Patent Summary

A device for removing fluids or solids from particulate materials comprises a container with an annular process chamber divided into inlet, intermediate, and outlet cells. It includes an introduction means, a discharge means, a ventilator supplying a first fluidizing agent (e.g., superheated steam) through an inflow bottom to create a fluidized bed, a heating means, swirl impellers, and a dedusting means. To enhance mixture transport and turbulence, the inflow bottom may feature uneven surfaces, first nozzles may supply a second fluidizing agent to the inlet cell parallel to the inflow bottom, and flow guidance members may be positioned above or below the inflow bottom. Crucially, the inflow bottom surface area in the inlet cell is larger, preferably twice as large, as in intermediate cells.
