Description

Technical Field

[0001] This invention relates to the field of pork kidney production equipment technology, specifically to an automated production line for pork kidneys. Background Technology

[0002] Kidney, a nutritious and delicious ingredient, is widely used in the catering and food processing industries. With expanding market demand, the production and processing scale of kidney has gradually increased. Current kidney production mainly involves thawing, soaking, and cleaning processes, often employing a combination of manual operation and decentralized equipment. The production process lacks systematic integration, and the connection between each step relies on manual transfer, resulting in low production efficiency, high labor intensity, and high labor costs.

[0003] In the thawing process, existing thawing equipment mostly adopts a whole water bath or hot air direct blowing structure, lacking zoned temperature control and flexible conveying design, resulting in uneven thawing of pork kidneys, with the center not thawed and the surface over-thawed. Furthermore, the hard conveying parts are prone to damaging the pork kidney tissue, resulting in a high rate of blood residue. In the cleaning process, cleaning equipment mostly adopts a high-pressure spray or brush rolling structure. High-pressure spray can easily cause pork kidneys to splatter and the meat to become mushy, while brush rolling has cleaning dead corners, such as inside the cut seams of the pork kidneys. Moreover, after the brushes wear down, they are prone to leaving behind fibrous impurities, affecting the hygiene of the food. Summary of the Invention

[0004] The purpose of this invention is to provide an automated production line for pork waist puffs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated production line for pork waist puffs, including a material rack and a control console located on one side of the material rack. The material rack is equipped with a feeding conveyor component, a separating conveyor component is located below the end of the feeding conveyor component, a defrosting component is located on the separating conveyor component, a soaking tank is located below the end of the separating conveyor component, a circulating disinfection component is installed on the outer casing of the soaking tank, and a cleaning component is located on one side of the soaking tank. The material rack includes symmetrically arranged side plates, one end of which is welded with an arc-shaped material feed plate, which is located directly above the separating conveying assembly; The defrosting assembly includes an insulation cover, a fixed side frame, a steam spray plate, a branch solenoid valve, a branch pipeline, a steam adding main pipe, and a temperature sensor. A support rod is welded to the fixed side frame, and the support rod is fixed to one side of the insulation cover by screws. The steam spray plate is installed at one end of the branch pipeline, and the branch solenoid valve is installed on the branch pipeline. Furthermore, the branch pipes are fixed to the top of the insulation cover, the temperature sensor is installed on one side of the branch pipe and extends into it, and the branch pipes are all connected to the steam addition main pipe.

[0006] Based on feedback data from the temperature sensor, the control console opens the branch solenoid valves in the corresponding areas. Low-pressure steam supplied by the main steam supply pipe is distributed to the steam spray plates through branch pipes, spraying steam evenly onto the pork kidneys. The control console controls the temperature of each thawing zone by controlling the opening of the branch solenoid valves. The first temperature control zone achieves initial thawing of the pork kidney surface, the second temperature control zone promotes the melting of the internal ice layer, and the third temperature control zone completes the thawing. The zoned temperature control design, through the linkage between the temperature sensor and the branch solenoid valves, avoids the problem of "unthawed center and over-melted surface" in traditional overall thawing. The uniform spray structure of the steam spray plates maximizes the heating area of ​​the pork kidneys, greatly improving thawing efficiency. At the same time, the gentle thawing method of low-pressure steam reduces tissue damage to the pork kidneys and minimizes the residual blood.

[0007] The cleaning assembly includes a cleaning hood, a fan-shaped spray nozzle, a flow regulating valve, a water pump, a cleaning fluid collection box, a brush roller, a motor, and a cleaning box transport component. The fan-shaped spray nozzle is fitted into the side wall of the fixed cleaning hood on both sides. The fan-shaped spray nozzle is connected to the flow regulating valve through a conduit, and the flow regulating valve is connected to the water pump through a conduit.

[0008] Furthermore, one end of the water pump is connected to the inside of the cleaning fluid collection box via a pipe. The cleaning fluid collection box is located directly below the cleaning hood. The cleaning box transport component includes rubber guide rollers, which are equidistantly installed between guide frames and rotate in cooperation. One end of each rubber guide roller is welded with a pulley, and a belt is sleeved between adjacent pulleys. One end of the rubber guide roller at the tail is connected to a servo motor. Two sets of fan-shaped spray nozzles are provided, and the nozzles are symmetrically arranged facing the rubber guide rollers.

[0009] Furthermore, one end of the brush roller passes through the support frame and is connected to the motor. Both the support frame and the motor are fixed to the guide frame with screws. The brush roller is made of nylon and has spiral bristles on its surface. The brush roller and the rubber guide roller are arranged at a 30-degree angle. A laser sensor is fixed to the starting end of the guide frame with screws. The laser sensor emitter faces the rubber guide roller and is slightly higher than the rubber guide roller. The laser sensor is electrically connected to the control console.

