The  vacuum drier is suitable for drying heat sensitive raw materials that can decompose and polymerize and metamorphose at high temperature. It is wide used in pharmaceutical, chemical, foodstuff and electronic industries it is well known that   vacuum drying is to put raw material to the state of vacuum for heating and drying. If use vacuum to take air and humidity out, the dry speed will be faster.

Features :

• It belong to static drier. So the shape of raw material to be dried can not be destroyed.
• Under the condition of vacuum, the boiling point of raw material will decrease and make the pushing force become greater. Therefore for a certain amount of heat     radiation, the conducting area of evaporator can saved
• The heat loss of evaporator is less
• Before drying, the treatment of disinfections may be carried out. During the period of drying, there is no impurity material mixing
