A mixture of wheat and husk can be separated by which process

Dear Student,
Winnowing is based on the principle that mixture contains two components one is lighter and the another one is heavier, then the lighter components can be separated by blowing air. The mixture falls from a height. The lighter component gets blown away due to wind.
Between wheat and husk, husk is the lighter component and wheat grains are heavier.
Thus the mixture can be separated by Winnowing
