In villages, it is common to observe how women at home remove the husk from the grain. This method is known as:

🔑 Key Points
Solution
→ Winnowing: A method of separating components of a mixture by wind or air blowing, commonly used by farmers to separate lighter husk from heavier seeds. In households, it is used to separate grain from husk. The husk is carried away by the wind, and the seeds form a heap. The husk is used as fodder for cattle.

Explanation:
→ Sieving: Allows fine flour particles to pass through a sieve, while larger impurities like husk and stones are left behind. This is done in flour mills and construction sites.
→ Handpicking: Used for separating larger impurities like dirt, stones, and husk from wheat, rice, or pulses. This method is used when the impurities are minimal.
→ Threshing: A process to separate grain from stalks by beating the stalks to release the grain seeds. This can be done manually or with machines.

🔴 Additional Information:
→ Sieving is used in flour mills to remove impurities such as husk and stones before grinding wheat. In construction, it separates pebbles and stones from sand.
→ Handpicking is effective when the impurities are relatively few in quantity.
→ Threshing can be done with the help of bullocks or machines for larger quantities of grain.
