Infrared Pre-Drying of PET Flakes: Increasing Output and Improving Quality on PET Extruders

>> Improving the manufacturing and physical properties of recycled, food-grade PET through technology powered by infrared light has a crucial part to play in the intrinsic viscosity (IV) property

Pre-crystallization and drying of the flakes prior to extrusion helps minimize the loss of IV from PET, a critical factor for reuse of the resin

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 80W/KG/H), and shearing in the extruder is thereby also reduced because the preheated material enters the extruder at constant temperature”

>> Improving the output of PET Extruder

An increase of the bulk density by 10 to 20 % can be achieved in the IRD, improves the feed performance at the extruder inlet substantially – while the extruder speed remains unchanged, there is a substantially improved filling performance on the screw.
