PURPOSE:To improve the yield of alcohol from the sugar used as a raw material, by using a fermentor furnished with a means for separating the carrier of bacteria from the fermented liquid, and carrying out the alcoholic fermentation using bacteria having alcoholic fermentation capability and attached to the carrier and agglomerating yeasts. CONSTITUTION:The fermentor is composed of the fermentation tank 13 and the precipitation tank 14. For example, blackstrap molasses diluted to 5 times volume is supplied to the fermentation tank 13, and subjected to the alcoholic fermentation by the action of the agglomerating yeasts and the bacteria having alcoholic fermentation capability and attached to a carrier such as pulverized vermiculite, activated charcoal, zeolite, etc. The yield of alcohol can be improved by the combined action of the bacteria and the yeasts. After the fermentation, the liquid is overflowed continuously from the top of the fermentation tank 13 to the precipitation tank 14 to precipitate the carrier, and the supernatant liquid is discharged from the precipitation tank. The precipitated carried is returned to the fermentation tank 13 with a pump, and reused. |
