Description

Technical Field

[0001] This invention relates to the field of meat processing technology, specifically to an ultrasonic synergistic sterilization device for meat products. Background Technology

[0002] Meat product sterilization equipment is a specialized device that uses physical, chemical, and biological methods to kill and inhibit pathogenic bacteria, spoilage bacteria, parasites, and other harmful microorganisms in meat products, while preserving the quality of meat products to the maximum extent. Its core purpose is to extend the shelf life of meat products and ensure food safety. It is widely used in various meat product processing scenarios such as sausages, hams, bacon, and braised meats. It can specifically eliminate pathogenic bacteria such as Salmonella, Staphylococcus aureus, and Clostridium botulinum, as well as molds and yeasts that cause meat product spoilage, thereby reducing food safety risks.

[0003] Existing traditional meat product sterilization methods mostly rely on high-temperature heating, which can easily lead to poor meat quality and loss of nutrients, and have limited effect on killing deep bacteria. On the other hand, ultrasonic sterilization alone has problems such as uneven sterilization and long time required, making it difficult to meet the high-efficiency sterilization requirements of large-scale meat product production, thereby reducing the working efficiency of meat product sterilization equipment.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. After the meat products are sealed inside the sterilization chamber, a double-layer ultrasonic transducer array is used to evenly distribute the transducers on the inner wall of the sterilization chamber, ensuring uniform wave reception in all parts of the meat products. In addition, since the sterilization chamber has a built-in pressure relief valve, which is a mature existing technology, the temperature and pressure sensors work together with the sterilization environment parameters in the external control system to adapt to the sterilization needs of different types of meat products. The drive motor is then activated to rotate the meat products inside the sterilization chamber, achieving comprehensive sterilization of the meat products. This solves the problem that traditional meat product sterilization methods in the past could not meet the high-efficiency sterilization requirements of large-scale meat product production and reduced the sterilization efficiency of meat products.

[0017] 2. When meat products need to be sterilized, a certain amount of water is delivered into the sterilization chamber, and the amount of meat products in multiple storage compartments is fully loaded. The meat products are positioned by two sets of perforated plates, and the perforated plate at the top is rotated into the storage compartment by a certain angle under the action of the spring and coil spring connected to it, so as to facilitate the subsequent ultrasonic sterilization of the meat products.

[0018] 3. After the meat products are stored in the storage compartment, the storage compartment can be indirectly connected to the moving frame. The moving frame pushes multiple storage compartments into the interior of the sterilization chamber. When the sealing plate moves forward to the position where its outer surface completely overlaps with the inner wall of the sterilization chamber, the sterilization chamber is sealed, and the multiple storage compartments are completely inside the sterilization chamber, thus realizing the automatic conveying of meat products.

