Pre-crystallization and dryer for PET chips/scraps/pellets for PET /PLA Sheet extrusion machine line
Heating.Heating granules and regrind material prior to further processing (e.g. PVC, PE, PP,…) inter alia to improve the throughput in the extrusion.
Crystallization.Crystallisation of PET (Bottleflakes, granules, flakes), PET masterbatch, co-PET, PBT, PEEK, PLA, PPS, etc.
Drying.Drying of plastic granules, and –ground material (e.g. PET, PBT, ABS/PC, HDPE, LCP, PC, PP, PVB, WPC, TPE, TPU) as well as other free-flowing bulk materials.
Coating.Coating of adhesives (e.g. Hot melt, EVA+lime,…)
High input moisture.Drying processes with high input moisture >1%.
Diverse.Thermal processes for the removal of rest oligomeren and volatile components.
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 Infrared crystal dryer in 20mins, the drying temperature will be 150-180℃ and dried to 50-70ppm,then fed to Single 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
1. Material 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.
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. Rapid product change-over |
