Product Introduction:
Dry ice is the solid form of carbon dioxide, widely used in cold chain transportation for items requiring low-temperature environments, such as food, pharmaceuticals, and biological samples. Dry ice has an extremely low temperature (approximately -78.5℃) and leaves no residue as it sublimates. Its high cooling efficiency and non-polluting nature make it an ideal choice for cold chain transportation.
Usage Steps:
1. Preparing the Dry Ice:
- Wear protective gloves and safety goggles before handling dry ice to avoid frostbite from direct contact.
- Calculate the required amount of dry ice based on the number of items to be refrigerated and the duration of transportation. It is generally recommended to use 2-3 kilograms of dry ice per kilogram of goods.
2. Preparing the Transport Container:
- Choose a suitable insulated container, such as a VIP insulated box, EPS insulated box, or EPP insulated box, and ensure the container is clean both inside and out.
- Check the seal of the insulated container, but ensure there is some ventilation to prevent the buildup of carbon dioxide gas.
3. Loading the Dry Ice:
- Place dry ice blocks or pellets at the bottom of the insulated container, ensuring an even distribution.
- If the dry ice blocks are large, use a hammer or other tools to break them into smaller pieces to increase surface area and improve cooling efficiency.
4. Loading Refrigerated Items:
- Place the items that need to be refrigerated, such as food, pharmaceuticals, or biological samples, into the insulated container.
- Use separation layers or cushioning materials (such as foam or sponges) to keep the items from directly contacting the dry ice to prevent frostbite.
5. Sealing the Insulated Container:
- Close the lid of the insulated container and ensure it is properly sealed, but do not seal it completely. Leave a small ventilation opening to prevent pressure buildup inside the container.
6. Transport and Storage:
- Move the insulated container with the dry ice and refrigerated items onto the transport vehicle, avoiding exposure to sunlight or high temperatures.
- Minimize the frequency of opening the container during transport to maintain internal temperature stability.
- Upon arrival at the destination, promptly transfer the refrigerated items to an appropriate storage environment (such as a refrigerator or freezer).
Precautions:
- Dry ice will gradually sublimate into carbon dioxide gas during use, so ensure good ventilation to avoid carbon dioxide poisoning.
- Do not use large amounts of dry ice in enclosed spaces, especially in transport vehicles, and ensure adequate ventilation.
- After use, any remaining dry ice should be allowed to sublimate in a well-ventilated area, avoiding direct release into enclosed spaces.
