How will you separate husk or dirt particles from a given sample of pulses before cooking?

(1) Husk or dirt particles can be separated by the winnowing method.

(2) Undesirable substances such as pieces of stone in the pulse or rice can be separated by hand-picking but the husk is mixed with the pulse then we separate it by winnowing.

(3) It is used to separate the heavier and lighter components of a mixture by wind or by blowing air.

(4) In this method, the mixture of husk and seeds of grains are taken on a plate and are made to fall down from a height up to our shoulders.

(5) As the mixture falls down, the lighter husk is taken away by blowing air and the heavier grain seeds fall down to make a heap.
