ABSTRACT:
A fermentation apparatus for the production of alcohol provides for continuous circulation of must through the apparatus. A pumping column is connected to a top of a fermentation vat via a back pressure valve and extends above the vat for pumping fermented must transferred from the vat via the back pressure valve. A must degassing device is connected to the pumping column at a position above the column. A must return pipe is connected to the degassing device and to a bottom portion of the vat for conveying must in a turbulent flow to the vat and to a hydraulic stirring device positioned in the bottom portion of the vat for stirring must in the vat. A gas injection device is connected to an upper portion of the return pipe for introducing gas into the flow of must in the pipe. Alcohol may be collected by a decanter connected to the return pipe and/or by a device for heating the must in the pumping column.
