Abstract
A fluidization process, particularly well suited for the fluidization of solids difficult to fluidize, wherein the solids are introduced to either an upper or lower fluidized zone while continuously subjecting both the upper and lower fluidized zones to mechanical agitation. The solids flow from the upper fluidized zone downwardly against the fluidizing gas through a plurality of tubular fluidized zones positioned intermediate to the upper and lower fluidized zones wherein the fluidized solids are subjected to heat transfer. The solids flowing from the intermediate tubular zones pass to the lower agitated zone. The process of the invention can be used for a variety of fluidization operations, including physical processes such as drying and chemical processes, and particularly fluidization processes for drying and/or chemically modifying starches.
