[0035] Specifically, the box body 1 is used to protect and connect its internal parts, the box door 2 is used to connect the vibration and collection components, the outer plate 3 and the inner plate 4 cooperate to ensure that the box door 2 remains stationary when the vibration component is working and will not move around to affect the sealing of the device. The connecting plate 5 is used to connect part of its vibration components. One end of the fixing rod 6 is connected to the box door 2, and the other end is connected to the motor 7 to ensure that during the vibration process, the motor 7, like the box door 2, will not move around. The motor 7 is an important component for driving the vibration component, which drives the turntable 8 to rotate continuously. When the turntable 8 rotates, it drives the push rod 9 to move back and forth continuously, and the push rod 9 pushes the connecting plate 5 to move back and forth continuously. , to achieve vibration, the limit block 10 is used to limit the movement direction of the outer plate 3, thereby limiting the entire vibration component, the electric push rod 11 is used to facilitate the opening of the box door 2, the box door 2 brings out the internal components, thereby facilitating operation, the base 12 is used to raise the device to prevent the box body 1 from being placed directly on the ground to avoid damage due to moisture, the slide bar 13 is used to limit the movement direction of the box door 2 to ensure that the box door 2 can only move forward and backward to avoid shaking, the vacuum device 14 is used to extract the air in the box body 1 and realize the vaporization of the moisture contained in the food, and the freezing device 15 is used to lower the temperature in the box body 1 and freeze the moisture in the food.

[0036] Reference Figure 2 , Figure 5 , Figure 8 The collecting assembly includes a motor 16 and a collector 23. The rear side of the motor 16 is fixedly connected to the front side of the box door 2. The output end of the motor 16 is fixedly connected to an inner rod 17. The rear side of the inner rod 17 is slidably connected to an outer rod 18. The left and right sides of the outer rod 18 are fixedly connected to main boards 19. The front sides of the two main boards 19 away from the outer rod 18 are rotatably connected to connecting rods 20. A plurality of sub-plates 21 are rotatably connected between the two connecting rods 20. The rear side of the sub-plate 21 is fixedly connected to a rotating rod 22. The front side of the collector 23 is fixedly connected to the rear side of the left part of the box door 2. A collecting port 24 is provided on the front side of the bottom of the collector 23. The front end of the inner rod 17 is rotatably connected to the rear side of the box door 2. The rear end of the outer rod 18 is rotatably connected to the front side of the connecting plate 5. The rear end of the rotating rod 22 is rotatably connected to the front side of the connecting plate 5. The inside of the collector 23 is slidably connected to the left side of the box body 1, and the bottom of the collector 23 is slidably connected to the inside of the base 12.

[0037] Specifically, the motor 16 is used to facilitate the tilting of the sub-plate 21 to collect the food above into the collector 23. The inner rod 17 slides inside the outer rod 18, and the two cooperate with each other to prevent the box door 2 from shaking when the vibration component is working, affecting the sealing. The main board 19 is the top platform for placing food. The connecting rod 20 connects the top main board 19 and the multiple sub-plates 21 below to achieve synchronous movement of the main board 19 and the sub-plates 21, so that the food can slide into the collector 23 at the same time and in the same direction. The rotating rod 22 rotates in the connecting plate 5 to ensure the stability of the sub-plate 21 and limit the movement direction of the sub-plate 21. The collector 23 is used to collect food collectively, and the collection port 24 is used to facilitate the removal of food dropped into the collector 23.

[0038] Working principle: when it is necessary to use the device, firstly, the electric push rod 11 is controlled by an external power supply to drive the box door 2 to be opened, and the vibration component and the collection component are pulled out together through the cooperation of the outer plate 3 and the inner plate 4, and then the food to be processed is randomly placed on the main plate 19 and the auxiliary plate 21. After placing them, the electric push rod 11 is controlled to close the box door 2 to keep the box body 1 sealed. At this time, the freezing device 15 and the motor 7 are controlled to work at the same time. The freezing device 15 will slowly freeze the moisture in the food, and the motor 7 drives the turntable 8 to rotate, and the turntable 8 drives the push rod 9 to push the connecting plate 5 to move back and forth continuously to achieve vibration, so as to evenly spread the food accumulated on the main plate 19 and the auxiliary plate 21 so that it can be frozen evenly. When the moisture in the food is completely frozen, the vacuum device 14 is started to extract the air in the box body 1, and the ice vapor in the food is extracted together to achieve drying. The vibration component is combined to improve the efficiency of this process and ensure uniform drying. When drying is completed, the freezing equipment 15, the vacuum equipment 14 and the motor 1 7 are turned off to allow air to slowly enter the box body 1. At this time, the electric push rod 11 is controlled to open the box door 2. When the motor 2 16 is controlled to rotate, the inner rod 17 drives the outer rod 18 to rotate. At this time, the main board 19 will tilt. Through the pulling of the connecting rod 20, the sub-board 21 will tilt synchronously to slide the food into the collector 23. After collection, the motor 2 16 is controlled to return the main board 19 to the normal position. When the electric push rod 11 is controlled to close the box door 2, the box door 2 drives the collector 23 to move backward together. There is a baffle on the left side of the box body 1 that slides in the collector 23. When the collector 23 moves, it will block the food and finally fall from the collection port 24. The staff only needs to place a box under the collection port 24 to achieve rapid collection, which effectively improves work efficiency.
