Description
Verfahren zum Reinigen und Entfärben von zuckerhaltigen Säften, insbesondere von Dicksäften, mittels Entfärbungskohle o. dgl. Bisher wurde.beider Reinigung von Zuckersäften mit Entfärbungskohle o. dgl. regelmäßig eine ziemlich beträchtliche :Menge dieser immer sehr kostspieligen Entfärbungsmaterialienbenötigt und selbst bei Wiederbrauchbarmachung der Entfär@bungskohle nach bekanntem Verfahren häuften sich die Kosten für die Entfärbungskohle zu namhaften Beträgen an.Process for cleaning and decolorizing sugary juices, in particular of thick juices, by means of decolorizing charcoal or the like. So far, was.beider cleaning of Sugar juices with decolorizing charcoal or the like. Regularly a fairly substantial one : Amount of these decolorizing materials, which are always very expensive, needed and yourself when the decolorizing charcoal was recycled using known methods the cost of decolorizing charcoal is substantial.
Es hat sich nun ;herausgestellt, :däß man mit erstaunlich geringen Mengen von Entfärbungskohle auskommen kann, -wenn man abweichend von der bisherigen Arbeitsweise die Entfärbungskohle gleichzeitig mit anderen Entfärbungsmitteln einwirken läßt undl mit Kalk zusammen niederschlägt. Hierbei werden unerwartet große Mengen von färbenden Bestandteilen mit niedergeriissen und filtrierbar abgeschieden, während der gereinigte Zuckersaft hervorragend klare und reine Farbe .besitzt.It has now been found: that one can with astonishingly small Quantities of decolorizing charcoal can do, -if one deviates from the previous one Working method act the decolorizing carbon at the same time as other decolorizing agents lets andl precipitates together with lime. This results in unexpectedly large amounts of coloring constituents with torn down and filtered while separated the purified sugar juice is extremely clear and pure in color.
Man verfährt zweclcmäß@iig folgendermaßen: Man setzt beispielsweise auf i cbm Dicksaft von 5o bis 6o° Brix z .bis 3 1 Kalkmilch, bei Bedlrf auch mehr, ferner eine Käeselbgur-Holromehknischung (im Verhältnis i' : z) ebenfalls etwa 2 bis 3 1, !bei Bedarf auch mehr, und nur 3oo bis 5oo g Entfärbungskohle zu.One proceeds as follows: One sets, for example on i cbm thick juice from 5o to 6o ° Brix z. to 3 l milk of lime, if necessary also more, also a cheese-loaf-holromeh nibble (in the ratio i ': z) also about 2 up to 3 1,! if necessary even more, and only 3oo to 5oo g of decolorizing carbon.
Hierauf behandelt man die Mischung bei etwa 9o° C mit Kohlensäure oder schwefliger Säure, zweckmäßig bis, zu einer Alkalität von 0,01 bis o,o2, und erwärmt dann vorteilhaft bis etwa ioo°, notfalls auch darüber.The mixture is then treated with carbonic acid at about 90 ° C or sulphurous acid, expediently up to an alkalinity of 0.01 to 0.02, and then heated advantageously up to about 100 °, if necessary also above.
Alsdann läßt sich der Saft einwandfrei durch Pesssen abfiltrienen, gibt in den Pressen gute Kuchen, .die nach dem Ausdampfen der Presse vorteilhaft wieder zur ersten Saturation oder in die Scheidung zurückgegeben werden, damit -das lange Absüßen vermieden und die Entfärbungskohle nachträglich .bis auf den letzten Rest ausgenutzt wird, indem sie im Dünnsaft entfärbend wirkt.Then the juice can be filtered off perfectly by pessing, makes good cakes in the presses, which are beneficial after the press has evaporated be returned again to the first saturation or into divorce so that -that Avoided long sweetening and the decolorization charcoal afterwards, except for the last one The rest is exploited by having a decolorizing effect in the thin juice.
Praktische Versuche haben ergeben, daß man aus einem so ;behandelten Dicksaft vollständig weißen Zucker erhalten kann.Practical experiments have shown that one treated in this way Thick juice can contain completely white sugar.
Gut geeignet -steine unter :dem Namen Entfärbungskohle »L & V« im Handel blefindliche, auf Kieselsäureswbstrat niedergeschlagene Entfärbungskohle. Doch sind auch. andere Entfärbungskohlen, z. B. Knochenkohle, brauchbar.Well suited - stones under: the name decolorization carbon »L & V« commercially leaded decolorizing carbon deposited on silica substrate. But are also. other decolorizing carbons, e.g. B. charcoal, useful.
Sollte ausnahmsweise !die angegebene Menge von 3oo bis 5oo g Entfärbungskohle auf i cbm Saft von 5o ;bis 6o° Brix nicht ganz ausreichen, so wird auf Grund- von Vorversuchen die .Menge um eine Kleinigkeit erhöht.As an exception, the specified amount of 300 to 500 g decolorizing carbon should be used on 1 cbm of juice from 5o; to 60 ° Brix is not quite sufficient Preliminary attempts, the amount increased by a trifle.
Durch das neue Verfahren ,wird auch Entfärbungskohle verwendbar, idi.e bisher wegen ihrer ungeeigneten Körnung sich für die Filtration nicht eignete.With the new process, decolorizing carbon can also be used, idi.e was previously unsuitable for filtration because of its unsuitable grain size.
