Bivalve processing device

Abstract

The present invention provides a bivalve processing device capable of easily achieving high performance. The bivalve shell processing device uses the forced opening mechanism (8) to open the unprocessed shellfish (2), then takes out the edible part for raw food from the other shell (2b) located on the lower side, and closes the shellfish (2) near the forced opening mechanism. A foreign matter removal mechanism (6) is provided on the upstream side of the shell conveying direction, and the foreign matter removal mechanism (6) removes foreign matter attached to the surface of one shell (2a), at least at the position where the upper adsorption pad (61) abuts.

Description

technical field [0001] The present invention relates to bivalve processing capable of efficiently extracting the edible portion of raw bivalve shellfish for raw food, such as the adductor muscle composed of scallops and columella, from shells in a raw state device. Background technique [0002] In general, in order to extract (separate) the edible part of raw bivalve shellfish from the shell in a raw state (separate), such as the adductor muscle composed of scallops and columella, a so-called scallop muscle is used. It is a thin knife-shaped tool used as a shellfish screwdriver, which is cut by hand at the joint between the adductor muscle and the shell that closes the two shells of the scallop. [0003] However, in the operation of manually cutting and separating the adductor muscle of the scallop from the shell, the efficiency is poor, and a lot of labor and time are required. At this time, the freshness of the scallops decreases. [0004] Therefore, in the past, in ord...

Problems solved by technology

[0008] For example, since the two shells of the unprocessed shellfish are adsorbed by a pair of suction pads, the heated one shell of the pair of suction pads is separated from the edible part by a pad drive unit driven by an air cylinder. One side of the shell is forcibly opened, so when foreign matter such as parasites adheres to the surface of the shell, a gap is generated between the adsorption pad and the shell, the adsorption force decreases, and the opening of the other side of the shell is hindered, that is, the opening accuracy deteriorates, and it may not be possible. Reliably open (open the mouth of raw shellfish) one side of the shell, and even if one side of the shell can be opened, it takes time to open one side of the shell, resulting in decreased productivity

[0009] In addition, with respect to the forced opening mechanism for forcibly opening one shell, the first separation unit that sucks and separates the non-edible portion other than the edible portion from the other shell after opening, and after separating the non-edible portion The driving source of each driving system of the second separation unit that separates the edible part from the shell of the other side uses a pair of reciprocating cylinders, and it is difficult to coincide with the start and / or end timing of the respective drives, especially because Time changes, so when the wear of the abutting portion of the piston and the head cover or the rod cover is different, the timing of the start and / or end of each drive of a plurality of pairs of reciprocating cylinders is different, and it is impossible to use multiple reciprocating cylinders. The adsorption timing of the raw shellfish of the adsorption pad is consistent

[0010] In addition, since the non-food portion separated from the raw shellfish by the first separation unit is transported to the room, it takes time to clean the room.
