5 Materials.5 materials.
Extrudierte Nahrungsmittel, die als Stange mit irgendeiner Kontur aus dem Düsenkopf des Extruders austreten, sind weit verbreitet. Nach dem Austritt aus der Düse wird das Extrudat in der gewünschten Länge mittels einer Schneid¬ vorrichtung abgeschnitten, um anschließend verpackt und beispielsweise als Snack in den Handel gebracht zu werden.Extruded foods that emerge from the extruder die head as a rod with any contour are common. After exiting the die, the extrudate is cut off in the desired length by means of a cutting device in order to be subsequently packaged and, for example, to be marketed as a snack.
Der Erfindung liegt die Aufgabe zugrunde, eine Extrudier- 5 Vorrichtung mit einer universell einsetzbaren Schneid¬ einrichtung zu schaffen, mit welcher auch eine Formgestaltung des Extrudats möglich ist.The invention has for its object to provide an extrusion device with a universally applicable cutting device, with which a shape of the extrudate is also possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an Q dem Düsenkopf eine Schneidklinge drehbar gelagert ist, und daß die Schneidklinge an der Düsenöffnung vorbeigeführt ist. Je nach Drehgeschwindigkeit der Schneidklinge kann das Extrudat kürzer oder länger abgeschnitten werden.This object is inventively achieved in that at Q to the nozzle head, a cutting blade is rotatably mounted, and that the cutting blade is moved past the nozzle opening. Depending on the speed of rotation of the cutting blade, the extrudate can be cut shorter or longer.
5 Gemäß einer bevorzugten Ausführungsform ist die Schneid¬ klinge an einer Achse befestigt und die Achse ist über Lager in wenigstens einem an dem Düsenkopf befestigten Lager¬ schild gehalten. Für den Drehantrieb der Achse ist gemäß einer bevorzugten Ausführungsform ein Zahnrad drehfest an Q der Achse angeordnet und der Drehantrieb erfolgt über einen Zahnriemen, der in das Zahnrad eingreift.According to a preferred embodiment, the cutting blade is fastened to an axis and the axis is held via bearings in at least one bearing plate fastened to the nozzle head. According to a preferred embodiment, for the rotary drive of the axis, a gearwheel is arranged in a rotationally fixed manner on the axis Q and the rotary drive takes place via a toothed belt which engages in the gearwheel.
In weiterer Ausgestaltung können zwei oder mehr Schneid¬ klingen verteilt über den Umfang an dem Düsenkopf angeordnet sein. Dabei kann eine Schneidklinge die gesamte Düsenöffnung überstreichen und die andere Schneidklinge bzw. die anderen Schneidklingen können die Düsenöffnung nur an der Peripherie überstreichen, so daß mittels dieser Schneidklingen nur ein Einschneiden an dem Extrudat erfolgt. Dadurch ist es möglich, daß infolge der Expansion des Ex- trudates nach dem Austritt aus dem büsenkopf (infolge des Druckabfalls entweicht die in dem Extrudat enthaltene Flüssigkeit als Dampf bei gleichzeitigem Aufquellen des Extrudates) eine gezielte Oberflächenstrukturierung des Extrudates geschaffen wird. Beispielsweise kann bei einem Extrudat mit den Umrissen eines Tieres an dem Bereich eingeschnitten werden, der die Beine darstellt, so daß nach der Expansion vier Beine an der Unterseite des Tieres er¬ sichtlich sind. Bei entsprechender Einstellung der ein¬ schneidenden und der abschneidenden Klingen und der Auswahl des Einschneidbereiches können im Endzustand plastisch ge¬ formte Extrudatabschnitte geschaffen werden.In a further embodiment, two or more cutting blades can be arranged distributed over the circumference on the nozzle head. In this case, one cutting blade can sweep over the entire nozzle opening and the other cutting blade or the other cutting blades can only sweep over the nozzle opening at the periphery, so that by means of this Cutting blades only cut into the extrudate. As a result, it is possible that as a result of the expansion of the extrudate after leaving the die head (due to the drop in pressure, the liquid contained in the extrudate escapes as steam while the extrudate swells at the same time) a targeted surface structuring of the extrudate is created. For example, in the case of an extrudate, the outline of an animal can be cut in the area which represents the legs, so that after the expansion four legs can be seen on the underside of the animal. With the corresponding setting of the cutting and cutting blades and the selection of the cutting area, plastically shaped extrudate sections can be created in the final state.
Gemäß einer bevorzugten Ausführungsform sind vier kreuz¬ förmig angeordnete Schneidklingen vorgesehen, die an den Achsen der Schneidklingen angeordneten Zahnräder sind über Zahnriemen miteinander verbunden und an der Achse einer Schneidklinge ist ein zweites Zahnrad vorgesehen, welches über einen Zahnriemen mit einem Antriebsmotor verbunden ist. Durch diese Anordnung wird eine synchrone Bewegung der Schneidklingen gewährleistet, so daß das aus der Düse aus¬ tretende Extrudat immer im vorbestimmten Zeitpunkt einge- schnitten bzw. abgeschnitten wird.According to a preferred embodiment, four cruciform cutting blades are provided, the gear wheels arranged on the axes of the cutting blades are connected to one another via toothed belts and a second gear wheel is provided on the axis of a cutting blade, which is connected to a drive motor via a toothed belt. This arrangement ensures a synchronous movement of the cutting blades, so that the extrudate emerging from the nozzle is always cut or cut at the predetermined time.
