| 中文摘要: |
| 为了指导生产，实现膨化大豆粉生产线在线检测水分、粗蛋白质和粗脂肪含量，在膨化大豆粉生产线安装近红外光谱仪，并将在线检测数据与国标方法（人工取样）检测数据进行了对比。结果表明：在线近红外光谱仪测定膨化大豆粉样品的水分、粗蛋白质、粗脂肪含量结果与国标方法接近，符合国标允许误差要求；配套的全自动镜头吹扫系统可有效去除黏附在采集窗口上的膨化大豆粉，保证了检测结果的准确性。实践证明，将在线近红外光谱仪应用于膨化大豆粉生产上，完全能满足膨化大豆粉加工行业在线实时监控的需求。 |
| 英文摘要: |
| In order to guide for production and realize online detection of moisture, crude protein and crude fat contents in puffed soybean powder production line, a near infrared spectrometer was installed in the production line, and the online detection data was compared with that of the national standard method for manual sampling. The results showed that the results of moisture, crude protein and crude fat contents of puffed soybean powder detected by online near infrared spectrometer were close to those by the national standard method, and met the allowance error of the national standard. The fully automatic lens purging system could effectively remove the puffed soybean powder adhering to the collection window to ensure the accuracy of the detection results. Practice has proved that the application of the online near infrared spectrometer in the production of puffed soybean powder can fully meet the needs of online real-time monitoring. |
