英文摘要:

      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 Through analyzing 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.
