Answer 2

Harvested grains are threshed(removing the husk and straw from grains).after threshing the grains are winnowed using using traditional winnowing tool or nowadays winnowing machine.

It is the process of separating grain from the chaff.

Winnowing is done by making the wind blow through the grains, the chaff being lighter bluw away with the wind whereas the grain being heavier fall near the ground.
