《啤酒厂的设计.doc

摘要 本设计为年产15万吨11°（淡爽型）啤酒厂设计，糖化工段的工艺设计是设计的重点。该啤酒经过糊化，糖化，过滤，煮沸，冷却，采用圆筒体锥底发酵罐，历经14天发酵而成。此次设计计算主要包括物料衡算，热量衡算，冷耗计算和设备选型的计算以及重点设备糊化锅的计算。该啤酒厂设计的图纸主要包括糖化车间和发酵车间的流程，重点设备糊化锅装配图，以及糖化车间的平面图和立面图。 啤酒的酿造采用70%的优质麦芽，30%的大米。设计中采用湿法粉碎，该工艺可以使麦芽皮壳充分吸水变软，粉碎时皮壳不易磨碎，胚乳带水碾磨，较均匀，糖化速度快，可提高过滤速度。对大米来说，粉碎的越细越好，越利于糊化。而湿法粉碎恰恰能更好的更细的粉碎。糖化采用二次煮出糖化法，用此方法酿造啤酒，其颜色色泽淡黄，泡沫丰富持久具有特殊味道。可以补救一些麦芽溶解不良的缺点，促进物料的溶解，使溶液彻底糊化，便于淀粉酶的作用，以提高浸出物收得率。 关键词：淡爽型；啤酒厂；糊化锅；设计；二次煮出法 Abstract This design for yearly produces 150,000 tons 11°（Shuang-type short ）breweries designs, the saccharification construction sections technological design, is the design key point.The process dextrinize, the saccharification, filters, boils, cooling, uses one sets fermentation process, Uses the cylinder body fermentation pot， the calendar green 14 days fermentation material calculated becomes. This design calculation mainly includes , the thermal graduated arm calculated, coldly consumes the computation and the equipment shaping computation as well as the key equipment gelatinization pot computation. This brewery design blueprint mainly includes the saccharification workshop and the fermentation workshop flow, main equipment gelatinization pot, as well as the glycosylation of the floor plan and elevation drawing workshop. The beer brewed using 70% of high-quality malt, 30% of the rice. In the design uses is the aqueous method smashing, the reason is bec- ause malt skin shell full absoring water changes softly, when smashing the skin shell is not easy to grind, embrionic breast including water mill, evener, the saccharification speed is quick, may enhance the filtration rate. Said to the rice that, the smashing thinner is better, more favor the dextrinize. But the aqueous method smashing exactly can a better thinner smashing. And us- es two time boils the sugar reduction, brews the beer with this method, its co- lor luster light yellow, the froth rich lastingly has the special flavor. Its may recover some malts to dissolve not the good s
