Kreyenborg GmbH said its infrared drum, or IRD, technology does efficient heating, crystallization and drying of PET resin, with a low level of stress to the material.
The short waves of infrared drying heats up the material from the inside, which cuts energy consumption, Kreyenborg said.
Now, the company has rolled out a new dryer with a new infrared module. Individual infrared radiators use an integrated reflector of aluminum oxide. The lining of the air-cooled module is made of ceramics.
The improvements should increase the reliability and lifespan of the module, Kreyenborg said.
For the controller, the machinery maker is working with control maker BSG Bruckmann Steuer¼ungstechnik GmbH. The controller is an intuitive touch-screen unit with optimized temperature control.
Kreyenborg of Munster, Germany, is targeting the dryer and crystallizer to PET and polylactic acid. The company has sold four IRD machines to PLA producers.
