确切地掌握粮食的质量可增加农民的收益。含油量高的稻谷和含蛋白质多的小麦要价更高。目前测量粮食含油量和蛋白质含量的方法基于反射的近红外辐射,这需要一些半敞开的仪器,这些仪器的成本高达6万美元,而且经常需要定标。由于这些固定的仪器一次装料只能测量少量样品,测量的结果只能说明代表整批粮食的样品的质量如何。 一种更好的系统应能在收割过程中对粮食进行连续的测量,从而使高质量与低质量的粮食直接分开入 Exact control of the quality of food can increase the income of farmers. High oil content of rice and protein-rich wheat asking for more. The current method of measuring grain oil content and protein content is based on reflected near-infrared radiation, which requires semi-open instruments that cost as much as $ 60,000 and often require calibration. Since these fixed instruments can only be used to measure a small number of samples at a time, the results of the measurement can only indicate the quality of the sample representing the entire batch of foodstuffs. A better system should be able to measure food continuously during the harvest so that high quality and low quality food are directly separated into
