ABSTRACT:
A method of processing fermented liquid comprising
(a) feeding said fermented liquid into a vacuum vaporizer, (b) heating the feed in said vaporizer to separate it into a vapor and a concentrated liquid fraction, (c) recycling said vapor to said vaporizer by compression so as to achieve heat-exchange with said feed therein thereby generating a new vapor and a condensate fraction; said condensate being discharged as a distillate, (d) supplying the remaining compressed vapor to a multistage distilling column, (e) separating said compressed vapor into two fractions, one with a higher boiling point than the other, within said distilling column, (f) condensing said distillate with the lower boiling point to yield an alcohol-rich distillate, and (g) discharging said fraction with the higher boiling point as a bottom residue, and a processor therefor, thereby discharging to the outside the low COD-liquid alone and recovering useful substances such as drinkable alcohol, livestocks feed and antibiotic substances.
