Popis: | Reproducible quality emulsions with high throughput are critical for a variety of specialized applications such as pharmaceutics and foods. In this work, we propose a simple and effective approach for producing highly stable, submicron sized, oil-in-water emulsions by high-shear, controlled turbulence in a confined impinging jet mixer using commercial-grade components and low molecular weight emulsifiers. Targeting the submicron range, food-grade oil-in-water emulsions in the 100 nm to 1 μm size range were produced by synergistically coupling multipass, jet-induced turbulence and ultrasonication effects to produce a throughput of up to 1.2 L/min. In addition, physiochemical effects of small molecule emulsifiers or surfactants and their formulations on drop breakup and stability were found to be important and were investigated to determine the optimal emulsifier deployment strategy. Other determining variables like magnitude and duration of local turbulence/energy dissipation and relative effects of compet... |
