Product description

Pure water has the highest evaporation speed under boiling condition. At normal pressure, pure water starts to boil at the temperature of 100℃, under vacuum condition, as vapor pressure in the system is lower than that of material surface, boiling point of water is under 100℃,e.g. When surface is at 0.07MPa, water will boil at the temperature of 70℃, the higher of vacuum pressure, the lower of boiling point. In the vacuum dryer, evaporated water can be removed quickly by the vacuum system, therefore, this dryer has larger drying capability although it’s under lower operation temperature.

Material is under static conditions during operation of the equipment, which is benefit for keeping initial status of material, intermittent operation can adjust process conditions at any time.

On the top of FZG series dryer, heating system is arranged to tackle the problem of return of condensed water, in addition, air suction is arranged at the side to improve drying efficiency.

This equipment can be used for low temperature drying and solvent recovery, heat sources can be steam, hot water or heat conducting oil.

It is specially suitable for materials that is easily oxygenated during drying.

Main features

It can get higher drying speed at lower temperature and the heat energy can be used fully.

It can dry at low temperature or can dry heat sensitive raw materials.

It can dry raw materials that contain solvent and the solvent needs to recover.

Before drying, it can carry out disinfectant treatment. During the period of drying, any impurity can't enter in it. The dryer belongs to static vacuum one, the shape and volume of raw materials can't be damaged.
