Description

Technical Field

[0001] This invention relates to the field of meat processing technology, specifically to a tumbling and marinating device for processing seasoned meat products. Background Technology

[0002] Processed meat products refer to meat products made primarily from livestock and poultry meat, processed through trimming, cutting, marinating, tumbling, and other techniques, with the addition of seasonings, spices, and other auxiliary ingredients. These products are ready to be cooked or heated and consumed directly. They are tender, flavorful, and convenient to eat, and have become an important category in the food processing industry, widely used in catering, retail, and other fields. Tumbling and marinating is the core process in processed meat product processing. Its key function is to relax the muscle fibers through the physical impact and compression generated by mechanical tumbling, while allowing the marinade to fully penetrate the meat, ensuring even flavor and a delicate texture. It also improves the meat's water retention and yield, extending its shelf life. Therefore, the performance of the tumbling and marinating equipment directly determines the quality and production efficiency of processed meat products.

[0003] Most existing equipment pours the marinade into the tumbling drum all at once before tumbling begins. This method tends to cause the marinade to accumulate at the bottom of the drum, resulting in more contact between the meat pieces near the walls and the marinade, while the center remains poorly marinated, leading to uneven color and flavor in the final product. Furthermore, the inner walls of the tumbling drum are often smooth or have simple baffles, limiting the kneading effect on the meat and hindering the diffusion of the marinade between muscle fibers. Additionally, traditional tumbling machines often use a constant vacuum environment. While negative pressure can expand the gaps between meat fibers, prolonged constant negative pressure gradually weakens the driving force of the marinade flow, failing to create a pumping effect on the meat pieces. This results in large pieces of meat failing to reach the desired marinating depth in a short time, leading to a longer overall processing cycle. Summary of the Invention

[0005] As a preferred embodiment of the present invention, the pressure tank includes a piston plate, a rubber ring, a spring, a tank body, and a base. The base is rotatably mounted on the top of a base plate. The protruding part of the top of the base is threadedly connected to the inner side of the lower end of the tank body.

[0006] As a preferred embodiment of the present invention, the liquid removal tank includes a baffle, a tank body and a drain cover. An L-shaped baffle is fixedly connected to the inner wall of the upper end of the tank body. The baffle is located between the air inlet and the air outlet on the tank body. The lower end of the tank body is inverted conical and the bottom is threadedly connected to the drain cover.

[0007] As a preferred embodiment of the present invention, a fixing ring is fixedly installed on the side of the upper end of the base plate, the side of the fixing ring is fixedly connected to the inner side of the bearing, the side of the bearing is fixedly connected to the side of the rotating ring, and the end face of the rotating ring is fixedly connected to the end face of the tumbling drum.

[0008] As a preferred embodiment of the present invention, the driving mechanism includes a first pulley, a belt, a motor, and a second pulley. The first pulley is annular, with its inner side fixedly connected to the side of the rotating ring. The motor is fixedly mounted on the side of the base plate, and the output shaft of the motor passes through a through hole on the side of the base plate and is fixedly connected to the middle of the end face of the second pulley. The first pulley and the second pulley are connected by a belt.

[0009] As a preferred embodiment of the present invention, the side of one end of the base plate is rotatably connected to the opposite side of the upper end of the support base. The support base is L-shaped. Two fixing blocks are fixedly installed on the top of the other end of the support base and the top of the other end of the base plate. The two fixing blocks on the same side are rotatably connected to the sides of both ends of the hydraulic cylinder. The hydraulic cylinder is electrically connected to the control module.

[0010] As a preferred embodiment of the present invention, the inner wall of the tumbling drum is provided with protruding spiral patterns.

[0011] As a preferred embodiment of the present invention, four support plates are fixedly installed on the top of one end of the base plate, and support wheels are rotatably installed in the grooves at the upper end of the four support plates, with the side of the support wheels contacting the side of the tumbling drum.

[0012] As a preferred embodiment of the present invention, two arc-shaped plates are fixedly connected to the end face of the opening of the tumbling drum. The sides of the two arc-shaped plates are provided with grooves. Two clamping plates are fixedly installed on the side of the sealing cover. The two clamping plates respectively cooperate with the grooves on the two arc-shaped plates. Bolts are threaded into the threaded holes on the sides of the two clamping plates. Two connecting plates are fixedly installed on the side of one end of the tumbling drum. The sides of the two connecting plates are provided with through holes that cooperate with the two bolts.

