The invention discloses a drying device for traditional Chinese medicine medicinal materials. The drying device comprises a drying cabinet, a discharging opening and a feeding opening, wherein the feeding opening is formed in the drying cabinet; the discharging opening is formed in the bottom of the drying cabinet; an exhaust fan is mounted at the upper part of the side wall of the drying cabinet;a blower is mounted at the lower part of the side wall of the drying cabinet, and is connected with an electric heating cabinet through a wind inlet pipeline; a conveyor belt is arranged in the drying cabinet, and is driven by roller wheels; and a plurality of arc-shaped baffles are arranged on the conveyor belt. According to the drying device for the traditional Chinese medicine medicinal materials disclosed by the invention, the conveyor belt is arranged in the drying cabinet; the arc-shaped baffles which are used for pushing the medicinal materials to form circulation are arranged on the conveyor belt, so that the situation that the medicinal materials are accumulated at one place, and vapor cannot be quickly dispersed is avoided, and the problems that in the prior art, the heating isnot uniform, and the vapor cannot be dispersed are effectively solved; and the drying device adopts an upper fan and a lower fan to respectively control wind transmitting and wind inletting to form asmooth flow channel, the heat dissipation of the vapor is accelerated, and the heat dissipation efficiency is improved.
