Arice polisher is a machine for buffing (or "polishing") kernels of rice to change their appearance, taste, and texture or for transforming brown rice into white rice.[1][2]
Rice polishers are used after the rice has gone through the whitening process.[3] They 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. The first fully automated rice polishing machine is believed to have been patented by the English engineer and inventor Sampson Moore in 1861.[4] In the 20th century, kitchen appliances for consumers were created that allowed individual cooks to polish rice in their homes.[citation needed]
The polisher contains cones covered with leather strips and perforated screens. The leather strips on the cones rub the grain of rice over the screen repeatedly. The remaining particles on the rice are removed during this process, giving the grain of rice a shinier appearance.[3]
There is a suction fan within the polisher that keeps the rice cool as it travels through the polishing process and lowers the percentage of broken rice.[5] The suction fan also catches any loose talc or dust that is lost throughout the process.[6]
