The activated carbon provided in the drying box 6 can absorb moisture in the air and dry the air. The dried air is introduced into the second duct 7 again, contacts with the heating tube 14, and then enters the drying box 1 again to contact with the bamboo shoots to dry the bamboo shoots, forming a cycle drying to improve the utilization rate of heat.
