KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der vorliegenden Erfindung ist ein Verfahren, durch welches das in wässerigen Lösungen, z. B. Brennereischlempe, Zuckersaft etc., enthaltene vegetabilische Eiweifs derart ausgeschieden oder zum Gerinnen gebracht , wird, dafs es selbstständig oder im Verein mit anderen Stoffen durch mechanische Vorrichtung oder durch Absetzen von der Flüssigkeit getrennt werden kann.The present invention is a method by which the in aqueous Solutions, e.g. B. distillery mash, sugar juice, etc., contained vegetable protein such excreted or coagulated, it becomes independent or in association with it separated from other substances by mechanical means or by settling from the liquid can be.
Das Verfahren besteht in der Ueberführung des in wässeriger Lösung befindlichen Eiweifses in die unlösliche Form durch Einwirkung von saurem bernsteinsauren Kalk oder saurem bernsteinsauren Eisen.The process consists in transferring the protein from the aqueous solution into the insoluble form by the action of acidic succinic lime or acidic succinic acid Iron.
Man fügt daher entweder der vegetabilisches Eiweifs enthaltenden Lösung eines dieser beiden sauren Salze zu, oder führt, wenn sich freie Bernsteinsäure in der wässerigen Lösung vorfindet, diese in eines der beiden genannten sauren Salze über. Am bequemsten und billigsten geschieht die Ueberführung der freien Bernsteinsäure in sauren bernsteinsauren Kalk mittelst kohlensauren Kalkes bei einer Temperatur von 6o° C.Either one of these two is added to the solution containing vegetable protein acidic salts too, or if there is free succinic acid in the aqueous solution finds this in one of the two acid salts mentioned. Most convenient and The cheapest is the conversion of the free succinic acid into acidic succinic lime by means of carbonate of lime at a temperature of 60 ° C.
Hieraus ergiebt sich das Verfahren zur Abscheidung von vegetabilischem Eiweifs aus wässeriger Lösung wie folgt:The process for separating vegetable protein results from this aqueous solution as follows:
Ist freie Bernsteinsäure in der ursprünglichen Lösung nicht vorhanden, so bringt man dieselbe auf ca. 6o° C. und fügt freie Bernsteinsäure und kohlensauren Kalk hinzu oder auch das fertige saure Salz, oder erzeugt das saure Salz auf irgend eine bekannte Weise in der wässerigen Lösung; beispielsweise bei Anwendung sauren bernsteinsauren Kalkes werden auf 1001 Lösung vegetabilischen Eiweifses, welche in ι 000 Theilen etwa 900 Theile Wasser enthält, 224 g saurer bernsteinsaurer Kalk verwendet. Man digerirt so lange, bis eine entnommene Probe ein klares, in der Hauptsache eiweifsfreies Filtrat ergiebt. Dies zeigt das Gerinnen des in Lösung gewesenen Eiweifses an. Hierauf filtrirt man den Niederschlag in bekannter Weise durch Filterpressen etc. oder läfst absetzen, oder trennt in bekannter Weise die festen von den flüssigen Massen. Zu diesem Zwecke kann die behandelte Lösung zunächst abgekühlt werden, um allen sauren bernsteinsaureti Kalk im Rückstande zu gewinnen, oder man kann, wenn sich durch Abkühlung des Filtrats in diesem saurer bernsteinsaurer Kalk abscheidet, das Filtrat durch Absetzen oder Filtriren von dieser Abscheidung trennen und letztere mit dem ersten Niederschlag vereinigen.If there is no free succinic acid in the original solution, bring it up to about 60 ° C. and adds free succinic acid and carbonate of lime or else the finished acidic salt, or produces the acidic salt in some known manner in the aqueous solution; for example when using acidic succinic lime to 1001 solution of vegetable protein, which in 1000 parts contains about 900 parts of water, 224 g of acidic succinic lime was used. One digests until one is removed Sample gives a clear, mainly protein-free filtrate. This shows curdling of the protein that has been in solution. The precipitate is then filtered in a known manner Way by filter presses etc. or lets settle, or separates in a known manner solid from liquid masses. For this purpose, the treated solution can must first be cooled in order to obtain all the acidic amber-lime in the residue, or you can, if by cooling the filtrate in this acidic, succinic acid Lime separates the filtrate by settling or filtering from this deposit separate and combine the latter with the first precipitate.
Enthält aber die ursprüngliche Lösung, aus der das Eiweifs abgeschieden werden soll, genügende Menge freier Bernsteinsäure, so erwärmt man die Eiweifslösung, welche in 1000 Theilen etwa 900 Theile Wasser enthält, auf ca. 6o° C. und fügt für je 100 1 Lösung 200 g reinen kohlensauren Kalk in irgend welcher Gestalt zu und digerirt wieder so lange, bis bei entnommener Probe dasBut if the original solution from which the protein is to be separated contains sufficient amounts Amount of free succinic acid, the protein solution which is in 1000 parts contains about 900 parts of water, to about 60 ° C. and adds 1 for every 100 Solution Adds 200 g of pure carbonate of lime in any form and digests it again until the sample is taken
Filtrat wie oben erwähnt erscheint. Ist freie Bernsteinsäure zwar vorhanden, aber nicht in genügender Menge, so wird das Fehlende wie oben zugesetzt oder gebildet.Filtrate appears as mentioned above. Is free succinic acid present, but not in sufficient amount, the missing is added or formed as above.
Bei Anwendung sauren bernsteinsauren Eisens sind die dem Kalksalz äquivalenten Mengen desselben zuzusetzen. . -When using acidic succinic iron, the amounts are equivalent to the calcium salt to add the same. . -
