“超酒”酵母在孟州华兴酒精厂的应用试验

Trial Application of High Temperature Resistant Super Active Dry Yeast (HY) in Huaxing Distilling Plant

以玉米为原料,采用安琪耐高温超级酿酒高活性干酵母进行酒精浓醪发酵大罐试验,发酵温度控制在34±1℃,发酵时间60h左右,前6～7h缓慢进料。结果表明,超级耐高温酿酒高活性干酵母繁殖速度快,耗糖快,能显著缩短发酵时间,提高出酒率。在发酵过程中,应根据罐内醪的浓度和温度,控制好进醪量、进醪温度和冷却水,使发酵罐内温度稳定。

The experiment of high concentration mash fermentation in big pots by high temperature resistant super active dry yeast(HY) with corn as raw materials was done. Fermentation temperature was controlled at 34±1 ℃ and fermentation time was about 60 h. Slow raw materials charging operated in the prior 6～7 h. The experimental results suggested that the application of HY could shorten fermentation time obviously and increase liquor output rate because of its rapid reproduction and fast sugar consumption. During the process of fermentation, in order to keep stable temperature in fermenting pots, mash charging quantity, charging temperature, cooling water should be under proper control according to mash concentration and temperature in pots.
