Abstract
In an apparatus for continuously manufacturing microspheres, a dispersed phase (O) is supplied to a chamber,for the dispersed phase inside of a bulkhead member,via a supply port,. Thereafter, the dispersed phase enters into a gap,between a plate,via a supply port,in a base,. The dispersed phase which enters into the gap,grows microspheres (particles) having a certain diameter while passing through a microchannel,by pressure applied by, for example, a pump, and is mixed with a continuous phase (W), so that microspheres are produced. The thus-produced microspheres float or are suspended in the continuous phase without needing any particular external force in response to their specific gravity, allowing the microspheres to be generated and withdrawn from a withdrawal port 32 at a significantly reduced pressure in comparison to conventional methods and apparatus.
