Patent ID: 7171974

Claim:
A production apparatus of silver halide photographic emulsion, which performs a nucleus forming process, a nucleus growing process, a chemical sensitizing process or a spectral sensitizing process, comprising: a first liquid guiding pipe that collects process liquids processed by using plural microreactors for performing the nucleus forming process, and thereafter feeds the liquids to a next process; a second liquid guiding pipe which is connected to the first liquid guiding pipe for distributing and supplying the process liquids to plural microreactors which has a processing capacity equivalent to all of the processing capacities of the plural microreactors for performing the nucleus forming process for performing the nucleus growing process; a third liquid guiding pipe which collects the process liquids processed by using the plural microreactors for performing the nucleus growing process, and thereafter feeds the process liquids to a next process; and a fourth liquid guiding pipe for distributing and supplying the process liquids for the chemical sensitizing process or the spectral sensitizing process to plural microreactors.
