Removal of moisture under cost-optimized conditions

Vacuum drying produced at low cost

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

Highly efficient drying with modular systems

Technical data
