Die vorliegende neue Methode der Gewinnung von Fett aus animalischen Rohstoffen scheidet letztere in zwei Klassen:The present new method of obtaining fat from animal raw materials is different the latter in two classes:

a) Schlachthausfette oder Rohtalg,a) slaughterhouse fats or raw tallow,

b) Fettabfälle aus Schlächtereien, Abdeckereien, aus der Verarbeitung der Därme etc.b) Fat waste from slaughterhouses, covering shops, from processing the casings, etc.

Der Rohtalg, welcher vorzugsweise zur Gewinnung von Speisetalg (Kunstbutter etc.) benutzt werden soll, wird zunächst, wie auch anderwärts üblich und hier wie dort ausgeübt, der Einwirkung einer mechanischen Vorrichtung ausgesetzt, um die umschliefsenden Häute und Gewebe zu zerreifsen.The raw tallow, which is preferably used for the production of edible tallow (artificial butter, etc.) is to be exercised first, as is customary elsewhere and here as there, exposed to the action of a mechanical device around the enclosing skins and To tear tissue.

Die solchergestalt vorbereiteten Materialien werden alsdann in ein mit Aluminiumchlorttrlösung von ca. io° B. gefülltes Reservoir übergeführt, um hier 24 Stunden zu maceriren, worauf man sie aus der Flüssigkeit nimmt und abtropfen läfst.The materials prepared in this way are then immersed in an aluminum chloride solution from about 10 ° B. filled reservoir transferred to macerate here for 24 hours, whereupon they are removed from the liquid and allowed to drain.

Bei den unter b) genannten Rohmaterialien ist es vorher nöthig, dieselben behufs Entfernung aller Stoffe, welche dem Endproduct irgendwie Färbung oder üblen Geschmack mittheilen könnten, durch Auswaschen gründlich zu reinigen. Die gereinigten Materialien gelangen in eine Maschine, welche die Bestimmung hat, sie zu trocknen und zu einer breiigen Masse zu verarbeiten; diese wird nun ebenso, wie oben der Rohtalg, der Maceration in der Aluminiumchlorürlösung von 10⁰B. unterworfen. Nach 24 stündiger Maceration läfst man abtropfen und setzt den Brei zur Entfernung der wässrigen Lösung einer kalten Pressung aus.In the case of the raw materials mentioned under b), it is necessary beforehand to wash them thoroughly by washing them out to remove all substances which might impart color or bad taste to the end product. The cleaned materials get into a machine, which has the purpose of drying them and processing them into a pulpy mass; this is now also subjected to the above raw tallow, maceration in the Aluminiumchlorürlösung 10 ⁰ B.. After maceration for 24 hours, it is drained and the paste is exposed to cold pressing to remove the aqueous solution.

Bei der Verarbeitung von Rohtalg kann ein und dasselbe Aluminiumchlorürbad für eine ganze Reihe von Macerationen verwendet werden, sofern nur nach jedesmaligem Gebrauch die vom Rohtalg absorbirte Menge des Antisepts wieder ersetzt wird. Dagegen mufs bei den fetthaltigen Abfällen für jede neue Charge ein neues Bad bereitet werden, da die Menge der zur Einwirkung (sogenannten Tannirung erforderlichen Flüssigkeit von io° B. gerade dem Volumen entspricht, welches eine vollständige Imprägnation des Breies herbeiführt. Die beim Ablaufenlassen bezw. dem kalten Pressen des ■macerirten Breies zurückgewonnene Flüssigkeit kann zum Waschen des Rohmaterials vor seiner Zerkleinerung dienen, um so den noch in ihr verbliebenen kleinen Rest tannirenden Mittels auszunutzen.When processing raw tallow, one and the same aluminum chlorine bath can be used for one a whole series of macerations can be used, provided that the the amount of antiseptic absorbed by the raw tallow is replaced. On the other hand, it must be with the fatty waste for each new batch a new bath must be prepared, as the amount of liquid of 10 ° B. just the volume required for action (so-called tanning) corresponds, which brings about a complete impregnation of the pulp. The at Drain or liquid recovered from the cold pressing of the macerated pulp can be used to wash the raw material before it is crushed, so that it is still in it to take advantage of the small remainder of the tannic agent.

