Raw crabs are stored in cold storage:
1, hairy crabs can't be put in the refrigerator directly. Before putting it in the refrigerator, soak it in cold water to let the crabs absorb enough water, then put it in a container, cover it with a wet cloth (it is advisable that the wet cloth does not drip), take it out and soak it for about half an hour the next day, and then put it in the refrigerator for 7 days. This method is no problem.
2. Put a bottle of frozen mineral water in a packaging bag or box, then put the hairy crabs on it, cover it and put it in the freezer (remember that the freezer is not a freezer).
3, oxygen preservation
Put the hairy crabs into a deep bucket, then put them into clean water, then turn on the oxygen-increasing equipment and fill the water with oxygen to ensure that the hairy crabs can absorb enough oxygen and prevent them from dying from lack of oxygen. However, during the storage period, it should be checked every day, and the hairy crabs with insufficient vitality should be taken out and eaten in time.

Boil the crabs first, cool them, put them in fresh-keeping bags and seal them, and then put them in the refrigerator. You can also put crabs directly in the refrigerator and cover them with wet towels.
