An apparatus and process for producing liquid droplets having a narrow size distribution. Thin liquid streams are forced under pressure through a plurality of orifices in an orifice plate, the largest of which orifices has a diameter not greater than about three times the diameter of the smallest of those orifices. Also the thin liquid streams are vibrated to cause the breakup of each stream into droplets having a narrow size distribution.
