Working principle

The so-called vacuum drying, that is, drying materials under vacuum conditions for heating drying. If the vacuum pump is used for pumping and exhausting, the drying speed is accelerated.

Note: if the condenser is used, the solvent in the material can be recovered by the condenser. For example, the solvent is water, the condenser can not be used, and the energy investment is saved.

Performance characteristics
◎The boiling point of raw material under vacuum. Reduce the heat transfer of the evaporator force increases. Therefore for a certain amount of heat can save the heat transfer area of evaporator.
◎The heat source for evaporation can be steam or waste heat steam.
◎Less heat loss of evaporator.
◎Disinfection can be carried out before drying, without any impurity in the drying process, and comply with the requirements of GMP.
◎The utility model belongs to a static vacuum drier, so the shape of the dried material can not be damaged.

Adaptive material
  Suitable for easy decomposition under high temperature, dry heat sensitive material polymerization and metamorphose; it is widely used in pharmaceutical, chemical, food, electronics and other industries.

Note: water ring vacuum pumps are combined with mechanical supercharging to increase vacuum.

Order note

◎When ordering, please select the appropriate vacuum dryer according to the physical properties, initial moisture content, final moisture content, temperature, vacuum, drying capacity and drying time of the drying material. In the same type of vacuum drier, there are four heating ways: steam, hot water, heat conduction oil and electric heating.For example, in order to increase the drying capacity, we can increase the number of drying racks properly. Please put forward to our factory in time.
◎We can supply and install the accessories in the vacuum drying system described above in the instruction manual. Please explain when ordering.
◎We can provide the design, manufacture and installation of the special requirements of vacuum drying system.
◎The company's equipment for users of quality Three Guarantees. All accessories, long-term supply, please rest assured that users.
