Description

SCHALENSEPARATOR MIT MINDESTENS ZWEI PARALLEL ÜBEREINANDER LIEGENDEN AUSLESE ZONEN BOWL SEPARATOR WITH AT LEAST TWO PARALLEL READING ZONES
Die Erfindung betrifft einen Schalenseparator, insbesondere zur Separation der Schalen von Getreidekörnem, bevorzugt von geschältem Sraunreis.The invention relates to a husk separator, in particular for separating the husks from cereal grains, preferably from peeled Sraunreis.
Getreide, insbesondere Reis wird vor der weiteren Verarbeitung geschält. Bekannt sind hierzu Schälmaschinen mit Gummiwalzeπ. Diesen sind Schalenseparatoren nachgeordnet, um den geschälten Braunreis im Luftstrom sauber von den entfernten Schalenteilen trennen zu können. Bekannte Separatoren weisen drei Separationszonen auf und neben dem Braunreis werden mehrere Mischfraktionen u. a. gebildet.Grain, especially rice, is peeled before further processing. Peeling machines with rubber rollers are known for this purpose. These are followed by shell separators in order to be able to cleanly separate the peeled brown rice from the removed shell parts in the air flow. Known separators have three separation zones and in addition to the brown rice, several mixed fractions are u. a. educated.
Bei sogenannten Scalperatoren gelangt Weizen auf eine Vorreiπigungstrammel, die mit einem groben Drahtgewebe bespannt ist. Der Weizen passiert die Trommel und grobe Beimengungen werden aussortiert und abgestossen. Der Weizen wird nachfolgend aspiriert, um leichte Beimengungen zu entfernen, wobei der Aspirationsstrom mittels Ventilator in eine Niederschlagskammer gezogen wird. Eine Rückleltung der Luft zum Wiedergebrauch ist bereits gegeben. Sand oder Staub können nicht aus dem Produktstrom entfernt werden.In so-called scalperators, wheat comes to a pre-cleaning drum, which is covered with a coarse wire mesh. The wheat passes the drum and coarse additives are sorted out and rejected. The wheat is then aspirated to remove slight additions, the aspiration stream being drawn into a precipitation chamber by means of a fan. The air has already been returned for reuse. Sand or dust cannot be removed from the product stream.
Eine ähnliche Reinigungsmaschiπe für Weizen ist im RU-PS 2133149 beschrieben. Hierbei wird der Weizen zunächst vom Rund- und Langkornbesatz getrennt und anschliessend werden Leichtprodukte und Staub abgetrennt. Der Weizenstrom gelangt anschliessend in einen zusätzlichen pneumatischen Separationskanal, wo Schmachtkörner und Bruchkörner abgeführt werden. Die Luft wird gereinigt und erneut verwendet.A similar cleaning machine for wheat is described in RU-PS 2133149. The wheat is first separated from the round and long-grain trimmings and then light products and dust are separated. The flow of wheat then arrives in an additional pneumatic separation channel, from where gravel and broken grains are removed. The air is cleaned and reused.
Der Erfindung liegt nun die Aufgabe zugrunde, einen Schalenseparator zu schaffen, der eine effiziente Trennung der Schalen von Getreide, insbesondere von geschältem Braunreis ermöglicht. Dies bei wesentlich höherer Ausleseleistuπg und zumindest gleichbleibender Auslesequalität. Die Lösung die Aufgabe erfolgt mit den Merkmalen des Patentanspruchs. Erfindungsge- mäss werden mindestens zwei Einspeisungen parallel zur Produktverteilung für das Braunreis-Schalengemisch übereinander angeordnet und ein Umluftstrom auf zwei Auslesezonen gerichtet. Vorteilhaft kann die Luftverteilung durch eine Klappe eingestellt wer¬ den. Der Erfindung liegt die Erkenntnis zugrunde, dass nicht nur die Produktzuführung über die Breite der Auslesezone gleichmässig sein muss. Vielmehr darf bei Schalengemischen eine bestimmte Menge über die Breite der Einspeiselänge für eine genaue Auslese nicht überschritten werden, wobei bis zu einer Grenzleistung der Auslesefehler nur langsam, bei weiterem Leistungsanstieg aber sehr drastisch ansteigt.The invention is based on the object of creating a shell separator which enables efficient separation of the husks from cereals, in particular from husked brown rice. This with much higher readout performance and at least constant readout quality. The solution of the task is carried out with the features of the claim. According to the invention, at least two infeeds are arranged one above the other parallel to the product distribution for the brown rice husk mixture and a circulating air stream is directed onto two readout zones. Advantageously, the air distribution can be adjusted by a flap ¬ to. The invention is based on the knowledge that it is not only the product feed that has to be uniform over the width of the readout zone. Rather, in the case of shell mixtures, a certain amount over the width of the feed length must not be exceeded for an accurate readout, the readout error increasing only slowly up to a limit power, but increasing very drastically with a further increase in output.