[0010] The control console activates the servo motor, motor, and water pump. The servo motor drives the rubber guide rollers to rotate synchronously via pulleys and belts. Under the conveying channel formed by the rubber guide rollers, the material box carrying the pork kidneys enters the cleaning hood. The water pump extracts the cleaning liquid from the cleaning liquid collection box and delivers it to the fan-shaped spray nozzles, spraying liquid streams onto the surface of the pork kidneys for cleaning. At the same time, the motor drives the brush rollers to rotate, and the spiral bristles penetrate deep into the cuts of the pork kidneys to clean them. The waste liquid after cleaning flows back to the cleaning liquid collection box for recycling. The symmetrical arrangement of the fan-shaped spray nozzles achieves all-round coverage cleaning of the pork kidneys. The control console adjusts the spray pressure of the fan-shaped spray nozzles through the flow regulating valve to ensure cleaning power while avoiding meat rotting. The brush rollers and rubber guide rollers are at a 30-degree angle. When the spiral bristles rotate, they generate centripetal friction, which removes impurities in the cuts without sweeping the pork kidneys off, greatly improving cleaning efficiency.

[0011] Furthermore, the separating conveyor assembly includes a silicone conveyor belt with symmetrically arranged flexible curved baffles on its surface. Several isolation plates are equidistantly arranged between the flexible curved baffles. Several heat insulation covers are provided and equidistantly fitted above the silicone conveyor belt. The silicone conveyor belt is fixed to a chain by screws. The chain is symmetrically arranged and has several gears embedded on its inner side. The gears are welded to a rotating shaft. Bearings are fitted at both ends of the rotating shaft and rotate in cooperation. One end of one of the rotating shafts is connected to a power motor.

[0012] The kidney slices are separated into independent processing units by partitions. Flexible bending baffles limit the left and right deviation of the kidney slices. The silicone conveyor belt is made of food-grade flexible material. Together with the physical separation of the partitions, it prevents the kidney slices from being squeezed and damaged during the conveying process. The elastic design of the flexible bending baffles prevents the kidney slices from falling off without damaging the meat, laying the foundation for uniform processing in subsequent processes. The power motor drives the shaft to rotate in the bearing, which in turn drives the gear to rotate. The gear drives the silicone conveyor belt on the chain to rotate, and the kidney slices enter the area covered by the heat preservation cover along with the silicone conveyor belt.

[0013] Furthermore, the feeding and conveying assembly includes several conveying rollers, with material racks fitted at both ends of the conveying rollers and rotating in cooperation. A conveyor belt is nested on the outside of the conveying rollers, and one end of one of the conveying rollers is connected to a speed reducer. The speed reducer is connected to a rotating motor, and the arc-shaped unloading plate is located at the end of the conveyor belt in the direction of rotation.

[0014] The operator evenly spreads the frozen pork kidneys on the conveyor belt of the feeding and conveying component. The operator starts the rotating motor through the control console. After the speed is adjusted by the reducer, the conveyor roller drives the conveyor belt to transport the pork kidneys. The pork kidneys are guided by the arc-shaped unloading plate and fall precisely onto the silicone conveyor belt of the separating conveyor component.

[0015] Furthermore, the soaking tank is located at the end of the rotating direction of the silicone conveyor belt. The outer side of the soaking tank is provided with a reagent addition port, and the inner side of the soaking tank is provided with a filter. One end of the filter is fixed to the flip plate by screws. The flip plate is symmetrically welded to the flip shaft. The two ends of the flip shaft are fitted with support bearings and rotate in cooperation. One end is connected to the flip motor. An ultrasonic generator and a stirring paddle are installed at the bottom of the soaking tank. One end of the stirring paddle is connected to a stirring motor. The stirring motor is installed on the outside of the soaking tank by screws. The flip motor is electrically connected to the control console.

[0016] After thawing, the pork kidneys fall into the filter hopper of the soaking tank via the end of the silicone conveyor belt. The operator adds deodorizing agents, such as a mixture of ginger juice and cooking wine, through the agent addition port. The control panel activates the ultrasonic generator and stirring motor. The stirring paddle rotates the soaking liquid, and the ultrasonic waves generate a cavitation effect in the liquid. After ten minutes of continuous action, a material box is placed on the initial end of the rubber guide roller. The laser sensor's emission path is blocked, and the signal is transmitted back to the control panel, which then activates the tilting motor. The tilting shaft drives the tilting plate to tilt, and the filter hopper tilts, pouring the pork kidneys into the material box. When the microbubbles generated by the ultrasonic cavitation effect burst, they release instantaneous pressure, which can penetrate deep into the interstitial spaces of the pork kidneys to remove blood and odor substances. The rotation of the stirring paddle ensures that the soaking liquid and agents are evenly mixed, avoiding differences in deodorizing effect caused by uneven local concentration. The tilting discharge design of the filter hopper eliminates the need for manual transfer, reducing the risk of secondary contamination.

