Development of Microchannel Emulsification Technology

Development of Microchannel Emulsification Technology for Monodispersed Soybean and Olive Oil-in-Water Emulsions

Emulsions are widely used in food industry, among others. Monosized droplets in emulsions have advantages for control of their properties, and application fields. We have developed microchannel emulsification (MC) technology for monosized droplets formation. The grooved type MC and module were used to characterize MC emulsification, and straight-through MC and module were developed for higher p...

Microchannel Emulsification Technology for Production of Monosized Droplets, Microcapsules, and Microbubbles

An emulsion consists of small, spherical droplets of one of two immiscible liquids in the continuous phase of the other. Emulsion droplets usually have an average diameter in the range of 0.1-100 μm. Monodisperse emulsions are useful for measuring, analyzing, and controlling many of their important physical, physicochemical, and organoleptic properties. Monodisperse-emulsion-based materials (e....

High-Performance Microchannel Emulsification Device with Microfabricated Asymmetric Through-Holes

Oil-water de-emulsification using ultrasonic technology.

In this paper an oil-water de-emulsification process within large tanks using ultrasonic technology is presented. As the device would operate in hazardous areas, it should not consume an excessive amount of electrical power. Hence, the paper investigates the suitable oil-water concentrations (10-90% concentrations in step of 10%) which would lead to the fastest separation while consuming the mi...

Continuous synthesis of drug-loaded nanoparticles using microchannel emulsification and numerical modeling: effect of passive mixing

By using interdigital microfluidic reactors, monodisperse poly(d,l lactic-co-glycolic acid) nanoparticles (NPs) can be produced in a continuous manner and at a large scale (~10 g/h). An optimized synthesis protocol was obtained by selecting the appropriated passive mixer and fluid flow conditions to produce monodisperse NPs. A reduced NP polydispersity was obtained when using the microfluidic p...
