Abstract

Ein Verfahren und eine Vorrichtung zum Trocknen von Loch­ ziegelrohlingen, bei denen Trocknungsluft auf die die Loch­ mündungen aufweisenden Stirnflächen der Rohlinge (54) geblasen wird, um eine Durchströmung der Lochkanäle zu bewirken. Zur Aufrechterhaltung einer intensiven Durchströmung der Lochkanäle ist vorgesehen, daß die Rohlinge (54) in einer einzigen, quer zur Durchströmungsrichtung gerichteten Schicht, vorzugsweise in einer Horizontalschicht, angeordnet sind. Die Blasvorrichtung (80) zur Förderung der Trocknungsluft weist mit Luftdurchtrittsöffnungen versehene Teile (82) auf, die an den beiden Seiten der Schicht, an denen die Lochkanalmündungen freiliegen, angeordnet sind. Dabei wird Trocknungsluft in stets gleichbleibender Richtung, aufgrund einer entsprechenden Anordnung von Umlenkschächten (82) ggf. in bestimmten Bereichen alternierend, durch die Lochkanäle geblasen. A method and apparatus for drying holes brick blanks, where drying air on the the hole blown end faces of the blanks (54) to cause a flow through the perforated channels. To maintain an intensive flow of the Hole channels are provided that the blanks (54) in one single layer directed transversely to the flow direction, are preferably arranged in a horizontal layer. The blowing device (80) for conveying the drying air has parts provided with air passage openings (82) on the two sides of the layer where the Hole channel mouths are exposed, are arranged. Doing so Drying air in a constant direction, due to a corresponding arrangement of deflection shafts (82) if necessary alternating in certain areas through the perforated channels blown.
