  • Method and an apparatus for the processing of photographic sheet material
    Patent number: 5568693
    Abstract: An apparatus for the processing of photographic sheet material having upstream and downstream drying chambers (101, 102). A heater (106) heats air entering the downstream chamber (102) to a downstream drying temperature. A fan (108) recirculates drying air from the downstream chamber (102) through the heater (106) while taking in fresh air through an inlet (116). A heater (110) heats air entering the upstream chamber (101) to a temperature higher than the downstream drying temperature. A fan (112) recirculates air from the upstream chamber (101) through the heater (110) while taking in air from the downstream chamber (102). Optimum drying of the sheet material is thereby achieved without risk of dimensional instability.
