Lab Scale Falling Film Evaporator For Ethanol Recovery
The FFE-250 falling film evaporator include body,thermal conductivity oil furnace, alcohol tank and accessories. The FFE falling film evaporator is used in CBD extraction to recover the ethanol.It is suitable for evaporation and concentration of all kinds of materials, especially for materials that are not easy to scale. Easy to evaporate or have strong heat sensitivity. Our FFE falling film evaporator maintains a high evaporation rate,which significantly increases the throughput of crude oil production. The Alcohol tank is made of S304/S316 Stainless steel,which has good corrosion resistance and meets the requirements of GMP.
1. Feeding port with filtration system, which can do primary filtration when feeding sample.
2. Explosion proof control box. One button starts and stop. With lamp light alarm for running and fault.
3. High condensation efficiency heat exchanger, improve heat transfer efficiency.
4. Flow glass sight and flow meter, can observe the sample process condition at any time.
5. Explosion proof circulating pump and water circulating vacuum pump are both covered by stainless steel, which is more safety and nice shape.
6. Transfer tank connect with cryogenic chiller for ethanol recovery. Including liquid level gauge and filter, which can see the collecting liquid level and do filtration again before recovery.
FFE-250 falling film evaporator is an industrial device to concentrate solutions, especially with heat sensitive components and recover solvents, like ethanol, hexane, heptane, etc. The fluid will create a film along the tube walls, progressing downwards (falling) - hence the name. It is specifically suited to process the products with a low viscosity and a low tendency for fouling.
In general the evaporation takes place inside the vertical tubes, which is called shell-and-tube heat exchanger, crowned by a proprietary liquid distribution device. The fluid distributor is designed carefully in order to ensures an efficient and uniform distribution of the liquid to all the tubes along which the product flows as a continuous film falls, driven by gravity.
The whole solvent recovery system not only includes falling film evaporator, but also equips circulation heater (steam generator as an option), water cooling tower, circulation chiller, vacuum pump and all accessories.
1. 90% - 95% single pass solvent recovery efficiency.
