Freezing and refrigerating seafood such as lobster, crab, and shark fin can be done using dry ice. Dry ice does not melt into water, making it a cleaner and more hygienic option than regular ice for refrigeration and freezing. It is widely used in countries such as Europe, America, and Japan. Additionally, dry ice can be used to accelerate the freezing process for fish, ensuring freshness and extending the time for preservation, up to ten times longer than regular ice.

However, storing and transporting dry ice requires a dry ice box, which is designed to keep the dry ice frozen and safe. Dry ice is solid carbon dioxide with an extremely low temperature of around -78°C, and direct contact with skin can cause frostbite. A dry ice box is made of durable, insulated materials that are able to maintain the low temperature required to keep the dry ice frozen.

Whether you are shipping seafood or looking to preserve it for an extended period, a dry ice box is a necessary tool for storing and transporting dry ice. It is a safe and effective way to keep seafood fresh and hygienic while ensuring its quality during transport.
