The method comprises the following steps: raw material code scanning and warehousing: inputting raw material information into a production management system by scanning a material code on a raw material package, and generating a corresponding raw material warehousing record; code scanning and material sending: sending the information of the required raw materials to a corresponding production line by scanning the material codes on the raw material packages, and generating a material sending record; code scanning and feeding: scanning a material code on a raw material package to confirm the use condition of the raw material, and generating a feeding record; finished product code scanning and warehousing: inputting finished product information into a production management system by scanning a product code on a finished product package, and generating a finished product warehousing record; and code scanning and shipment: by scanning the product code on the finished product package, confirming sales information, and generating a shipment record. The method has the beneficial effects that the manual recording time and occasional errors are reduced, and the timeliness and accuracy of information tracing are improved.
