The nitrogen machine is a fully automatic weighing and packing machine specially used for packing bags of potato chips and French fries. As long as the staff pour the material into the material hopper, the potato chips and French fries are transported to the 10-head electronic combination scale through the material lifting for weighing and measuring, and then the potato chips are automatically weighed and packaged through a series of processes such as feeding, filling nitrogen and sealing. The difference between this machine and other automatic weighing and packaging machine of potato chips is that it is separately configured with a nitrogen machine, which can fill nitrogen into the packaging of potato chips at the same time, filling nitrogen can improve the quality period of potato chips, and filling bags of potato chips with nitrogen can effectively prevent potato chips from breaking during transportation. In general, the nitrogen machine equipment is purchased by customers themselves, or directly buy bottled nitrogen, the nature is the same, but with the machine supporting production, it will be more suitable.
