The so-called vacuum drying means that the drying materials are heated and dried under vacuum conditions. If the vacuum pump is used for air extraction and humidification, the drying rate will be accelerated. Note: If the condenser is used, the solvent in the material can be recovered through the condenser; if SK series water ring vacuum pump is used, the condenser is not needed to save energy investment.
Scope of application:
It is suitable for low temperature drying of thermosensitive materials which are easy to decompose, polymerize and deteriorate at high temperature. It is widely used in drying of thermosensitive materials in medicine, chemical industry, food, electronics, traditional Chinese medicine and other industries.
The boiling point of the material solution in vacuum decreases, which increases the heat transfer impetus of the evaporator. Therefore, the heat transfer area of the evaporator can be saved by a certain heat transfer amount.
Low pressure steam or waste heat steam can be used as heat source for evaporation operation.
Less heat loss in evaporator.
Before drying, disinfection can be carried out, and no impurities are mixed in the drying process, which meets the requirements of GMP.
It belongs to static vacuum dryer, so the shape of drying material will not be damaged.
