Design of real-time temperature monitoring system in liquor brewing process

In comparison to internationally renowned liquors, Chinas fen-flavor liquor is characterized by its milder taste and healthier properties. However, with the advancement of intelligent brewing technologies, the quality of foreign liquors has significantly improved, increasingly challenging the market position of Chinese liquors. This study begins with an overview of the liquor brewing process, emphasizing the critical role of temperature control in fermentation. Subsequently, we propose an innovative real-time temperature monitoring system specifically designed for liquor production. The system incorporates a precisely engineered temperature sensor, complemented by a robust data transmission framework and an efficient storage module for real-time temperature visualization. To validate the systems effectiveness, field tests were conducted at a distillery in Xinghua Village, focusing on real-time temperature measurement of brewing materials. The experimental results demonstrate that our system successfully achieves real-time monitoring of temperature variations during both the cylinder fermentation and material processing stages of liquor production. Compared with traditional methods relying on manual sensory evaluation and empirical judgment, this system enables more precise control over raw material proportions, thereby enhancing both the flavor profile and production yield of fen-flavor liquor. This technological advancement represents a significant step toward the intelligent transformation of traditional Chinese liquor-making techniques.
