This kind of drying device for plastic processing is provided with a sliding material track, the lower end of which is connected to a air supply block. The air supply block sends the hot air generated by the cooperation of the air pump and the heating device into the sliding material track, heats and dries the plastic particles sliding on the sliding material track, and forms an airflow from bottom to top in the sliding material track, which slows down the sliding of the plastic particles and prolongs their stay time in the sliding material track, ensuring the sufficient drying of the plastic.

[0004] However, when the plastic particles are heated and moved in the hot air, they will come into contact with the drying equipment, pipes or other surfaces, causing friction and generating static electricity, which will adhere to the drying equipment and pipes, making it inconvenient to quickly dry and collect the plastic particles.
