Tittel

Handling, processing and freezing of pelagic fish in Norway

Sammendrag

Pelagic fish is one of the most valuable food products due to its high content of marine fat and proteins. The Norwegian pelagic fish industry processes almost 900 000 tonnes of herring and mackerel annually. The main volume is packed in carton boxes and frozen on shelves in batch freezing tunnels. Most of the refrigeration systems in this industry use ammonia as refrigerant. It is challenging to ensure even freezing of the products and to achieve filling – freezing – emptying ("turn over") of tunnels in less than 24 hours. The tunnels and packing that is used today require tunnel temperatures below -30°C. Low compressor efficiency at part load, non-optimal use of fans and bad air flow distribution lead to low energy efficiency. A screening of existing tunnels and refrigeration systems to investigate the main challenges in operation and management has started, and will be the base for further improvement of freezing systems and equipment and refrigeration systems, compressors etc. and improved management. Results will be given and discussed in the paper.
