Description

Technical Field

[0001] This invention belongs to the technical field of meat processing equipment, specifically relating to a pressure control device and method for a meat grinder and cutter. Background Technology

[0002] As a common meat processing equipment, the meat grinder / cutter uses the axial thrust generated by the rotation of the screw conveyor (auger) to continuously push the meat fed into the hopper forward. At the end of the conveying process, the drive shaft, rotating blade, and fixed perforated plate are arranged sequentially along the axial direction. Through the relative shearing motion between the blade and the perforated plate, the meat is repeatedly cut and squeezed until it is extruded through the perforated plate, ultimately forming uniformly sized minced meat.

[0003] However, in actual processing, due to the inherent gap between the auger and the inner wall of the feed cylinder, when meat fibers are caught or stuck in this gap, it triggers a violent mechanical pulling effect. This pulling effect leads to excessive breakage of muscle fibers and tissue damage, resulting in a significant reduction in the microstructural integrity of the minced meat and the final product quality.

[0004] Therefore, there is an urgent need to provide a device and corresponding method for effectively regulating the internal pressure of a meat grinder / cutter. Summary of the Invention

[0005] The purpose of this invention is to provide a pressure control device and method for a meat grinder and cutter, which can provide counterweight and compression measures to reduce meat jamming, avoid violent mechanical pulling and the excessive breakage and tissue damage caused by it, and solve the problem of reducing the microstructure integrity of meat and the quality of the final product.

[0006] The specific technical solution adopted by this invention is as follows: A pressure regulating device for a meat grinder and cutter includes a cabinet and a feed pipe, an auger, and a discharge pipe arranged vertically along the cabinet. The cabinet contains a drive assembly for providing power to cut the meat inside the discharge pipe. The device also includes: The extrusion feeding assembly is located outside the cabinet; The extrusion feeding assembly includes a handle, a first threaded interface, and a counterweight cylinder connected vertically along the cabinet. The handle is used to drive the counterweight cylinder to insert into the feed pipe, so that the counterweight cylinder provides pressure to the meat material that crosses the gap between the feed pipe and the auger cylinder, thereby reducing the jamming of the meat material.

[0007] As an optional solution, a first or second counterweight is inserted inside the counterweight cylinder to increase the pressure on the meat. The first counterweight is distributed in a straight line along the axial direction of the counterweight cylinder, and the second counterweight is distributed in a circular array around the central axis of the counterweight cylinder.

[0008] As an optional solution, the bottom of the counterweight cylinder is provided with a through hole and an elastic buffer pad, and the elastic buffer pad is integrally provided with a protrusion extending into the through hole; The second counterweight extends into the through hole and abuts against the protrusion. The protrusion, when deformed toward the open through hole, is used to reduce the stress inside the elastic buffer pad, thereby improving the uniformity of the meat extrusion by the elastic buffer pad.

[0009] As an optional solution, a storage tank and a limiting plate are installed on the top of the cabinet; The bottom of the storage tank is connected to the top of the feed pipe, and the limiting plate has a round hole in the middle for limiting the extrusion feeding assembly.

[0010] As an optional solution, the auger cylinder is provided with a drive shaft, a hollow cylinder, a spiral blade and an auger connected to the drive assembly in sequence along its axial direction inside the cylinder; The spiral blades are spirally arranged around the hollow cylinder and partially exposed at the opening of the feed pipe.

[0011] As an alternative, the spacing of the helical blades decreases gradually along the central axis of the hollow cylinder toward the auger, and the outer diameter of the helical blades increases gradually along the central axis of the hollow cylinder toward the auger.

[0012] As an optional solution, a flange and a connecting shaft are sequentially welded to the end of the drive shaft along its axial direction, and an elastic element and a sealing ring are provided at intervals between the flange end face and the root of the spiral blade; The sealing ring surrounds the elastic element and serves to separate the elastic element from the meat.

[0013] As an alternative, the drive assembly includes a motor, belt, drive shaft, and gear set disposed inside the cabinet, and the motor output provides power for cutting meat inside the discharge pipe through the belt, drive shaft, and gear set.

[0014] As an alternative, the discharge pipe has an annular boss welded inside, and a seat ring and a screen plate welded to the middle of the seat ring are inserted inside the boss. The seat ring is pressed tightly against the boss under the squeezing action of the auger cylinder, causing the meat inside the auger cylinder to be squeezed out along the screen holes of the screen plate.

