ABSTRACT:
In manufacturing hollow particles, gas is supplied from a gas cylinder to a first tank under pressure for solution in a raw material liquid in the first tank for the particles. The resulting raw material liquid is supplied to a second tank where the liquid is stirred with a dispersing medium under pressure, thereby forming a compressed emulsion in the second tank. As the compressed emulsion is discharged to the outside, it is released from the compressed state so that the gas dissolved in corpuscles of the raw material liquid in the emulsion will come out as bubbles. Thus since the corpuscles in the emulsion become hollow particles, an emulsion containing fine hollow particles of the raw material liquid as nuclei is obtained. Therefore it is possible to obtain a large quantity of fine hollow particles with ease.
