An old-fashioned wheaten food enterprise has been producing quick-frozen wheaten food such as dumplings, steamed buns and steamed bread for 20 years. The original production line equipment is aging, with problems such as insufficient production capacity, long quick-freezing time (40 minutes required), and short product shelf life. To meet the needs of market expansion, the enterprise chose Yongxing Factory to upgrade the production line.
Based on the existing workshop layout of the enterprise, Yongxing formulated a transformation plan of “retaining core equipment and upgrading key links”, replacing the original ordinary quick-freezing tunnel with a high-efficiency spiral quick-freezer, and adding automatic plate arranging and conveying equipment. The upgraded production line shortens the quick-freezing time to 12 minutes, improves the toughness of the skin of dumplings and other wheaten foods, and makes them not easy to break after cooking; at the same time, through precise temperature control, the product shelf life is extended from 6 months to 12 months. The production capacity of the production line increased from 500kg/hour to 1200kg/hour, and energy consumption decreased by 20%. After the transformation, the enterprise successfully developed 3 new markets in northern China, with the highest daily sales exceeding 8 tons.
