3. Application of gas mass flowmeter in oxygen supply control during beer brewing
Gas mass flowmeter is the core tool for oxygen supply control in beer brewing by accurately controlling oxygen supply, optimizing yeast growth environment, and improving beer quality and production efficiency.. The specific applications are as follows: Application background and core requirements. In beer brewing, oxygen is a key factor for yeast reproduction and fermentation. Yeast requires an appropriate amount of oxygen for aerobic respiration during the early stages of fermentation to rapidly proliferate and form a healthy microbial community; In the subsequent fermentation stage, it is necessary to switch to an anaerobic environment to convert glucose into alcohol and carbon dioxide.
