Principle & Functions
The infra-red rays causes molecular heat oscillation acting directly to the core of the particles from the inside-out so the moisture inside the particles are quickly heated and vaporized into the circulating ambient air to remove the humidity at the same time. |
 |
It provides continuous processing of PET flake, reducing moisture from over 4,000 ppm to less than 50 ppm in tens of minutes, compared to 5-6 hours for conventional systems. It is significant benefit for PET material crystallizing and drying as well as the short exposure to heat in the IRD to preserve IV properties. |
IR Drying
Heat is absorbed inside the particle because the plastic and moisture are excellent IR absorbent so that the drying takes a short time.
Heating; Crystallizing and Drying are in the interior particle.
Advantages In Comparison To Conventional Systems
- Up to 60% less energy than conventional drying systems
- Time and space savings
- Faster start-up and quicker shut down
- Fully continuous process
- Careful material treatment
- No segregation of products with different bulk densities
- High efficiency
- Simple handling and installation
Infrared Rotary Drum (IRD) Process
The Drum has an internal helix that pushes the material forward when rotating; at the same time the material passes under the IR radiators for drying.
The output needed will size the drum diameter and length together with the radiation power. Exposure time and temperature are controlled by the speed and the IR power applied during the process.
IRD Specification
- Application: 50% virgin + 50% regrind APET
- Bulk density: 0.75 g/cm3 + 0.4 g/cm3
- Initial material moisture: virgin 4,000ppm; regrind 6,000ppm*
