1. Do not store frozen food in the refrigerator.
2. Do not put the packaged or unpacked quick-frozen food directly into the freezer. A plastic bag must be added to the package and the bag mouth should be fastened to avoid drying of the product or oxidation of the oil.
3. Do not freeze the thawed food again, because the quality of the food will not be as good as before.
4. Do not overfill the freezer, which will affect the indoor air-conditioning convection.
5. Do not store frozen food for too long.
