eFACTOR3 launches KREYENBORG Infrared Dryer demo line based in Charlotte, NC

07/2022: eFACTOR3, LLC, in tandem with long-standing partner of seven years KREYENBORG, recognized the importance of establishing an infrared drying demo line for North American customers; this goal became a reality, with the recent installation of the new KREYENBORG IR-Batch in the eFACTOR3 facility in Charlotte, NC.

The IR-Batch allows for discontinuous heating, crystallization, drying and coating of batches of different plastics and other bulk materials in minutes instead of hours. The equipment’s application abilities include, crystallizing and drying PET pellets and flakes, crystallizing and drying PLA, and drying and heating PE pellets to remove odors and volatiles. The system is a combination of IR heating and the permanent mixing of the material applicable for the more challenging drying applications, from recycling materials to high performance polymers.

The stainless-steel rotary drum is filled via a pneumatic shut-off valve and the bulk material is heated by the internal infrared module. The mixing elements in the rotary drum are adapted to the bulk material and ensure a good mixing. The machine’s drum is emptied by reversing the direction of rotation.

The IR module including the accessories are mounted on a sliding frame. This frame is pulled out for cleaning and maintenance purposes, allowing easy and quick access to the rotary drum and IR module. The exhaust air is discharged from the rotary drum via a blower. The installed Siemens S7 PLC control has the flexibility for setting residence time, mixing and temperature profile.

The machine is available for small demos and trials at the Charlotte facility and will also be available for short-term rentals.
