Abstract: An electrostatic spray drying system includes an electrostatic spray nozzle having a spray tip assembly arranged to discharge a supply of fluid into a drying chamber. The electrostatic spray nozzle is responsive to a duty cycle signal that determines periods at which the electrostatic spray nozzle is open to inject the fluid. A controller is programmed to activate a pulse width modulation (PWM) mode of operation for the electrostatic spray assembly, initiate a first timer, provide a first duty cycle signal to the electrostatic spray nozzle at a first PWM activation frequency while the first timer has not reached a first pulse duration, initiate a second timer when the first timer has reached the first pulse duration, and provide a second duty cycle signal to the electrostatic spray nozzle at a second PWM activation frequency while the second timer has not reached a second pulse duration.

Abstract: A spray drying system for drying liquid into powder including an elongated body and a closure arrangement at opposite upper and lower ends of the elongated body for forming a drying chamber within the elongated body. One of the closure arrangements including a drying gas inlet for introducing drying gas into the drying chamber. A spray nozzle assembly is supported in one of the closure arrangements. The lower end closure arrangement including a powder collection vessel for collecting powder dried in the drying chamber. The powder collection vessel is configured such that a blanketing gas may be directed into the interior of the powder collection vessel to blanket the powder in the powder collection chamber and thereby protect the powder from exposure to the drying gas from the drying chamber.

Abstract: A modular spray gun manifold having a plurality of spray gun modules arranged in a lateral array each separated by an adjacent support assembly. Each spray gun module has a central liquid passage communicating with a spray nozzle and a transversely oriented liquid inlet port communicating through an outer side of the spray gun module for connection with an independently controllable liquid supply. The spray gun modules further include a recirculation port communicating between the central passageway and a recirculation conduit in an adjacent support assembly. A control valve of each module is operable when in open spraying position for blocking communication of liquid from the central passageway to the circulation port and when in a valve closing position blocking the liquid flow to the spray nozzle while redirecting liquid from the liquid inlet to the recirculation port for recirculation through the manifold array.

Abstract: A spray dryer for drying liquid into powder including an elongated drying chamber, a spray nozzle assembly at an upper end of the drying chamber and a filter element housing and powder collection chamber at a lower end of the drying chamber. The filter element housing comprises a plurality of cylindrical filter elements supported from a wall of an exhaust chamber that communicates with an exhaust gas outlet of the filter element housing. In one embodiment, the filter element housing includes an inner downwardly opening cylindrical shroud surrounding the filter elements which defines an outer annular powder and drying gas passageway communicating with the powder collection chamber, and the exhaust chamber is defined by a downwardly opening conical plenum having an outer conical surface for directing drying gas and powder about the shroud into the powder collection chamber. Filter elements each have a respective reverse gas pulse cleaning device.

Abstract: A fluidized bed coating system for coating substrate particles with liquid and powder. The system includes a vessel having a particle separating partition that divides an internal chamber of the vessel into up-bed and down-bed regions. An upstanding spray nozzle within the particle separating partition for directing pressurized coating liquid upwardly into the up-bed region such that particles are liquid coated as they circulate through the up-bed and down-bed regions. A coating powder directing system is provided that includes a controller managed powder delivery manifold for directing coating powder and pressurized gas under the particle separating partition and below the discharge orifices of the spray nozzle for coating the liquid coated particles with a uniform thickness of coating powder as they are recirculated through the up-bed and down-bed regions.
