This study was to find out the relationships between whiteness, hardness, crack ratio, broken rice ratio, increased grain temperature, moisture content, electric energy consumption, and optimum conditioning of grain temperature for the milled rice efficiency and quality maintenance during the milling process of brown rice at low temperature. There was no significant difference between the whiteness variations of white rice after milling process when the conditioning grain temperatures ranging from 0 to 20oC was used. The crack and broken rice ratios of white rice and the hardness of brown rice decreased with an increased in the conditioning grain temperature. Conditioning grain temperatures of 12, 20oC are applicable to appropriated standard of temperature (15oC) after milling process. In the case of low temperature of grain, there was steadily increase the rate of changing moisture contents because of dew condensation. There was 2.62~14.28% decline of electricity energy for milling process when the temperature of grain was higher than 0oC. Therefore, it needs to control temperature over 10oC for appropriate milling in winter season.
