It was introduced to you in the previous article《 Why use a nitrogen machine in a brewery？》This article Xiaobian collection collatedThe role of compressed air in the beer industryWhat do you have？The details are as follows:

The role of compressed air in the beer industry, bottling/canning

Compressed air is used to transport the beer from the regulating canister to the bottle and to keep the lines clean。Class 0 oil-free air will ensure that lines and fuel tanks are not contaminated in the process。

The role of compressed air in the beer industry two, clean air

Oil-free compressed air is used to clean bottles and packaging before filling。If the air is polluted, in addition to being a health hazard, it can change the taste, smell and foam。

The role of compressed air in the beer industry three, fermentation

During the fermentation process (aeration), compressed air provides oxygen to bacteria。 This uses microorganisms to convert hydrocarbons into alcohol。 During this process, it is important to provide the exact amount of compressed air and maintain the correct oxygen level to determine the quality of the yeast。

Fermentation in the brewing process阶段

Ethanol fermentation or alcohol fermentation is a very important part of the brewing process, during which the beer will acquire its alcohol content。Brewing and fermentation stage is one of the last stages of brewing beer.It occurs after grinding, saccharification, filtration, boiling, cycloprecipitation, and cycloprecipitation。

At this stage, the liquid-filled tank is filled with oxygen。It is important to maintain a moderate aeration rate (i.e. moderate oxygen content) so as not to destroy the yeast。The amount of oxygen required depends on the amount of liquid and bacteria in the tank。The yeast then converts the glucose in the wort into ethanol and releases carbon dioxide gas (CO2)。This carbon dioxide can then be recovered。

The role of compressed air in the beer industry four, packaging/labeling

In packaging, labeling and other processes, compressed air is used to control valves and actuators in automation lines。Oil-free air prevents automation components from getting stuck, reducing maintenance costs。

The role of compressed air in the beer industry five, sewage treatment

The water used in the boiling process must be treated before it can be returned to the water cycle to minimize environmental impact。 Of course, the air needed for this treatment must be oil-free, otherwise the water will become contaminated again。

The role of compressed air in the beer industry six, carbon dioxide recovery

The carbon dioxide produced during the fermentation process can be recovered, used to carbonate your goods, or by storing the carbon dioxide and then selling it。

In the production of beer, the brewery needs to carry out a complete set of malting, milling, beating and other processes。

One of the steps is yeast fermentation。In this process, a low-pressure compressor provides oxygen to the yeast, which in turn uses the microbes to produce alcohol。In the process, carbon dioxide is produced and released。

Our CO2 recovery system can recover CO2 and store it, which would otherwise be lost。We know that beer produces about 4kg per hectolitre The same amount of beer requires only 3kg of dissolved carbonate This suggests that the brewery will not only be able to sustain its own demand for carbon dioxide, but will also be able to use the extra carbon dioxide for other businesses目的。
