For processing matter in a turbulent mass of particulate material, a substantially annular processing region (14; 104; 206) is provided and is preferably in the form of a substantially annular processing chamber having a radially inner wall which includes a waist (38; 122). A flow of fluid and matter to be processed are admitted to the processing region through one or more inlets (28, 46; 108, 124; 214, 220) with the flow of fluid being directed generally circumferentially into the processing region. In the processing region, matter to be processed is embedded in a compact turbulent band of particulate material for processing. Once processing is complete, the processed matter is withdrawn from the processing region, preferably by entrainment in an exhaust flow of the fluid.

Apparatus for processing matter in a turbulant mass of particulate material, said apparatus comprising: means defining an annular treatment zone with a gas inlet means into said treatment zone; angled vane means for providing a swirling pattern of gas flow in said annular treatment zone which is expanded upwardly from said vane means towards center of said zone; a particulate inlet means for introducing a mass of particulate material into said treatment zone in such a manner so as to entrain said particulate matter in said swirling flow; said treatment zone having a shape to maintain said mass of particulate material substantially in a compact turbulent band within said treatment zone in response to said flow of gas and at least one opening for outlet of said gas and particulate material.
