Abstract: An electrostatic spray dryer for drying liquid into powder including an elongated cylindrical drying chamber having an electrostatic spray nozzle at an upper end and a powder collection vessel at a lower end. The powder collection vessel includes a removable and replaceable filter collections sock made of filter material for receiving and collecting dried powder from the drying chamber. For cleaning residual powder from an inside wall of the drying chamber, a scraper member is provided that is coupled by magnetic attraction to a manually removable driver on the external surface of the wall.

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 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 translation: 一种模块化喷枪歧管，具有多个喷射模块，每个喷枪模块以横向阵列排列，每个由相邻的支撑组件分隔。 每个喷枪模块具有与喷嘴连通的中央液体通道和通过喷枪模块的外侧连通的横向取向的液体入口，用于与独立可控的液体供应连接。 喷枪模块还包括在相邻支撑组件中的中心通道和再循环管道之间连通的再循环口。 每个模块的控制阀在处于打开的喷射位置时可操作，用于阻止液体从中心通道到循环端口的连通，并且当处于闭合位置时阻挡液体流到喷嘴的流体，同时将液体从液体入口重定向到 用于通过歧管阵列再循环的再循环端口。

Abstract: A fluidized bed coating apparatus for coating liquid onto the surfaces of particles directed into a coating chamber. A liquid spray nozzle assembly disposed below a hollow separator within the coating chamber includes an ultrasonic atomizer for atomizing coating liquid into a fine liquid particle cloud and a pressurized air directing air cap for forming the ultrasonically atomized fine liquid particle cloud into a cone shaped spray pattern and propelling the liquid particles through the separator into an upbed region of the coating chamber for recirculation in an outbed region, and through the separator. A cooling air passageway system is provided within the spray nozzle assembly for cooing the ultrasonic atomizer during operation.