[0023] In this embodiment, after the meat products are sealed inside the sterilization chamber body 301, which consists of a temperature control device, a pressure control device, and a drainage device (existing mature technology, not described in detail here), the two first electric push rods 305 are activated by an external control system to extend, thereby driving the two connected lifting frames 306 to move downwards into the water. Multiple telescopic tubes 304 support the lifting frames 306, making their movement more stable. Then, multiple ultrasonic sterilizers 312 are activated by the external control system, combined with the water supplied to the sterilization chamber body 301, to sterilize the meat products. For example... Figure 8As shown, multiple ultrasonic sterilizers 312 are arranged on both the top and bottom surfaces of the sterilization chamber body 301. By employing a double-layer ultrasonic transducer array layout, evenly distributed within the inner wall of the sterilization chamber body 301, uniform wave reception is ensured across all parts of the meat product. Furthermore, since the sterilization chamber body 301 has a built-in pressure relief valve, a mature existing technology, the temperature sensor 314 and pressure sensor 313 work together, in conjunction with sterilization environment parameters in the external control system, to adapt to the sterilization needs of different types of meat products. The ultrasonic sterilizers 312 generate high-frequency sound waves, creating a cavitation effect in the water. The high-frequency vibration of the ultrasound causes tiny bubbles to form in the water. These bubbles rapidly grow and collapse under the action of the ultrasound, generating powerful shock waves and localized high temperatures, thereby destroying the cell walls, cell membranes, and other structures of microorganisms in the meat product, achieving sterilization. The temperature sensor 314 monitors the water temperature inside the sterilization chamber in real time, and the external control system has preset upper and lower temperature limits. The lower limit is reached when the temperature reaches the lower limit. When this limit is reached, the external control system activates the heating wire in the temperature control device section of the sterilization chamber 301 to heat the water inside. When the upper limit is reached, the external control system stops the heating wire, maintaining the water temperature within a suitable sterilization range. The pressure sensor 313 monitors the pressure changes within the sterilization chamber 301 in real time. In scenarios requiring pressure-assisted sterilization, such as high-pressure ultrasonic sterilization, the pressure sensor 313 ensures the sterilization process is carried out at the optimal pressure. The external control system adjusts the pressure relief valve in the sterilization chamber 301 based on the feedback from the pressure sensor 313, maintaining the pressure within the set range. Appropriate pressure enhances the propagation of ultrasonic waves, further improving the cavitation effect, and also helps maintain a stable environment within the sterilization chamber, ensuring consistent sterilization results. This achieves comprehensive and efficient sterilization of meat products in the water. Figure 12As shown, the perforated plates 403 positioned above are tilted downwards at a certain angle due to the elastic force of the springs 404. This tilted perforated plate 403 alters the propagation path of the ultrasonic waves, reducing energy loss when the waves encounter plane reflection during propagation. When ultrasonic waves are incident perpendicularly onto a plane, specular reflection easily occurs, and some energy is reflected back towards the transducer. However, the tilted perforations 403 allow the ultrasonic waves to be incident at a certain angle, enabling more sound energy to penetrate the perforated plate and enter the meat product, thus improving the utilization rate of the ultrasonic waves and further enhancing the processing efficiency of the meat product. In addition to disinfecting the meat products, to ensure more comprehensive sterilization, an external control system activates the drive motor 310, causing its drive shaft to rotate the connected gear 308. This, in turn, rotates the corresponding rotating rod 307. Simultaneously, the rotation of the gear 308 drives the corresponding conveyor belt 311, which in turn drives multiple gears 308 and another conveyor belt 311, causing multiple rotating rods 307 to rotate. The rotation of these multiple rotating rods 307 then causes multiple storage compartments 401 to rotate. This process rotates the meat products placed below to the top, and the perforated plate 403, originally placed above, also rotates to the top. At this point, its top is no longer squeezed by the meat products, and it will rotate a certain angle into the storage compartment 401 under the elastic action of the four springs 404 connected to it, thereby enhancing the sterilization of the meat products. After the perforated plate 403, originally placed above, rotates to the bottom of the storage compartment 401, it will be squeezed by the meat products and rotate downwards to the position where it contacts the inner wall of the protective frame 409, becoming the bottom support of the storage compartment 401. Through the cooperation between the sterilization component 3 and the protective component 4, comprehensive sterilization of the meat products is achieved. Furthermore, by adopting a double-layer ultrasonic transducer array layout, the sterilization efficiency of the meat products is further improved, solving the problem that traditional meat product sterilization in the prior art cannot meet the high-efficiency sterilization requirements of large-scale meat product production and reduces the sterilization efficiency of meat products.

[0024] like Figures 1-15As shown, an ultrasonic synergistic sterilization device for meat products includes a connecting base plate 1. A conveying component 2 for conveying meat products is disposed on the top of the connecting base plate 1 near one edge, and a sterilization component 3 for processing the meat products is disposed on the top of the connecting base plate 1 near the other edge. Multiple protective components 4 are disposed inside the sterilization component 3. The sterilization component 3 includes a sterilization chamber body 301. Multiple ultrasonic sterilizers 312 are disposed between the opposing inner walls of the sterilization chamber body 301 via auxiliary plates. Lifting frames 306 are disposed on the opposing inner walls of the sterilization chamber body 301. Multiple rotating rods 307 are rotatably connected to the inner walls of two lifting frames 306. Each of the multiple protective components 4 includes a storage compartment 401. Two perforated plates 403 are provided between the inner walls of each storage compartment 401. Protective frames 409 for positioning the perforated plates 403 are slidably connected to the inner walls of each storage compartment 401. After meat products are stored in each storage compartment 401, they can be conveyed to the interior of the sterilization chamber body 301 via the conveying assembly 2. The extension of the two first electric push rods 305 will move the storage compartments 401 downwards into the sterilization chamber body 301, where they are sterilized by the multiple ultrasonic sterilizers 312 located above and below. The sterilization chamber body 301 can also rotate with the cooperation of multiple rotating rods 307. The conveying assembly 2 includes a support plate 201, the top of which rests against... Mounting brackets 202 are fixedly connected to both sides of the edge. A forward / reverse motor 203 is fixedly connected to the outer surface of one mounting bracket 202 by screws. A lead screw 204 is fixedly connected to the output end of the forward / reverse motor 203. A limit tube 205 is fixed between the opposing inner walls of the other mounting bracket 202. A sliding rod 206 is fixed to the top of both mounting brackets 202. A movable bracket 207 is threaded onto the outer surface of the lead screw 204. A positioning rod 208 is fixedly installed on the outer surface of the movable bracket 207. A sealing plate 209 is fixedly connected to one end of the positioning rod 208. A cylinder 210 is located near the center of the outer surface of the sealing plate 209. A mounting block 211 is fixedly connected to one end of the cylinder 210. The inner wall of 11 is provided with a bidirectional electric telescopic rod 212, and extension rods 213 are fixed at both ends of the bidirectional electric telescopic rod 212. The bottom of the support plate 201 is fixedly connected to the top of the connecting base plate 1. Both ends of the screw 204 are movably extended to the outside of one of the mounting brackets 202. The outer surfaces of the two sides of the sealing plate 209 slide against the inner walls of the two mounting brackets 202 respectively. The outer surfaces of the two sides of the sealing plate 209 slide against the inner walls of the two sliding grooves 302 respectively. The outer surfaces of the two sides of the moving frame 207 slide against the inner walls of the two mounting brackets 202 respectively. The inner wall of the moving frame 207 slides against the outer surface of the limiting tube 205. The outer diameter of the sealing plate 209 matches the inner diameter of the sterilization chamber body 301.

