The separation process used for separating husk from grains is by winnowing and handpicking.
Various methods of separating the components from a mixture are present. In this method, heavier and lighter components of a mixture are separated by wind or by blowing air.
The husk particles are carried away by the wind. The seeds of grain get separated and form a heap near the platform for winnowing. The separated husk is used for many purposes such as fodder for cattle.
The dust particles are picked from the hand manually.
This method involves simply picking out all the unwanted substances by hand and separating them from useful ones.
