10万吨果葡糖浆厂的设计（毕业学术论文设计）.doc

PAGE 摘 要 果葡糖浆也称高果糖浆（High Fructose Syrup）或异构糖浆，是以酶法糖化淀粉所得的糖化液经葡萄糖异构酶的异构作用，将其中一部分葡萄糖异构成果糖，由葡萄糖和果糖而组成的一种混合糖糖浆。果葡糖浆最大优点在于含相当的数量 42%～90%的果糖，因而在甜味特性上与其他甜味剂共同使用，具有很好的协同增效作用，不仅可改善食品与饮料的口感，还可以减少苦味和怪味。果葡糖浆与蔗糖结合使用，可使其甜度增加20%～30%，而且甜味丰满、风味更好。果葡糖浆与甜蜜素、糖精等也有增效作用。果葡糖浆的主要成分和性质接近于天然果汁，具有水果清香，味觉甜度比蔗糖浓，且有清凉感。与蔗糖和甜菜糖比较，果葡糖浆具有溶解度高、易发酵、化学稳定性和热稳定性好、渗透压大、吸潮性和保湿性强等优点。在饮料等食品生产中有取代蔗糖的趋势，作为食品饮料基料的新型食糖果葡糖浆越来越被人们认可和重视。 本论文是设计年产100000吨果葡糖浆厂。以玉米淀粉为原料，本设计流程是采用双酶法工艺，其流程为原料→液化→糖化→脱色→离交→蒸发→异构→脱色→离交→蒸发，制成固形物含量为74%的F-42型的果葡糖浆。 本设计由四大部分构成：设计说明书 、工艺流程图、重点设备装配图以及生产车间设备布置图。论文完成了工艺流程的选定，物料、热量和水的平衡计算，设备选型等的工艺设计，同时对人员配备和三废处理提出合理的建议。 关键词：果葡糖浆；酶法工艺；工厂设计；蒸发浓缩 Abstract Fructose Syrup also called High Fructose Syrup or heterogeneous Syrup，it is enzymatic saccharification starch by glucose isomerase part of glucose, fructose it is a mixture of sugar syrup. Fructose syrup biggest advantage is that contain a considerable number 42 percent to 90 percent of fructose, thus in the sweet characteristic with other sweeteners on common use, and with advantageous synergistic effect, which can improve the taste of food and beverage, reduce the bitter taste and smell. Fructose syrup and sucrose use together, can make it sweetness increased by 20% ~ 30%. Fructose syrup and sweet element, cyclamates also have synergic. Fructose syrup near the main composition and properties of natural fruit juice, with fruit flavours. Flavour feeling, taste sweetness, and sucrose thicker than cool and refreshing feeling. Compared with sugar and beet sugar, fructose syrup is high, easy to ferment, solubility of chemical stability and good thermal stability, big osmotic pressure, moisture absorption and moisturizing strong sexual advantages. In beverages food production has replaced the trend of sucrose, as food and beverage makings of new it food candy grape syrup more and more recognized by people and attention, especially synergistic, cold sweet and refreshing features, highly popular drink factory. This design is an annual output of 90,000
