Spiral shoveling plate roller dryer

The utility model discloses a spiral shoveling plate roller dryer, which has the main design concept that the spiral shoveling plate roller dryer consists of a spiral shoveling plate, a roller, a front chamber, a hot air inlet, a material inlet, a rear chamber, a hot air outlet and a material outlet, the material inlet and the hot air inlet are positioned at the front end of the roller and penetrate through the front chamber; the material outlet and the hot air outlet are positioned at the rear end of the roller and penetrate through the rear chamber; and the plurality of spiral shoveling plates are respectively and fixedly arranged on the inner wall of the roller along the axial direction. The material drying efficiency is improved, drying and stirring are uniform, the gravity effect and the inherent pushing force of the spiral structure can be fully utilized, materials are pushed to move along the axis, efficiency is improved, energy is saved, emission is reduced, and therefore the operation cost of the rol
