ABSTRACT:
A fermentation apparatus for converting agricultural raw materials into a fermented liquor containing about 10 weight percent ethanol comprising a fermentation chamber, a separation chamber, a conduit for transporting mash through the fermentation chamber and the separation chamber, and at least one pump for circulating an aqueous yeast-containing solution in the fermentation chamber into the conduit for contact with the mash to convert the simple sugars in the mash to ethanol. A gas separator is positioned within the separation chamber to remove the carbon dioxide generated by the fermentation of the simple sugars in the mash such that the carbon dioxide does not enter and agitate the aqueous ethanol mixture in the separation chamber.
