Abstract: An electrohydrodynamic (EHD) drying apparatus includes a non-uniform electric field resulting from an electric field source operable for a high potential, and an electric field source operable for a low potential. A power source is connected to the electric field sources for producing the non uniform electric field for inducing dielectrophoresis (DEP) in an article within the uniform electric field. In particular configurations, the applied non-uniform electric field is for separating a vapor phase being formed during drying from the liquid phase. The electric field source defines a polarizer adapted to produce dielectrophoresis, and the electric field induces coupled electrostatics and momentum for disposing liquid towards the high electric field for drying.

Abstract: 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.
