Overview：Tt is well known that vacuum drying is to put raw material under the state of vacuum fo r heating and drying If use vacuum to pump air and humidity out，the dry speed will be faster.
Consulting
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.
WORKING 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.
APPLICATION
This dryer is suitable for drying heat sensitive raw materials that can decompose or polymerize or deteriorate at high temperature. It is widely used in pharmaceutical, chemical, foodstuff and electronic industries.