[0025] In this embodiment, when meat products need to be sterilized, the external hot water pipe is first connected to one end of the conveying pipe 5 by a sealing ring. The sealing ring is made of rubber material with sealing properties, thereby delivering a fixed amount of external water to the inside of the sterilization chamber body 301. At this time, multiple storage compartments 401 are placed on top of the support plate 201, and two connecting rods 303 are respectively embedded in the two corresponding limiting tubes 205. The operator can then rotate the perforated plate 403 on the upper part upwards to put a fixed amount of meat products into each storage compartment 401, thereby ensuring that the meat products are sterilized. Figure 14 Each perforated plate 403 located on the lower side of the storage compartment 401 is squeezed and rotates downwards. After the meat products in multiple storage compartments 401 have been added, the staff can release the restraints on the perforated plates 403 located on the upper side. This allows the perforated plates 403 to rotate towards the storage compartment 401 under the elastic action of multiple springs 404 connected to them, until they return to their original positions. Then, multiple second electric push rods 407 can be simultaneously activated via an external control system to shorten them, thereby driving their corresponding movable frames 408 towards the storage compartment 401. This allows the corresponding protective frames 409 to be inserted into the interior of their respective storage compartments 401. For example... Figure 15 As shown, the end face of the protective frame 409 is arc-shaped, and the end face of the part of the perforated plate 403 that overlaps with the protective frame 409 in the vertical direction is also arc-shaped. This is to facilitate the movement of the protective frame 409. When the protective frame 409 moves to a position that contacts the outer surface of the perforated plate 403 located below, it can push the perforated plate 403 below to rotate upward by a certain angle until the bottom of the perforated plate 403 is tightly attached to the inner wall of the protective frame 409, thereby achieving the limitation of the two perforated plates 403 in the storage compartment 401. At this time, the perforated plate 403 located above is rotated into the storage compartment 401 by a certain angle under the action of the spring 404 and the coil spring 406 connected to it, which facilitates the subsequent ultrasonic sterilization of meat products.

[0026] like Figures 1-15As shown, an ultrasonic synergistic sterilization device for meat products includes a connecting base plate 1. A conveying component 2 for conveying meat products is disposed on the top of the connecting base plate 1 near one edge, and a sterilization component 3 for processing the meat products is disposed on the top of the connecting base plate 1 near the other edge. Multiple protective components 4 are disposed inside the sterilization component 3. The sterilization component 3 includes a sterilization chamber body 301.

Lifting frames 306 are disposed on the opposing inner walls of the sterilization chamber body 301. Multiple rotating rods 307 are rotatably connected to the inner walls of two lifting frames 306. Each of the multiple protective components 4 includes a storage compartment 401. Two perforated plates 403 are provided between the inner walls of each storage compartment 401. Protective frames 409 for positioning the perforated plates 403 are slidably connected to the inner walls of each storage compartment 401. After meat products are stored in each storage compartment 401, they can be conveyed to the interior of the sterilization chamber body 301 via the conveying assembly 2. The extension of the two first electric push rods 305 will move the storage compartments 401 downwards into the sterilization chamber body 301, where they are sterilized by the multiple ultrasonic sterilizers 312 located above and below. The sterilization chamber body 301 can also rotate with the cooperation of multiple rotating rods 307. The conveying assembly 2 includes a support plate 201, the top of which rests against...