[0015] A method for regulating the pressure of a meat grinder / cutting machine, using the pressure regulating device for a meat grinder / cutting machine as described above, includes the following steps: Start the drive assembly, set the rotation speed, and make the thrust inside the auger reach the preset range; The pre-prepared meat pieces are placed one by one into the feed pipe, and the extrusion feeding assembly is held to squeeze the meat pieces downwards; Release the extrusion feeding assembly and apply pressure to the meat using the weight of the extrusion feeding assembly. This provides pressure to the meat that crosses the gap between the feed pipe and the auger cylinder, reducing the amount of meat stuck. The interval between the auger and the discharge pipe is used to cut the meat by the power provided by the drive assembly; The cut meat is discharged along the discharge pipe.

[0016] The technical effects achieved by this invention are as follows: This invention provides counterweight and compression measures during the meat grinding process to reduce meat jamming, avoid severe mechanical pulling and the resulting excessive breakage and tissue damage, and solve the problem of reducing the microstructural integrity of meat and the quality of the final product.

[0017] This invention, during the meat grinding process, prevents meat from getting stuck while allowing for controllable and adjustable extrusion area of ​​the meat by adjusting the number and position of counterweights.

[0018] In the process of mincing meat, this invention adjusts the shape and structure of the blade so that the blade, in conjunction with the deformation movement of the elastic element, can deflect a certain distance when the resistance of the meat exceeds a preset upper limit, thereby opening the cutting gap and further reducing the degree of meat jamming.

Detailed Implementation

[0021] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0022] Example 1:

[0023] like Figures 1-13As shown, a pressure regulating device for a meat grinder and cutter includes a cabinet 1 and a feed pipe 2, an auger cylinder 4, and a discharge pipe 6 arranged vertically along the cabinet 1. An extrusion feeding assembly 3 is provided outside the cabinet 1, and a drive component 5 for providing power for cutting meat inside the discharge pipe 6 is installed inside the cabinet 1. During production, the cabinet 1, feed pipe 2, extrusion feeding assembly 3, auger cylinder 4, and discharge pipe 6 are all made of food-grade alloys, such as food-grade 304 stainless steel or 316 stainless steel.

[0024] During operation, the operator starts the drive assembly 5, uses one hand to put the pre-cut meat pieces one by one into the feed pipe 2, and uses the other hand to hold the extrusion feeding assembly 3 to squeeze the meat pieces downward. The extrusion feeding assembly 3 can be released, and the pressure of the extrusion feeding assembly 3 on the meat pieces is applied by its own weight. This provides pressure to the meat pieces that cross the gap between the feed pipe 2 and the auger cylinder 4, reduces the jamming of the meat pieces, and allows the meat pieces to travel along the auger cylinder 4 and the discharge pipe 6 and be cut into granules.

[0025] See attached document Figure 1 , Figure 3 and Figure 8 The extrusion feeding assembly 3 includes a handle 301, a first threaded interface 302, and a counterweight cylinder 303 connected vertically along the cabinet 1. The handle 301 is used to drive the counterweight cylinder 303 to insert into the feed pipe 2, so that the counterweight cylinder 303 provides pressure to the meat material that spans the gap between the feed pipe 2 and the auger cylinder 4, reducing the jamming of meat material. The pressure can be increased without the need to add electrical equipment, which can control the manufacturing cost and electricity cost of the device. It can also free the operator's hands and make it convenient to pick up the meat material later.

[0026] See attached document Figure 1 , Figure 3 and Figure 4 The top of the cabinet 1 is equipped with a storage tank 101 and a limiting plate 304 set at the opening of the storage tank 101. The bottom of the storage tank 101 is connected to the top of the feed pipe 2. When feeding, the operator piles the meat into the storage tank 101 and then puts it into the feed pipe 2 one by one by hand. In addition, the limiting plate 304 has a round hole in the middle for limiting the extrusion feeding assembly 3. After the operator puts in the meat, he can put down the extrusion feeding assembly 3 along the round hole to apply pressure to the meat.

[0027] It should be noted that the handle part 301 is cylindrical at one end and the cylindrical end is disc-shaped. The diameter of the disc is larger than the diameter of the hole. When the disc is supported by the limiting plate 304, the counterweight cylinder 303 descends to the lower limit to prevent it from falling entirely into the feed pipe 2.

[0028] See attached document Figure 4 , Figure 5 and Figure 8The counterweight cylinder 303 is equipped with a first counterweight 305 for increasing the pressure on the meat. For example, each first counterweight 305 weighs 2kg. Depending on the size of the meat, different numbers of first counterweights 305 are installed. For example, for 6kg of meat, two first counterweights 305 are configured. The two first counterweights 305 are arranged in a straight line along the axial direction of the counterweight cylinder 303. After releasing the hand, the meat is automatically pressed down by the counterweight cylinder 303 without the need for continuous manual pressing.

