Abstract
A fluid bed dryer comprises a bed plate having gas distributing openings in the plate. The gas distributing openings are arranged in pairs of substantially oppositely directed openings, and a depressed portion of the plate extends between the openings of each pair. Throughfall of products through such openings is substantially eliminated, and by suitably choosing the relationship of the effective area of the oppositely directed openings in the pairs of openings it is possible to obtain a desired relationship between the vertical fluidizing component and the horizontal transporting component of the upwardly directed gas flow through the openings of the bridge plate.
