Continuous drying in minutes instead of hours
Kreyenborg Plant Technology
The Infrared Rotary Dryer (IRD; photo) is used for crystallizing and drying virgin or regrind materials for a wide range of plastics. Through the use of the continuously functioning IRD, the need for energy-intensive processing using dry air is completely eliminated, easily resulting in energy savings of an average of 30%, says the company. Raw material is heated directly and gently with IR light, which diverts the vaporizing moisture from the core of the material toward the outside. Clumping is eliminated as the material is conveyed through the machine, and the slow rotation of the drum leads to even heating while avoiding abrasion and breaking of the product, thereby reducing dust formation. Retrofitting of the IRD into existing plants can significantly increase plant throughput and product quality, says the company. Hall 9, Stand A55 — Kreyenborg Plant Technology GmbH & Co.