Nach dem Sichten werden die Braunreisströme wieder zu einem Produktstrom vereinigt. Es entstehen nur zwei Separationsprodukte (Braunreis, Schalen), eine Mischfraktion wie beim Stand der Technik ist nicht erforderlich. Die Ausleseleistung kann bei gleicher Grund¬ fläche und nur unwesentlicher Vergrösserung der Bauhöhe und zumindest gleichbleibender Qualität wenigstens verdoppelt werden.After sifting, the brown rice streams are combined again to form a product stream. There are only two separation products (brown rice, shells), a mixed fraction as in the prior art is not necessary. The readout power can be at least doubled for the same reason ¬ area and only an insignificant increase of the height and at least the same quality.
Mittels eines steileren Verlaufs des Sichtkanals können zudem Schmachtkörner besser aus den Schalen entfernt werden. Die Einspeiselänge wird bei fast gleicher Maschinenbreite verdoppelt.A steeper course of the viewing channel also makes it easier for gravel to be removed from the shells. The feed length is doubled with almost the same machine width.
Die Erfindung wird nachfolgend in einem Ausführungsbeispiel an Hand einer Zeichnung näher beschrieben. Die Zeichnung zeigt in zwei teilweise geschnittene Ansichten (Figuren 1 und 2) einen Doppel-Schalenseparator und dessen Zuordnung zu einer Schälmaschine.The invention is described in more detail in an exemplary embodiment with reference to a drawing. The drawing shows in two partially sectioned views (Figures 1 and 2) a double-shell separator and its assignment to a peeling machine.
Die Schälmaschine, bevorzugt ein Gummiwalzenschäler 1 , wie er zum Beispiel in dem USP 4194445 oder der DE-A-10043998 offenbart ist, besteht aus einem Gehäuse mit einem Einlass 13 für ungeschälten Reis, einer Vibrospeisung 11 sowie einem Schälwalzenpaar 1a, 1 b, dessen erste Schälwalze ortsfest im Gehäuse gelagert ist und dessen zweite Schälwalze durch Anordnung an einem schwenkbeweglich am Gehäuse gelagerten Trä¬ ger relativ zur ersten Schälwalze beweglich ist und von einer vorgegebenen, äusseren Kraft gegen diese gepresst wird {nicht dargestellt). Von einem motorischen Antrieb 12 gelangt die Antriebskraft mittels eines endlosen Riemens 12a, der über je eine auf den Wellen der Schälwalzen 1a, 1b gelagerte, getriebene Antriebsscheibe 12b, 12c und wenigs- tens eine treibende Antriebsscheibe 12d sowie mindestens eine Spann- oder Umlenkscheibe 1 e geführt ist, an die Schälwalzen.The peeling machine, preferably a rubber roller peeler 1, as disclosed for example in USP 4194445 or DE-A-10043998, consists of a housing with an inlet 13 for unhulled rice, a vibro feed 11 and a pair of peeling rollers 1a, 1b, thereof first peeling roller fixedly mounted in the housing and whose second peeling roller is movable by arrangement on a pivotably mounted on the housing Trä ¬ ger relative to the first peel roller and is pressed by a predetermined external force against the {not shown). The driving force comes from a motorized drive 12 by means of an endless belt 12a, which is driven by a driven drive pulley 12b, 12c, which is mounted on the shafts of the peeling rollers 1a, 1b, and at least at least one driving drive pulley 12d and at least one tensioning or deflecting pulley 1 e are guided to the peeling rollers.
Von der Vibrospeisung 11 gelangt der ungeschälte Reis R auf eine schräge Rutsche 1c und von dieser direkt in den Walzenspalt.From the vibro feed 11 the unshelled rice R reaches an inclined slide 1c and from there directly into the roller gap.
