Abstract
PURPOSE:To improve quality of coating attained by a coating device, by removing dissolved air and fine foams contained in a photographic silver halide emulsion before applying the emulsion. CONSTITUTION:A photographic silver halide emulsion 18a is supplied from an inlet 11a of a deaerating.defoaming device 8 and introduced into a space between a module 9 constituted of many tubes comprising porous high molecular film and a housing 10. The emulsion flows along the outside of the tubes and reaches an exit 11b. An end of the module 9 is open at an air exhausting pipe 14, and another end is closed maintaining the inside of the tubes at a desired degree of vacuum with a vacuum pump 15. Thus, the dissolved air and fine foams are removed from the emulsion before the emulsion reaches the exit 11b. Temp. controlling liquid 19 for keeping the temp. of the emulsion between the outside of tubes and the housing 10 is supplied from an inlet 13a of the emulsion to a jacket 12.
