Do you really understand the coding of the production date?

The production batch number is in industrial production. Although the raw materials and processes are the same, the quality and performance of the products produced by each batch of materials are still different. To

the responsibility of tracking this batch of products after the fact to avoid confusion, so each batch of products has a corresponding batch number. It is a set of numbers or letters plus numbers used to identify 'batch'

words. It is generally composed of two digits of the year, month, and day of the production time.

, and corresponding content can be added with the advancement of the production process, and at the same time a corresponding

Production records. According to the production batch number and corresponding production records, the source of the raw materials of the batch of products and the history of the drug formation process can be traced; after the drug is formed into a finished product, the drug can be traced based on the sales record. The market destination of the drug; the quality of the drug after it enters the market; the batch of drugs can be controlled or recycled when needed. For drug supervisors
