Description

60 des Leitbleches sind so aufeinander abgestimmt, daß der untere schwenkbare Teil 60 des Leitbleches 48 mit seiner unteren Kante 68 knapp am Umfang der Walze 14 vorbei geschwenkt werden kann. 60 of the guide plate are coordinated so that the lower pivotable part 60 of the guide plate 48 can be pivoted with its lower edge 68 just past the circumference of the roller 14.

Die Betriebsweise der soweit beschriebenen Anlage ist wie folgt:The operation of the system described so far is as follows:

Das in dem Silo 20 aufbewahrte Malz wird durch eine von dem Wasserzulauf 42 abzweigende Leitung 70 befeuchtet. Wenn genügend Befeuchtungswasser zugeführt ist, wird dieses durch die Pumpe 24, die Maischeleitung 28, das Dreiwegeventil 30 und die Leitung 32 wiederholt umgepumpt. Nach ausreichender Befeuchtung des Malzes werden die Speisewalze 18 und die Quetschwalzen 14, 16 in Drehung versetzt. Das durch die Quetschwalzen 14 gequetschte Malz wird mit dem durch den Wassenzulauf 42 ankommenden Wasser vermittels des Cpritztellers 40 vermischt und als Maische durch die Maischepumpe 24 und die Maischeleitung 28 zu einem nicht eingezeichneten Maischegefäß im Sudhaus wc itergeleitet?The malt stored in the silo 20 is fed through a line branching off from the water inlet 42 70 moistened. If enough humidifying water is supplied, this is by the pump 24, the Mash line 28, three-way valve 30 and line 32 are repeatedly pumped around. After sufficient The feed roller 18 and the nip rollers 14, 16 are set in rotation when the malt is moistened. The malt squeezed by the nip rollers 14 is mixed with the malt arriving through the water inlet 42 Water is mixed by means of the sprayer plate 40 and as a mash by the mash pump 24 and the mash line 28 to a mash vessel (not shown) in the brewhouse?

Wenn das Malz im Silo 20 im wesentlichen aufgearbeitet ist, wird durch die Leitung 70 Spritzwasser in den Silo 20 eingeführt, um alle Rückstände auszuwaschen. Dieses Spritzwassei gelangt mit den Rückständen zu den Quetschwalzen und fließt teilweise über diese hinweg unter Umgehung des Quetschspaltes. Es können aber keine wesentlichen Mengen an Festbestandteilen über die Walzen 14 und 16 hinweggeschwemmt werden, einerseits dank dem stationären Leitblech 46, andererseits dank der Bemessung des schwenkbaren Leitblechteils 60, der sich mit seiner Unterkante 68 an den Umfang der Quetschwalze 14 anlegt, wenn Wasser in großen Mengen ankommt und wohl das Wasser, nicht aber das Malz in wesentlichen Mengen vorbeiläßt.When the malt in the silo 20 has essentially been worked up is, spray water is introduced into the silo 20 through the line 70 in order to wash out all residues. This splash water egg reaches the nip rollers with the residues and partially flows across this while bypassing the nip. But it cannot contain any significant amounts of Solid components are swept away over the rollers 14 and 16, on the one hand thanks to the stationary Baffle 46, on the other hand thanks to the dimensioning of the pivotable baffle part 60, which is with his Lower edge 68 rests against the circumference of the squeegee roller 14 when water arrives in large quantities and certainly lets the water by, but not the malt in substantial quantities.

An der der Sichtöffnung 54 zugekehrten Seite des beweglichen unteren Teils 60 des Leitbleches 48 ist ein Handgriff 72 angeordnet, der es gestattet, nach Abnahme des Deckels 52 von der Sichtöffnung 54 den beweglichen unteren Teil des Leitbleches 60 um annähernd 180° hochzuschwenken und dadurch Zugang und Sicht zu dem Quetschspalt 50 zu schaffen.On the side of the movable lower part 60 of the guide plate 48 facing the viewing opening 54 a handle 72 is arranged which, after removing the cover 52 from the viewing opening 54 the movable lower part of the guide plate 60 to pivot up by approximately 180 ° and thereby access and provide a view of the nip 50.

Eine Brückenbildung des dem Quetschspalt zuströmenden Malzes zwischen den Leitbiechen ist nicht möglich, weil der frei hängende Leitblechteil 60 ständig vibriert.There is a bridging of the malt flowing into the nip between the guide plates not possible because the freely hanging baffle part 60 is constantly vibrating.

Wie aus Fig. 2 ersichtlich, sind die Leitbleche mit Perforationen 71 versehen, welche das gequetschte Malz zurückhalten, Wasser aber durchlassen. Das Weichwasser kann deshalb, ohne daß Veränderungen an den Leitblechen vorgenommen werden müssen, sehr rasch abgeleitet werden.As can be seen from Fig. 2, the baffles are with Perforations 71 provided, which hold back the squeezed malt, but let water through. That Soft water can therefore, without having to make changes to the guide plates, can be derived very quickly.
