Abstract: The present invention provides a method of efficiently manufacturing an emulsion that is improved in monodispersibility by a membrane emulsification method. The manufacturing method for an emulsion of the present invention includes circulating a mixed liquid containing a water phase and an oil phase in a circulation circuit including one or more tanks, a porous body, liquid-delivering means, and circulation pipes configured to connect the tanks, the porous body, and the liquid-delivering means so that the mixed liquid passes through the porous body a plurality of times, wherein the circulation circuit further includes a gas-separating device, and wherein the gas-separating device is configured to remove air bubbles from the mixed liquid therethrough.

Abstract: The present invention provides a method of manufacturing an emulsion that is more excellent in monodispersibility by a membrane emulsification method. The manufacturing method for an emulsion of the present invention is a manufacturing method for an emulsion, including circulating a mixed liquid containing a water phase and an oil phase in a circulation circuit including a plurality of tanks, a porous body, a liquid-delivering means, and circulation pipes configured to connect the tanks, the porous body, and the liquid-delivering means so that the mixed liquid passes through the porous body a plurality of times, wherein a tank to supply the mixed liquid to the circulation pipes toward the porous body and a tank to recover the mixed liquid that has passed through the porous body are different tanks.
