Description
Bei der Lüftung von gärender Würze oder Maische bei der Hefefabrikation ist die Anwendung von zwei oder mehreren einander ergänzenden Belüftungen bekannt.For ventilation of fermenting wort or mash in yeast production it is known to use two or more complementary vents.
Es ist weiter bekannt, Steigrohre in die Gärbottiche einzubauen, die Maische in diesen Steigrohren durch Belüftung hochzuheben und die Maische dann überlaufend den im Bottich gebildeten Schaum zerstören zu lassen.It is also known to build risers into the fermentation vats that Lifting the mash in these risers by aeration and then overflowing the mash to destroy the foam that has formed in the vat.
Das vorliegende Verfahren beruht auf einer besonderen Kombination in Anlehnung an diese bekannten Maßnahmen und besteht darin, daß einerseits durch am Boden des Gärbottichs angeordnete Belüftungskörper eine Belüftung der Maische vom Boden aus durchgeführt wird und andererseits die Maische durch eine zusätzliche Belüftung in an sich bekannter Weise in einem oder mehreren Rohren, die in einem gewissen Abstand oberhalb des Bottichbodens angeordnet sind und oberhalb der Schaumbildungszone enden, über die letztere hochgehoben wird, auf die entstehenden Schaummassen fällt und diese zerstört.The present method is based on a special combination based on these known measures and consists in that on the one hand by Aeration bodies arranged at the bottom of the fermentation vat provide aeration for the mash is carried out from the ground and on the other hand the mash is carried out by an additional Ventilation in a manner known per se in one or more pipes in one a certain distance are arranged above the bottom of the tub and above the foam formation zone ends, over which the latter is lifted, falls onto the resulting foam masses and destroys them.
Es wird dadurch erreicht, daß die Belüftung normal und unabhängig von der gewollten Schaumzerstörung stattfindet und daß die Luftmenge, die dazu dient, die Maische in den Steigrohren hochzutreiben, nur eine zusätzliche Belüftung darstellt.It is achieved by making the ventilation normal and independent the desired foam destruction takes place and that the amount of air that is used to to force the mash up in the riser pipes is only an additional ventilation.
Das Verfahren wird an Hand der Abbildung, die einen Gärbottich mit einer Einrichtung zur Durchführung des erfindungsgemäßen Verfahrens darstellt, näher erläutert.The procedure is based on the illustration that has a fermentation vat represents a device for performing the method according to the invention, in more detail explained.
Die Maische wird am Boden des Bottichs belüftet. Die Füllhöhe ist hi, die Steighöhe 1a2. In einer gewissen Höhe über dem Boden des Gärbottichs sind zusätzliche Belüftungskörper d angeordnet; die belüftete Maische steigt in dem Rohr r hoch und fällt über den Rand des Rohres in den Gärbottich zurück. Die Menge der in dem Rohr r hochgehobenen Maische kann durch die Stärke der vermittels des Ventils k regelbare@nrLuftzufuhr verändert werden. Mit der Menge und der gewählten Fallhöhe wächst die Fallenergie der aus dem Rohr tretenden Maische, welche den entstandenen Schaum kontinuierlich ohne Anwendung von Gärfett zerstört. Ein weiterer Vorteil des Verfahrens ergibt sich aus der im Bottich entstehenden lebhaften Zirkulation der Maische und der damit verbundenen besseren Ausnutzung der zugeführten Luftmengen für die Veratmung des Sauerstoffs der Luft durch die Hefezellen, der schnellen Verteilung der zugeführten Nährlösung und der Erhöhung des für die Wärmeabfuhr. Diese Zirkulation kann bei Bottichen mit größeren Grundflächen eine zusätzliche waagerechte Richtung erhalten, wenn man die Bodenbelüftung in Felder beliebiger Größe einteilt, von denen ein Feld stärker belüftet wird als das Nachbarfeld, was z. B. dadurch geschehen kann, daß das Nachbarfeld weniger Belüftungskörper, bezogen auf seine Grundfläche, erhält.The mash is aerated at the bottom of the vat. The filling level is hi, the climbing height 1a2. Are at a certain height above the bottom of the fermentation vat additional ventilation body d arranged; the aerated mash rises in the pipe r high and falls back over the edge of the pipe into the fermentation vat. The amount of in the tube r raised mash can be controlled by the strength of the valve k adjustable @ no air supply can be changed. With the amount and the chosen height of fall the falling energy of the mash emerging from the pipe and the resulting mash increases Foam continuously destroyed without the use of fermentation fat. Another advantage of the process results from the lively circulation created in the vat the mash and the associated better utilization of the air quantities supplied for the inhalation of the oxygen in the air by the yeast cells, the rapid distribution the supplied nutrient solution and the increase in heat dissipation. This circulation can use an additional horizontal direction for tubs with a larger base obtained by dividing the soil aeration into fields of any size, of which a field is ventilated more than the neighboring field, which z. B. happen thereby it can be that the neighboring field has fewer aeration bodies, based on its base area, receives.
