Pre-crystallization and dryer for PET chips/scraps/pellets for PET
/PLA Sheet extrusion machine line
Field of applications.
Heating.Heating granules and regrind material prior to further processing
(e.g. PVC, PE, PP,…) inter alia to improve the throughput in the
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
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
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
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)|
Allow for easy and fast cleaning.
Rapid product change-over
HOW TO ENSURE THE QUALITY!
● In order to ensure the accuracy of each part, we are equipped
with a variety of professional processing equipment and we have
accumulated professional processing methods over the past years.
