[0003] Plastic particles are the main raw material for manufacturing plastic products. Plastic particles easily absorb moisture and form lumps. The quality of plastic products made with damp plastic particles will be significantly reduced, and it will cause certain damage to the injection molding machine. Therefore, before entering the injection molding machine, the plastic particles need to be dried through a drying process to remove the moisture contained in the plastic particles.

[0005] The device uses a motor to drive a bidirectional screw rod so that the gear drives the agitator to rotate, and the blower dries the agitator to achieve a full drying effect.

[0006] In the existing plastic pellet drying device used in plastic production, the plastic pellets fail to be turned over and stirred during the drying process, so they stick together and cannot be fully dried. In addition, the debris and impurities contained in the plastic pellets cannot be screened out, which reduces the quality of the plastic pellets. At the same time, the plastic pellets are only dried by high-temperature drying, and the water vapor and water in the plastic pellets are lost slowly, which affects the heat dissipation efficiency of the plastic pellets.
