Further, after the potatoes are weighed and selected by the belt conveyor in the step (1), the shapes and sizes of the potatoes are uniform, and the residual impurities and mud cakes in the raw materials are less.
Further, in the step (2), the potatoes are washed in a drum washing machine for 25 min.
Further, when the steam peeling machine peels in the step (3), steam can uniformly act on the whole surface of the potatoes, so that the peel layer with the thickness of 0.5-1 mm can be removed, and the whole potato pulp of the potatoes can be leaked.
Further, the browning inhibitor added in the step (3) during peeling the potatoes is sulfite, and the potatoes are washed for 5 times by using clean water.
Further, the thickness of the potato sliced by the slicer in the step (4) is l0 mm.
Further, when the potato chips are soaked in the material cylinder and then taken out in the step (4), the clear water on the upper layer of the material cylinder is filtered, and the starch deposited at the bottom of the material cylinder is collected and stored.
Further, in the step (5), the potato chips are soaked in the sulfite test solution for 10min, and the soaked potato chips are washed in clear water for 5 min.
Further, in the step (6), the potato chips with surface moisture drained in the step (5) are put into a packaging bag in a group of 5-7 chips for vacuum packaging.
