Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to a device according to the preamble of claim 1.

Eine vorrichtung dieser Art ist aus der GB-A-701169 bekannt. Mais wird heute in grossen Mengen zu den verschiedensten Endprodukten verarbeitet. Ausser der Nassentkeimung der Maiskörner für die Stärkeherstellung erfolgt deren Entkeimen und Mahlen für die übrigen Verwendungszwecke auf müllerischem Weg. Die Endprodukte der müllerischen Verarbeitung werden im wesentlichen der Futtermittel- und Ölindustrie, der Brauereiindustrie, der Polentagriessherstellung, der Snackprodukteindustrie oder der Cornflakesherstellung zugeführt. Jeder dieser Verwendungszwecke stellt unterschiedliche Anforderungen an die müllerische Verarbeitung, wobei in der Reihenfolge der genannten Verwendungszwecke der Investitions- und der Verarbeitungsaufwand für die müllerische Verarbeitung steigen.A device of this type is known from GB-A-701169. Today, corn is processed in large quantities to produce a wide variety of end products. In addition to the wet disinfection of the corn kernels for the starch production, their disinfection and grinding for the other uses is carried out in a mill-based way. The end products of mill processing are mainly supplied to the animal feed and oil industry, the brewery industry, the Polish Tagries production, the snack product industry or the corn flake production. Each of these uses places different demands on mill processing, with the investment and processing costs for mill processing increasing in the order of the uses mentioned.

Die erfindungsgemässe Vorrichtung dient der Herstellung von Flaking Grits, die das Ausgangsprodukt für die Cornflakesherstellung darstellen. Hier sind die Anforderungen an die Müllerei am höchsten. Seit Jahrzehnten erfolgt hierfür die Maisentkeimung und -schälung im "Beall-Entkeimer". Dieser weist einen Stator auf, in dessen Statorgehäuse ein Rotor drehbar gelagert ist. Das Statorgehäuse und der Rotor bilden einen wenigstens näherungsweise im Querschnitt ringförmigen Behandlungsraum und haben an ihren einander zugewandten Seiten Noppen. Die Statorinnenseite ist in Umfangsrichtung zudem abwechselnd in mit Noppen bzw. in mit einer Sieblochung versehene Durchfallsegmente unterteilt. Diese bekannte Vorrichtung hat weiter ein zweiteiliges Statorgehäuse, dessen beide Hälften durch eine horizontale Ebene getrennt und um eine Scharnierachse gegeneinander schwenkbar und im geschlossenen Zustand miteinander verschraubbar sind. Wird die obere Hälfte des Statorgehäuses entfernt (hochgeklappt), bildet die untere Hälfte eine im Querschnitt halbkreisförmige Mulde, in der der in endseitigen Lagerhalbschalen gehaltene Rotor liegt. Durch ein Hochklappen der oberen Statorgehäusehälfte wird die untere Hälfte des Behandlungsraumes daher nicht zugänglich. Der Rotor muss hierfür zusätzlich ausgebaut werden. Der Beall-Entkeimer hat weiter einen konischen Arbeitsraum, der sich vom Eintrittsende zum Abwurfende im Durchmesser vergrössert und entsprechend sind das Statorgehäuse und der Rotor konisch ausgebildet. Ist der Arbeitsraum in Richtung des Rotorradius entsprechend der Beschaffenheit des zu verarbeitenden Mais zu verändern, so wird der Rotor achsial im Statorgehäuse verschoben. Dies erfordert eine vergleichsweise aufwendige Lagerung. Müssen solche Maschinen für grössere Leistungen mit längeren Behandlungsräumen gebaut werden, wird zwangsweise auch der Durchmesser von Rotor und Statorgehäuse gegen das Abwurfende hin entsprechend vergrössert. Ein weiterer Nachteil dieser Vorrichtung ist die Tatsache, dass der Maisstaubanteil in den Flaking Grits hoch ist, was die Ausbeute verschlechtert.The device according to the invention is used to produce flaking grits, which are the starting product for cornflake production. This is where the demands on the milling shop are highest. For this, corn disinfection and peeling has been carried out in the "Beall sterilizer". This has a stator, in the stator housing of which a rotor is rotatably mounted. The stator housing and the rotor form an at least approximately annular treatment space in cross-section and have knobs on their mutually facing sides. The inside of the stator is also divided in the circumferential direction alternately into diarrhea segments provided with knobs or perforated perforations. This known device also has a two-part Stator housing, the two halves of which are separated by a horizontal plane and can be pivoted relative to one another about a hinge axis and can be screwed together in the closed state. If the upper half of the stator housing is removed (folded up), the lower half forms a trough which is semicircular in cross section and in which the rotor held in the end bearing half-shells lies. The lower half of the treatment room is therefore not accessible by folding up the upper stator housing half. The rotor must also be removed for this. The Beall sterilizer also has a conical working space that increases in diameter from the inlet end to the discharge end, and the stator housing and the rotor are accordingly conical. If the working area is to be changed in the direction of the rotor radius according to the nature of the maize to be processed, the rotor is displaced axially in the stator housing. This requires comparatively complex storage. If such machines have to be built for larger outputs with longer treatment rooms, the diameter of the rotor and stator housing is necessarily increased accordingly towards the discharge end. Another disadvantage of this device is the fact that the amount of corn dust in the flaking grits is high, which worsens the yield.

