초록 ▼

Cross-flow microchannel apparatus for producing emulsions includes a pump 9 and a pump 11 which are driven to respectively supply a continuous phase to a concave portion 4 via a supply pipe 10, a supply hole 6 and a supply port 18 and a dispersed phase to a space between the outside of a base 3 and the inside of a concave portion 2 formed in a case 1 via a supply pipe 12 and a supply hole 7. Then, by applying a predetermined pressure to the dispersed phase, the dispersed phase is formed into fine particles via a microchannels 21 and mixed with the continuous phase, thereby forming emulsions. The emulsions are withdrawn to a tank and so on via a withdrawal port 19, a withdrawal hole 8, and a withdrawal pipe 13 for emulsions. The apparatus can alternatively be used to separate an emulsion by pumping the emulsion within the concave portion 4 via pipe 10, hole 6 and port 18, such that the emulsion is separated via the microchannels 21 into a continuous phase that is withdrawn from the hole 7, and a dispersed phase that is withdrawn from the hole 8.

[ What is claimed is:] [1.]1. A cross-flow microchannel apparatus, comprising:a case;a base which is accommodated in said case; anda plate which is installed facing a side of said base for forming a flow path in said base; whereinsupply and withdrawal holes are formed in said case for supplying at least one of a continuous phase, a dispersed phase and an emulsion within the case and for withdrawing at least one of the continuous phase, the dispersed phase and the emulsion from said case;a supply port corresponding to one said supply hole, a withdrawal port corresponding to one said withdrawal hole and microchannels opening to the flow path are formed in said base; and furthermore, via the microchannels, a region within said case at the outside of said base and the flow path at the inside of said base are connected.
