Abstract
An emulsion of a disperse phase liquid in a continuous phase liquid is produced by atomizing the disperse phase liquid electrostatically and entraining the atomized droplets in a moving layer of continuous phase liquid. To produce a spray with atomized droplets of small and uniform size a disperse phase liquid, such as wax in a solvent, is directed to flow over the sharp edge of a blade maintained at a high voltage with respect to the conductive surface of the drum. The drum is rotated so that the surface is wetted by a reservoir of continuous phase liquid and so that the surface layer of liquid intercepts the spray of droplets at a uniform rate to produce an emulsion of consistent concentration. The concentration is controlled by setting the rates of flow and the number of cycles of interception.
