Falling Film (FF) Evaporators This evaporator design relies either on tubes or plates as heat transfer surfaces. Liquor is processed on the inside of the s in tubular units but on the outside of the heat transfer surface in plate designs. FF evaporators consist of a liquor sump from which a defined volume of liquor is continuously recirculated to

Falling Film Evaporator Design. Shell tube evaporators, on the other hand, do not use a wiper blade to obtain a thin film. A falling film evaporator is comprised of a bundle of parallel tubes that are welded together at each end. The tube bundle is encased in a jacket that allows heat transfer fluid to be pumped across the outside of the tubes.

In falling film evaporators, the liquid product usually enters the evaporator at the head of the evaporator. In the head, the product is evenly distributed into the heating tubes. 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.
