Description

Technical Field

[0001] The present invention belongs to the technical field of meat product processing, and specifically relates to a pretreatment device and a processing method for meat product production. Background Art

[0002] The pretreatment of meat product production is a key link to ensure product quality, safety and flavor, involving multiple processes such as raw material selection, cleaning, cutting, and marinating. In meat product processing, removing hair is an important step to ensure product hygiene and sensory quality, mainly including methods such as manual tweezers plucking, flame hair singeing, mechanical hair removal, and rosin glyceride hair removal.

[0003] A Chinese invention patent with the publication number of CN112493299B discloses a meat product pretreatment device, including: an outer cylinder, rollers circumferentially and evenly distributed inside the outer cylinder, and a driving mechanism for driving each roller to rotate in the same direction. Among them: inside the outer cylinder and between any two adjacent rollers, a guide shaft parallel to the rollers and driven by the driving mechanism to rotate in the same direction as the rollers is provided; a plurality of annular plates axially slidably assembled with the guide shaft are provided on the guide shaft, the middle area of the annular plate is recessed to form a recessed area, an elastic element connecting the two is provided between every two adjacent annular plates, and the elastic element is located in the recessed area; inside the outer cylinder and at both ends of any one guide shaft, a cam mechanism for driving the annular plates on the guide shaft to synchronously move closer to each other and press tightly in the middle is respectively provided. The present invention can perform hair removal at 360°, and there is no hair root residue in the livestock and poultry skin dehaired by this hair removal roller.

[0004] Traditional mechanical hair removal relies on friction or high-temperature burning, and can only remove epidermal hair, unable to destroy the hair follicle structure. The remaining hair roots are likely to appear in subsequent processing, affecting the product appearance and consumer experience. The unremoved hair follicles may breed microorganisms (such as Staphylococcus aureus), increasing the food safety risk; although chemical hair removal (such as the rosin method) can partially dissolve the hair follicles, there is a risk of excessive residue. Therefore, a pretreatment device and a processing method for meat product production are proposed. Summary of the Invention

[0005] To solve the problems raised in the above background art, the present invention provides a pretreatment device and a processing method for meat product production, which solves the problem that traditional mechanical hair removal relies on friction or high-temperature burning, can only remove epidermal hair, and is unable to destroy the hair follicle structure, and the remaining hair roots are likely to appear in subsequent processing.

[0006] To achieve the above object, the present invention provides the following technical solution: A pretreatment device for meat product production, including a support frame, a conveying device for conveying meat products is arranged on the support frame, and further includes:

[0007] A support seat, the support seat is fixedly installed on the top of the support frame;

[0008] A transmission assembly, which is arranged inside the support base;

[0009] A support assembly, which is arranged inside the support base;

[0010] A cleaning assembly, which is installed inside the support base;

[0011] Among them, the transmission assembly includes an output rod assembled inside the support base. Connecting rods are movably sleeved at both ends of the output rod. Arc-shaped plates are fixedly installed at both ends of the connecting rod. Arc-shaped guide rods are fixedly installed at both ends of the arc-shaped plate. A transmission convex block is fixedly installed at the top of the inner wall of the support base;

[0012] Second elastic members are sleeved at both ends of the connecting rod, and the second elastic members are connected between the arc-shaped plate and the output rod;

[0013] The support assembly includes a cross plate slidably arranged on the support base, and the bottom of the cross plate contacts the meat products conveyed by the conveying equipment.

[0014] Preferably, the top of one end of the cross plate is rounded, and the bottom of the arc-shaped plate is adapted to one end of the cross plate;

[0015] When the arc-shaped plate rotates to the bottom of the support base and the arc-shaped plate fits with the cross plate, the bottom of the arc-shaped plate is higher than the bottom of the cross plate.

[0016] Preferably, the two arc-shaped plates are connected by a stabilizing rod, and the stabilizing rod passes through the middle of the output rod;

[0017] The output rod drives the arc-shaped plate and the arc-shaped guide rod to rotate. The upper arc-shaped guide rod is guided by the transmission convex block, and the lower arc-shaped plate is pushed down by the connecting rod to contact the cross plate.

[0018] Preferably, the support assembly includes guide grooves opened on both sides of the support base for the cross plate to slide. Limit frames are fixedly installed on both sides of the support base. Guide rods are fixedly installed inside the limit frames. The cross plate slides on the guide rods through docking parts, and a reset elastic member for propping up the docking parts is arranged inside the limit frames.

