The invention discloses an industrial dryer. The industrial dryer comprises an electric heating fan; an air outlet of the electric heating fan is provided with a trumpet-shaped diffuser; the periphery of the diffuser is provided with a bracket; the top of the bracket is provided with a rotary table which is driven by a motor; a drying chamber is arranged on the rotary table and used for containing to-be-dried clothes; the bottom surface of the drying chamber is hollowed out and communicates with the interior of the diffuser; the top of the drying chamber is provided with a cover body; and the cover body is full of heat dissipation holes. The overall industrial dryer is of a tower type structure and is small in occupied area, the rotary table drives the drying chamber to rotate, quick flowing of heat air among the clothes is facilitated, and accordingly water in the clothes is quickly taken away; and the cloth drying speed of the dryer is increased, and thus the drying efficiency of the industrial dryer is effectively improved.
