Abstract:
A method of producing microcapsules of the type having a core and a coating encapsulating the core comprises the steps of providing a core-forming fluid stream and a coating-forming fluid stream, providing a two spray nozzle arrangement having a core nozzle disposed concentrically about a second nozzle, spraying the core-forming fluid stream from the core nozzle and the coat-forming fluid stream from the concentric nozzle to produce microcapsules, and solidifying the microcapsules upon formation in a suitable gas. Spray drying or spray chilling may be employed as the means of solidifying the microcapsules. Microcapsules having a core and a solid coat are also described.