[0019] Preferably, the guide grooves are inclined from the end close to the arc-shaped plate. The arc-shaped plate pushes the cross plate to move along the guide groove, so that the cross plate gradually disengages from contact with the arc-shaped plate.

[0020] Preferably, the cleaning assembly includes a first shunt pipe fixedly installed inside the support base. One end of the first shunt pipe is connected to a water injection device, and the other end of the first shunt pipe is movably sleeved with a first valve sleeve;

[0021] A water passing hole is formed in the first valve sleeve. A first cleaning pipe is connected to the outside of the first shunt pipe. Both ends of the first cleaning pipe are connected to the outside of the first shunt pipe, and the middle part of the first cleaning pipe is arranged inside the support seat and away from one end of the cross plate.

[0022] A water spraying hole is formed in the middle part of the first cleaning pipe.

[0023] Preferably, a first piston rod is fixedly installed at one end of the first valve sleeve. The first piston rod passes through the first shunt pipe, and a contact block is fixedly installed at one end of the first piston rod.

[0024] In the initial state, the inside of the first shunt pipe is communicated with the first cleaning pipe through the water passing hole. The arc-shaped plate contacts the cross plate, and the arc-shaped plate pushes the contact block, the first piston rod and the first valve sleeve so that the water passing hole does not coincide with the first cleaning pipe.

[0025] Preferably, a second shunt pipe is communicated with the bottom of the first shunt pipe. One end of the second shunt pipe is connected to the cross plate through a second piston rod.

[0026] A valve plug is sleeved inside the second shunt pipe, and an elastic cover for propping up the valve plug is arranged at one end inside the second shunt pipe.

[0027] In the initial state, the second cleaning pipe is blocked by the valve plug.

[0028] The present invention also provides a pretreatment method for meat product production, including the following steps:

[0029] S1. Place the meat product on the conveying equipment for conveying. The meat product sequentially passes through the bottom of the support seat, and the bottom of the cross plate contacts the meat product. The hair on the epidermis of the meat product will contact one end of the cross plate during the conveying process of the meat product.

[0030] S2. The driving motor drives the output rod, the arc-shaped plate and the arc-shaped guide rod to rotate. The upper arc-shaped guide rod is guided by the transmission convex block and pushes the lower arc-shaped plate to move downwards through the connecting rod and the stabilizing rod, so that the arc-shaped plate fits with the cross plate, and the hair on the epidermis of the meat product is clamped between the arc-shaped plate and the cross plate.

[0031] S3. The arc-shaped plate pushes the cross plate to move synchronously, thereby realizing the removal of the hair on the epidermis of the meat product.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0033] In the present invention, the output rod, the arc-shaped plate and the arc-shaped guide rod rotate. The upper arc-shaped guide rod is guided by the transmission bump, and through the connecting rod and the stabilizing rod, the lower arc-shaped plate is pushed downward to make the arc-shaped plate fit with the cross plate, clamping the hair on the surface of the meat product between the arc-shaped plate and the cross plate. Then, the arc-shaped plate pushes the cross plate to move synchronously, so as to realize the extraction of the hair on the surface of the meat product, effectively avoiding the exposure of the remaining hair roots in subsequent processing, reducing the food safety risk and improving the production quality of the meat product;

[0034] In the present invention, when the arc-shaped plate rotates to the lower end and contacts the cross plate, the first shunt pipe disconnects from the first cleaning pipe, and the water pressure in the first shunt pipe and the second shunt pipe gradually increases, thereby improving the stability of the cross plate. By increasing the water pressure, the pressure between the cross plate and the arc-shaped plate is increased to ensure the effect of hair extraction from the meat product. During the process of the arc-shaped plate pushing the cross plate to move, the water pressure in the second shunt pipe pushes the valve plug to compress the elastic cover, making the second cleaning pipe communicate with the second shunt pipe, and spraying water through the second cleaning pipe to clean the hair extracted between the cross plate and the arc-shaped plate;

[0035] In the present invention, water is injected into the first shunt pipe through the water injection device. The water in the first shunt pipe enters the first cleaning pipe through the water passing holes and is sprayed out from the middle of the first cleaning pipe. The water blows the hair on the surface of the meat product, and the hair fits on one end of the cross plate under the action of the water flow. When the arc-shaped plate contacts the cross plate, it is ensured that the hair of the meat product is located between the arc-shaped plate and the cross plate, which can improve the effect of hair cleaning of the meat product.

