Abstract: A method and apparatus for removing guts of a fish body, the method includes: transferring a fish body A, with a head cut off and removed, by a transfer device and cutting open the abdomen thereof with an abdominal blade on the way of transfer; transferring the fish body to a gut removal member and causing membrane separation blades, provided at an upper end portion of the gut removal member, to enter in between a peritoneal membrane portion on both sides of the vertebra and a fish meat inner wall on a head cut-off section of the fish body; swinging the gut removal member downwardly with its lower end portion as fulcrum to tilt the membrane separation blades from the horizontal state and peel off the peritoneal membrane portions from the fish meat inner wall; and shaking off downwardly the guts adhered to the peritoneal membrane portions.

Abstract: A device for efficiently and accurately punching out and collecting in a continuous and automatic manner an eyeball section of a fish. The device comprises a head part supporting table and a body part supporting table which can be opened and closed. The head part supporting table has an eyeball section discharge hole and a head part gripping device arranged on both sides of the head part supporting table to position an eyeball section of the fish on the eyeball section discharge hole. The device further comprises an eyeball section punching out blade body arranged above the eyeball section discharge hole in a manner of being movable up and down. The eyeball section of the fish is punched out by the punching out blade body and the punched out eyeball is collected through a suction hose connected to and communicating with a lower face of the eyeball section discharge hole.

Abstract: To obtain a quality-meat-attached backbone part suitable as a material for minced fish the invention proposes cutting off a fin part and a kidney from a meat-attached backbone part obtained when filleting a fish into three pieces. The meat-attached backbone part is conveyed by a pair of upper and lower conveyor belts while being sandwiched and held between the belts. When the backbone part reaches a fin cutter arranged in a midstream of the conveyance, a belly part is pushed by a first pushing lever while a back part of the meat-attached backbone part is received and stopped by a receiving and stopping lever, and the back skin from a back fin to a tail fin is cut off by the fin cutter. Then, when the meat-attached backbone part reaches a kidney cutter, the belly part of the meat-attached backbone part is pushed by a second pushing lever to position the kidney-attached backbone section of the meat-attached backbone part at a cutting position by a kidney cutter.

Abstract: A method of effectively producing minced fish meat in a large quantity from fish bodies having hard meat comprising supplying a substantially fixed and large quantity of fish bodies having hard meat to a fish body cutting means for constantly cutting all the fish bodies into a plurality of cut pieces, feeding the cut pieces of the fish bodies to a washing means for removing impurities such as scales, dirts, blood and internal organs, etc. from said cut pieces, crushing said cut pieces by a crusher for softening the fish meat, and then collecting the fish meat by a fish meat collecting means for obtaining the minced fish meat.

Abstract: An apparatus for collecting fish eggs comprises a conveyor for transporting fish with the upper half of each fish inclined obliquely upward, a pair of upper and lower conveyor belts for holding the tail of each fish therebetween during transport, a pair of upper and lower conveyor belts for holding the trunk lower half portion of each fish therebetween during transport, trunk support portions and fish back restraining frames arranged alternately on the lower trunk holding belt, a head cutter disposed close to the terminal end of the conveyor, a member for pressing the abdomen of each fish after its head has been cut off, and an operating mechanism for the pressing member. During transport on the conveyor, the eggs in the abdominal cavity of each fish move toward the tail of the fish under gravity, and the head is thereafter cut off by the cutter.

Abstract: An apparatus for collecting the flesh of fish comprising an endless belt for conveying a material and two rotatable hollow rolls for collecting the flesh of fish each having a multiplicity of flesh collecting holes in its peripheral wall and being closed at its one end and open at the other end thereof, the two collecting rolls being spaced apart by a distance in the direction of movement of the endless belt and held in pressing contact with the surface of the belt by separate contact pressure adjusting means individually, a scraping knife being disposed at the rear side of each collecting roll and adapted for sliding contact with the peripheral surface of the collecting roll.