[0013] The beneficial effects of this invention are: 1. This invention uses an infusion pump to pump liquid into the tank and compress a spring. The spring applies stable pressure to the liquid through a piston plate, causing the liquid to flow out of the tank through the infusion hole at a constant pressure. This evenly sprays the liquid onto the surface of each piece of meat in the tumbling drum, preventing the liquid from accumulating at the bottom of the drum. This significantly improves the uniformity of liquid distribution and absorption efficiency. Five tumbling protrusions are evenly distributed inside the tumbling drum and rotate synchronously with the drum. They can achieve the physical impact and squeezing effect of traditional tumbling protrusions, loosening the meat fibers and ensuring consistent flavor penetration inside and outside the meat, thus improving the taste and quality stability of the prepared meat products.

[0014] 2. During the tumbling process, the solenoid valve switches, causing the air pump and vacuum pump to alternately extract and supply air into the tumbling drum, resulting in a cyclical change in the environment within the drum between negative vacuum and positive air pressure. During the negative pressure phase, air and excess liquid between meat fibers are extracted, widening the gaps. During the positive pressure phase, the marinade is forced into the deep muscle layers under the pressure difference, shortening the marinade penetration path and maintaining a continuous driving force, significantly reducing marinating time while improving the tenderness and water retention of the meat products. Multiple even sprays of marinade and pulsating positive and negative pressure ensure that the meat products absorb the marinade evenly, improving the uniformity of marinating and shortening the marinating time. The air vents and liquid inlet are set at a 90-degree angle; when the marinade is sprayed, the air vents are sealed, effectively preventing liquid from directly impacting the air path and ensuring the independent and stable operation of each function.

[0015] 3. The infusion pump pumps the liquid into the tank and compresses the spring. The spring applies stable pressure to the liquid through the piston plate. The liquid flows out of the tank through the infusion hole at a constant pressure. The spray force is uniform, which not only eliminates the liquid flow fluctuation caused by pump pulse, but also maintains positive pressure in the pipeline after the external pump stops. This can fundamentally prevent the meat juice in the tumbling barrel from flowing back into the channel through the liquid outlet, solving the problems of channel blockage and contamination.

[0016] 4. During vacuuming, the mixed airflow carrying liquid droplets enters the tank via internal baffles. Due to the abrupt change in flow direction and gravity, the droplets are blocked by the baffles and collected along the inverted conical bottom. Clean gas flows around the baffles from above and is drawn away by the vacuum pump, achieving reliable liquid separation and effectively preventing liquid from entering the vacuum pump. The threaded drain cap at the bottom of the tank allows for convenient and periodic emptying of the separated residual liquid, significantly reducing maintenance costs.

[0017] 5. The support base and hydraulic cylinder allow for controlled tilting of the tumbling drum, significantly reducing the loading and unloading heights and facilitating manual or automated material handling. The spiral pattern not only enhances the extrusion and impact force on meat products but also conveys the tumbled meat products outwards during discharge. Support wheels provide auxiliary support to the tumbling drum, effectively distributing the radial load on the bearings and ensuring stable rotation. The opening of the tumbling drum utilizes an arc-shaped plate that engages with a locking plate on the sealing cap, secured by bolts on the connecting plate. This allows for quick positioning and locking of the sealing cap, ensuring reliable sealing, effortless opening and closing, and significantly reducing cleaning and preparation time between batches.

