Abstract
A heat treating apparatus for powder particles including a cylindrical treating chamber; a powder particle-supplying unit; a hot air-supplying unit that supplies hot air for heat-treating powder particles; a cold air-supplying unit that supplies cold air for cooling the heat-treated powder particles; a regulating unit for regulating a flow of the supplied powder particles; and a recovering unit that recovers the heat-treated powder particles. The regulating unit is a substantially circular columnar member, the hot air-supplying unit has an outlet opposite to the upper end portion of the columnar member, and the regulating unit is equipped with a substantially conic distributing member for distributing the supplied hot air in a circumferential direction and a rotating member for rotating the distributed hot air in a spiral manner, on the center of the upper end portion.