Specific embodiments

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] As Figures 1 to 8 shown, the present invention provides a pretreatment device for meat product production, including a support frame 1, on which a conveying equipment 6 for conveying meat products is arranged, and further includes:

[0047] A support seat 2, which is fixedly installed on the top of the support frame 1;

[0048] A transmission assembly 5, which is arranged inside the support seat 2;

[0049] A support assembly 4, which is arranged inside the support seat 2;

[0050] A cleaning assembly 3, which is installed inside the support seat 2;

[0051] Among them, the transmission assembly 5 includes an output rod 51 assembled inside the support seat 2. Both ends of the output rod 51 are movably sleeved with connecting rods 52. Both ends of the connecting rods 52 are fixedly installed with arc-shaped plates 56. Both ends of the arc-shaped plates 56 are fixedly installed with arc-shaped guide rods 55. A transmission convex block 57 is fixedly installed on the top of the inner wall of the support seat 2;

[0052] Both ends of the connecting rod 52 are sleeved with second elastic members 54, and the second elastic members 54 are connected between the arc-shaped plates 56 and the output rod 51;

[0053] The support assembly 4 includes a cross plate 41 sliding on the support seat 2, and the bottom of the cross plate 41 contacts the meat products conveyed by the conveying equipment 6;

[0054] The top of one end of the horizontal plate 41 is rounded, and the bottom of the arc-shaped plate 56 is adapted to one end of the horizontal plate 41;

[0055] When the arc-shaped plate 56 rotates to the bottom of the support seat 2 and the arc-shaped plate 56 is in contact with the horizontal plate 41, the bottom of the arc-shaped plate 56 is higher than the bottom of the horizontal plate 41;

[0056] The two arc-shaped plates 56 are connected by a stabilizing rod 53, and the stabilizing rod 53 passes through the middle of the output rod 51;

[0057] The output rod 51 drives the arc-shaped plate 56 and the arc-shaped guide rod 55 to rotate. The upper arc-shaped guide rod 55 is guided by the transmission convex block 57, and the lower arc-shaped plate 56 is pushed down to contact the horizontal plate 41 through the connecting rod 52.

[0058] Place the meat product on the conveying device 6 for conveying. The meat product passes through the bottom of the support seat 2 in sequence, and the bottom of the horizontal plate 41 is in contact with the meat product. The hair on the surface of the meat product will contact one end of the horizontal plate 41 during the conveying process. Drive the output rod 51, the arc-shaped plate 56 and the arc-shaped guide rod 55 to rotate through the driving motor. The upper arc-shaped guide rod 55 is guided by the transmission convex block 57 and pushes the lower arc-shaped plate 56 to move down through the connecting rod 52 and the stabilizing rod 53, so that the arc-shaped plate 56 is in contact with the horizontal plate 41, and the hair on the surface of the meat product is clamped between the arc-shaped plate 56 and the horizontal plate 41. Then, the arc-shaped plate 56 is used to push the horizontal plate 41 to move synchronously, so as to realize the extraction of the hair on the surface of the meat product, effectively avoid the exposure of the remaining hair roots in the subsequent processing, reduce the food safety risk, and improve the production quality of the meat product.

[0059] At the same time, needles or baffles for improving the stable conveying of the meat product can be arranged outside the conveying device 6 to ensure that the meat product can enter the bottom of the support seat 2.

[0060] Such as Figures 4 - 6 As shown, the support assembly 4 includes guide grooves opened on both sides of the support seat 2 for the horizontal plate 41 to slide. Limit frames 44 are fixedly installed on both sides of the support seat 2. Guide rods 43 are fixedly installed inside the limit frames 44. The horizontal plate 41 slides on the guide rods 43 through the docking parts 42. A reset elastic member 45 for propping up the docking parts 42 is arranged inside the limit frames 44;

[0061] The guide grooves are inclined from the end close to the arc-shaped plate 56. The arc-shaped plate 56 pushes the horizontal plate 41 to move along the guide grooves, so that the horizontal plate 41 gradually disengages from the contact with the arc-shaped plate 56.

[0062] Place the meat product on the conveying device 6 and convey it past the bottom of the support seat 2. The bottom of the cross plate 41 contacts the skin of the meat product. The hair on the skin will contact one end of the cross plate 41, and the arc plate 56 rotates to the bottom and contacts one end of the cross plate 41, then the hair can be clamped between the arc plate 56 and the cross plate 41. By pushing the cross plate 41 to move synchronously with the arc plate 56, the hair on the skin of the meat product can be removed. The cross plate 41 moves along the guiding groove and compresses the reset elastic member 45 through the docking member 42. As the cross plate 41 continues to move along the guiding groove, it gradually disengages from the contact with the arc plate 56, and the cross plate 41 resets under the action of the reset elastic member 45. Repeating this process in sequence can achieve the removal of the hair on the meat product.