Detailed Implementation

[0020] Example 1 like Figures 1 to 10As shown, this invention discloses a tumbling and marinating device for processing seasoned meat products. The technical solution adopted includes a base plate 1, which is T-shaped. A control module 2 is fixedly installed on the top of one end of the base plate 1. A tumbling drum 3 is rotatably installed on the side of the upper end of the base plate 1. A sealing cover 4 is detachably installed in the opening at one end of the tumbling drum 3. Two arc-shaped plates 21 are fixedly connected to the end face of the opening of the tumbling drum 3. The sides of the two arc-shaped plates 21 are provided with grooves. Two clamping plates 22 are fixedly installed on the side of the sealing cover 4. The two clamping plates 22 respectively match the grooves on the two arc-shaped plates 21. Both clamping plates 22 have bolts 24 threaded into their side threaded holes. Two connecting plates 23 are fixedly installed on one side of the tumbling drum 3. Each connecting plate 23 has through holes that mate with the two bolts 24. The opening of the tumbling drum 3 is engaged with the clamping plate 22 on the sealing cover 4 via an arc-shaped plate 21, and locked in place by the bolts 24 on the connecting plates 23. This achieves quick positioning and locking of the sealing cover 4, ensuring reliable sealing, easy opening and closing, and significantly shortening the cleaning and material preparation time between batches. Four support plates 19 are fixedly installed on the top of one end of the bottom plate 1. Support wheels 20 are rotatably mounted in the grooves at the upper end of the support plate 19. The sides of the support wheels 20 contact the sides of the tumbling drum 3, providing auxiliary support to the tumbling drum 3 and effectively distributing the radial load of the bearing 12, allowing the tumbling drum 3 to maintain stable rotation. The inner wall of the tumbling drum 3 is provided with protruding spiral patterns 18. A fixing post 10 is fixedly mounted on the side of the upper end of the base plate 1. The fixing post 10 is located in the groove in the middle of the end face of the tumbling drum 3. The end face of the fixing post 10 is provided with a rubber pad that contacts the inner wall of the tumbling drum 3. The inside of the tumbling drum 3 is provided with five tumbling protrusions 5. The tumbling protrusion 5 is provided with a liquid channel 6 that connects to the groove on the end face of the tumbling drum 3. Several liquid outlet holes 7 are provided on the side of the tumbling protrusion 5, and the liquid outlet holes 7 connect to the liquid channel 6. The top of the base plate 1 is equipped with a juice adding mechanism 8 and a pulsating marinating mechanism 9. The base plate 1 is equipped with a drive mechanism 14 for driving the tumbling drum 3 to rotate. A fixing ring 11 is fixedly installed on the side of the upper end of the base plate 1. The side of the fixing ring 11 is fixedly connected to the inner side of the bearing 12. The side of the bearing 12 is fixedly connected to the side of the rotating ring 13. The end face of the rotating ring 13 is fixedly connected to the end face of the tumbling drum 3. The side of one end of the base plate 1 is rotatably connected to the opposite side of the upper end of the support base 15. The support base 15 is L-shaped. Two fixing blocks 16 are fixedly installed on the top of the other end of the support base 15 and the top of the other end of the base plate 1. The two fixing blocks 16 on the same side are rotatably connected to the sides of both ends of the hydraulic cylinder 17. The hydraulic cylinder 17 is electrically connected to the control module 2. Through the support base 15 and the hydraulic cylinder 17, the tumbling drum 3 can be tilted in a controlled manner, which significantly reduces the feeding and discharging height and facilitates manual or automated material turnover.

[0021] The drive mechanism 14 includes a first pulley 141, a belt 142, a motor 143, and a second pulley 144. The first pulley 141 is annular, and its inner side is fixedly connected to the side of the rotating ring 13. The motor 143 is fixedly mounted on the side of the base plate 1. The output shaft of the motor 143 passes through a through hole on the side of the base plate 1 and is fixedly connected to the middle of the end face of the second pulley 144. The first pulley 141 and the second pulley 144 are connected by the belt 142.

