Vacuum Drying Oven

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.
Drying usually refers to the removal of liquids from a subject via evaporation or vaporization.
In drying processes that use convection, the vapour pressure of liquid that is to be expelled at a certain temperature or pressure is critical. If the vapour pressure is identical to or less than the liquid content in the atmosphere, no drying is possible.
