This stirs and dries the plastic granules inside the drying tank 2, thus achieving uniform drying. The air in the drying tank 2 is discharged into the heat preservation box 1 through the air outlet groove, which raises the temperature in the heat preservation box 1 and heats and insulates the surface of the drying tank 2, thereby maintaining a uniform temperature inside the drying tank 2. After the plastic granules are dried, open the valve, and the plastic granules are discharged from the discharge pipe 5.
