Thermal Dryer for Plastic Recycling
Achieve the lowest possible moisture levels with our high-efficiency thermal dryer system. This is the crucial final step in your washing line to produce premium-quality plastic flakes ready for pelletizing.
Achieve Premium Quality & Efficiency
Our thermal dryer is engineered to be the final gatekeeper of quality in your washing line, ensuring your material meets the strictest standards for pelletizing.
Ultra-Low Moisture Content
The crucial final drying step after mechanical dewatering. Our system uses controlled hot air to reliably reduce final moisture levels to below 3%, and often as low as 1%.
Enhanced Product Quality
Properly dried flakes prevent issues like foaming and voids during pelletizing, resulting in higher-quality, more valuable final plastic pellets that can be sold for a premium.
Dust & Fines Removal
The integrated cyclone separator acts as a final cleaning stage, efficiently removing residual dust and fine particles from the material stream for a cleaner, purer product.
How Thermal Drying Works
Blower Transport
Partially dried flakes from the dewatering machine are vacuumed by a transport blower into the system.
Hot Air Mixing
The flakes are mixed with a stream of hot air and travel through an extended set of stainless steel pipes.
Dehydration
As the material spirals through the transport tunnel, the hot air efficiently evaporates the remaining moisture.
Cyclone Separation
The dried flakes enter a cyclone separator, where they are separated from the moist air, dust, and fines before discharge.
Key Applications in Plastic Washing Lines
PET Flake Drying
An essential final step in PET bottle washing lines to achieve the low moisture levels required for producing high-quality rPET pellets for food-grade and other advanced applications.
Plastic Film Drying
Effectively dries washed PE/PP films after the squeezer-dryer stage, ensuring they are ready for the pelletizing extruder without causing production issues.

Frequently Asked Questions
Why is this necessary after a centrifugal dewatering machine?
A centrifugal dewatering machine is excellent for removing the bulk of surface water mechanically, typically down to 2-3% moisture. However, for high-quality pelletizing, moisture must be even lower (ideally <1%). The thermal dryer uses heat to evaporate this remaining, stubborn moisture that mechanical force cannot remove.
What is the final moisture level I can expect?
With a properly configured system, you can consistently achieve a final moisture content of less than 3%, with many of our clients reaching below 1%. For the absolute lowest moisture levels, some high-capacity plants opt to install two or three thermal heating units in sequence.
Can this system be customized for higher capacities?
Yes. The RTMSJ800 is our standard model, but we can design and manufacture larger, more powerful systems with increased blower and heating power to match the specific throughput of your washing line. Please contact our technical team to discuss your requirements.
