Falling Film Evaporators: Principles Applications Alaqua

Falling Film Evaporators: Principles Applications Alaqua

0. 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 ...

Falling Film Evaporation Process

Falling Film Evaporation Process

A Falling Film Evaporator (FFE) is a combination of vertical shell and tube heat exchanger and vapor- liquid separator mounted at bottom. The feed is given at top of shell tube type heat exchanger having distributor. The liquid falling on distributor get distributed in such a way that it flow down as a thin film on inside surface of the tube.

What are the Advantages and Disadvantages of Falling Film Evaporators?

Dec 08, 2021 A falling film evaporator is a machine used to separate two or more substances with different boiling point temperatures. It does this by taking advantage of changes in state at different temperatures and uses heaters and condensers to complete this task. These machines have many applications across a variety of industries, including the cannabis and hemp sector.
