Abstract
A quad-centric nozzle and system for hydrocapsule encapsulation is disclosed. In at least one embodiment, a quad-centric nozzle is disclosed for encapsulating discrete droplets of liquid by generating a continuous coating or layer of a polymerizable liquid which is substantially immiscible with the core liquid. In at least one embodiment, the quad-centric nozzle includes: a material feed port assembly, a polymer feed port assembly, a first water feed port assembly, a second water feed port assembly and an encapsulated material exit port assembly. In at least one embodiment, the quad-centric nozzle is configured for use in a system for hydrocapsule encapsulation having a pressure control system, a water control system and sparging column, and an ultraviolet exposure chamber system.
