| 中文摘要: |
| 异己烷因其毒性低、沸点低、馏程窄而备受关注。通过异己烷在5 000 t/d膨化大豆浸出生产线上应用实践，评价毛油残溶、湿粕残溶、蒸汽消耗、溶剂消耗、成品粕氮溶指数以及毛油磷脂含量的变化，并与正己烷的效果进行对比。结果发现，异己烷在膨化大豆浸出生产线的毛油残溶、湿粕残溶、成品粕氮溶指数、毛油磷脂含量及蒸汽消耗均优于正己烷，年均溶剂消耗与正己烷基本持平。建议加大对异己烷在浸出法制油中的推广应用力度。 |
| 英文摘要: |
| Isohexane has attracted much attention due to its low toxicity, low boiling point and narrow distillation range. Through the application practice of isohexane in 5 000 t/d extruded soybean extracting production line, the changes of crude oil residual solvents, wet meal residual solvents, steam consumption, solvent consumption, nitrogen solubility index of meal and phospholipid content in crude oil were evaluated and compared with the effects of n-hexane. It was found that the crude oil residual solvents, wet meal residual solvents, nitrogen solubility index of meal and phospholipid content in crude oil of extruded soybean extracting production line with isohexane were better than those with n-hexane, and the annual average solvent consumption was the same as that with n-hexane. It was suggested that the promotion and application of isohexane in oil leaching should be strengthened. |
