[0002] A vacuum kneading drum typically consists of a sealed drum made of food-grade stainless steel with an internal spiral guide plate. Its main function is to tumble, knead, and beat meat under vacuum and negative pressure to accelerate the marinating process and improve meat quality. It solves the pain points of traditional meat processing and has become a key piece of equipment in modern meat production. Its core value lies in efficient penetration, quality improvement, and cost optimization. It is widely used in the industrial production of high-value-added meat products such as ham, sausage, and reconstituted meat, and is therefore an indispensable piece of equipment in modern meat processing.

[0003] Existing vacuum kneading drums for meat processing include a drum, a vacuum system, a drive system, a control system, and a side wall sliding door. Generally, when kneading marinated meat, the meat is loaded into the drum by opening the sliding door, then the door is closed. Next, the vacuum pump is started to draw air to the set pressure and expel the air to promote meat penetration. The side wall sliding door is usually connected to the drum wall by a hinge or other structure. However, after long-term use, the hinge connection structure is prone to slight loosening, causing the sealing position of the sliding door to shift, resulting in a decrease in sealing performance and affecting the vacuum extraction effect inside the drum. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum kneading drum structure for meat processing, in order to solve the problem mentioned in the background art that the side wall movable door is generally connected to the drum wall through a structure such as a hinge. However, after long-term use, the hinge connection structure is prone to slight loosening, causing the sealing position of the movable door to shift, resulting in a decrease in sealing performance and affecting the vacuum extraction effect inside the drum.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum kneading drum structure for meat processing. This kneading drum structure is positioned above a base and includes a roller, a mounting portion, and a sealing portion.

A compression spring is sleeved on the outer side of the telescopic short rod. An arc-shaped pressure plate is fixedly connected to the outer wall of the insert plate.

[0006] By adopting the above technical solutions, a sliding door cover structure is constructed.

[0007] Preferably, the mounting part includes a sliding frame fixedly connected to the outer wall of the roller. The sliding frame has two sets of sliding rails inside, and each set of sliding rails has an insertion groove on its top surface. The insertion groove is connected to the outside of the sliding frame.

[0008] By adopting the above technical solution, and in conjunction with the sliding installation of the sealing part,

[0009] Preferably, the insert plate is provided in two sets, and the two sets of insert plates are symmetrically distributed on the vertical central axis of the movable door. The top of the insert plate extends into the interior of the insertion groove and forms an insertion structure with the insertion groove.

[0010] By adopting the above technical solution, both sides of the movable door are fixed.

[0011] Preferably, an adsorption magnet is fixedly connected to the side of the movable door near the inside of the sliding track, and an iron sheet is fixedly connected to the inner wall of the sliding track near the movable door, and the adsorption magnet and the iron sheet are attracted and adhered to each other.

[0012] By adopting the above technical solution, the mutual attraction between the magnet and the iron sheet can be used to assist in the installation of the movable door.

[0013] Preferably, a sealing gasket is fixedly connected to the inner wall of the movable door near the roller, and the side of the sealing gasket away from the movable door is in close contact with the outer wall of the roller.

[0027] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0028] Example 1

[0029] Please see Figure 1-5 This embodiment provides a technical solution for a vacuum kneading drum structure for meat processing: A vacuum kneading drum structure for meat processing is used to be installed above a base 1, including a roller 2, a mounting part 3, and a sealing part 4. The system equipment inside the vacuum kneading drum structure is connected to an external power supply via a power line and to an external control panel via a data line. The vacuum kneading drum structure also includes a vacuum system, a drive system, a control system, and a kneading plate structure. The vacuum system includes a vacuum pump and a pneumatic valve. The vacuum pump draws water from inside the drum through mechanical or water circulation. Air is used to maintain the vacuum level. Pneumatic valves are used to control the opening and closing of the vacuum pipeline to prevent air backflow. The drive system includes a variable frequency motor, a transmission device such as a chain, gear or belt drive, etc., which mainly provides a power source for the kneading plate structure. The variable frequency motor also supports speed adjustment. All of the above are existing technologies. The roller 2 is located above the base 1. The roller 2 has a feed port on its outer wall near the mounting part 3. The meat is put in or taken out by opening and closing the sealing part 4. Then, the drive system drives the kneading plate to knead the meat.

[0030] Example 2

[0031] Please see Figure 1-5 The mounting part 3 is located on the outside of the roller 2. The mounting part 3 includes a sliding frame 301 connected to the outer wall of the roller 2 by screws. The sliding frame 301 has a U-shaped structure and is located on the outside of the feed inlet. Two sets of sliding tracks 302 are provided inside the sliding frame 301. Both ends of the movable door 401 extend into the interior of the two sets of sliding tracks 302, and both ends of the movable door 401 slide against the inner side of the sliding tracks 302. Therefore, the movable door 401 forms a sliding door cover structure on the outside of the roller 2, reducing... In case the sealing position of the movable door 401 is offset, the top surface of both sets of sliding tracks 302 is provided with insertion grooves 303. The insertion grooves 303 are connected to the outside of the sliding frame 301. The shape and size of the insertion grooves 303 are the same as those of the insertion plates 403. There are two sets of insertion plates 403. The two sets of insertion plates 403 are symmetrically distributed on the vertical central axis of the movable door 401. The top of the insertion plate 403 extends into the interior of the insertion groove 303 and forms an insertion structure with the insertion groove 303. The sealing part 4 is provided inside the mounting part 3.

