Drying process of mixed and process certification in infant and follow-up formula milk powder

目的对婴幼儿配方乳粉的干法工艺进行了工艺验证研究,旨在为相关干法工艺的生产企业提供理论与实践依据。方法通过分析工艺的主要关键点,确定从物料平衡、混合均匀、营养素符合和工艺稳定性4个方面进行工艺验证研究。结果该生产工艺条件下,物料的投入产出比在99.76%~100.31%,符合物料平衡的要求;不同位置的营养素指标相对标准偏差均值在3.03%以内,具有很好的混合均匀性;终产品的营养素偏差在10%以内,符合法规和设计要求;批次间的相对标准偏差也在5%以内,拥有很好的工艺稳定性。结论该工艺能满足婴幼儿配方乳粉的生产。

Objective To verify the drying process of mixed for infant and follow-up formula milk powder, in order to provide theoretical and practical basis for dry process manufacturing enterprises. Methods Throughanalyzing the critical point of technology in the process of dry mixing method for infant formula, 4 aspects such as material balance, mixing uniformity, nutrients compliance and process stability were confirmed to verify the drying process. Results Under the production process conditions, material input and output ratio ranged from 99.76% to 100.31%, which can meeting the requirements of material balance. The relative standard deviation（RSD） of nutrient indexes average value from different position was within 3.03%, so it had good mixing uniformity. The RSD of nutrient deviation of end products was within 10%, and it met the requirements of the laws and design. The RSD between batches was within 5%, which proved the process was stable. Conclusion This drying process of mixture can satisfy the production of infant and follow-up formula milk powder.
