Abstract

A malt barley steeping reactor has a floor (4) over an air chamber (11). The floor (4) has especially a gas-permeable cover (10) made of a sintered material. The covering is gas-permeable in a single direction.

Description

Die Erfindung betrifft eine Flachbodenweiche für das Einweichen und Belüften von Ger­ ste in Mälzereien nach dem Oberbegriff des Patentanspruchs.The invention relates to a flat-bottom switch for soaking and aerating Ger malt plants according to the preamble of the claim.

Flachbodenweichen sind ein übliches Element im Mälzereibetrieb. In der Weiche wird z. B. Gerste eingeweicht und mit Sauerstoff belüftet. Entstehendes CO2 wird abgesaugt. Die Gerste verbleibt bis ca. 2 Tage in der Weiche und wird dann für die anschliessende Keimung umgeladen.Flat-bottom switches are a common element in malting. In the switch, for. B. Soaked barley and aerated with oxygen. The resulting CO 2 is extracted. The barley remains in the switch for up to 2 days and is then reloaded for subsequent germination.

Die Rahmen von Flachweichen weisen zumeist ein Lochblech oder dergleichen auf und unter diesem Boden ist ein Luftraum zur Belüftung und zum Abziehen des CO2 vorhan­ den.The frames of flat switches mostly have a perforated plate or the like and under this floor there is an air space for ventilation and for removing the CO 2 .

So beschreibt die DE-OS 29 04 840 einen Hordenboden mit einem Stützgestell aus Trä­ gern und einem darauf liegenden, perforierten Blech. Unterhalb des Hordenbodens sind Luftzuführöffnungen angeordnet, die mit einem Gebläse in Verbindung stehen. Der Hordenboden ist als Teil eines Kastens mit diesem schwenkbar angeordnet.DE-OS 29 04 840 describes a tray with a support frame made of Trä like and a perforated sheet on it. Are below the tray floor Air supply openings arranged, which are connected to a blower. The Tray floor is arranged as part of a box with this swivel.

Nach der EP-A-171553 wird zu weichenden und zu keimendes Gut in einer geschlos­ senen Vorrichtung einem Unterdruck ausgesetzt, der dem Wasserdampfdruck ent­ spricht.According to EP-A-171553, material to be softened and germinated is closed in one his device exposed to a negative pressure that ent the water vapor pressure speaks.

Der Luftraum ist auf Grund des Lochbodens wie der Prozessraum auch mit Wasser an­ gefüllt. Dieses Wasser wiederum verschmutzt infolge des Schmutzeintrages durch das Lochblech und ist als Abwasser zu behandeln. Die Reinigung des Luftraumes gestaltet . sich aufwändig, der Hordenboden muss aufklappbar und/oder anhebbar sein. Ein ma­ nuelles Reinigen ist erforderlich. Bei automatischen Flachweichen ist eine Abwasse­ rentleerung sowie eine Waschmöglichkeit gegeben. Dies vereinfacht zwar den Reinigungsvorgang, erfordert aber zusätzliche Investitionen und kann den Nachteil der Wäs­ serung des Luftraumes nicht beheben.Due to the perforated floor, the air space is also filled with water like the process room filled. This water, in turn, becomes contaminated due to the entry of dirt through the Perforated sheet and is to be treated as waste water. Airspace cleaning designed. complex, the tray bottom must be hinged and / or raised. A ma clean cleaning is required. With automatic flat switches there is waste water emptying and a washing facility. Although this simplifies the cleaning process,  but requires additional investment and can be the disadvantage of water Do not fix airspace changes.

Die Aufgabe der Erfindung besteht nun darin, die Verschmutzung des unter Flachbo­ denweichen befindlichen Luftraumes deutlich zu reduzieren und dabei auch den Was­ serverbrauch zu senken.The object of the invention is now the pollution of under flat bo to significantly reduce the soft airspace and also the what reduce water consumption.

Dieses Aufgabe ist mit den kennzeichnenden Merkmalen des Patentanspruchs gelöst.This object is achieved with the characterizing features of the patent claim.

Vorteilhafte Ausgestaltungen geben die Merkmale der Unteransprüche wieder.Advantageous refinements reflect the features of the subclaims.

Der Erfindung liegt der Gedanke zugrunde, die beidseitig durchlässigen Lochbleche der Weichenböden durch an sich bekannte und lediglich gasdurchlässige Beläge zu erset­ zen. Dies hat den Vorteil, dass das zu weichende Gut von unten belüftet werden kann, der Durchtritt von Wasser in den Luftraum jedoch vermieden wird. Demontage und Zu­ gang können vereinfacht werden.The invention is based on the idea of permeable perforated plates on both sides Switch floors to be replaced by known and only gas-permeable coverings Zen. This has the advantage that the material to be softened can be ventilated from below, however, the passage of water into the airspace is avoided. Disassembly and To can be simplified.

Als Bodenbelag können zum Beispiel Sinterplatten eingesetzt werden.Sintered plates, for example, can be used as the floor covering.

Die Erfindung wird nachfolgend in einem Ausführungsbeispiel an Hand einer Zeichnung näher beschrieben. Die Zeichnung zeigt in der einzigen Figur eine Weiche mit Flachbo­ den im Schnitt.The invention is described in an exemplary embodiment based on a drawing described in more detail. The drawing shows a switch with a flat board in the single figure the average.

Eine geschlossene Flachbodenweiche 1 weist übliche Einläufe 2 für die zu weichende Gerste, einen verschliessbaren Auslauf 3 für die Gerste, einen aufklappbaren Horden­ boden 4, eine Einrichtung zur Luftzufuhr sowie einen Abzug 5 für entstehendes CO2 auf. Die Luftzufuhr erfolgt durch eine Öffnung 6 unterhalb des Hordenbodens 4 (Luft­ raum 11), die mit einem Ventil steuerbar und verschliessbar ist. Die Luft wird durch ei­ nen nicht dargestellten Druckluftverdichter bereitgestellt.A closed flat-bottom switch 1 has conventional inlets 2 for the barley to be softened, a closable outlet 3 for the barley, a hinged tray 4 , a device for air supply and a vent 5 for CO 2 . The air is supplied through an opening 6 below the tray bottom 4 (air space 11 ), which can be controlled and closed with a valve. The air is provided by a compressed air compressor, not shown.

Der Hordenboden 4 weist einen Rahmen 9 aus Lochblech auf, auf den ein Belag 10 aus einem lediglich gasdurchlässigen Werkstoff aufgebracht oder aufgelegt ist. The tray bottom 4 has a frame 9 made of perforated sheet metal, on which a covering 10 made of a material which is only gas-permeable is applied or placed.

Nicht dargestellt sind übliche Einrichtungen zur Bereitstellung von Weichwasser sowie zur Abwasserentleerung etc. Nur schematisch dargestellt ist ein Räumaggregat 8.Conventional devices for providing soft water and for emptying wastewater etc. are not shown. A clearing unit 8 is only shown schematically.

Das Belüften mit Frischluft und die Absaugung von CO2 erfolgt durch den Raum unter­ halb der Horde. Die eingebrachte Luft durchdringt den Belag 10 und belüftet die einge­ weichte Gerste (Prozessraum, Weiche). Entstehendes CO2 wird durch den Belag 10 abgezogen und über den Abzug 5 einer nicht dargestellten Absaugung zugeführt.Ventilation with fresh air and extraction of CO 2 takes place through the room below half of the horde. The introduced air penetrates the covering 10 and aerates the soaked barley (process room, switch). Resulting CO 2 is drawn off through the covering 10 and fed to a suction device (not shown) via the discharge 5 .
