Abstract
A core/sheath vibrating system is utilized to produce core droplets within the sheath, which in turn form into microparticles through phase separation. The flow momentum is first arrested by means of an inclined surface, and the combination is thence deposited, in a continuous, helical channel extending from one end to the other of the inside of a hollow, rotating drum. Rotation of the drum moves the forming microspheres through the channel. At the exit end of the drum, the sheath fluid which carries suspended microspheres, may be filtered, and the microspheres collected and utilized.
