this is to utilize a venturi nozzle. However, the venturi requires a gradual area decrease and a throat of defined length. Given the plate thickness limitations, it is not feasible to place the venturi of the prior art in a capstan or orifice plate. However, by taking advantage of the spherical nature, product acceleration is achieved by the intersection of the cylinder with a sphere of larger diameter.
In a sphere, the pressure is equal in all directions. Thus, when the sphere intersects the cylinder, the product will move at high speed in a direction coaxial with the cylinder. The impact on the product is greater in the winch since the product moving at higher speeds will generate more momentum.
It is an object of the present invention to provide a venturi effect in the aperture of an orifice plate/capstan by forming a sphere into a cylindrical aperture. This creates a venturi effect or venturi pump. This accelerates the product through the orifice. The cutting of the ball creates equal pressure in all directions. The object of the invention is to have a spherical hemisphere or curved structure with a diameter not larger than the restriction of the liquid, gas or solid used and not smaller than the diameter of the connected cylindrical part.
The object of the invention is a spherical hemisphere or curved structure having a diameter of 1.01 to 2.5 times the diameter of the cylindrical portion with which it intersects. Preferably with sharper edges from the edge to the hole.
It is an object of the present invention to use a sphere geometry with intersecting cylinders and the ratio of the diameter of the sphere divided by the area of the cylinder is no greater than the restriction of the liquid, gas or solid used and no less than the diameter of the connected cylinder part to create conditions for the flow of meat to maintain an improved cell structure.
The irregular shapes do not have a diameter, but they do have an area. For a given ratio of linear terms, the ratio is the square of the linear ratio. For curved and irregular shapes, the ratio of the initial area to the reduced area is from about 1.2 to 6.25.

The present invention relates to fiber orientation technology. The fiber orientation technique causes the pressure across the capstan to drop, aligning the fibers of the meat, and causing contraction of the muscle fibers to occur in a selected direction that controls biting and contraction. Fiber orientation technology provides less resistance to product flow.
Fiber orientation techniques provide a better shearing surface for cleaner cutting. The fiber orientation technique aligns the fibers on a capstan so that the shearing action ruptures as few muscle cells as possible. The fiber orientation technique reduces the total area of the capstan that blocks the flow of meat, which results in less directional change of the product acting on the meat. The fiber orientation technique pulls meat fibers through the apertures of the capstan instead of pushing with the venturi/spoiler principle.
All these features of the fiber orientation technique reduce release and mixing of myosin and actin, with the net result being controlled fiber orientation, less myosin activity, resulting in better bite/bind (bind) and better control of the final cooking profile.
The spherical geometry in the capstan's aperture creates a venturi effect.
The capstan has a plurality of fill holes distributed in a predetermined pattern. The bore includes a spherical portion or a curved structure intersecting a cylindrical portion. The diameter of the spherical portion or curved structure is not larger than the restriction (hook-flow) of the liquid, gas or solid used and not smaller than the diameter of the connected cylindrical portion. By reducing the cross-sectional area, a "venturi" condition is created. By utilizing a spherical portion or curved structure, the intersection between the cylinder and the sphere or curved structure forms a transition that can be made to approximate the geometry of a venturi-type system. It is preferred to have sharper edges from edge to hole. In order to obtain an excellent edge, it is preferable to sharpen it by a grinder. In a preferred embodiment, the capstan is coated with chromium.
Using the principles of conservation of mass and conservation of energy, the volumetric flow must be equal at all points in the system. (ρ)1A1V1)= (ρ2A2V2). Since ρ is a constant, the velocity is inversely proportional to the cross-sectional area. Also, the venturi requires some ramp of defined distance and a throat with defined distance.
The spherical geometry feeds into the circular cross-section which results in an increase in the speed of the product while keeping the pressure on the meat more consistent. The sphere has the following characteristics:
all points on the sphere are the same distance from the fixed point.
The contour and cross-section of the sphere is circular.
The spheres have the largest volume with the smallest surface area.
These properties allow the meat to flow with minimal disruption. There are no quiescent zones or dead zones.
No matter what angle the cylinder intersects the sphere, the cross-section is always perfectly circular.
The fact that the pressure is uniform in the ball as the meat passes through the circular cross-section of the ball creates a force that will be coaxial with the ball. The reduction in area accelerates the meat through the columns of the infill panel. It has been empirically shown that this acceleration aligns the fibers in the primary flow direction. Thus, there is fiber orientation.
