A fluidized bed system is a single unitary modular system that packages a circulation fan, a fluidized bed, and a dust collection system within a same structure. The structure is formed to include internal ducts to provide fluid communication between the circulation fan, the fluidized bed, and the dust collection system. The fan provides a flow of air via a pressure duct to the fluidized bed. Particulate is separated from particles included on the fluidized bed by the flow of air being uniformly distributed to the fluidized bed. Particulate separated in a disengagement area and suspended in the flow of air is conducted through a particulate clearance space surrounding the dust collection system. The particulate is captured by the dust collection system and conveyed to a location external to the system.

A method for automatically collecting and analyzing data from a plurality of industrial equipment includes automatically establishing communication between sensor nodes of the plurality of equipment and a walk-in device in response to the walk-in device entering a data collection area in a facility associated with the plurality of electrical equipment. The method also includes determining if the walk-in device is an authorized device to collect data from the plurality of industrial equipment and, in response to determining the walk-in device is an authorized device, automatically collecting select data from the plurality of industrial equipment on the walk-in device. The collected data is processed and one or more actions are performed based on the collected data.

The process comprises delivering a spray solution comprising an active agent and a matrix material in an organic solvent to a spray-drying apparatus, atomizing the spray solution into droplets within the spray-drying apparatus to remove at least a portion of the organic solvent from the droplets to form a plurality of particles, and collecting the particles. The spray solution may be formed by forming a feed suspension comprising the active agent, the matrix material, and the organic solvent, wherein the feed suspension is at a temperature T.sub.1, and directing the feed suspension to a heat exchanger, thereby increasing the temperature of the feed suspension to a temperature T.sub.2, wherein T.sub.2 is greater than T.sub.1, and the spray solution is at a pressure greater than the vapor pressure of the organic solvent at T.sub.2, such that the active agent and matrix material are soluble in the organic solvent at T.sub.2.
