Continuous Feed System with Falling Film Process
In "Cold Ethanol"
Ethanol is cooled down to -40C.In Extraction Vessel
Extraction Vessel is filled with a mixture of ethanol and biomass.Mixer
Mixer is turned on to agitate the slurry.In Extraction Vessel
Slurry is released from Extraction Vessel at a controlled rate, while new ethanol and biomass are being fed in at the same rate.In Centrifuge
Biomass is strained from the slurry.In Lenticular Filter
No need for winterization when extracting at -40C, but the extract laden ethanol is put through carbon filters to remove any residual chlorophyll.In Falling Film
Solution is then heated and run through the falling film for solvent recovery under gentle heat and deep vacuum. As solution runs down the falling film, ethanol is evaporated out.In Distillate Receiver
Ethanol vapors are pulled to the cold condensers, and collected in the distillate receiver as liquid ethanol.Under Falling Film
As the ethanol is removed from solution, extract collects under the falling film.- 1 – In "Cold Ethanol"
