[0002] During the production process, plastic granules are extruded into shape by an extruder and then cooled by water. After cooling, the formed plastic needs to be cut into granules. Since the plastic is cut directly after cooling, there will be residual moisture on the surface of the plastic granules.

[0003] When dehydrating plastic particles, a vertical plastic particle dehydrator is usually used. In the existing vertical plastic particle dehydrator, the power drive unit is often arranged on the top side of the dehydrator body, which has certain operational difficulties when maintaining and repairing the power drive unit. At the same time, during production and installation, the motor of the drive unit needs to be lifted to the installation position on the top side of the dehydrator body with the help of a sling. This process is relatively time-consuming and labor-intensive, and the installation is difficult. Therefore, in view of this, the existing structure and defects are studied and improved, and a plastic particle dehydrator is provided, in order to achieve a more practical purpose.
