PURPOSE:To finely pulverize an emulsified grain and to make the grain size fine by emulsifying and dispersing an aq. phase and an oily phase with an apparatus which is provided with both members of a member rotating along an inside wall and/or a bottom of an emulsification dispersion apparatus and a high-velocity stirring member rotating in high velocity. CONSTITUTION:An aq. phase and an oily phase are respectively dissolved and prepared by using the preparation kettles 1, 2 (or a close-type emulsification dispersion apparatus 3 is used instead of one hand thereof.) of the aq. phase and the oily phase provided with the propeller type stirrers. Both the prepared phase are transferred into the apparatus 3, emulsified and dispersed for a speci fied time by rotating the high-velocity stirrers 8, 9 so as to reach >=2500cm/ second circumferential velocity. Furthermore in this time, the inside of the apparatus 3 may be made to a decompression state with a vacuum pump 7 in order to remove a low b.p. solvent or to suppress the bubbles. In this time, the temp. of the inside of the apparatus 3 is always held at about 50-70 deg.C with a hot water jacket 6. |
