Because of its diversity of needs, HHV has been designing and manufacturing variety of vacuum drying oven suits customer specific applications. These vacuum drying ovens are being used to achieve rapid drying at low temperature, including the drying of deep pores, in a way that does not damage the products. In these vacuum drying ovens, the dried material is exposed to a vacuum, thus reducing the boiling point and leading to water evaporation even at low temperatures.
