| 中文摘要: |
| 轧坯机是油料加工预处理工艺中的关键设备之一，轧坯机100％碾压是轧坯机最基础的功能，但随着其使用时间的延长，辊和挡料机构的磨损会导致漏料问题。对轧坯机漏料的原因进行了分析，采用FMEA工具，计算风险因素的RPN值，针对轧坯机100％碾压失效进行风险管控。结果表明：改进后风险控制各类漏料位置的风险因素都维持在5以内，RPN值降低至20以内，满足风险控制要求。对轧坯机进行改造升级后，成品粕残油从0.8%～1.1%降至0.6%～0.8%。 |
| 英文摘要: |
| 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%. |
