1. A system for reducing metal and product-in-seal contamination in a package of produce product, the system comprising:
a tube positioned substantially vertically, the tube having a top, bottom, inside, and outside; a partially-enclosed cavity for containing the produce product, the partially-enclosed cavity having a cavity opening positioned below the bottom of the tube; a flapper gate assembly, connected to the top of the tube, comprising a linkage assembly, a pivot assembly, and a flapper gate,
the linkage assembly having a bracket attached to the outside of the tube and a linkage arm connected to the bracket in a fixed position relative to the tube;the pivot assembly positioned outside the tube and attached to the linkage arm, the pivot assembly comprising an actuator, a piston rod, a pivot arm, and a hinge,
wherein the actuator is configured to drive the piston rod, and the piston rod is connected to the pivot arm, which rotates around the hinge when the piston rod is driven; andthe flapper gate positioned inside the tube and connected to the pivot arm via the hinge, wherein the flapper gate is configured to rotate around the hinge when the pivot arm is rotated to regulate product flow in the tube; and a sealing assembly configured to seal the partially-enclosed cavity to form a fully-enclosed package. |
