Method for producing microparticles in a continuous phase liquid
First Claim
Patent Images
1. A method of producing microparticles, comprising:
- (a) providing a co-flow channel having upstream and downstream ends;
(b) causing a dispersed phase liquid to flow into a flowing body of a continuous phase liquid at the upstream end of the co-flow channel, and allowing the dispersed phase liquid to flow into the co-flow channel together with the continuous phase liquid, wherein the dispersed phase liquid is sheathed by the continuous phase liquid within the co-flow channel; and
(c) comminuting the continuous phase and dispersed phase liquids in the co-flow channel by intermittently moving a comminuting unit transversely into the co-flow channel to block the co-flow channel at intervals, wherein the microparticles of the dispersed phase liquid are formed within the continuous phase liquid.

Abstract
A continuous phase liquid and a dispersed phase liquid are permitted to flow together through a co-flow channel. Preferably, the dispersed phase liquid is arranged to flow within the flowing body of the continuous phase liquid in the co-flow channel so that the dispersed phase liquid is sheathed by the continuous phase liquid. The continuous phase and dispersed phase liquids are comminuted into microparticles in the co-flow channel by intermittently blocking the co-flow channel.
