A rice polisher is a kitchen appliance dedicated to buffing (or "polishing") kernels of rice to improve their appearance, taste, and texture.
Rice polishers are abrasive machines that use talc or some other very fine dust to buff the outer surface of rice kernels.
In Japanese farming communities there is often a shared rice polishing machine.
In the 20th century consumer devices were created that allow individual cooks to polish rice in their homes.
