The dissolved oxygen function on the fermentation tank refers to the function of controlling and monitoring the oxygen (O2) content in the fermentation liquid during the fermentation process.
The dissolved oxygen function usually consists of a dissolved oxygen sensor and a corresponding monitoring system, which is used to monitor the oxygen concentration in the fermentation broth in real time and adjust it as needed.
The following are some of the main functions and characteristics of the dissolved oxygen function on fermenters:
1. Oxygen monitoring: The dissolved oxygen sensor can monitor the oxygen content in the fermentation broth in real time and provide quantitative data on the dissolved oxygen concentration. This aids in the control and optimization of the fermentation process.
2. Fermentation control: Oxygen is one of the key factors in many microbial fermentation processes. By monitoring and controlling the oxygen content in the fermentation broth, the growth and metabolic processes of microorganisms can be optimized, and the yield and quality of fermentation products can be improved.
3. Dissolved oxygen adjustment: Based on real-time monitored dissolved oxygen data, the control system on the fermentation tank can automatically or manually adjust the dissolved oxygen level to meet specific fermentation needs. This may involve injecting oxygen into the fermenter or by adjusting the stirring speed, for example.
4. Abnormal alarm: If the oxygen content in the fermentation broth exceeds the preset range or changes abnormally, the monitoring system can issue an alarm to remind the operator to take appropriate measures to prevent abnormalities or failures in the fermentation process.
The dissolved oxygen function on the fermenter is usually controlled by:
1. Gas control system: Fermentation tanks are usually equipped with a gas supply system, which can inject oxygen or other gases into the fermentation tank to adjust the oxygen content in the fermentation liquid. This system usually consists of a gas regulating valve, a gas flow meter and a gas delivery pipeline.
2. Stirring system: Fermentation tanks are usually equipped with a stirring system, which can control the distribution and dissolution of oxygen in the fermentation liquid by adjusting the stirring speed and method. Stirring can help better mixing and contact between gas and liquid, thereby promoting the dissolution and dispersion of oxygen.
3. Dissolved oxygen sensor: A dissolved oxygen sensor is installed on the fermentation tank to monitor the dissolved oxygen content in the fermentation broth in real time. The sensor transmits dissolved oxygen data to the control system, which regulates gas supply and stirring operations as needed to maintain appropriate dissolved oxygen levels.
4. Control algorithm: The control system is usually equipped with a corresponding control algorithm to automatically adjust gas supply and stirring operations based on real-time monitored dissolved oxygen data and preset target values. This enables precise control and regulation of dissolved oxygen levels to meet the needs of different fermentation processes.
5. Manual intervention: In some cases, operators may need to perform manual intervention based on actual conditions, such as adjusting parameters of gas supply and stirring operations to deal with abnormal conditions or special needs during the fermentation process.
Through the above control method, the dissolved oxygen function on the fermentation tank can achieve precise control and regulation of the dissolved oxygen level during the fermentation process, thereby improving the efficiency, stability and yield of fermentation production.
Through the dissolved oxygen function on the fermentation tank, precise control and monitoring of the fermentation process can be achieved, thereby improving the efficiency, stability and yield of fermentation production. This is of great significance for fermentation production processes in biopharmaceuticals, food industry, bioenergy and other fields.
