The present invention cleans grains to remove foreign matter from grains such as soybeans. To achieve this, grain supply, grain washing, and grain drying work are done automatically. Conventionally, grains are supplied so as to be submerged in a bucket, and then the grain is washed first in a bucket, then secondly washed by a pump and a stirrer, and then the grains are cleaned by naturally dropping water. This has the problem that the grain is blown into the water and it takes much time to dry the washed grain. In addition, as water is transported through the grain, waste of water is serious. Therefore, the present invention has the purpose of washing cereals by spraying wash water, and drying by supplying warm air. In order to achieve the above-mentioned object, specifically, it comprises a grain supply part, a grain washing part and a drying part. The grain supply unit feeds the grain into the inside of the grain washing unit and supplies a certain amount of grain to the grain washing unit.
