A rice polisher is a machine for polishing kernels of rice to change their appearance, taste, and texture or for transforming brown rice into white rice.
Rice polishers are used after the rice has gone through the whitening process.
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.
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. The suction fan also catches any loose talc or dust that is lost throughout the process.
