PAGE 43 年产4000吨植酸酶发酵车间设计 摘要 本次设计是关于年产4000吨植酸酶的发酵车间设计。 在如今的食品加工工业中, 酶制剂的应用差不多在食品加工的各个领域中都有触及过。在面对酶制剂越来越好的应用上。植酸酶是一类催化植酸和植酸盐水解成无机磷和肌醇的酶。根据酶的性质和机理确定生产工艺流程，根据物料平衡选择合适发酵罐和种子罐。在此基础上得出所需的各种原材料的数量，计算得到了发酵罐、种子罐和通用设备，最后设计了发酵工厂的车间布局，根据计算结果，设计了三幅图，为发酵罐装配图、厂房车间布置图、物料流程图。 关键词：植酸酶发酵；工艺设计；衡量衡算。 The graduation projects mission is to make a production plant design, whose annual output is 4,000 tons of phytase preparation. Abstract This design is about the annual output of 4000 tons of phytase fermentation workshop design. In todays food processing industry, enzyme used in almost every field of food processing. In the face of more and more applications of enzyme preparation. Phytase is a kind of phytic acid and phytic acid catalyzed hydrolysis into inorganic phosphorus and inositol. The production process was determined according to the nature and mechanism of the enzyme, and the suitable ferment tank and seed tank were selected according to the material balance. On this basis, the quantity of various raw materials needed was obtained, and the fermentation tank, seed tank and general equipment were calculated. Finally, the workshop layout of the fermentation factory was designed. According to the calculation results, three drawings were designed, including the assembly diagram of the fermentation tank, the workshop layout diagram and the material flow chart. Key words: Phytase fermentation; Process design; Measure balance. 目录 TOC \o 1-3 \h \z \u 1前言 1 1.1植酸酶来源 1 1.2植酸酶的性质 1 1.3植酸酶的应用 2 1.4研究的现状及其意义 3 1.5设计目的 3 2发酵工艺 4 2.1植酸酶生产流程简介 4 2.2植酸酶固、液发酵法 4 2.2.1植酸酶固体发酵法 4 2.2.2植酸酶液体发酵法 5 2.3产植酸酶菌种的选育 6 2.3.1一级液体培养 6 2.3.2植酸酶发酵培养 6 2.3.3 植酸酶的分离纯化 8 3工艺计算 9 3.1发酵罐 9 3.1.1每天发酵罐放罐体积 9 3.1.2发酵罐的体积 10 3.1.3发酵工段所需的发酵罐台数 10 3.1.4发酵罐的物料衡算 11 3.1.5发酵罐物料消耗计算 12 3.1.6补料液中各物料的消耗量 15 3.2种子罐 17 3.2.1种子罐物料衡算 17 3.2.2种子罐公称体积 18 3.3热量计算 21 3.4水的用量 23 3.4.1自来水 23 3.4.2冷却用水 24 3.4.3实消过程冷却水用量 25 3.5蒸汽耗量计算 26 3.5.1直
