Title: Cooling method for photographic processing solution
Inventor: SAI RIYUUICHI
IPC: G03C5/31
Filed: 1978-09-30
Abstract: PURPOSE:To enable water to be saved and yet make selection and moving of the location of the photographic processing machine easy by accelerating the evaporation of the photographic processing solutions and cooling the photographic processing solutions through utilization of the latent heat of evaporation. CONSTITUTION:Since respective photographic processing solution cells 1, 2, 3 are of thin type shape with opened top, the photographic processing solutions in the respective cells are easier to evaporate. Even more, they are covered with a cover 9 and therefore the vapors become saturated. Thereupon, the wet air V having saturated is exhausted to the outside through gas exhaust port by a fan 8. As a result, the photographic processing solutions in the respective photographic processing cells 1, 2, 3 are accelerated of evaporation and are cooled by the latent heat of evaporation. In contrast with this, the photographic processing solutions become liable to be oxidized and since this degrades the finish of photographs, there is a need for setting various conditions such as photographic processing solution amounts, photographic processing cell surface areas, processing solution temperatures, etc. that are capable of withstanding oxidation and practicable use.
