Plastic dehumidifier for PET Filament machine,PET plastic Filament extruding machine,PET Broom making machine

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 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.


IRD Dryer

Traditional Dryer

Transfer mediumNoneHot air
Heat transferBoth inside & outside particles together.From outside to inside particle gradually.
EnergySave at least 20~50% energy compared to traditional dryer.Consume much energy.
Process time1. Crystallization & drying: They are processed simultaneously within about 8~15 minutes.
2. Drying and crystallization at a time
1. Crystallization: About 30~60 minutes.
2. Drying: About 4~6 hours.
Moisturecontent1. Under 50-70 PPM after IRD processed.
1. Spend 30~60 minutes to change amorphous PET to crystallized PET first.
2. Under 200PPM after about 4 hours dehumidifier processed.
3. Under 50 PPM after about more than 6 hoursdehumidifier processed.
Lead time20minsMore than 6 hours.
Material changeover1. Easy & faster.
2. There are only 1~1.5 times capacity of material hourly consumption in the buffer hopper.
1. Difficult & slowly.
2. There are 5~7 times capacity of material hourly consumption in the crystallizer & hopper.

Simple--- By Siemens PLC control

It is difficult such as it must put a little crystallized PET in the crystallizer when beginning operation.
Maintenance1. Simple.
2. Lower maintenance cost.
1. Difficult.
2. Higher maintenance cost.
