Compressed air for fermentation tank

Compressed air requirements for fermenters are as follows:

pressure requirements:

the pressure of compressed air is generally required to be between 0.5-0.7MPa to maintain a stable fermentation process and avoid adverse effects of pressure fluctuations on fermentation. At the same time, it is also proposed that the pressure of compressed air should be controlled between 0.2-0.35MPa. This may vary due to different fermenter designs and usage scenarios, so it needs to be adjusted according to specific conditions in practical applications.

Air quality:

the quality of the compressed air is critical to the fermentation process. After the sterilization treatment, the bacteria content in the compressed air should be reduced to zero or clean air with cleanliness level 100. This can be achieved by an efficient filtration system to ensure that the air entering the fermenter is sterile, thereby avoiding contamination.

Humidity control:

the humidity of the compressed air entering the total filter should be controlled at 60%-70%. Excessive humidity may cause the filter to be damp, thereby affecting the filtering effect. Therefore, the compressed air needs to be dried to maintain a suitable humidity level.

Pretreatment:

before entering the air filter, the compressed air needs to be pre-treated such as water removal and oil removal. This is because the compressed air may entrain water and oil droplets during the compression process, and these impurities can have an adverse effect on the fermentation process. These impurities can be removed by pretreatment to ensure that the air entering the fermenter is clean.

Temperature control:

the temperature of the compressed air will rise during the compression process, so it needs to be cooled. Excessively high temperatures may affect the temperature and microbial activity within the fermenter. The temperature of the compressed air can be reduced to a suitable range through the cooling system to ensure the smooth progress of the fermentation process.

In summary, the compressed air used in the fermentation tank needs to meet certain requirements such as pressure, air quality, humidity, pretreatment and temperature to ensure the stability of the fermentation process and product quality. In practical applications, it is necessary to select appropriate compressed air parameters according to the specific fermenter design and use scenario.
