Drying device for plastic particle processing

The utility model belongs to the technical field of plastic particle processing, and particularly relates to a drying device for plastic particle processing, which comprises a barrel body and an air outlet mechanism, the air outlet mechanism comprises a heating barrel fixedly connected to the back of the top of the barrel body through bolts, an air pump is fixedly assembled at the top of the heating barrel, and an air outlet is formed in the top of the air pump. The back face of the air pump communicates with an inner cavity of the heating cylinder through an air inlet pipe, and the front face of the air pump communicates with an exhaust pipe. Hot air is sequentially communicated to an air inlet pipe, an exhaust pipe, a first exhaust hole, a hollow cylinder, a stirring rod and a second exhaust hole by utilizing an air pump, so that the hot air and the plastic particles are fully contacted by utilizing the second exhaust hole in the surface of the stirring rod while the plastic particles are stirred by the sti
