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 )
Drying and Crystallization of PET chips/scraps/pellets

lContinuous material feeding into Sheet extruder
lIncreased output: up to 50% higher
lIncreased bulk density of material: normally 20-50% depends on material type

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
lLimiting the hydrolytic degradation of the viscosity.
lPrevent increasing AA levels for materials with food contact
lIncreasing the capacity of the production line up to 50%
lImprovement 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. Material Feeding
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.
Advantage of IRD Processing
1 | Rotary drum design | To dry the material evenly |
|
| The spiral coils design of the drum ensure the good mixture of the raw material to avoid material clumping |
2 | Retention time | Depends on the speed of Rotary drum |
|
| The speed can be adjustable by the property of drying material |
3 | PLC Controlling system | The material retention time,drum rotating speed |
|
| The Infrared lamps performance, drying temperature |
|
| The feeding speed of Vacuum feeder |
4 | Reproducibility | Recipes and process parameters can be stored in the controlling system to ensure opimal and reproducible results |
5 | In one step | Drying and crystallization in one step |
6 | High efficiency | Minutes drying and crystallization instead of hours( Compared to conventional dehumidifier and crystallizer) |
7 | Fast cleaning | Allow for easy and fast cleaning. |
