Performance Evaluation and Improvement of Rice Polishers of Small and Medium Size(I)-rice polisher of small size-

중.소형 연미기의 성능평가 및 성능개선에 관한 연구 (I)-소형연미기에 대하여 -

Structural characteristic of a rice polisher of small size was analyzed to improve its performance and to utilize such data in developing a rice polisher of large size. Spraying characteristic of nozzles which were used for rice polishing was evaluated by a machine vision system. Internal pressure of the polishing chamber was also measured according to outlet resistance, water spraying, and roller shaft speed. In addition, the performance of the polisher was analyzed based on whiteness and broken ratio according to operating conditions.
