Monitoring Application of Carbon Dioxide Sensor in Liquor Fermentation

Liquor fermentation refers to the fermentation process, which requires sugar and enzymes. Liquor, as a kind of distilled wine, is made from starch or sugar through fermentation or distillation. Fermentation is an essential step in the preparation of baijiu. Sugars include glucose and maltose. Juice usually contains a lot of glucose and can be directly fermented. Cereals contain a lot of starch, which can be processed to produce maltose.

Liquor fermentation refers to the fermentation process, which requires sugar and enzymes. Liquor, as a kind of distilled wine, is made from starch or sugar through fermentation or distillation. Fermentation is an essential step in the preparation of baijiu. Sugars include glucose and maltose. Juice usually contains a lot of glucose and can be directly fermented. Cereals contain a lot of starch, which can be processed to produce maltose.

Sugar reacts chemically with enzymes at a certain temperature to produce ethanol and carbon dioxide. This reaction process is called alcoholic fermentation. Alcoholic fermentation can be carried out without oxygen and can produce 51 grams of alcohol per 100 grams of sugar. There are many methods of alcoholic fermentation, but most of them are carried out in special containers, such as tanks, altars, barrels, etc.

There are many chemical reactions in the process of alcoholic fermentation, and carbon dioxide (CO2) is the main chemical product in the process of alcoholic fermentation. With the continuous fermentation of alcohol, the content of carbon dioxide gas in the fermentation device is constantly increasing. When the carbon dioxide gas content is too high, the activity of the enzyme will be reduced, directly affecting the stability of the fermentation. Moreover, in alcohol fermentation, most of the fermented enzymes are anaerobic bacteria, and alcohol fermentation is completed through anaerobic respiration.

In addition, as the CO2 content continues to increase, so does the gas pressure in the fermentation unit. When the gas pressure reaches a fixed value, it is easy to cause excessive pressure in the fermentation device, and then the sealing device becomes loose, which directly affects the sealing effect and destroys the fermentation quality.

In addition, carbon dioxide is a by-product of the wine fermentation process. Because the density of carbon dioxide is heavier than that of air, it is easy to overflow from the fermentation tank, and when it falls on the ground of the brewery, it will form fatal and imperceptible potholes, which will bring great hidden dangers to the safety of operators. The workers in charge of the fermentation tanks are also at risk, as residual carbon dioxide gas can reduce the oxygen in the tanks to lethally low levels.

Therefore, during the liquor fermentation process, carbon dioxide concentration monitoring is very necessary, and a CO2 gas sensor can be used for monitoring.

How to choose a suitable carbon dioxide gas sensor is very important. At present, most common carbon dioxide gas sensors use the principle of non-dispersive infrared (NDIR). The basic principle is the quantitative analysis by measuring the change of the selective absorption intensity of the detected gas CO2 to the electromagnetic radiation in the infrared region. When using this type of sensor, care needs to be taken to adopt a carbon dioxide gas sensor that can automatically maintain stable and reliable measurement accuracy and performance at all times. For example, the MH-Z19C carbon dioxide gas sensor of Winsen Technology is a high-performance infrared gas sensor made of this principle.
