Fish scaling machine

A fish scaling machine comprising upper and lower conveyor means mounted on a machine frame to convey fish bodies to be scaled while being held between said conveyor means and moved in a conveyance direction, water injection means to spray water onto scales of said fish bodes on said conveyor means, said water injection means having at least two rows of water injection nozzles spaced in said conveyance direction to spray water onto the same scale or scales of said fish body, in at least two stages in accordance with the conveyance of said fish bodies generally in said conveyance direction, said water injection means further including water pressure adjustment section to apply water onto said scales of said fish body at a substantially uniform pressure from each of said two rows of water injection nozzles in spite of variation in the surface profile of said fish body to be scaled.

A fish scaling machine comprising upper and lower conveyor means mounted on a machine frame to convey fish bodies to be scaled while being held between said conveyor means and moved in a conveyance direction, water injection means to spray water onto scales of fish bodies on said conveyor means, said water injection means having at least two rows of water injection nozzles spaced in said conveyance direction to continuously spray water onto the same scale or scales of the fish body in at least two stages in accordance with the conveyance of said fish bodies in generally said conveyance direction, said water injection means further including water pressure adjustment section to apply water onto said fish body at a uniform pressure from each of said rows of water injection nozzles in spite of variation in the surface profile of said fish body to be scaled and said water injection nozzles of said at least two rows of water injection nozzles being offset from each other in a cross or width direction relative to said conveyance direction.

A fish scaling machine including upper and lower conveyors mounted on a machine frame to convey fish bodies to be scaled while being held between said conveyors and moved in a conveyance direction, water injection means for spraying water onto scales of said fish bodies on said conveyors, said water injection means having a plurality of rows of water injection nozzles spaced in said conveyance direction to sequentially spray water onto the same scale or scales of said fish body in at least two stages as said fish bodies are moved by said conveyors, said water injection means further including water pressure adjustment means for contacting said scales of said fish body with water at a substantially uniform pressure from each of said two rows of water injection nozzles in spite of variation in the surface profile of said fish body to be scaled.
