入池糟醅含氧量对发酵的影响

入池糟醅含氧量对糟醅发酵很重要，其氧含量主要受踩池松紧和辅料谷壳的添加量影响。通过5轮实验研究表明：添加20％的辅料谷壳和进行100％的踩池较适宜，可提高白酒产量3％～5％，提高酒质2％～5％；无论冬、夏，都可100％踩池，糟醅水分中所溶解的氧，足够酵母繁殖所需。

Effects of Oxygen Content in Fermenting Grains for Pit Entry on the Fermentation

The oxygen content in fermenting grains for pit entry played an important role in the fermentation of fermenting grains . The oxygen content was mainly influenced by pits-stepping degree and the addition level of chaff. The best conditions were summed up as follows through the experiments for five times: addition of 20 % chaff and 100 % pits-stepping which could increase liquor yield and quality liquor yield by 3 %-5 % and 2 %-5 % respectively; 100 % pits-stepping done whatever in summer and in winter, and the oxygen dissolved in the water of fermented grains was enough for yeast reproduction.
