Answer» Winnowingis afarmingmethod developed byancientpeople for separatinggrainfromchaff. It is also used to removeweevilsor otherpestsfrom stored grain.Threshing, which is the loosening of grain orseedsfrom thehusksandstraw, comes before winnowing. In its simplest form it involves throwing the mixture into the air so that the wind blows away the lighter chaff. The heavier grains fall back down for recovery. This method is called "wind-grading".Other methods include using a winnowing fan (a shapedbasketshaken to raise the chaff).]Yet another is using a tool (a winnowing fork or shovel) on a pile ofharvestedgrain. Winnowing can also describe the natural removal of fine material from a coarsersedimentby wind or flowing water. This is similar to separatingwheatfrom chaff. |
