Question

Name and describe briefly a method that can be helpful in separating a mixture of husk from grains. What is the principle of this method?

Answer 1

Winnowing technique:

1. Winnowing is a technique used to separate husks from grains.
2. Winning is started by the wind where the lighter particles are blown out of the food as the wind blows.
3. A winnowing basket is used to shake the husk.
4. Grains are heavy particles and fall to the ground vertically from the winnowing basket.
5. As a result, the husk is separated from the grain.
6. Winning depends on the weight of the particles.
7. Winnowing is carried out after threshing.

Winnowing technique principle:

1. If the mixture has two components and one is lighter than the other, the two components can be separated by air blow.
2. In this process, the mixture is lowered from a height.
3. The light component separates from the heavy component due to wind.
