Pharmaceutical vacuum drying machine vacuum tray dryer

Description of Vacuum Tray Dryer

Vacuum drying is that materials are heated and dried under vacuum. It uses vacuum pump to pump air and humidity out to make the studio in vacuum, thus accelerating the drying speed as well as saving energy.
Note: a condenser can be used to recover solvent in the materials. But if the solvent is water, there is no need to use condenser so as to save energy investment. 

Suitable for drying heat sensitive raw materials that can decompose and polymerize and metamorphose and deteriorate under
high temperature in pharmaceutical, chemical, food and electronic industries.
The boiling point of the material solution under vacuum is reduced. 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 the evaporation operation may use low pressure steam or waste heat steam.
The evaporator has less heat loss.
It can be disinfected before drying. There is no impurity in the drying process, which meets GMP requirements.
is a static Vacuum Dryer. Therefore, the shape of the dried material will not be damaged.

Features of vacuum Tray Dryer

The advantages are fast drying speed, little pollution and good product quality. The oven keep the work space vacuum and dry by
vacuum pump, which helps reduce the boiling point and fasten drying speed.
It works under the negative pressure with less oxygen content, which can reduce or eliminate the oxidation reaction.
Under the negative pressure, boiling point is reduced, and it avoids the damage of material's quality.
If solvent is toxic or valuable, the gas can be condensed and recycled.

Application of Vacuum tray dryer

This machine is mainly used for drying fruits, vegetables, herbal plants, herbal extracts, heat sensitivity materials such as explosive, the materials that state is not stable and shape is easy to be destroyed, the materials that need to recover organic solvent such as ethanol, etc.
