It is known that during brewing process, raw beer is being concentrated to increase the alcohol % by evaporation. In this process, vertical shell and tube heat exchangers (also known as calandria) are used before the evaporator to maintain desired temperature.

The typical arrangement of this heat exchanger worldwide is as per the following: Steam on the shell side and Beer on the tube side.

This is a very efficient process to achieve concentrated beer. However, depending on the design and process conditions, the heat exchangers of the evaporators are prone to fouling and hence are not able to achieve required evaporation rate which in turn causes high energy and production loss.
