摘要
通过对酒精发酵蒸煮过程的计算,分析了降低蒸煮环节能耗的几种办法。结果表明,加水比由3.4降低到2.2,节约蒸汽约31.2%,醪液量减少约34.1%,提高生产能力30%以上;生熟料换热温度从50℃提高到90℃,节约蒸汽约78%;滤液回用,减少排糟液量;喷射液化,减少蒸汽的消耗量。
Several energy-saving and emission reduction methods during the cooking and steaming of alcohol high-gravity mash fermentation were analyzed in this study through scientific calculation. The results suggested that it could save 31.2 % steam and reduce 34.1% mash use quan- tity and improve productivity by above 30 % as water addition ratio reduced from 3.4 to 2.2, it could save about 78 % steam as heat transfer tem- perature of uncooked raw materials and clinker rose from 50 ℃ to 90 ℃, the recycle use of filtering liquid could reduce the emission quantity, and spraying liquefaction could reduce the consumption of steam. （Tran. by YUE Yang）
