Falling Film Evaporator
Falling Film Evaporator Operation
Falling Film Evaporators offer distinct operating advantages in the concentration of many materials, such as certain food products, fruit juices, pharmaceuticals and similar materials, which are particularly suited to evaporation in this type of equipment.

Our Falling Film Evaporators are unique in that they utilize novel operating principle from other types. The dilute liquid is fed to the top of the tubes, flows downward as evaporation occurs.

Uniform distribution of the liquid to the tubes is assured by an exclusive feature which controls the flow of the liquid to the top of the vertical heating tubes. The liquid flows over the edge of the tubes and runs down the inside surface in a thin, uniform film. The vapor travels down the tubes in the same direction as the liquid, gaining in velocity by the addition of more vapor as the mixture descends, resulting in high velocity for both the liquid and vapor.

Evaporation, Distillation & Separation
Evaporator is the descriptive name generally given to process equipment used to remove liquid by vaporization. The feed material may be a single liquid, liquid mixture, solutions or slurries, or any combination of these. Heat applied through some form or heat transfer surface is used to produce the vaporization. The concentrated product, as discharged, is still in fluid, pump-able form.

Distillation is the descriptive name generally given to process equipment used to separate a liquid mixture into separate components via vaporization and condensation. Buflovak designs systems using distillation in applications such as solvent recovery, product purification, solvent drying, VOC steam stripping, alcohol recovery, purification, and others. Our designs are determined through our years of engineering experience, process simulation and pilot testing.
