[0002] In the production and processing of plastic materials, plastic particles contain a lot of water, and the plastic particles of the raw materials need to be dried. The drying device used in the production and processing of plastic particles is a device used to remove moisture from plastic particles. This type of equipment is very common in the plastic processing industry because plastics need to maintain a certain degree of dryness during the production process to ensure the quality of the finished product and production efficiency.

[0003] However, most of the drying devices used in the production and processing of plastic particles currently have the following problems:

[0004] 1. The existing drying devices for the production and processing of plastic particles, when drying the produced materials, mostly dry the moisture on the surface of the materials by heating the air. However, when processing, a large amount of materials are piled up together, which easily leads to the materials at the bottom being unable to be dried by the wind, affecting the efficiency and uniformity of the material drying process.

[0005] 2. In the existing drying devices for the production and processing of plastic particles, the drying warm air blown out is mostly in a fixed state during drying, resulting in a limited wind force range for conveying, poor subsequent drying effect, and easily causing some materials to fail to be dried by the wind, affecting the drying effect and making it inconvenient to carry out uniform wind conveying and drying.

[0006] Therefore, we have made improvements to this and proposed a drying device for the production and processing of plastic particles. Utility Model Content
