Abstract: |
Flaker is one of the key equipments in the pretreatment process of oilseeds processing. The 100% rolling is the most basic function of the flaker, but with the time prolonging, the wear of the rollers and the blocking mechanism may cause leakage. The reasons for the leakage of flaker were analyzed. The RPN value of the risk factors was calculated by FMEA and the risk of 100% rolling failure of oilseeds flaker was controlled. The results showed that after the improvement, the risk factors of all kinds of leakage locations were kept within five, and the RPN value was reduced within 20, which could meet the risk control requirements. After the transformation of the flaker, the residual oil of the meal decreased from 08%-1.1% to 0.6%-0.8%. |
