Problems solved by technology

[0003] At present, the mainstream production process of liquid liquor-based liquor is still through cooking the raw materials, which not only consumes energy but also increases the complexity of the process. The cooking process is removed, and the technical problems encountered in the practical application of large-scale industrial production are not considered comprehensively, and the practical guidance is of little significance
[0004] The main disadvantages of the existing liquor-based liquid raw material fermentation process: First, the fermentation scale is basically at the laboratory level, and the fermentation tanks used are basically fully automatic fermentation tanks, which do not consider scaling up to 200-500m 3 The feasibility of the actual production process after even larger fermentation tanks; second, the starch utilization rate of domestic starchy raw materials fermented to produce edible alcohol is ≤90%. Large, high cost, difficult to realize industrialized production; third, there are no relevant literature reports on large tank production examples of enterprises using raw material fermentation to produce liquid liquor base wine
However, this patent uses traditional fully automatic fermentation tanks for fermentation, which is difficult to scale up the process and has poor operability; moreover, the product it prepares is fuel ethanol, which needs to be distilled and dehydrated in the later stage, which consumes a lot of energy
[0006] Chinese invention patent CN 104099376A discloses a method for producing ethanol by using a composite bacteriostatic agent to ferment starchy raw materials: acid protease, amylase, and composite bacteriostatic agents—penicillin and monensin are added to the starch slurry , and adjusted to a pH of 4.0 to 4.5, adding glucoamylase, yeast, and nutrient salts for fermentation; but its disadvantage is that the fermentation needs to adjust the pH to 4.0 to 4.5, and this environment has a certain degree of acid resistance for large-scale fermentation equipment materials Requirements, increase the cost of reagents and equipment materials; and the preparation of starchy slurry in the patented preparation process is too complicated, not suitable for large-scale (200 ~ 500m 3 ) batch production application
