Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung von Pflanzenölen nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for producing vegetable oils according to the preamble of claim 1.

Vorrichtungen der eingangs genannten Art werden z.B. zur Herstellung von kaltgepressten Pflanzenölen, wie Rapsöl, Sonnenblumenöl, Leinöl usw. eingesetzt. Sie weisen in der Regel eine Pressspindel in Art einer Extruderschnecke auf, die in einem entsprechenden Gehäuse angeordnet und durch einen geeigneten Motor angetrieben wird. Ein Problem der bekannten Pflanzenölpressen besteht darin, dass die Ölsaaten nur einmal abgepresst werden können, wodurch sich eine beschränkte Ausbeute ergibt.Devices of the type mentioned above are e.g. for the production of cold-pressed vegetable oils, such as rapeseed oil, sunflower oil, linseed oil, etc. used. They usually have a press spindle in the manner of an extruder screw, which is arranged in a corresponding housing and driven by a suitable motor. A problem of the known vegetable oil presses is that the oilseeds can be pressed only once, resulting in a limited yield.

Aufgabe der Erfindung ist es, eine Vorrichtung zur Herstellung von Pflanzenölen der eingangs genannten Art zu schaffen, die eine höhere Ausbeute ermöglicht.The object of the invention is to provide a device for the production of vegetable oils of the type mentioned, which allows a higher yield.

Diese Aufgabe wird durch eine Vorrichtung zur Herstellung von Pflanzenölen mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Weiterbildungen und vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a device for producing vegetable oils with the features of claim 1. Advantageous developments and advantageous embodiments of the invention are the subject of the dependent claims.

Die Besonderheit der erfindungsgemäßen Vorrichtung besteht darin, dass die Ölsaat im Kaltpressverfahren zweimal ausgepresst werden kann, wodurch eine höhere Ausbeute erzielbar ist. Die Kaltpressung stellt eine äußerst schonende Methode zur Pflanzenölherstellung dar, wobei ein naturbelassenes, hochwertiges Pflanzenöl ohne chemische Zusatzstoffe, Extraktions- und Lösungsmittel hergestellt werden kann. Im Gegensatz zu dem im Warmpressverfahren hergestellten Öl behält das im Kaltpressverfahren hergestellte Öl seine gesunden Inhaltsstoffe, wie Vitamine, essentielle Fettsäuren, Lecithin, Enzyme, Spurenelemente und Geschmacksstoffe. Der bei der Kaltpressung anfallende Presskuchen stellt ein hochwertiges Viehfutter ohne Zusatzstoffe dar.The peculiarity of the device according to the invention is that the oilseed can be pressed out twice in the cold press process, whereby a higher yield can be achieved. Cold pressing represents an extremely gentle method of vegetable oil production, whereby a natural, high-quality vegetable oil can be produced without chemical additives, extraction solvents and solvents. In contrast to the hot-pressed oil, the cold-pressed oil retains its healthy ingredients, such as vitamins, essential fatty acids, lecithin, enzymes, trace elements and flavorings. The resulting in the cold pressing press cake is a high-quality cattle feed without additives.

Durch die mit der erfindungsgemäßen Vorrichtung mögliche Zweitpressung kann je nach Ölgehalt der Ölsaat ein Abpressgrad von ca. 34 - 40% erzielt werden. Zudem sind nur noch kleine Mengen an Feststoffen in dem abgepressten Öl enthalten, was einen weiteren Vorteil der erfindungsgemäßen Vorrichtung darstellt. Für die Zweitpressung kann zweckmäßigerweise eine gesonderte Pressspindel mit einer eigenen Werkzeuggeometrie eingesetzt werden.By means of the second pressing possible with the device according to the invention, depending on the oil content of the oilseed, a degree of pressing of approximately 34-40% can be achieved. In addition, only contain small amounts of solids in the pressed-oil, which represents a further advantage of the device according to the invention. For the second pressing, it is expedient to use a separate press spindle with its own tool geometry.

