PROBLEM TO BE SOLVED: To shorten a heating time for obtaining a heat-processed product by efficiently conducting a heating process on a raw material. SOLUTION: This heat processing device includes a rotary furnace 10 to which material is supplied, and a heating means to indirectly heat material in the rotary furnace 10 by heating it, so that material supplied from one end side of the rotary furnace 10 is indirectly heated while agitated and carried to be discharged from the other end side. The rotary furnace 10 is composed of a non-circular cylindrical body. As the rotary furnace 10, an oval or sector-shaped cylindrical body may be used. COPYRIGHT: (C)2005,JPO&NCIPI
