Trial 2 – Monitoring of fish temperatures, stored in liquid ice, with bins filled to various capacity.

A small trial was set up to see how quickly the fish stored in liquid-ice dropped in temperature, as the bin was being filled to capacity. Normal practice in the fishroom included a thick layer of flake ice at the bottom of each bin. After 2/3 baskets of fish (approx 90kg) were packed into the bin a layer of liquid-ice was applied. Each layer was left standing for approximately 60 seconds, letting the liquid-ice solidify, before the same onboard practice was applied again.

The bin sampled was small gutted haddock. The ambient temperature was 9.0°C, as was the sea temperature. The temperature of the fishroom was -0.7°C.

The bin was ½ full when the trial started. After 35 minutes the bin was completely full, containing 456kg of fish.

The thermocouple was placed in the fillet of a fish, in the middle of the bin.
