Development of Continuous Emulsification Using New Type Emulsifier

Abstract

Abstract A continuous emulsification apparatus, which was a column type mixer with vibration plates, is developed. The characteristics of emulsification using the emulsifier are investigated under various experimental conditions. The mean residence time and volume fraction of dispersion phase have almost no effect on average diameter and variance of the emulsion prepared. It is found that the average diameter and it's variance are determined by the frequency and ratio of space area between the vibration plates and cross-section of the emulsifier (R). The average diameter of the emulsion is formulated as a function of the frequency and the ratio of space area at constant values of mean residence time and volume fraction of dispersion phase as following equations.

a_W/O=6.95×105R+0.55, b_W/O=-1.43
