ABSTRACT:
Alcohol is produced by continuous fermentation process in which must is fermented in a vat. Fresh must is introduced into the vat and fermented must is withdrawn from the vat. Fermented must withdrawn from the vat is pumped from the vat in a pumping column of a circuit extending above the vat in which carbon dioxide exerts mammoth pumping action. A back pressure is maintained and adjusted in an upper portion of the vat which is connected with the pumping column for concentrating carbon dioxide in the vat and for controlling the flow rate of the mammoth pumping column and the circulation speed of the must in the circuit. The pumping column is connected with a pipe which is connected to a lower portion of the vat which completes the circuit and which is disposed for effecting a turbulent flow of the carbon dioxide depleted must and for returning recycled must to the vat. Carbon dioxide is separated from the must in the pumping column and exerts the mammoth pumping action. A mixture of oxygen and inert gas is introduced into the turbulent flow of must in an upper portion of the return pipe.
