Falling Film Evaporator forced film evaporator -Shachi Eng

A falling film evaporator is essentially a shell tube type of heat-exchanger used to evaporate heat sensitive liquids. The feed enters the evaporator through the top of the unit. It is then distributed evenly in the unit’s heating tubes. The liquid flows through tubes and forms a thin film on the walls of the tube while being partially ...
