1. An apparatus for producing emulsions by spraying particles of a disperse phase liquid into a continuous phase liquid, said apparatus comprising in combination:

  • (a) an emulsifying vessel interiorly providing a gravitiative flow surface for forming thereon a stream of said continuous phase liquid;

    (b) a continuous phase liquid feeder for directing said continuous phase liquid to said gravitative flow surface of said emulsifying vessel;

    (c) a rotary atomizing head disposed in said emulsifying vessel in communication with a disperse phase liquid supply;

    (d) a rotational drive means for rotatably driving said rotary atomizing head within said emulsifying vessel;

    (e) a high voltage power supply connected to said rotary atomizing head to apply thereto a high voltage to atomize said disperse phase liquid in cooperation with said rotational drive means and to direct electrostatically charged particles of said disperse phase liquid toward said gravitative flow surface of said emulsifying vessel along lines of electric force formed between said rotary atomizing head and said emulsifying vessel, thereby continuously dispersing the atomized particles of said disperse phase liquid in said stream of said continuous phase liquid; and

    (f) a receptacle located beneath said gravitative flow surface of said emulsifying vessel for collecting the resulting dispersion.