Nach dem Passieren des Walzenspaltes zwischen den Schälwalzen 1a, 1 b gelangt das Gemisch aus geschältem Braunreis B und entfernten Schalen S in den, unterhalb des Gummiwalzenschälers 1 befindlichen Doppel-Schalenseparator 2. In einem Speisebereich wird das Gutgemisch mittels zweier Verteilschnecken 22, 22* gleichmässig über die gesamte Breite eines Sichtkanals 24 verteilt und vom Luftstrom 31 durchströmtAfter passing through the nip between the peeling rollers 1a, 1b, the mixture of husked brown rice B and removed shells S enters the double-shell separator 2 located below the rubber roller peeler 1. In a dining area, the good mixture is uniform by means of two distribution screws 22, 22 * Distributed over the entire width of a viewing channel 24 and flowed through by the air flow 31
Das Gemisch gelangt zu je etwa 50% auf die obere Verteilschnecke 22 bzw. die untere Verteilschnecke 22'.About 50% of the mixture each reaches the upper distribution screw 22 or the lower distribution screw 22 '.
Der Luftstrom ist so eingestellt, dass der Brauπ eis B nach unten gegen Sraunreϊsschne- cken 25, 25' fällt und seitlich ausgetragen wird (Auslass 35, 35'). Anschliessend werden beide Teilströme wieder zu einem Braunreisstrom zusammengeführt (nicht dargestellt). Der Sichtkaπal 24 weist einen steilen Verlauf ines Leitblechs 23 (alpha=45β) auf und im zunehmend verengten Sichtkanal 24 wird das verbleibende Gutgemisch bzw. die Schalen S beschleunigt und entlang einer gekrümmten Wand 26 einer Kammer 29 geführt. Die Schalen werden über die Schalenschnecke 27 ausgebracht. Die Luft wird im Kreislauf geführt. Der rückgeführte Luftstrom 31 (Umluft) wird mittels einer Verteilklappe 32 durch Siebbleche 33 geblasen und auf beide Auslesezonen 34, 34' geleitetThe air flow is adjusted so that the brewing ice B falls down against the screw 25, 25 'and is discharged to the side (outlet 35, 35'). The two partial flows are then combined again to form a brown rice flow (not shown). The sight channel 24 has a steep course in the guide plate 23 (alpha = 45 β ) and in the increasingly narrow sight channel 24 the remaining mixture of good or the shells S is accelerated and guided along a curved wall 26 of a chamber 29. The shells are brought out via the shell screw 27. The air is circulated. The recirculated air flow 31 (circulating air) is blown through sieve plates 33 by means of a distribution flap 32 and directed to both readout zones 34, 34 '
Eine oben unterhalb des unteren Leitblechs 23 angeordnete Bypassklappe 28 verhindert eine Beeinträchtigung des Ansaugverhaltens des Ventilators 30 durch den Luftstrom. Weitere Leitbleche sind so angeordnet, dass Schmachtkornteile besser aus den Schalen über dem Boden des Sichtkanals 24 separiert werden können (nicht dargestellt).A bypass flap 28 arranged at the top below the lower guide plate 23 prevents the suction behavior of the fan 30 from being impaired by the air flow. Further baffles are arranged in such a way that parts of the slag are easier to separate from the shells above the bottom of the viewing channel 24 (not shown).
Der Ventilator 30 weist einen Einzelantrieb auf und für die Schnecken 22, 22\ 25, 25\ 27 sind ein oder mehrere Antriebe vorgesehen welche eine Drehzahtanpassung und bessere Verteilung der Antriebsleistung ermöglichen. Der Gummiwalzenschäler 1 ist seitlich versetzt oberhalb der Schnecken aufgestellt und der Auslaufbereich des Gurnmiwalzenschälers 1 (oberhalb des Speisebereichs 21 des Schalenseparators 2) ist mit einem Trennblech 36 in zwei ca. gleich grosse Kanäle 37, 38 aufgeteilt.The fan 30 has a single drive and one or more drives are provided for the screws 22, 22 \ 25, 25 \ 27, which enable speed adjustment and better distribution of the drive power. The rubber roller peeler 1 is set laterally offset above the screws and the outlet area of the rubber roller peeler 1 (above the dining area 21 of the shell separator 2) is divided into two approximately equal-sized channels 37, 38 with a separating plate 36.
Die Breite und die Höhe des Schalenseparators 2 sind nur um wenige Zentimeter im Vergleich zu einem konventionellen Schalenseparatαr vergrössert, bedingt durch die zweite Einspeisung, resp. die zweite Auslesezone. The width and the height of the shell separator 2 are only increased by a few centimeters in comparison to a conventional shell separator, due to the second feed, respectively. the second readout zone.
