Abstract
A filling head for a pouch packaging machine or the like has a plurality of rotating chambers for receiving measured amounts of an aerateable powder. Pistons aligned with the chambers can be inserted into the chambers to compress the powder and remove entrained air. The pistons are made of porous metal and communicate with a vacuum source for removing air from the chambers. The chambers can be opened after the compression stage to dispense the compacted pellet of product to an open pouch below.
