ABSTRACT:
A sanitary fill tube assembly includes a pair of large diameter fill tubes connected to a spreader having a rotary valve system mounted therein. The rotary valve system is actuated by pairs of actuator arms guided through openings in a manifold connected to the fill tubes to precisely move the rotary valve between open and closed position. The rotary valve includes elongated openings therein which are closely matched with and connected to the same size and shape passageways and discharge openings in the spreader so as to more accurately control and meter material being fed into a pouch, and to maintain the overall assembly in a sanitary condition.
