Evaporator Types FALLING FILM EVAPORATORS Design Vertical shellandtube heat exchanger, with laterally or con centrically arranged centrifugal separator. Operation The liquid to be concentrated is supplied to the top of the heating tubes and distributed in such a way as to flow down the inside of the tube walls as a thin film.

Applications for Falling Film Evaporators

Falling film evaporators are used extensively in chemical process industry, food and paper industry. Due to the absence of static static head effect caused by liquid column as in other types of evaporators, evaporation can take place at very small effective mean temperature differences. The temperature diffference are tipically between 3 - 8C.

Falling Film Tubular Evaporator Thermal Kinetics

Falling film evaporators are vertical shell and tube heat exchangers. Typical TEMA types are BEM, NEN or a combination of the two. The major difference between a typical shell and tube heat exchanger and a falling film evaporator is the liquid distribution at the top of the unit. Liquid entering the top of the unit passes either through a spray ...

Falling film evaporator - WikiMili The Best Wikipedia Reader

Mar 15, 2022 A climbing/falling film plate evaporator is a specialized type of evaporator in which a thin film of liquid is passed over a rising and falling plate to allow the evaporation process to occur. It is an extension of the falling film evaporator, and has application in any field where the liquid to be evaporated cannot withstand extended exposure ...

Spray Engineering Devices

Plate Type Falling Film Evaporator (PTFFE) is efficiently developed for optimizing evaporation of sugar solutions with full accessibility of the heat transfer surfaces. PTFFE has the lowest pressure losses and higher turbulence on liquid side to achieve the highest heat transfer coefficient. Due to very high heat transfer rate of these evaporators, evaporation from a …
