1. The boiling point of the material solution in the vacuum decreases, so that the heat transfer driving force of the evaporator increases, so the heat transfer area of the evaporator can be saved by a certain heat transfer.
2. The heat source of evaporation operation may use low pressure steam or waste heat steam;
3. Less heat loss of evaporator;
4. Before drying can be disinfected treatment, drying process are mixed with pure things, in line with GMP requirements;
5. Belonging to the static vacuum dryer, so the shape of the dry material will not be damaged;
6. The use of condenser, can effectively recover the solvent in the material.
