In collaboration with The Fisheries and Marine Institute of Memorial University of Newfoundland, Sunwell has conducted research to study the effects of DeepChilling on seafood in comparison with other cooling and preservation methods. This report reviews results from a few research studies and presents the implications for the shrimp industry.
DeepChill® vs. RSW
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.

Ice Slurry: Applications
The role of secondary refrigerants is expected to grow as the focus on the reduction of greenhouse gas emissions increases. The effectiveness of secondary refrigerants can be improved when phase changing media are introduced in place of single-phase media. Operating at temperatures below the freezing point of water, ice slurry facilitates several efficiency improvements such as reductions in pumping energy consumption as well as lowering the required temperature difference in heat exchangers due to the beneficial thermo-physical properties of ice slurry.
Ice Slurry: Advanced Fish Chilling and Preservation Technology
The rapid increase of the world population in the past few decades has put added pressure on the fishing and aquaculture industries to improve the production, quality, and shelf life of fish. One focus is to implement advanced means of fish preservation for all after-catch operations.
