Abstract

See full text

An atomizing spray dryer employs one or more stages defined by ultrasonic transducers in close proximity to a liquid feed opening forming a path of an atomization flow for producing uniform droplets from a close tolerance with the transducer. The atomization flow exits a gap between the transducer and an outer edge of the opening, such that the passed liquid is responsive to an oscillation of the transducer for forming the droplets. A conical or other suitably shaped transducer engages a substantially round liquid feed opening. Subsequent stages may include a circular, ring, or other suitable shape aligned to receive the atomization flow from a circumference of the conical base, or may also take any suitable shape, preferably to receive droplets directed by the first stage.
