Abstract:
1. A method for producing an emulsion, comprising the steps of: providing at least a fluid to be processed that forms continuous phase and a fluid to be processed that forms dispersed phase, wherein said fluid to be processed that forms continuous phase and said fluid to be processed that forms dispersed phase are kept in independent states respectively; providing flow paths for feeding said fluid to be processed that forms continuous phase and said fluid to be processed that forms dispersed phase, said flow paths being independent of each other; providing at least two processing surfaces arranged to be opposite to each other, said two processing surfaces being configured to be capable of approaching to and separating from each other, at least one of said two processing surfaces rotating relative to the other; and mixing said fluid to be processed that forms continuous phase and said fluid to be processed that forms dispersed phase through their corresponding independent flow paths in a thin film fluid formed between said two processing surfaces, whereby the emulsion having variation coefficient of 0.3 to 30% in a particle size distribution is obtained, wherein the independent flow paths are provided with a first flow path and a second flow path, and the second flow path is formed through one of said at least two processing surfaces and leads to a space between the at least two processing surfaces, and wherein the second flow path through one of said at least two processing surfaces is positioned radially outward of the first flow path and is inclined with an angle at more than 0° and less than 90° to one of said at least two processing surfaces.
