Description

Die Erfindung betrifft eine Vorrichtung zum Flockieren oder Schroten von Speisegetreide nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for flaking or grinding food crops according to the preamble of claim 1.

Aus der CH 697 410 B1 ist eine gattungsgemäße Vorrichtung zur Herstellung von Flocken aus Getreide bekannt. Diese weist zwei zueinander parallele und innerhalb eines Gehäuses durch einen Spalt voneinander getrennt angeordnete, motorisch drehbare Flockierwalzen auf.From the CH 697 410 B1 a generic device for the production of flakes from cereals is known. This has two motor-rotatable flocculating rollers which are arranged parallel to one another and are separated from one another within a housing by a gap.

Die DE 1 054 809 B offenbart einen Walzenstuhl, der zwei innerhalb eines Gehäuses drehbar gelagerte und durch einen Spalt voneinander getrennte Mahlwalzen enthält. Im Einlaufbereich der beiden Mahlwalzen sind innerhalb des Gehäuses zwei Speisewalzen angeordnet. Eine oberhalb eines Abstreifers an den Mahlwalzen angeordnete Absaugvorrichtung dient zur Abführung des durch die Walzenoberflächen mitgeführten Luftstroms, der von dem mit der Mahlwalze in Berührung gelangenden oder dieser dicht gegenüberstehenden Abstreifer aufgefangen wird. Dadurch soll erreicht werden, dass der Luftstrom den Mahlgutstrom zum Mahlspalt nicht behindert.The DE 1 054 809 B discloses a roller mill that contains two grinding rollers rotatably mounted within a housing and separated from one another by a gap. Two feed rollers are arranged inside the housing in the inlet area of the two grinding rollers. A suction device arranged above the scraper on the grinding rollers serves to discharge the air flow carried through the roller surfaces, which is caught by the scraper which comes into contact with the grinding roller or is located opposite it. This is to ensure that the air flow does not hinder the material flow to the grinding gap.

Ein Problem bekannter Vorrichtungen zum Flockieren oder Schroten von Speisegetreide besteht darin, dass bei der Bearbeitung des Speisegetreides Staub entsteht, der zu Störungen des Bearbeitungsprozesses und zu Beeinträchtigungen der Bearbeitungsqualität führen kann.A problem with known devices for flocculating or grinding food crops is that the processing of the food crop produces dust which can lead to disruptions in the processing process and impairment of the processing quality.

Aufgabe der Erfindung ist es, eine Vorrichtung zum Flockieren oder Schroten zu schaffen, die eine möglichst effektive und staubfreie Behandlung des Speisegetreides ermöglicht.The object of the invention is to provide a device for flaking or crushing, which enables the most effective and dust-free treatment of the food grain.

Diese Aufgabe wird durch eine Vorrichtung zum Flockieren oder Schroten mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a device for flaking or grinding with the features of claim 1. Expedient refinements and advantageous developments of the invention are specified in the subclaims.

Bei der erfindungsgemäßen Vorrichtung zum Flockieren oder Schroten ist an das Gehäuse mit den zwei zueinander parallelen und innerhalb des Gehäuses durch einen Spalt voneinander getrennt angeordneten, motorisch drehbaren Walzen eine Absaugeinrichtung zur Erzeugung einer über die Sammel- und Abführeinrichtung von unten angesaugten und entlang der Außenseite der Walzen nach oben führenden Ansaugluft angeschlossen. Die Sammel- und Abführeinrichtung weist einen Auffangtrichter und ein in einen Sammelbehälter führendes Austrittsrohr auf. Das Austrittsrohr kann in der Höhe verstellbar sein. Durch die Absaugeinrichtung kann der bei der Bearbeitung des Getreides entstehende Staub zur Oberseite des Gehäuses geleitet und aus dem Gehäuse abgeführt werden. Auf diese Weise kann eine staubfreie Bearbeitung erfolgen. Der Staub wird über die Absaugeinrichtung nach oben abgesaugt, während das zwischen den Walzen bearbeitete Getreide nach unten fällt und an der Unterseite des Gehäuses abgeführt werden kann. Durch den über die Absaugeinrichtung erzeugten Unterdruck im Gehäuse kann außerdem die Entstehung von Schwitzwasser und die dadurch bedingte Bildung von Schimmel verhindert werden. Dadurch wird eine besonders hygienische Bearbeitung ermöglicht.In the device according to the invention for flaking or crushing, a suction device for generating is provided on the housing with the two motor-rotatable rollers which are parallel to one another and separated from one another within the housing by a gap an intake air which is sucked in from the bottom via the collecting and discharge device and leads upward along the outside of the rollers. The collection and discharge device has a collecting funnel and an outlet pipe leading into a collection container. The height of the outlet pipe can be adjusted. The dust generated during the processing of the grain can be guided to the top of the housing and removed from the housing by the suction device. In this way, dust-free processing can take place. The dust is sucked up by the suction device, while the grain processed between the rollers falls down and can be removed at the bottom of the housing. The negative pressure in the housing generated by the suction device can also prevent the formation of condensation water and the resulting formation of mold. This enables particularly hygienic processing.

