vacuum dryer / mixer / granulator / cooler

Intensive mixing prevents temperature and moisture gradients in the product
High heat transfer means more effective drying
Gentle thermal treatment of the product under vacuum
Multiphase process (mixing,granulating, drying, cooling)
Economical solvent recuperation

Machine Type

Lödige DRUVATHERM® Shovel Dryers are batchprocess vacuum dryers. The main shaft with shovels is regulated by frequency converter to achieve an optimal adjustment to the process. The special mixing elements rotate in the cylindrical drum, which is equipped with a heating/cooling jacket, and generate a three dimensional movement of the product (mechanically generated fluid bed). The resultant frequent contact of particles with the heat transfer surface reduces the drying times to a minium.
