Description
Verfahren zum Herstellen säurefester Filtersteine Gegenstand des Hauptpatents ist ein Verfahren zum Herstellen säurefester Filtersteine unter Verwendung körnigen, säurefesten Steinmaterials, dessen Kennzeichen darin besteht, daß die säurefesten Körner mittels eines Bindemittels zu Steinen geformt, darauf in Säure und nach erfolgter Trocknung in eine Lösung von Zuckermelasse oder zuckerbildenden Stoffen getaucht werden, worauf in bekannter Weise durch Erhitzen eine Karamellisierung und Zersetzung des Zuckers bewirkt wird.Process for the production of acid-resistant filter stones the subject of the main patent is a process for the production of acid-resistant filter stones using granular, acid-resistant stone material, the characteristic of which is that the acid-resistant Grains formed into stones by means of a binder, then in acid and afterwards Drying dipped in a solution of sugar molasses or sugar-forming substances whereupon a caramelization and decomposition by heating in a known manner of sugar is effected.
Es brt sich nun gezeigt, zur Beschleunigung und Verbesserung dieses Verfahrens die mit Säure behandelten Steine zweckmäßig vor ihrem Einbringen in die Lösung aus Zucltermelasse oder zuckerbildenden Stoffen künstlich zu trocknen. It has now been shown to speed up and improve this The acid-treated stones are expediently placed in the process before they are introduced Artificially drying a solution of sugar molasses or sugar-forming substances.
Des weiteren wurde gefunden, daß es von Vorteil sein kann, die Steine nach der Schlußerhitzung von neuem in ein Säurebad- einz. tauchen, künstlich zu trocknen, anschließend mit Zuckerlösung zu tränken, zu karamellisieren und diese Behandlung verschiedene Male zu wiederholen. It has also been found that it can be beneficial to use the stones after the final heating again in an acid bath. diving, artificially too dry, then soak with sugar solution, caramelize and this Repeat treatment several times.
Ausführungsbeispiel I7 ccm säurefeste Steine (z. B. säurefeste Bruchsteine der Firma Didier) werden mit 4,6 ccm Kitt (z. B. sogenannte SW io-Mehl) und 2 ccm Wasserglas geformt und im Ofen bei etwa 800 getrocknet. Die getrockneten Steine werden noch an der Luft etwa 48 Stunden nachgetrocknet. Danach werden diese Steine in ein Säurebad von z. B. IoOloiger Schwefelsäure I2 bis 24 Stunden lang getaucht und anschließend künstlich getrocknet, und zwar zweckmäßig bei etwa 800. Die infolge der Säurebehandlung porig gewordenen Steine werden nunmehr etwa I2 bis 24 Stunden lang in eine etwa 8°/Oige Zuckerlösung ein,getaucht und getrocknet, wozu zweckmäßig Lufttrocknung von etwa 24 Stunden angewendet wird. Die trocknen Steine werden darauf 24 Stunden lang bei I00° karamellisiert. Embodiment 17 ccm of acid-resistant stones (e.g. acid-resistant rubble stones from Didier) are mixed with 4.6 ccm of putty (e.g. so-called SW io flour) and 2 ccm Shaped water glass and dried in the oven at about 800. The dried stones are dried in the air for about 48 hours. After that these stones are in an acid bath of z. B. IoOloiger Sulfuric Acid I2 immersed for up to 24 hours and then artificially dried, expediently at about 800. The result Stones that have become porous after the acid treatment are now about 12 to 24 hours long immersed in an 8% sugar solution, dipped and dried, for which purpose it is useful Air drying of about 24 hours is applied. The dry stones are on it Caramelized for 24 hours at 100 °.
Die Steine werden danach wiederum in ein Säurebad eingetaucht, künstlich getrocknet, anschließend mit Zuckerlösung getränkt und karamellisiert. Das Verfahren wird etwa vier- bis fünfmal wiederholt. The stones are then again immersed in an acid bath, artificially dried, then soaked with sugar solution and caramelized. The procedure is repeated about four to five times.