The inner wall of 11 is provided with a bidirectional electric telescopic rod 212, and extension rods 213 are fixed at both ends of the bidirectional electric telescopic rod 212. The bottom of the support plate 201 is fixedly connected to the top of the connecting base plate 1. Both ends of the screw 204 are movably extended to the outside of one of the mounting brackets 202. The outer surfaces of the two sides of the sealing plate 209 slide against the inner walls of the two mounting brackets 202 respectively. The outer surfaces of the two sides of the sealing plate 209 slide against the inner walls of the two sliding grooves 302 respectively. The outer surfaces of the two sides of the moving frame 207 slide against the inner walls of the two mounting brackets 202 respectively. The inner wall of the moving frame 207 slides against the outer surface of the limiting tube 205. The outer diameter of the sealing plate 209 matches the inner diameter of the sterilization chamber body 301.

[0027] In this embodiment, the bidirectional electric telescopic rod 212 is activated by an external control system, causing it to extend to both sides, thereby pushing... Figure 6The two extension rods 213 shown move outward from the mounting block 211, and then into the slot 410, where, as Figure 9 As shown, the internal cross-section of the slot 410 is cross-shaped, which is intended to facilitate the limiting of the two extension rods 213. After the two extension rods 213 are positioned, the forward and reverse motors 203 can be started by the external control system, which drives the lead screw 204 to rotate, thereby driving the moving frame 207 to move forward. The limiting tube 205 limits the moving frame 207, thereby pushing the sealing plate 209 to move forward, which in turn causes the mounting block 211 to move forward, which in turn pushes the corresponding storage compartment 401 to move forward, and pushes the two connecting rods 303. Moving forward, the remaining storage compartments 401 are driven by the two connecting rods 303 to move into the sterilization chamber body 301. When the sealing plate 209 moves forward to the position where its outer surface completely overlaps with the inner wall of the sterilization chamber body 301, the sterilization chamber body 301 is sealed. The outer ring of the sealing plate 209 is made of rubber material with a sealing function. At this time, the two connecting rods 303 have also moved completely into the two sliding grooves 302, and the multiple storage compartments 401 are completely inside the sterilization chamber body 301, as shown in the figure. Figure 1 and Figure 2 As shown, the bidirectional electric telescopic rod 212 can then be activated again to shorten it, thereby driving the two extension rods 213 to move into the mounting block 211. Then the cylinder 210 can be activated to shorten it, thereby driving the mounting block 211 and the two extension rods 213 to move away from the storage compartment 401 until the mounting block 211 is completely removed from the inside of the slot 410, thus realizing the automatic conveying of meat products.

[0028] like Figures 1-15As shown, an ultrasonic synergistic sterilization device for meat products includes a connecting base plate 1. A conveying component 2 for conveying meat products is disposed on the top of the connecting base plate 1 near one edge, and a sterilization component 3 for processing the meat products is disposed on the top of the connecting base plate 1 near the other edge. Multiple protective components 4 are disposed inside the sterilization component 3. The sterilization component 3 includes a sterilization chamber body 301. Multiple ultrasonic sterilizers 312 are disposed between the relatively inner walls of the sterilization chamber body 301 through auxiliary plates. Lifting frames 306 are disposed between the relatively inner walls of the sterilization chamber body 301. Multiple rotating rods 307 are rotatably connected to the inner walls of two lifting frames 306. Multiple protective components are also present. Each of the four components includes a storage compartment 401. Two perforated plates 403 are provided between the inner walls of the multiple storage compartments 401. The inner walls of the multiple storage compartments 401 are slidably connected with protective frames 409 for positioning the perforated plates 403. After the meat products are stored in the multiple storage compartments 401, they can be transported to the interior of the sterilization chamber body 301 by the conveying component 2. When the two first electric push rods 305 extend, they will drive the multiple storage compartments 401 to move downward into the interior of the sterilization chamber body 301. Sterilization is carried out under the action of multiple ultrasonic sterilizers 312 located above and below. The multiple sterilization chamber bodies 301 can also rotate with the cooperation of multiple rotating rods 307.

