What are the advantages of winnowing?

Winnowing is a process used to separate lighter materials from heavier ones, typically in agriculture for grain processing. Its advantages include the efficient removal of chaff and debris from harvested grains, resulting in cleaner and higher-quality produce. Additionally, winnowing can help improve storage longevity by reducing moisture and pest attraction, ultimately leading to better yields and profitability for farmers. Lastly, it can be done manually or with machinery, offering flexibility in its application.
