ABSTRACT:
A powder filling apparatus and a powder filling method which enable powder to be densely filled in a short period of time is to be provided. This is a powder filling apparatus having a pressure hopper wherein the pressure hopper has a discharger for discharging powder and a gas inlet positioned above at least the surface of a powder layer formed by the powder in the pressure hopper; the powder layer is so formed as to blockade the discharger in the pressure hopper; in the powder filling apparatus, the inside of the pressure hopper is pressurized by leading in gas through the gas inlet in a state in which the discharger is closed, and the powder layer so formed as to blockade the discharger is discharged by opening the discharger after the pressurization thereby to utilize that pressure to load the powder into the filling container.
