In this research, rice milling technology for the germ-remained rice was explored based on the rice cultivars which were large area planting in northeast of China. Milling time, mesh number, rotational speed and length-width ratio of rice in milling were selected as the experimental parameters, while the quadratic orthogonal rotation experiments, response surface method and regression equation were used to analyze the variation of whiteness and rice germ reserved rate of germ-remained rice affected by the parameters. The results suggested that, the roller mesh number was an important element that affect the whiteness and germ reserved rate. Rotational speed and milling time were less important. Rise of length-width ratio would lead to rise of whiteness while the germ reserved rate decreased gradually. As a result, the best rice milling techniques is as follows: milling time 6 min, length-width ratio of rice 1.79, the roller mesh number 46#, rotational speed 830 r/min.
