SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a grain cleaner capable of cleaning grain using dry air or wet air.

 Generally, in order to wash cereals such as beans, acorns, and banks, the grains are thawed and sifted through a sieve, and then the cereals are washed manually by immersing them in water together with water, There is still a problem in that the labor is entered and the washing state of the grain is poor and the grain is transported to a place where it is to be dried to remove the moisture remaining in the grain and the time and labor required for drying the grain are further increased.

 In order to solve the above problems, there has been proposed a device for washing cereals with the rotation of a screw in a washing tub receiving washing water for a washing operation. However, in order to remove moisture remaining in the grain, There is a problem in that the installation cost and the space for securing it are secured, and the productivity is reduced due to the time required for dewatering and drying, resulting in a decrease in work efficiency.

 In addition, since the grain is washed together with the washing water, after the washing of the grain, there is a problem that the grains are not discharged to the grain outlet due to the entanglement of the grains with water after draining the washed water, And the grains are deteriorated by bacteria when they are left in a non-dried state due to poor discharge.

 In order to solve the above problems, there is a device using dry air for separating foreign matter mixed with cereals without using washing water. However, it is possible to separate mixed foreign matters, There is still a problem in that it can not be effectively removed and it is necessary to perform cleaning again.
