Falling Film Evaporator Design Our falling film evaporator is the simplest and most commonly used type of film evaporatorThe liquid flows as a thin film on the inside of heated vertical tubes driven by gravityThe resulting vapor normally flows cocurrently with the liquid in the centre of the tubes.
Falling film evaporators are greatly responsive to all sorts of adjustments of the parameters including the energy supply feeding rate vacuum concentrations etcWhen you design an automatic control system with the evaporator they are capable of producing a consistently concentrated product.
Falling film evaporators are vertical shell and tube heat exchangersTypical TEMA types are BEM NEN or a combination of the twoThe major difference between a typical shell and tube heat exchanger and a falling film evaporator is the liquid distribution at the top of the unitLiquid entering the top of the unit passes either through a spray.
Fallingfilm evaporators allow advanced steamsaving concepts to be implemented for sugar production.
In falling film evaporators Wiegand 1971 the feed is introduced at the upper end of long vertical tubes taking care to distribute the liquid as a film over the entire internal surface of the tubes FigThe film moves downward by gravity assisted by vapor drag.

T he falling film evaporator system EFF is used for gentle partial evaporation of liquid mixtures especially when requirements – eLow operating pressures at high evaporation rates – exceed the capabilities of classical evaporatorsThe raw solution is fed into the evaporator from a feed batch vessel or continuously and evenly distributed as a thin film over the surface of the.
The diagram shows a drawing of the Falling Film Evaporator with the required connecting streamsThe Falling Film Evaporator expects 2 inlets Steam In and Weak Liquor inThree outlets must also be connected these are condensate concentrated liquor and evaporated vapour from the liquor.
The Falling Film Evaporator FFE has its own take on the technology incorporating improved features that keep the operator in mindAs a large portion of the tincture processed using a falling film evaporator is coming from a cold ethanol extraction the design takes advantage of the cooling power that is already a sunken cost in the form of the electricity used to generate it.
The Falling Film Evaporator with capacity ranges of up to 150th and relatively small floor space requirement is the most widely used evaporator in the process industryParticularly well suited for temperaturesensitive products liquids containing small quantities of solids and with a low to moderate tendency to form incrustations.
The total heat transfer coefficient of falling film evaporation on the horizontal tube can be divided into two parts film heat transfer coefficient of evaporation outside the tube and film coefficient of condensation inside the tube as shown in Fig.
Working principle of falling film evaporatorsA falling film evaporator is essentially a shell amp tube type of heatexchanger used to evaporate heat sensitive liquidsThe feed enters the evaporator through the top of the unitIt is then distributed evenly in the unit’s heating tubesThe liquid flows through tubes and forms a thin film on.
