Zusammenfassung:PROBLEM TO BE SOLVED: To enable adjustment of the compression degree of a granular powder raw material in the top of a screw in feeding of the raw material comprising conveying along a screw shaft direction by rotation-driving the screw disposed in a barrel.SOLUTION: A device for feeding a granular powder raw material comprises: a barrel having the introduction and discharge ports of the granular powder raw material; a screw; a screw rotation-driving unit conveying the raw material in a screw shaft direction by rotation-driving the screw; plural discharge blades disposed facing the top of the screw in the vicinity of the barrel discharge ports; and a blade rotation-driving unit rotation-driving plural discharge blades in a revolution different from that of the screw rotation-driven by the screw rotation-driving unit. A raw material filling space which adjoins the discharge port of the barrel and in which the flight scraper of the screw does not exist is provided in the internal space of the barrel.SELECTED DRAWING: Figure 1 【課題】バレル内に配置されたスクリュを回転駆動することで、スクリュの軸方向に沿って粉粒体原料を搬送して供給する粉粒体原料の供給において、スクリュの先端部における粉粒体原料の圧縮の度合いを調整可能とする。【解決手段】、粉粒体原料の供給装置において、粉粒体原料の導入口と排出口とを有するバレルと、スクリュと、スクリュを回転駆動することで、スクリュの軸方向に粉粒体原料を搬送するスクリュ回転駆動装置と、バレルの排出口付近において、スクリュの先端部に対向して配置された複数の排出羽根と、スクリュ回転駆動装置により回転駆動されるスクリュの回転数とは異なる回転数にて、複数の排出羽根を回転駆動する羽根回転駆動装置と、を備え、バレルの内部空間において、バレルの排出口に隣接するとともにスクリュのフライトが存在しない粉粒体原料充填用空間が設けられている。【選択図】図1
