Drying is the single most important variable in the processing. We work closely with resin suppliers and processors to develop equipment and procedures that eliminate moisture-related quality issues while maximizing energy efficiency.
- Adopt rotation drying system to ensure uniform drying.
- Excellent mixing capability preventing sticking or clumping during processing.
- No segregation of products with different bulk densities.
Energy Consumption & Performance
Our IRD users report energy costs as low as 0.08kwh/kg without sacrificing quality. Key advantages include:
- Total process visibility through advanced PLC control systems.
- Achieve 50ppm moisture levels in just 20 minutes via one-step drying & crystallization.
- Wide range of industrial applications.
- Limit hydrolytic degradation of viscosity.
- Prevent increasing AA levels for food-contact materials.
- Increase production line capacity by up to 50%.
Process Technology
1. Initial Heating: Slow drum rotation with high infrared lamp intensity to rapidly raise resin temperature to the preset target.
2. Drying & Crystallization: Drum speed increases to prevent clumping. Infrared power is optimized to finish the process efficiently within 15-20 minutes.
3. Automatic Discharge: The system automatically discharges material and refills the drum for the next cycle, with all parameters saved as recipes in the touch screen control.
Frequently Asked Questions
Q: What final moisture levels can be achieved?
A: We consistently reach ≤30ppm for PET, even with initial moisture levels between 6000-15000ppm.
Q: Is a pre-dryer necessary for vacuum degassing extruders?
A: Yes, using a pre-dryer is highly recommended to stabilize product quality, prevent viscosity degradation, and maintain consistent material input.
Q: Can you help test new materials?
A: Yes, our dedicated Test Center allows for continuous or discontinuous experiments to determine precise drying parameters for your specific materials.
Q: What is the typical lead time?
A: The delivery time is approximately 40 working days after receipt of the deposit.
Q: How is the system installed?
A: We offer on-site installation support by experienced engineers or remote technical guidance via online channels.
Q: What materials can be processed?
A: The system supports PET, PLA, PBT, ABS/PC, HDPE, LCP, PP, PVB, TPU, and many other engineering plastics for various sheet, film, and monofilament extrusion lines.
