Abstract
An apparatus which can clean powdered material from a filled pouch during a filling operation and at the same time introduce an inert atmosphere into the pouch prior to sealing. The apparatus includes a pair of wheel members mounted on a shaft for opposite rotation, the wheels having apertures which will eject inert gas in an opposing direction. The wheel members serve the dual function of blowing powdered material from the top of the filled pouch while at the same time introducing an inert atmosphere therein. The wheel assembly is especially suited for a high speed filling operation such as that commonly found in conjunction with a multiple stationed and rotatable filling apparatus.
