Our Falling Film Evaporator (FFE) offers thinner & faster moving film that gives rise to shorter product contact time with maximum heat transfer. Special Features Highly suitable for heat sensitive products Minimizes thermal degradation due to short product contact time Fouling is minimized due to low tube wall temperature and heat flux
Working Principle of Falling Film Evaporator The liquid to be concentrated is supplied to the top of the heating tubes and distributed in such a way as to flow down on the inside of the tube walls. The liquid film starts to boil due to the external heating of the heating tubes and is partially evaporated as a result.
The low boilers are partially evaporated from the descending film, flow with the concentrate into the sump of the falling film evaporator and are conducted as steam to the external condenser for condensation. As a result, the distillate flows out of the condenser. Meanwhile, the non-evaporated liquid flows along the falling film evaporator tubes, is continuously concentrated …
