A fluidized bed spray drying system for drying liquid into powder including an elongated drying chamber, a spray nozzle assembly at an upper end of the drying chamber and a powder collection chamber at a lower end of the drying chamber. A drying gas inlet is provided in the powder collection chamber and a drying gas outlet is provided at an upper end of the drying chamber. A plurality of cylindrical filter elements at the upper end of the drying chamber are in communication with the exhaust gas outlet for filtering drying gas borne powder from drying gas exiting the drying chamber.

Fluidized bed spray dryer system

A spray drying system for drying liquid into powder including a plurality of processing towers each including an elongated drying chamber, a spray nozzle assembly at an upper end of the drying chamber and a powder collection chamber at a lower end of the drying chamber. The powder collection chamber of each processing tower being configured to discharge power to a common conveyor system.

Modular spray dryer system

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.

Apparatus and method for spray drying

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.
