A Falling Film Evaporator (FFE) is a combination of vertical shell and tube heat exchanger and vapor- liquid separator mounted at bottom. The feed is given at top of shell & tube type heat exchanger having distributor. The liquid falling on distributor get distributed in such a way that it flow down as a thin film on inside surface of the tube.
Our falling film evaporator is specifically suited to process your products with a low viscosity and a low tendency for fouling. It 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 tubes. Your product flows as a continuous film along the ...
Jul 10, 2019 · The falling film evaporator can evaporate substances that are higher-concentration, higher-viscosity, and heat-sensitive substances. The working system of the falling film evaporator is different from the rising film evaporator’s working system. During the working of the falling film evaporator, liquid goes from the top to the bottom.
First of all, a falling film evaporator is a crucial tool to have if you need to reduce water from food samples. This is because this tool can remove from 78% to 87% of the moisture from the food. Moreover, it can do this while allowing for the biological and …
Jul 23, 2019 · We developed falling film heat transfer coefficient (FFHTC) correlation for saline water evaporation from 280 to 305 K saturation temperatures. We also demonstrated the effect of salt concentration on heat transfer and LMTD. This will help to design efficient falling film evaporators for processes industries.
Dec 21, 2013 · Tip 4 – Consider a Prewash. Once the CIP solution is in the system very often the evaporator is brought into a circulation mode. Make sure that there is not too much fouling at the first quarter of the CIP run. This fouling, now on the loose in your system, will spray dirty CIP agent on the internal walls of the evaporator.
Jul 17, 2015 · Falling film evaporator (of dreams), or WFE not needed when married. WIFE - uses laser eyes to totally evaporate all dreams from taking place. Some days she is actually quite nasty, others she is intolerably mean as hell. I think she has a tumor the size of herself. She keeps trying to have me removed.
Pratima Bajpai, in Biermann's Handbook of Pulp and Paper (Third Edition), 2018. Falling Film Evaporators.
