PROBLEM TO BE SOLVED: To provide an efficient fluid bed apparatus which can prevent the inhibition of heat transfer due to adhesion and deposition of materials to be calcined such as waste gypsum.SOLUTION: An apparatus body 1 in which materials to be processed are supplied includes: a dispersion plate 2 disposed at the inside bottom, to which a fluid gas for fluidizing the materials to be processed is ejected; and heat transfer means 3 disposed above the dispersion plate 2, for transferring heat to the materials. The heat transfer means 3 includes a plurality of heat transfer elements 5 disposed at intervals inside the apparatus body 1. Scraping means 7 for scraping the materials to be processed, which are adhered to the heat transfer element 5, is movably disposed between the heat transfer elements 5. |
