[0074] The sliced traditional Chinese medicine raw materials are added into the first drying cylinder 1 through the conical feeding hopper 4 and the feeding funnel 3 for preliminary drying. By controlling the opening and closing of the switch valve 14 on the discharge pipe 12, the preliminarily dried traditional Chinese medicine raw materials can fall onto the first conveyor 13 through the discharge pipe 12 at the lower end of the first drying cylinder 1. Start the first conveyor 13, and the first conveyor 13 can work to pour the preliminarily dried traditional Chinese medicine raw materials into the second drying cylinder 6 through the feeding funnel 3 at the upper end of the second drying cylinder 6 and the feeding pipeline 5 for secondary drying.
