Zur Erzeugung einer den jetzigen hohen Anforderungen der Consumenten in Bezug auf Qualität entsprechenden Prefshefe aus Melasse ist es nöthig, letztere von ihren die dunkle Farbe und den schlechten Geruch bedingenden Bestandteilen zu befreien. Zu diesem Zwecke wird die Melasse mit schwefliger Säure und Zinkstaub auf ähnliche Weise behandelt, wie die Zuckersäfte nach dem bekannten Ransοnschen Verfahren.To generate one of the current high demands of consumers with regard to It is necessary to use the same quality pre-yeast from molasses, the latter of which is the dark one To get rid of the components that cause the bad smell. To this end the molasses is treated with sulphurous acid and zinc dust in a similar way as the sugar juices according to the well-known Ransonschen Procedure.
Während in letzterem Falle das Bestreben naturgemäfs dahin gerichtet ist, den Rübenzucker als solchen zu erhalten und jede Inversion desselben durch Säurezusatz oder durch Behandlung bei Temperaturen von über 500C. sorgfältig vermieden wird, ist es für den Zweck des den Gegenstand der Erfindung bildenden Verfahrens günstig, vorerst den Rübenzucker in Invertzucker überzuführen und erst dann die den schlechten Geruch und die dunkle Farbe der Melasse bedingenden organischen Verunreinigungen auszuscheiden. Die zu diesem Zwecke in Anwendung kommenden Reagentien sind Schwefelsäure, schweflige Säure, Zinkstaub und Kalkmilch, doch werden diese Reagentien in einer bis jetzt nicht üblichen Weise angewendet.While in the latter case the effort is naturally directed towards preserving the beet sugar as such and carefully avoiding any inversion of the same by adding acid or by treatment at temperatures above 50 ° C., it is for the purpose of the process forming the subject of the invention It is beneficial to first convert the beet sugar into invert sugar and only then to eliminate the organic impurities that cause the bad smell and dark color of the molasses. The reagents used for this purpose are sulfuric acid, sulphurous acid, zinc dust and milk of lime, but these reagents are used in a manner not heretofore common.
Die Melasse wird bis zu einer Concentration von ca. 30 Saccharometergraden verdünnt, mittelst Dampfes auf ca. 700 C. erwärmt und bei .The molasses is diluted to a concentration of approx. 30 saccharometer degrees, heated to approx. 70 ° C. by means of steam and at.
dieser Temperatur mit Schwefelsäure bis zur stark sauren Reaction versetzt. Hierdurch wird der Rübenzucker in Invertzucker übergeführt; aufserdem scheidet sich infolge des Säureüberschusses ein grofser Theil der in der Melasse enthaltenen übelriechenden Eiweifsstoffe ab, welche bei der nun folgenden Operation abfiltrirt werden.at this temperature with sulfuric acid until the reaction is strongly acidic. This will the beet sugar converted into invert sugar; In addition, due to the excess acid, it separates a large part of the malodorous proteins contained in the molasses, which are filtered off in the operation which now follows.
Zu dieser sauren, immer noch 700 C. heifsen Lösung wird ein vorher bestimmtes Quantum von schwefliger Säure, am zweckmäfsigsten in wässeriger Lösung-zugeführt, so zwar, dafs der Gehalt der ganzen Flüssigkeit an schwefliger Säure höchstens 0,2 pCt. beträgt. Gleichzeitig trägt man in die Flüssigkeit eine gewogene, dem Sa'ureüberschufs — auf Schwefelsäure berechnet — äquivalente Menge von Zinkstaub ein, der vorher in Wasser aufgeschlämmt wurde, und steigert die Temperatur unter fortwährendem Rühren bis nahe zum Kochen. Dabei tritt beinahe plötzlich eine weitgehende Entfärbung der Melasselösung ein, der bis dahin dunkelbraune Schaum wird lichtgelb, der Geruch nach schwefliger Säure ist im Verschwinden begriffen und herausgenommene Proben zeigen, dafs die Melasselösung sich glanzhell von einem rasch zu Boden sinkenden, flockigen und dunklen Niederschlage abscheidet.Acid thereto, still 70 0 C. torrid solution, a predetermined quantity of sulfurous acid solution fed-in on aqueous zweckmäfsigsten, so much, the content of the whole liquid sulfurous acid DAF than 0.2 per cent. amounts to. At the same time, a weighed amount of zinc dust equivalent to the excess acid - calculated in terms of sulfuric acid - which was previously suspended in water is added to the liquid, and the temperature is increased while stirring continuously until it is close to boiling. At the same time, the molasses solution almost suddenly became largely discolored, the foam, which had been dark brown until then, turned light yellow, the smell of sulphurous acid was disappearing, and samples taken showed that the molasses solution was separated from a fluffy, dark precipitate that quickly sank to the ground .
Es wird nun Kalkmilch bis zur neutralen Reaction zugesetzt, während die TemperaturMilk of lime is now added until the reaction is neutral, while the temperature
bis zum Siedepunkt steigt, und sodann mittelst Filterpresse heifs filtrirt. . .rises to the boiling point, and then filtered hot by means of a filter press. . .
Bei sehr unreiner Melasse ist eine Filtration vor der Neutralisation mit Kalkmilch nöthig. Das Filtrat ist ganz klar, geruchlos, von heller Farbe, sterilisirt und enthält den Zucker nur in Form von Invertzucker. Dasselbe wird mit Salzsäure angesäuert und bildet, mit der nöthigen Menge von peptonisirten Eiweifskörpern gemischt, eine zur Prefshefe und Spiritusfabrikation in ausgezeichneter Weise taugliche ■ Würze.In the case of very impure molasses, filtration is necessary before neutralization with milk of lime. The filtrate is quite clear, odorless, light in color, sterilized, and contains only the sugar in the form of invert sugar. It is acidified with hydrochloric acid and forms with the necessary Amount of peptonized albuminous bodies mixed, one for making pre-made yeast and alcohol an excellent ■ condiment.
