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 flow co-currently.

In Falling Film evaporators, juice usually enters from the top. It is evenly distributed into the heating tubes. Thin film enters the heating tube and it flows downwards at boiling temperature. In the process, it is partially evaporated. Steam enters in the jacket through slots in calandria. Juice and vapor both flows downward in a parallel flow.
