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.
