Product flows using gravity from the supply hopper bin to the product feed at the top of the machine. The product flows through a gravity gate into a funnel spout, and into a bag. No air or electricity is required for basic operation, and the GB Series includes a mechanical scale gross weight filler that simultaneously fills and weighs products in bags.

NOTE: Product testing may be required to determine actual bag filling rates and bag weight accuracy.
