Thermal Dryer for Plastic Recycling
Our thermal dryer is an outstanding method for extracting moisture through dehydration. Specifically engineered for our plastic film and PET washing lines, this continuous drying apparatus is strategically positioned after the dewatering machine. It serves as a crucial final step in reducing moisture levels to below 3% for high-quality recycled plastics.
See the Thermal Dryer in Action
Watch how our closed-loop thermal drying tunnel pairs controlled hot air with high-velocity conveying to deliver reliable, low-moisture flakes ready for extrusion.
Working Principle
Thermal dryers utilize hot air to dry the plastic material, much like a hair dryer. After dewatering, the material is vacuumed by a blower and combined with hot air traveling through an extended set of stainless steel tubing. As the plastic spirals within this transport tunnel, moisture is efficiently dehydrated.
Applications & Commercial Impact
Deliver premium, low-moisture flakes that command higher margins and unlock downstream process efficiency across diverse recycling operations.
- Post-Consumer Film Regeneration
Stabilize moisture-sensitive film extrusion by feeding ultra-dry LDPE/LLDPE flakes into pelletizing lines without steam bursts or gel formation.
- Food-Grade PET Reprocessing
Achieve the sub-3% moisture targets demanded by SSP and bottle-to-bottle facilities to preserve IV values and clarity.
- Washed Flake Export Programs
Meet strict overseas quality specs and reduce freight penalties by shipping clean, dry flakes with minimal dust content.
- Integrated Recycling Parks
Balance throughput between washing, drying, and pelletizing cells to eliminate bottlenecks and maintain continuous production.
Key Advantages
- Achieve Low Moisture Levels
The primary function is to reduce moisture to below 3%, making the final material ideal for high-quality pelletizing.
- Improve Final Product Quality
The integrated cyclone separator effectively removes dust and fines, resulting in a cleaner, purer end product.
- Increase Production Efficiency
By thoroughly drying the material, it ensures a stable and efficient process in the subsequent extrusion stage, boosting overall throughput.
- Durable & Reliable Construction
Built with high-quality Type 304 stainless steel, our thermal dryers are designed for longevity and continuous, reliable operation.

Frequently Asked Questions
A dewatering machine (like a centrifugal dryer) removes the bulk of surface water mechanically. However, to achieve the very low moisture content (under 3%) required for high-quality extrusion, a thermal dryer is essential to evaporate the remaining residual moisture using hot air.
A single thermal heater is generally sufficient to reduce moisture to below 3%. For operations that require ultra-low moisture levels (e.g., below 1%), we can configure a system with two or three thermal heaters positioned consecutively.
This system is specifically engineered and optimized for lightweight materials like plastic film and PET flakes. While it may be suitable for other similar materials, we recommend contacting our technical team to discuss your specific material and requirements to ensure optimal performance.
Schedule weekly inspections of blower filters, cyclone outlets, and duct unions. Keeping these components clean prevents pressure drops and preserves target air volume, ensuring consistent moisture removal.
Yes. We supply detailed interface drawings and adapter kits that let you connect to most centrifugal dryers and conveyance systems. Our engineers review your plant layout to match blower capacity and duct routing before shipment.