Gemäß einer weiteren bevorzugten Ausführungsform ist ah dem Düsenkopf ein Drehring angeordnet und an dem Drehring ist eine radial zur Düsenöffnung gerichtete Schneidklinge befestigt. Dabei können auch mehrere Schneidklingen über den Umfang verteilt an dem Drehring angeordnet sein. Mit dieser Anordnung ist es beispielsweise möglich, ein stangen- förmiges Extrudat derart einzuschneiden, daß sich eine schraubenförmige Gestalt mit ein oder mehreren Gängen ergibt.According to a further preferred embodiment, a rotating ring is arranged behind the nozzle head and a cutting blade directed radially to the nozzle opening is fastened to the rotating ring. Several cutting blades can also be arranged on the rotating ring distributed over the circumference. With this arrangement it is possible, for example, to cut a rod-shaped extrudate in such a way that a helical shape with one or more passages results.
Zwischen dem Drehring und dem Düsenkopf ist vorzugsweise ein Lager angeordnet und der Drehring ist an der Außenseite mit einer Umfangsnut zur Aufnahme eines Treibriemens aus¬ gebildet.A bearing is preferably arranged between the rotating ring and the nozzle head and the rotating ring is on the outside formed with a circumferential groove for receiving a drive belt.
Zur Ausbildung beispielsweise zweier gegenläufiger Schrauben- linien an der Außenseite eines stangenförmigen Extrudates können vorzugsweise zwei gegenläufige Drehringe mit Schneid¬ klingen angeordnet sein.To form, for example, two counter-rotating screw lines on the outside of a rod-shaped extrudate, two counter-rotating rings with cutting blades can preferably be arranged.
In Weiterbildung der Erfindung können die Schneidklingen radial und/oder axial einstellbar zum Düsenkopf vorgesehen sein, so daß insbesondere die Einschnittiefe der richt- durchschneidenden Klingen gesteuert werden kann.In a further development of the invention, the cutting blades can be provided such that they can be adjusted radially and / or axially to the nozzle head, so that in particular the cutting depth of the blades that cut through can be controlled.
Ausführungsbeispiele der Erfindung werden anhand der nach- stehenden Zeichnung näher erläutert. Es zeigt:Exemplary embodiments of the invention are explained in more detail with reference to the drawing below. It shows:

Fig. 1 zeigt eine Vorderansicht auf einen Düsenkopf 10 eines Nahrungsmittelextruders. Der Düsenkopf 10 weist eine ringförmige Düse 12 auf, die durch die Innenbohrung der Platte 14 und den Mantel eines Dornes 16 begrenzt wird. Über den Umfang der Außenseite des Düsenkopfes 10 verteilt sind Lageranordnungen 18, 20, 24 und 26 für an diesen Lageranordnungen an Drehachsen 2 _^___^._ß2 fcund 34 befestigte Schneidklingen 36, 38, 40 und 42. An der Achse 28 ist ein Zahnrad 44, an der Achse 30 ein Zahnrad 46, an der Achse 32 ein Zahnrad 48 und an der Achse 34 ein Zahnrad 50 dreh¬ fest angeordnet. Über die Zahnräder 44, 46, 48 und 50 ist ein Zahnriemen 52 geführt, so daß die Zahnräder und damit die Achsen und die daran befestigten Schneidklingen synchron umlaufen. Der Antrieb der Schneidklingen erfolgt über einen Zahnriemen 54, der zwischen einem auf der Achse 32 drehfest angeordneten Zahnrad 56 und einem nicht dargestellten An- • triebsaggregat angeordnet ist.1 shows a front view of a nozzle head 10 of a food extruder. The nozzle head 10 has an annular nozzle 12 which is limited by the inner bore of the plate 14 and the jacket of a mandrel 16. Distributed over the circumference of the outside of the nozzle head 10 are bearing arrangements 18, 20, 24 and 26 for cutting blades 36, 38, 40 and 42 attached to these bearing arrangements on axes of rotation 2 _ ^ ___ ^ ._ ß 2 fc and 34 a gear 44, on the axis 30 a gear 46, on the axis 32 a gear 48 and on the axis 34 a gear 50 rotatably arranged. A toothed belt 52 is guided over the toothed wheels 44, 46, 48 and 50, so that the toothed wheels and thus the axes and the cutting blades attached to them rotate synchronously. The cutting blades are driven by a toothed belt 54 which is non-rotatable between one on the axis 32 arranged gear 56 and a not shown check • is disposed drive unit.
