Application scope of vacuum cryogenic dryer:
The vacuum cryogenic dryer is suitable for low-temperature drying of thermosensitive materials that are prone to decomposition, polymerization, and deterioration at high temperatures; Widely used in the pharmaceutical, chemical, food, and agricultural industries.
Working principle:
The so-called vacuum freeze low-temperature dryer is to heat and freeze dry the dried material under vacuum low-temperature conditions. If a vacuum pump is used for air and moisture extraction, the drying speed is accelerated.
Note: If a condenser is used, the solvent in the material can be recovered through the condenser; If the 2BV series water ring vacuum pump is used, there is no need for a condenser, saving energy investment.
Product features:
The vacuum cryogenic dryer produced by Yuntai Drying reduces the boiling point of the material solution under vacuum low temperature, which increases the heat transfer driving force of the evaporator, thus saving the heat transfer area of the evaporator for a certain amount of heat transfer.
The vacuum cryogenic dryer can use low-pressure steam or heating steam based on the principles of evaporation operation and freeze-drying.
The evaporator of the vacuum cryogenic dryer has less heat loss.
The vacuum freeze low-temperature dryer can be disinfected before drying, and there are no impurities during the drying process.
