Description
Es sind Zerkleinerungsmaschinen für Nahrungsmittel u. dgl. bekannt, die ein von einem Elektromötor mit hoher Drehzahl angetriebenes Schneidwerkzeug besitzen, mittels dessen die Nahrungsmittel in kurzer Zeit zerkleinert werden können. Das Zerkleinerungswerkzeug, das abwechselnd in der einen oder entgegengesetzten Drehrichtung antreibbar sein kann, besitzt gewöhnlich mehrere Arme, deren Arbeitskanten als messerartige Schneiden ausgebildet sind. Die Erfindung beruht nun auf der Erkenntnis, daß zum Zerkleinern von festeren Nahrungsmitteln u. dgl., wie z. B. Kaffeebohnen, Hülsenfrüchte, Gewürzkörner usw., eine bessere und schnellere Zerkleinerung dann erreicht wird, wenn die Arbeitskanten des Zerkleinerungswerkzeuges nicht schneidenartig, sondern stumpf bzw. flächig ausgebildet sind, weil hierdurch mehr Teilchen mit Sicherheit getroffen und zertrümmert werden. Die Erfindung zeigt eine Zerkleinerungsmaschine, die so eingerichtet ist, daß mit ihr beide Behandlungsmethoden der Nahrungsmittel ohne weiteres durchgeführt werden können.There are grinding machines for food and the like. Known, a cutting tool driven by an electric motor at high speed have, by means of which the food can be chopped up in a short time. The shredding tool that alternates in one or the other Direction of rotation can be driven, usually has several arms whose working edges are designed as knife-like cutting edges. The invention is now based on the knowledge that for chopping solid foods and the like. B. coffee beans, Legumes, spice grains, etc., better and faster shredding then is achieved if the working edges of the shredding tool are not cut-like, rather, they are designed to be blunt or flat, because as a result, more particles are certain get hit and smashed The invention shows a shredding machine, which is arranged in such a way that with it both methods of treatment of food can easily be carried out.
Gemäß der Erfindung ist die Zerkleinerungsmaschine so ausgebildet, daß die Arbeitskanten des Zerkleinerungswerkzeuges in der einen Drehrichtung mit scharfen Schneidkanten und in der entgegengesetzten Drehrichtung mit stumpfen als Schläger wirkenden Kanten versehen sind: Der Antriebsmotor kann hierbei in an sich bekannter Weise in bezug auf die Drehrichtung umschaltbar eingerichtet sein, oder es kann auch ein Zwischengetriebe vorgesehen sein, mittels dessen die Drehrichtung des. Zerkleinerungswerkzeuges in der gewünschten Weise einsetzbar ist.According to the invention, the shredding machine is designed so that the working edges of the shredding tool in one direction of rotation with sharp cutting edges and in the opposite direction of rotation with blunt than Racket-acting edges are provided: The drive motor can in this case in itself be set up switchable in a known manner with respect to the direction of rotation, or an intermediate gear can also be provided, by means of which the direction of rotation Des. Comminution tool can be used in the desired manner.
In der Abbildung- ist ein Ausführungsbeispiel eines solchen Zerkleierungswerkzeuges, das nach den beiden Drehrichtungen in verschiedener Weise wirksam ist, in perspektivischer Ansicht dargestellt. Wie die Abbildung zeigt, besteht das Zerkleinerungswerkzeug aus einer scheibenförmigen Nabe i, die in der Mitte mit einem' Vierkantloch 2 versehen ist, mittels dessen es 'auf ;/der antreibenden Welle undrehbar befestigt werden kann. An.- der Nabe i sind die vier kreuzförmig angeordneten Arme 3, 4, 5 und 6 angebracht, deren Kanten in der einen Drehrichtung als scharfe, messerartige Schneidkanten 7 ausgebildet sind, während die bei der entgegengesetzten Drehrichtung des Schneidwerkzeuges wirksam werdenden .Arbeitskanten 8 stumpf und breitflächig ausgebildet sind. Läßt man die das Zerkleinerungswerkzeug tragende Welle in solcher Drehrichtung laufen, daß die scharfen Schneidkanten zur Wirkung kommen, so kann man eine solche Zerkleinerungsvorrichtung in der bisher üblichen Weise mit besonderem Vorteil zum Zerkleinern von weichen Nahrungsmitteln, wie z. B. Kartoffeln, Gemüse und Früchte verwenden, während nach Umschalten der Drehrichtung die Zerkleinerungsmaschine insbesondere zum schnellen und wirksamen Zerkleinern von festeren Teilchen, wie z. B. Kaffeebohnen, Hülsenfrüchten, Gewürzkörnern u. dgl., geeignet ist. Die Schneidkantender Arme 3, 4, 5 und 6 sind, wie die Abbildung zeigt, abwechselnd nach oben . und unten abgeschrägt, um zu vermeiden, daß bei der Behandlung von flüssigen Stoffen eine unerwünschte nach oben gerichtete Strömung in dem Arbeitsbehälter entsteht. In manchen Fällen können zu diesem Zweck sämtliche Schneidkanten nach oben gerichtet sein, um auf diese Weise eine von oben nach unten gerichtete Strömung im Arbeitsbehälter zu erzielen.In the picture is an embodiment of such a crushing tool, which is effective in different ways according to the two directions of rotation, in perspective View shown. As the picture shows, there is the shredding tool from a disc-shaped hub i, which is provided with a 'square hole 2' in the middle is, by means of which it 'can be non-rotatably attached to; / the driving shaft can. On the hub i are the four arms 3, 4, 5 and 6 arranged in a cross shape attached, the edges of which in the one direction of rotation as sharp, knife-like cutting edges 7 are formed, while those in the opposite direction of rotation of the cutting tool effective working edges 8 are blunt and formed over a wide area. Leaves the shaft carrying the shredding tool runs in such a direction of rotation, that the sharp cutting edges come into effect, one can use such a comminuting device in the usual way with particular advantage for crushing soft Foods such as B. use potatoes, vegetables and fruits while after Switching the direction of rotation of the shredder especially for fast and effective crushing of solid particles, such as. B. Coffee beans, legumes, Spice grains and the like., Is suitable. The cutting edges of arms 3, 4, 5 and 6 are as the illustration shows, alternately upwards. and beveled at the bottom to avoid that in the treatment of liquid substances an undesirable upward direction Flow is created in the working container. In some cases you can do this for this purpose all cutting edges must be directed upwards, in order to thus one from above to achieve downward flow in the working tank.
