According to the temperature of the refrigerator, food cold storage can be divided into four categories: fresh storage, frozen, quick-frozen and low-temperature storage. Refrigerators with different functions use plastic pallets with different elements. By introducing the characteristics of cold storage, we can naturally find the elements that should be considered when selecting plastic pallets. Storage-type cold storage includes fresh-keeping storage, cold storage and low-temperature storage as well. The storage temperature of fresh-keeping warehouse and cold storage is generally not too low, mainly used for the storage and preservation of fresh meat, dairy products, fresh eggs, fruits and vegetables, but there are still a large number of bacteria that can breed and multiply at this temperature, such as Listeria . To avoid external bacterial infection.
When purchasing plastic pallets, you should choose pallets that are easy to clean. Grid plastic pallets are not easy to clean because of the large number of meshes and are easy to hold dirt. Usually flat plastic pallets are chosen for easier cleaning and disinfection. The quick-frozen storage temperature is generally below -30℃, and is mainly used for quick-freezing of quick-frozen meat, frozen dumplings, frozen vegetables and other foods. This requires rapid freezing of food in a limited time. Quick-frozen warehouses are characterized by the need for quick-frozen food, which requires that air conditioners can be quickly replaced around the goods. When purchasing plastic pallets, consider choosing a plastic pallet with a larger grid to facilitate the flow of goods from the air conditioner to any direction and quickly freeze the goods.
