Abstract: Method of and apparatus for emulsification of oils assuring obtaining the desired dispersion and stability of emulsions.Vibration action is applied to cells containing water and oils so as to subject the cell and their contents to energy impulses varying in accordance with sine curves, thereby dispersing oil into fine drops which are evenly distributed throughout the system. The apparatus includes a plurality of serially mounted emulsion cells forming a unitary closure, the closure being mounted on a fixed support through springs. A vibration device is mounted upon the enclosure so as to vibrate it as described. Between the successive cells in the enclosure there are disposed grids or sieves, and vibration actuated valves having valve elements which function somewhat in the manner of diaphragm pumps.
