Our evaporator is widely acclaimed by the clients for its superb attributes like consistent performance, high operation efficiency and longer service life. We offer this Falling Film Evaporator in various sizes and specifications so as to meet the varied industrial demands.
Excellent heat transfer coefficients.
Low temperature operation
Optimum heat transfer area
Self cleaning action from salting
Scaling and fouling
Preheating of liquid is done to the boiling temperature for concentrating it. In the heating tube, tiny films enter through a distributor connected at the top of evaporator. Then it moves downwards at the boiling temperature that causes it to evaporate partially.
Falling Film Evaporator works on the principle of liquid-spreading into every tube, hence creating a tiny film all over the tube's area
Ideal for formulating liquors whose specific heat transfer rate is high
Also suitable for fluids with low viscosity, less fouling and also for non crystalline solutions.
Its process is controlled via convection and / or conduction through the film that are two processes for heat transfer
Effects of thermal degradation can be easily minimized using short product contact time
Because of the heat flux and low temperature of tube wall, fouling can be reduced
Renders highly efficient performance to allow designs with multiple effects
Ideal choice for the areas that use heat sensitive products
Bulletined below are the points that describe detailed working of the aforementioned evaporator:
Top of the exchanger is the place from where the liquid enters that needs to be boiled
Tubes need to be equally wet and this is ensured by the internal distributor
A film of liquid is placed along the tube sides for avoiding the tubes from flooding
While the liquid is passed through the tubes, it is boiled
Vapor is collected at the bottom of exchanger while the liquid is flushed out
In most of the cases, this collected vapor find usage for heating the evaporator
