Fish Defroster


PERUZA professional fish defroster is designed for the quick defrosting of Anchovies, Sardines and other types of pelagic fishes. The defroster handles fish in blocks but can also work with IQF products. It takes only 45 minutes to defrost a block of frozen fishes in the PERUZA defroster and the defrosting line ensures non-stop defrosting work – up to 1200/2400 kg/h (single/double version).

Each defrosting line needs only one operator for placing the fish blocks into the defroster bath. The blocks are placed in all bath areas and are defrosted with the help of warm water and airflow. The programmable logic controller automatically regulates water temperature and level for the most efficient defrosting. Afterward defrosted fish falls onto the conveyor belt and is transported to the next technological unit. There is no damage to the product and thus less giveaway during this stage of processing.

The professional fish defroster ensures faster defrosting and continuous process for more efficient fish processing. Reduced labor costs are also a significant benefit.
