PURPOSE:To enable the reutilization of a rinsing liquid by blowing the waste heat air of a drying section to a waste liquid housed therein to evaporate the waste liquid, then introducing the low-humidity air dried on cooling of the vapor thereof into the drying section, thereby executing the drying of a photosensitive material and processing of the rinsing liquid. CONSTITUTION:The rinsing liquid overflowing from a rinsing layer 12 is fed as the waste liquid and is housed into a waste liquid tank 23. Since the lower part of an evaporating medium is immersed in the waste liquid tank 23, the medium stuck with the waste liquid moves. The air heated in a heater 45 and the waste heat air of the drying section 30 are blown to this evaporating medium to evaporate the moisture in the waste liquid sticking thereto. The air contg. the moisture is cooled in a cooler 30 and is returned to the rinsing tank 12. The heat in the waste air in the drying section 30 is blown to the evaporating medium. The moisture in the waste liquid is thereby absorbed in the system by evaporating the same and is reutilized. On the other hand, the air cooled in the cooler 30 is dehumidified by dew condensation. The high-temp. air of the extremely low humidity is obtd. at the point of the time when said air is heated by a heater provided in the drying section. Efficient drying is thus executed. |