Die vorliegende Erfindung stellt sich die Aufgabe, eine Vorrichtung der erwähnten Art derart zu verbessern, dass der Behandlungsraum im Störungsfall leicht zugänglich und der Schäl- und Entkeimvorgang optimal führbar ist. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The object of the present invention is to improve a device of the type mentioned in such a way that the treatment room is easily accessible in the event of a fault and the peeling and sterilization process can be carried out optimally. This object is achieved by the characterizing features of claim 1.

Durch die an den lösbaren Gehäusewandteilen vorgesehenen, radial verstellbaren Noppensegmente können bei laufender Maschine Verstopfungen im Behandlungsraum behoben werden. Weiter kann der Querschnitt des Behandlungsraumes ohne achsiale Verschiebung des Rotors der Beschaffenheit des Verarbeitungsgutes angepasst werden.The radially adjustable nub segments provided on the detachable housing wall parts can be used to remove blockages in the treatment room while the machine is running. Furthermore, the cross section of the treatment room can be adapted to the condition of the material to be processed without axial displacement of the rotor.

Hat der im Querschnitt ringförmige Behandlungsraum über seine ganze Länge den gleichen oder mindestens näherungsweise gleichen Durchmesser, so kann dessen Länge vergrössert werden, ohne dass die Maschine in Breite und Höhe raumbeanspruchender wird. Zudem wird durch diese Massnahme der Staubanfall im Abwurf stark reduziert und die erforderliche Antriebsleistung wird bei gleichem Produktsdurchsatz kleiner. Der geringe Staubanteil im Abwurf hat den Vorteil, dass dieser nicht wie bisher gemeinsam mit dem Durchfall den weiteren Sichtern zugeführt werden muss. Der Aufwand für die nachfolgende Sichtung wird dadurch geringer. Ein weiterer Vorteil ergibt sich dadurch, dass bei gleicher Rotorlänge wie beim Beall-Entkeimer und bei gleicher Arbeitsqualität die Leistung bei halbem Kraftbedarf verdoppeln lässt.If the treatment area, which is ring-shaped in cross section, has the same or at least approximately the same diameter over its entire length, its length can be increased without the width and height of the machine taking up more space. In addition, this measure greatly reduces the amount of dust in the discharge and the required drive power is reduced with the same product throughput. The low dust content in the discharge has the advantage that it does not have to be fed to the other classifiers together with the diarrhea as before. The effort for the subsequent sighting is thereby reduced. Another advantage is that with the same rotor length as the Beall sterilizer and the same quality of work, the output can be doubled with half the power requirement.

