 des Sauerstoffüberträgers ist os belanglos, ob die Neutralisierung der Lauge gleichzeitig, vor oder nach der Behandlung mit dem Sauerstoffüborträger   vorgenommen   wird. Das gebrachte Neutralisierungslllittel arbeitet jedoch mit dem Sauerstoffüberträger   insofern   zusammen, dass es Sauren und   Saureverbindungen,   die sich in der Lauge durch die bei der Lüftung eintretende Oxydation bilden   oder frei werden und weiche   vor der Gärung der Lauge unschädlich gemacht worden müssen, neutralisiert. 



   Nachdem die erste Behandlung beendigt ist, wird die Lauge eventuell nach vorher-

 of the oxygen carrier, it is irrelevant whether the alkaline solution is neutralized at the same time, before or after the treatment with the oxygen carrier. However, the neutralizing agent used works together with the oxygen carrier to the extent that it neutralizes acids and acid compounds that are formed in the liquor by the oxidation occurring during ventilation and which must be rendered harmless before the liquor is fermented.



   After the first treatment is finished, the lye may be used after

 mechanical dissolution of oxygen in the liquor takes place. After this renewed ventilation, the liquor is ready for fermentation and can be tapped directly from the fermentation vats on the roof.
