Methods of separating grain from chaff used by small scale farmers

    • How are the husk particles of grain separated?

      The husk particles are carried away by the wind. The seeds of grain get separated and form a heap near the platform for winnowing. The separated husk is used for many purposes such as fodder for cattles. Sieving Sometimes, we may wish to prepare a dish with flour.

    • When to use sieving to separate a mixture?

      Sieving is used when components of a mixture have different sizes. Sedimentation, Decantation and Filtration Sometimes, it may not be possible to separate components of a mixture by winnowing and handpicking. For example, there may be lighter impurities like dust or soil particles in rice or pulses.

    • How is Winnowing used to separate a mixture?

      This method of separating components of a mixture is called winnowing. Winnowing is used to separate heavier and lighter components of a mixture by wind or by blowing air. Fig. 5.4 Threshing threshing is done with the help of bullocks.

    • How is handpicking used in the separation of substances?

      This method of handpicking can be used for separating slightly larger sized impurities like the pieces of dirt, stone, and husk from wheat, rice or pulses (Fig. 5.3). The quantity of such impurities is usually not very large. In such situations, we find that handpicking is a convenient method of separating substances.
