Abstract

To separate two components, specifically small amounts of high-melting fats from low-melting fats, normally a filtration with the aid of a filtration aid is carried out and, in order to separate valuable fats from the resulting filter cake, and to regenerate the filtration aid itself, a process is proposed in which the filter cake is heated and made liquid, and the second filter cake resulting from filtration is washed with the heated abovementioned low-melting fats, and subsequently the filtrate produced in the last step is cooled, and the solidified high-melting fats are separated by a final filtration step.

Description

hilfsmittel und die Rückgewinnung von hochwertigen Fetten aus Filtrationsrückständen bei der Winterisierung von Speiseölen und -Fetten In der Speiseöl- und Fettindustrie werden die hochschmelzenden Fraktionen aus Ölen und Fetten durch Auskristallierung und nachfolgender Filtration getrennt. Bei bestimmten Fettarten, z.B. Sonnenblumenöl, bereiten die Filtrationsvorgänge (Winterisierung) grosse Schwierigkeiten. aids and the recovery of high-quality fats from filtration residues in the winterization of edible oils and fats In the edible oil and fat industry the high-melting fractions of oils and fats are made by crystallization and subsequent filtration separated. With certain types of fat, e.g. sunflower oil, the filtration processes (winterization) cause great difficulties.

Die auszuscheidenden Fraktionen sind oft in geringen Mengen in Form von Kleinstkristallen vorhanden, die, ohne eine Zugabe von Filterhilfsmittel, nur mit einem hohen unwirtschaftlichen Aufwand auszufiltrieren sind. Aber gerade dieses erforderliche Filterhilfsmittel, das z.B.The fractions to be eliminated are often in small quantities in the form of tiny crystals are present, which, without the addition of filter aids, only are to be filtered out with a high uneconomical effort. But just this required filter aids, e.g.

für der Winterisierung von Sonnenblumenöl in Mengen von bis zu 1,0% dem zu filtrierenden Fett beigegeben werden muss, bereitet weitere erhebliche Schwierigkeiten; Ca.for winterizing sunflower oil in quantities of up to 1.0% must be added to the fat to be filtered, causes further considerable difficulties; Approx.

Zwei Drittel der resultierenden Filterkuchen besteht aus wertvollen Ölen und Fetten und ohne deren Rückgewinnung wird das Verfahren weitgehend unrentabel.Two thirds of the resulting filter cake consists of valuable Oils and fats and without their recovery, the process becomes largely unprofitable.

Verschiedene Verfahren sind schon bekannt bei denen der Filterkuchen durch Lösungsmittel extrahiert wird, wobei das Filterhilfsmittel regeneriert und wiederverwendet wird.Various processes are already known for those of the filter cake is extracted by solvent, wherein the filter aid is regenerated and is reused.

Z.B.: Der jetzige Stand der Technik für Sonnenblumenölwinterisierung kann aus der Veröffentlichung von W.Kehse, "fette, seife, anstrichmittel" 81, 463-466 (1979) entnommen werden. Solche erfahren haben sich aufgrund der Explosionsgefahr und der kostspieligen Arbeitsweise bis jetzt nicht durchsetzen können. Es kommt dazu, daß die dabei zurückgewonnenen Fette immer noch die hochschmelzenden Fraktionen enthalten die, mindestens bei der Sonnenblumenöl-Herstellung, zu einem beträchtlichen Wertverlust führen. In einer anderen vorgeschlagenen Methode, die sich jedoch nicht bewährt hat, wurde der Filterkuchen durch erhitztes Gas ausgeblasen.E.g .: The current state of the art for sunflower oil winterization can be found in the publication by W. Kehse, "fats, soap, paints" 81, 463-466 (1979). Such have been experienced due to the risk of explosion and the costly way of working have not yet been able to enforce. It is coming to the fact that the fats recovered are still the high-melting fractions contain that, at least in sunflower oil production, to a considerable extent Lead to loss of value. Another suggested method, however, is not has proven successful, the filter cake was blown out by heated gas.

