The first point of food warehouse management is to ensure that there are no expired varieties, so it is best to change from FIFO management to expiration date management (that is, FIFO near expiration date). If there are few varieties, the production date and validity period of each variety are not much different. For example, the validity period of product A is one year, and other varieties are also one year, so the production date can also be used as a management element, otherwise validity period management must be used. As for the layout of the site, firstly, the existing warehouses are partitioned, and each reservoir area has billboards, which can also be printed folders on A4 paper, and all kinds of data entering and leaving the warehouse can be registered and written off; Second, stacking should be strict. It is best to use pallets to place different types and batches of goods. When warehousing, material cards should be used on each pallet. Third, if possible, we should manage the storage space. The name, specifications, production date and expiration date of the goods placed in the first few trays in Area A should be clear at a glance. This step needs to be input into the computer system for easy viewing and inventory.
