Abstract: The effect of moisture conditioning treatment on milling characteristic of brown rice was studied. Milling experiments were conducted for the brown rice(initial water content was 12.5%), which were conditioned under different amounts of humidification and duration. Software SAS was used to analyze the effect of amount of humidification and duration on the head rice yield and energy consumption of brown rice milled. The reasonable parameters including amount of humidification of 1.45% and duration of 60～90 min were obtained, which decreased energy consumption by 30% and increased head rice yield by 10%. Therefore, moisture conditioning treatment can improve milling quality of stored paddy due to the hardness and crispness of paddy reduced.
