To provide a fluidized-bed dryer and a fluidized-bed drying facility enabling adhesion prevention etc. by a simple configuration when an object to be dried is supplied.
When brown coal 101 which is the object to be dried supplied to the fluidized-bed dryer 102 is supplied, dry brown coal 108 is supplied by an introduction line L5 for introducing part of the dry brown coal 108 dried within a drying chamber to a supply hopper 120, effects for suppressing adhesion of powder materials and agglomeration in a powder material supply system and an inlet of the fluidized-bed dryer 102 can be exhibited, so as to improve device operating rate of the fluidized-bed dryer 102. Moreover, a purge facility provided in a conventional supply line can be reduced, so as to enable simplification of the supply system and drastic reduction in purge operational cost.
