Following the dewatering stage in plastic recycling, particularly for film and PET, a Thermal Drying Machine plays a crucial role in achieving the low moisture levels required for high-quality recycled plastics.

How it Works:
This machine utilizes hot air to effectively dehydrate plastic materials. After dewatering, the material is conveyed into a long stainless steel tubing system where it comes into contact with hot air, similar to a hair dryer. This process significantly reduces moisture content.
Enhanced Drying with Cyclone Separation:
Many thermal dryers incorporate a cyclone separator. This component introduces cool air, further reducing residual moisture and effectively removing dust and fines from the material stream, resulting in cleaner, drier plastic.
Achieving Optimal Moisture Levels:
Typically installed after the dewatering machine, the thermal dryer is essential for bringing down moisture content to below 3%. For larger operations requiring ultra-low moisture levels, multiple thermal heaters can be used in sequence.
Specifications and Customization:
Thermal dryers come in various sizes and configurations to meet specific needs. For example, the RSJ800 model boasts a 5.5 KW blower power, 36 KW heating power, a 159mm diameter pipe made from durable type 304 stainless steel, and CE certification. Larger and more powerful models are available for higher throughput requirements.