Weist die erfindungsgemässe Vorrichtung die Merkmale der Ansprüche 6 und 7 auf, kann der Behandlungsraum im Störungsfalle mit wenigen Handgriffen über einen Umfangswinkel von zirka 270° freigelegt und die Störung behoben werden.If the device according to the invention has the features of claims 6 and 7, the treatment room in the event of a malfunction can be uncovered with a few hand movements over a circumferential angle of approximately 270 ° and the malfunction can be remedied.

Bei der Ausführungsform nach Anspruch 6 besteht die Möglichkeit, in den Endbereichen des Behandlungsraumes den radialen Abstand der verstellbaren Noppensegmente unterschiedlich einzustellen und damit die Arbeitsweise der Vorrichtung optimal einzustellen.In the embodiment according to claim 6, it is possible to set the radial distance of the adjustable nub segments differently in the end regions of the treatment room and thus to optimally adjust the operation of the device.

Ist der Rotor entsprechend dem Anspruch 13, gestaltet können die einem starken Verschleiss unterworfenen Noppensegmente sowohl statorseitig als auch rotorseitig ausgewechselt werden, ohne dass der Rotor ausgewechselt werden muss. Dadurch werden die Stillstandzeiten der Maschine und der Unterhaltsaufwand stark verringert.If the rotor is designed according to claim 13, the knob segments subjected to heavy wear can be replaced both on the stator side and on the rotor side without the rotor having to be replaced. This significantly reduces machine downtimes and maintenance costs.

Der Stator 1 der in den Fig. 1 und 2 gezeigten Vorrichtung weist ein Statorgehäuse 2 auf, das einen darin drehbar gelagerten Rotor 3 umgibt und auf den horizontalen Tragrahmen 5 eines Ständers 4 montiert und nach unten in einen anschliessenden Trichter 6 offen ist. Durch diesen wird der Durchfall abgeführt. Eine Längsstrebe 7, auf der ein Noppensegment 8 mit gegen den Behandlungsraum 9 gerichteten Noppen befestigt ist, überbrückt den Rahmen 5 in Längsrichtung. Das Statorgehäuse 2 ist endseits je durch eine Stirnplatte 10 und 11 geschlossen deren Oberseiten durch eine Längsstrebe 12 verbunden und versteift sind. Diese trägt ein weiteres Noppensegment 13, dessen in den Behandlungsraum 9 gerichtete Noppen jenen des Noppensegmentes 8 diametral gegenüber liegen. Zudem ist sie mit zwei einstellbaren Aspirationsschlitzen A) versehen, damit der Raum des Durchfalls hinreichend belüftbar ist. Die Schraubverbindung zwischen der Längsstrebe 12 und dem Noppensegment 13 kann durch Verstellschrauben erfolgen, mit denen der radiale Abstand des Noppensegments 13 vom Rotor 3 einstellbar ist.The stator 1 of the device shown in FIGS. 1 and 2 has a stator housing 2 which surrounds a rotor 3 which is rotatably mounted therein and is mounted on the horizontal support frame 5 of a stand 4 and is open at the bottom into a subsequent funnel 6. The diarrhea is drained through this. A longitudinal strut 7, on which a knob segment 8 is fastened with knobs directed against the treatment space 9, bridges the frame 5 in the longitudinal direction. The stator housing 2 is closed at the ends by an end plate 10 and 11, the upper sides of which are connected and stiffened by a longitudinal strut 12. This carries a further knob segment 13, the knobs directed into the treatment space 9 lying diametrically opposite those of the knob segment 8. She is also with Provide two adjustable aspiration slots A) so that the area of the diarrhea can be adequately ventilated. The screw connection between the longitudinal strut 12 and the knob segment 13 can be made by means of adjusting screws with which the radial distance of the knob segment 13 from the rotor 3 can be adjusted.

