The invention discloses a dryer for chitin processing. The dryer comprises a bottom plate, a box body is arranged on the left side of the top of the bottom plate, heater bands are fixedly connected to the two sides of the inner wall of the box body correspondingly, slide rods are fixedly connected to the two sides of the bottom of the box body correspondingly, a sliding chute is formed in the left side of the top of the bottom plate, and the slide rods are connected to the sliding chute in a sliding mode; and a connecting block is fixedly connected to the right side of the box body, a fixed plate is fixedly connected to the right side of the top of the bottom plate, a movable plate is movably connected to the top of the front surface of the fixed plate, and a toothed plate is fixedly connected to the left side of the movable plate. According to the dryer for chitin processing, by arranging the bottom plate, the box body, the heater bands, the slide rods, the sliding chute, the connecting block, the fixed plate, the movable plate, the toothed plate, a fixed block, an electric telescopic rod, a supporting plate, a gear and a connecting rod to be used cooperatively, the high-efficiency drying effect is achieved, and the problems that an existing chitin dryer is low in drying efficiency, therefore the drying cost of chitin is increased, and the practicability of the chitin dryer is reduced are solved.
