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


 


Processing Explanation

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

lProcess temperature 80 °C to 135 °C

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

lTransfer to bagging package 


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 50-150ppm 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

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

 

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.

No

Description

 

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