Die Aufgabe dieser Erfindung ist die Entwicklung eines Gesamtverfahrens, das 1) den entstehenden Filterkuchen wirtschaftlich und ohne die Verwendung von gefährlichen Lösungsmitteln, Ausblasen oder sonstigen Fremdmitteln in zwei Komponente trennt, nämlich das wiederverwendbare Filterhilfsmittel und eine Fettphase bestehend aus wertvollen Fetten und hochschmelzenden Fraktionen und 2) die hochschmelzenden Fraktionen wirtschaftlich trennt, Diese Aufgaben werden erfindungsgemäß gelöst durch Erhitzen des Filterkuchens oberhalb des Schmelzpunktes der enthaltenen hochschmelzenden Fraktionen und einer nachfolgenden Filtration der resultierenden Suspension; wobei der dadurch entstandenen Filterkuchen anschließend mit erhitztem Fett ausgewaschen wird. Der Filterkuchen von diesem letzten Vorgang wird als Filterhilfsmittel in dem Hauptverfahren wiederverwendet.The object of this invention is to develop an overall process that 1) the resulting filter cake economically and without the use of hazardous solvents, blowing out or other foreign matter in two component separates, namely the reusable filter aid and a fat phase from valuable fats and high-melting fractions and 2) the high-melting ones Separating fractions economically, These objects are achieved according to the invention by Heating the filter cake above the melting point of the high-melting point contained Fractions and a subsequent filtration of the resulting suspension; whereby the resulting filter cake is then washed out with heated fat will. The filter cake from this last operation is used as a filter aid in reused the main process.

Das Filtrat, bestehend aus Fetten und hochschmelzenden Fraktionen, wird gekühlt (winterisiert) und die resultierende Suspension, ohne eine Zugabe von Filterhilfsmittel, filtriert.The filtrate, consisting of fats and high-melting fractions, is cooled (winterized) and the resulting suspension without an addition of Filter aid, filtered.

Der Filterkuchen von diesem Vorgang besteht hauptsächlich aus den unerwünschten hochschmelzenden Fraktionen.The filter cake from this process consists mainly of the undesirable high melting point fractions.

Um dieses neuartigen Verfahren durchzuführen werden vorzugsweise Vakuumband filter der Gattung wie in Patentschrift DT PS 23 23 082 beschrieben verwendet.Vacuum belts are preferred to perform this novel process filter of the genus as in patent specification DT PS 23 23 082 described used.

Ein Ausführungsbespiel dieser neuen Verfahrensweise wird nunmehr anhand der Zeichnung Ahb. 1 beschrieben: Aus dem Hauptverfahren 1 wird der Filterkuchen, bestehend aus Filterhilfsmittel, hochschmelzenden Fraktionen und Fetten in dem beheizten Behälter 2 hineingeführt. Die Schmelz suspension in Behälter 2 wird absatzweise durch die Leitung 4 in das Vakuumband-Filter 5 hineingesäugt, filtriert und änschließend wird der entstandene Filterkuchen durch erhitztes Fett aus der Leitung 6 ausgewaschen.An exemplary embodiment of this new procedure will now be based on the drawing Ahb. 1: The main process 1 becomes the filter cake, consisting of filter aid, high-melting fractions and fats in the heated one Container 2 introduced. The enamel suspension in container 2 is batchwise sucked through the line 4 into the vacuum belt filter 5, filtered and finally the resulting filter cake is washed out of line 6 by heated fat.

Dieser ausgewaschene Filterkuchen wird dann absatzweise aus dem Filter 5 zusammen mit beheiztem Fett aus der Leitung 9 in den Behälter 8 hineingeführt. Die entstandene Suspension wird dann durch'Pumpe 11 in das Hauptverfahren 1 zurückgeführt. Das Filtrat vom Filter 5 wird mittels Vakuumpumpe 7 durch den Wärmeaustauscher 10 hindurchgepumpt. Die resultierende Suspension aus erstarrten hochschmelzenden Fraktionen in flüssigen Fetten wird absatzweise in das Vakuumbandfilter 13 hineingesaugt und filtriert.This washed-out filter cake is then gradually removed from the filter 5 fed into the container 8 together with heated fat from the line 9. The resulting suspension is then returned to the main process 1 by means of the pump 11. The filtrate from the filter 5 is passed through the heat exchanger 10 by means of a vacuum pump 7 pumped through. The resulting suspension of solidified high-melting fractions in liquid fats is intermittently sucked into the vacuum belt filter 13 and filtered.

Das Filtrat, bestehend aus wertvollen Fetten, wird mittels Vakuumpumpe 14 durch die Leitung 17 in das Hauptverfahren 1 zurückgepumpt. Der Filterkuchen vom Filter 13, bestehend aus erstarrten hochschmelzenden Fraktionen und Fetten, wird im Auffangbehälter 16 aufgefangen.The filtrate, consisting of valuable fats, is pumped up using a vacuum pump 14 pumped back through line 17 into main process 1. The filter cake from the filter 13, consisting of solidified high-melting fractions and fats, is collected in the collecting container 16.
