Falling Film Evaporator
Falling Film Evaporator
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.
The falling film principle requires an even distribution of the feed liquid. To achieve this distrubution one or more distribution trays are located in the top head of the evaporator over the complete tube sheet.
Our proven distribution devices make sure that the inner surface of each individual tube is properly wetted.
Heat applied through the tube wall effects boiling-off the light fraction from the film. The picture shows a co-current operating evaporator with vapour and liquid leaving the bottom of the evaporator into the separator vessel.