Zwischen den beiden Stirnplatten 10 und 11 und zu gegenüber liegenden Seiten der Längsstreben 7 und 12 sind weiter zwei lösbare Gehäusewandteile 14 und 15 des Statorgehäuses 2 vorhanden. An deren Enden befinden sich Winkelprofile 16, die mit den Stirnplatten 10 bzw. 11 verschraubt sind. An die beiden Stirnplatten 10 und 11 grenzen die Gehäusewandteile 14 und 15 mit Endplatten 17, die unter sich durch zwei Winkelprofilleisten 18 und 19 und eine U-Profilstrebe 20 fest verbunden sind. In die U-Profilstrebe 20 ist ein weiteres Noppensegment 21 eingeschraubt. Weiter ist zwischen der U-Profilstrebe 20 einerseits und den L-Profilleisten anderseits je ein Durchfallsegment 22 in Form eines Lochblechs befestigt. Die L-Profilleisten 18, 19, die U-Profilstrebe 20 mit dem Noppensegment 21 sowie die Endplatten 17 bilden eine bauliche Einheit. Diese bildet mit den Winkelprofilen 16 einen Gehäusewandteil 14 oder 15 mit denen sie an den Enden je durch eine Verstellschraube 23 verbunden sind. Bei einem Drehen der Verstellschrauben 23, wozu der manuelle Kraftaufwand gering ist, wird die ganze Baueinheit gegen die Längsmittelachse des Behandlungsraumes hin oder von dieser weg verschoben. Wird die Verschraubung zwischen den Winkelprofilleisten 16 und den anliegenden Stirnplatten 10, 11 gelöst, können beide Gehäusewandteile 14, 15, das heisst, die Baueinheit 17 bis 21 einschliesslich die Winkelprofilleisten 16 nach der Seite weggenommen und der Behandlungsraum 9 mit dem Rotor 3 weitgehend frei gelegt werden.Between the two end plates 10 and 11 and on opposite sides of the longitudinal struts 7 and 12 there are two detachable housing wall parts 14 and 15 of the stator housing 2. At the ends there are angle profiles 16 which are screwed to the end plates 10 and 11, respectively. At the two end plates 10 and 11, the housing wall parts 14 and 15 border with end plates 17, which are firmly connected to one another by two angle profile strips 18 and 19 and a U-profile strut 20. Another knob segment 21 is screwed into the U-profile strut 20. Furthermore, a diarrhea segment 22 in the form of a perforated plate is fastened between the U-profile strut 20 on the one hand and the L-profile strips on the other. The L-profile strips 18, 19, the U-profile strut 20 with the knob segment 21 and the end plates 17 form a structural unit. This forms with the angle profiles 16 a housing wall part 14 or 15 with which they are each connected at the ends by an adjusting screw 23. When the adjusting screws 23 are turned, for which the manual effort is low, the entire structural unit is displaced towards or away from the longitudinal center axis of the treatment room. If the screw connection between the angle profile strips 16 and the adjacent end plates 10, 11 is released, both housing wall parts 14, 15, that is to say the structural unit 17 to 21 including the angle profile strips 16, can be removed to the side and the treatment room 9 with the rotor 3 can be largely exposed will.

Ein im Querschnitt achteckiges Hohlprofil mit endseitigen Achsstummeln 25 bildet den Kern 24 des Rotors 3. Mit diesen ist er in Drehlagern des Statorgehäuses 2 antreibbar gelagert. Über die Länge des Kerns 24 sind auf dessen ebenen Abschnitten im Querschnitt kreissegmentartige Noppenplatten 26 lösbar aufgeschraubt. Diese Noppenplatten 26 sind stachelartig mit Noppen besetzt, wobei die Noppen im Eintrittsbereich (Fig. 1, links) wendelförmig angeordnet oder strukturiert sind.A hollow cross-section with an octagonal cross section and end stub axles 25 forms the core 24 of the rotor 3. With these, it is mounted so that it can be driven in the pivot bearings of the stator housing 2. Over the length of the core 24, circular segment-like knob plates 26 are releasably screwed onto its flat sections in cross section. These knob plates 26 are studded with knobs, the knobs in the entry area (FIG. 1, left) being arranged helically or structured.