[0029] As an optional embodiment, refer to the appendix Figure 4 , Figure 5 and Figure 9 The first counterweight 305 is replaced by the second counterweight 306. For example, each second counterweight 306 weighs 3kg. The second counterweights 306 are arranged in a circular array around the central axis of the counterweight cylinder 303. When the handle part 301 and the counterweight cylinder 303 are tightly connected through the first threaded interface 302, the second counterweights 306 are clamped by the handle part 301 and the counterweight cylinder 303 and can press the meat with the counterweight cylinder 303 without continuous pressing by hand. Taking 9kg of meat as an example, two second counterweights 306 can be configured, or the number of second counterweights 306 can be increased to three.

[0030] See attached document Figure 4 , Figure 7 and Figure 9 The bottom of the counterweight cylinder 303 is provided with a through hole 307 and an elastic buffer pad 308. The elastic buffer pad 308 is integrally provided with a protrusion 309 extending into the through hole 307. During installation, both the elastic buffer pad 308 and the protrusion 309 are made of food-grade silicone material and are fixed to the bottom of the counterweight cylinder 303 by an integrated hot melt method or adhesive method. In use, the operator extends the ends of a specified number of second counterweights 306 into the through hole 307 and abuts against the protrusion 309, so that the weight of the second counterweights 306 acts along the protrusion 309 on the entire elastic buffer pad 308, which can apply pressure to the meat covered by the elastic buffer pad 308. The elastic buffer pad 308 deforms under pressure and can conform to the shape of the gap between the feed pipe 2 and the auger cylinder 4, further reducing the jamming of meat. When the elastic buffer pad 308 is subjected to a reaction force from the meat material exceeding a set threshold, the protrusion 309 deforms toward the open through hole 307 under the stress of the elastic buffer pad 308, which can reduce the stress inside the elastic buffer pad 308 and make the elastic buffer pad 308 fit the shape of the feed pipe 2 and the auger cylinder 4, thereby improving the uniformity of the elastic buffer pad 308 in squeezing the meat material.

[0031] This invention, by using a counterweight cylinder 303 in conjunction with a first counterweight 305 or a second counterweight 306, reduces the jamming of meat materials, avoids severe mechanical pulling and the resulting excessive breakage and tissue damage, and solves the problem of reducing the microstructural integrity of meat materials and the quality of the final product.

[0032] As an optional embodiment, by increasing the number of second counterweights 306, the number of through holes 307 for the deformation of the protrusions 309 will decrease, thereby reducing the degree of deformation of the elastic buffer pad 308 along the axial direction of the counterweight cylinder 303, and causing the elastic buffer pad 308 to deform radially along the counterweight cylinder 303, covering a larger area of ​​meat. Conversely, by reducing the number of second counterweights 306, the operator can concentrate the elastic buffer pad 308 along the axial direction of the counterweight cylinder 303, reducing the area of ​​meat it covers, thus achieving controllable and adjustable area of ​​meat compression.

[0033] See attached document Figure 5 , Figure 7 and Figure 13 Inside the auger cylinder 4, along its axial direction, there are sequentially arranged a drive shaft 401, a hollow cylinder 406, a spiral blade 407, and a cutter 408 connected to the drive assembly 5. During installation, the drive shaft 401 is passed through the inside of the auger cylinder 4 into the inside of the cabinet 1 and connected to the drive assembly 5. The hollow cylinder 406 is sleeved on the end of the drive shaft 401 through a connecting shaft 404, and the hollow cylinder 406 is keyed to the connecting shaft 404, so that the drive shaft 401, the connecting shaft 404, and the hollow cylinder 406 can rotate synchronously under the power of the drive assembly 5. In addition, the spiral blade 407 is welded to the outer wall of the hollow cylinder 406, and the cutter 408 is fixed to the outer wall of the hollow cylinder 406 with screws. During operation, the meat enters the auger cylinder 4 along the feed pipe 2. Since the spiral blades 407 surround the hollow cylinder 406 in a spiral shape and are partially exposed at the opening of the feed pipe 2, the meat is pushed by the spiral blades 407 and moves axially along the hollow cylinder 406 towards the discharge pipe 6 until the meat contacts the auger 408, thereby the auger 408 cuts the meat into granules.

[0034] See attached document Figure 5 , Figure 7 and Figure 13 The spacing of the spiral blades 407 decreases gradually along the central axis of the hollow cylinder 406 toward the auger 408, and the outer diameter of the spiral blades 407 increases gradually along the central axis of the hollow cylinder 406 toward the auger 408. As the meat travels along the axial direction of the hollow cylinder 406, the space for the meat to move is expanded, further reducing the amount of meat stuck.

