PROBLEM TO BE SOLVED: To provide a fluidized bed drier and fluidized bed drying equipment capable of promoting fluidization by performing proper mixing in the fluidized bed drier.SOLUTION: In this fluidized bed drier for drying a powder and granular material of high moisture content, adhesive property and condensing property, such as brown coal, a tilted section 130 of an angle of repose of powder and granular material or more and 90° or less is disposed on an inlet section 102a of the fluidized bed drier 102A, and the brown coal 101 is supplied from an upper section of the tilted section 130 or along the tilted section 130. Thus the brown coal is moved to a bottom side of a fluidized bed 111 along the tilted section 130 while mixed with the dried powder and granular material around, and further fluidized while mixed with the dried powder and granular material around again by fluidizing steam 107a, 107b supplied from a dispersion plate 116 at the bottom side, to start its drying. |
