The liquid low temperature vacuum dryer manufacturer tells you the operating requirements and material constraints of the double cone rotary vacuum dryer


The characteristics of materials have their own advantages and disadvantages for drying treatment. Some products have short drying time, low drying residue, and naturally higher work efficiency. For some toxic or easily eroded materials, many factors need to be considered. During processing, the vacuum environment of the double-cone rotary vacuum dryer greatly reduces the boiling point of the liquid that needs to be removed, so vacuum drying can be easily applied to heat-sensitive substances. Gas components that can be extracted from raw materials. If the workpiece is heated first, the gas will expand when heated.

Because the sealing of the vacuum box is very good, the infinite pressure generated by the expansion gas may burst the tempered glass of the observation window. This is a potential risk. This risk can be avoided by operating in the order of first vacuuming and then heating.

If you operate in the order of heating up first and then vacuuming, when the heated air is pumped out by the vacuum pump, the heat will definitely be carried to the vacuum pump, which will cause the temperature of the vacuum pump to rise too high, which may reduce the power of the vacuum pump. The heated gas is directed to the vacuum gauge, which causes a temperature rise. If the temperature rise exceeds the specified operating temperature range of the vacuum pressure gauge, it may cause the vacuum pressure gauge to show an error.

Therefore, there are many matters that need to be paid attention to. It is necessary to strictly strengthen the supervision of the drying program to prevent accidents and improve the drying efficiency of the double cone rotary vacuum dryer.
