KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Kühlern für Molkerei- und andere Zwecke ist es eine Hauptsache, dafs dieselben so schnell wie irgend möglich wirken, d.h. dafs die Abkühlung der Flüssigkeit in möglichst kurzer Zeit vor sich geht.In the case of coolers for dairy and other purposes, it is an important thing that they do so act as quickly as possible, i.e. that the liquid should be cooled down as quickly as possible a short time is going on.
Dieser Erfolg soll durch den im Nachstehenden beschriebenen und in der beiliegenden Zeichnung dargestellten Kühler erreicht werden. Derselbe ist besonders für die Vacuumkühlmaschine gebaut; die Kälte wird .also durch Verdunsten einer Salzlösung im luftverdünnten Raum in dem Kühler selbst erzeugt. This success is said to be achieved by the one described below and in the enclosed Drawing shown cooler can be achieved. The same is especially true for the vacuum chiller built; the cold is .so by evaporation of a salt solution in the air-diluted Space created in the cooler itself.
Der Kühler besitzt, wie aus den Fig. 1 und 2 hervorgeht, in der Hauptsache eine kegelförmige Gestalt und besteht ' aus drei kegelförmigen Stücken, nämlich aus dem den Boden bildenden, oben durch eine Kugelcalotte abgeschlossenen Hohlkegel A und dem äufseren, die Oberfläche bildenden Kegelmantel B, dessen Spitze durch einen Dom gebildet wird, von dem - der Anschlufsstutzen an die Kühlmaschine α abzweigt. Zwischen dem äufseren Mantel und dem Boden befindet sich ein dritter Kegelmantel D, welcher dazu dient, einen geregelten Umlauf in dem Apparat zu ermöglichen. Der Dom C besitzt an einer Seite ein Schauglas, um die Höhe des Flüssigkeitsstandes in dem Apparat beobachten zu können, während der Kegelmantel B auf seiner Oberfläche einen kegelspiralförmigen Kanal besitzt, welcher dazu dient, die zu kühlende Flüssigkeit langsam an dem Kegelmantel herunterzuleiten, so dafs dieselbe in der dazu erforderlichen Zeit gekühlt wird.The cooler has, as can be seen from FIGS. 1 and 2, mainly a conical shape and consists of three conical pieces, namely the hollow cone A , which forms the bottom and is closed at the top by a spherical calotte, and the outer conical envelope, which forms the surface B, the tip of which is formed by a dome, from which - the connection piece to the cooling machine α branches off. Between the outer jacket and the bottom there is a third conical jacket D, which is used to enable regulated circulation in the apparatus. The dome C has a sight glass on one side in order to be able to observe the height of the liquid level in the apparatus, while the surface of the cone jacket B has a conical spiral-shaped channel which is used to slowly guide the liquid to be cooled down the cone jacket, so that the same is cooled in the time required for this.
Das Innere des Apparates ist nun bis zur Mitte des Schauglases b mit irgend einer schwer gefrierenden Salzlösung gefüllt, welche unter der Wirkung der Luftleere heftig verdampft und sich daher stark abkühlt.The interior of the apparatus is now filled up to the middle of the sight glass b with some kind of hard-to-freeze salt solution which, under the effect of the vacuum, vaporizes violently and therefore cools down considerably.
Unterdessen wird die zwischen dem Kegel-. mantel B und D befindliche Salzlösung, welche mit der warmen Milch oder dergleichen in Berührung steht und daher leichter ist als die abgekühlte Salzlösung, in dem Zwischenraum zwischen D und B nach oben steigen. Es tritt also ein Umlauf in Richtung der in der Figur angegebenen Pfeile ein. Derselbe kann jedoch noch dadurch beschleunigt werden, dafs ein Rührwerk, wie das in Fig. 1 dargestellte, welches aus einer senkrechten, durch Frictionsvorgelege angetriebenen Welle mit Rührschräube besteht, angeordnet ist.Meanwhile, the one between the cone. Coats B and D located saline solution, which is in contact with the warm milk or the like and is therefore lighter than the cooled salt solution, rise in the space between D and B to the top. There is therefore a rotation in the direction of the arrows indicated in the figure. It can, however, be accelerated by arranging a stirrer like the one shown in FIG. 1, which consists of a vertical shaft with a stirrer screw driven by friction gears.
Der Blechteller c und der Ringkegel d sollen verhindern, dafs das durch Aufspritzen der Kühlflüssigkeit emporgeschleuderte Wasser bezw. Salz mit in die Luftpumpenleitung gerissen wird.The tin plate c and the annular cone d are intended to prevent the water or water thrown up by the spray of the cooling liquid from being thrown up. Salt is dragged into the air pump line.
Der ganze Apparat steht auf Füfsen f und besitzt aufserdem einen Ablafs- bezw. Einlafshahn e. Die zu kühlende Flüssigkeit, Milch oder dergleichen, tritt bei I ein und verläfst durch die Auslauftülle bei II den Apparat, von wo sie in ein daruntergestelltes Gefäfs fliefst. Es wird auf diese Weise in dem Kühler das Gegenstromprincip voll zur Geltung gebracht,The whole apparatus stands on feet f and also has a drain or Inlet tap e. The liquid to be cooled, milk or the like, enters at I and leaves the apparatus through the spout at II, from where it flows into a vessel placed below. In this way, the countercurrent principle is brought to full advantage in the cooler,
was bisher bei Vacuummaschinen nicht möglich war.which was previously not possible with vacuum machines.
