Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a finely divided and stable solid dispersion which can maintain the wear of a dispersion device at the minimum, minimize the charge of impurities due to the wear, and easily and economically isolate dispersion.
SOLUTION: At least two streams of predispersion are each sprayed onto a collision point in a reaction chamber enclosed by a reactor casing, through separate nozzles by using a pump, preferably a high-pressure pump. Water vapor is charged into the reaction chamber through an opening so that the reaction chamber is occupied with a vaporous atmosphere mainly consisting of the water vapor. Finely divided dispersion and water vapor mainly consisting of water and/or partially condensed vapor are removed from the reaction chamber by excess pressure of the water vapor charged at a gas inlet side.
