Patent ID: 7718099

Claim:
A method, comprising: providing a fine channel including an inlet port and an inlet channel which feed a dispersion phase, an inlet port and an inlet channel which feed a continuous phase, and an outlet channel and an outlet port which discharge fine particles produced by the dispersion phase and the continuous phase, the inlet channel for feeding the dispersion phase and the inlet channel for feeding the continuous phase are joined directly such that the directions of the lengths of said inlet channels form a first angle, said two inlet channels are connected directly to the outlet channel, at least one of said two inlet channels is connected directly to the outlet channel such that the directions of the lengths of said outlet channel and said at least one of inlet channels form a second angle, wherein the first and second angles are such that the inlet channels and outlet channels exhibit a Y-letter shape, and a projection extends into the outlet channel where the inlet channel for feeding the dispersion phase and the inlet channel for feeding the continuous phase are joined to the outlet channel; providing the dispersion phase through the inlet port which feeds the dispersion phase and providing the continuous phase through the inlet port which feeds the dispersion phase such that the outlet channel discharges the fine particles produced by the dispersion phase and the continuous phase; and emitting energy into the outlet channel such that the energy hardens at least a surface of the fine particles.
