Film evaporators has characteristics of high heat transfer efficiency, high evaporation speed and short material stay time, so is especially suitable for the evaporation of the thermal sensitive material. Classification of Film Evaporator According to the film reasons and flow direction, can be divided into rising membrane evaporator, falling film evaporator, scraping membrane evaporator three types. Structure of Film Evaporator Film evaporators unit is composed by the evaporator, liquid-gas separator, preheater three parts and a simple separator. Evaporator is rising membrane type heat exchanger tube. Usages of Film Evaporator It is used in pharmaceutical, food, chemical industry for concentration of dilute solution. Characteristics of Film Evaporator The evaporator has characteristics of great production capacity, high thermal efficiency, short material heating time etc. All the parts contacted with material made of stainless steel with good corrosion resistance, is accord with drug health requirements.
