[0015] (III) Beneficial effects
[0016] The dehumidifying dryer for PETG plastic particles has a simple structure and is easy to use. The hard tube and the guide mechanism are arranged, and the hard tube is driven to rotate by a driving motor. The hard stirring tube stirs the plastic particles in the barrel, which helps to achieve rapid and uniform mixing of the plastic particles and improves production efficiency. The dry gas enters the hard tube through a rotary joint and is ejected through an air jet port to uniformly dehumidify and dry the plastic particles, ensuring that the plastic particles can be fully dried in the entire processing process and improving the quality of the plastic particles. Due to the oscillation of the hard stirring tube and the rapid flow of the plastic particles, the plastic particles can be effectively prevented from being blocked in the barrel, thereby maintaining the continuity and stability of production.