Die Umhüllungsfläche des Rotors 3 ist ein Zylindermantel. Entsprechend weist der Behandlungsraum 9 angenähert eine im Querschnitt ringzylindrische Form auf. Die relative Geschwindigkeit zwischen stator- und rotorseitigen Noppen ist daher über die ganze Länge des Behandlungsraumes gleich. Die Umhüllungsfläche kann indessen auch leicht konisch sein, ohne dass dadurch die Vorteile der Erfindung insgesamt in Frage gestellt wären. Wie die Fig. 3 zeigt, kann durch ein Drehen der Verstellschrauben 23 in radialer Richtung die Breite des Behandlungsraums 9 verändert werden, indem die sich gegenüber liegenden Noppenplatten 21 der beiden Gehäusewandteile 14, 15 mit den angrenzenden Durchfallsegmenten 22 gegen den Rotor 3 bzw. von diesem weg bewegt werden. Zweckentsprechend kann durch eine Einstellung der Verstellschrauben 23 die Breite des Behandlungsraumes 9 im Eintrittsbereich grösser oder kleiner als im Abwurfbereich eingestellt werden. Die Form des Behandlungsraumes 9 ist daher in optimaler Weise der Qualität der zu verarbeitenden Maissorte anpassbar.The enveloping surface of the rotor 3 is a cylinder jacket. Accordingly, the treatment room 9 approximately has a ring-cylindrical shape in cross section. The relative speed between the stator and rotor-side knobs is therefore the same over the entire length of the treatment room. The enveloping surface can, however, also be slightly conical, without thereby jeopardizing the advantages of the invention as a whole. As shown in FIG. 3, by turning the adjusting screws 23 in the radial direction, the width of the treatment room 9 can be changed by the opposing knob plates 21 of the two housing wall parts 14, 15 with the adjacent diarrhea segments 22 against the rotor 3 or from be moved away from this. Appropriately, by adjusting the adjusting screws 23, the width of the treatment room 9 in the entry area can be made larger or smaller than in the discharge area. The shape of the treatment room 9 can therefore be optimally adapted to the quality of the maize to be processed.

Der zu behandelnde Mais wird durch einen Einlaufstutzen 27 im Statorgehäuse 2 in den Behandlungsraum 9 geschüttet. Durch die wendelförmig strukturierte Oberfläche des Rotors im Eintrittsbereich werden die Maiskörner in den Behandlungsraum eingezogen, zwischen den Noppen zerrieben und gegen das entferntere Ende gedrückt, wo die den Abstoss bildenden Endospermteile in eine Kammer 28 zwischen dem Rotor 3 und der Stirnplatte 11 gelangen. Die Stirnplatte 11 ist von einer Austrittöffnung 29 durchsetzt, durch die der Abstoss in einen Austragtrichter 30 fällt und die mit einer Klappe 31 verschliessbar ist. Deren Schliesskraft ist durch ein Verstellgewicht 32 einstellbar, das auf einem mit der Klappe 31 fest verbundenen Waagarm 33 verschoben werden kann. Mit der Lage des Verstellgewichts 32 wird die Durchlaufzeit der Endospermteile durch den Behandlungsraum 9 beeinflusst.The maize to be treated is poured into the treatment room 9 through an inlet nozzle 27 in the stator housing 2. Due to the helically structured surface of the rotor in the inlet area, the maize kernels are drawn into the treatment room, ground between the knobs and pressed against the far end, where the endosperm parts forming the repulsion get into a chamber 28 between the rotor 3 and the end plate 11. The end plate 11 is penetrated by an outlet opening 29, through which the kick falls into a discharge funnel 30 and which can be closed with a flap 31. Its closing force can be adjusted by means of an adjustment weight 32 which can be moved on a weighing arm 33 which is firmly connected to the flap 31. The throughput time of the endosperm parts through the treatment room 9 is influenced by the position of the adjustment weight 32.

