Principles of square vacuum dryer working principles
The so -called vacuum drying is to heat the drying material under vacuum conditions for heating and drying. If the vacuum pump is used to use the vacuum pump, the drying speed is accelerated.
Note: If the condenser is used. The solvents in the material can be recycled by condenser. If the solvent is water, no condenser can save energy investment.

Performance characteristics of square vacuum dryer
◎ The boiling point of the material solution under the vacuum is reduced. Increase the heat transfer driving force of evaporator. Therefore, a certain heat transfer can save the heat transfer area of ??the evaporator.
◎ The heat source of evaporation operation can be low -pressure steam or waste heat steam.
◎ The evaporator has less heat loss.
◎ Disinfection treatment can be performed before drying. There are no unsustaining in the process of drying, which meets the GMP requirements.
◎ It is a static vacuum dryer. Therefore, the shape of the dry material will not be damaged.
Square vacuum dryer adaptation material
The square vacuum dryer is suitable for the low temperature and drying of thermal materials that are easy to decompose at high temperature, aggregate and deteriorated thermal materials; it is widely used in the pharmaceutical, chemical, food, electronics and other industries.

Ordering Instructions
◎When ordering, please select a suitable vacuum dryer based on the physical properties of the dried material, initial moisture content, final moisture content, temperature, vacuum, drying volume, drying time and other factors. The same model of vacuum dryer has four heating methods: steam, hot water, thermal oil, and electric heating. For example, in order to increase the drying volume, the number of drying racks can be appropriately increased. Please inform our factory in time.
◎In the instruction manual, our factory can provide and install the accessories in the vacuum drying system mentioned above. Please specify when ordering.
◎Our company can provide design, manufacturing and installation for special requirements of the vacuum drying system proposed by users.
◎Our equipment implements three quality guarantees for users. All accessories are provided for a long time, please rest assured.
