DUST CONTROLLED CONTAINER FILLING SYSTEM

摘要

A filling system for filling plastic bags and containers in an expedited and relatively dust-free manner. The filling system includes a coaxial tube having a supply passage for supplying a material and a return passage for drawing dust from the container during filling. The coaxial tube includes at least one aperture within the sidewall that extends into the return passage that forms a vacuum suction force against a wall of film surrounding the coaxial tube during filling of a container.
