ABSTRACT:
A method and apparatus particularly suitable for the production of alcohol from fermentable substances such as grain. In this method, mash cooking, fermentation, and boiling are carried out sequentially in a single vessel. Boiling produces a first vapor rich in alcohol which is partially condensed to form a liquid condensate and a second vapor which is further enriched in alcohol. The liquid condensate is returned to the vessel and an alcohol product is recovered from the second vapor, preferably without the addition of external heat. Alcohol recovery is effected by passing the second vapor to a second vessel. Vapor from the second vessel is partially condensed to form a third vapor which is still further enriched in alcohol and a liquid condensate which is returned to the second vessel where it is contacted by the second vapor introduced thereto. The apparatus comprises a single vessel for effecting the heating, boiling and fermenting steps and is provided with heating and cooling means for establishing appropriate temperatures for these steps. Partial condensation is achieved in packed columns having cooling means in the upper regions thereof.
