ABSTRACT:
Disclosed is an evaporator apparatus and method for encapsulating individually isolated particles with a coating material wherein uniformally sized droplets, normally having no more than one particle, are formed from a mixture of the coating material, the suspended particles, and a carrier liquid; the droplets then being charged, steered by an electrostatic arrangement of a tubular electrode and at least one other electrode so as to be retained in a temperature controlled, predetermined area for a sufficient time period to allow the complete evaporation of the carrier liquid.
