Specifications
1. Drying in vacuum condition2. Suitable for drying thermal sensitive materials
3. Can recycle solvent
1. General description of Vacuum Dryer:
In the drying chamber, material will be dried under vacuum condition. Under the vacuum condition, the boiling point of material solution will reduce. It will increase impetus for heat and mass exchange. Therefore for certain heat exchange amount, it can save heat exchange area of evaporator.
Material is under static condition 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 vacuum 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 organic solvent recovery. Heat source can be steam, hot water and thermal oil. It is specially suitable for drying materials that is easily oxygenated during drying.
Following is the layout drawing of a vacuum dryer we sold to Spanish MaxamCorp International, S.L. They use hot water as heating source and need to recycle organic solvent, so we provide to whole system to them.
2. Features of Vacuum Dryer:
1. It can get higher drying speed at lower temperature and then heat energy can be used fully.
2. It can dry at low temperature or can dry eat sensitive raw materials
3. It can dry raw materials that contain solvent the solvent needs to be recovered.
4. Before drying, it can carry out disinfectant treatment. During the period of drying, any impurity can not enter it.
5. The dryer belongs to static vacuum one, the shape and volume of raw materials can not be damaged.
