Abstract: In an apparatus 10, a space is formed by a pair of impermeable supports 16 and a pair of spacer members 12 for providing a predetermined distance between the impermeable supports 16. A permeable membrane is provided within the space and outlets 15 are provided on each of the pair of impermeable members 16. A stirrer 20 is provided within the space where the permeating object is present, and comprises a stirring axis 22, a driving source for oscillating the stirring axis 22, and a plurality of stirring blades 24 mounted on the stirring axis 22. Cut sections 26 are provided at a portion of each of the stirring blades 24 so that the permeating object can be circulated at the space between the stirring blade 24 and the inner wall of the spacer member 12 or at the space between the stirring blade 24 and the permeable membrane 14. The cut sections are alternately provided at the right and left sides of the layered stirring blades.

Abstract: A first dispersion phase is dispersed in a first continuous phase comprising a solidifying component so as to prepare a primary emulsion, and this primary emulsion s ispersed in a second continuous phase as a second dispersion phase so as to prepare a secondary emulsion. The solidifying component in the secondary emulsion is then solidified, and the first dispersion phase is removed leaving pores so as to form porous particles.
