The process of threshing brings out grains from the cut and dried crop plants but this grain is mixed with chaff and hay and has to be cleaned by separating from chaff and hay before it can be used this is done by the process called winnowing. the process of separating grain from chaff and hay with the help of wind is called winnowing. when the grain mixed with chaff and hay is made to fall from a height in blowing wind , the grain , being heavy , falls straight to the ground , where is the chaff and hay , being much lighter, are carried some distance away by the wind. In this way the grains form a separate heat and can be collected and packed in gunny bags.

Wind winnowing is an agricultural method developed by ancient cultures for separating grain from chaff. It is also used to remove hay and chaff or other pests from stored grain.
