1、- - I 年产 15000 吨婴儿配方粉工厂设计 摘 要 本设计主要是进行年产 15000 吨婴儿配方粉工厂设计。首先，在了解婴儿配方粉 市场的基础上，提出了建厂的可行性；其次，设计出了婴儿配方粉的配方和计算了生 产车间的物料衡算、热量衡算;另外，对车间的工艺设计和设备选型也进行了计算，为 了节约能源，特别采用了三效降膜蒸发器，设计了喷雾干燥塔。本设计对公用事业、 土建等方面也作了一个初步的设计方案。同时，对水、电、汽的用量和费用也进行了 估算；则日耗汽量大概为 700t，燃料费用约为 18200 元；日用电量 3738 度，费用约为 2429.7 元；日用水量 2000 吨，费用约为 40

2、00 元。最后，本设计还做了必要的技术经 济分析，全厂总投资 5862.5 万元,年上缴利润 1959.2 万元,投资回收期大概为 3 年。 整个设计充分考虑了目前的经济状况和今后发展的需要，从节能的角度出发选择 设备。生产流程充分考虑到机械化、自动化，技术上先进、可靠，布局合理规范。 关键词：婴儿配方粉；设计；三效降膜蒸发器 - - II Produce 15000 tons per year of infant formula powder factory design Abstract The design of annual output of 15000 tons infant fo
