FZG Square Static Vacuum Dryer
How It Works
Vacuum drying involves heating and drying the material under vacuum conditions. If a vacuum pump is used to extract air and moisture, the drying speed is accelerated.
Note: If a condenser is used, the solvent in the material can be recovered through the condenser; if the solvent is water, the condenser can be omitted to save energy investment.
Performance Features
◎Under vacuum, the boiling point of the material solution decreases, increasing the heat transfer driving force of the evaporator. Thus, for a certain heat transfer amount, the heat transfer area of the evaporator can be saved.
◎The heat source for evaporation can be low-pressure steam or waste heat steam.
◎The evaporator has low heat loss.
◎Sterilization 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 drying material will not be damaged.
Applicable Materials
Suitable for low-temperature drying of heat-sensitive materials that are prone to decomposition, polymerization, and deterioration at high temperatures; widely used in pharmaceutical, chemical, food, electronics, and other industries.