[0017] Furthermore, the circulating disinfection component includes a water pump, an activated carbon filter, a disinfection box, ultraviolet disinfection lamps, a water spray column, and a water pumping pipe. Two water pumps are provided and installed between the water pumping pipe and the activated carbon filter, and between the disinfection box and the water spray column, respectively. The water pumping pipe connects to the inside of the soaking box. The activated carbon filter is connected to the disinfection box through a conduit. Several ultraviolet disinfection lamps are provided and installed at equal intervals on the top of the disinfection box. The top of the water spray column extends to the top of the soaking box.

[0018] A water pump draws liquid from the bottom of the soaking tank, filters impurities through an activated carbon filter, and then sends it to a sterilization tank. An ultraviolet sterilization lamp sterilizes the liquid, which is then returned to the soaking tank via a water spray column. The activated carbon filter adsorbs impurities and odors in the soaking solution, while the ultraviolet sterilization lamp kills harmful microorganisms, increasing the number of times the soaking solution can be reused and reducing production costs. The circulating soaking solution avoids localized contamination caused by static soaking, ensuring the hygiene and safety of food.

[0019] Furthermore, a bubble-enhanced stripping assembly is added to the pipeline between the cleaning fluid collection box and the water pump. The bubble-enhanced stripping assembly includes a gas-liquid mixing proportioning valve, a Venturi mixer, an air intake, and an exhaust valve. The Venturi mixer includes a contraction section, a throat, and a diffusion section. The contraction section is connected to the gas-liquid mixing proportioning valve, and the gas-liquid mixing proportioning valve is connected to the cleaning fluid collection box through a pipeline.

[0020] Furthermore, the air intake is connected to the connection between the diffuser section and the throat, and the diffuser section is connected to the water pump through a pipe, with the exhaust valve installed on this pipe.

[0021] For the kidney-shaped product with many surface impurities, the cleaning fluid is drawn from the cleaning fluid collection box, regulated by the gas-liquid mixing proportioning valve, and then enters the contraction section of the Venturi mixer. The cross-section of the pipe in the contraction section gradually decreases in diameter. As the flow area decreases during the flow of the cleaning fluid, the flow velocity increases sharply along the flow path. According to Bernoulli's equation, when the fluid velocity increases, the static pressure will decrease simultaneously. When the cleaning fluid flows at high speed through the end of the contraction section, a significant negative pressure is formed in the throat area. This negative pressure is connected to the outside atmosphere through the air inlet, generating a strong suction force that draws outside air into the Venturi mixer. The air initially contacts the high-speed flowing cleaning fluid and is broken into tiny bubbles. The gas-liquid mixture flows from the throat into the diffusion section, where the pipe cross-section gradually expands, the flow velocity decreases along the flow path, and the static pressure gradually rises. During the pressure rise, the liquid pressure on the bubbles increases, the bubble volume shrinks slightly, but the stability is improved, preventing premature rupture during subsequent transportation. During the pressure recovery process in the diffusion section of the gas-liquid mixture, some incompletely refined free large air bubbles will naturally rise to the top of the pipeline. The vent valve is installed at the top of the pipeline between the diffusion section and the pump. When the large air bubbles accumulate and cause the pressure in the pipeline to drop, the vent valve will automatically open to discharge the large air bubbles. If large air bubbles enter the pump, it will cause the pump body to run dry, the impeller to wear, and even cavitation, affecting the pump's life and the stability of the spray pressure. The vent valve can effectively avoid this risk. A stable gas-liquid mixture enters the pump, which pressurizes it and delivers it through pipes to fan-shaped spray nozzles. This spray is evenly applied to the surface of the kidney slices and the crevices, completing the cleaning process. When bubbles impact the kidney slices, especially the crevices, they rapidly burst under pressure, generating instantaneous micro-jet flow rates that can reach localized negative pressure. This powerfully removes stubborn impurities such as blood residue and fascia fragments adhering to the kidney slices, filling the dead zones that traditional brush cleaning cannot reach. Simultaneously, the bubbles form an air cushion in the cleaning solution, reducing the direct impact of the spray water on the kidney slices. Compared to high-pressure spraying with pure water, the impact intensity of the gas-liquid mixture is reduced, preventing the kidney slices from becoming mushy. Furthermore, the tiny bubbles form a dense foam on the kidney slices, extending the contact time between the cleaning solution and impurities, allowing cleaning agents such as deodorizers to fully exert their effects. The foam also carries away the removed impurities with the water flow, reducing secondary adhesion.

[0022] Compared with the prior art, the present invention provides an automated production line for pork kidneys, which has the following advantages: 1. This automated pork kidney production line integrates the thawing, soaking, and cleaning processes. It uses flexible conveyor structures such as silicone conveyor belts and rubber guide rollers to achieve seamless connection between each process. No manual handling of pork kidneys is required throughout the entire process, which greatly improves production efficiency. The control console, temperature sensor, laser sensor and other components work together to achieve precise control of parameters such as temperature, spray pressure and conveying speed, reducing the intensity of manual operation and avoiding secondary contamination of food caused by human contact, thus ensuring the hygiene and safety of the production process.

