[0002] Food preservation is closely related to human life. Food preservation technology has always aimed to maintain the original quality of food as much as possible and continuously seeks more efficient, more economical, and safer new methods.

[0036] The drying mechanism includes a drying tank 704 arranged on the cover cylinder 701. A drying box 49 is fitted on the drying tank 704. Desiccant is prepared inside the drying box 49, and holes are opened at the bottom of the drying box 49. A staggering seat 50 is slidably fitted on the cover cylinder 701. One end of the staggering seat 50 is provided with a fitting part. The fitting part cooperates with the adjusting part 21 for moving and adjusting. The mounting mechanism includes a magnetic snap 703 arranged between the cover cylinder 701 and the bottom cylinder 702. The cover cylinder 701 is rotatably arranged on the bottom cylinder 702 and is magnetically fixed by the magnetic snap 703.

[0037] The working principle is as follows: The magnetic field generator 2 generates a magnetic field to form a magnetic field region. Under the simultaneous action of a low-temperature temperature field and a high-frequency electromagnetic field, food is preserved. The carriage 3 can be pulled out of the interior of the cabinet 1. By opening the cover cylinder 701, food can be placed in the bottom cylinder 702. The food is located on the support plate 34. The cover cylinder 701 and the bottom cylinder 702 are closed. In this state, humidification preservation and drying dehumidification treatment can be carried out on the food. That is, humidity sensors are arranged inside the placement cylinder 7. According to the feedback signals of the humidity sensors, the humidity and drying inside each placement cylinder 7 can be adjusted individually.

[0038] Specifically, when the first motor 19 works, the lead screw 6 rotates to move the control slider 8, that is, to move below each placement cylinder 7, and vibration dehumidification can be carried out on the food, that is, the excess water attached to the food is removed through vibration. Specifically, the position cylinder 10 controls the movement of the mounting plate 11, so that the push rod 16 contacts and pushes the fixed push rod 39. The fixed push rod 39 moves, so that the fixed shaft 38 is disengaged from the fixed shaft 38, that is, the fixed state of the sliding shaft 35 is released. At the same time, the contact seat 15 contacts the bottom of the sliding shaft 35. The position cylinder 10 controls the mounting plate 11 to move repeatedly, and the contact seat 15 pushes the sliding shaft 35, that is, to make the sliding shaft 35 produce a vibration effect. The push rod 16 contacts the parallel area above the fixed push rod 39. During vibration, the fixed shaft 38 is always kept from moving.

[0039] Furthermore, when the support plate 34 vibrates, the excess water on the food can be removed through vibration. The water is collected into the circulation box 32 through the support plate 34. The docking cylinder 12 controls the docking interface 13 to cooperate and fix with the docking valve 33 to transfer the water to the collection box 9. When removing water through vibration, the height of the drive motor 24 can be controlled by the drive cylinder 23, so that the two drive cylinders 25 are respectively engaged with the second rotating shaft 40 and the first rotating shaft 30. Through the clamping cylinder 26 for clamping and fixing, the first rotating shaft 30 and the second rotating shaft 40 can be driven to rotate, and then the winding and unwinding reel 46 and the winding and unwinding shaft 44 can be rotated to control the movement of the winding and unwinding carriage 43, that is, the winding and unwinding carriage 43 pulls the winding and unwinding layer 45 to move. The winding and unwinding layer 45 covers above the food. By the operation of the air box 27, that is, transmitting gas, the gas is transmitted from the winding and unwinding reel 46 to the expansion airbag 47 through the air pipe, so that the expansion airbag 47 expands. The adsorption layer 48 on the lower surface of the expansion airbag 47 can contact the food and adsorb the water on the food, that is, attach and remove the water, and during vibration, the food will not jump significantly.

[0040] Furthermore, drying adjustment can also be performed. When the humidity inside the placement tube 7 is too high, the motor 2 17 can be operated, the screw 2 18 can be rotated, that is, the slide 22 can be moved, and the electric cylinder 20 can be adjusted to control the height of the adjustment part 21 so that the adjustment part 21 is located in the adjustment position, that is, the adjustment part 21 cooperates with the staggered seat 50, which can drive the staggered seat 50 to move, that is, the staggered seat 50 is gradually staggered with the bottom of the drying box 49, that is, the exposure area of ​​the desiccant is adjusted to adjust the humidity. Each food has different requirements for humidity and dryness. Therefore, this embodiment can perform separate humidity and dryness adjustment for each food in the placement tube 7, and combine the simultaneous action of the high-frequency electromagnetic field to achieve food preservation.
