Summary

There is a focus on increasing energy efficiency in the fish processing industry in Norway. Refrigeration, and particularly freezing, is energy demanding and often not optimized with regard to energy usage. To evaluate different energy saving measures, a dynamic simulation model of a batch freezing tunnel for pelagic fish has been developed. To validate the simulation model, temperatures of air and product during a freezing process at an industrial plant have been measured. The results are compared and the model seams able to predict the temperature development with reasonable accuracy. The various uncontrollable variables of the product packages (e.g. air pockets) have significant effect on the results and are difficult to account for in a simulation model. However, the calibrated model is well suited for investigation of several energy saving measures.