Aus Fig. 2 ist ersichtlich, daß jede Lageranordnung 18, 20, 24 und 26 aus zwei an der Außenseite des Düsenkopfes 10 befestigten Lagerschildern 60, 62, 64, 66 besteht. Die Achse 28 ist in dem Lagerschild 20 über ein Wälzlager 68 und in dem Lagerschild 62 über ein Wälzlager 70 gelagert. Eine entsprechende Lagerung der Achsen ist in den anderen Lageranordnungen ausgebildet. In Fig. 2 ist das vordere Ende einer Extruderschnecke 72 angedeutet, mit deren Hilfe das zu extrudierende Material aus dem Düsenkopf gepreßt wird.From Fig. 2 it can be seen that each bearing assembly 18, 20, 24 and 26 consists of two bearing plates 60, 62, 64, 66 attached to the outside of the nozzle head 10. The axis 28 is supported in the end shield 20 via a roller bearing 68 and in the end shield 62 via a roller bearing 70. A corresponding bearing of the axes is formed in the other bearing arrangements. In Fig. 2 the front end of an extruder screw 72 is indicated, by means of which the material to be extruded is pressed out of the die head.
Aus Fig. 1 ist ersichtlich, daß die Schneidklinge 36 über die ganze Düsenöffnung 12 geführt ist, so daß bei einem Vorbeigang dieser Schneidklinge an der Öffnung der aus¬ tretende Extruderstrang abgeschnitten wird. Die Schneid¬ klingen 38, 40 und 42 sind kürzer, so daß bei einem Ver¬ schwenken der Klinge 38 um 90°, der Klinge 40 u d 180° und der Klinge 42 um 270° in Uhrzeigerrichtung lediglich das aus der Düsenöffnung austretende Extrudat an der Außenseite angeschnitten wird. Infolge der beim Austreten des Extrudates auftretenden Expansion kann dann eine gewünschte Oberflächen.- formung des Extrudates erfolgen.From Fig. 1 it can be seen that the cutting blade 36 is guided over the entire nozzle opening 12, so that when this cutting blade passes the opening, the extruder strand emerging is cut off. The cutting blades 38, 40 and 42 are shorter, so that when the blade 38 is pivoted by 90 °, the blade 40 and 180 ° and the blade 42 by 270 ° in the clockwise direction, only the extrudate emerging from the nozzle opening on the Is cut on the outside. As a result of the expansion occurring when the extrudate emerges, a desired surface shaping of the extrudate can then take place.
Fig. 3 zeigt eine Draufsicht auf einen Düsenkopf 80 mit einer ringförmigen Düse 82, in deren Mitte ein Dorn 84 ange¬ ordnet ist. An der Außenseite 86 des Düsenkopfes 80 ist ein Drehring 88 über ein Wälzlager 90 angeordnet. An der Vorder- seite des Drehringes 88 sind zwei Schneidklingen 92, 94 angeordnet. Dazu sind an dem Drehring 88 Zapfen 96, 98 befestigt, an welchen Laschen 100, 102 vorgesehen sind, in welchen der Schaft 104 bzw. 106 der Klinge 92 bzw. 94 ein¬ gespannt sind. Nach Lösen von Schrauben 108 bzw. 110 können die Klingen 92 bzw. 94 in ihrem Abstand zu der Düsenöffnung 82 radial verschoben werden. Wie aus Fig. 2 zu ersehen ist, können die Schäfte 96 bzw. 98 axial an dem Drehring 88 ein¬ gestellt werden, so daß der Abstand der Klingen 92 und 94 zu der Düsenöffnung 82 einstellbar ist. Aus Fig. 4 ist andeutungsweise das vordere Ende einer ExtruderSchnecke 112 zu sehen. An dem Drehring 88 sind zwei Klingen angeordnet, jedoch wäre es möglich, mehrere Klingen vorzusehen. Eben¬ falls wäre es möglich, einen zweiten Drehring an der Außen¬ seite des Düsenkopfes anzuordnen und diesen Drehring ent¬ gegengesetzt zu dem Drehring 88 anzutreiben, so daß durch Anschneiden der Außenseite des extrudierten Stranges gegen¬ läufige Gewindegänge ausgebildet werden können.3 shows a top view of a nozzle head 80 with an annular nozzle 82, in the center of which a mandrel 84 is arranged. On the outside 86 of the nozzle head 80, a rotating ring 88 is arranged via a roller bearing 90. Two cutting blades 92, 94 are arranged on the front side of the rotary ring 88. For this purpose, pins 96, 98 are attached to the rotary ring 88, on which tabs 100, 102 are provided, in which the shafts 104 and 106 of the blades 92 and 94 are clamped. After loosening screws 108 and 110, the blades 92 and 94 can be radially displaced in their distance from the nozzle opening 82. As can be seen from FIG. 2, the shafts 96 and 98 can be adjusted axially on the rotary ring 88 so that the distance between the blades 92 and 94 to the nozzle opening 82 is adjustable. 4, the front end of an extruder screw 112 can be seen. Two blades are arranged on the rotating ring 88, but it would be possible to provide several blades. It would also be possible to arrange a second rotating ring on the outer side of the die head and to drive this rotating ring in the opposite direction to the rotating ring 88, so that counter threads can be formed by cutting the outside of the extruded strand.
