Question Statement:

In rice milling, the rubber roll sheller is used for:

Options:

  • (A) Separating paddy from brown rice
  • (B) Removal of bran adhering to rice kernels
  • (C) Separating husk layer from paddy grains
  • (D) Removal of husk layer from white rice

Official Answer Key:

C

Step-by-Step Solution & Explanation

The rubber roll sheller (dehusker) removes the outer husk from paddy grains to produce brown rice. Separating unhulled paddy from brown rice (after shelling) is done by a paddy separator; bran removal (polishing) uses a rice whitener/polisher — not the sheller.
