Principle and characteristics of square vacuum drying oven

Working principle: the so-called vacuum drying is to heat and dry the dried materials under vacuum conditions If the vacuum pump is used for air and humidity extraction, the drying speed is accelerated Note: if the condenser is used, the solvent in the material can be recovered through the condenser; if SK series water ring vacuum pump is used, the condenser can be avoided to save energy investment Product features: the boiling point of the material solution is reduced under vacuum, so that the heat transfer driving force of the evaporator is increased, so the heat transfer area of the evaporator can be saved for a certain amount of heat transfer The heat source of evaporation operation can be low-pressure steam or heating steam The evaporator has less heat loss Before drying, it can be disinfected, and there is no impurity mixed in the drying process, meeting GMP requirements Square and round vacuum dryers belong to static vacuum dryers, so the shape of dried materials will not be damaged.
