OEM/ODM PET Flake/scrap dehumidifier crystallizer Manufacturer, Supplier

Reprocessing the flakes in the extruder reduces IV due to hydrolysis i the presence of water, and that’s why pre-drying to a homogeneous drying level with our IRD System can limit this reduction. In addtion, the resin does not yellow because drying time is reduced ( Drying time only needs 15-20mins, final moisture can be ≤ 50ppm, energy consumption less than 60W/KG/H), and shearing in the extruder is thereby also reduced because the preheated material enters the extruder at constant temperature”

Frequently Asked Questions

What is the processing time for PET flakes?It takes approximately 20 minutes for both crystallization and drying.
Does the system save energy?Yes, it consumes up to 60% less energy than conventional drying systems.
Is the operation manual or automatic?It is fully automated via a Siemens PLC control touch screen.
Can the temperature be adjusted?Yes, temperature and drying time are independently set based on raw material properties.
Is the moisture level consistent?Yes, the output moisture is typically reduced to 50-70ppm consistently.
