| 中文摘要: |
| 旨在为大豆低温粕加工厂冷却筛分工段工艺优化、设备选型及产品质量的提高提供参考，针对低温粕水溶性蛋白含量高、黏度大的特点，介绍了目前3种主要的大豆低温粕冷却筛分方式，即过桥冷干与旋振筛相结合的冷却筛分方式、圆锥滚筒筛冷却筛分方式、翻板冷却与圆筒筛相结合的冷却筛分方式，对这3种方式的工艺、主要设备结构及特点进行了阐述，并从大豆低温粕的冷却效果、筛分效果、粕片状保持度与碎料形成、水分损失、设备维护周期等方面进行了对比分析。根据3种冷却筛分方式的主要经济技术指标，采用评分法优选出翻板冷却与圆筒筛相结合的方式为最佳冷却筛分方式；该冷却筛分方式以其结构简单、处理量大、维修方便、冷却筛分效果良好等优点，可作为投资者的优先选择。 |

| The aim is to provide reference for the optimization of the cooling and screening process, equipment selection, and improvement of product quality in low-temperature soybean meal processing plants. In view of the high water-soluble protein content and high viscosity of low-temperature meal, three main cooling and screening methods for low-temperature soybean meal were introduced, namely combination of bridge-type cooler and dryer with vibrating screen, conical trommel screen cooling and screening, and combination of flip-flop cooler with trommel screen. The processes,main equipment structures and characteristics of these three methods were elaborated, and a comparative analysis was conducted from the aspects of cooling effect, screening effect, meal sheet retention and crushing formation, moisture loss of low-temperature soybean meal, and equipment maintenance cycle, etc. Based on the main economic and technical indicators of the three cooling and screening methods, the combination of flip-flop cooler with trommel screen was selected as the optimal cooling and screening method through a scoring method. The combination of flip-flop cooler with trommel screen has the advantages of simple structure, large processing capacity, easy maintenance, and good cooling and screening effect, and can be a preferred choice for investors. |
