Rice Huller

A rice huller, also called a rice husker, is a machine that removes the outer husk and chaff from harvested rice grains, work that was traditionally done by hand with a mortar and pestle before mechanical rice pounders and then hullers took over the task. The most widely used modern type is the Engelberg huller, designed by the German Brazilian engineer Evaristo Conrado Engelberg and first patented in 1885, which uses steel rollers to strip the husk from the grain. Other hullers use rotating disks or cones with abrasive surfaces, or rubber rollers that reduce grain breakage at the cost of needing frequent replacement, and such machines remain central to rice processing across Asia.
