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: An electrostatic spray dryer for drying liquid into powder including an elongated body defining a drying chamber, a spray nozzle assembly at one end of the drying chamber and a filter element housing and powder collection chamber at an opposite end. A non-structural non-metallic liner is disposed within the elongated body in spaced relation to an inner wall surface for defining an internal drying zone. The liner is releasably supported within the body for enabling selective removal and replacement following a particular usage. The illustrated elongated body has a modular construction comprising a plurality of modules, with at least one being selectively removable and replacement for altering the length of the drying chamber for a particular spray application. The liner also is replaceable with a liner of a length corresponding to the altered length of the drying chamber or with a different diameter for a particular usage.

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.