[0023] 2. This automated production line for pork kidneys solves the problems of uneven thawing and high blood residue in traditional thawing processes by using zoned temperature control and low-pressure steam spray design in the thawing process. This significantly improves the qualified rate of pork kidney thawing and reduces the tissue damage rate. In the cleaning process, a fan-shaped spray + spiral brush composite structure, combined with an optional bubble-enhanced peeling component, uses the micro-explosion effect of bubbles to fill cleaning dead corners, greatly improving the cleanliness of the pork kidneys and reducing the residual rate of impurities in the cuts. At the same time, the bubble buffer also reduces problems such as meat rot and brush brush removal caused by spraying. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0027] Please see Figures 1-12 The automated production line for pork waist includes a material rack 1 and a control console 2 located on one side of the material rack 1. The material rack 1 is equipped with a feeding conveyor component 3. A separating conveyor component 4 is located below the end of the feeding conveyor component 3. A defrosting component 5 is located on the separating conveyor component 4. A soaking tank 6 is located below the end of the separating conveyor component 4. A circulating disinfection component 7 is installed on the outer casing of the soaking tank 6. A cleaning component 8 is located on one side of the soaking tank 6. The material rack 1 includes symmetrically arranged side plates 11, and an arc-shaped feeding plate 12 is welded to one end of the side plate 11. The arc-shaped feeding plate 12 is located directly above the separating conveying assembly 4. The defrosting assembly 5 includes an insulation cover 51, a fixed side frame 52, a steam spray plate 53, a branch solenoid valve 54, a branch pipeline 55, a steam adding main pipe 56, and a temperature sensor 57. A support rod 521 is welded on the fixed side frame 52. The support rod 521 is fixed to one side of the insulation cover 51 by screws. The steam spray plate 53 is installed at one end of the branch pipeline 55, and the branch solenoid valve 54 is installed on the branch pipeline 55. Furthermore, branch pipes 55 are fixed to the top of insulation cover 51, and temperature sensors 57 are installed on one side of branch pipes 55 and extend into them. All branch pipes 55 are connected to the steam addition main pipe 56.

[0028] Based on the feedback data from the temperature sensor 57, the control console 2 controls the opening of the branch solenoid valve 54 in the corresponding area. The low-pressure steam delivered by the steam addition main pipe 56 is distributed to the steam spray plate 53 through the branch pipe 55, spraying uniform steam onto the pork kidneys. The control console 2 controls the temperature of each thawing zone by controlling the opening of the branch solenoid valve 54. The first temperature control zone achieves initial thawing of the surface of the pork kidneys, the second temperature control zone promotes the melting of the internal ice layer, and the third temperature control zone completes the thawing. The zoned temperature control design, through the linkage between the temperature sensor 57 and the branch solenoid valve 54, avoids the problem of "unthawed center and over-melted surface" in traditional overall thawing. The uniform spray structure of the steam spray plate 53 maximizes the heating area of ​​the pork kidneys, greatly improving the thawing efficiency. At the same time, the flexible thawing method of low-pressure steam reduces tissue damage to the pork kidneys and minimizes the blood residue rate.

[0029] The cleaning assembly 8 includes a cleaning hood 81, a fan-shaped spray nozzle 82, a flow regulating valve 83, a water pump 84, a cleaning fluid collection box 85, a brush roller 86, a motor 87, and a cleaning box transport component. The fan-shaped spray nozzle 82 is fitted into the side wall of the fixed cleaning hood 81 on both sides. The fan-shaped spray nozzle 82 is connected to the flow regulating valve 83 through a conduit. The flow regulating valve 83 is connected to the water pump 84 through a conduit.

[0030] Furthermore, one end of the water pump 84 is connected to the inside of the cleaning fluid collection box 85 through a pipe. The cleaning fluid collection box 85 is located directly below the cleaning hood 81. The cleaning box transport component includes rubber guide rollers 88, which are equidistantly installed between the guide frames 89 and rotate in coordination. One end of the rubber guide rollers 88 is welded with a pulley 881, and a belt 882 is sleeved between adjacent pulleys 881. One end of the rubber guide roller 88 at the tail end is connected to a servo motor 883. Two sets of fan-shaped spray nozzles 82 are provided and are symmetrically arranged facing the rubber guide rollers 88.

[0031] Furthermore, one end of the brush roller 86 passes through the support frame 861 and is connected to the motor 87. Both the support frame 861 and the motor 87 are fixed to the guide frame 89 with screws. The brush roller 86 is made of nylon and has spiral bristles on its surface. The brush roller 86 and the rubber guide roller 88 are arranged at a 30-degree angle. A laser sensor 891 is fixed to the starting end of the guide frame 89 with screws. The laser sensor 891 emits its head towards the rubber guide roller 88 and is slightly higher than the rubber guide roller 88. The laser sensor 891 is electrically connected to the control console 2.

