Working Principle
Vacuum drying refers to the process of drying materials under vacuum conditions while heating. If a vacuum pump is used to extract moisture, it accelerates the process.
Enhanced drying speed.
Note: If a condenser is used, the solvent in the material can be recovered through the condenser. If the solvent is water, a condenser is not necessary, thereby saving on energy investment.
Performance Features
The boiling point of the material solution is reduced under vacuum, which increases the driving force for heat transfer in the evaporator. Consequently, for a given amount of heat transfer, the heat transfer area of the evaporator can be saved.
The heat source for the evaporation process can be low-pressure steam or waste heat steam.
◎ Evaporator heat loss is minimal.
Can be disinfected before drying, ensuring no impurities enter during the drying process, in compliance with GMP standards.
◎Static vacuum dryer; thus, the shape of the dried material will not be damaged.
Suitable Material
Low-temperature drying suitable for thermosensitive materials that are prone to decomposition, aggregation, and deterioration at high temperatures; widely used in industries such as chemicals, food, and electronics.
