BACKGROUND OF THE INVENTION
The present invention relates to a frozen fish cutting device, and more particularly to a frozen fish cutting device for cutting and removing the skin of frozen fish such as skipjack.
[0002]
[Prior art]
For example, bonito is frozen in a round shape, and after landing, it is cut into vertical fillets or loins at the processing plant, except for the head, internal organs, tail, fins, etc. And the skin and blood clot of the frozen fish body made into loin etc. are removed with a cutting device.
The frozen fish body cutting apparatus has a support base, and the main body is supported on the support base. The main body is provided with a rotary blade housing portion having openings on the front and bottom surfaces, and the rotary blade housing portion is provided with a rotary blade fixed to the rotating shaft of the motor. The rotary blade is constituted by a substantially drum-shaped holding portion and a blade portion, and the blade portion is fitted and fixed in eight holding grooves formed on the outer periphery of the holding portion.
[0003]
The rotating blade rotates together with the rotating shaft of the motor, and the frozen fish body held with both hands is applied to the blade portion of the rotating rotating blade, and the skin or the like is cut and removed. The rotary blade of the rotary blade container is about 2500 revolutions per minute at the peripheral speed. The cutting rod falls downward and is carried out on a conveyor installed opposite to the opening of the bottom plate.