Während des Zerreibens des Maiskorns im Behandlungsraum 9 werden Schale, Keim und Endospermteile getrennt und die gelösten Schalen, die Keime und ein geringer Anteil der Endospermteile fallen durch die Durchfallsegmente 22 in den Trichter 6. Die grösseren Endospermteile durchwandern die Behandlungszone 9 und treten als Abstoss durch die Austrittsöffnung 29 in den Austragtrichter 30.During the grinding of the maize kernel in the treatment room 9, the husk, germ and endosperm parts are separated and the loosened husks, the germs and a small proportion of the endosperm parts fall through the diarrhea segments 22 into the funnel 6. The larger endosperm parts pass through the treatment zone 9 and pass through as a kick the outlet opening 29 into the discharge funnel 30.

Tritt im Betriebszustand der Maschine im Behandlungsraum 9 eine Verstopfung auf, so kann diese dadurch beseitigt werden, dass auf einer Seite das Noppensegment 21 mit den angrenzenden Durchfallsegmenten 22 durch ein Drehen der Verstellschrauben 23 radial nach aussen bewegt wird, bis sich die Verstopfung löst. Anschliessend wird das Noppensegment wieder in seine Arbeitslage gebracht.If a blockage occurs in the operating state of the machine in the treatment room 9, this can be eliminated by moving the knob segment 21 with the adjacent diarrhea segments 22 radially outwards by turning the adjusting screws 23 until the blockage is released. The knob segment is then brought back into its working position.

Durch den im Behandlungsraum stattfindenden Reibprozess sind sowohl die Noppenplatten 26 als auch die Noppensegmente 8, 13 und 21 einem starken Verschleiss unterworfen. Sind am Rotor 3 die Noppenplatten 26 zu ersetzen, so genügt es, eines der beiden Gehäusewandteile 14 oder 15 nach dem Lösen der Schraubenverbindungen 34 vollständig zu entfernen. Danach kann eine der Noppenplatten 26 nach der andern am Rotor 3 gelöst und ersetzt werden. Sind die vier Noppensegmente 8, 13 und 21 zu ersetzen, werden beide Wandteile 14 und 15 in der beschriebenen Art nach dem Lösen der Schraubenverbindungen 34 entfernt und die verschlissenen Noppensegmente ausgewechselt.As a result of the rubbing process taking place in the treatment room, both the knob plates 26 and the knob segments 8, 13 and 21 are subject to severe wear. If the knob plates 26 on the rotor 3 are to be replaced, it is sufficient to completely remove one of the two housing wall parts 14 or 15 after loosening the screw connections 34. Then one of the knob plates 26 can be loosened and replaced on the rotor 3. If the four knob segments 8, 13 and 21 are to be replaced, both wall parts 14 and 15 are removed in the manner described after loosening the screw connections 34 and the worn knob segments are replaced.

Eine Verdoppelung der Leistung bei geringstem konstruktiven Aufwand und Platzbedarf ergibt sich bei der Ausführungsform nach Fig. 5. Hier sind sowohl der Stator als auch der Rotor symmetrisch mit Bezug auf eine vertikale, zur Rotorachse rechtwinklige Symmetrieebene ausgebildet, in der der Einlaufstutzen 27 liegt. Der Produkteinzug erfolgt durch eine sich aus der Symmetrie ergebende entgegengerichtete Wendelstruktur am Rotor 3 im Eintrittsbereich und ebenso erfolgt der Abwurf der grösseren Endospermteile an beiden Enden des Rotorgehäuses in entsprechende Austragtrichter 30 bzw. 30′.The output according to FIG. 5 doubles the power with the least design effort and space. Here, both the stator and the rotor are formed symmetrically with respect to a vertical plane of symmetry perpendicular to the rotor axis, in which the inlet connector 27 lies. The product is drawn in through an opposite helical structure resulting from the symmetry on the rotor 3 in the entry area and likewise the larger endosperm parts are ejected at both ends of the rotor housing into corresponding discharge funnels 30 and 30 '.

