The output end of the motor 12 extends through to the bottom of the inner wall of the tank body 1 and is fixedly connected to a transmission rod 13. The top of the transmission rod 13 passes through the small drying tray 2 and the large drying tray 3 and is movably connected to the middle of the top of the tank body 1 through a bearing. A guide rake blade 14 is fixedly connected to the surface of the transmission rod 13 and to the top of the small drying tray 2 and the large drying tray 3.

[0023] refer to Figure 2 The front side of the tank body 1 is provided with inspection holes 15, and the number of inspection holes 15 is three.

[0024] As a technical optimization of this utility model, by setting the inspection hole 15, the condition inside the tank 1 can be observed during the drying process, which is convenient for the user.

[0025] refer to Figure 2 A cover plate 16 is movably connected to the front side of the inspection hole 15 via a pin.

[0026] As a technical optimization of this utility model, by setting a cover plate 16, the inspection hole 15 can be covered to prevent foreign objects from entering the tank 1 through the inspection hole 15.

[0035] The working principle and usage process of this utility model are as follows: In use, hot air is first injected into the upper-positioned small drying tray 2 and large drying tray 3 through the hot air pipe 5 and the conveying pipe 6, heating the upper-positioned small drying tray 2 and large drying tray 3. Simultaneously, cold water is injected into the lower-positioned small drying tray 2 and large drying tray 3 through the cold water pipe 7 and the conveying pipe 6, cooling the lower-positioned small drying tray 2 and large drying tray 3. Then, raw materials are injected into the tank 1 through the feed pipe 9, causing the raw materials to fall onto the top-positioned small drying tray 2. At the same time, the motor 12 is started, and the output end of the motor 12 drives the transmission rod 13 to rotate. The transmission rod 13 drives the guide rake 14 to rotate, and the guide rake 14 continuously pushes the raw material on the small drying tray 2 towards the edge, so that the raw material on the small drying tray 2 falls onto the large drying tray 3. At the same time, the guide rake 14 continuously pushes the raw material on the large drying tray 3 towards the inner edge, so that the raw material on the large drying tray 3 falls onto the lower small drying tray 2. At this time, the raw material can be dried by injecting hot air into the small drying tray 2 and the large drying tray 3, and then cooled by injecting cold water into the small drying tray 2 and the large drying tray 3. Finally, the dried and cooled raw material is discharged through the discharge pipe 10, thus drying the raw material.
