Description

TECHNICAL FIELD

[0001] The utility model relates to wine detection equipment technical field especially relates to a high temperature Daqu wine variable control device. BACKGROUND

[0002] As one of the four basic liquor flavors in China, Jiangxiang liquor has been favored by domestic and foreign consumers, and is one of the most prominent flags in the world. After more than a hundred years of development, Jiangxiang liquor has formed a unique "12987" brewing process, creating a unique style characterized by prominent sauce aroma, elegant and delicate, long-lasting aroma in an empty cup, soft and mellow entry, and long aftertaste. The characteristics of Jiangxiang liquor brewing process can be condensed into "four high and two long", "four high" refers to "high temperature koji making, high temperature stacking, high temperature fermentation, high temperature distillation", among which "high temperature stacking" is one of the most important processes that distinguish Jiangxiang liquor from other flavors. The main reason for high temperature stacking of Jiangxiang liquor is that high temperature or super high temperature Daqu inhibits or kills most of the heat-intolerant and high-saccharifying enzyme and alcohol-producing enzyme microbial flora during koji making, resulting in low content of yeast and mold in the koji, weak saccharification and fermentation activity of the koji, and inability to successfully complete the fermentation and aroma production of the fermented grains after entering the cellar. The fermented grains will continuously adsorb and enrich the brewing microbial flora in the environment during high temperature stacking, and complete starch saccharification, protein degradation and aroma substance and precursor generation in the fermented grains. According to production experience, the top temperature of the fermented grains can reach about 45-55℃ after about 5d of stacking saccharification, at which time the microorganisms in the fermented grains proliferate and metabolize vigorously, generating a large amount of aroma substances. About a thousand aroma substances have been found in the wine body during the stacking saccharification process. The industry summarizes "high temperature stacking" as "secondary koji making", and "no stacking, no Jiangxiang" is consistent with the research results that Jiangxiang liquor cannot be produced without adding Daqu and stacking saccharification.
