摘　　要：[目的]通过单因素试验和正交试验设计,对低温牛乳污垢的清洗参数进行优化研究。[方法]选用未经加热处理的生牛乳原料,在不锈钢片上制作低温牛乳污垢,利用复合碱性清洗剂清洗。研究清洗剂有效浓度、温度和磁力搅拌转速。[结果]在清洗剂有效浓度0.3%、95℃温度、350 r/min磁力搅拌转速下,去污力最高。正交试验进一步验证单因素试验结果,确定最佳清洗参数组合为清洗剂有效浓度0.3%、温度90℃、磁力搅拌转速300 r/min。[结论]优化后的清洗参数能显著提高低温牛乳污垢清洗效率,对提升乳品加工行业清洗技术和产品质量有重要意义。未来可进一步探索更环保、安全的清洗技术,促进乳品加工行业可持续发展。[Objective]To optimize the cleaning parameters for low-temperature milk soil by single-factor experiments and orthogonal test design.[Method]Fresh raw milk without heat treatment was selected to create low-temperature milk soil on stainless steel plates,which were then cleaned with a composite alkaline detergent.The effective concentration,temperature,and magnetic stirring speed of the detergent were studied.[Result]The highest soil removal was achieved at an effective concentration of 0.3%,a temperature of 95°C,and a magnetic stirring speed of 350 r/min.Orthogonal tests further verified the results of the single-factor tests,determining the optimal cleaning parameter combination to be an effective concentration of 0.3%,a temperature of 90°C,and a magnetic stirring speed of 300 r/min.[Conclusion]The optimized cleaning parameters can significantly improve the cleaning efficiency of low-temperature milk soil,which is of great importance for enhancing the cleaning technology and product quality in the dairy processing industry.Future research can further explore more environmentally friendly and safe cleaning technologies to promote the sustainable development of the dairy processing industry.
