Why is dry ice ideal for cold chain logistics?
Combien de temps dure la glace sèche?
Glace sèche sublimate (turns from a solid to a gas) at a rate that depends on several factors. Typiquement, dry ice lasts for about 24 à 72 heures, but this can vary. Le temperature range, le amount of dry ice, le type of packaging, et le ventilation all influence how long it lasts.
Factors Affecting the Duration of Dry Ice
-
Type d'emballage: En utilisant emballage isolé tel que styrofoam ou glacières helps extend the life of dry ice. Proper insulation prevents rapid sublimation by reducing the exchange of heat with the external environment.
-
Quantité de glace sèche: Larger quantities of dry ice last longer. Pour les expéditions plus longues, ensure you have enough dry ice to maintain the required temperature.
-
Température environnementale: Le température ambiante plays a significant role. Hotter climates cause dry ice to sublimate faster, while cooler environments extend its life.
-
Ventilation: Dry ice sublimates faster if it’s placed in a confined space with poor ventilation. Proper ventilation ensures a steady but controlled release of gas, helping to manage the cooling time effectively.
How to Extend the Life of Dry Ice During Shipping?
If you’re aiming for a longer shipping duration, several strategies can help extend the life of your dry ice.
1. Use Thick Insulation
Insulated packaging is critical. Materials like polystyrène élargi (PSE) ou mousse de polyuréthane are excellent choices to prevent heat from reaching the dry ice. By minimizing the heat transfer, these materials help maintain the cold temperature longer.
2. Store Dry Ice in a Cooler Box
UN refroidisseur designed for dry ice can extend its lifespan. These boxes are typically equipped with extra insulation and pressure-release valves that allow the dry ice to sublimate slowly without accumulating dangerous pressure.
3. Consider Dry Ice Sheets or Pellets
En utilisant Fiches de glace sèche ou boulettes instead of block dry ice can be a more efficient option, depending on the application. Pellets sublimate plus rapidement, so they might be more appropriate for short shipments, while blocks are better for long-lasting cooling.
4. Minimize Opening of the Container
Every time the shipping container is opened, the dry ice is exposed to warmer air, causing it to sublimate faster. Limit access to the container until delivery is necessary to maintain the dry ice for as long as possible.
| Facteur | Impact sur la durée de la glace sèche | Meilleure pratique |
|---|---|---|
| Isolation | Helps slow sublimation | Use thicker insulation materials |
| Quantité de glace sèche | Plus de glace sèche signifie un refroidissement plus long | Calculate the required dry ice amount |
| Environmental Temp | Hotter temps speed up sublimation | Ship during cooler weather or use cooling aids |
| Ventilation | Affects sublimation rate | Ensure proper ventilation or vented packaging |
Applications of Dry Ice in Cold Chain Shipping
Dry ice is used in various industries for the transportation of temperature-sensitive products. Here are a few key areas:
1. Pharmaceutiques et biotechnologie
Dry ice is commonly used for shipping vaccins, échantillons biologiques, et médicaments that need to stay at specific low temperatures to remain effective. Its ability to maintain ultra-low temperatures ensures that these sensitive items arrive safely and effectively.
2. Industrie alimentaire
Dans l'industrie alimentaire, dry ice is often used to ship aliments surgelés, viande, fruit de mer, et produits laitiers. Dry ice is perfect for long-distance food shipping, as it ensures that products remain congelé throughout their journey.
3. Flowers and Plants
For shipping couper les fleurs et plantes, dry ice helps maintain a cool environment, preventing wilting and damage from heat. Its consistent cooling is essential to maintaining product quality upon arrival.
Safety Considerations When Using Dry Ice
While dry ice is effective for cooling, it must be handled carefully to avoid potential hazards.
-
Porter un équipement de protection: Utilisez toujours gants et lunettes when handling dry ice to prevent frostbite.
-
Assurer une bonne ventilation: Carbon dioxide gas is released as dry ice sublimates. Make sure the packaging allows for proper ventilation to prevent dangerous gas buildup.
-
Follow Shipping Regulations: Dry ice is classified as a hazardous material. Make sure to follow all shipping regulations and properly label packages containing dry ice.
Exemple du monde réel: A pharmaceutical company used dry ice to ship temperature-sensitive vaccines across borders. En utilisant insulated cooler boxes and calculating the right amount of dry ice, they successfully kept the vaccines within the required temperature range for 48 heures.
