Applications

Tunnel freezers for poultry, meat, fishing and salmon farming.

We use these tunnels to freeze finished or semi-finished product at the end of the line, before packing or cold storage.

  • Poultry

    Raw or cooked chicken pieces, fillets and products, in spiral or impingement tunnels.

  • Meat

    Burgers, portioned cuts and boxed meat, from the forming machine to packing.

  • Fishing

    Fillets, portions, shrimp and shellfish, with low product dehydration.

  • Salmon farming

    Salmon fillets and portions frozen continuously, and blocks in plate freezers.
