How does the cooling compare?
Refrigerated Seawater (RSW) is a common method of chilling fish onboard fishing vessels. For pelagic fish that is caught in large quantities in a short period of time, RSW provides better turbulence and more uniform cooling compared to flake ice. The question is however, is there a better way? DeepChill® provides similar operational advantages to RSW such as ease of pumping and distribution; simply put, DeepChill® flows like water! The distinction however, comes from the cooling power. A study by Slurry Ice Centre in the Danish Technological Institute shows that cooling rate of DeepChill® Slurry Ice is 3-7 times higher than that of [single phase] chilled brine. As shown in the diagram, with increase of ice concentration, the Heat Transfer Coefficient and therefore the Rate of cooling increase.
Rate of Heat Transfer = Heat Transfer Coefficient x Surface area x Temperature difference
