Process and an apparatus for improving the properties of solutions having a high solids content, which are to be used for coating a tape particularly solutions of photographic emulsions
A process and apparatus for improving and maintaining the concentration, and homogeneity of gelatino silver halide emulsions with a high solids content reservoir bath for tape coating a photographic emulsion, wherein the coating emulsion is partly withdrawn from the bath and circulated through a known type of falling film evaporator to which a vacuum is applied and processed to concentrate, degasify and homogenize the withdrawn emulsion. A ballast steam under high velocity is injected into the falling film of emulsion to act on the emulsion.
