It 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 electronic industries.
feature
Under the condition or vacuum,the boiling point of raw material will decrease and make the pushing force become greater.Therefore for a ceratin amount of heat radiation,the conducting area of evaporator can ve saved.
The heat souce for operation of evaporation may be low pressure steam or surplus heat steam.
The heat loss of evaporator is less;
Before drying,the treament of disinfection may be carried out.During the peried of drying,there is no impurity material.It is in conformity with the requiyrement of GMP;
It belongs to static drier.So the shape of raw material to be dried can not be destroyed.
