How can you separate husk from grains?

Husk can be separated from grains using the method of winnowing. This technique works on the difference in weight between the lighter husk and the heavier grains.

In this process, the mixture of husk and grains is dropped from a height or exposed to blowing air. The lighter husk gets carried away by the wind, while the heavier grains fall straight down and collect separately.

Farmers commonly use natural wind or a fan to perform this process after threshing.

In simple terms, winnowing uses air to remove the lighter husk from heavier grains efficiently.
