Claim 0:
1. An atomizing device for use in an atomizing spray dryer comprising:
a liquid feed vessel having a liquid source providing a liquid, and an atomization exit;
a first transducer in proximity and downstream of the atomization exit, the first transducer disposed to define a gap between an outer edge of the liquid feed vessel and the first transducer;
a second stage, the second stage defined by a second transducer disposed in alignment with the first transducer for engaging an atomized liquid emerging from the atomization exit; and
a driver circuit connected to the first transducer and configured for driving the first transducer at an oscillation rate, the liquid from the liquid feed vessel flowing between the gap in communication with the first transducer for generating an atomization flow defined by formed by droplets of the atomized liquid.
