Die zu entfettenden Knochen werden in einen Behälter gefüllt, welcher hermetisch verschliefsbar, durch Dampf heizbar ist und mit einem Kühlapparate und einem oder mehreren Gefäfsen, in welchen sich concentrate Schwefelsäure befindet, in Verbindung steht. Auch der Kühlapparat und die Schwefelsäuregefäfse können nach aufsen hermetisch abgeschlossen werden.The bones to be defatted are filled into a container which can be hermetically sealed, can be heated by steam and with a cooling device and one or more vessels in which sulfuric acid is concentrated is in communication. The cooling apparatus and the sulfuric acid vessels can also hermetically sealed to the outside.
Um die eingefüllten Knochen zunächst zu trocknen, erzeugt man unter fortdauerndem Erwärmen des Knochenbehälters in diesem Behälter und dem damit verbundenen Kühler und den Schwefelsäuregefäfsen mittelst einer Luftpumpe ein Vacuum. Infolge dessen verwandelt sich die in den Knochen enthaltene Feuchtigkeit rasch in Wasserdampf, welcher vom Kühlapparate und der Schwefelsäure in den Gefäfsen gleichsam angesaugt und condensirt wird, so dafs das einmal erzeugte Vacuum sich von selbst erhält' und die Knochen schnell austrocknen.In order to first dry the filled bones, they are produced with continuous heating of the bone container in this container and the associated cooler and the sulfuric acid vessels by means of an air pump a vacuum. As a result, the moisture contained in the bones is transformed quickly in water vapor, which from the cooling apparatus and the sulfuric acid in the vessels is sucked in and condensed, so to speak, so that the vacuum once generated is self-contained gets' and the bones dry out quickly.
Sind die Knochen im Behälter trocken geworden, so hebt man das Vacuum auf, läfst die zur Entfettung der Knochen bestimmte Flüssigkeit (Schwefelkohlenstoff, Benzin oder ähnliche flüchtige Lösungsmittel für Fett) unter fortdauernder gelinder Erwärmung auf und durch die Knochen fliefsen, welche in trockenem Zustande das in ihnen enthaltene Fett schnell an das Lösungsmittel abgeben. Die so gewonnene Fettlösung läfst man sodann in einen Destillirapparat abfliefsen, in welchem das Lösungsmittel vom Fett abdestillirt wird.If the bones in the container have become dry, the vacuum is lifted, and you run the liquid intended for degreasing the bones (carbon disulfide, gasoline or similar volatile solvents for fat) with continued gentle heating up and through the bones flow, which, when dry, quickly attack the fat contained in them release the solvent. The fat solution obtained in this way is then poured into a still drain, in which the solvent is distilled off from the fat.
Zu den im Behälter befindlichen entfetteten Knochen läfst man nun zunächst, um das noch anhaftende Lösungsmittel zu verjagen, einen kräftigen Dampfstrahl treten und condensirt die entweichenden Dämpfe des Lösungsmittels durch einen besonderen Kühler; hierauf läfst man den directen Dampf etwas langsamer zuströmen und kühlt den obersten Theil des Knochenbehälters derart ab, dafs sich der Dampf oben zu heifsem Wasser condensirt, das den aus den Knochen austretenden Leim auflöst und in den unteren Theil des Apparates führt.You now first run to the defatted bones in the container, around that To drive away adhering solvents, enter a powerful jet of steam and condense the escaping solvent vapors through a special cooler; then you run the The direct steam flows in somewhat more slowly, and cools the uppermost part of the bone-vessel in such a way that the steam condenses at the top to hot water, which dissolves from the bones dissolves emerging glue and leads into the lower part of the apparatus.
Bei diesem Verfahren werden die Knochen ohne starke Erhitzung vollständig ausgetrocknet und dadurch zur Entfettung derart vorbereitet, dafs man das Lösungsmittel unter gewöhnlichem Luftdruck auf die Knochen einwirken lassen kann.In this procedure, the bones are completely dried out without excessive heating and thereby prepared for degreasing in such a way that the solvent is usually removed Air pressure can act on the bones.
