马铃薯淀粉生产车间的设计 摘 要：马铃薯是营养价值极高的产品，本项目立足于资源优势，对马铃薯进行深加工，其发展前景广阔。项目符合国家产业政策和山西省农村经济发展政策要求。 目前我国马铃薯大多作为鲜食,工业化加工转化率不到5%,而发达国家高达80%以上。这一方面说明我国马铃薯产业化的水平很低,同时也说明了马铃薯产业中蕴含着巨大的潜力。因此大力发展马铃薯产业是农业产业结构调整和增加农民收入的重要途径。 本设计是对日产30吨马铃薯原淀粉的车间进行设计。在设计过程中，从产品特性和市场预测的角度开展了研究，对马铃薯淀粉加工过程进行了详细的工艺论证，对每个工艺过程进行分析，并且在此基础上进行了物料衡算、热量衡算、确定原辅材料用量以及水、电、汽的耗量等。对主要设备进行了选型，最后进行了投资估算、成本核算和经济分析。分析结果显示：该项目年获利3010.32万元，投资回收期需2.93年,经营安全率高达58.81%。 关键词：马铃薯淀粉；生产工艺；设备选型；经济分析 Plant design of potato starch Abstract: Potatoes are very high nutritional value of products, the project based on the resources of potato processing, and its development prospects.Project conforms to the national industrial policy and policy requirements of the Rural Economic Development Most of our country as fresh potatoes, industrial processing and conversion rate of less than 5%, while the developed countries, more than 80%.This shows on the level of the potato industry in China is very low, but also illustrates the potato industry contains a huge potential.Therefore, to develop the potato industry is the agricultural industry and an important way to increase income of farmers. The product line design of 30 tons of potato starch daily is designed. In the design process, from product characteristics and market forecasts point to a feasibility study, carried out a detailed technical feasibility studies, the analysis of each process, and on this basis for the material balance, energy balance, determine the amount of auxiliary materials and water, electricity and steam consumption, and so on. Selection the main equipments, final investment estimate, cost accounting and economic analysis were done. The results show that: The project gain 30.1032 million Yuan of profits per year, investment recovery period is 2.93 years, operating safety rate as high as 58.81 percent.