[0032] The sealing part 4 includes a movable door 401 slidably disposed inside the mounting part 3. Movable grooves 402 are provided on both outer side walls of the movable door 401. An insert plate 403 is disposed inside the movable groove 402. A telescopic short rod 404 is disposed between the insert plate 403 and the inner side wall of the movable groove 402. The top end of the telescopic short rod 404 is slidably connected to the bottom surface of the insert plate 403, and the bottom end of the telescopic short rod 404 is connected to the top surface inside the movable groove 402 by screws. A compression spring 405 is sleeved on the outer side of the telescopic short rod 404, and one end of the compression spring 405 is connected to the top surface inside the movable groove 402 by screws. The other end is connected to the bottom surface of the insert plate 403 by screws. Several sets of telescopic short rods 404 and compression springs 405 are provided, and each set of telescopic short rods 404 and compression springs 405 are distributed at equal intervals along the length direction of the movable door 401. When the insert plate 403 is inserted into the insertion slot 303, the compression spring 405 is in an unstressed state and is set to the maximum tension state. An arc-shaped pressure plate 406 is connected to the outer wall of the insert plate 403 by screws. The arc-shaped pressure plate 406 is located on the outer side of the movable door 401, and the two ends of the arc-shaped pressure plate 406 are fixedly connected to the ends of the two sets of insert plates 403 respectively.

[0033] Therefore, when the arc-shaped pressure plate 406 is pressed down, the insert plate 403 can be moved down synchronously. At this time, downward pressure is applied to the compression spring 405, and the compression spring 405 is compressed and deformed. After holding the arc-shaped pressure plate 406 and pressing down, the insert plate 403 can be moved out of the insertion slot 303, releasing the fixed state of the movable door 401. The movable door 401 can be pulled out directly to complete the disassembly. When the movable door 401 needs to be reinstalled, the arc-shaped pressure plate 406 is pressed down again to push the movable door 401 into the inner side of the sliding frame 301. Using the elastic reset function of the compression spring 405, the insert plate 403 is pushed into the insertion slot 303.

[0034] Example 3

[0035] Please see Figure 1-5A magnetic magnet 407 is screwed to one side of the movable door 401 near the inside of the sliding track 302. An iron sheet 306 is screwed to the inner wall of the sliding track 302 near the movable door 401. The magnetic magnet 407 and the iron sheet 306 attract and adhere to each other. When the movable door 401 is pushed into the inner side of the sliding frame 301, the mutual attraction between the magnetic magnet 407 and the iron sheet 306 causes the bottom surface of the movable door 401 to press tightly against the inner wall of the sliding frame 301, thus aiding in installation. A sealing gasket 408 is screwed to the inner wall of the movable door 401 near the roller 2. The sealing gasket 408 is made of rubber and has a good sealing effect. When the movable door 401 is pushed into the inner side of the sliding frame 301... The sealing gasket 408 fits against the outer wall of the roller 2, sealing the inside of the roller 2. The side of the sealing gasket 408 away from the movable door 401 is in close contact with the outer wall of the roller 2. Two sets of limiting grooves 304 are provided on the outer wall of the sliding frame 301. Insert rods 305 are inserted into the inside of each of the two sets of limiting grooves 304. The bottom end of the insert rod 305 extends into the inside of the movable door 401. The outer wall of the movable door 401 has a slot that matches the insert rod 305. When the top end of the insert rod 305 is held and moved outward, the re-fixing effect on the movable door 401 can be released. When the bottom end of the insert rod 305 is reinserted into the limiting groove 304, the installation effect of the movable door 401 can be further fixed, increasing the stability of the installation of the movable door 401.

[0036] Working principle: First, hold the top of the insertion rod 305 and move it outward until the bottom of the insertion rod 305 moves to the outside of the sliding frame 301, initially releasing the fixing work of the movable door 401. Then, press the top surface of the arc-shaped pressure plate 406 towards the outer wall of the roller 2.

[0037] Next, the arc-shaped pressure plate 406 moves downward, driving the insert plate 403 to move downward. At this time, the insert plate 403 applies a downward force to the telescopic rod 404 and the compression spring 405. The telescopic rod 404 is compressed and begins to shorten under pressure, and the compression spring 405 is compressed and deformed under pressure until the insert plate 403 moves into the interior of the movable slot 402. Then, the force on the arc-shaped pressure plate 406 is maintained, and the movable door 401 is pulled outward until the movable door 401 moves to the outside of the sliding frame 301.

[0038] Finally, the meat and marinade are placed inside the drum 2. The arc-shaped pressure plate 406 is pressed down, and the movable door 401 is aligned with the inside of the sliding frame 301 and pushed back. When the insert plate 403 moves to the position below the insertion slot 303, the elastic reset function of the compression spring 405 is used to push the insert plate 403 into the insertion slot 303, completing the fixing of the movable door 401. The vacuum system and drive system are turned on in sequence through the control panel, and the vacuum pump is started to pump air to the target pressure. The motor drives the drum 2 to run according to the program. During this process, forward and reverse rotation and pause can be automatically switched. After the set time is completed, it will stop automatically. After releasing the vacuum, the above disassembly of the movable door 401 is repeated to complete the removal of the meat. Finally, the work is completed.
