Abstract

An improved fermentation process is described for producing alcohol which includes the combination of vacuum fermentation and vacuum distillation. Preferably, the vacuum distillation is carried out in two phases, one a fermentor proper operated at atmospheric pressure and a flash phase operated at reduced pressure with recycle of fermentation brew having a reduced alcohol content to the fermentor, using vapor recompression heating of the flash-pot recycle stream to heat the flash-pot or the distillation step, and using water load balancing (i.e., the molar ratio of water in the fermentor feed is the same as the molar ratio of water in the distillation overhead).

Vacuferm process: a new approach to fermentation alcohol

Journal Article Ramalingham, A; Finn, R - Biotechnol. Bioeng.; (United States)

A Vacuferm process is envisaged in which full-strength clarified molasses is fed continuously to the fermentor - still along with a recycled cell cream of aerobically grown yeast. The yeast would then need no added sterols or oleic acid. Since it is probably impractical to use an expensive vacuum fermentor to remove the last traces of sugar and alcohol from spent beer, the latter could be aerated at atmosphere pressure to provide additional yeast growth. After centrifuging, a portion of the aerated yeast cream could be returned to the fermentor as continuous inocolum; the remainder would be dried for salemore »« less

Medium-sized ideal reactor for continuous alcohol fermentation using immobilized microorganism

Journal Article Skachova, H; Gottvaldova, M; Kucera, J; ... - Biotechnol. Bioeng.; (United States)

Recently, alcohol fermentation has gained considerable attention with the aim of lowering its production cost in the production processes of both fuel ethanol and alcoholic beverages. The over-all cost is a summation of costs of various subsystems such as raw material (sugar, starch, and cellulosic substances) treatment, fermentation process, and alcohol separation from water solutions; lowering the cost of the fermentation process is very important in lowering the total cost. Several new techniques have been developed for economic continuous ethanol production. These include the slow growth of highly flocculent yeasts in a tower fermentor for beer production, use of amore »« less
