Falling Film Evaporator (FFE)

Falling Film Evaporator (FFE)

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 ...

A falling film evaporator is a type of heat exchanger that uses a shell and tube design to evaporate heat-sensitive liquids. The feed is pumped into the evaporator from the top. It’s then uniformly dispersed throughout the heating tubes of the device. While partially evaporated, the liquid flows through tubes, forming a thin layer on the tube ...

A Falling film evaporator is an industrial device to concentrate solutions, especially with heat-sensitive components. The evaporator is a special type of heat exchanger.In Falling film evaporators, the liquid film falls by gravity in the vertical evaporation surface that is inside the tube or plate, while the heat is transferred through the walls by the condensing steam.
