In the future, the innovation will be widely used in a range of industries, from food processing and health products to cosmetics, to capsule drug delivery research and development. Previously, researchers from Flinders University and the University of California, Irvine, used VFD to turn boiled eggs back to "raw eggs" in experiments. They use a chemical to liquefy the protein of cooked eggs, and then use a vortex jet device to cut off the tightly entangled protein molecular chains to make them reconstruct normally. This time, they still used this device to uncover the mystery of immiscible liquid. This new progress may improve many products, industrial processes and even the food we consume in the future. Professor Colin Ruston, senior author of the paper and professor of the Institute of nanoscience and technology at Flinders University, said that they now demonstrated the process by using "ordinary solvents and water", while avoiding the use of other substances to regulate the reaction of immiscible liquids, making the process more environmentally friendly and cleaner. The researchers said that thin film microfluidic technology combined with "high shear flow chemistry and high heat and mass transfer", and the rapid development of VFD technology is overcoming the mixing limitations of traditional treatment. It is understood that researchers have conducted more than 100000 experiments to determine the mixing mode of liquids and their flow behavior on a very small nano scale. More importantly, researchers at Flinders University have also expanded the size of VFD machine and used it for experimental biodegradable polymers to start large-scale production of its organic substances and develop clean technologies in order to adapt to the application of a series of industries. In essence, VFD has been used in many experiments to produce high-quality pharmaceutical elements, such as peptides, fish oil and food, as well as many other green chemical processes.
