Abstract
(DE)
Verfahren zur Gewinnung von nativen Produkten, wie Ölen, Fetten und Wachsen und deren Derivaten, aus nativen Stoffgemengen im Zentrifugalfeld. Die Gewinnung der nativen Produkte wird dadurch erschwert, daß zwischen den flüssigen, nicht wasserlöslichen, nativen Produkten und dem sie einbettenden Gewebe Attraktionskräfte wirken und bei der Gewinnung in den Produkten andere Bestandteile gelöst sind oder als Schwebeteilchen vorliegen. Das Ausgangs-Stoffgemenge wird daher zusammen mit einem wasserlöslichen, organischen Lösemittel und gegebenenfalls Wasser zu einem Brei verarbeitet. Durch Zusatz des wasserlöslichen, organischen Lösemittels kann das Stoffgemenge im Zentrifugalfeld sauber in eine wäßrige und organische Phase aufgetrennt werden, wobei kein weiterer Reinigungsschritt der organischen Phase erforderlich ist. Das erfindungsgemäße Verfahren hat einen breiten Anwendungsbereich. Grundsätzlich kann es auf alle Stoffgemenge, die flüssige, organische Stoffe enthalten, angewendet werden, insbesondere auf pflanzliche und tierische Gewebe. Es eignet sich für die Gewinnung von Ölen aus Ölfrüchten oder Wachsen aus wachshaltigen Pflanzenteilen sowie für die Gewinnung von Fischöl aus Fisch.
(EN)
The extraction of native products is rendered difficult by the fact that attraction forces act between the liquid native products which are not water-soluble and the tissue incorporating them, and that other constituents are dissolved or present in the form of particles in suspension in the products during the extraction process. The initial substance mixture is, therefore, processed together with a water-soluble, organic solvent and optionally water to form a paste. The addition of the water-soluble, organic solvent enables the substance mixture to be separated cleanly into an aqueous phase and an organic phase in the centrifugal field, no further cleaning being necessary for the organic phase. The process according to the invention has a wide area of application. In principle, it can be applied to all substance mixtures containing liquid, organic substances, in particular to vegetable and animal tissue. It is suitable for extracting oils from oleaginous fruit or waxes from wax-containing plants, as well as for extracting fish oils.
(FR)
L'extraction de produits natifs est rendue difficile par le fait que des forces d'attraction interviennent entre les produits natifs, liquides, insolubles dans l'eau, et le tissu les renfermant, et par le fait que d'autres constituants sont dissous ou présents sous forme de particules en suspension dans les produits lors de l'extraction. Le mélange des matières de départ est donc traité avec un solvant organique soluble dans l'eau et, le cas échéant, avec de l'eau, pour donner une pâte. L'addition du solvant organique soluble dans l'eau permet de séparer nettement le mélange de matières dans le champ centrifuge en une phase aqueuse et une phase organique, sans nécessiter aucune étape supplémentaire de purification de la phase organique. Le procédé selon l'invention offre un large champ d'applications. Il peut être appliqué pour tous les mélanges de matières renfermant des substances organiques liquides, en particulier pour les tissus végétaux et animaux. Il se prête à l'extraction d'huiles à partir de fruits oléagineux ou de cire à partir de végétaux renfermant de la cire, ainsi qu'à l'extraction d'huile de poisson.
