Drying and crystallization of CO-PBT and CO-PET pellets

Drying and Crystallization of CO

Processing explanation

Dry and crystallize of amorphous Co-PBT and Co-PET Pellets to 150ppm

Process temperature 80 °C to 135 °C

Cooling the pellets to 40°C ( Re-cooling the pellets to avoid the pellets re-moistured )

Transfer to bagging package

Our IRD ( Infrared Dryer ) will make for you

The infrared rays caused molecular heat oscillation acting directly to the core of the particles from the inside-out, the moisture inside the particle are quicly heated and vaporized into the circulating ambient air to remove the humidity at the same time.

Infrared 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

There are flexible 5 zone heating control

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

Within 20mins to get the moisture 50-150ppm or less ( Depends on customer’s requirement)

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

Comprehensive visualization of all process parameters

Cooling the pellets to 40°C (Re-cooling the pellets to avoid the pellets re-moistured )

Our IRD working processing

Infrared crystal dryer continuous 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

1 Low energy consumption Significantly lower energy consumption compared to conventional processes, through the direct introduction of infrared energy to the product.
2 Minutes instead of hours The product remains for only a few minutes in the drying process and is then available for further production steps.
3 Instantly The production run can start immediately upon startup. A warm-up phase of the machine is not required.
4 High efficiency The energy is immediately brought into the core of the product.
5 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.
6 Easy cleaning Good access to all components allows for easy and fast cleaning. Rapid product change-over.
7 In one step Crystallization and drying in one step
8 Increased throughput Increase of plant throughput by means of reduced load on extruder.
9 Evenly Ensures a constant discharge
