PROBLEM TO BE SOLVED: To provide a fishery paste product raw material production device securely preventing the leakage of raw material in the case a cutter edge is rotated forward and reverse, performing production with a high yield, securing the cleanliness of the whole device, further, simple in the assembling/deassembling of a sleeve, and further easily and perfectly capable of performing cleaning.SOLUTION: Provided is a fishery paste product raw material production device comprising: a freely rotatable dish body 2 provided with an annular recessed part 2a storing frozen fish meat surimi raw material； the cutter edge 5 of a silent cutter arranged so as to be freely rotatable forward and backward at the inside of the annular recessed part； a cutter cover 10 covering at least the upper part of the cutter edge and further confronted with the outer circumferential flat upper face 2b rotating in the dish body via a fine gap with the circumferential inner face； and a sleeve 13 suppressing the leakage of the raw material in the dish body to the outside with the fine gap part interposed. The sleeve is integrally supported by the dead weight on both the sides in the periphery of the cutter cover freely movably up and down and not so as to be fallen in such a manner that it is slid with the outer circumferential flat upper face.SELECTED DRAWING: Figure 2【課題】カッター刃が正逆回転する場合に確実に原料の外部への漏出を防止し、歩留まりの良い製造を行い、装置全体の清潔性を確保し、しかもスリーブの分解組立も簡単で、清掃も簡単にかつ完全に行える水産練製品原料製造装置の提供。【解決手段】凍結魚肉すり身原料を収容する環状凹部２ａを備えた回転自在な皿体２と、環状凹部内で正逆回転自在に配設されたサイレントカッターのカッター刃５と、少なくともカッター刃の上部を覆うとともに周縁内面をもって皿体の回転する外周平坦上面２ｂと微小間隙を介して対面している刃物カバー１０と、微小間隙部分に介在されて皿体内の原料の外部への漏出を抑えるスリーブ１３と、を有しており、スリーブは、カッター刃の正逆回転時において、刃物カバーの周縁内面側に自重によって外周平坦上面に摺接する様に上下動自在にかつ落下しない様に一体的にして支承されている水産練製品原料製造装置。【選択図】図２