Durch die Erstpressung kann z.B. ein vielseitig verwendbares, hochwertiges Speiseöl hergestellt werden. Das bei der zweiten Pressung gewonnene Öl kann als Futteröl verwendet werden, mit dem energiearme Futtermittel aufgebessert werden. Das mit der Vorrichtung gewonnene Öl ist auch zur Herstellung von Treibstoff geeignet. So kann z.B. ein mit der Vorrichtung gewonnenes Rapsöl durch Sedimentation und Filtration gereinigt und als umweltfreundlicher Treibstoff für pflanzenöltaugliche Motoren verwendet werden.By the first pressing, e.g. a versatile, high-quality cooking oil can be produced. The oil obtained during the second pressing can be used as feed oil, with which low-energy feed is improved. The oil obtained with the device is also suitable for the production of fuel. Thus, e.g. a rapeseed oil obtained with the device is purified by sedimentation and filtration and used as an environmentally friendly fuel for vegetable oil suitable engines.

In einer besonders zweckmäßigen Ausführungsform der Erfindung sind der Zufuhrkörper und der Presskörper hohlzylindrisch ausgeführt und können somit als Drehteile einfach hergestellt werden.In a particularly expedient embodiment of the invention, the supply body and the compact are hollow cylindrical and can thus be easily manufactured as turned parts.

Der Zufuhrkörper ist in zweckmäßiger Weise fest mit einem Lagergehäuse verbunden, in dem eine mit der Pressspindel drehfest verbundene Antriebswelle drehbar gelagert ist.The supply body is suitably fixedly connected to a bearing housing in which a rotatably connected to the press spindle drive shaft is rotatably mounted.

In einer weiteren vorteilhaften Ausführung erfolgt die Übertragung der Drehbewegung von der Antriebswelle auf die Pressspindel über einen sowohl in die Antriebwelle als auch die Pressspindel formschlüssig eingreifenden Verbindungsbolzen. Dadurch kann die Pressspindel bei Bedarf einfach ausgewechselt werden. Der Verbindungsbolzen dient gleichzeitig als Abscherbolzen, wodurch eine Überlastsicherung erreicht wird.In a further advantageous embodiment, the transmission of the rotational movement from the drive shaft to the press spindle via a form-fitting engaging both in the drive shaft and the press spindle connecting bolt. As a result, the press spindle can be easily replaced if necessary. The connecting bolt serves as a shear pin, whereby an overload protection is achieved.

Der Presskörper 7 ist über ein Gewinde 15 mit dem Zufuhrkörper 3 verschraubt. Der Zufuhrkörper 3 ist seinerseits durch mehrere Zylinderschrauben 30 mit einem Lagergehäuse 1 verschraubt. Über in Figur 2 dargestellte Sicherungsscheiben 34 sind die Zylinderschrauben 30 zur festen Verbindung von Lagergehäuse 1 und Zufuhrkörper 3 gesichert. Durch zwei weitere Zylinderschrauben 31 ist die aus dem Lagergehäuse 1 und dem Zuführkörper 3 gebildete Einheit an einem Grundrahmen 4 befestigt. Bei der gezeigten Ausführung ist der Grundrahmen 4 als BlechBiegeteil aus Edelstahl gefertigt. In dem Zufuhrkörper 3 ist eine rechteckige Zuführungsöffnung 16 für die Zuführung der Ölsaat vorgesehen. Auf die Zuführungsöffnung 16 ist ein Zuführtrichter 13 aufgesetzt, der an seinem unteren Ende einen zu der Zuführungsöffnung 16 passenden rechteckigen Austrittsquerschnitt aufweist. Der Zuführtrichter 13 ist auf den Zufuhrkörper 3 aufgeflanscht.The apparatus shown in Figures 1 and 2 for the production of vegetable oils contains a housing having a substantially hollow cylindrical supply body 3 and a connected thereto hollow cylindrical compact 7, in which a designed as an extruder screw press spindle 6 is rotatably arranged. The helical groove of the press spindle 6 has a forward, i. in the transport direction of the material to be pressed, decreasing cross-section, so that the goods during transport to the front is pressed. The compact 7 is screwed by a thread 15 to the supply body 3. The supply body 3 is in turn screwed by a plurality of cylinder screws 30 with a bearing housing 1. Lock washers 34 shown in Figure 2, the cylinder screws 30 are secured to the fixed connection of the bearing housing 1 and supply body 3. By two further cylinder screws 31, the unit formed from the bearing housing 1 and the feed body 3 is fixed to a base frame 4. In the embodiment shown, the base frame 4 is made as a sheet metal bent part made of stainless steel. In the supply body 3, a rectangular feed opening 16 for supplying the oilseed is provided. On the feed opening 16, a feed hopper 13 is mounted, which has at its lower end a matching to the feed opening 16 rectangular outlet cross-section. The feed hopper 13 is flanged onto the supply body 3.

