ABSTRACT:
The invention provides methods, systems and apparatus for the metered transport of fine powders into receptacles. According to one exemplary embodiment, an apparatus is provided which comprises a hopper having an opening. The hopper is adapted to receive a bed of fine powder. At least one chamber, which is moveable to allow the chamber to be placed in close proximity to the opening, is also provided. An element having a proximal end and a distal end is positioned within the hopper such that the distal end is near the opening. A vibrator motor is provided to vibrate the element when within the fine powder.
