PRODUCT SHOW
Pure water has a maximum speed at which vaporization Boiling state. Under normal conditions, about 100 ℃ when the water began to Boiling. And in vacuum conditions, due to the system of water vapor partial pressure of water vapor partial pressure far below the surface of the material, the boiling point of water is less than 100 ℃. For example: the surface down to -0.07MPa, water starts at 70 ℃ Boiling. So, although at a lower operating temperature of the dryer is still a large drying capacity.
Principle
Vacuum Drying is to let the raw material to be dried at vacuum condition. It uses vacuum pump to pump damp air out and make the working chamber form vacuum status. Therefore, the drying speed of raw material is improved and the energy is saved greatly. Notes: The solvent of raw material can be collected by using a condenser. If the solvent is water, the condenser is not required in order to save investment cost.
Features
1. The boiling point of raw material will be decreased under the vacuum condition and make the evaporator increases the pushing force of heat transfer.
2. The heat source can be low pressure steam or waste heat;
3. The loss of the heat during the evaporation is only a little.
4. The disinfection treatment can be carried out before drying and there is no impurity material mixing during drying process. It is in conformity with the requirement of GMP;
5. Static vacuum dryer will not damage the shape of raw materials.
