To provide a fluidized bed apparatus in which the yield and productivity of a product are improved by preventing a product particle from being stuck to a particle contact part in a fluidized bed vessel when the product particle is melted/granulated and to provide a method for treating a granular substance.
A cooling gas A2 such as cold air is supplied through an air supply pipe 6 to the inside of a fluidized bed F of the (granulated) particle in the fluidized bed vessel 1 to lower the temperature of the (granulated) particle (the fluidized bed F) at a cooling step of cooling the melted/granulated particle. As a result, such a phenomenon can effectively be prevented that the particle is stuck to the particle contact part in the fluidized bed vessel 1 and solidified there at the cooling step.
