Description
Läuterbottichboden Bisher liegt auf dem eisernen Gefäßboden des Läuterbottichs der metallene Senkboden im Abstand von etwa io mm. Eisen - und Bronze sind in der Spannungsreihe gegenüberstehende Metalle, so daß, wenn sich Maische oder Würze im Bottich befindet, ein elektrischer Strom fließt. Das Eisen wandert durch Elektrolyse von dem Bottichboden an die untere Seite des Senkbodens. Die Senkbodenfläche färbt sich dabei schwarz und wird vereisent. Das läßt sich chemisch nachweisen, wenn man den schwarzen Belag mit Rodankalium prüft. Bottichböden aus sehr weichem, schlecht gewalztem Eisen werden insbesondere rasch zerstört. Außerdem wird Bier durch Eisenaufnahme geschmacklich nachteilig beeinflußt; auch die porös und schwammig gewordene Eisenoberfläche hält trotz mechanischer Reinigung immer Extraktivstoffe fest, welche zur Säurung neigen, dadurch nimmt diese oberste Schicht einen widerlichen, an faulende Treber erinnernden Geruch an, der sich auch auf das Bier überträgt.Läuterbottich bottom So far lies on the iron vessel bottom of the lauter tun the metal false bottom at a distance of about 10 mm. Iron and bronze are in the Voltage series of opposing metals, so that if there is mash or wort in the Vat is located, an electric current flows. The iron migrates through electrolysis from the bottom of the tub to the lower side of the false bottom. The false bottom surface is colored turns black and is iced over. That can be proven chemically if you Checks the black coating with potassium rod. Vat bottoms made of very soft, bad rolled iron in particular are quickly destroyed. In addition, beer is made through iron absorption adversely affected taste; also the iron surface, which has become porous and spongy Despite mechanical cleaning, it always holds extractive substances that lead to acidification tend, thereby this top layer takes a disgusting, rotting grains reminiscent smell, which is also carried over to the beer.
Diese vielen Nachteile beseitigt die folgende konstruktive Abänderung des Läuterbottichbodens, welche sowohl bei alten Bottichen wie bei neuen möglich ist. Auf den vorhandenen eisernen Bottichboden i wird ein zweiter Boden a aus Metallblechen aufgelegt, der aus dem gleichen Material wie der Senkboden, z. B. aus Hartbronze, besteht. Die Befestigung der anzupassenden Metallplatten geschieht z. B. durch Verschraubung 3, durch Nietung o. dgl. Unebene Eisenböden werden zuerst nach sorgfältigem Abreiben und Trocknen mit Zement oder anderen Glättemitteln geebnet und vor dem Auflegen der Metallplatten mit einer Isolierschicht q., z. B. Lack, versehen. Der Metallboden wird vollkommen dicht verlegt, damit keine Flüssigkeit dazwischentreten kann. Das verhindert weitere Korrosionswirkung, weit sich gleiche Metalle gegenüberstehen. Der Senkboden liegt nun mit seinen Füßchen 6 auf dem Metallbelag s auf.The following design modification eliminates these many disadvantages of the lauter tun bottom, which is possible with old vats as well as with new ones is. A second floor a made of sheet metal is placed on the existing iron vat floor i placed, which is made of the same material as the false bottom, z. B. made of hard bronze, consists. The attachment of the metal plates to be adjusted is done, for. B. by screwing 3, by riveting or the like. Uneven iron floors are first removed after careful rubbing and drying with cement or other smoothing agents and leveled before laying the metal plates with an insulating layer q., e.g. B. paint provided. The metal floor is laid completely tight so that no liquid can get in between. That prevents further corrosive effects, as far as the same metals face each other. The false floor now rests with its feet 6 on the metal covering s.
