Principles

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.

Note: if use condensate, the solvent in raw material can be recovered. If use SK series water ring vacuum pump sets, condensate can not be used and the investment could be saved.

Features 

â—ŽUnder 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 be

saved;

â—ŽThe heat source for operation of evaporation may be low pressure steam or surplus heat steam;

â—ŽThe heat loss of evaporator is less;

â—ŽBefore drying, the treatment of disinfection may be carried out. During the period of drying, there is no impurity material mixing. It is in conformity with the requirement of GMP;

â—ŽIt belongs to static drier. So the shape of raw material to be dried can not be destroyed.

Applications

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 and electronic industries.