Wie aus Figur 2 hervorgeht, ist in dem Lagergehäuse 1 eine Antriebswelle 4 über zwei Radiallager 22, 23 und ein Axiallager 24 drehbar gelagert. Das in Figur 2 linke Radiallager 22 wird innerhalb des Lagergehäuses 1 durch eine Verschlussscheibe 2 und einen Seegerring 25 gehalten. Das in Figur 2 rechte Radiallager 23 wird in Axialrichtung durch den Zufuhrkörper 3 fixiert. Zwischen dem Zuführkörper 3 und der Antriebswelle 4 ist ein Radialwellendichtring 26 vorgesehen. Die Antriebswelle 4 enthält eine innere Bohrung 17, in die ein Zapfen 18 der Pressspindel 6 ragt. Die Übertragung der Drehbewegung von der Antriebswelle 4 auf die Pressspindel 6 erfolgt über einen sowohl in die Antriebwelle 4 als auch die Pressspindel 6 formschlüssig eingreifenden Verbindungsbolzen 5, der als Abschersicherung dient. Bei der gezeigten Ausführung ist der Verbindungsbolzen 5 als Mehrkantbolzen mit einer Sollbruchstelle ausgeführt. Die Antriebswelle 4 weist einen vom Lagergehäuse 1 vorstehenden Antriebszapfen 19 mit einer Passfeder 27 auf. Der Antriebszapfen 19 steht in Eingriff mit einem in Figur 1 dargestellten Getriebemotor 36, durch den die Pressspindel 6 über die Abtriebswelle 4 angetrieben wird. Der Getriebemotor 36 ist über einen Steg 44 und eine Schraube 43 ebenfalls am Grundrahmen 4 befestigt.As is apparent from Figure 2, in the bearing housing 1, a drive shaft 4 via two radial bearings 22, 23 and a thrust bearing 24 is rotatably mounted. The left in Figure 2 radial bearing 22 is held within the bearing housing 1 by a shutter disc 2 and a snap ring 25. The right in Figure 2 radial bearing 23 is fixed in the axial direction by the supply body 3. Between the feed body 3 and the drive shaft 4, a radial shaft seal 26 is provided. The drive shaft 4 includes an inner bore 17 into which a pin 18 of the press spindle 6 protrudes. The transmission of the rotational movement from the drive shaft 4 to the press spindle 6 via a both in the drive shaft 4 and the press spindle 6 positively engaging connecting pin 5, which serves as a shear-off. In the embodiment shown, the connecting bolt 5 is designed as a polygonal bolt with a predetermined breaking point. The drive shaft 4 has a bearing housing 1 projecting drive pin 19 with a key 27 on. The drive pin 19 is in engagement with a gear motor 36 shown in Figure 1, through which the press spindle 6 is driven via the output shaft 4. The geared motor 36 is also secured to the base frame 4 via a web 44 and a screw 43.

Zur Vermeidung eines Überdrucks in Inneren des Lagergehäuses 1 sind an diesem zwei Überdruckventile angeordnet, die einen Ventilkörper 11 mit einer durch eine Druckfeder 29 beaufschlagten Kugel 28 enthalten. Durch diese Überdruckventile kann verhindert werden, sich aufgrund eines über Schmiernippel 35 den Lagern zugeführten Schmiermittels ein zu starker Druck im Inneren des Lagergehäuses 1 aufbaut.To avoid an overpressure in the interior of the bearing housing 1, two overpressure valves are arranged on this, which contain a valve body 11 with a ball 28 acted upon by a compression spring 29. By means of these pressure relief valves, an excessively high pressure in the interior of the bearing housing 1 can be prevented due to a lubricant supplied to the bearings via lubricating nipple 35.

