Through the cooperation of a feed hopper, a hopper cover, a collar, an activated carbon filter, a driving assembly, a rotating shaft, a stirring member, a connecting column, a triangular plate and a drying assembly, not only can the granular polyvinyl chloride be evenly dried, but also the toxic substances generated by the granular polyvinyl chloride in the heating and drying process can be purified and then discharged to the outside, avoiding affecting the surrounding air quality and ensuring the health of surrounding employees.