Das durch den Einlaufstutzen 27 zugeführte Korngut wird im Behandlungsraum aufgeteilt und in zwei entgegengesetzte Richtungen umgelenkt. Nach beiden Richtungen wird das Korn der gleichen Behandlung unterworfen und der Durchfall entsprechend in zwei getrennten Trichtern 6, 6′ aufgefangen und für die weitere Verarbeitung wieder zusammengeführt. Auch der aus den Trichtern 30 und 30′ ausgetragene Abstoss, das heisst, die grösseren Endospermteile werden für die weitere Verarbeitung vereinigt.The grain material fed through the inlet nozzle 27 is divided in the treatment room and deflected in two opposite directions. In both directions, the grain is subjected to the same treatment and the diarrhea is caught in two separate funnels 6, 6 'and brought together again for further processing. Also the repulsion discharged from the funnels 30 and 30 ', that is, the larger endosperm parts are combined for further processing.

Fig. 6 zeigt eine Herstellungsanlage für Flaking Grits, in die eine erfindungsgemässe Vorrichtung 35 zum Schälen und Entkeimen der Maiskörner integriert ist. Nach den speziellen Aggregaten 36 für die Vorbereitung der Maiskörner mittels Wasser und/oder Dampf gelangen die Körner in die erfindungsgemässe Vorrichtung 35. Dank des mehl- und schalenfreien Abstosses, kann dieser direkt über einen Zyklon 37 einem Plansichter 38 zugeführt werden. Eine Vereinigung des Abstosses mit dem Durchfall, wie dies bei der Verwendung bekannter Vorrichtungen (wegen des Mehl- und Schalenanteils von bis zu 7% im Abstoss) erforderlich ist, ist nicht notwendig. Der Durchfall gelangt über weitere Zyklone 39 und 40 zu einem Turbosichter 41, der die im Durchfall enthaltenen Endospermteile ausscheidet und über eine Wägevorrichtung 42 einem zweiten Plansichter 43 zuführt. Der konstruktiv aufwendigere Reinigungsweg für den Durchfall mit einem Turbosichter kann, da er durch den Abstoss nicht mehr wie bisher belastet ist, kleiner und daher preisgünstiger dimensioniert werden.6 shows a manufacturing plant for flaking grits, in which a device 35 according to the invention for peeling and sterilizing the corn kernels is integrated. After the special aggregates 36 for the preparation of the corn kernels by means of water and / or steam, the kernels reach the device 35 according to the invention. Thanks to the flour- and shell-free repulsion, this can be fed directly to a plan sifter 38 via a cyclone 37. It is not necessary to combine the push-off with the diarrhea, as is necessary when using known devices (because of the flour and shell content of up to 7% in the push-off). The diarrhea passes through further cyclones 39 and 40 to a turbosifter 41 which separates the endosperm parts contained in the diarrhea and feeds them to a second plan sifter 43 via a weighing device 42. The structurally more complex cleaning route for diarrhea with a turbosifter can be made smaller and therefore less expensive since it is no longer burdened by the push-off as before.

