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–1500 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:
-
infrared rotating drum IRD operates extraordinarily efficiently by direct heat irradiation.
-
Energy consumption can be reduced significantly.
-
infrared rotating drum IRD is the ideal alternative in the face of steadily rising energy costs.
-
The most important components are the radiator module within a horizontal rotating drum, which has an integral, welded, conveyor screw.
-
a volumetric metering unit, into the integral screw of the rotating drum, distributing it evenly through the dryer. T
-
he 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 – 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.
