How Do Dry Ice Packs Preserve Seafood During Shipping?

Dry ice packs are the ideal solution for maintaining sub-zero temperatures during seafood transport, preventing thawing and preserving product quality. La glace sèche sublime directement du solide au gaz à -78,5 ° C (-109.3°F), providing an efficient cooling method without any water residue. This feature is particularly beneficial in preventing soggy or contaminated packaging, which is often a risk with traditional ice.

Fruit de mer, being highly perishable, is extremely sensitive to temperature fluctuations. When exposed to temperatures higher than freezing, seafood can deteriorate rapidly, affecting texture, goût, et la sécurité. Dry ice ensures that seafood remains in a frozen state for an extended period, maintaining its optimal freshness until it reaches the destination.

Key Benefits of Dry Ice for Seafood Shipping

• Durée de refroidissement plus longue: Dry ice keeps seafood frozen for up to 72 heures, depending on the package size and insulation used.

• Pas de résidu d'eau: Contrairement à la glace traditionnelle, la neige carbonique se sublime en gaz, ensuring no water buildup that could spoil the seafood.

• Superior Cold Temperatures: À -78,5 ° C (-109.3°F), dry ice offers much colder temperatures compared to regular ice (0°C or 32°F), making it ideal for frozen seafood.

What is the Recommended Amount of Dry Ice for Seafood Shipments?

When shipping seafood, the right amount of dry ice ensures that the products remain frozen throughout the journey. The amount of dry ice you need depends on several factors:

• Durée de l'expédition: Longer shipments require more dry ice to maintain low temperatures.

• Température ambiante: If the shipping route involves high ambient temperatures, additional dry ice may be necessary.

• Package Size and Insulation: High-quality insulated containers reduce sublimation rates and preserve the cold temperature longer.

How Much Dry Ice to Use?

As a general rule, utiliser 5-10 pounds of dry ice per 24 hours of transit for every 15 quarts of cooler space. This can vary based on external factors like temperature and the quality of insulation. For longer shipments or hotter routes, it’s essential to adjust the amount of dry ice accordingly.

Dry Ice Sizing Calculator for Seafood Shipping:

Use the following formula to determine the amount of dry ice required:

Par exemple, expédition 20 lbs of seafood for 48 hours with an average insulation cooler (box efficiency = 1.2) would require:

Meilleures pratiques pour emballer les fruits de mer avec de la glace carbonique

Proper packing ensures that your seafood stays frozen while also protecting it from damage during transit. Here are the key best practices:

1. Utiliser des conteneurs isolés: Insulated containers help maintain the cold temperature for longer, especially when used with dry ice.

2. Separate Seafood and Dry Ice: To avoid freezer burn, keep seafood separate from direct contact with dry ice using moisture-resistant bags.

3. Layer Dry Ice Properly: Place dry ice at the top of the container, Alors que l'air froid coule. This method, known as the “cold dome,” ensures that the seafood stays at the right temperature.

4. Assurer une bonne ventilation: Depuis la glace sèche sublime dans le gaz, it’s essential that the container is vented to allow gas to escape, preventing dangerous pressure build-up.

Safety and Regulatory Considerations for Using Dry Ice

Since dry ice is classified as a hazardous material (Et 1845), shipping with dry ice requires compliance with several safety regulations:

• Étiquetage approprié: Mark packages with “Carbon Dioxide, Solid” and include the UN 1845 étiquette.

• Gestion des précautions: Always use gloves and goggles when handling dry ice to avoid frostbite.

• Ventilation: Ensure that the container is not airtight, as this can cause dangerous pressure accumulation.

2025 Trends in Seafood Shipping

The seafood shipping industry continues to evolve, avec sustainability and efficiency taking center stage in 2025. Emerging technologies and new shipping solutions are improving the way seafood is transported, with a focus on reducing environmental impact and enhancing cold chain visibility.

• Production de glace sèche durable: Biodegradable dry ice packs and carbon capture technologies are gaining traction to reduce emissions.

• Surveillance avancée de la température: Real-time tracking systems, including Bluetooth and BLE sensors, are helping businesses monitor temperature conditions throughout the shipping process.

• Solutions de refroidissement hybrides: Combining dry ice with phase change materials (PCM) or gel packs is becoming more common for temperature control over longer durations.

Questions fréquemment posées

Q: How long can dry ice keep seafood frozen?
UN: Dry ice can maintain frozen conditions for up to 72 heures, depending on factors like insulation, La quantité de glace sèche utilisée, and the shipment’s duration.

Q: Can dry ice be used for overnight seafood shipments?
UN: Oui, dry ice is ideal for overnight shipments as it provides rapid cooling and ensures that seafood remains at the correct temperature for quick deliveries.

Q: Is dry ice safe for live seafood?
UN: Non. Dry ice is too cold for live seafood, and can kill delicate items like lobsters or oysters. Gel packs or PCM should be used instead for live shipments.
