Description

Verfahren zum Verarbeiten von fett- und leimhaltigen Abfällen Tierische Abfälle werden vor allem für die Gewinnung von Fett und Leim verarbeitet. Zuerst muß das Fett möglichst vollständig entfernt werden, da es bei der Verleimung stören und den Leim minderwertig machen würde. Außerdem soll das Ausgangsmaterial auch möglichst weitgehend entwässert «erden.Process for processing fatty and glue-containing waste Animal Waste is mainly processed for the production of fat and glue. First the fat must be removed as completely as possible, as it interferes with the gluing and make the glue inferior. In addition, the source material should also as far as possible drained «earth.

Es wurde ein einfaches Verfahren zum Verarbeiten von leim- und fetthaltigen Abfällen gefunden, welches eine gleichzeitige Entwässerung und Entfettung der Abfälle ermöglicht, so daß dann sofort mit der Verleimung begonnen werden kann. L)as Verfahren besteht im wesentlichen darin, daß die Abfälle mit organischen Fettlösungsmitteln vermischt werden und dann so lange destelliert wird, bis praktisch kein Wasser mehr mit übergeht. Das Fett löst sich dabei im Lösungsmittel, was durch zunehmende Entwässerung gefördert wird, da die gebräuchlichen Fettlösungsmittel wasserunlöslich sind und daher wasserhaltiges Gut ungenügend angreifen. Die Einwirkung des Lösungsmittels kann auch bei Unterdruck stattfinden. Ist die Entwässerung beendet, so kann das fetthaltige Lösungsmittel abgelassen werden, worauf die Lösungsmittelreste durch gespannten Wasserdampf aus dem Gut ausgetrieben werden, wobei gleichzeitig der Verleimungsprozeß eingeleitet wird.It became a simple method of processing glue and fat containing Waste found, which is a simultaneous dewatering and degreasing of the waste made possible, so that gluing can then be started immediately. L) as procedure consists essentially in that the waste with organic fat solvents are mixed and then distilled until there is practically no more water with passes. The fat dissolves in the solvent, which is caused by increasing dehydration is promoted, since the common fat solvents are water-insoluble and therefore attack water-containing material insufficiently. The action of the solvent can also take place under negative pressure. Once the drainage has ended, it can fatty solvents are drained, whereupon the solvent residues through strained water vapor are expelled from the property, at the same time the gluing process is initiated.

Als Lösungsmittel verwendet man zweckmäßig solche mit einem Siedepunkt über ioo°, z. B. Chlorkohlenwasserstoffe, vornehmlich Perchloräthylen, das für die Entwässerung besonders geeignet ist.The solvent used is expedient such with a boiling point above 100 °, e.g. B. Chlorinated hydrocarbons, primarily perchlorethylene, which is particularly suitable for drainage.
