[0002] Plastic granules are plastic particles, which mainly exist in the form of semi-finished plastics, which are convenient for people to store, transport and process into shapes. Plastic granules generally refer to granular plastics, which are often used in daily life and have a wide range of applications. Plastic granules need to be dried during the processing process to facilitate storage and improve product quality.

[0003] A Chinese patent application with application number 202320384898.1 discloses a drying device for producing plastic particles, including a mounting frame, a drying barrel hinged on the left side of the top of the mounting frame, a connecting frame installed on the right end of the top of the mounting frame, a driving motor installed on the front of the connecting frame, and a double-threaded rod driven by the driving motor is connected. The back of the double-threaded rod passes through the connecting frame and extends to the outside of the connecting frame. A movable block is threadedly sleeved on the outer surface of the double-threaded rod, which can discharge the plastic particles inside the drying barrel to avoid residual plastic particles inside.

[0004] However, the particles are moved by the drying barrel and dried by the wind blown by the fan. The rotation speed of the drying barrel needs to be kept slow and stable to maintain the fit between the plastic particles and the drying barrel. After the drying is completed, it is found that there is a problem of adhesion between some particles. For this reason, we propose a drying device for plastic particle production.

The first air induction plate 11, the second air induction plate 12 and the third air induction plate 13 simultaneously play the role of blocking the plastic granules from leaving the roller through the air induction plate, so that the drying is uniform and the possibility of adhesion is reduced.
