Abstract
The present invention includes a method for processing and trimming products such as fish fillets where the product is form frozen forming a thin frozen shell round the product and the subsequent processing of the product uses that condition to remove the fish skin and bones with more efficiency than any prior art methods whereas the quality of the product is increased due to less loss and less loss in liquid from the product than known by prior art methods.
Claims14
A method for processing fish or fish fillets by removing at least a part of the bone area simultaneously as the fillet is skinned, the method comprising:
- form freezing the fish to be processed by combining blow-and-touch-freezing, and
- removing the fish skin after the necessary form freezing is obtained,
- wherein the form freezing comprises cooling the surface of a conveyor belt by an airflow, the conveyor belt in a freezer comprising drop-shape aluminium beams, lowering the temperature of the aluminium by airflow, such that the heat from the fish fillet is removed through touch freezing, and wherein the airflow from above and sidewise freezes that part of the fillet, which does not touch the aluminium beam, so that frozen shell is generated around the fillet.
