[0001] The utility model belongs to fermentation equipment technical field, specifically point to a kind of red jujube wine fermentation tank of jujube wine aroma promotion. BACKGROUND
[0002] The aroma of jujube wine is mainly derived from the natural aroma components in jujube fruits, such as esters and alcohols. During fermentation, how to effectively extract and retain these aroma components is the key to improving the aroma of jujube wine. Fermentation temperature, pH value, fermentation time, etc. have a direct impact on the generation of aroma components.
[0003] During fermentation, stirring can maintain the uniformity of the fermentation broth, prevent sedimentation and skinning, and also accelerate microbial metabolism and growth, thereby improving the efficiency of fermentation. Using manual stirring method not only avoids contamination of the wine by manual mixing, but also pays attention to the stirring speed. In addition, the cover should not be opened arbitrarily during fermentation. Sealing helps yeast to ferment under appropriate conditions. However, using mechanical stirring device for stirring, in order to avoid corrosion of liquid to mechanical structure, the stirring device is generally made of stainless steel. However, during fermentation, stainless steel is always in contact with wine. Since the surface in contact with wine is metal, it may subtly affect the taste of wine, including taste, flavor and mouthfeel, etc., which directly affects the aroma. SUMMARY