[0032] Console 2 activates servo motor 883, motor 87, and water pump 84. Servo motor 883 drives rubber guide roller 88 to rotate synchronously via pulley 881 and belt 882. Under the conveying channel formed by the rubber guide rollers 88, the material box carrying the waist flower enters the cleaning hood 81. Water pump 84 draws cleaning liquid from the cleaning liquid collection box 85 and delivers it to the fan-shaped spray nozzle 82 to spray liquid onto the surface of the waist flower for cleaning. At the same time, motor 87 drives brush roller 86 to rotate, and the spiral bristles penetrate deep into the waist flower. The cleaning process involves cleaning the flower-cut seams, with the waste liquid returned to the cleaning liquid collection box 85 for recycling. The symmetrical arrangement of the fan-shaped spray nozzles 82 ensures all-round coverage cleaning of the flower-shaped cuts. The control panel 2 adjusts the spray pressure of the fan-shaped spray nozzles 82 through the flow regulating valve 83, ensuring cleaning power while preventing meat rot. The brush roller 86 and the rubber guide roller 88 are at a 30-degree angle, and the spiral bristles generate centripetal friction when rotating, which removes impurities from the seams without sweeping the flower-shaped cuts off, greatly improving cleaning ability.

[0033] Furthermore, the separating conveyor assembly 4 includes a silicone conveyor belt 41, on the surface of which flexible bending baffles 42 are symmetrically arranged, and several isolation plates 43 are equidistantly arranged between the flexible bending baffles 42. A heat insulation cover 51 is provided with several equidistantly fitted above the silicone conveyor belt 41. The silicone conveyor belt 41 is fixed to a chain 44 by screws. The chain 44 is symmetrically arranged and has several gears 45 embedded on its inner side. The gears 45 are welded to a rotating shaft 46. The two ends of the rotating shaft 46 are fitted with bearings 47 and rotate in cooperation. One end of one of the rotating shafts 46 is connected to a power motor 48.

[0034] The kidney slices are divided into independent processing units by the partition plate 43. The flexible bending baffle 42 restricts the kidney slices from shifting left and right. The silicone conveyor belt 41 is made of food-grade flexible material. Together with the physical separation of the partition plate 43, it prevents the kidney slices from being squeezed and damaged during the conveying process. The elastic design of the flexible bending baffle 42 prevents the kidney slices from falling off without damaging the meat quality, laying the foundation for uniform processing in subsequent processes. The power motor 48 drives the rotating shaft 46 to rotate in the bearing 47, which in turn drives the gear 45 to rotate. The gear 45 drives the silicone conveyor belt 41 on the chain 44 to rotate. The kidney slices enter the area covered by the heat preservation cover 51 along with the silicone conveyor belt 41.

[0035] Furthermore, the feeding and conveying assembly 3 includes several conveying rollers 31, with the material rack 1 fitted into both ends of the conveying rollers 31 and rotating in cooperation. A conveyor belt 32 is nested on the outside of the conveying rollers 31. One end of one of the conveying rollers 31 is connected to a reducer 33, and the reducer 33 is connected to a rotating motor 34. An arc-shaped unloading plate 12 is located at the end of the conveyor belt 32 in the direction of rotation.

[0036] The operator evenly spreads the frozen pork kidneys on the conveyor belt 32 of the feeding and conveying component 3. The operator starts the rotating motor 34 through the control console 2. After the speed is adjusted by the reducer 33, the conveyor roller 31 drives the conveyor belt 32 to transport the pork kidneys. The pork kidneys are guided by the arc-shaped unloading plate 12 and fall precisely onto the silicone conveyor belt 41 of the separating conveying component 4.

[0037] Furthermore, the soaking tank 6 is located at the end of the rotating direction of the silicone conveyor belt 41. The outer side of the soaking tank 6 is provided with a reagent addition port 61, and the inner side of the soaking tank 6 is provided with a filter 62. One end of the filter 62 is fixed to the tilting plate 63 by screws. The tilting plate 63 is symmetrically welded to the tilting shaft 64. The two ends of the tilting shaft 64 are fitted with support bearings 65 and rotate in cooperation. One end is connected to the tilting motor 66. An ultrasonic generator 67 and a stirring paddle 68 are installed at the bottom of the soaking tank 6. One end of the stirring paddle 68 is connected to the stirring motor 69. The stirring motor 69 is installed on the outside of the soaking tank 6 by screws. The tilting motor 66 is electrically connected to the control console 2.

