A rice whitener, also commonly referred to as a rice polisher, is a crucial machine utilized in the rice milling process after the initial husking stage (which produces brown rice). Its primary function is to remove the brownish outer layer known as bran, as well as the germ, from the brown rice grains. This process is typically achieved through abrasion (using abrasive rollers or stones) or friction (rubbing the grains against each other and/or metal surfaces under pressure), which grinds or rubs off the bran layers. The result is the familiar white, polished rice that is the preferred form for consumption in the Philippines and many other parts of the world. Rice whiteners are essential equipment found in virtually all rice mills, from small local operations ("kiskisan") to large commercial facilities throughout Koronadal City and the SOCCSKSARGEN region, playing a key role in preparing the nation's staple food for the consumer market. The intensity of the whitening process can be adjusted to produce different degrees of milled rice.
