How to preserve cooked food when traveling in summer?
1. Fresh cooked food during the trip can be stored in ice packs: there are many cold meat specialty stores online at present. When the courier delivers the goods to the customer, it uses a sandwich bag with thermal insulation performance, which contains 1~2 packs of refrigerant ice packs, so that the food will not go bad for 7 or 8 hours. And both the bag and the frozen bag can be reused. After the temperature of the frozen bag rises, it can be put into the freezer for several hours, and can be used repeatedly after being taken out.
2. Ice bag is a new type of freezing medium, which has no water pollution during thawing and can be reused. Its effective refrigeration capacity is 6 times that of the same volume of ice, and it can replace dry ice and ice.
Ice pack is a basic component made of high-molecular compound with large cooling capacity, non-toxic and tasteless, and its contents are crystal clear, non-corrosive, non-reflective and elastic. The main material is CMC. ? 3. A simpler method is to keep fresh with foam box, and the fresh-keeping effect can last about 12~ 16 hours.