[0038] After thawing, the pork kidneys fall into the filter 62 of the soaking tank 6 via the end of the silicone conveyor belt 41. The operator adds deodorizing agents, such as a mixture of ginger juice and cooking wine, through the agent addition port 61. The control console 2 starts the ultrasonic generator 67 and the stirring motor 69. The stirring paddle 68 drives the soaking liquid to rotate. The ultrasonic waves generate a cavitation effect in the liquid. After ten minutes of continuous action, the material box is placed on the initial end of the rubber guide roller 88. The laser sensor 891 transmits a signal back to the control console 2 after its emission path is blocked, which then starts the flipping motor 66. The flipping shaft 64 drives the flipping plate 63 to flip, and the filter 62 tilts to pour the pork kidneys into the material box. When the microbubbles generated by the ultrasonic cavitation effect burst, they release instantaneous pressure, which can penetrate into the interstitial spaces of the pork kidneys to remove blood and odor substances. The rotation of the stirring paddle 68 makes the soaking liquid and agents evenly mixed, avoiding differences in deodorizing effect caused by uneven local concentration. The flipping discharge design of the filter 62 eliminates the need for manual transfer and reduces the risk of secondary contamination.

[0039] Furthermore, the circulating disinfection component 7 includes a water pump 71, an activated carbon filter element 72, a disinfection box 73, an ultraviolet disinfection lamp 74, a water spray column 75, and a water pumping pipe 76. Two water pumps 71 are provided and are respectively installed between the water pumping pipe 76 and the activated carbon filter element 72, and between the disinfection box 73 and the water spray column 75. The water pumping pipe 76 connects to the inside of the soaking box 6. The activated carbon filter element 72 is connected to the disinfection box 73 through a conduit. Several ultraviolet disinfection lamps 74 are provided and are installed at equal intervals on the top of the disinfection box 73. The top of the water spray column 75 extends to the top of the soaking box 6.

[0040] Water pump 71 draws liquid from the bottom of soaking tank 6, filters impurities through activated carbon filter 72, and then sends it to sterilization tank 73. Ultraviolet sterilization lamp 74 sterilizes the liquid, which is then returned to soaking tank 6 through water spray column 75.

[0041] Please see Figure 11 as well as Figure 13 The difference between Embodiment 2 and Embodiment 1 is that a bubble-enhanced stripping assembly 9 is added to the pipeline between the cleaning fluid collection box 85 and the pump 84. The bubble-enhanced stripping assembly 9 includes a gas-liquid mixing proportioning valve 91, a venturi mixer 92, an air intake 93, and an exhaust valve 94. The venturi mixer 92 includes a contraction section 921, a throat 922, and a diffusion section 923. The contraction section 921 is connected to the gas-liquid mixing proportioning valve 91, and the gas-liquid mixing proportioning valve 91 is connected to the cleaning fluid collection box 85 through a pipeline.

[0042] Furthermore, the air intake 93 connects to the connection between the diffuser section 923 and the throat 922. The diffuser section 923 is connected to the pump 84 via a pipe, and the exhaust valve 94 is installed on this pipe.

[0043] For the kidney-shaped flower with many surface impurities, the cleaning fluid is drawn from the cleaning fluid collection box 85 and regulated by the gas-liquid mixing proportion valve 91 before entering the contraction section 921 of the Venturi mixer 92. The cross-section of the pipe in the contraction section 921 gradually decreases in diameter. As the flow area of ​​the cleaning fluid decreases during the flow process, the flow velocity increases sharply along the path. According to Bernoulli's equation, when the fluid velocity increases, the static pressure will decrease simultaneously. When the cleaning fluid flows at high speed through the end of the contraction section 921, a significant negative pressure is formed in the throat 922 region. This negative pressure is connected to the outside atmosphere through the air intake 93, generating a strong suction force that draws outside air into the Venturi mixer. The air comes into initial contact with the high-speed flowing cleaning fluid and is broken into tiny bubbles. The gas-liquid mixture flows from the throat 922 into the diffusion section 923, where the pipe cross-section gradually expands, the flow velocity decreases along the path, and the static pressure gradually rises. During the pressure rise, the liquid pressure on the bubbles increases, the bubble volume shrinks slightly but the stability is improved, preventing premature rupture during subsequent transportation. During the pressure recovery process in the diffuser section 923 of the gas-liquid mixture flow, some incompletely refined free large air bubbles will naturally rise to the top of the pipeline. The exhaust valve 94 is installed at the top of the pipeline between the diffuser section 923 and the pump 84. When the large air bubbles accumulate and cause the pressure in the pipeline to drop, the exhaust valve 94 will automatically open to discharge the large air bubbles. If large air bubbles enter the pump 84, it will cause the pump body to run dry, the impeller to wear, and even cavitation, affecting the life of the pump and the stability of the spray pressure. The exhaust valve 94 can effectively avoid this risk. A stable gas-liquid mixture enters the pump 84, which pressurizes it and delivers it through pipes to the fan-shaped spray nozzle 82. The mixture is evenly sprayed onto the surface of the kidney slices and into the cuts, completing the cleaning process. When the bubbles impact the surface of the kidney slices, especially into the cuts, they rapidly burst under pressure, generating instantaneous micro-jet flow rates that can reach localized negative pressure. This powerfully removes stubborn impurities such as blood residue and fascia fragments adhering to the surface of the kidney slices, filling the dead zones that traditional brush cleaning cannot reach. Simultaneously, the bubbles form an air cushion in the cleaning liquid, reducing the direct impact of the sprayed water on the kidney slice meat. Compared to high-pressure spraying with pure water, the impact intensity of the gas-liquid mixture spraying is reduced, preventing the kidney slice meat from becoming mushy. Furthermore, the tiny bubbles form a dense foam on the surface of the kidney slices, prolonging the contact time between the cleaning liquid and impurities, allowing cleaning agents such as deodorizers to fully exert their effects. At the same time, the foam can carry away the removed impurities with the water flow, reducing secondary adhesion.