[0063] As Figure 2 , Figure 4 , Figure 7 and Figure 8 shown, the cleaning component 3 includes a first shunt pipe 31 fixedly installed inside the support seat 2. One end of the first shunt pipe 31 is connected to the water injection device, and the other end of the first shunt pipe 31 is movably sleeved with a first valve sleeve 36;

[0064] A water passing hole 35 is opened on the first valve sleeve 36. A first cleaning pipe 34 is connected to the outside of the first shunt pipe 31. Both ends of the first cleaning pipe 34 are connected to the outside of the first shunt pipe 31, and the middle part of the first cleaning pipe 34 is arranged inside the support seat 2 and away from one end of the cross plate 41;

[0065] A water spraying hole is opened in the middle of the first cleaning pipe 34;

[0066] One end of the first valve sleeve 36 is fixedly installed with a first piston rod 32. The first piston rod 32 passes through the first shunt pipe 31, and one end of the first piston rod 32 is fixedly installed with a contact block 33;

[0067] In the initial state, the inside of the first shunt pipe 31 is communicated with the first cleaning pipe 34 through the water passing hole 35. The arc plate 56 contacts the cross plate 41, and the arc plate 56 pushes the contact block 33, the first piston rod 32 and the first valve sleeve 36 so that the water passing hole 35 does not coincide with the first cleaning pipe 34.

[0068] Inject water into the first shunt pipe 31 through the water injection device. The water in the first shunt pipe 31 enters the first cleaning pipe 34 through the water passing hole 35 and sprays out from the middle of the first cleaning pipe 34. The water blows the hair on the skin of the meat product, and the hair adheres to one end of the cross plate 41 under the action of the water flow. When the arc plate 56 contacts the cross plate 41, it is ensured that the hair of the meat product is located between the arc plate 56 and the cross plate 41, which can improve the effect of cleaning the hair on the meat product.

[0069] As Figure 2 and Figure 7As shown, the bottom of the first shunt pipe 31 is connected to a second shunt pipe 311, and one end of the second shunt pipe 311 is connected to the cross plate 41 through a second piston rod 314;

[0070] A valve plug 312 is sleeved inside the second shunt pipe 311, and an elastic cover 313 that propping up the valve plug 312 is arranged at one end inside the second shunt pipe 311;

[0071] In the initial state, the second cleaning pipe 315 is blocked by the valve plug 312.

[0072] By rotating the arc-shaped plate 56 to the lower end to contact the cross plate 41, the first shunt pipe 31 is disconnected from the first cleaning pipe 34, and the water pressure in the first shunt pipe 31 and the second shunt pipe 311 gradually increases, thereby improving the stability of the cross plate 41. By increasing the water pressure, the pressure between the cross plate 41 and the arc-shaped plate 56 is increased to ensure the effect of removing hairs from meat products;

[0073] During the process of the arc-shaped plate 56 pushing the cross plate 41 to move, the water pressure in the second shunt pipe 311 pushes the valve plug 312 to compress the elastic cover 313, so that the second cleaning pipe 315 is communicated with the second shunt pipe 311, and water is sprayed through the second cleaning pipe 315 to clean the hairs removed between the cross plate 41 and the arc-shaped plate 56, and the cleaned hairs are further cleaned by spraying water through the first cleaning pipe 34.

[0074] The present invention also provides a pretreatment method for meat product production, including the following steps:

[0075] S1. Place the meat product on the conveying device 6 for conveying. The meat product passes through the bottom of the support seat 2 in sequence, and the bottom of the cross plate 41 contacts the meat product. During the conveying of the meat product, the hairs on the epidermis will contact one end of the cross plate 41;

[0076] S2. The driving motor drives the output rod 51, the arc-shaped plate 56 and the arc-shaped guide rod 55 to rotate. The upper arc-shaped guide rod 55 is guided by the transmission convex block 57 and pushes the lower arc-shaped plate 56 to move down through the connecting rod 52 and the stabilizing rod 53, so that the arc-shaped plate 56 fits with the cross plate 41, and the hairs on the epidermis of the meat product are clamped between the arc-shaped plate 56 and the cross plate 41;

[0077] S3. The arc-shaped plate 56 pushes the cross plate 41 to move synchronously, thereby realizing the removal of the hairs on the epidermis of the meat product.

[0078] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
