出端部より搬出される。 Then, when the hinge part of the cultured shellfish is placed first and both side edges of the cultured shellfish are fed, only the both side edges of the cultured shellfish are held by the belt conveyor,
The shells are transported one after another while maintaining or retaining this clamped state and the posture of the shellfish, and as each shellfish passes through the rotary grinding body in turn, each claw of each rotary grinding body hits the surface of the shellfish and scrapes off the deposits. During this time, each shellfish moves forward while being held between its both side edges, and the cultured shellfish from which the deposits have been scraped off is carried out from the carrying-out end of the conveyor.

を行える。C. Effects of the Invention The first method invention involves holding only both sides of a cultured shellfish, transporting the shellfish with the hinge part at the top while maintaining that position, and removing harmful deposits on the surface of the shellfish with the plurality of claws. The method allows cleaning of cultured shellfish by removing the shellfish by removing it, avoiding contact of a large number of claws with the fragile parts on both sides of the shellfish, sufficiently protecting the shellfish, eliminating the conventional hand-holding work.

がないから安全である。 In the second device invention, the first method invention can be carried out, and a conveyor 20 is provided which can grip only both sides of the shellfish A and convey it to the rotary grinding body 40. It is possible to securely hold the shellfish A, especially by pinching the fragile parts on both sides of the shellfish, to avoid contact with the rotating grinding body 40, to protect the shellfish A, and to avoid damaging the shellfish A, and to hold the shellfish A in the conventional manner. It is safe because there is no

順次到来するごとに同様の効果を奏する。 In the third device invention, each claw 43 moves toward the center in the radial direction while escaping in the circumferential direction due to the contact resistance with the shellfish A, so that each claw 43 moves along the surface of the shellfish A. Each claw 43 moves while being in contact with each other, which has the effect of scraping off deposits without damaging the shellfish. Further, when the shellfish A passes the position of the rotary grinding body 40 and the external force applied to the claws 43 is removed, each claw returns to its original position, and the same effect is produced each time the shellfishes arrive one after another.

3, the rotary grinding body 40 is prevented from moving in the axial direction, the position of the claw 43 is stable, it rotates at the desired location, there is no fear that the claw 43 will hit the conveyor 10 on both sides, and the position of the shell A is maintained. As mentioned above, since each pawl 43 has different phases and is sequentially shifted in the axial direction, the rotary grinding body 40 rotates once. Ba,
The claws 43 come into contact with the surface of the shellfish A almost without gaps, and have the effect of cleaning the entire area of the shellfish A.

By fixing it, the amount of strain given to the spring member 44 in advance can be changed and the repulsive force can be adjusted, and it is also possible to adjust the repulsion force, even when a group of shellfish with a large number of strongly attached objects such as the Fuji pot are attached. ,
A spring force commensurate with this can be obtained. This adjustment can also be made depending on the type of shellfish, resulting in a high yield.
