1. Precautions for transporting frozen fish
1. Keep the temperature on hold
Frozen fish must be kept at-18°C or lower to prevent thawing and deterioration. Maintaining a stable low temperature throughout transport is crucial.
2. Packaging integrity
Proper packaging is key to protecting fish from temperature fluctuations, physical damage and contamination. The package shall be durable, leaky, and insulated.
3. Humidity control
Minimize the humidity in the package to prevent ice crystals and frozen cautery, which reduces the quality of the fish.
4. Transportation time
Plan transportation routes and duration to ensure that fish are always frozen before reaching their destination. Use an expedited transport method, if necessary.
2. Packaging steps
1. Prepare the materials
-Vacuum sealing pockets or moisture-proof packaging
-High-performance thermal insulation container (PSE, PPE, or VIP)
-Condensant (packs de glace en gel, glace carbonique, or phase change material)
-Hygroscopic pads and bubble pads
2. Pre-cooled fish
Make sure the fish is completely frozen before packaging. This helps to maintain a stable internal temperature during transport.
3. Vacuum seal or pack the fish
Fish fish using vacuum sealing pockets or moisture-proof packaging, which prevents air exposure and reduces the risk of freezing cautery.
4. Arrange the refrigerant
Place the pre-cooled fish in an insulated container. Spread the refrigerant (such as gel ice packs, glace carbonique, ou matériaux à changement de phase) evenly in the surroundings to ensure uniform temperature distribution.
5. Fix and seal the containers
Use a bubble cushion or foam to prevent movement during transport. Close tight tightly to prevent air exchange and temperature fluctuations.
6. Marquez l'emballage
Clearly marked packaging, labeled “perishable items” and “keep frozen”. Include handling instructions for transport personnel reference.
3. Temperature control method
1. Choose the appropriate thermal insulation material
Select the appropriate insulation containers according to the transportation time and external conditions:
-EPS container: lightweight and cost effective for short to medium duration transportation.
-EPP container: durable and reusable for long time transportation.
-VIP container: high performance thermal insulation, suitable for long time transportation and highly sensitive products.
2. Use the appropriate refrigerant medium
Choose a refrigerant suitable for the transportation needs:
-Gel ice pack: Suitable for short to medium length, non-toxic and reusable.
-Dry ice: Suitable for long time transportation, maintaining extremely low temperatures. Due to its extremely low temperature and sublimation properties require careful treatment.
-Phase change material (PCM): Provide accurate temperature control for multiple transportation times and can be reused.
3. Temperature monitoring
Use the temperature monitoring equipment to track the temperature throughout the transportation process. These devices can alert temperature deviations, allowing you to take immediate corrective action.
