ABSTRACT:
An apparatus for providing an air seal for a device discharging a compressible product, the apparatus including a generally horizontal conduit having an upwardly opening inlet and an outlet spaced from the inlet, a packer blade mounted in the conduit for pivotal movement about a generally vertical axis, the packer blade having a stroke path extending beneath the inlet, a motor connected to the packer blade to cause reciprocating pivotal movement of the packer blade about the axis so that product entering the conduit via the inlet is swept by the packer blade toward the outlet, and a discharge resistor which is located in the conduit between the packer blade and the outlet, which resists the flow of product through the conduit toward the outlet, and which permits compressed product to flow out of the conduit via the outlet, such that the packer blade and the discharge resistor cause uniform compression of the product between the packer blade and the discharge resistor so as to form a plug of product that substantially prevents air flow through the conduit in either direction.
