Drying and Crystallization of PET chips/scraps/pellets for Sheet extrusion

If you use Twin-screw or Multi screw extruder with vacuum degassing system, why still need to use Infrared crystal dryer to work together?

• Continuous material feeding into Sheet extruder
• Increased output: up to 50% higher
• Increased bulk density of material: normally 20-50% depends on material type
• Reducing the complexity of vacuum system
• Increased stability of the operation of extruding line and product quality
• Lower requirement for raw material used
• Low down the operation cost up to 20% compared to the systems without IRD (Infrared crystal dryer )

Our processing

Normally the PET Bottle flakes or sheet scrap with initial moisture level of up to 10000-13000ppm. The PET Bottle flakes or sheet scrap (Virgin or mixed ) will be recrystallized in a continuous IRD in 10-15mins, the drying temperature will be 150-180℃and dried to 1000ppm,then fed to Double screw extruding system for further processing

l Limiting the hydrolytic degradation of the viscosity.

l Prevent increasing AA levels for materials with food contact

l Increasing the capacity of the production line up to 50%

l Improvement and make the product quality stable-- Equal and repeatable input moisture content of the material

Processing explanation

Continuously processing ( Production without interruption with PET Sheet production line )

1. Filling

By vacuum dosing feeder to convey the raw material continuously to the rotating drum

2. Drying and Crystallization

Thermal treatment and mixing. There are the spirals welded into the rotary drum to ensure the well mixture of material and continuous transfer to the outlet. And the material will also be dried continuously

3. Discharging

The dried and crystallized material will be discharged after minutes drying by drum rotary. Finally the dried and crystallized material will be conveyed to the next processing.
