Under vacuum conditions, the boiling point of the material solution is lowered, which increases the heat transfer driving force of the evaporator. This allows for a reduction in the required heat transfer area for a given amount of heat transfer, saving evaporator surface area.
The heat source for evaporation can use low-pressure steam or waste heat steam, resulting in minimal heat loss from the evaporator.
Disinfection can be performed before drying, and no impurities enter during the drying process, meeting GMP requirements.
It is a static vacuum dryer, so the shape of the dried material is not damaged.
Vacuum drying refers to heating and drying materials under vacuum conditions. Using a vacuum pump to extract air and moisture accelerates the drying process.
