Problems solved by technology

With the continuous advancement of science and technology and people's living standards, the production process of liquor is also developing rapidly with the large-scale and refined mechanical equipment and testing tools. However, in the process, in the production process of liquor, experience The part occupied is still too much, and some classification and quality inspections only rely on people to observe with the naked eye, and then determine the next step of work based on experience, which seriously limits the development of liquor production technology
For example, the quality of various original liquors in the liquor distillation process and the various classifications in the liquor blending process are all based on experience alone, and the uncertainty of experience will seriously affect the accuracy of liquor production , which will have a serious impact on the quality and high-quality rate of finished liquor
[0003] Electronic nose, an artificial intelligence odor recognition system, judges the composition of the gas by analyzing the absorbed gas. The current electronic nose technology is based on the principle of gas chromatography. It detects quickly and has a wide range of analysis and detection. For application to the field of liquor brewing
