Abstract:
A method for producing atomized liquid, comprising the steps of:forcing a first liquid through a channel of a first feeding source in a manner which causes the first liquid to be expelled from a first exit opening; forcing a second liquid through a second channel concentrically positioned around the first channel in a manner which causes the second liquid to be expelled from a second exit opening; forcing a gas through a pressure chamber in a manner which causes the gas to exit the pressure chamber from an exit orifice in front of a flow path of the first and second liquids; wherein the first liquid and the second liquid are immiscible and the second liquid surrounds the first liquid forming concentric streams which are focused to a stable jet with a stable first liquid-gas interface which flows out of the exit orifice of the pressure chamber; and allowing the stable jet of concentric streams to exit the pressure chamber surrounded by the gas and break up outside the pressure chamber and form spherical coated particles comprised of the first liquid coated with the second liquid.
