300 Stainless Steel Falling Film Evaporator, Automation Grade: Automatic

In Falling Film Evaporator, the high velocity feed enters from the top of the evaporator and falls down the tube wall. As the temperature is uneven within the tubes (due to steam), the boiling of feed occurs when it has travelled half way into the tubes. As the feed moves further downwards, its temperature decreases due to evaporation and it forms vapours. These vapours form small bubbles which aggregate to form large bubbles and travel downwards. This mixture of liquid and vapour gets separated at the bottom. The separated liquid gets concentrated during falling and is collected as product from the bottom.