Das Maceriren der Rohstoffe in antiseptischer Flüssigkeit nimmt denselben die Gährungsfähigkeit, so dafs es nicht mehr nöthig ist, sie unmittelbar zu verarbeiten, sie können vielmehr magazinirt werden, was, wie leicht ersichtlich, einen regelmäfsigen Tagesbetrieb sichert und im Falle nicht genügend vorhandenen Rohmaterials eine Einstellung des Betriebes so lange gestattet, bis sich wieder Rohmaterial in entsprechendem Vorrathe angesammelt hat.The maceration of the raw materials in antiseptic liquid robs them of their fermentation ability, so that it is no longer necessary to process them directly, they can rather are stored in a magazine, which, as can be easily seen, ensures regular daily operations and in the If there is not enough raw material available, operations may be ceased as long as until raw material has accumulated again in a corresponding supply.

Die Ausbeutung des wie vorstehend beschrieben präparirten Rohmaterials auf Speisetalg geschieht in folgender Weise:The exploitation of the raw material prepared as described above on edible tallow happens in the following way:

Der Brei wird nach dem Abtropfenlassen zur Erleichterung des Abfliefsens des ausschmelzen-After draining, the pulp is added to facilitate the drainage of the melted

Claims

the tallow mixed with chopped straw, namely ι pCt. for raw tallow and with 2 pCt. for waste pulp. The raw material is then spread out in a 15 to 20 cm high layer on an inclined hollow plate, which is heated to about 100 ° by means of steam. The layer is covered with a similar second plate, also hollow and to be heated by steam; the pressure exerted by this on its base must be at least 50 kg per meter of surface. As a result of the combined action of heat and pressure, the sebum flows out and is collected in a suitable vessel at the lower end of the inclined plate. At the beginning of the process only pure sebum flows off; in the course of this, however, with increasing pressure and increasing temperature, the flesh and tissues tannin and decompose with the separation of water, which in turn occurs at 850.degree. has a dissolving (gelatine-forming) effect on the tissue, so that a brown liquid runs off with the sebum, which solidifies to gelatine on cooling. As soon as it is noticed that there is only a small quantity of sebum left in the drain, the operation is interrupted, the residues are quickly placed in the sacks of a hot press, and a further quantity of sebum and gelatin is obtained. Instead of the press, a centrifugal machine could also be used, into which a jet of steam would be introduced. Almost dry cakes, consisting of the more or less decomposed pieces of tissue, straw and a very low fat content, result as pre-fleshed or centrifugal residues. These can be used for fattening pigs or for obtaining the last remnants of stearic and margaric acid by treatment with sulfuric acid or in other suitable ways. The advantages of the new method presented here over the old methods are evident:

1. in the production of a food tallow (artificial butter etc.) of excellent quality and first Melting as a result of avoiding unnecessarily high temperatures, which are particularly caused by influencing the flesh and fat tissue cause a mismatched coloration of the product, worsen its taste and, above all, destroy the smell of fresh fat The edible tallow must be preserved as one of its most valuable commercial properties;

2. ■ in the possibility of exploitation of all Types of fat without in any way causing decomposition of the substances accompanying them, as everyone Contact the same with water or steam is known, in the presence of which from a certain point on the use of sulfuric acid salts proved necessary has proven;

3. As a significant simplification of equipment and apparatus, as well as the necessary special ones Devices for discharging the waste fluids, which are also due to the application of an antiseptic in the preprocessing of the raw material to a high degree of their health hazardous Properties are deprived;

4. in the production of commercially viable gelatine and usable prepregs as By-products. .
