Claims (6)
- Vorrichtung zum Trocknen von fotografischem Material (2) von einem Ist- bis zu einem Soll-Feuchtigkeitsgehalt, wobei die Vorrichtung folgende Komponenten umfaßt:- eine Heizeinrichtung (4, 4′) zum Erwärmen mindestens einer Seite des Materials (2), wobei die Heizeinrichtung ein erstes Heizaggregat (4) und ein zweites Heizaggregat (4′) aufweist;- einen Sensor (14) zum Messen des im Material (2) nach Durchlaufen des ersten Heizaggregats (4) verbliebenen Feuchtigkeitsgehalts; und- eine Steuerungseinrichtung (24) zum Steuern des zweiten Heizaggregats (4′);dadurch gekennzeichnet, daß die Heizeinrichtung (4, 4′) aus Infrarot-Wärmequellen besteht, die so angeordnet sind, daß das zu trocknende Material direkt vom ersten Heizaggregat (4) zum zweiten Heizaggregat (4′) bewegt wird, und daß der Sensor (14) ein Ausgangssignal an die Steuerungseinrichtung (24) liefert, welche die zum Erreichen des erwünschten Soll-Feuchtigkeitsgehalts vom zweiten Heizaggregat (4′) noch zu erbringende Trocknungsleistung steuert.
- Vorrichtung nach Anspruch 1, gekennzeichnet durch Ventilatoren (6), die auf mindestens eine Seite des Materials (2) Luft blasen, wobei die Ventilatoren (6) durch die Steuerungseinrichtung (24) gesteuert werden.
- Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß der Sensor (14) ein kapazitiver Sensor ist.
- Vorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß der Sensor (14) ein Leitfähigkeits-Berührungssensor ist.
- Vorrichtung nach einem der vorhergehenden Ansprüche, gekennzeichnet durch einen weiteren, den Restfeuchtigkeitsgehalt des Materials (2)) messenden Sensor (22).
- Vorrichtung nach einem der vorhergehenden Ansprüche, dadurch gekennzeichnet, daß das Material (2) bandförmig ist oder aus Einzelblättern besteht.
