[0025] As a technical optimization solution of the utility model, by setting the rolling groove 16 and the roller group 17, the sliding friction between the moving block 6 and the moving groove 5 can be converted into rolling friction, so that it is convenient for the staff to take out or place the supporting plate 7, thereby improving the smoothness of the operation.

When the leveling strip 15 contacts the wet materials piled together, the wet materials higher than the leveling strip 15 can be driven to rotate, and the centrifugal force during rotation is used to deviate the wet materials outward, so as to fill the redundant gaps between the materials, thereby avoiding overlapping or accumulation. Then, the remaining wet materials can be placed in other drying plates 9 according to the specified volume and flattened. After the wet materials are placed, the bearing plate 7 can be pushed to return to its position, and then the sealing door 3 can be closed to seal the drying chamber 2, and then the vacuum pump 4 can be started to extract the air in the drying chamber 2 to make it in a vacuum state, and then the dryer body 1 can be started to perform low-temperature drying operations.
