Description

Verfahren zur Feinstbelüftung von Diaphragmen-Gärbottichen Es sind Verfahren zur Belüftung von Flüs- sigkeiten, insbesondere von Gärflüssigkeiten, bekannt, welche bezwecken, die Luft in Form kleinerer Bläschen der Gärflüssigkeit zuzu- führen. Doch haben diese Belüftungsverfahren ebenso wie die bisher in der Gärungsindustrie üblichen Eiorichtungen keineswegs das End- ziel, d. h. die stä:idige Derührung der Hefe- zellen mit dem L uftsauerstoff, welche für ihre maximale Vermehrung notwendig ist, er- reicht. Die Belüftung durch poröse Ton- böden bedeutete wohl gegenüber den üblichen.

However, these have ventilation methods as has been the case so far in the fermentation industry usual egg directions by no means the end goal, i.e. the constant flow of the yeast cells with the oxygen in the air, which are necessary for their maximum propagation is necessary, enough. The ventilation through porous clay Boden probably meant opposite the usual.

If one wanted to take into account the knowledge that only constant contact with air would satisfy the yeast's oxygen requirements, and indeed with strict attention to economic means, then similar but better ways of achieving this had to be sought.

Dieses Ziel wird erreicht durch Verwendung von Platten aus Diaphragmenmassen, wie sie für elektrolytische Zwecke benutzt werden. Diese Diaphragmenmassen haben eine Porengröße von o,16 bis I #z. Sie sind daher undurchlässig gegen Zellen und Bakterien und im Bereiche der praktischen Notwendigkeit auch undurchlässig gegen Flüssigkeiten. Dagegen lassen sie bei entsprechendem Druck Luft und Gase in Form von feinsten Bläschen hindurch, deren Durchmesser in die Größenordnung der Poren fällt. Infolge der außerordentlich geringen Aufsteigegeschwindigkeit dieser kleinsten Luftbläschen wird die für einen bestimmten ständigen Luftinhalt der Maische notwendige Luftzufuhr bei gleichzeitiger Deckung des Sauerstoftbedarfes der Hefe ein Minimum, und es sinkt dementsprechend der für die Belüftung benötigte Kraftbedarf. Bei der jetzt üblichen Belüftung durch Strahlrohre werden für einen Gärbottich von 1 oo cbln Flüssigkeitsinhalt bei 1 o alo Luftinhalt und bei einer Blasengröße von 5 bis 6 mm stündlich 62 PS verbraucht, bei o,1 mm Blasendurchmesser dagegen nur 1,2 PS. Trotz dieses geringen Kraftbedarfs ist in letzterem Falle die Zahl der die Flüssigkeit durchsetzenden Luftblasen etwa 1 ooinal größer. Bei. einer weiteren Verkleinerung der Blasendurchmesser fällt bei gleichem Luftinhalt der Kraftbedarf ebenfalls weiter, nährend die Anzahl der Blasen steigt. Beispielsweise befinden sich in a o ccm Flüssigkeit mit i o % Luftinhalt 1,25 Billionen Luftbläschen von i &. Durchmesser.This goal is achieved by using plates made of diaphragm masses such as those used for electrolytic purposes. These diaphragm masses have a pore size of 0.16 to I #z. They are therefore impermeable to cells and bacteria and in the realm of practical necessity also impermeable to liquids. On the other hand, if the pressure is appropriate, they allow air and gases to pass through in the form of the finest bubbles, the diameter of which falls within the range of the pores. As a result of the extremely low ascent speed of these smallest air bubbles, the air supply necessary for a certain constant air content of the mash is a minimum while at the same time covering the oxygen requirements of the yeast, and the power required for aeration is reduced accordingly. With the now usual ventilation by jet pipes, a fermentation vat of 1 oo cbln of liquid content with 1 o alo air content and a bubble size of 5 to 6 mm consumes 62 hp per hour, with a bubble diameter of 0.1 mm, on the other hand, only 1.2 hp. Despite this low power requirement, in the latter case the number of air bubbles penetrating the liquid is about 1 ooinal greater. At. If the bubble diameter is further reduced, the power requirement continues to fall with the same air content, while the number of bubbles increases. For example, ao ccm of liquid with 10% air content contains 1.25 trillion air bubbles of i &. Diameter.

Um ein für den Belüftungseffekt schädliches Absetzen von Sinkstoffen ans der Maische auf die Böden der Diaphragmen-Gärbottiche bei dieser feinsten und daher außerordentlich ruhigen Belüftung zu verhindern, muß die Maische bewegt werden. Die Bewegung durch eines der üblichen Rührwerke würde jedoch eine Vereinigung der Bläschen zu größeren Blasen und damit gewissermaßen eine Entlüftung der Maische herbeiführen. Zur Vermeidung dieses Nachteils wird die Maische zweckmäßig durch eine Umlaufvorrichtung in Bewegung gesetzt, die sich aufierhalb des eigentlichen Bottiches befindet und gegebenenfalls für die Abfuhr der Gärungswärme mit einem Röhrenkühler verbunden sein kann. Im Bottich selbst wird die Stromführung durch Trennung desselben in einzelne Abteilungen gewährleistet. Die Strömungsgeschwindigkeit ist regulierbar- und wird zweckmäßig so eingestellt, daß die Luftbläschen nicht senkrecht, sondern schräg, etwa unter ¢5° aufsteigen.A settling of suspended matter that is harmful to the ventilation effect ans the mash on the bottoms of the diaphragm fermentation vats with this finest and therefore, to prevent extremely quiet aeration, the mash must be agitated. However, the movement through one of the usual agitators would be a union of the Bubbles to larger bubbles and thus to a certain extent a deaeration of the mash bring about. To avoid this disadvantage, the mash is expediently through a circulating device set in motion, which is located outside of the actual Vats are located and, if necessary, for the removal of the fermentation heat with a Tubular cooler can be connected. The current is carried through in the vat itself Separation of the same into individual departments guaranteed. The flow rate is adjustable - and is appropriately adjusted so that the air bubbles do not rise vertically, but at an angle, approximately below ¢ 5 °.