Bei den Ausführungsbeispielen gemäss den Fig. 7 bis 11 bezeichnen gleiche Hinweisziffern gleiche Teile wie bei den Beispielen nach den Fig. 1 bis 5. Das Beispiel nach Fig. 7 unterscheidet sich von jenen dadurch, dass der radiale Abstand zwischen den Durchfallsegmenten 22 einerseits und dem Rotor 3 anderseits ebenfalls verstellbar ist. Zu diesem Zweck sind die Durchfallsegmente 22 endseits durch Flanschplatten 36, welche von einem Schlitzloch 37 durchbrochen sind, versteift. Diese Flanschplatten 36 liegen gegen die Endplatten 17 an. Weiter ist der an die Profilleiste 18 angrenzende Bereich des Durchfallsegmentes 22 nach aussen zurückgebogen, so dass er gegen diese eine Anlagefläche 38 bildet. Die Flanschplatte 36 ist an der Endplatte mittels einer durch das Schlitzloch 37 geführten Schraube 39 fest schraubbar und übergreift zudem den anderen, nach aussen abgewinkelten Endbereich des Durchfallsegmentes 22 mit einer Abkröpfung 40. Diese, wie auch das Durchfallsegment 22 sind mit einem Schlitzloch 41 versehen, durch die ein fest im Schenkel der U-Profilstrebe 20 sitzender Gewindeschaft 42 greift. Durch das Festziehen einer Mutter 43 auf dem Gewindeschaft 42 wird die Flanschplatte 36 mit der U-Profilstrebe 20 fest verbunden. Für die Verstellung des radialen Abstandes des Durchfallsegmentes 22 vom Rotor 3 brauchen somit lediglich die Schrauben 39 und die Muttern 40 gelockert und das Durchfallsegment verschoben zu werden.In the exemplary embodiments according to FIGS. 7 to 11, the same reference numerals designate the same parts as in the examples according to FIGS. 1 to 5. The example according to FIG. 7 differs from those in that the radial distance between the diarrhea segments 22 on the one hand and the Rotor 3 is also adjustable on the other hand. For this purpose, the diarrhea segments 22 are stiffened at the ends by flange plates 36, which are pierced by a slot 37. These flange plates 36 bear against the end plates 17. Furthermore, the area of the diarrhea segment 22 adjoining the profile strip 18 is bent outwards, so that it forms a contact surface 38 against the latter. The flange plate 36 is attached to the end plate a screw 39 guided through the slot 37 can be screwed tightly and also overlaps the other, outwardly angled end region of the diarrhea segment 22 with an offset 40 - Profile strut 20 seated threaded shaft 42 engages. By tightening a nut 43 on the threaded shaft 42, the flange plate 36 is firmly connected to the U-profile strut 20. For the adjustment of the radial distance of the diarrhea segment 22 from the rotor 3, therefore, only the screws 39 and the nuts 40 need to be loosened and the diarrhea segment to be displaced.

Beim Beispiel nach Fig. 8 ist das Statorgehäuse 2 gleich ausgebildet wie beim Beispiel nach Fig. 7. Verschieden ist die Gestaltung des Kernes 3. Nicht auf jedem ebenen Abschnitt des im Querschnitt achteckigen Kernes 24 sondern nur auf jedem zweiten ist eine Noppenplatte 26 angebracht. Die dazwischen liegenden Abschnitte sind mit einer ebenen Blindplatte 24 besetzt. Das Ausführungsbeispiel nach Fig. 9 unterscheidet sich von jenem nach Fig. 7 dadurch, dass die Durchfallsegmente 22 nicht parallel zum Umhüllungsmantel des Rotors 3 gebogen sondern eben sind.In the example according to FIG. 8, the stator housing 2 is of the same design as in the example according to FIG. 7. The design of the core 3 is different. A knob plate 26 is not attached to each flat section of the core 24 with an octagonal cross section, but only on every second. The intermediate sections are covered with a flat blind plate 24. The exemplary embodiment according to FIG. 9 differs from that according to FIG. 7 in that the diarrhea segments 22 are not curved parallel to the jacket of the rotor 3, but are flat.

Beim Beispiel nach Fig. 10 fehlen (im Unterschied zu den vorangehenden Beispielen) statorseitig die Noppensegmente. Die Noppensegmente 8 und 13 sind durch Blindplatten 45 und die Noppensegmente 21 durch Durchfallsegmente 46 ersetzt. Zudem weist der Behandlungsraum 9 einen achteckigen Ringquerschnitt auf.In the example according to FIG. 10, the knob segments are missing (in contrast to the preceding examples) on the stator side. The nub segments 8 and 13 are replaced by blind plates 45 and the nub segments 21 by diarrhea segments 46. In addition, the treatment room 9 has an octagonal ring cross section.

Beim Ausführungsbeispiel nach Fig. 11 sind die Noppensegmente 8 und 13 des Statorgehäuses vorhanden, wogegen die Noppensegmente 21 durch Durchfallsegmente ersetzt sind.In the exemplary embodiment according to FIG. 11, the nub segments 8 and 13 of the stator housing are present, whereas the nub segments 21 are replaced by diarrhea segments.
