Rice polishers are used after the rice has gone through the whitening process.

Components
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.

Types
There are two types of polishing machines:


 * Vertical cone polisher: This machine uses a covered cone within a perforated screen to create an abrasive surface for polishing rice.
 * Horizontal polisher: This machine uses a cylinder covered in emery that is placed within another cylinder and rotated to polish the rice.
