Abstract: An innovative design of rice polisher with intelligent dampening and pressure control system was made for the purpose of modern high-capacity industrialized rice processing technology and at the aim of the realization of polishing operation with higher efficiency, better quality and lower exhaust by use of the integration of the mechanical, electrical, hydraulic and pneumatic, computer and so on. The combination of two polishing segments with different parameters was applied to obtain optimum polishing effect and to improve the adaptability of polisher to grain variety. An atomization dampening system with an intelligent water quantity control outside the polishing chamber was developed to ensure the moisture content of the grain under the condition of the optimum operation. A new mixing device of the moisture and grain was designed to decrease the break yield and accelerate the transmission between moisture and grains. In addition, the fuzzy control over the polishing chamber pressure and the pneumatic system with positive and negative air-stream was adopted to get better performance of the equipment and the better product quality of the polished rice. The application of MPG21/18 polisher has demonstrated the better operation behavior and the availability in modern rice processing industry.
