To solve the problems that a long spindle at the center of a discharge part in a washing tank 1 makes an outlet narrow and comes into contact with grains to inhibit them from being discharged downward, thereby the discharge of the grains cannot be smoothly carried out, that a washing tank which must be divided when checked required to be dismantled every time the inside of the washing tank is checked, even if the check is simple, and the check requires a great deal of time and is carried out with low efficiency, and that the inside of a washing tank which is integrally formed and has a window cannot be sufficiently checked.
A grain washing device is composed of a washing tank 1 equipped with a washing means therein, a lifting and lowering value 2 capable of switching from a storage state where washed rice and water for rice cooking are stored in the washing tank 1, to a discharge state where they are discharged downward through the washing tank 1, wherein the lifting and lowering valve 2 is attached to an arm 3, which is installed on the outside of the washing tank and can be lifted and lowered.
