Drying and crystallization of PET Recycled flake 

Processing Explanation:

lDry and crystallize of PET Recycled flake to 70ppm

lProcess temperature 180 °C to 220 °C

lDischarging and feed to Extruder feeding hopper

Can cooperate with the machine line:

lPET Extruding pelletizing machine line

lPET Sheet making machine line

lPET Mono filament fiber making machine

lPET Meltblown fabric making machine

lPET Bale strap making machine line

Our IRD ( Infrared Dryer ) will make for you:

lInfrared rotary dryer is designed with sophisticated temperature measurement. The material and exhaust air temperature are continuously monitored by sensors.

  If there is any deviations,PLC system will adjust automatically

lThere are flexible 5 zone heating control

lAdopt drum rotation will make sure the constant movement of the raw material to avoid clumping/sticking and dry evenly

lWithin 20mins to get the moisture 150ppm or less ( Depends on customer’s requirement)

lTo get the crystallization level at 20%-30% of the pellets without lumping/sticking)

lComprehensive visualization of all process parameters

Our IRD working processing:

1. Material Feeding

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.

Our Advantage 





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.



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.



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.



Ensures a constant discharge
