The plastic hopper dryer is a device used for drying plastic particles. It is usually used in conjunction with plastic processing equipment such as injection molding machines and extruders. By heating and circulating air, the plastic hopper dryer can remove moisture from plastic particles and improve the processing performance and product quality of plastics.

A plastic dryer is a device used to remove moisture from plastic raw materials. During plastic processing, excessive moisture can affect the quality of plastic products, such as causing bubbles and surface defects. It uses methods like heating and ventilation to evaporate the water in plastic pellets, ensuring that the plastic can have good performance in subsequent molding processes, such as injection molding and extrusion.
