Solution:
Larger dirt particles present in the pulses can be easily removed by handpicking.Hand-picking is the method in which particles in the mixture can be separated by just picking them out with the help of a hand. If the dirt particles are smaller, like husk, they can also be removed by winnowing. In this process, pulses are allowed to fall from a certain height. The husk is lighter than the pulses, it is removed efficiently by air blow.
