Family-owned J M Langaas has installed SuperFreeze plate and tunnel freezers for use with white fish. Utilising CO2 as the refrigerant, these reach temperatures of ‑44°C compared with ‑32°C for the company’s previous equipment.
Based in Lofoten, this fish buyer reports that quick freezing improves product quality and keeps it almost as good as when the catch is frozen at sea.
The plant has a capacity of 70 tonnes per day in full operation, freezing time is almost halved and electricity costs have been cut by almost 30 per cent. Waste heat is recovered for such applications as heating floors.