In einer besonders vorteilhaften Ausführung enthält die Absaugvorrichtung einen Staubsauger und eine Ansaugleitung mit zwei oberhalb der beiden Walzen in das Gehäuse einmündenden Ansaugstutzen. Dadurch kann der Staub besonders effektiv abgesaugt werden. In der Ansaugleitung kann zweckmäßigerweise ein Drosselventil angeordnet sein. Dadurch kann die Absaugleistung eingestellt und dadurch der Feinmehlanteil im bearbeiteten Getreide verändert werden. Es kann somit auch ein Windsichten durchgeführt werden.In a particularly advantageous embodiment, the suction device contains a vacuum cleaner and a suction line with two suction nozzles opening into the housing above the two rollers. This allows the dust to be extracted particularly effectively. A throttle valve can expediently be arranged in the intake line. This allows the suction power to be adjusted and the fine flour content in the processed grain to be changed. A wind sighting can thus also be carried out.

In einer weiteren vorteilhaften Ausgestaltung kann an dem Gehäuse eine Stelleinrichtung zur Einstellung des Spalts zwischen den beiden Walzen angeordnet sein. Dadurch kann die Größe bzw. Form der Flocken oder geschroteten Körner eingestellt werden.In a further advantageous embodiment, an adjusting device for adjusting the gap between the two rollers can be arranged on the housing. This allows the size or shape of the flakes or crushed grains to be adjusted.

Innerhalb des Gehäuses können oberhalb des zwischen den beiden Walzen gebildeten Spalts entgegengesetzt schräge Leitbleche angeordnet sein. Durch diese Leitbleche kann das über die Einspeise- oder Dosiereinrichtung zugeführte Speisegetreide einerseits zu dem Spalt gelenkt werden, andrerseits werden durch diese Leitbleche die Ansaugstutzen abgeschirmt und verhindert, dass das über die Einspeise- oder Dosiereinrichtung zugeführte Speisegetreide noch vor der Bearbeitung über die Ansaugstutzen angesaugt wird.Opposite oblique guide plates can be arranged inside the housing above the gap formed between the two rollers. By means of these guide plates, the feed grain fed via the feed or metering device can be directed to the gap on the one hand, and on the other hand, the intake ports are shielded by these guide plates and prevent the feed grain fed via the feed or metering device from being sucked in via the intake port before processing ,

Unterhalb des zwischen den beiden Walzen gebildeten Spalts können innerhalb des Gehäuses außerdem zwei an den Walzen anliegende und einstellbare Abstreiferbleche angeordnet sein. Durch solche Abstreiferbleche kann vermieden werden, dass es zu unerwünschten Anhaftungen an den Walzen kommt.Underneath the gap formed between the two rollers, two adjustable scraper plates resting on the rollers can also be arranged within the housing. Such wiper plates can prevent undesirable buildup on the rollers.

Die beiden Walzen werden vorzugsweise durch jeweils einen Motor über jeweils ein Getriebe angetrieben. Auch die Einspeise- oder Dosiereinrichtung kann von einem Motor über ein Getriebe angetrieben werden.The two rollers are preferably each driven by a motor via a gear. The feed or metering device can also be driven by a motor via a gear.

Weitere Besonderheiten und Vorzüge der Erfindung ergeben sich aus der folgenden Beschreibung eines bevorzugten Ausführungsbeispiels anhand der Zeichnung. Es zeigen:

Figure 2
in the Figure 1 shown device for flaking or crushing food grain in a perspective.

