It is an object of the present invention to solve unevenness occurring in a processing cage of a food processing apparatus. An external water tank (14) in contact with the outside of the water tank (13) is provided, and a first water flow passage opening (55) through which a water flow from the external water tank (14) passes is provided near the water surface in the partition wall (56) The cage (12) is provided with a second water flow passage opening (42) through which the water flow from the first water flow passage opening (55) can be introduced, and in the outer water tank (14), the rotary water wheel (73) 56), and covers a rectifying section (74) for rectifying the upward water flow generated by the rotating water wheel (73) to the first water flow passage port (55).食品処理装置の処理籠内で生じる偏りを解決することを課題とする。水槽(13)の壁外に接する外水槽(14)を設け、この仕切壁(56)には水面近傍に外水槽(14)からの水流を通す第一水流通過口(55)を設け、処理籠(12)には第一水流通過口(55)からの水流を導入可能な第二水流通過口(42)が設けてあり、外水槽(14)には回転水車(73)が仕切壁(56)に沿って配され、回転水車(73)が発生させた上向きの水流を第一水流通過口(55)へ整流させる整流部(74)を被せる。
