Freezer ice packs are an important tool for keeping food, medicine and other sensitive items stored and transported at a suitable low temperature. Proper use of frozen ice packs can significantly improve efficiency and safety. The following is the detailed usage:
Prepare ice pack
1. Choose the right ice pack: Choose the right ice pack based on the size and type of items you need to freeze. There are various types of ice bags, some are specially designed for medical transportation, while others are more suitable for daily food preservation.
2. Freeze the ice packs completely: Place the ice packs in the freezer for at least 24 hours before use to make sure they are completely frozen. For larger or thicker ice packs, it may take longer to ensure that the core is also completely frozen.
Use ice pack
1. Pre-cooling container: If you use an insulated box or refrigerated bag, place it in the freezer to cool in advance, or put several frozen ice packs in it for pre-cooling to improve refrigeration efficiency.
2. Pack items for freezing: Make sure items are frozen before placing them in an insulated container. This helps maintain low temperatures inside the container.
3. Place the ice packs appropriately: Distribute the ice packs evenly on the bottom, top and sides of the insulated container. Make sure ice packs cover key areas to prevent uneven temperatures.
4. Close the container: Make sure the container is well sealed to minimize air exchange and maintain internal temperature.
Precautions during use
1. Check the ice bag regularly: Check whether the ice bag is intact during use. Any cracks or leaks may affect the cooling effect and may cause hygiene problems.
2. Avoid direct contact of ice bags with food: To prevent potential chemical contamination, use food-grade packaging materials to separate food from ice bags.
Cleaning and storing ice packs
1. Clean the ice bag: After use, clean the surface of the ice bag with warm water and mild detergent, then rinse with clean water and dry in a cool place.
2. Correct storage: Make sure the ice bag is completely dry before putting it back into the freezer. Avoid heavy pressing or folding to prevent the ice bag from breaking.
Following these steps when using freezer ice packs will ensure your food, medicine, or other sensitive items stay appropriately cold during transportation or storage, keeping them fresh longer and reducing food waste. Proper use and maintenance can also extend the life of the ice pack.
