ABSTRACT:
An emulsifying device and method for obtaining emulsion by agitating mixed liquid having both dispersion liquid and disperse medium, includes an emulsifying body consisting of an outer cylinder and an inner cylinder positioned at an uniform clearance therebetween. The mixed liquid is applied to the clearance from an inlet positioned at one end of the circumference side of the outer cylinder, and discharged from an outlet positioned at another end of the circumference side of the outer cylinder. The inner cylinder is rotated around the same axis of the fixed outer cylinder, in which the mixed liquid is sufficiently emulsified by an uniform shearing force along the longitudinal direction of the inner cylinder.
