Is composed of a pressing frame 28 and a pressing rod 29, and is loosely movably coupled to the swing pin 18 of the suction nozzle portion 15 which is moved up and down by the drive frame 23 through the slot 27 so as to be able to move up and down. The lower pressing plate 29 allows both sides of the lower shell to be curved on one side as shown by the phantom line in FIG. 3 so as not to damage the scallops and to be pressed by its own weight. The suction nozzle portion 15 is composed of a suction nozzle 17 and a bellows 16 for making a swingable structure, and a swing pin 18, and swings to the drive frame 23 through an appropriate gap to the left and right and back and forth as shown in FIG. It is structured so as to be swingably locked by a moving pin 18.

The pedestal 35 for sitting the lower shell is an elliptical ring-shaped concave pedestal 37 and a locking groove 33 for the concave pedestal 37.
It is composed of a locking metal fitting (not shown) that is set via.
As shown in FIG. 4, the concave pedestal 37 is made of an elliptic ring-shaped elastic member. Moreover, the inclined contact concave surface 34 similar to the surface shape of the lower shell is formed on the upper concave surface by utilizing the characteristic that the surface shape of the scallop is similar regardless of size. A plurality of slits 32 are provided around the ring-shaped opening to improve the cushioning property and prevent the small shell from falling off. In addition, pedestal 3
The setting direction of 5 is made to coincide with the arrow X direction shown in FIG. 4 and the arrow X direction which is the process proceeding direction shown in FIG.

The lower shell 10c is seated on the pedestal 35 and set at a predetermined position in a state where the actuator 25 of the vertical drive unit 21 is retracted by the entire stroke. The actuator 25 operates to cause the lower shell pressing portion 2
The pressing plate 29 of 6 presses both edges of the lower shell 10c. The pressing force at this time depends on the weight of the pressing portion. a: The actuator 25 further descends and the drive frame 23 also descends, and the swing pin 18 (provided on the suction nozzle 17) loosely fitted to the drive frame is the long groove of the pressing frame of the lower shell pressing portion 26. Stop at the lowest position of 27. b; Therefore, the suction nozzle 17 has a predetermined height (the scallop 11
Stop from the upper end to Z) and approach a position suitable for sucking the liver 12. The height is preferably 9 to 12 mm.
In addition, the slot 27 adjusts the clearance between the nozzle and the liver. c; The bellows 16 extends and the suction force of the suction blower is generated around the nozzle tip 17a. a; The liver is first suctioned by suction. b: In order to promote suction, fresh water is discharged from the projection water nozzle 19 for assisting suction for an appropriate time from the start of suction. Since the scallops are not heat-treated, they are not separated and sucked. a; When the liver 12 is sucked by the suction nozzle 17,
Following this, the string (mantle) 13 is sucked in a state of being attached to the liver. b; as the suction is performed, the suction nozzle 17 moves the swing pin 18
Swing in an arc around the center and suck all straps.
(The string has the property of peeling together with the thin skin that covers them when peeled from the liver.) When the string is completely sucked, the suction nozzle 17 stops swinging due to its own weight, and at the same time rises by the actuator 25. Return to home position.

In the above-described visceral separation suction, the tip position of the suction nozzle at the start of suction is always at a predetermined position of the lower shell (preferably, the center of the nozzle is located at the position of point O in FIG. 3). It is necessary to be located regardless of size. However, in the present invention, since the seating pedestal 35 has the above-described configuration, the lower shell is parallel to the pedestal base (horizontal).
