Abstract
A method for the submersed, automatically controlled production of fermentation vinegar from ethanol is conducted in two stages. The installation for accomplishing the method includes one or more pre-fermenters and a product fermenter, in connection with which each pre-fermenter exhibits a volume 1.7 to 3.5 times that of the product fermenter. The terminus of the fermentation is reached in the product fermenter when the dissolved oxygen, indicated by means of an oxygen electrode, rises, at which point the product valve is opened. The product fermenter is evacuated when no more alcohol remainder is present. In the final step the alcohol is therefore completely utilized.
