摘要： An apparatus for continuously supplying fine particles (powder) in minute and quantitative amounts in a dispersed manner, is disclosed. An orifice throat 5 is formed in an orifice tube, and a powder carrying tube 7 is connected to the orifice throat. A powder suction tube 9 having a shape of an inverted funnel extends to the powder carrying tube, and a plurality of holes 16 are formed on a tapered circumferential surface of the powder suction tube 9. A powder storing container 10 closely contactedly receives the powder suction tube 9 in an air-tight state, but allows the powder suction tube to perform straight movements. A carrying system raises the powder storing container at a constant velocity, and a compressed gas injecting channel is connected to an upper portion of the powder storing container. A gas spouting nozzle 4 is connected to a compressed gas source, for spouting a compressed gas into the orifice throat 5 so as to form the powder into an aerosol. The fluidizing of the powder can be adjusted by adjusting the flow rate of the compressed gas (flowing through said compressed gas injecting channel 8), and the fluidizing of the powder is maintained at a constant level by raising the powder storing container at a constant velocity, so as to supply the powder quantitatively and continuously in a dispersed manner by forming an aerosol.
