Reaching of crystallization level of 30 ppm. Inline crystallization and drying of amorphous pellets for fast line start-up. Prevent material clumping and adhesion.
Special infrared drum dryer design (continuous or batch process) for uniformly heating of material to 175 °C (10-15 minutes). Subsequently, the material is transferred to a conventional hot air dryer for further moisture reduction to below 30 ppm (about 90 minutes).
Variable temperature, mixing energy and volume
Significantly reduced dwell time in dryer
Processing of amorphous PET strand pellets possible
small production lots can be processed economically
