1.CE certificate. 2. China patent certificate. 3. With last moisture to be 100-150PPM. 4. Drying and crystallization for 15 minsIn comparison to conventional dry-air systems, the infrared rotating drum IRD operates extraordinarily efficiently by direct heat irradiation. Energy consumption during production can be reduced significantly. The infrared rotating drum IRD is the ideal alternative in the face of steadily rising energy costs.
The most important components of the infrared rotating drum IRD are the radiator module within a horizontal rotating drum, which has an integral, welded, conveyor screw.
The material to be processed is fed continuously, by a volumetric metering unit, into the integral screw of the rotating drum, distributing it evenly through the dryer. The dwell time depends on the rotational speed of the drum and is adapted precisely to the operational parameters.
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 are employed in varied applications – conceivable fields of application are virtually unlimited and can be found both in the 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

Competitive Advantage:
The classic applications for the infrared rotating drum are crystallisation and drying plants for PET pellets and flakes/regrind. Granulated foil stock from thermo-forming, and post-consumer bottle reclaim is processed at throughput rates from 100 kg/hr–1500 kg/hr. As an alternative the flakes can be mixed with virgin granules – separation does not take place in the rotating drum.
A significant potential for IRD technology is the drying of PLA, 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.
In addition to drying, pure heating processes are also ideal applications, as pellets can be heated, in the rotating drum (while being agitated), to close to the melt temperature without agglomerates forming. Infrared rotating drums are also employed in processes in which volatile components or residual oligomeres need to be extracted from the product. Another heating application is the heating of shear sensitive materials before plasticising in the extruder, (especially in cold climates).
