Title:
EMULSIFYING METHOD AND DEVICE
Document Type and Number:
Japanese Patent JP3242776
Kind Code:
B2
Abstract:
PURPOSE: To obtain an emulsion where loss volume has been decreased even for a small quantity and which is uniform and excels in stability by forcibly feeding a liquid for a dispersed phase into a flowing liquid for a continuous phase through a porous member to disperse it.
CONSTITUTION: A emulsifying vessel 11 is divided into a chamber for a liquid for a dispersed phase 13 and a chamber for a liquid for a continuous phase 14 by a porous member 12. The porous member is preferably that of 0.1-10 micron average pore diameter and is preferably a porous membrane in the form of a plate or a cylinder. The pressurization of the liquid for a dispersed phase in the liquid chamber 13 is performed through a line 26 communicating with a gas pressurizing source or by a pressurizing member, such as a piston. The liquid for a continuous phase in the liquid chamber 14 is agitated by a rotor 23, etc. In this way, the liquid for a dispersed phase is pressurized even for a small quantity of 1-10ml of the emulsified quantity. And also the liquid chamber 14 is provided with an introducing pipe 39 for the liquid for a continuous phase and an emulsion takeoff port to continuously produce an emulsion little by little. In this case, the liquid chamber 13 is preferably provided with an introducing pipe 32 for the liquid for a dispersed phase.
