中国是稻谷生产和消费大国,为保障稻谷产后储藏安全,红外辐射技术被逐步应用。本文通过研究不同红外处理条件下(辐射强度和处理时间)玉米象致死率和稻谷品质的变化,发现玉米象成虫的热死亡曲线最符合0.5阶动力学反应模型,对应R~2为0.991 0,拟合效果良好。在0.5阶动力学反应模型预测下,红外辐射强度2125、2 780和3 358 W/m~2处理玉米象成虫达到99.99%的死亡率所需最短处理时间分别是111.43、28.02和9.73 s。与此同时,合适的红外辐射处理可以有效保证稻谷出糙率、整精米率和爆腰率等加工品质不受影响。上述结果证实,红外辐射技术可在短时间实现玉米象成虫致死,并有效保证了稻谷品质,提高稻谷产后加...

China is a big country of rice production and consumption.Infrared radiation technology is gradually used to ensure the post-harvest storage safety of paddy rice In this paper,by studying changes in Sitophilus zeamais lethality and rice quality under different infrared treatment conditions (radiation intensity and treatment time),it is found that the thermal death curve of Sitophilus zeamais adults conforms best to the 0.5 order kinetic response model,corresponding to R~2 of 0.991 0 with good fitting effect.Based on the prediction of the 0.5-order kinetic response model,the shortest treatment ...
