The first inner plate 14 and the second inner plate 19 are both installed with a mounting body 15, and a wind tube 20 is horizontally penetrated between the first inner plate 14 and the second inner plate 19. The drying structure is installed on the mounting body 15 by bolts. Wind deflectors 21 are distributed on the surface of the wind tube 20, and the wind deflectors 21 are arranged corresponding to the drying structure. A through hole 18 is opened on the surface of the connecting body 16, and the through hole 18 connects the inner cavity of the inner rotating barrel 17 with the inner cavity of the left mounting body 7, and the inner cavities of the two groups of inner rotating barrels 17 are connected. The driving structure drives the rotating drum 9 to rotate, and the drying structure rotates with the rotating drum 9.

[0032] In this embodiment, the specific working principle is as follows: the user pours the drug raw materials into the inner drum 17, and then drives the drum 9 to rotate through the driving structure, and uses the hot air component to heat the drum 9, thereby achieving the drying efficiency of the drugs in the inner drum 17. Secondly, the wind cylinder 20 will not rotate with the drum 9. Therefore, in the drum 9, the wind direction sometimes blows against the inner wall of the drum 9, and then blows toward other surfaces of the inner drum 17, thereby increasing the contact surface and improving the drying efficiency.
