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 evaporated.
A Falling Film Evaporator (FFE) is a vertical shell and tube heat exchanger with a vapor- liquid separator mounted at the bottom. The liquid to be concentrated is fed at the top of the heated tubes and distributed in such a way that it flows down on the inside surface of the tubes as a thin film. As the film gets heated, the vapors generated flow co-currently.
