PURPOSE: To improve the quality of photographing emulsion and to improve the efficiency of storage by storing the photographing emulsion accumulated in a loadable/ unloadable case in a vacuum sealed room kept at a sol/gel transfer point of the emulsion, dispersing supercooled emulsion sol and gelling the emulsion sol by using the latent heat of evaporation due to boiling.
CONSTITUTION: The degree of vacuum in the vacuum sealed room 1 storing the loadable/unloadable case 4 is adjusted at the sol/gel transfer point of the photographing emulsion, the emulsion is dispersed from the upper part of the sealed room 1 into the case 4 as supercooled sol and gelling the sol by using the latent heat of evaporation due to boiling to obtain gelled photographing emulsion in the case 4. Since the emulsion stored in the case 4 is gelled by using the latent heat of evaporation due to boiling, dispersion in the distribution of silver or the generation of fogging is prevented. The emulsion is stored in a uniform surface and the storage efficiency is improved. In addition, the method is suitable for the production of small quantity of many kinds of emulsion because each case 4 is divided. The dispersed emulsion drops 10 are guided by a drop growing pipe 8, dropped while colliding with each other, and mixed with steam flow at the dispersed moment, so that the emulsion drops 10 are not lost in an exhaust system.