Im vorderen Bereich des Presskörpers 7 sind über dessen Umfang verteilte radiale Austrittsöffnungen 33 für das Öl vorgesehen. Im Bereich der Austrittsöffnungen 33 ist der Außendurchmesser der Pressspindel 6 reduziert, so dass das ausgepresste Öl zurückfließen kann. Rechts und links von den Austrittsöffnungen 33 weist der Presskörper 7 an seiner Außenseite radial vorstehende, umlaufende Abtropfnasen 42 auf. An der Innenseite des in Figur 2 rechten vorderen Endes des hohlzylindrischen Presskörpers 7 sind zahnförmige Vertiefungen 38 eingearbeitet. Durch diese Vertiefungen 38 wird ein Mitdrehen des Pressgutes zum Aufbau des für ein Vorquetschen erforderlichen Gegendrucks verhindert. Auf ein Außengewinde am vorderen Ende des Presskörpers 7 ist ferner eine Verbindungshülse 8 aufgeschraubt. In diese ist ein über ein Gewinde axial verstellbarer und durch eine Kontermutter 10 fixierbarer Presskopf 9 mit einer Durchgangsbohrung 39 eingeschraubt. Durch Verstellung des Presskopfs 9 kann der Spalt zwischen der vorderen Stirnseite des Presszylinders 7 und der dieser zugewandeten Stirnfläche des Presskopfs 9 eingestellt werden. An seiner der Pressspindel 6 zugewandten Stirnfläche enthält der Presskopf 9 auch zahnförmige Vertiefungen 40, durch die ebenfalls das Mitdrehen des Pressgutes verhindert wird. In den Presskopf 9 ist eine Pressdüse 12 mit einer sich nach vorne verengenden Durchgangsöffnung 41 eingeschraubt. Auf dem vorderen Ende des Presskopfs 9 ist ein Cracker 37 befestigt, durch den das aus der Pressdüse 12 austretende Gut gebrochen wird.In the front region of the compact 7 distributed over the circumference radial outlet openings 33 are provided for the oil. In the region of the outlet openings 33, the outer diameter of the press spindle 6 is reduced, so that the squeezed oil can flow back. Right and left of the outlet openings 33, the pressing body 7 on its outer side on radially projecting, surrounding drip-offs 42. On the inside of the right in Figure 2 front end of the hollow cylindrical compact 7 tooth-shaped recesses 38 are incorporated. By these recesses 38 co-rotation of the material to be pressed to build up the required back pressure for a counterpressure is prevented. On an external thread at the front end of the compact 7, a connecting sleeve 8 is further screwed. In this an axially adjustable by a thread and fixable by a lock nut 10 pressing head 9 is screwed with a through hole 39. By adjusting the pressing head 9, the gap between the front end face of the pressing cylinder 7 and the facing end face of the pressing head 9 can be adjusted. At its end face facing the press spindle 6, the press head 9 also contains tooth-shaped depressions 40, which also prevent the co-rotation of the pressed material. In the pressing head 9, a pressing nozzle 12 is screwed with a forward narrowing passage opening 41. On the front end of the pressing head 9, a cracker 37 is attached, through which the emerging from the pressing nozzle 12 Good is broken.

Der Zufuhrkörper 3, der Grundrahmen 4 und der Zuführtrichter 13 sind zweckmäßigerweise aus Edelstahl gefertigt. Die Pressspindel 6, der Presskopf 9 und der Presszylinder 7 sind aus hochwertigem, gehärtetem Werkzeugstahl hergestellt.The feed body 3, the base frame 4 and the feed hopper 13 are suitably made of stainless steel. The press spindle 6, the pressing head 9 and the pressing cylinder 7 are made of high-quality, hardened tool steel.

Mit der vorstehend beschrieben Vorrichtung wird das über den Zuführtrichter 13 zugeführte Pressgut von der durch den Getriebemotor 36 angetriebenen Pressspindel 6 nach vorne in Richtung des Presskopfs 9 transportiert und dabei gepresst. Das dadurch herausgepresste Öl kann durch die Öffnungen 33 im vorderen Bereich des Presskörpers 7 austreten und an den Abtropfnasen 42 abtropfen. Der verbleibende Presskuchen wird durch den zwischen der vorderen Stirnseite der Pressspindel 6 und der inneren Stirnfläche des Presskopfs 9 gebildeten Spalt und die Durchgangsbohrungen 39 und 41 des Presskopfs 9 bzw. der Pressdüse 12 nach außen gedrückt und durch den Cracker 37 in kleinere Teile gebrochen.With the apparatus described above, the material to be fed via the feed hopper 13 is transported forward by the press spindle 6 driven by the geared motor 36 in the direction of the press head 9, thereby being pressed. The resulting oil pressed out can escape through the openings 33 in the front region of the compact 7 and drip on the Abtropfnasen 42. The remaining press cake is pushed outward by the gap formed between the front end face of the press spindle 6 and the inner end face of the press head 9 and the through holes 39 and 41 of the press head 9 and the press nozzle 12, respectively, and broken into smaller pieces by the cracker 37.
