| 为提高水代法芝麻香油生产效率，以卧螺离心代替传统水代法提油中的晃油、墩油工序，探索芝麻香油水代法连续化生产新工艺，在考察离心可行性及确定模拟连续离心条件基础上，对磨酱和兑浆搅油工序工艺参数进行了优化，并采用三相卧螺离心机对优化工艺进行实际生产验证。结果表明：兑浆搅油过程中整个体系的黏度都低于25 000 Pa·s，符合卧螺离心机对物料流动性的要求；芝麻香油水代法连续化生产新工艺最佳条件为砂轮磨1次+胶体磨1次磨酱、兑水量85%、高速（300 r/min）剧烈搅拌40 min+慢速（60 r/min）温和搅拌10 min、离心速度6 000 r/min、离心时间1 min，在此工艺条件下提油率为（89.28±0.45）%，芝麻渣残油率为（11.92±0.25）%；生产实验验证得到水代法连续化生产新工艺的提油率为（84.74±0.62）%，芝麻渣残油率为（15.61±0.28）%、粗蛋白质含量为（43.30±0.54）%、含水量为（59.40±0.26）%，芝麻香油除不溶性杂质和水分及挥发物含量外，其他指标均符合GB/T 8233—2018要求。综上，新工艺可实现芝麻香油的连续化生产，节省时间，且提油效果和芝麻香油质量指标与传统水代法接近，说明以卧螺离心为关键的水代法新工艺替代传统水代法工艺是可行的。后续将在中试及更大规模上进行装备升级和工艺优化研究，提升芝麻香油水代法连续化生产新工艺的效果。 |

| In order to improve the production efficiency of fragrant sesame seed oil by aqueous extraction method, instead of shaking oil and pounding oil process in oil extraction by the traditional aqueous extraction method, horizontal screw centrifugation was used to explore a new continuous process for fragrant sesame seed oil by aqueous extraction method. On the basis of examining the feasibility of centrifugation and determining the basic conditions for simulation continuous centrifugation, the parameters of grinding and water adding and mixing process were optimized, and the optimized process was verified by three-phase horizontal screw centrifuge in the actual production. The results showed that the viscosity of the whole system during the process of water adding and mixing was lower than 25 000 Pa·s, which was in line with the requirements of horizontal screw centrifuge on the fluidity of materials. The optimal conditions for new continuous process of fragrant sesame seed oil by aqueous extraction method were wheel mill + colloid mill grinding each once, 85% of water amount, high-speed (300 r/min) vigorous mixing 40 min, slow-speed (60 r/min) gentle mixing 10 min, centrifugal speed 6 000 r/min, centrifugal time 1 min. Under the optimal process conditions, the oil extraction rate was (89.28±0.45)%, and the residual oil rate of sesame residue was (11.92±0.25)%. The actual production results showed that the oil extraction rate of the new continuous process of aqueous extraction method was (84.74±0.62)%, the residual oil rate, crude protein content and water content of sesame residue were (15.61±0.28)%, (43.30±0.54)% and (59.40±0.26)%,respectively, and the fragrant sesame seed oil produced was in compliance with GB/T 8233-2018 except for the content of insoluble impurities and water and volatiles content. In conclusion, the new process can realize the continuous production of fragrant sesame seed oil, save time, and the oil extraction effect and fragrant sesame seed oil quality indexes are close to those of the traditional aqueous extraction method, which indicates that it is feasible to replace the traditional aqueous extraction process by the new process with horizontal screw centrifugation as key. Subsequently, it is necessary to carry out research on equipment upgrading and process optimization in the pilot test and on a larger scale in the future, so as to improve the effect of the new continuous process of fragrant sesame oil by aqueous extraction method. |
