年产20万吨淡色啤酒厂糖化车间糖化锅设计
摘 要
啤酒是仅次于水和茶的三大饮料，同时也是目前世界上消费量最大的酒精饮料。啤酒是用含有淀粉的谷类（主要是大麦）酿造而成的，多数添加啤酒花来调味。
本次设计是对年产20万吨淡色啤酒厂糖化车间糖化锅设计。主要包括啤酒生产的工艺流程设计，工艺计算，糖化车间物料衡算、糖化车间热量衡算（糖化用水消耗热量、第一次米醪煮沸消耗热量、第二次煮沸前混合醪升温耗热量、第二次米醪煮沸消耗热量、洗槽水耗热量、麦汁煮沸耗热量、糖化一次总耗热量、糖化一次耗用蒸汽量、蒸汽单耗），设备的设计与选型（主要设计糖化锅）等。

ABSTRACT
Beer ranked the third popular drink after water and tea, at the same time, it sells best among the world's alcoholic beverages. Beer is brewed from starch grains (containing is mainly a tons light beer workshop. Including the design of beer production process, calculation process, glycosylated plant material balance, workshop (calories for glycosylated water , for the first mash boiled rice , and the for the second mixed mash temperature before boiling of boiled mash, wash water tank of , steam consumption per unit), the design and selection for equipment (the main design is mash tun), etc..
Key words: beer calculation mash tun
