This integrated packaging system combines an 820 rear collar-type packaging machine, a dual-head weighing granule dispenser, and a square hopper elevator for fully automated, high-volume packaging of granular and irregular solid products. It is widely used in the food, snack, and agricultural industries for large-batch production of items such as nuts, dried fruits, coffee beans, grains, seeds, and pet food. The square hopper elevator ensures continuous and stable material feeding from the ground level to the weighing station. The dual-head weighing unit provides high-speed, accurate dosing for each package. The 820 rear collar-type forming mechanism produces large, well-defined bags with consistent sealing, ideal for retail and bulk packaging applications. This system is an ideal turnkey solution for large-scale production lines where capacity, efficiency, and packaging consistency are critical.
