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 woking processing
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
Low energy consumption.Significantly lower energy consumption compared to conventional processes, through the direct introduction of infrared energy to the product.
Minutes instead hours.The product remains for only a few minutes in drying process and is then available for further production steps.
Instantly.An immediate start of the production run is possible immediately upon startup. A warm-up phase of the machine is not required.
High efficiency.The energy is immediately brought into the core of the product.
Gently.The material is gently from the inside to the outside heated and not loaded from the outside for hours with heat / damaged.
Easy.Good access to all components allows for easy and fast cleaning. Rapid product change-over.
In one step.Crystallization and drying in one step.
Increase throughput.Increase of throughput of the plant through relief of the extruder.
Evenly.Ensuring a constant discharge.
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 |
