Modern Rice Milling Process Steps & Paddy Rice Milling Systems Flowchart

Milled Rice is produced in rice mills after removing bran, husk and germ. Modern rice milling produces rice with different flavor, appearance (whiter) and extended shelf life.

What is Rice Milling?

Rice milling is all about producing edible milled rice after separating the husk (20%), the bran layers (11%) and clean rice (69%). In an ideal milling process this results in 20% husk, 8-12% bran depending on the milling degree and 68-72% milled rice.

7. Mist polishing
8. Rice weighing and packing

Rice Pre-cleaning Process

Paddy always comes with external materials including weed, soil, seeds, etc. These need to be removed before hulling. The capacity of the paddy pre-cleaner is 1.5 times the milling capacity.

Rice Cleaning Process

Removing the Husk (Dehusking or Dehulling)

Brown rice is produced by removing the husk from rough paddy rice using friction between two abrasive surfaces moving at different speeds. The husk is then removed by suction.

Whitening or Polishing

White rice is produced by removing the bran layer using abrasive or friction polishers. The amount of bran removed is normally 8-10% of the total paddy weight.
