Vacuum Drying Machine

Vacuum Drying Machine

Working Principle and Features of the Vacuum Drying Machine
Pure water has the highest evaporation speed under boiling conditions. At normal pressure, pure water starts to boil at 100℃. In a vacuum, this boiling point can be reduced greatly, and the higher of vacuum pressure, the lower of boiling point. In the vacuum drying machine, evaporated water can be removed quickly by the vacuum system. Therefore, this dryer has larger drying capability although it operates at a lower temperature.

The raw material is under static conditions during operation of the equipment, which is a benefit for maintaining the initial status of material. Intermittent operation can adjust process conditions at any time.
The FZG vacuum drying machine heating system is designed to tackle the problem of the return of condensed water. In addition, air suction is applied at the side to improve drying efficiency.

This equipment can be used for low temperature drying and solvent recovery, and the heat source used can be steam, hot water, or heat conducting oil.
The vacuum drying machine is especially suited for materials that are easily oxidized during drying.
