浅谈米香型白酒生产工艺中的节能降耗

Energy-saving during rice-flavor Chinese liquor production

为进一步改善米香型白酒清洁生产、节能、低排放,依托米香型白酒酿造机械化新工艺平台,对供热与水资源循环进行了设计和研究。结果显示,实施机械化新工艺后,米香型白酒单位耗水量由原来的54 t/k L下降到30 t/k L左右,降幅达到45%;单位耗煤量由0. 85 t/k L下降到0. 55 t/k L左右,降幅达到35%;并且在出酒率提升,酒质改善的同时,人工劳动成本下降60%～70%。新工艺与传统工艺相比,具有良好的换热效果,大大缩短蒸馏时间,并且冷却水循环再利用也得到了实现,即可满足生产,又可达到节能目的。

In order to improve the cleaner production of rice-flavor Chinese liquor and to make the process energy-saving with low emission, this paper designed and studied the heating and water resources cycle based on the new mechanized brewing technology produces rice-flavor Chinese liquor. The results showed that after implementing the new mechanized process, the water consumption per unit of liquor decreased by 45% from 54 t/KL to 30 t/KL. The unit coal consumption decreased by 35% from 0.85 t/KL to 0.55 t/KL. Moreover, the labor cost reduced by 60%-70% while the yield of alcohol and liquor quality improved. Compared with the traditional strategy, the new strategy had a good heat exchange effect, which greatly shortened the distillation time. Besides, recycling cooling water was also realized, which not only achieved the desired effect but also saved resources.
