Achieving low residual moisture, especially with porous particle structures, requires long drying times, high drying temperatures or a high vacuum. Temperature-sensitive products often cannot be dried efficiently or only with difficulty.
Vacuum drying offers the advantage of a low temperature stress with fast drying times. Due to the previous system configurations, vacuum drying was an functioning but expensive process. The existing plant designs could only be operated with considerable investment costs. To reduce this cost structure, Ebbecke Verfahrenstechnik AG has developed a new vacuum drying system so that large quantities of the dry material can be dried with a flexible and modular system. This results in cost savings of up to 40 % for comparable products.
