The machine is mainly used to make white rice from paddy rice, and together separate chaff from white rice. So the production rice has clean surface, low temperature and little chaff. The machine can adopt emery roll, iron roller or NBR roller to act as parts, so you can get different standards grade rice by use of the single machine. When you adopt the iron roller, you can still polish the wet rice. The machine belongs to the equipment of processing high standards rice. You can use the single set of NF machine to polish the paddy rice. And to increase the productivity, you can also use several sets of machines together in series connection (i.e., concatenation) to polish.
