Abstract
The invention is directed to production of particles for introduction into food using a stable microjet and a monodisperse aerosol formed when the microjet dissociates. A variety of devices and methods are disclosed which allow for the formation of a stream of a first fluid (e.g. a liquid) characterized by forming a stable capillary microjet over a portion of the stream wherein the microjet portion of the stream is formed by a second fluid (e.g. a gas).
Claims10
A method for producing a food product, comprising the steps of:
- forcing a liquid food through a channel of a feeding source in a manner which causes the liquid to be expelled from an 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 down stream of a flow path of the liquid expelled from the exit opening of the feeding source;
- wherein a stable first liquid-gas interface is maintained and the liquid forms a stable jet focused on the exit orifice of the pressure chamber by the gas;
- and wherein said jet dissociates into particles after expulsion from the exit opening, said particles having the same diameter with a deviation of about ±3% to about ±30%.

A method for producing encapsulated particles, 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 an exit opening;
- forcing a second liquid through a channel of a second feeding source in a manner which causes the second liquid to be expelled from an exit opening, wherein said second liquid surrounds said first liquid as said first liquid moves from the first feeding source;
- and
- forcing a gas through a pressure chamber in a manner which causes the gas to exit the pressure chamber from an exit orifice down stream of a flow path of the first and second liquids expelled from the exit opening of the feeding sources;
- wherein a stable liquid-gas interface is maintained between the second liquid and the gas, and the first and second liquids are immiscible and form a stable capillary jet focused on the exit orifice of the pressure chamber by the gas.
