Introduction

The liquid to be concentrated is fed at the top of the heated tubes and distributed in such a way that it flows down on the inside surface of the tubes as a thin film. As the film gets heated, the vapors generated flow co-currently. The drag of vapors increases the turbulence and improves heat transfer performance. The vapor and balance liquid are separated in the vapor-liquid separator.

Falling Film Evaporator Features:

Suitable to process highly-concentrated materials with high viscosity.

Suitable for heat sensitive products.

Gentle but high evaporation with a short residence time in the evaporator.

Can operate continuously under reasonable vacuum.

Multiple effect arrangement provides steam economy.

Lower energy consumption & lower operation costs.

Falling Film Evaporation Unit Application :

It’s widely used in the evaporation and concentration of water or organic solvents in industries like pharmaceuticals, food, chemical engineering, light industry, etc. It’s also widely used to treat waste liquids in the above-mentioned industries.
