摘要

The machine has a chassis (1) on which a frame (2) supporting a trough (5) is mounted. An open cut tank (4) for receiving a product to be dosed is mounted on a belt of the trough by a hinge and a support. A flexible and rigid piping (23) connects a nose (10) of the trough with dose separation valves (20, 21). The trough receives a multi-thread tappet screw (3) installed concentric with a rounded shape of a bottom of the trough. The screw comprises threads that are digressive towards an outlet of the screw.
