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.

An apparatus for drying, roasting, and cooling loose products includes a housing; a roaster drum configured to receive the loose products; a heat source disposed in an interior of a heat exchange chamber and configured to heat a gas circulated through the housing; a gas distribution grid reversibly coupled to a bottom of the roaster drum; a tilting hatch disposed below the gas distribution grid and configured to rotate between a raised position when the gas distribution grid is coupled to the bottom of the roaster drum and a lowered position when the gas distribution grid is uncoupled from the bottom of the roaster drum; an insulated channel configured to allow air to circulate from the heat exchange chamber to the gas distribution grid; and a cooling table configured to receive and cool the loose products, wherein the tilting hatch in the lowered position allows the loose products to slide down the gas distribution grid.

A process for torrefaction of biomass is provided in which biomass are passed into a fluidized bed reactor and heated to a predetermined temperature in an oxidizing environment. The dried biomass is then fed to a cooler where the temperature of the product is reduced to approximately 100 degrees Fahrenheit.
