In order to play such a role, the scraper 22 is a rod of a predetermined length, and the front portion is made of a mesh 30 so as to pass the washing water and guide only grains in order to reduce the load due to the water pressure of the washing water. Further, it is preferable that the tip portion 22a is inclined at a predetermined angle to guide the grain more efficiently.

The operation of the grain washer 10 according to the present invention having the configuration as described above will be described with reference to FIG.

First, the grain to be washed is injected into the inner cylinder 14. Subsequently, the washing water is supplied to the inner cylinder 14 from the washing water supply pipe 31 installed at a predetermined portion of the outer case 11. The nozzle portion 31a is coupled to the end of the washing water supply pipe 31 so that the washing water can be evenly sprayed into the inner cylinder 14.

At the same time, power is supplied from the driving motor 19 coupled to the lower end of the rotary shaft 17 so that the rotary shaft 17 rotates. When the rotating shaft 17 is rotated, the grains in the interior of the screw barrel 16 is raised at the same time as the rotation at a high speed by the screw unit 15 formed on the outer peripheral surface of the rotating shaft 17. At this time, the outer surface of the screw portion 15 and the inner circumferential surface of the screw barrel 16 is formed with a plurality of protrusions 28, 27 to increase the frictional force of the grain during the rise to improve the washing force for the grain 100 You can.
