2. Grain reached to the inner cylindrical type drum while the sieve structure of the inner cylindrical type drum remove the first category of unwanted material by the rotation action and sieve characteristics of the inner cylindrical type drum.
3. Then Grain reached to the outer cylindrical type drum while the sieve structure of the outer cylindrical type drum remove the Second category of unwanted material by the rotation action and sieve characteristics of the outer cylindrical type drum.

As another embodiment of the present invention , it disclose double cylindrical sieve rotated on the concentric axis using a hand operated means. The outer cylindrical sieve is removable according to the type of grains. The inner The outer cylindrical sieve is adapted to receive the grains with impurities and unwanted substances. The apparatus is made of the metal.
As another embodiment of present invention, it present an apparatus for grain cleaning with a double-layered cylindrical sieve operated through human power without any electricity. The electricity may use to replace to the human power by using electric motor. Figure 2 shows the an another sketch representation of the portable & low cost apparatus for cleaning and grading all type of grains, as a one of the embodiment according to the present invention.
The present apparatus having a double cylindrical sieve l, wherein said double cylindrical screen comprising a main frame mounted above the main frame impurity duct and the sieve, the sieve is attached to the top cover above the body outside said screen body by the inner screen cylinder and the inner screen cylinder provided outside the screen cylinder composed of .The inner cylindrical drum sieve is made as a fine mesh sieve and fine surface composition, the outer cylindrical sieve by a thick and replaceable The apparatus having a grain inlet side & grain outlet side.
