(Reg.-Bez. Merseburg).(Reg.-Bez. Merseburg).
Nach dem bisher in den Zuckerfabriken üblichen Verfahren werden die Zuckersäfte durch Behandeln mit Aetzkalk (Kalkmilch) und Saturiren mit Kohlensäure oder mit dieser und schwefliger Säure gereinigt. Aber es werden, wie allgemein bekannt ist, die bei höherer Temperatur abgeschiedenen Eiweifskörper und anderen organischen NichtzuckerstofFe entweder nur unvollständig gefällt oder infolge der Wirkung des Aetzkalkes zum gröfsten Theile wieder gelöst. Durch diese bleibende Verunreinigung der Zuckersäfte mit Melassebildern wird die Ausbeute an Rohzucker bedeutend vermindert.The sugar juices are cooked through according to the usual procedure in the sugar factories up to now Treat with caustic lime (lime milk) and saturate with carbonic acid or with this and Purified sulphurous acid. But, as is well known, there will be those at higher levels Temperature separated proteins and other organic non-sugars either precipitated only incompletely or largely again as a result of the action of the caustic lime solved. Due to this permanent contamination of the sugar juices with molasses images, the Raw sugar yield significantly reduced.
Durch das neue Verfahren, welches sich durch Einfachheit auszeichnet, werden die angeführten. Uebelstände beseitigt, und es wird infolgedessen eine höhere Ausbeute an Rohzucker und eine gröfsere Reinheit desselben erreicht werden.Due to the new procedure, which is characterized by its simplicity, the listed. Disadvantages removed, and as a result there will be a higher yield of raw sugar and a greater purity of it can be achieved.
Das Verfahren gründet sich darauf, dafs Eisenoxychlorid gelöstes Eiweifs fällt, und dieser Niederschlag wird, wie wir gefunden haben, durch Aetzkalk nicht gelöst.The process is based on the fact that iron oxychloride precipitates dissolved albumen, and this As we have found, precipitation is not dissolved by caustic lime.
Gleichzeitig fallen mit dem Eiweifs auch andere organische NichtzuckerstofFe aus. Das von uns angewandte Präparat hatte die Zusammensetzung Fe., Cl6 + 8 Fe2 (O H)6, doch lassen sich auch noch höher basische Verbindungen mit demselben Erfolge anwenden.At the same time, other organic non-sugar substances also precipitate with the protein. The preparation we used had the composition Fe., Cl 6 + 8 Fe 2 (OH) 6 , but more highly basic compounds can also be used with the same success.
Im Fabrikbetriebe würde sich das Verfahren folgendermafsen gestalten: Der Diffusionssaft, wie er aus der DifFusionsbatterie kommt, wird, ohne, erwärmt zu werden, mit Kalkmilch bis zur Alkalität 0,08 pCt. und auf je 60 1 Rohsaft mit 1J2 1 Eisenoxychlorid versetzt, gut umgerührt und dann noch mit Kalkmilch bis zu ι pCt. Aetzkalk, auf Rüben berechnet, versetzt. Man erwärmt bis 8o° C. und saturirt mit Kohlensäure bis 0,1 pCt. Alkalität. Der nun aufgekochte Saft geht durch die Filterpresse und wird in der zweiten Saturation zunächst mit ]/4 1 Eisenoxychlorid auf 100 1 Saft und darauf mit Y4 pCt. Aetzkalk, auf Rüben berechnet, versetzt, gut gemischt, mit Kohlensäure oder schwefliger Säure bis zur Alkalität 0,05 pCt. absaturirt und schliefslich, wie bekannt, weiter behandelt. Bei den Laboratoriums-Versuchen ergab sich ein Steigen des Reinheitsquotienten von 75 beim Rohsaft auf 85 beim Dünnsaft und von 82 beim Rohsaft auf go beim Dünnsaft.In the factory, the process would be as follows: The diffusion juice, as it comes from the diffusion battery, is mixed with milk of lime to an alkalinity of 0.08 pCt without being heated. and 1 J 2 1 iron oxychloride is added to every 60 1 raw juice, stirred well and then with milk of lime up to ι pCt. Caustic lime, calculated on beets, added. It is warmed to 80 ° C. and saturated with carbonic acid to 0.1 pCt. Alkalinity. The now boiled juice passes through the filter press and in the second first with Saturation] / 4 1 1 100 on iron oxychloride juice and with it, Y 4 per cent. Caustic lime, calculated on beets, mixed, well mixed, with carbonic acid or sulphurous acid up to an alkalinity of 0.05 pCt. Absatured and finally, as is known, treated further. The laboratory tests showed an increase in the purity quotient from 75 for the raw juice to 85 for the thin juice and from 82 for the raw juice to go for the thin juice.
In den so gereinigten Säften war Eisen nicht nachzuweisen. Wir versuchen zur Zeit, unser Verfahren auch auf die Reinigung der Melasse anzuwenden.No iron was found in the juices purified in this way. We are currently trying our Procedure also apply to the cleaning of the molasses.
Das Eisenoxychlorid ist bei fabrikmäfsiger Herstellung ein .billiges Präparat.The iron oxychloride is a cheap preparation when it is factory-made.