[0029] In this embodiment, after the meat products have been sterilized, the drive motor 310 can be started in reverse, causing the slot 410 in the outermost storage compartment 401 to rotate to the upper side. Then, the two first electric push rods 305 can be started again to shorten them, thereby driving the lifting frame 306 to move upward, thus resetting the multiple storage compartments 401. The bottom of the storage compartments 401 is flush with the bottom of the sealing plate 209 and above the water surface in the sterilization chamber body 301. Then, the cylinder 210 can be started again to extend it, thereby moving the mounting block 2... 11. Insert the mounting block 211 into the slot 410 again. At the same time, start the bidirectional electric telescopic rod 212 again to extend it to both sides, so that both extension rods 213 are inserted into the slot 410. This connects the mounting block 211 with the outermost storage compartment 401. Then, start the forward and reverse motor 203 in reverse to drive the lead screw 204 to rotate in the opposite direction. This moves the multiple storage compartments 401 to the top of the support plate 201, and the sterilized meat products are moved to the top of the support plate 201, thus achieving automatic sterilization of the meat products.

[0030] The usage and working principle of this device are as follows: When meat products need to be sterilized, firstly, connect one end of the external hot water pipe to the conveying pipe 5 using a sealing ring, thereby delivering a fixed amount of external water to the inside of the sterilization chamber body 301. At this time, multiple storage compartments 401 are placed on top of the support plate 201, and two connecting rods 303 are respectively embedded in the two corresponding limiting tubes 205. The operator can then rotate the perforated plate 403 on the upper part upwards to put a fixed amount of meat products into each storage compartment 401, thus ensuring that the meat products are sterilized. Figure 14 Each perforated plate 403 located on the lower side of the storage compartment 401 is squeezed and rotates downwards. After the meat products in multiple storage compartments 401 have been added, the staff can release the restraints on the perforated plates 403 located on the upper side. This allows the perforated plates 403 to rotate towards the storage compartment 401 under the elastic action of multiple springs 404 connected to them, until they return to their original positions. Then, multiple second electric push rods 407 can be simultaneously activated via an external control system to shorten them, thereby driving their corresponding movable frames 408 towards the storage compartment 401. This allows the corresponding protective frames 409 to be inserted into the interior of their respective storage compartments 401. For example... Figure 15 As shown, the end face of the protective frame 409 is arc-shaped, and the end face of the portion of the perforated plate 403 that overlaps with the protective frame 409 in the vertical direction is also arc-shaped. When the protective frame 409 moves to a position where it contacts the outer surface of the perforated plate 403 located below, it can push the perforated plate 403 below to rotate upwards by a certain angle until the bottom of the perforated plate 403 is tightly attached to the inner wall of the protective frame 409, thereby achieving the limitation of the two perforated plates 403 in the storage compartment 401. At this time, the perforated plate 403 located above is rotated inwards by a certain angle by the spring 404 and coil spring 406 connected to it, facilitating the subsequent ultrasonic sterilization of meat products. Then, the bidirectional electric telescopic rod 212 can be activated through the external control system to extend it to both sides, thereby pushing the perforated plate 403 upwards by a certain angle. Figure 6 The two extension rods 213 shown move outward from the mounting block 211, and then into the slot 410, where, as Figure 9As shown, the internal cross-section of the slot 410 is cross-shaped. After the two extension rods 213 are positioned, the forward and reverse motors 203 can be started by the external control system, causing the lead screw 204 to rotate, which in turn drives the moving frame 207 to move forward, thereby pushing the sealing plate 209 forward, which in turn causes the mounting block 211 to move forward, which in turn pushes the corresponding storage compartment 401 forward, pushing the two connecting rods 303 forward, which in turn drives the remaining multiple storage compartments 401 to move into the sterilization chamber body 301 under the action of the two connecting rods 303. When the sealing plate 209 moves forward to the position where its outer surface completely overlaps with the inner wall of the sterilization chamber body 301, at this time, the two connecting rods 303 have also moved completely into the interior of the two sliding grooves 302, and the multiple storage compartments 401 are also completely inside the sterilization chamber body 301, as shown in the figure. Figure 1 and Figure 2 As shown, the bidirectional electric telescopic rod 212 can then be activated again to shorten it, thereby driving the two extension rods 213 to move into the mounting block 211. Then, the cylinder 210 can be activated to shorten it, thereby driving the mounting block 211 and the two extension rods 213 to move away from the storage compartment 401 until the mounting block 211 is completely removed from the slot 410. After the meat products are