To properly remove mud adhering to crops in a water tank.SOLUTION: A crop washing device includes a water tank 7 that receives crops 2 from a charging and supplying device 6 and a water flow generation device 16 for generating a water flow from a starting end side on one side of the water tank 7 toward a terminal side on the other side. The water flow generation device 16 is composed of injection nozzles 17a, 17b, and 17c disposed vertically on the starting end side on one side of the water tank 7. The crop washing device includes a remaining crop feeding device 21 that moves from the starting end side toward the terminal side in the water tank 7. The remaining crop feeding device 21 is formed of a net body 22b.SELECTED DRAWING: Figure 4【課題】水槽で良好に作物に付着する泥土を除去しようとする。【解決手段】投入供給装置６の作物６を受ける水槽７を備え、水槽７一側の始端側から他側の終端側に向けて水流を起こす水流発生装置１６を設けた。水流発生装置１６は、水槽７の一側始端側に上下に配置した噴射ノズル１７ａ，１７ｂ，１７ｃによって構成される。また水槽７内において始端側から終端側に向けて移動する残果送り装置２１を設け、この残果送り装置２１を網体２２ｂで形成した。【選択図】図４
