unter sehr hohem Druck.under very high pressure.

Es ist bekannt, Wein u. dgl. in großen Gefäßen unter mehr oder weniger hohem Druck, bei dem die Gärungskohlensäure inniger in der Flüssigkeit gebunden wird, zu vergären und die Gärung gegebenenfalls durch Erhöhung oder Erniedrigung des Druckes zu mäßigen oder zu beschleunigen.It is known to store wine and the like in large vessels under more or less high pressure, in which the fermentation carbonic acid is bound more intimately in the liquid to ferment and to moderate fermentation if necessary by increasing or decreasing the pressure or speed up.

Wenn hierbei, wie es bisher der Fall gewesen ist, Gas von außen in den Behälter gelangt oder in ihm Gas frei werden und aus der Flüssigkeit austreten kann, so sammelt sich dieses Gas über der Flüssigkeit an, anstatt innerhalb derselben von organischen Substanzen gebunden zu werden.If, as has been the case up to now, gas enters the container from the outside or gas can be released in it and emerge from the liquid, so collects this gas appears above the liquid, instead of organic substances within it to be bound.

Die Erfindung betrifft ein besonderes Verfahren zur Herstellung von Getränken mittels Gärung unter Druck, das sich von dem erwähnten bekannten dadurch unterscheidet, daß der Gärbehälter ohne irgendwelchen Gasraum vollständig mit der zu vergärenden Flüssigkeit gefüllt wird, so daß die Gärungskohlensäure aus der Flüssigkeit nicht austreten kann, sondern in dieser aufgespeichert und zurückgehalten wird.The invention relates to a special method for the production of beverages by means of Fermentation under pressure, which differs from the known known in that the fermentation tank completely with the liquid to be fermented without any gas space is filled so that the fermentation carbon dioxide cannot escape from the liquid, but is stored in this and held back.

Eine Vorrichtung zur Ausführung dieses Verfahrens ist in der Zeichnung im Vertikalschnitt in beispielsweiser Ausführungsform dar-. gestellt.An apparatus for performing this method is shown in the drawing in vertical section in an exemplary embodiment. posed.

Die gärungsfähige Flüssigkeit wird gleich nach Beginn der Gärung in großen, aus emailliertem Stahl bestehenden Behältern A, die je nach der Art der verwendeten Flüssigkeit einem Druck von 6 bis 40 Atm. Widerstand leisten können, eingeschlossen. Diese zylinderförmigen Behälter A besitzen konische Böden a, aus denen sich absetzende Hefe durch einen Hahn b leicht entfernt werden kann. Den durch die Doppelwand c gebildeten Raum durchfließt eine Kühlflüssigkeit, die bei χ ein- und bei y austritt.Immediately after fermentation begins, the fermentable liquid is placed in large enamelled steel tanks A , which, depending on the type of liquid used, has a pressure of 6 to 40 atm. Can resist, included. These cylindrical containers A have conical bottoms a, from which settling yeast can easily be removed by a tap b. A cooling liquid flows through the space formed by the double wall c, which enters at χ and exits at y.

Nach Vollendung der Gärung erleichtert die Kälte die Erhaltung und Einkörperung der Kohlensäure während des Abziehens.After fermentation is complete, the cold makes it easier to preserve and incorporate the Carbonic acid during removal.

Man füllt die Behälter A, die gewöhnlich einen großen Fassungsraum haben, derart vollständig mit gärungsfähiger Flüssigkeit an, daß gar kein Gasraum zwischen der Flüssigkeit und der oberen Wand bleibt. Die Behälter werden dann hermetisch verschlossen und mit einer Druckpumpe B in Verbindung gebracht, durch welche Flüssigkeit derselben Art wie die in den Behältern A enthaltene unter Ausschluß von Gas oder Luft so lange eingeführt wird, bis die Flüssigkeit in den Behältern unter einem Druck von 6 bis 20 und mehr Atm., je nach der Art der Flüssigkeit, steht.The container A, which usually has a large capacity, is filled so completely with fermentable liquid that no gas space remains between the liquid and the upper wall. The containers are then hermetically sealed and connected to a pressure pump B , through which liquid of the same type as that contained in containers A is introduced with the exclusion of gas or air until the liquid in the containers is under a pressure of 6 to 20 and more atmospheres, depending on the type of liquid.

Die Pumpe B besteht aus massivem Silber, welches das einzige Metall ist, das trotz Ab-The pump B is made of solid silver, which is the only metal that is

Claims

use by friction never chemically

is attacked by the organic acids of the fermented drinks. But she could can also be made of other material.

The pump is designed in such a way that the liquid contained in the container A can never be subjected to a suction effect which could release gas in the same.

When the maximum pressure by means of the pump

ίο is reached, the connection between the container and the latter remains closed by a flap d made of solid silver under the action of the spring r; the spring is set in such a way that the flap lifts at a certain pressure and then releases a very small opening which closes again by itself as soon as the pump no longer exerts excess pressure. The liquid therefore always remains in the hermetically sealed containers under the intended maximum pressure.

All parts that come into contact with the liquid, such as taps, valves, flaps etc., are made of solid silver or crystal glass; likewise the tubes are made of pure silver. The enamel of the container must be absolutely free of all traces of metallic salts, the compounds could form with the organic acids of the fermented liquids.

Each of the containers A also carries a special valve e, which dips into the middle of the liquid, is under the pressure of the spring f and is regulated so that it remains closed up to the maximum pressure set, but as soon as this is exceeded, it is easy raises to allow a small amount of liquid to flow out, sufficient to return the pressure to the maximum allowable pressure.

Since the fermentable liquid is thus enclosed and compressed as soon as the yeast attacks the sugar in order to split it into alcohol and carbonic acid, so is the carbonic acid formed under a pressure so high that it is released from the liquid cannot escape, but is bound.

When fermentation is over, the fermented liquid has a percentage bound Carbonic acid, which is far higher than that of sparkling wine and bottom-fermented Beers. The yeast accumulated in the lower conical part of the container will now ejected and the liquid brought to the lowest possible temperature so that the Proteins that could later cloud the liquid coagulate. The fermented liquid is then passed through sterilized asbestos filters under pressure and bottled or tons bottled for export.
