What is Falling Film Evaporator?
A falling film evaporator is an industrial device specially used for heat-sensitive component solutions. It is a special type of heat exchanger. In simple words, falling film evaporators is a device used in industries for evaporation and concentration. It is used for the evaporation and concentration of water, organic solvents, and solutions in the pharmaceutical, chemical, food, light industries, and other industries. A falling film evaporator is a collection of an evaporator, a separator, a preheater, a condenser, and a condensate tank.
The falling film evaporator is generally made of 4-8m of tubes confined in steam jackets. It is important to divide the solution in an orderly manner while using a fling film evaporator.
Benefits of Falling Film Evaporators
The benefits that the falling film evaporators provide depend on the kinds of work done by a chiller evaporator. The evaporator is where a liquid evaporates in the form of a gas. The major benefits a falling film evaporator provides are:
The transfer of the heat collected is comparatively larger due to the material used in the heat exchange tube is in the film state that has a faster flow rate.
The heat-sensitive materials’ chemical property won’t get affected due to the short duration of the raw material in the heat exchange tube.
The material used on the pipe side is approximately in the ambient temperature without pressure drop that helps in energy saving.
As the pipe material in falling film evaporators flows downwards along the inner wall on its own hence the difference of low temperature can be selected.
The boiling of the raw materials does not affect the surface of the heat exchange as it transfers the building materials when the material is heated.
Falling film evaporators are highly responsive to changing parameters such as energy supply, vacuum, feed rate, concentrations, etc. When supplied with a well-designed automatic control system they can produce a consistent concentrated product.
