To provide a heat treatment furnace suitably used in manufacturing, in particular, foamed ceramic particles, by continuously performing batch treatment while utilizing the advantages of batch type heat treatment of a constant residence time, charging/recovering a particulate material as it is, and performing the heat treatment such as burning while keeping the advantages of the batch treatment, in a method of performing heat treatment on the particulate material by a medium fluidized bed.
The particulate material is introduced to the medium fluidized bed in a reaction chamber, properly fluidized by the airflow applied within a range not scattering and not fusing/flocculating the treated particulate 6, and treated by heat while residing in the reaction chamber for a specific time. Then the heat treated particles are discharged to the outside of the medium fluidized bed in accompany with the airflow while increasing the airflow, and separated from the airflow by a separator 4 installed at a latter part of the fluidized bed to be recovered.
