Abstract

A powder filling apparatus for filling a container with powder is provided. In the powder filling apparatus, a bottle is carried into a plurality of work units moving around successively. While the work units move to work stations disposed in a circumferential direction successively, the bottle is filled with powder by equally evacuating the inside and the outside of the container and dropping powder into the container simultaneously with raising the pressure outside the container. The bottle filled with powder is then taken out from the work units successively while the work units move around.
