Abstract: A method and an apparatus are capable of automatically performing an operation of mounting shellfishes to a pin inserted in a vertical rope. Insertion holes are formed in ears of two shellfishes in parallel. While each pin is cut out one by one from a series of pins formed of a large number of continuous pins, the cut-out pins are inserted through the vertical rope at substantially equal intervals. A pipe-shaped guide is inserted through the insertion hole of each of the two shellfishes, and an end portion of the guide inserted through the insertion hole is put on each end portion of the pin. The pin and the two guides are arranged in a straight line. The shellfishes are transferred and mounted onto the pin by sliding the two shellfishes along the respective guides beyond shellfish locking protrusions of the pin.

Abstract: In a shellfish processing method, meat is separated from shells by injecting liquid into inside of the shells of the shellfish, thereby opening the shell. After one of the shells is opened, associated parts of the shellfish are suckingly removed independently or collectively in part or in total. An opening portion is formed in a part of a shell of the shellfish and associated parts of the shellfish are suckingly removed through the opening portion independently or collectively in part or in total. After the associated parts are suckingly removed, the meat is separated from the other shell by injecting liquid in the shellfish. The opening portion is formed in a part of the shell by removing a part of the shell by a cutting operation or by perforating a part of the shell or by breaking a part of the shell by pressurization. Fragments and powder of the shell produced when the opening portion is formed in the shell is removed by suction or liquid washing.
