Abstract
Methods and systems for processing fish are provided which enable cutting of the fish and removal of the viscera without damage to either the viscera or the remaining fish product. The systems may include an adjustable cutting device to cut the belly in a particularly unobtrusive manner and/or an adjustable gutting device to severe a gullet of the fish from the fish body and to gather and remove the viscera without significant damage to the viscera or the remaining fish product. Extractors for severing the connection between the gullet and the fish are also provided to assist in removal of the viscera, including the gonads. Vacuum head assemblies for cleaning a cavity of the fish after the viscera is removed are also provided.
Claims12
A fish processing system, comprising:
- a blade to incise a belly of a fish when the fish is transported from an upstream location across the blade;
- a guide located downstream of the blade to guide the fish to a predetermined elevation for a gutting operation;
- and
- a gutting device positioned downstream of the guide, the gutting device including
- an extractor having a tip to enter a head end of the fish and sever a gullet from a collar of the fish during the gutting operation,
- an actuator operatively coupled to the extractor to actively move the extractor between an entry elevation in which the tip of the extractor is located below a backbone and above the gullet of the fish when the fish is at the predetermined elevation and an exit elevation in which the tip of the extractor is lower relative to the entry elevation, and
- a sensor positioned to sense a location of the fish during the gutting operation and communicatively coupled to the actuator to cause the actuator to actively move the extractor from the entry elevation to the exit elevation after the extractor moves, with the elevation of the extractor held constant at the entry elevation, a distance from first contact with the fish sufficient to cause the gullet to be severed from the collar of the fish.
A gutting device of a fish processing system, the gutting device comprising:
- an extractor having a tip to enter a head end of a fish during a gutting operation and sever a gullet from a collar of the fish;
- an actuator operatively coupled to the extractor to actively move the extractor between an entry elevation in which the tip of the extractor is located below a backbone and above the gullet of the fish as the fish approaches the extractor at a predetermined elevation and an exit elevation in which the tip of the extractor is lower relative to the entry elevation;
- and
- a sensor positioned to sense a location of the fish during the gutting operation and communicatively coupled to the actuator to cause the actuator to actively move the extractor from the entry elevation to the exit elevation prior to exiting the fish and after the extractor moves, with the elevation of the extractor held constant at the entry elevation, a distance from first contact with the fish sufficient to cause the gullet to be severed from the collar of the fish.
