These results indicate that homogenization is particularly efficient at forming small droplet sizes in emulsions, and droplet disruption in rotor-stator systems is generally less efficient than high-pressure devices. Because the dispersing zones of rotor-stator systems usually have larger volumes, at constant energy density and volume flow rate, the mean power density in rotor-stator systems is lower than that in the nozzles of high-pressure devices [21]. No matter how coarse the emulsion is, when it was passed through the same homogenization recirculation under the same homogenization pressures, the same fine levels in both PFAT5 and MDS can be attained. However, the rotor-stator system is still important because it can efficiently convert separate oil and water phases into macroemulsions with a fairly large droplet size to alleviate the wear and tear on the homogenizer. The Ultra Turrax model was widely used during emulsions preparation because it is simple to operate and it can produce a good dispersing effect at a low shear force.