[0044] The specific usage and function of this embodiment are as follows: In use, the temperature of the temperature control zone corresponding to the heat preservation cover 5, the spray pressure of the fan-shaped spray nozzle 82, and the running speed of the rubber guide roller 88 are set synchronously with the silicone conveyor belt 41 via the control console 2. Then, the operator evenly spreads the frozen pork kidneys on the conveyor belt 32 of the feeding conveyor assembly 3. The rotating motor 34 is started via the control console 2. After the speed is adjusted by the reducer 33, the conveyor roller 31 drives the conveyor belt 32 to transport the pork kidneys. The pork kidneys are guided by the arc-shaped unloading plate 12 and fall precisely onto the silicone conveyor belt 41 of the separating conveyor assembly 4. They are separated into independent processing units by the partition plate 43. The flexible bending baffle 42 restricts the left and right deviation of the pork kidneys. The silicone conveyor belt 41 is made of food-grade flexible material. With the physical separation of the partition plate 43, the pork kidneys are prevented from being squeezed and damaged during the conveying process. The elastic design of the flexible bending baffle 42 prevents the pork kidneys from falling and does not damage the meat, laying the foundation for uniform processing in subsequent processes.

[0045] Subsequently, under the control of console 2, motor 48 drives shaft 46 to rotate in bearing 47, which in turn drives gear 45 to rotate. Gear 45 drives silicone conveyor belt 41 on chain 44 to rotate. The waist flower enters the area covered by insulation cover 51 along with silicone conveyor belt 41. Based on the feedback data from temperature sensor 57, console 2 controls the opening of branch solenoid valve 54 in the corresponding area. Low-pressure steam delivered by steam main pipe 56 is distributed to steam spray plate 53 through branch pipe 55, spraying steam evenly onto the waist flower. Console 2 controls the branch... The opening of the solenoid valve 54 controls the temperature of each thawing zone. The first temperature control zone achieves initial thawing of the surface of the pork kidney, the second temperature control zone promotes the melting of the internal ice layer, and the third temperature control zone completes the thawing. The zoned temperature control design avoids the problem of "unthawed center and over-melted surface" in traditional whole thawing through the linkage of temperature sensor 57 and branch solenoid valve 54. The uniform spray structure of the steam spray plate 53 maximizes the heating area of ​​the pork kidney and greatly improves the thawing efficiency. At the same time, the soft thawing method of low-pressure steam reduces the damage to the pork kidney tissue and reduces the blood residue rate.

[0046] After thawing, the pork kidneys fall into the filter 62 of the soaking tank 6 via the end of the silicone conveyor belt 41. The operator adds deodorizing agents, such as a mixture of ginger juice and cooking wine, through the agent addition port 61. The control console 2 starts the ultrasonic generator 67 and the stirring motor 69. The stirring paddle 68 drives the soaking liquid to rotate. The ultrasonic waves generate a cavitation effect in the liquid. After ten minutes of continuous action, the material box is placed on the initial end of the rubber guide roller 88. The laser sensor 891 transmits a signal back to the control console 2 after its emission path is blocked, which then starts the flipping motor 66. The flipping shaft 64 drives the flipping plate 63 to flip, and the filter 62 tilts to pour the pork kidneys into the material box. When the microbubbles generated by the ultrasonic cavitation effect burst, they release instantaneous pressure, which can penetrate into the interstitial spaces of the pork kidneys to remove blood and odor substances. The rotation of the stirring paddle 68 makes the soaking liquid and agents evenly mixed, avoiding differences in deodorizing effect caused by uneven local concentration. The flipping discharge design of the filter 62 eliminates the need for manual transfer and reduces the risk of secondary contamination.

