YZG-Circular static vacuum dryer
working principle
The so-called vacuum drying means heating and drying the dried material under vacuum conditions. If a vacuum pump is used for air extraction and humidity removal, the drying speed is accelerated.
Note: If condenser is used. The solvent in the material can be recovered through a condenser. If the solvent is water, the condenser can be eliminated, saving energy investment.
performance characteristics
◎ The boiling point of the material solution decreases under vacuum. Increase the heat transfer driving force of the evaporator. Therefore, the heat transfer area of the evaporator can be saved for a certain heat transfer amount.
◎ The heat source for evaporation operation can use low-pressure steam or waste heat steam.
◎ The evaporator has less heat loss.
◎ Disinfection treatment can be carried out before drying. No impurities will be contaminated during the drying process, which meets GMP requirements.
◎ It belongs to a static vacuum dryer. Therefore, the shape of the dried material will not be damaged.
Adapt materials
It is suitable for low-temperature drying of heat-sensitive materials that are easy to decompose, polymerize and deteriorate at high temperatures; it is widely used in pharmaceutical, chemical, food, electronics and other industries.
