Drying and Crystallization of PET chips/scraps/pellets for PET /PLA Sheet extrusion machine line
If you use Twin-screw or Multi screw extruder with vacuum degassing system, why still need to use Infrared crystal dryer to work together?
Heating.Heating granules and regrind material prior to further processing (e.g. PVC, PE, PP,…) to improve
throughput in the extrusion process.
Crystallization.Crystallization of PET (Bottle flakes, 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.Heating processes for the removal of rest oligomers 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 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
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.
Low energy consumption.Significantly lower energy consumption compared to conventional processes, through the direct introduction of infrared energy to the product.
Minutes instead of hours.The product remains for only a few minutes in the drying process and is then available for further production steps.
Instantly.The production run can start 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 heated gently from the inside to the outside and not loaded from the outside for hours with heat, and thereby possibly damaged.
Easy cleaning.Good access to all components allows for easy and fast cleaning. Rapid product change-over.
In one step.Crystallization and drying in one step.
Increased throughput.Increase of plant throughput by means of reduced load on extruder.
Evenly.Ensures a constant discharge.
Filling.By means of volumetric dosing, the material to be processed is conveyed continuously through the rotating drum.
Conveying.Mixing. Thermal treatment. A spiral welded into the rotary drum ensures a mixture of material and continuous transfer to the outlet. The material is thus thermally treated continuously.
Outlet.In minutes instead of hours, the material automatically leaves the rotary drum and can be transferred directly to the next processing step.
