The objective of commercial rice milling is to reduce mechanical stresses and heat buildup in the grain, thereby minimizing grain breakage and producing uniformly polished grain. Compared to villagelevel systems, the commercial milling system is a more sophisticated system configured to maximize the process of producing wellmilled, whole grains.

The seeds of the rice plant are first milled using a rice huller to remove the chaff (the outer husks of the grain) (see: rice hulls). At this point in the process, the product is called brown rice. The milling may be continued, removing the bran,, the rest of the husk and the germ, thereby creating white rice.

The process of removing the husk and bran layers, and producing white rice kernel that is free of impurities is referred to as rice milling. Usually, the three methods of purifying the rice are a onestep process where husk and bran removal are done together, a twostep process where husk and bran are removed separately, and a multistage process in which rice undergoes a series of different ...

The final step in growing rice is milling, a mechanized process that American mills have perfected. At the mill, the harvested "rough rice" passes through sheller machines to remove the inedible hulls. This process yields brown rice with the bran layers surrounding the kernel still intact. Brown rice can be used as is or further milled by ...
