Evaporation Technology

The liquid to be concentrated is fed to the top of the heating tubes and distributed so that it flows down as a thin film on the inside of the tube walls. The liquid film begins to boil due to the external heating of the tubes and is thus partially evaporated. The downward flow, initially caused by gravity, is enhanced by
