Machine Processing

Pre-crystallization and drying of the flakes prior to extrusion helps minimize the loss of IV from PET, a critical factor for the reuse of the resin. Reprocessing the flakes in the extruder reduces IV due to hydrolysis in the presence of water; our IRD System limits this reduction by ensuring a homogeneous drying level.

Key Performance Data:
Drying time only needs 15-20 mins, final moisture can be ≤ 50ppm, and energy consumption is less than 80W/KG/H. Preheating the material ensures constant temperature entry, reducing shearing in the extruder.

Infrared Pre-Drying Benefits

Improving the manufacturing and physical properties of recycled, food-grade PET through infrared technology plays a crucial role in maintaining intrinsic viscosity (IV).

Improving PET Extruder Output

An increase of bulk density by 10 to 20% can be achieved in the IRD, significantly improving feed performance at the extruder inlet and enhancing filling performance on the screw.
