Bei den bisher gebräuchlichen Auslaugevorrichtungen gelangt das aus dem Auslaugegefäß e ablaufende und im Verdampfer d von dem ausgezogenen Stoffe abgeschiedene Lösungsmittel in Dampfform in den Kondensator k, wird dort stark abgekühlt und niedergeschlagen und fließt von dort in das Auslaugegefäß e zurück. Hierbei findet eine weit stärkere Abkühlung statt, als sie für dasIn the leaching devices that have been used up to now, the solvent flowing out of the leaching vessel e and separated from the extracted substances in the evaporator d reaches the condenser k, where it is strongly cooled and precipitated and from there flows back into the leaching vessel e. A much stronger cooling takes place here than it does for the
ίο Niederschlagen der Dämpfe erforderlich wäre; es entsteht also ein unnötiger Wärmeverlust, der im Verdamfer d und bei heißer Auslaugung schon im Auslaugegefäß e ersetzt werden muß.ίο precipitation of the vapors would be required; There is therefore an unnecessary loss of heat which has to be replaced in the evaporator d and, in the case of hot leaching, already in the leaching vessel e .
Um diesen Verlust zu vermeiden, wird nach der Erfindung noch ein zweiter Kondensator c in den Betrieb eingeschaltet, der lediglich durch natürliche Abkühlung, nötigenfalls mit einer künstlich vergrößerten Abkühlungsfläche, wirkt. Diese Abkühlung genügt vollständig, um die Dämpfe des Lösungsmittels niederzuschlagen. Das Kühlgefäß c steht außer mit dem Verdampfer d mit dem Auslaugegefäß e, in das das Lösungsmittel zurückfließt, und zur Vermeidung eines etwaigen Überdruckes mit dem Kondensator k in Verbindung. Durch entsprechende Absperrvorrichtungen wird während des Auslaugevorganges die Verbindung zwischen dem Verdampfer d und dem Kondensator k unterbrochen und dafür der erstgenannte mit dem Luftkühler c verbunden. Wenn am Schluß des Vorganges, während des Austreibens des Lösungsmittels durch Dampf, der Kondensator k in Benutzung kommt, wird der Luftkühler c ausgeschaltet.In order to avoid this loss, according to the invention, a second capacitor c is switched on, which acts only through natural cooling, if necessary with an artificially enlarged cooling surface. This cooling is completely sufficient to precipitate the solvent vapors. In addition to the evaporator d , the cooling vessel c is connected to the leaching vessel e, into which the solvent flows back, and to avoid any overpressure with the condenser k . Appropriate shut-off devices interrupt the connection between the evaporator d and the condenser k during the leaching process, and the former is connected to the air cooler c. If, at the end of the process, while the solvent is being driven off by steam, the condenser k comes into use, the air cooler c is switched off.
Die Wirkung des Kühlers c kann durch richtige Bemessung seiner Abkühlungsoberfläche dem Bedarf angepaßt werden. Beispielweise kann, wie Fig. 2 zeigt, durch das Innere ein Luftrohr mit Regelungsklappe c1 führen, so daß die abkühlende Wirkung auch während des Betriebes geregelt werden kann.The effect of the cooler c can be adapted to requirements by correctly dimensioning its cooling surface. For example, as shown in FIG. 2, an air pipe with control flap c 1 can lead through the interior, so that the cooling effect can also be controlled during operation.
