Abstract:

In order to explore the drying technology of rice grain, a text was conducted with 3 500 t newly acquired japonica rice, using corn hot-air dryer, and measured indicators of the water content, fatty acid value, color, odor, taste score before and after drying, as well as the correlations. The results showed that corn hot-air dryer could effectively reduce the water content of rice; there is no significant difference on the fatty acid value before and after drying, T test P value remains 0.706; taste score T test P value remains 0.788; color, odour and other detection indexes were normal after drying. From all aspects of indicators, using corn hot-air dryer to dry rice, could ensure that the rice grain reaches the safe storage standard, and guarantee the original quality of rice grain.
