Vacuum drying

Vacuum drying: suitable for temperature-sensitive substances

Vacuum drying is characterized by fast drying times at low temperatures. We apply this contract drying method to materials that are sensitive to temperature or tend to cake. As the name implies, a vacuum dryer removes the pressure on drying compartment: it creates a vacuum. Together with gentle heat, the liquid in the material evaporates. We recondensate the liquids after having filtered the gas stream. The result is a gently and homogeneously dried product.