Die in den Figuren 1 und 2 dargestellte Vorrichtung zum Flockieren oder Schroten von Speisegetreide enthält ein in Figur 1 in einem Schnitt dargestelltes Gehäuse 1, in dem zwei zueinander parallele und durch einen Spalt 2 voneinander getrennte Walzen 3 drehbar gelagert sind. Je nach Einsatzgebiet können die beiden Walzen 3 eine unterschiedliche Oberfläche aufweisen. Wird die Vorrichtung zum Flockieren eingesetzt, können die beiden Walzen z.B. eine gerändelte oder glatte Oberfläche aufweisen. Soll die Vorrichtung zum Schroten verwendet werden, können die beiden Walzen 3 eine geriffelte Oberfläche enthalten. Zumindest eine der beiden Walzen ist innerhalb des Gehäuses 1 über einen Stellmechanismus 4 so verstellbar angeordnet, dass der Spalt 2 zwischen den beiden Walzen 3 eingestellt und je nach Bedarf verändert werden kann. Über jeweils ein in Figur 2 dargestelltes und hier als Schneckenradgetriebe ausgeführtes Getriebe 5 und einen zugehörigen Antriebsmotor 6 können die beiden Walzen 3 zur Drehung in entgegengesetzter Richtung angetrieben werden.The in the Figures 1 and 2 shown device for flaking or crushing food grain contains a in Figure 1 Housing 1 shown in a section, in which two rollers 3 which are parallel to one another and separated by a gap 2 are rotatably mounted. Depending on the field of application, the two rollers 3 can have a different surface. If the device is used for flaking, the two rollers can have, for example, a knurled or smooth surface. If the device is to be used for grinding, the two rollers 3 can have a corrugated surface. At least one of the two rollers is arranged so that it can be adjusted within the housing 1 by means of an adjusting mechanism 4 such that the gap 2 between the two rollers 3 can be adjusted and changed as required. About one in each Figure 2 shown and here designed as a worm gear 5 and an associated drive motor 6, the two rollers 3 can be driven to rotate in the opposite direction.

Das Gehäuse 1 ist bei der gezeigten Ausführung auf einem mit vier höhenverstellbaren Füßen 7 versehenen Maschinengestell 8 montiert. Auf der Oberseite des Gehäuses 1 ist eine Einspeise- oder Dosiereinrichtung 9 mit einem Einfülltrichter 10 angeordnet. Über die Einspeise- oder Dosiereinrichtung 9 kann ein in dem Einfülltrichter 10 befindliches Getreide zum Spalt 2 zwischen den beiden Walzen 3 gefördert werden. Die Einspeise- oder Dosiereinrichtung 9 wird von einem Motor 11 über ein Getriebe 12 angetrieben und kann z.B. in Form einer Förderschnecke oder dgl. ausgebildet sein. Dadurch kann eine gesteuerte und genau dosierte Zufuhr von Getreide zu den beiden Walzen 3 erfolgen.In the embodiment shown, the housing 1 is mounted on a machine frame 8 provided with four height-adjustable feet 7. On the top of the housing 1, a feed or metering device 9 with a hopper 10 is arranged. A grain located in the hopper 10 can be conveyed to the gap 2 between the two rollers 3 via the feed or metering device 9. The feed or Dosing device 9 is driven by a motor 11 via a gear 12 and can be designed, for example, in the form of a screw conveyor or the like. This allows a controlled and precisely metered supply of grain to the two rollers 3.

An der Unterseite des Gehäuses 1 ist eine Sammel- und Abführeinrichtung 13 für das zwischen den beiden Walzen 3 verformte Speisegetreide angeordnet. Die Sammel- und Abführeinrichtung 13 weist einen unterhalb der beiden Walzen 3 angeordneten Auffangtrichter 14 und ein zu einem Sammelbehälter 15 führendes Austrittsrohr 16 auf. Das in den Sammelbehälter 15 ragende Austrittsrohr 16 ist in der Höhe verstellbar. Der Sammelbehälter 15 ist zwischen den Füßen 7 des Maschinengestells 8 angeordnet und kann durch einen Deckel verschlossen sein.On the underside of the housing 1, a collection and discharge device 13 is arranged for the feed grain deformed between the two rollers 3. The collection and discharge device 13 has a collecting funnel 14 arranged below the two rollers 3 and an outlet pipe 16 leading to a collection container 15. The height of the outlet tube 16 projecting into the collecting container 15 is adjustable. The collecting container 15 is arranged between the feet 7 of the machine frame 8 and can be closed by a lid.

