Oil-In-Water Emulsification Using Oscillatory Micro-Screen, Jiangshan Liu

Electronic Thesis and Dissertation Repository

A novel emulsification technique has been developed for high throughput production of uniform emulsion droplets using high porosity oscillating stainless steel wire woven micro-screen. Different surfactants were investigated including dispersed/continuous bi-surfactant systems using Span80/SDS and Span80/Tween20. The effects of oscillation amplitude and frequency as well as the dispersed phase flux on emulsion average droplet size and uniformity were investigated. It was found that the droplet average size decreased with increasing the surface sheer stress. The emulsion droplet uniformity determined using the coefficient of variation (CV) changed with oscillations such that there was an optimal oscillating frequency for each amplitude where …
