为探讨稻谷保质烘干技术，应用玉米热风干燥机，对3500 t新收购粳稻谷进行1个月烘干作业，并对稻谷样品烘干前后的水分、脂肪酸值、色泽气味、品尝评分值等指标进行了测定和相关分析。结果表明，应用玉米热风干燥机烘干能够有效降水；烘干前后脂肪酸值T检验P=0.706，无显著差异；品尝评分值T检验P=0.788，无显著差异；色泽气味等检测指标在烘后均正常。可见，应用玉米热风干燥机烘干稻谷能够确保稻谷达到安全储藏标准，并可保证入仓稻谷的品质。

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.
