Method for the skinning of tuna and other species for the canning industry and device for its implementation

摘要

The method involves turning the fish (4) around its own axis while a cutting blade is longitudinally displaced along the body of the fish and contacts the latter in such a way that the blade follows a helicoidal trajectory in relation to the skin of the fish thereby making it possible to fully skin the fish. To this end, the device has a pair of clamps (7-7′) to fix the fish in vertical position and preferably with the head facing downward. The clamps are aided by a rotational actuator (10) delivering said movement to the fish while the blade (11) is permanently pressed on the fish by a spring (17) and is moved along the fish by a cylinder (16) or any other appropriate means. The arm (13) is rotated on a support (15) located at mid-height and can be displaced transversally by a cylinder (19) so that the blade can permanently work in an imaginary plane (21) perpendicular to the axis of the fish.