[0022] The juice addition mechanism 8 includes a storage tank 81, a one-way valve 82, an infusion pipe 83, an infusion pump 84, a pressure tank 85, an outlet pipe 86, and an infusion port 87. The storage tank 81 is fixedly installed on the top of one end of the base plate 1, and the pressure tank 85 is also installed on the top of one end of the base plate 1. The outlet on the side of the storage tank 81 is connected to one end of the infusion pipe 83, and the other end of the infusion pipe 83 is connected to the inlet on the top of the pressure tank 85. The one-way valve 82 and the infusion pump 84 are installed on the infusion pipe 83, and the infusion pump 84 is fixedly installed on the side of the storage tank 81. The infusion port 87 is located on the end face of the fixed column 10 and cooperates with the liquid channel 6. The outlet on the top of the pressure tank 85 is connected to one end of the outlet pipe 86. The other end passes through the through hole on the side of the bottom plate 1 and is connected to the infusion hole 87. The infusion pump 84 pumps the liquid into the tank 854 and compresses the spring 853. The spring 853 applies stable pressure to the liquid through the piston plate 851, so that the liquid flows out from the tank 854 through the infusion hole 87 at a constant pressure. The juice is evenly sprayed onto the surface of each piece of meat in the tumbling barrel 3, avoiding the juice from accumulating at the bottom of the barrel. This greatly improves the uniformity of the liquid distribution and the absorption efficiency. The five tumbling protrusions 5 are evenly distributed inside the tumbling barrel 3 and rotate synchronously with the tumbling barrel 3. They can play the physical impact and squeezing role of traditional tumbling protrusions, which relaxes the meat fibers, ensures that the meat is flavored inside and out, and improves the taste and quality stability of the prepared meat products. The pressure tank 85 includes a piston plate 851, a rubber ring 852, a spring 853, a tank body 854, and a base 855. The base 855 is rotatably mounted on the top of the base plate 1. The protruding part of the top of the base 855 is threadedly connected to the inner side of the lower end of the tank body 854. The piston plate 851 is slidably mounted inside the tank body 854. A rubber ring 852, which contacts the inner wall of the tank body 854, is fixedly installed in the groove on the side of the piston plate 851. The bottom of the piston plate 851 is fixedly connected to the upper end of the spring 853. The lower end contacts the top of the base 855. The infusion pump 84 pumps the liquid into the tank 854 and compresses the spring 853. The spring 853 applies stable pressure to the liquid through the piston plate 851. The liquid flows out from the tank 854 through the infusion hole 87 at a constant pressure. The spray force is uniform, which not only eliminates the liquid flow fluctuation caused by the pump pulse, but also maintains positive pressure in the pipeline after the external pump stops. This can fundamentally prevent the minced meat juice in the tumbling barrel 3 from flowing back into the channel through the liquid outlet 7, thus solving the problems of channel blockage and contamination.

[0023] The pulsating marinating mechanism 9 includes a vacuum pump 91, a solenoid valve 92, an air pump 93, an air pipe 94, an air vent 95, a pressure gauge 96, and a liquid removal tank 97. The vacuum pump 91 and air pump 93 are fixedly mounted on the top of the base plate 1. The air vent 95 is located on the end face of the fixed column 10 and mates with the liquid channel 6. The angle between the air vent 95 and the liquid delivery port 87 is 90 degrees. The air pipe 94 is Y-shaped, with its lower ends connected to the air inlet of the vacuum pump 91 and the air outlet of the air pump 93, respectively. Each end is equipped with a solenoid valve 92. The upper end of the air pipe 94 passes through a through hole on the side of the base plate 1 and connects to the air hole 95. A pressure gauge 96 and a liquid removal tank 97 are installed on one end of the upper side of the air pipe 94. The infusion pump 84, vacuum pump 91, solenoid valve 92, air pump 93, and pressure gauge 96 are electrically connected to the control module 2. During the tumbling process, the solenoid valve 92 switches, causing the air pump 93 and vacuum pump 91 to alternately extract and supply air into the tumbling drum 3, so that the environment inside the tumbling drum 3 changes periodically between vacuum negative pressure and air pressure positive pressure. In the negative pressure stage, air and excess liquid between meat fibers are extracted, and the gaps expand; in the positive pressure stage, the juice is forced into the deep muscle layer under the drive of the pressure difference, which shortens the juice penetration path and sustains the driving force, significantly shortening the marinating time, while improving the tenderness and water retention of the meat products. The air hole 95 and the infusion hole 87 are set at a 90-degree angle. When the juice is sprayed out, the air hole 95 is in a sealed state, which effectively prevents the liquid from directly rushing into the air passage and ensures the independent and stable function of each.

[0024] The liquid removal tank 97 includes a baffle 971, a tank body 972, and a drain cover 973. An L-shaped baffle 971 is fixedly connected to the inner wall of the upper end of the tank body 972. The baffle 971 is located between the air inlet and outlet of the tank body 972. The lower end of the tank body 972 is inverted conical, and a drain cover 973 is threadedly connected to the bottom. During vacuuming, the mixed airflow carrying liquid droplets enters the tank body 972 through the baffle 971 inside the liquid removal tank 97. Due to the sudden change in flow direction and gravity, the droplets are blocked by the baffle 971 and collected along the bottom of the inverted conical shape. Clean gas bypasses the baffle 971 from above and is drawn away by the vacuum pump 91, achieving reliable separation of the liquid and effectively preventing liquid from entering the vacuum pump 91. The threaded drain cover 973 at the bottom of the tank body 972 allows for convenient and periodic emptying of the separated residual liquid, significantly reducing maintenance costs.

