Winnowing machine

• Winnowing is a process by which chaff is separated from grain, it is done after threshing of grains is done.
• It separates heavier and lighter components  of a mixture by wind or blowing air.
• For small amount of grains, traditionally it was done manually, but for large farm to harvest crops quickly and efficiently , we need winnowing machine or fanning mills.
