The invention discloses a food packing system, which comprises a net weight scale, an inspection scale, a heat sealing machine, a bag reverser, a reshaping machine and an electric cabinet for controlling the previous parts, wherein the net weight scale consists of a suspended weighing sensor, a scale body and a weighing display; the upper end of the net weight scale is provided with a transition bin, and the lower end of the net weight scale is connected with the feeding hole of the inspection scale; the discharge hole of the inspection scale is connected with the feeding hole of the bag reverser through a heat sealing conveyor, and the heat sealing conveyor is provided with the heat sealing machine; and the discharge hole of the bag reverser is connected with the feeding hole of the reshaping machine. Because a suspended weighing mode is adopted in the food packing system, the error of each bag is less than 5 grams, the requirement for small bag weighing precision in production is met, and the adding times after reweighing is reduced and avoided; the food packing system is simple in structure and convenient to operate, reduces the labor intensity and improves the efficiency of a sound field; a dust removal device is arranged outside the scale body of the net weight scale, so that the production environment is cleaner; and a mirror finished stainless steel material is adopted in the scale body, so that propagation of bacteria is prevented.
