How to separate grain and husk?


Open in App
Solution

Separation of grain and husk:

  1. Techniques for separating two different states of matter, like liquid and solid, are called separation techniques.
  2. Two examples of separating methods are filtration and evaporation.
  3. Husk and grains are separated from each other via handpicking and winnowing, respectively.

Winnowing:

  1. The components of a mixture can be separated using a variety of techniques.
  2. In this approach, the heavier and lighter parts of a mixture are separated by wind or blowing air.
  3. The husk fragments are carried away by the wind.
  4. The separated grain seeds are amassed in a pile not far from the winnowing platform.
  5. The husk that has been extracted is used for a variety of things, including animal feed.
  6. Winnowing is a technique used by farmers to remove the grain seeds from the lighter grain husks.
  7. Pests in stored grain can also be eliminated using this technique.
  8. The mixture is thrown into the air, and the lighter chaff is then blown away by the wind.

Handpicking:

  1. The dust is meticulously removed from the hand.
  2. This process involves hand-picking out all the harmful components and separating them from the helpful ones.
  3. Both of the separated components might be helpful, or they might be an impurity that needs to be removed.
  4. For example, you may separate the black grapes from the green grapes in a batch of both.
