ROTARY TYPE MICROCHANNEL EMULSIFICATION METHOD, DEVICE FOR PERFORMING THE SAME AND PREPARED EMULSIFIED SUSPENSION AND PARTICULATE

摘要

PROBLEM TO BE SOLVED: To provide a rotary type microchannel emulsification method for stably preparing particulates having uniform particle diameters, and to provide a rotary type microchannel emulsification device for performing the method.;SOLUTION: In the rotary type microchannel emulsification method where particulates having uniform particle diameters are stably prepared, (1) a circular substrate having at least one or more optional flow passage patterns with a width of 1 to 1,000 μm and a depth of 1 to 1,000 μm is comprised, (2) extrusion or centrifugal force is acted on each flow passage in the circular substrate from the vicinity of the center of the circular substrate, thus at least one or more kinds of fluids are made to flow to a radial direction, (3) the vicinity of the center in the circular substrate is provided with an inlet structure, each passage edge or intermediate part is provided with an outlet part, and each fluid passed through each passage is contacted with the external fluid at the outlet part, and (4) the circular substrate or sidewall is rotated at a rotational speed of 0 to 5,000 mm/s, and high shearing can be uniformly applied to all the fluids made to flow out from the plurality of passage edges.;COPYRIGHT: (C)2006,JPO&NCIPI
