Applications:

Our falling film evaporator (FFE) is a specific type of vertically oriented shell and tube (S&T) heat exchanger that is used to separate two or more substances with different boiling point temperatures.

Working Principle:

In falling film evaporators, the liquid product usually enters the evaporator at the head of the evaporator. ... The liquid enters the heating tube and forms a thin film on the tube wall where it flows downwards at boiling temperature and is partially evaporated. In most cases, steam is used for heating the evaporator.