[0035] See attached document Figure 7 , Figure 11 and Figure 12The 408 auger has a central ring and multiple blades integrated on the outer side. The blades are inclined relative to the central ring, and the back of the blades has a clearance groove. After the blades cut the meat, the remaining meat can enter the clearance groove and be cut by the next blade, thus maintaining the continuity of meat cutting.

[0036] See attached document Figure 5 , Figure 6 and Figure 7 A flange 403 and a connecting shaft 404 are sequentially welded to the end of the drive shaft 401 along its axial direction. An elastic element 405 and a sealing ring 409 are welded (or bonded) between the end face of the flange 403 and the root of the spiral blade 407. During installation, the sealing ring 409, based on food-grade rubber, closes the space between the end face of the flange 403 and the root of the spiral blade 407 to form a sealing cavity. This allows the sealing ring 409 to surround the elastic element 405 and separate the elastic element 405 from the meat, preventing the meat from contacting the elastic element 405 and causing jamming. When the resistance of the meat material to the auger 408 exceeds the preset upper limit, the auger 408 drives the hollow cylinder 406 and the spiral blade 407 to move forward, slide along the connecting shaft 404 and squeeze the elastic element 405. The elastic element 405, which is based on the air spring, is compressed and its own elastic potential energy increases, causing the auger 408 to shift a certain distance, opening the cutting gap and reducing the degree to which the auger 408 is stuck with meat material. When the auger 408 detaches from the meat, the elastic element 405 recovers its deformation under the action of its own elastic potential energy, pushing the auger 408, hollow cylinder 406 and spiral blade 407 to reset.

[0037] See attached document Figure 3 , Figure 4 and Figure 5 The drive assembly 5 includes a motor 501, a belt 502, a drive shaft 503 and a gear set 504 disposed inside the cabinet 1. During installation, the motor 501 is fixed inside the cabinet 1 by bolt and nut assembly, the drive shaft 401 is rotatably mounted inside the cabinet 1 by sealed bearing 402, and the drive shaft 503 is rotatably mounted inside the cabinet 1 by bearing seat. During operation, the output end of motor 501 drives transmission shaft 503 to rotate via belt 502 and two pulleys. Transmission shaft 503 drives drive shaft 401 to rotate via gear set 504, thereby driving hollow cylinder 406, spiral blade 407 and auger 408 to rotate, providing power for cutting meat inside discharge pipe 6.

[0038] See attached document Figure 7 , Figure 10 and Figure 11The discharge pipe 6 is detachably connected to the auger cylinder 4 via the second threaded interface 604. The discharge pipe 6 has an annular boss 601 welded inside. A seat ring 602 and a screen plate 603 welded to the middle of the seat ring 602 are inserted inside the boss 601. During installation, the seat ring 602 is pressed tightly against the boss 601 under the squeezing action of the auger cylinder 4, so that the screen plate 603 is stably suspended at the outlet of the discharge pipe 6. During operation, part of the meat enters the screen holes of the screen plate 603 under the pushing action of the spiral blade 407 and is cut by the auger 408 until another part of the meat enters the screen holes of the screen plate 603 and is squeezed out, thus realizing automatic feeding.

[0039] Example 2:

[0040] like Figure 14 As shown, a pressure control method for a meat grinder / cutter uses the pressure control device for a meat grinder / cutter as provided in Embodiment 1. The pressure control method includes the following steps: Power on: Start drive component 5, set the speed, and make the thrust inside the auger cylinder 4 reach the preset range; Feeding: Use one hand to put the pre-cut meat pieces into the feed pipe 2 one by one, and use the other hand to hold the extrusion feeding assembly 3 to squeeze the meat pieces downwards; Automatic extrusion: Release the extrusion feeding assembly 3, and use the weight of the extrusion feeding assembly 3 to apply pressure to the meat, providing pressure to the meat that crosses the gap between the feed pipe 2 and the auger cylinder 4, reducing the jamming of meat; When the handle part 301 and the counterweight cylinder 303 are tightly connected through the first threaded interface 302, the second counterweight 306 is clamped by the handle part 301 and the counterweight cylinder 303, and can press the meat with the counterweight cylinder 303 without continuous pressing by hand. Taking 9kg of meat as an example, two second counterweights 306 can be configured, or the number of second counterweights 306 can be increased to three. At the same time, the elastic buffer pad 308 deforms under pressure, which can fit the shape of the gap between the feed pipe 2 and the auger cylinder 4, further reducing the jamming of meat. Cutting: The interval between the auger cylinder 4 and the discharge pipe 6, under the power provided by the drive assembly 5, cuts the meat. Feeding: The cut meat is discharged along the discharge pipe 6.

[0041] The above description is merely an optional embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