sealed inside the sterilization chamber body 301, the two first electric push rods 305 are activated through the external control system to extend them, thereby driving the two lifting frames 306 connected to them to move downward into the water. Then, multiple ultrasonic sterilizers 312 can be activated through the external control system, combined with the water source supplied to the sterilization chamber body 301, to sterilize the meat products. Among them, such as Figure 8As shown, multiple ultrasonic sterilizers 312 are arranged on both the top and bottom surfaces of the sterilization chamber body 301. By employing a double-layer ultrasonic transducer array layout, evenly distributed within the inner wall of the sterilization chamber body 301, uniform wave reception is ensured across all parts of the meat product. Through the cooperation between the temperature sensor 314 and the pressure sensor 313, and in conjunction with the sterilization environment parameters in the external control system, the sterilization requirements of different types of meat products are adapted. The ultrasonic sterilizers 312 generate high-frequency sound waves, creating a cavitation effect in the water. The high-frequency vibration of the ultrasonic waves causes tiny bubbles to form in the water. These bubbles rapidly grow and collapse under the action of the ultrasonic waves, generating powerful shock waves and localized high temperatures, thereby destroying the cell walls, cell membranes, and other structures of microorganisms in the meat product, achieving the purpose of sterilization. The temperature sensor... 314 The water temperature inside the sterilization chamber is monitored in real time. The external control system has preset upper and lower temperature limits. When the temperature reaches the lower limit, the external control system will activate the heating wire in the temperature control device section of the sterilization chamber body 301 to heat the water inside the sterilization chamber body 301 and increase the water temperature. When the temperature reaches the upper limit, the external control system will stop the heating wire to maintain the water temperature within a suitable sterilization temperature range. The pressure sensor 313 can monitor the pressure changes inside the sterilization chamber body 301 in real time. In some scenarios that require pressure-assisted sterilization, such as high-pressure ultrasonic sterilization, the pressure sensor 313 can ensure that the sterilization process is carried out under optimal pressure. The external control system can adjust the pressure relief valve in the sterilization chamber body 301 based on the information fed back by the pressure sensor 313. Figure 12 As shown, the perforated plates 403 positioned above are tilted downwards at a certain angle due to the elastic force of the springs 404. This tilted perforated plates 403 alter the propagation path of the ultrasonic waves, reducing energy loss when the waves encounter plane reflections during propagation. Then, the external control system activates the drive motor 310, causing its drive shaft to rotate the gear 308 connected to it. This, in turn, rotates the corresponding rotating rod 307. Simultaneously, the rotation of the gear 308 drives the corresponding conveyor belt 311 to rotate, thereby driving multiple gears 308 and another conveyor belt 311 to rotate. This causes multiple rotating rods 307 to rotate, resulting in the rotation of multiple storage compartments 401. This causes the meat products placed below to rotate to the top, and the perforated plate 403, originally placed above, also rotates to the top. At this point, its top is no longer compressed by the meat products, and it rotates at a certain angle into the storage compartment 401 under the elastic action of the four springs 404 connected to it, thus enhancing the sterilization of the meat products. The perforated plate 403, originally placed above, rotates to the bottom of the storage compartment 401 and is then compressed by the meat products, rotating downwards to contact the inner wall of the protective frame 409, becoming the bottom support of the storage compartment 401. After the meat products are sterilized, the drive motor 310 can be started in reverse, causing the slot 410 in the outermost storage compartment 401 to rotate to the top. Then, the two first electric push rods 305 can be activated again, shortening them and causing the lifting frame 306 to move upwards, thereby resetting the multiple storage compartments 401. The bottom is flush with the bottom of the sealing plate 209 and above the water surface in the sterilization chamber body 301. Then, the cylinder 210 can be activated again to extend it, thereby inserting the mounting block 211 back into the slot 410. At the same time, the bidirectional electric telescopic rod 212 is activated again to extend it to both sides, so that both extension rods 213 are inserted into the slot 410. Then, the forward and reverse motor 203 can be activated in reverse to drive the lead screw 204 to rotate in the opposite direction, thereby moving the multiple storage compartments 401 to the top of the support plate 201. The sterilized meat products are then moved to the top of the support plate 201. The external control system is electrically connected to the forward and reverse motor 203, the cylinder 210, the bidirectional electric telescopic rod 212, the first electric push rod 305, the drive motor 310, the ultrasonic sterilizer 312, the pressure sensor 313, the temperature sensor 314, and the second electric push rod 407.
