文档介绍：摘要
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,其市场需求已经越来越大。本论文综合运用了大学期间所学的各个学科,针对年产20万吨纯生啤酒的发酵工艺进行了设计。通过参阅大量的国内外文献,确定了采用下面发酵法,以70%的大麦和30%的大米为原料进行为期20天(主发酵6天,后发酵14天)的分批式发酵。由物料衡算得出每年需大米9410t、大麦22000t、酒花4700t;;,年耗水量为5026608t;。,,分为3组的换热管

Abstract
As a taste of draft beer to drink wine more pure ed by consumers and its market demand has been increasing. In this paper, various disciplines learned in university is integrated for the technological design of beer fermentation process with annual output of 200,000 tons. According to the large number of domestic and foreign literature, 70 percent of the barley and 30 percent of the rice is identified as raw materials and taken it in batches fermentation by the following fermentation for 20 days (the main fermentation 6 days, 14 days latter fermentation). Drawn from the material balance,
9410t rice,22000t barley and 4700t hops is needed yearly; drawn by the heat balance, annual consumption of steam is ×107kg; drawn from the water balance, tons beer is consumed for 1 ton, the consumption of total water is 5026608 tons per year; by the calculation of cold consumption , ×1010 kJ of cold is needed yearly. Through the selection of equipment, we can deduce that a pot of glycosylated with , 40 Conical bottom cylindrical fermentation tanks with 924m3 needed and also need 21 circles, divided into 3 groups of tubes.
Key Words:draft beer; process design; material cross-operator; heat cross-operator; Fermenter conical bottom cylinder
