1、10万吨/年10度纯生啤酒厂工艺初步设计摘要随着经济的发展，人们生活水平的不断提高，啤酒作为一种时尚消费品，已经为人们生活中不可或缺的商品。纯生啤酒作为一种口味更加纯正的饮料酒深受消费者的欢迎，其市场需求日益增加。本设计针对年产10万吨10度纯生啤酒厂工艺进行了初步设计。通过对工艺流程和工艺参数的确定，进行物料衡算、热量衡算、水平衡计算、耗电量计算、设备的计算与选型以及经济概算等。并在设备计算与选型基础上，绘制图纸。通过文献调研，确定了采用下面发酵法，以70%大麦和30%大米为原料进行为期20d（主发酵6d，后发酵14d）的分批式发酵。由物料衡算得出每年需大米4700t、
2、大麦11000t、酒花2350t；由热量衡算得出每年消耗蒸汽4.93×107kg；由水衡算得出每生产1t成品啤酒需耗水6.05t，年耗水量为599700t；由耗冷量的计算得出每年耗冷1.337×1010kJ。并且通过对设备的选型与计算得出需要112.4m3的糖化锅1个，924m3的圆筒体锥底发酵罐20个，.另外还需要21圈，分为3组的换热管。关键词：纯生啤酒；工艺设计；物料衡算；热量衡算；圆筒锥底发酵罐iThepreliminarydesignof10ºPpuredraftbeerfactorywithanannualoutputof100000tonsAbstractW
