[0002] Plastic pellets are a type of granular plastic material, usually used as semi-finished raw materials for the production of plastic products, and are made through processes such as melting, extrusion, and granulation. These pellets are easy to store, transport, and process, and are an indispensable raw material in the production of plastic products. Plastic pellets can be divided into many types, including general-purpose plastics, engineering plastics, thermosetting plastics, and special plastics such as functional polymer plastics.

[0003] The utility model with patent number CN215703171U discloses a highly efficient drying device for plastic particles, including a box body, a partition is fixedly connected to the top of the box body, a drying box is fixedly connected to the bottom of the partition, a motor is fixedly installed at the top middle end of the drying box, and a stirring shaft is fixedly connected to the output end of the motor. The utility model transports the material from the leakage plate to the inside of the drying box, starts the motor through the PLC controller, and then drives the stirring shaft to stir and rotate the material. After the heating plate inside the heating tank is heated, the air is transported to the heating box through the air supply pipe, which solves the problem that the existing plastic particles need to be dried after production.

[0004] During the production of plastic particles, a large amount of water will adhere to the surface of the plastic particles, and drying equipment is needed to dry the plastic particles. Although the device in the above patent improves the drying efficiency, the high temperature and stirring can easily cause the plastic particles to soften and deform, thereby reducing the yield rate of plastic particle production.
