YZG round static vacuum dryer

working principle
he so-called vacuum drying is to heat and dry the dried materials under vacuum conditions. If a vacuum pump is used to extract air and moisture, the drying speed will be 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, 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 amount of heat transfer.

◎The heat source for evaporation operation can be low pressure steam or waste heat steam.

◎The evaporator has less heat loss.

◎It can be disinfected before drying, and there is no impurities in the drying process, which meets GMP requirements.

◎It is a static vacuum dryer. Therefore, the shape of the dried material will not be damaged.

Adapt to materials
Suitable for low-temperature drying of heat-sensitive materials that are easy to decompose, polymerize and deteriorate at high temperatures; they are widely used in the pharmaceutical, chemical, food, and electronics industries.

◎When ordering, please choose a suitable vacuum dryer according to the initial moisture content, final moisture content, temperature, vacuum degree, drying capacity, drying time and other factors of the material to be dried. The same type of vacuum dryer has four heating methods: steam, hot water, heat transfer oil, and electric heating. For example, in order to increase the drying capacity, the number of drying racks can be appropriately increased. Please submit to our factory in time.

◎The accessories in the vacuum drying system mentioned in the instruction manual can be provided and installed by our factory for users. Please specify when ordering.

◎The company can provide design, manufacture and installation for the special requirements in the vacuum drying system proposed by users.

◎The company's equipment implements three quality guarantees for users. All accessories are provided for a long time, please rest assured.
