About KREYENBORG
KREYENBORG GmbH & Co. KG has been developing and manufacturing machines and turnkey process plants for the processing of food, plastics and other bulk materials at its Senden site in the Münsterland region for over 70 years. Core products are infrared rotary drum systems such as the FoodSafety-IRD for sterilization, pasteurization, roasting, drying and coating of grains, seeds, nuts, herbs and spices. In the plastics sector, the company supplies systems for drying, crystallization and decontamination of rPET flakes for food contact (IR-CLEAN® without vacuum technology) as well as for odor minimization, together with mixers, special silos, extruder feeding systems, big bag stations and underwater pelletizing systems. The portfolio of services includes engineering, process consulting, process validation, assembly, commissioning as well as service, maintenance, remote service and spare parts. In a technical center in Senden, customers can carry out trials with their own products; sales are handled worldwide via sales partners.
