[0041] The refrigeration device 4 is used to freeze the moisture in the material in the rotating silo structure; the cold air generated by the refrigeration device 4 flows through the gas flow channel opened in the middle of the rotating cylinder 17 and is heat exchanged with the rotating silo structure. When the cold air flows, the rotating cylinder 17 is driven to rotate through the blades 9, and the blades 9 are axially connected in the gas flow channel;

[0042] The vacuum sublimation device 3 is used for vacuum sublimation of ice crystals in the material in the rotating silo structure. The air inlet end of the vacuum sublimation device 3 is connected to a plurality of rotating silo structures.
