A Falling Film Evaporator FFE is a vertical shell and tube heat exchanger with a vapor liquid separator mounted at the bottomThe 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 filmAs the film gets heated the vapors generated flow cocurrently.
Falling film evaporators Vertical shellandtube heat exchanger with integrated wraparound monobloctype or laterally arranged separator Functional principle The liquid to be concentrated is fed to the top of the heating tubes and distributed so that it flows down as a thin film on the inside of the tube walls.
Falling Film Technology Falling Film Technology Efficient and ressourcesaving Falling film evaporators are the optimal equipment for evaporationThey are particularly suitable for gentle evaporation and evaporation of temperaturesensitive media.
Feb 22 2019nbsp018332The innovative FFE Series falling film evaporator is ideal for botanical oil separation and ethanol alcohol recovery from your extracted biomass tinctureThe system maintains a high evaporation rate which significantly increases the throughput of crude oil production eliminating the need for multiple large rotary evaporator systems.
Here’s what you need to know about the unsurpassed efficiency of falling film evaporator technology available in many YORK174 chillers.
Hongfei Zheng in Solar Energy Desalination Technology 20177 Falling Film Evaporation of Water Under Constant Pressure75 shows a singleeffect vertical plate falling film evaporator and condensed vertical plate falling film type solar still working principle 27It consists of solar collectors vertical plate falling film.
Nov 07 2018nbsp018332The falling film evaporators have following advantages over flooded evaporators Compact design due to improved heat transferImproved wettability provides uniform heat transfer properties across the tubesLess charge requirement two to three times the evaporation rate.
Our falling film evaporator is specifically suited to process your products with a low viscosity and a low tendency for foulingIt consists of a tube bundle crowned by a proprietary liquid distribution device that ensures an efficient and uniform distribution of the liquid to all the tubesYour product flows as a continuous film along the.
Our falling film evaporators are comercialized under the ENVIDEST MVR FF series of equipment with flow rates up to 2500 Lh per modular unitDifferent models are available depending on their capacity Envidest MVR FF 302500 from 30 Lh to 2500 LhThe equipment has vertical type boilers built in AISI 316L with an integrated centrifugal.

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 liquid film moves down the tubes by gravity forceHeat applied through the tube wall effects boilingoff the light fraction from the filmThe construction of the falling film evaporator is different than the rising film its tube length varies from 10 to 12 meterIn this evaporator the heating unit consists of steam.