An das Gehäuse 1 ist eine Absaugeinrichtung 17 zur Erzeugung einer über die Sammel- und Abführeinrichtung 13 von unten angesaugten und entlang der Außenseite der Walzen 3 nach oben führenden Absaugluft 18 angeschlossen. Die Absaugeinrichtung 17 umfasst einen Staubsauger 19 und eine Ansaugleitung 20 mit zwei oberhalb der beiden Walzen 3 in das Gehäuse 1 einmündenden Ansaugstutzen 21. Durch die Absaugeinrichtung 17 strömt die Absaugluft 18 von unten durch das Austrittsrohr 16 und den Auffangtrichter 14 an den zur Innenwand des Gehäuses 1 gewandten Außenseiten der beiden Walzen 3 entlang zur Oberseite des Gehäuses 1. In der Ansaugleitung 20 ist ein Drosselventil 22 zur Regulierung der Luftströmung vorgesehen. Der Staubsauger 19 weist in an sich bekannter Weise ein Gebläse zur Erzeugung eines Unterdrucks auf. In dem Staubsauger 19 können ferner geeignete Filter angeordnet sein.A suction device 17 is connected to the housing 1 for generating suction air 18 which is sucked in from below via the collecting and discharging device 13 and leads upwards along the outside of the rollers 3. The suction device 17 comprises a vacuum cleaner 19 and a suction line 20 with two suction nozzles 21 opening above the two rollers 3 1 facing outside of the two rollers 3 along to the top of the housing 1. In the intake line 20, a throttle valve 22 is provided for regulating the air flow. The vacuum cleaner 19 has a fan for generating a negative pressure in a manner known per se. Suitable filters can also be arranged in the vacuum cleaner 19.

Wie aus Figur 1 hervorgeht, kann über den im Staubsauger 19 erzeugten Unterdruck Luft über das Austrittsrohr 16 der Sammel- und Abführeinrichtung 13 angesaugt und an den zur Innenwand des Gehäuses 1 gewandten Außenseiten der beiden Walzen 3 entlang zu den Ansaugstutzen 21 geleitet werden. Durch die so erzeugte Luftströmung 18 können die während der Behandlung des Getreides zwischen den Walzen 3 entstehenden Staubpartikel 23 zur Oberseite des Gehäuses 1 geführt und über die Ansaugleitung 20 zu dem Staubsauger 19 geleitet werden. Innerhalb des Staubsaugers 19 können die Staubpartikel 23 dann über einen oder mehrere Filter abgeschieden werden. Die in dem Spalt 2 zwischen den beiden Walzen 3 verformten Getreidekörper 24 können dagegen über den Auffangtrichter 14 und das Austrittsrohr 16 der Sammel- und Abführeinrichtung 13 nach unten in den Sammelbehälter 15 fallen. Der Staubsauger 19 ist auf der einen Seite des Maschinengestells angeordnet. Auf der anderen Seite des Maschinengestells ist ein Schaltschrank 25 befestigt.How out Figure 1 emerges, air can be sucked in via the underpressure generated in the vacuum cleaner 19 via the outlet pipe 16 of the collecting and discharge device 13 and can be guided along the outer sides of the two rollers 3 facing the inner wall of the housing 1 to the suction nozzle 21. Due to the air flow 18 generated in this way, the dust particles 23 formed during the treatment of the grain between the rollers 3 can be guided to the top of the housing 1 and can be guided to the vacuum cleaner 19 via the suction line 20. The dust particles 23 can then be separated out within the vacuum cleaner 19 via one or more filters. The grain bodies 24 deformed in the gap 2 between the two rollers 3, on the other hand, can go down into the collecting container 15 via the collecting funnel 14 and the outlet pipe 16 of the collecting and discharging device 13 fall. The vacuum cleaner 19 is arranged on one side of the machine frame. A control cabinet 25 is attached to the other side of the machine frame.

Aus Figur 1 ist auch ersichtlich, dass innerhalb des Gehäuses 1 oberhalb des zwischen den beiden Walzen 3 gebildeten Spalts 2 zwei entgegengesetzt schräge Leitbleche 26 angeordnet sind. Durch diese Leitbleche 26 wird das über die Einspeise- oder Dosiereinrichtung 9 zugeführte Speisegetreide einerseits zu dem Spalt 2 gelenkt, andrerseits werden durch diese Leitbleche 26 die Ansaugstutzen 21 abgeschirmt und dadurch verhindert, dass das über die Einspeise- oder Dosiereinrichtung 9 zugeführte Speisegetreide noch vor der Bearbeitung über die Ansaugstutzen 21 angesaugt wird. Unterhalb des Spalts 2 sind innerhalb des Gehäuses 1 außerdem zwei an den Walzen 3 anliegende und einstellbare Abstreiferbleche 27 angeordnet. Dadurch kann vermieden werden, dass es zu unerwünschten Anhaftungen an den Walzen 3 kommt.Out Figure 1 it can also be seen that two oppositely sloping guide plates 26 are arranged inside the housing 1 above the gap 2 formed between the two rollers 3. By means of these guide plates 26, the feed grain fed via the feed or metering device 9 is guided on the one hand to the gap 2; Machining is sucked in through the intake manifold 21. Underneath the gap 2, two adjustable scraper plates 27, which bear against the rollers 3, are also arranged within the housing 1. This can prevent undesired buildup on the rollers 3.