[0025] The working principle of this invention is as follows: The control module 2 activates the hydraulic cylinder 17, causing the base plate 1 to rotate around the upper end of the support base 15, tilting the tumbling drum 3 to an angle conducive to loading. Meat products are placed inside the tumbling drum 3, and then the sealing cover 4 is positioned at the opening of the tumbling drum 3. Rotating the sealing cover 4 causes the two clamping plates 22 to enter the grooves of the arc-shaped plate 21, and the bolts 24 are tightened so that they pass through the through holes of the connecting plate 23 for quick locking. Subsequently, the hydraulic cylinder 17 resets, restoring the tumbling drum 3 to a horizontal position. The control module 2 then controls the motor 143 to operate, driving the second pulley 14. 4. Rotation: The first pulley 141 is driven to rotate by the belt 142. The first pulley 141 drives the rotating ring 13 and the tumbling drum 3 fixed thereto to rotate smoothly around the fixed ring 11 and the bearing 12. The support wheel 20 and support plate 19 on the side of the tumbling drum 3 provide auxiliary support. The spiral pattern 18 and tumbling protrusions 5 on the inner wall of the tumbling drum 3 continuously impact and squeeze the meat products, so as to relax the muscle fibers. During tumbling and marinating, the infusion pump 84 is controlled by the control module 2. The infusion pump 84 pumps the juice in the storage tank 81 into the pressure tank 85 through the infusion pipe 83 and the one-way valve 82. Inside 854, the liquid pushes the piston plate 851 to compress the spring 853, and the rubber ring 852 seals to maintain a constant pressure inside the tank. When the tumbling drum 3 rotates, when the end of the liquid channel 6 aligns with the inlet hole 87 on the fixed column 10, the elasticity of the spring 853 causes the liquid to be transported from the outlet pipe 86 to the inlet hole 87 on the end face of the fixed column 10, and then into the liquid channel 6 in the groove on the end face of the tumbling drum 3. Finally, it is evenly sprayed onto the surface of the meat product from the multiple outlet holes 7 on the sides of the five tumbling protrusions 5. During the tumbling process, the vacuum pump 91 or the air pump 93 is alternately turned on by the control module 2. The solenoid valve 92 causes the pressure inside the tumbling drum 3 to change periodically. During the negative pressure stage, when the tumbling drum 3 rotates, when the air hole 95 is aligned with the liquid channel 6, the air inside the tumbling drum is extracted through the air pipe 94, air hole 95, liquid channel 6 and liquid outlet 7, causing the gaps between meat fibers to expand. During the positive pressure stage, air is pumped in to force the material into the deep layer of the meat. The pressure gauge 96 monitors the pressure in real time. At the same time, the extracted mixed gas enters the liquid removal tank 97. Inside the tank body 972, the liquid is blocked by the baffle 971 and separated. The clean gas is extracted by the vacuum pump 91. The separated residual liquid can be discharged periodically through the drain cover 973.After marinating, the hydraulic cylinder 17 is restarted to tilt the tumbling drum 3, and the sealing cover 4 is opened to unload the material. Throughout the process, the rubber pad on the end face of the fixing column 10 remains in contact with the inner wall of the tumbling drum 3 to ensure reliable sealing between the liquid and the air pressure channel. Since the tumbling protrusion 5 and its internal liquid channel 6 are each provided with 5, and the angle between the air hole 95 and the liquid inlet 87 is 90 degrees, when the tumbling drum 3 rotates, the liquid channel 6 will alternately align with the liquid inlet 87 and the air hole 95, separating the timing of air extraction and air supply from the timing of liquid spraying, thereby preventing a large amount of liquid backflow. After tumbling, the bolt 24 is tightened to disengage from the through hole on the connecting plate 23, and the sealing cover 4 is rotated in the opposite direction to allow the clamping plate 22 to rotate out of the groove of the arc plate 21. The sealing cover 4 is then removed, and the tumbled meat products can be taken out.
