IRD Crystallizing & Drying Handling System
Infrared drying system for plastic material or other in fast drying process.
- Application: 30% virgin + 30% regrind APET from in-house + 40% regrind APET from post consumed
- Buck density: virgin 0.75 g/cm3 + regrind 0.4 g/cm3
- Initial material moisture: virgin 0.4%; regrind 0.6%
- Handling capacity: 200~2,200 kgs/hr
- Process time: 12 min. (approximate)
Features
Sunwell Global’s IRD Crystallizing & Drying Handling System is designed for efficient processing of PET sheet, film extrusion, and injection molding, especially when using post-industrial or post-consumer regrind. This infrared drying system is also ideal for polyester fiber processors, offering faster performance compared to traditional drying methods.
- Direct Infrared Heat Application: Infrared rays generate molecular heat oscillation, heating particles from the inside out, effectively reducing moisture from over 4,000 ppm to less than 50 ppm in minutes.
- Rotary Drum Design: The infrared rotary dryer features a stainless steel drum with an internal helix, ensuring all surfaces of the materials are evenly exposed to infrared rays for consistent drying and crystallizing.
- Precise Control: Adjustable drum speed and infrared power provide precise temperature and exposure time management, preserving the intrinsic viscosity (IV) properties of PET materials during processing.
Benefits for PET Processing
- This infrared drying system offers continuous processing, drastically reducing drying times from hours to minutes.
- It is ideal for PET sheet extrusion, film extrusion, and injection molding, ensuring high efficiency in drying and crystallizing PET flakes while maintaining material integrity.
