Materials treatment with ProTec's tumble reactor
ProTec designs and supplies innovative solid-state polymer post-condensation lines and complete PET bottle flake recycling lines. The batch tumble reactor which combines homogeneous mixing with short processing times is the keystone of the line. The IV value (intrinsic viscosity as a yardstick for molar mass) of polyesters (PET, PBT, PTT etc.) and of polyamides (PA6, PA66 etc.) can be purposefully increased by precise control of temperature, vacuum and processing time, with or without defined addition of auxiliaries.
The tumble reactor can likewise be used for drying sensitive polymer pellets and granular products in the chemicals and pharmaceuticals industry. Thanks to its design, the drying temperature can be higher than with double-walled bins, so cutting drying times.
