Abstract
A method for processing fish can include transporting fully intact fish to a floating vessel, at least one of weighing and sorting the fully intact fish, forming a layer of frozen slime on an outer surface of skin of the fully intact fish, and freezing the fully intact fish by moving the fully intact fish through an ultra-low air temperature region. Related systems and apparatuses are also provided.
Claims22
A method for processing fish, the method comprising:
- transporting fully intact fish to a floating vessel, the fully intact fish comprising round fish;
- at least one of weighing and sorting the fully intact fish;
- pre-freezing the fully intact fish at a first temperature range, the pre-freezing forming a layer of frozen slime on an outer surface of skin of the fully intact fish;
- and
- freezing the fully intact fish at a second temperature range by moving the fully intact fish through an ultra-low air temperature region.
2 more elements
A floating vessel, comprising:
- a preliminary sorting apparatus operable to receive fully intact fish that comprises round fish from a fishing vessel;
- and
- a fish processing region including:
- a pre-freeze region that is configured to have a pre-freeze air temperature which facilitates forming a layer of frozen slime on an outer surface of skin of the fully intact fish;
- and
- an ultra-low temperature region that receives the fully intact fish with the layer of frozen slime on the outer surface of skin of the fully intact fish, the ultra-low temperature region configured to freeze the fully intact fish.
3 more elements
A method for processing fish, the method comprising:
- transporting fully intact fish to a floating vessel;
- at least one of weighing and sorting the fully intact fish;
- forming a layer of frozen slime on an outer surface of skin of the fully intact fish;
- and
- freezing the fully intact fish by moving the fully intact fish through an ultra-low air temperature region, wherein freezing the fully intact fish includes moving the fully intact fish through a plurality of zones of an ultra-low temperature region.
