An apparatus capable of directly producing a fine powder from a paste-like raw material is provided. A fine powder manufacturing apparatus 100 includes a grinding chamber 12 in which a rotor blade 20 configured and rotated with a blade 22 is housed with a gap between an inner wall surface and a temperature for generating hot air. A wind generator 31 and an outlet 30a are arranged to face the rotor blade 20 of the crushing chamber 12, and an introduction guide 30 for sending the warm air generated in the hot air generator 31 into the crushing chamber 12 and an outlet 40a Inside the introduction guide 30, it is arranged toward the rotor blade 20 of the crushing chamber 12, and is connected to the raw material supply pipe 40 into which the slurry-like raw material is continuously fed and in the middle of the raw material supply pipe 40, and is intermittently compressed. A compressed gas injection pipe 44 through which gas is injected, and the raw material blown off by the compressed gas is intermittently placed in the pulverization chamber 12 via the introduction guide 30 while being dried by drying with hot air. It fed into the chamber 12, to produce a fine powder with finely pulverized by grinding chamber 12. [Selection] Figure 1【課題】ペースト状の原料から微粉末を直接的に製造することが可能な装置を提供する。【解決手段】微粉末製造装置１００は、ブレード２２を有して構成され回転するローターブレード２０を、内壁面との間に隙間を有して収納した粉砕室１２と、温風を発生させる温風発生装置３１と、出口３０ａが粉砕室１２のローターブレード２０と対向して配置され、温風発生装置３１で発生した温風を、粉砕室１２の内部に送り込む導入ガイド３０と、出口４０ａが導入ガイド３０の内部にて粉砕室１２のローターブレード２０に向って配置され、スラリー状の原料が連続的に送り込まれる原料供給管４０と、原料供給管４０の途中に接続され、断続的に圧縮気体が噴射される圧縮気体噴射管４４とを備え、圧縮気体によって吹き飛ばされた原料を、導入ガイド３０を介して粉砕室１２の内部に断続的に温風に乗せて乾燥させながら粉砕室１２に送り込み、粉砕室１２にて微粉砕して微粉末を製造する。【選択図】図１
