| 中文摘要: |
| 旨在提高大豆分离蛋白生产车间的智能化水平，减少人工操作，提高产品稳定性，降低车间的不安全因素，在大豆分离蛋白车间现有自控水平上，针对酸沉工段中蛋白液pH检测值波动、失准，造成自控系统无法正常运行，影响产品得率，需要工人定时取样校对和调整，及干燥系统没有实现智能化一键启动，人工启动工序复杂，存在预热不彻底损坏加热器、干燥塔压力控制不当损坏干燥塔的问题，提出智能化解决方案，即在酸沉工段pH计自动反冲洗系统中，采用两种冲洗液（碱液+工艺水）进行自动定时冲洗，并编制了pH计自动反冲洗系统智能化控制程序，在干燥系统中结合现场实测结果开发了干燥系统一键启动智能化控制程序。通过工艺改进和智能化控制程序的应用，可降低生产线的不安全因素，有效避免人员和设备安全事故的发生，有力推动车间向安全、高效、智能化方向发展。 |
| 英文摘要: |
| Aiming to improve the intelligent level of soybean protein isolate production workshop, reduce labor input, enhance product stability, and reduce potential safety hazards in the workshop,based on the workshop′s existing automatic control foundation, for the inaccurate fluctuation of protein solution pH values in the acid precipitation section, which leads to malfunctioning automatic control and affects product yield, workers need to take samples regularly for calibration and adjustment. Additionally, the drying system is lack of intelligent one-key start function, leading to complex manual start-up procedures that results in incomplete preheating, damage to heaters, and poor pressure control in the drying tower, causing damage to the drying tower. To address these problems, intelligent solutions were proposed: in the automatic backwashing system of the pH meter in the acid precipitation section, two flushing liquids (alkali + process water) were used for automatic timed flushing,and an intelligent control program for the automatic backwashing system of the pH meter was developed. In the drying system, based on actual measurement results from the site, an intelligent one-key start control program for the drying system was developed. Through process improvements and the application of intelligent control programs, unsafe factors in the production line can be reduced, effectively preventing personnel and equipment accidents, and strongly promoting the development of workshop towards safety, efficiency, and intelligence. |
