Tunnel Freezer (IQF)

Our tunnel freezer is composed of two series-connected belts, which are spatially separated.
In the first stage, the products are cooled down from +15° C to about 5° C.
The evaporator of this stage operates at a vaporization temperature above +/- 0° C.
Thereby it must not be defrosted.

In the second stage of the tunnel freezer operates with an evaporation temperature of -40° C and freeze the product to -18° C. The main advantage over other vendors’ systems is the combination of two in-line systems, which guarantee a continuous production with low defrost cycles.
The biggest benefit for you as user of our IQF freezer is the fact that each litlle item, for example green pees, are individually (so per item) frozen, no lumps.

With our 20 years of experience as production & engineering company in the food machinery we know exactly what you need as a customer.

  • PLATE FREEZERS VERTICAL

    Vertical plate freezers are usually applied for freezing of large quantities of fish or meat. In general the coolant for the plates freezers is; Ammonia, CO2 or synthetic refrigerants.

    Unifreezing delivers vertical plate freezers that are developed to be cooled by natural refrigerants such as ammonia and CO2. With the use of CO2, a temperature of-50 degrees Celsius is possible inside the plates, achieving a significantly shorter freezing time of the product, consequentially increasing the capacity of the plates freezer (minimum 25%).

    The plate freezers can also be cooled with synthetic refrigerants such as R507 or R404A.

    PLATE FREEZERS HORIZONTAL

    These plate freezers can be supplied with or without insulated enclosure freezers and are mostly used for freezing of more expensive fish products such as fish fillets, shrimp and surimi but also for meat fillets as poultry.

    The products which are frozen in horizontal plates freezers are usually pre-packed in a carton or an aluminium tray before the product is put in the horizontal plate freezer.
