Plastic low temperature dryer

Plastic low temperature dryer/Rotary drum crystal Infrared dryer / PET dehumidifier Equipment for PET flake / regrind

• crystallisation and drying plants for PET pellets and flakes / regrind.
• Granulated foil stock from thermo-forming,
• 100 kg/hr–500 kg/hr post-consumer bottle reclaim .
• can be mixed with virgin granules – separation does not take place in the rotating drum.
• drying of PLA IRD technology , for virgin, granulated or mixed feedstocks.
• The continual movement of the material in the infrared rotating drum is ideal for, particularly, PLA granulated stock, which tends to easily stick together in the crystallisation phase at T = 60 °C.
• close the melt temperature without agglomerates forming.
• employed in processes in which volatile components or residual oligomeres need to be extracted from the product.
• heating shear sensitive materials before plasticising in the extruder, (especially in cold climates).

More Detail:

1. infrared rotating drum IRD operates extraordinarily efficiently by direct heat irradiation.
2. Energy consumption can be reduced significantly.
3.  infrared rotating drum IRD is the ideal alternative in the face of steadily rising energy costs.
4. The most important components are the radiator module within a horizontal rotating drum, which has an integral, welded, conveyor screw.
5. a volumetric metering unit, into the integral screw of the rotating drum, distributing it evenly through the dryer. T
6. he dwell time depends on the rotational speed of the drum and is adapted precisely to the operational parameters.
7. At the end of the rotating drum the material falls into the output hopper and can be transferred directly to the next process step.

Applications:

• Infrared rotating drums IRD –  virtually unlimited and  plastics and other industries.

• drying of plastic pellets (e.g. PET, ABS/PC, PC, LCP, wood-PP, PP/PE compounds)
• crystallisation and drying of PET, PPS, PLA (reclaim/pellets)
• drying processes with high initial moistures > 1 %
• heating of pellets and reclaim before further processing (e.g. PVC, PE) for example to increase the extruder throughput
• heating processes for removing residual oligomeres and volatile components
• drying in the food, feed and pharmaceutical industries
• roasting of coffee beans.

Specifications:

We test the moisture with German made Sartorius moisture test instrument
