[0002] Vacuum freeze-drying technology is a new drying method that freezes water-containing materials into solids and uses the sublimation properties of water under low temperature and low pressure conditions to dehydrate the materials at low temperature to achieve drying. Since vacuum freeze-drying technology is carried out in a low temperature and low oxygen environment, most biological reactions are stagnant, and there is no liquid water in the treatment process. The water sublimates directly in a solid state, so that the original structure and shape of the material are protected to the greatest extent, and finally a high-quality dry product with both appearance and internal quality is obtained.

[0003] For example, a vacuum freeze-drying device with Chinese patent number CN216159475U, in which the heat in the working room is discharged from the first heat dissipation hole by starting the heat exhaust fan, and the refrigeration plate is started to cool the temperature in the working room. However, the energy consumption of the utility model is too high in actual use, which increases the cost during use. At the same time, there is a lack of a mechanism for cleaning the dustproof structure, which requires manual cleaning, increases the amount of manual labor during use, and is inconvenient for users. Therefore, a low-energy low-temperature vacuum freeze-drying device is proposed to solve the above problems. Utility Model Content

At the same time, fixed and movable installations are determined according to actual application methods. To ensure the compatibility of the equipment, the operating methods used are consistent with the parameters of marketed equipment. The description here is not admitted to be prior art because it is included in this section.

[0029] When implementing, follow these steps:

[0030] 1) Firstly, two semiconductor refrigerators 408 are started to cool down the installation frame 407, so as to reduce the mesh temperature on the installation frame 407;

[0031] 2) Then, the user can manually rotate the transmission wheel 403 and use the belt loop to make the two transmission wheels 403 drive the two screw rods 402 to rotate, and the transmission cleaning plate 404 moves up and down;
