what is winnowing and for what it is used
Answers
Wind winnowing is an agricultural method developed by ancient cultures for separating grain from straw. It can also be used to remove pests from stored grain. Winnowing usually follows threshing in grain preparation.
In its simplest form it involves throwing the mixture into the air so that the wind blows away the lighter chaff, while the heavier grains fall back down for recovery. Techniques included using a winnowing fan (a shaped basket shaken to raise the chaff) or using a tool (a winnowing fork or shovel) on a pile of harvested grain.
Answer:
Winnowing is used to separate heavier and lighter components of a mixture by wind or by blowing air. This process is used by farmers to separate lighter husk particles from heavier seeds of grain.
