A falling film evaporator consists of a vertical tubular heat exchanger in which a thin film of liquid is continuously fed down the inner wall of the tube. The heat exchanger is typically placed in a vacuum chamber to enhance heat transfer.

Let’s take a look at some special features and applications of falling film evaporators.

Falling film evaporators are very efficient and can evaporate large quantities of liquid in a short amount of time. Additionally, these evaporators can operate at a lower temperature than other types of evaporators, which makes them ideal for heat-sensitive products.

A falling film evaporator is used to heat and condition liquid products using steam. The heat transfer surface is more extensive. It has increased efficiency

The falling film evaporator has excellent corrosion resistance. It has a low temperature because it is suitable for a variety of heat-sensitive materials.
