PROBLEM TO BE SOLVED: To provide a shellfish sorting apparatus and a shellfish sorting method in which lightweight small shellfish can be sorted with high accuracy, although conventionally being performed in a small quantity by manual work.SOLUTION: A shellfish sorting apparatus 1 includes a container 10 capable of receiving water, and a sorting unit 20 disposed in the container 10 and having a sorting surface provided with multiple openings. The shellfish sorting apparatus 1 further includes a drive unit 30, and this drive unit 30 generates driving force for moving the sorting surface between a lower position and a higher position than a water surface. The shellfish sorting apparatus 1 further includes a water discharge unit 40, and the water discharge unit 40 discharges the water for moving the shellfish toward the sorting surface when the sorting surface is in a position higher than the water surface.SELECTED DRAWING: Figure 1【課題】従来は手作業で少量ずつ行わざるを得なかった軽量の小さな貝を精度良く選別することが可能な貝選別装置及び貝選別方法を提供する【解決手段】貝選別装置１は、水を収容することが可能な容器１０と、容器１０内に配置され、複数の開口が設けられた選別面を有する選別部２０とを備える。貝選別装置１は、さらに駆動部３０を備え、この駆動部３０は、選別面を水面より低い位置と高い位置との間で移動させるための駆動力を発生する。貝選別装置１は、さらに水放出部４０を備え、水放出部４０は、選別面が水面より高い位置にあるときに貝を移動させるための水を選別面に向けて放出する。【選択図】図１
