Abstract (en)
[origin: EP2123349A2] There is provided an emulsification device for mixing two different liquids not dissolvable in each other, wherein (1) emulsion droplets can be reduced to micro size without reducing the channel width, which may cause degraded productivity; and wherein (2) a disperse phase can be prevented from adhering to the channel wall surface, thus allowing the device to be operated for a prolonged period of time and a uniform emulsion droplet size to be obtained. The emulsification device comprises: at least one channel (211) of a first liquid; a channel (210) of a second liquid; and a mixing channel (304) in which the first liquid is joined with the second liquid. In the mixing channel (304), the first liquid has a swirl component in the mainstream direction. The channel of the second liquid is connected to the central portion of the mixing channel, and the second liquid flows at the central portion of at least one swirl flow of the first liquid. In this way, at least one continuous-phase swirl flow is formed around the disperse phase.
