Temperature maintenance

 

The figure below shows how temperature is maintained in the raw material using different ice types.

Even though the temperature of the crushed plate ice is higher than the temperature of the liquid ice, it is better maintained throughout the storage period. The reason is probably a larger area of contact for the liquid ice both with the walls of the tub and the fish.

This result supports the recommendation to initially cool the raw material with liquid ice, re-ice with crushed plate ice no later than after 24 hours, and then maintain the temperature after that with the crushed plate ice.
