Abstract
A material re-aerating and flow control device for use in a material pneumatic processing system includes a housing defining a re-aerating chamber and having an intake end. The housing includes a material intake opening through the intake end of the housing for receiving material into the chamber. The material re-aerating and flow control device also includes a short hollow conduit member for discharging material from the chamber. The hollow conduit member includes a first end located outside the housing, and a second end, having a discharge port formed therethrough, mounted through the housing into the chamber. The material re-aerating and flow control device further includes a pneumatic conduit for introducing pressurized air into the chamber. The pneumatic conduit includes a first end located outside the housing, and a second end, having a pressurized air release aperture formed therein, mounted through the housing into the chamber. The second end and the pressurized air release aperture are positioned within the chamber and relative to the discharge port to form and direct a curtain of pressurized air radially across the discharge port of the hollow conduit member for re-aerati…
