| 中文摘要: |
| 以花生仁为对象，CF7+色选机为色选设备，研究色选机振动频率、病斑值、灵敏度等工作参数对色选机选净率、带出比的影响，以及色选工序前后花生仁纯质率、霉变率的变化。由正交试验得到花生仁色选的最优工艺条件为振动频率50 Hz、灵敏度10、病斑值120，在此条件下选净率达到99.84%、带出比为41。通过色选，花生仁的纯质率由94.22%提高至97.99%，霉变率由0.85%大幅度降低至0.04%，大大提高了花生仁的品质和食用安全性。 |
| 英文摘要: |
| Taking peanut kernel as the object, the effects of vibration frequency, disease spot value and sensitivity of CF7+ electro-optical sorter on the sorting net rate and error-sorting rate of sorter, and the pure rate and mildew rate of selected peanut kernel before and after the electro-optical sorting procedure were studied. The optimal conditions of sorter for peanut kernel were obtained by orthogonal experiment as follows:vibration frequency 50 Hz, sensitivity 10 and disease spot value 120. Under these conditions, the sorting net rate and error-sorting rate were 99.84% and 41, respectively. Through electro-optical sorting procedure, the pure rate of peanut kernel increased from 94.22% to 97.99%, and the mildew rate sharply reduced from 0.85% to 0.04%, which greatly improved the quality and safety of peanut kernel. |
