Even in such a configuration, it is possible to remove the viscera A4 by peeling off the peritoneal membrane portions A5 and A5 to which the viscera A4 is attached from the fish meat inner wall A7.
- the fish A from which the viscera A4 has been removed by the viscera removal device 4 is conveyed to a residual material removal device 5 such as mehn provided on the downstream side of the viscera removal device 4 while being held by the holding belts 2a and 2a of the transfer device 2. Is done.
- This residue removing device 5 includes first to third abdominal cavity cleaning rotary brushes 5a, 5b, 5c, and the fish body A is disposed on the first to third abdominal cavity cleaning rotary brushes 5a, 5b, 5c.
- the first rotating brush 5a has a pair of left and right brushes arranged side by side.
- the first rotating brush 5a is detected by a photoelectric sensor and moved up and down by the first rotating brush 5a.
- 9a is activated, and the first rotating brush 5a is moved upward to scrape the residue adhering to the fish inner wall A6 while pressing against both sides of the fish inner wall A7 on both sides of the spine A6 in the abdominal cavity A3 of the fish A After removing, move down to the original position.
- the vertical moving device 9b of the second rotating brush 5b is operated, and the second rotating brush 5b is moved upward to move the second rotating brush 5b upward.
- the residual material such as mehn attached to the lower part of the spine A6 that could not be scraped off by the one-turn brush 5a is scraped off while being pushed down, and then moved down to the original position.
- the vertical moving device 9c of the third rotating brush 5c is operated to move the third rotating brush 5c upward to
- the first and second rotating brushes 5a and 5b move down to the original position after scraping off the residue adhering to the inner wall of the narrow abdominal abdominal portion A3 near the anus that could not be scraped off.
- the fish A that has been cleaned in the abdominal cavity A3 by the viscera removing device 4 is sent out of the machine from the conveyance end of the conveyance device 2.
- a viscera removal device for fish that can smoothly and reliably perform viscera removal processing while successively transporting fish whose heads have been cut.