[0047] During the soaking process, the circulating disinfection component 7 operates continuously. The water pump 71 draws liquid from the bottom of the soaking tank 6, filters impurities through the activated carbon filter 72, and then sends it into the disinfection tank 73. The ultraviolet disinfection lamp 74 sterilizes the liquid, and then it flows back to the soaking tank 6 through the water spray column 75. After cleaning, the pork kidneys are conveyed to the discharge end by the rubber guide roller 88, where operators carry out subsequent packaging or processing. The activated carbon filter 72 adsorbs impurities and odors in the soaking solution, and the ultraviolet disinfection lamp 74 kills harmful microorganisms, increasing the number of times the soaking solution can be recycled by 60% and reducing production costs. The circulating soaking solution avoids local contamination caused by static soaking, ensuring the hygiene and safety of the food.

[0048] Subsequently, console 2 activates servo motor 883, motor 87, and water pump 84. Servo motor 883 drives rubber guide roller 88 to rotate synchronously via pulley 881 and belt 882. Under the conveying channel formed by the rubber guide roller 88, the material box carrying the waist flower enters the cleaning hood 81. Water pump 84 draws cleaning liquid from the cleaning liquid collection box 85 and delivers it to the fan-shaped spray nozzle 82 to spray liquid onto the surface of the waist flower for cleaning. At the same time, motor 87 drives brush roller 86 to rotate, and the spiral bristles penetrate deep into the brush. The slits of the pork kidneys are cleaned, and the waste liquid after cleaning is returned to the cleaning liquid collection box 85 for recycling. The symmetrical arrangement of the fan-shaped spray nozzles 82 achieves all-round coverage cleaning of the pork kidneys. The control console 2 adjusts the spray pressure of the fan-shaped spray nozzles 82 through the flow regulating valve 83 to ensure cleaning power while avoiding meat rotting. The brush roller 86 and the rubber guide roller 88 are at a 30-degree angle. When the spiral bristles rotate, they generate centripetal friction, which removes impurities in the slits without sweeping the pork kidneys off, greatly improving the cleaning ability.

[0049] For the kidney-shaped pipe with many surface impurities, an air-bubble enhanced stripping component 9 is added to the pipeline between the cleaning fluid collection box 85 and the pump 84. The cleaning fluid is drawn from the cleaning fluid collection box 85, regulated by the gas-liquid mixing proportioning valve 91, and then enters the contraction section 921 of the Venturi mixer 92. The cross-section of the pipe in the contraction section 921 gradually decreases in inlet diameter. During the flow process, the flow velocity of the cleaning fluid increases sharply along the flow path due to the reduced flow area. According to Bernoulli's equation, when the fluid velocity increases, the static pressure will decrease simultaneously. When the cleaning fluid flows at high speed through the end of the contraction section 921... A significant negative pressure is formed in the throat 922 region. This negative pressure is connected to the outside atmosphere through the air intake 93, generating a strong suction that draws outside air into the Venturi mixer. The air comes into initial contact with the high-speed flowing cleaning liquid and is broken into tiny bubbles. The gas-liquid mixture flows from the throat 922 into the diffuser section 923, where the pipe cross-section gradually expands, the flow velocity decreases along the flow path, and the static pressure gradually rises. During the pressure rise, the liquid pressure on the bubbles increases, the bubble volume shrinks slightly but the stability is improved, preventing premature rupture during subsequent transport.

[0050] During the pressure recovery process in the diffuser section 923 of the gas-liquid mixture flow, some incompletely refined free large air bubbles will naturally rise to the top of the pipeline. The exhaust valve 94 is installed at the top of the pipeline between the diffuser section 923 and the pump 84. When the large air bubbles accumulate and cause the pressure in the pipeline to drop, the exhaust valve 94 will automatically open to discharge the large air bubbles. If large air bubbles enter the pump 84, it will cause the pump body to run dry, the impeller to wear, and even cavitation, affecting the life of the pump and the stability of the spray pressure. The exhaust valve 94 can effectively avoid this risk. A stable gas-liquid mixture enters the pump 84, which pressurizes it and delivers it through pipes to the fan-shaped spray nozzle 82. The mixture is evenly sprayed onto the surface of the kidney slices and into the cuts, completing the cleaning process. When the bubbles impact the surface of the kidney slices, especially into the cuts, they rapidly burst under pressure, generating instantaneous micro-jet flow rates that can reach localized negative pressure. This powerfully removes stubborn impurities such as blood residue and fascia fragments adhering to the surface of the kidney slices, filling the dead zones that traditional brush cleaning cannot reach. Simultaneously, the bubbles form an air cushion in the cleaning liquid, reducing the direct impact of the sprayed water on the kidney slice meat. Compared to high-pressure spraying with pure water, the impact intensity of the gas-liquid mixture spraying is reduced, preventing the kidney slice meat from becoming mushy. Furthermore, the tiny bubbles form a dense foam on the surface of the kidney slices, prolonging the contact time between the cleaning liquid and impurities, allowing cleaning agents such as deodorizers to fully exert their effects. At the same time, the foam can carry away the removed impurities with the water flow, reducing secondary adhesion.
