Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] See appendix Figure 1-4As shown, a low-temperature dehydration and preservation processing device for vegetables includes a preservation box 1. A multi-layer vegetable dehydration device 2 is installed inside the preservation box 1. A cleaning device 3 is installed on one side of the preservation box 1. The multi-layer vegetable dehydration device 2 rotates on a pivot 4 located in the middle of the preservation box 1. A short rod 5 is radially and vertically fixed to the pivot 4. Air outlets 6 are provided at the end, bottom, and sides of the short rod 5. A vegetable placement net 7 and an inclined plate 8 are laid on the lower part of the short rod 5. Mesh grooves 9 are symmetrically fixed at both ends of the vegetable placement net 7. The inclined plate 8 is located between the vegetable placement nets 7. Inclined plates 8 are symmetrically fixed to the inner wall of one side of the preservation box 1. A rotary motor 10 is installed on the upper part of the preservation box 1, and a rotating shaft 4 is connected to the lower part of the rotary motor 10. A round hole is opened on the upper part of the preservation box 1 corresponding to the bottom position of the rotary motor 10. A round groove is opened on the lower inner wall of the preservation box 1 corresponding to the bottom position of the rotating shaft 4. A partition 11 passes through the round groove at the bottom of the rotating shaft 4. Drainage holes 12 are symmetrically arranged on the upper edge of the partition 11. The partition 11 is fixed to the lower half of the interior of the preservation box 1. The bottom of the rotating shaft 4 is connected to the partition 11 through the round groove. A hot air blower 13 is connected to the hot air blower 13. Two partitions 14 are installed on both sides of the hot air blower 13. A water storage tank 15 is symmetrically arranged on the side of the partition 14 away from the hot air blower 13. The water storage tank 15 is located below the drain hole 12. A hole is opened inside the rotating shaft 4 for air transmission from the hot air blower 13. An air outlet 16 is opened on the part of the rotating shaft 4 between the vegetable placement net 7 and the partition 11. A rectangular block 17 slides in the middle of the side of the preservation box 1 away from the inclined plate 8. A handle 18 is fixed to the outside of the rectangular block 17, and a [missing information - likely a component or part] is fixedly connected to the lower inner side of the rectangular block 17. The vegetable placement net 7 and the preservation box 1 have rectangular openings at the sliding positions of the rectangular blocks 17. A vacuum pump 19 is installed at the upper part of one end of the preservation box 1, and a condenser pipe 20 is installed at the lower part of the vacuum pump 19. A fan 21 is installed below the condenser pipe 20. A second drain hole 22 is symmetrically opened at one end of the preservation box 1 corresponding to the inner wall of the water storage tank 15. A water storage tank 23 is set below the end of the preservation box 1 located at the second drain hole 22. The vacuum pump 19 is a BECKER brand VT4.25-4.40 model, which has low energy consumption and good performance.

[0020] Specifically, the rectangular block 17 and the vegetable placement net 7 are completely pulled out along the mesh groove 9 by the handle 18. The vegetables are placed on the multi-layer vegetable placement net 7 in advance, and then the cabinet door and box door 28 are closed tightly. The air extracted by the vacuum pump 19 is condensed into water by the condenser pipe 20 and flows to the water storage tanks 15 at both ends for storage. It is discharged into the water storage tank 23 through the second drain hole 22 for collection. The hot air in the equipment enters through the fan 21, is heated by the hot air blower 13, and is sent into the rotating shaft 4 and blown out in sequence from the second air outlet 16 and the first air outlet 6. At the same time, the rotating motor 10 is started, and the rotating shaft 4 drives the multiple sets of short rods 5 on it to rotate, forming a faster airflow and accelerating the drying of vegetables. The moisture in the equipment falls onto the partition 11 through the vegetable placement net 7, is discharged into the water storage tank 15 below through the first drain hole 12 at both ends, and is finally discharged into the water storage tank 23 through the second drain hole 22 for collection. The vegetable placement net 7 filters the residual moisture with fine gaps to improve the drying efficiency.

An electric telescopic rod 25 is vertically fixed to the upper part of the electric telescopic rod 24 along the long side of the rectangular block 17. A push plate 26 is fixed to the front end of the electric telescopic rod 25, and a brush 27 is installed at the lower part of the push plate 26. The cleaning height can be adjusted by activating the electric telescopic rod 24. When the handle 18 completely pulls out the rectangular block 17 and the vegetable placement net 7 along the mesh groove 9, after the dehydrated and preserved vegetables are collected, the electric telescopic rod 25 is activated, and the reciprocating motion of the brush 27 is used to clean the vegetable placement net 7 in layers.

[0022] In addition, a door 28 is installed at the end of the preservation box 1 away from the vacuum pump 19, and a temperature and humidity sensor display screen 29 is installed on the door 28. During operation, the temperature, humidity, working time and other parameters of the equipment can be controlled through the temperature and humidity sensor display screen 29, which can greatly improve work efficiency and regulate the preservation environment of dehydrated vegetables. The entire preservation box 1 and the door 28 have a good sealing effect, and the equipment can be in a safe working environment.

[0023] The working principle of this utility model is as follows: The preservation box 1, the multi-layer vegetable dehydration device 2, and the cleaning device 3 are assembled together. Vegetables are placed on the multi-layer vegetable placement net 7 beforehand, and then the cabinet door and box door 28 are closed. The air extracted by the vacuum pump 19 is condensed into water through the condenser pipe 20 and flows to the water storage tanks 15 at both ends for storage. The water is discharged into the water storage tank 23 through the second drain hole 22 for collection. The hot air in the equipment enters through the fan 21, is heated by the hot air blower 13, and is sent into the rotating shaft 4 and blown out in sequence from the second air outlet 16 and the first air outlet 6. At the same time, the rotating motor 10 is started, and the rotating shaft 4 drives the multiple sets of short rods 5 on it to rotate, forming a faster airflow and accelerating the drying of vegetables. The moisture in the equipment falls onto the partition 11 through the vegetable placement net 7. The water flows through the drain holes 12 at both ends into the water storage tank 15 below, and finally through the drain hole 22 into the water storage tank 23 for collection. The vegetable placement net 7 filters residual moisture with fine gaps, improving drying efficiency. The electric telescopic rod 24 is activated to adjust the cleaning height. When the handle 18 completely pulls the rectangular block 17 and the vegetable placement net 7 along the mesh groove 9, the dehydrated and preserved vegetables are collected. Then, the electric telescopic rod 25 is activated, and the reciprocating motion of the brush 27 cleans the vegetable placement net 7 layer by layer. During operation, the temperature, humidity, and working time parameters of the equipment can be controlled through the temperature and humidity detector display screen 29, which can greatly improve work efficiency and regulate the preservation environment of the dehydrated vegetables. In this invention, the efficient cooperation of the vegetable placement net 7, the air outlet, and the rotating shaft 4 achieves thorough drying of vegetables and easy drainage of accumulated moisture. The cleaning device 3 in this invention efficiently cleans the vegetable placement net 7, which has a high utilization rate, ensuring the sustainable use of the equipment.
