Process for the manufacture of ethyl alcohol from citrus molasses

摘要

The invention relates to a process for the production of ethyl alcohol from citrus molasses fermentation in which improved yields of ethyl alcohol are obtained by preliminarily removing fermentation inhibiting agents, specifically oils, from the fermenter charge. The process may be carried out in batch or by continuous operation. The alcohol formed in the fermentation step is distilled off at about 190 DEG proof and the latter may then be dehydrated in a molecular sieve column to produce a product substantially free of water. Also a novel oil stripper is presented in order that the oils may be effectively and economically removed prior to fermentation.
