Abstract:
Due to the problem of low precision of Baijiu fermentation control caused by the low degree of intelligence of traditional methods, intelligent vision method was adopted to realize the precision control of Baijiu fermentation process from four aspects of fermentation temperature, raw material quantity, fermentation time and pH value of fermentation environment. In order to verify the effectiveness of the technology, a comparative experiment was designed. The traditional control technology was used as the control group, and the control technology based on intelligent vision was used as the experimental group. The results showed that the alcohol content of the experimental group was 95.18%, and that of the control group was 95.26%. The alcohol content of the two groups was similar. However, the ester content of the control group was 0.0046%, the total content of aldehydes and alcohols was 0.0079%. However, the total content of aldehydes and alcohols in the experimental group was 0.0069%, the total content of aldehydes and alcohols in the experimental group was 0.0026%. Due to the high content of ester content of the experimental group and the low content of aldehydes and alcohols, the quality of the Baijiu in the experimental group was better. The overall control accuracy of the experimental group was 90.65%, which was 4.93% higher than that of the control group. The control error rate of the experimental group always fluctuated from 0 to 0, the accuracy rate of temperature control always kept above 95.36%, and the quality scores of Baijiu products were all above 4.73. The results in this work showed that the precision control technology of Baijiu fermentation process based on intelligent vision had good reliability and practicability, which can be popularized in practice.
