1. Clean paddy after cleaning and destoning

The presence of poor-quality paddy lowers the total milling recovery. The impurities, straws, stones and small clays are all removed by cleaner and destoner, as well as those immature kernels or half-filled grains.

2. Brown rice after the rubber roller husker

Mixture of paddy grains and brown rice coming out of the rubber roller husker. With uniform size paddy, about 90% of the paddy should be de-husked after the first pass. This mixture goes through a paddy separator, after which the un-husked paddy is returned to the husker, and the brown rice goes to a whitener.

3. Milled rice after polishers

Milled rice after the 2nd stage friction whitener, and there is small broken rice. This product goes to a sifter to remove the small broken grains. Most rice milling lines have several polishing stages for gentle milling. In those mills there is undermilled rice after the 1st stage friction whitener, and not all the bran layers are fully stripped.
