What Is The Significance Of Stirred-Tank Bioreactor?

There are various forms of bioreactors, and the stirred tank bioreactor (STB) is undoubtedly one of the most classic and commonly used biofermentation equipment. Whether in drug production, food fermentation, or in environmental protection and bioenergy production, stirred tank bioreactors play a key role. They provide a uniform and controllable environment for the bioreaction process, which helps to improve the quality and production efficiency of the product.

The stirred tank bioreactor is an ideal external environment for controlling the rapid metabolic growth of organisms by stirring various substances (carbon source and nitrogen source nutrient base, trace elements and various cultured organisms, etc.) in a closed container, so that they are evenly distributed. At the same time, it is equipped with a temperature control system, a pH adjustment system, a gas adjustment system, a defoaming system, etc. to control the rapid metabolic growth of organisms, thereby maximizing the production efficiency and quality of organisms. Very suitable for biological reactions of liquid materials.

Compared with other types of bioreactors, stirred tank bioreactors have the following advantages:

1. Easy operation: The stirred tank bioreactor uses strong stirring, which makes the operation more convenient.

2. Improve the reaction effect: The stirred tank bioreactor can increase the contact area between the organism and the nutrient medium and accelerate the reaction speed.

3. Strong adaptability: The stirred tank bioreactor can adapt to the cultivation and production of different organisms.

4. High efficiency and energy saving: The stirred tank bioreactor adopts stirring to react, improve production efficiency and save energy.

5. High degree of automation: Through various software and sensor control, it makes the fully automated operation, high precision, less human error, and ensures the stability of product quality.

1. Provide a uniform reaction environment

Distribution uniformity is an important factor affecting the biological reaction rate and product output. The stirred tank bioreactor uses mechanical stirring to mix various reaction substances and organisms in the reaction system evenly, ensuring that the organism can get sufficient nutrition and oxygen supply, so as to maximize the growth and metabolic efficiency and quality.

2. Improve mass transfer efficiency

During the stirring process, the stirred tank bioreactor increases the contact area between gas and liquid, increases the solubility of gas, especially the solubility of oxygen, and accelerates the metabolism of aerobic organisms. At the same time, it makes the mass transfer efficiency of other carbon sources, nitrogen sources and metabolites higher.

3. Precise control of bioreaction conditions

The automatic control system equipped with the stirred tank bioreactor can monitor these key parameters (such as pH, temperature, dissolved oxygen concentration, defoaming, carbon source, nitrogen source concentration, etc.) in real time to ensure that the reaction conditions are always maintained at the optimal state. After the high-precision sensor usually detects the difference between the set value and the detection value, the PLC control system will automatically control the feed pump of the corresponding condition to feed or inlet, and then quickly adjust to the set value with the help of the stirring system.

4. Wide range of applications

The design of the stirred tank bioreactor is flexible and can easily adapt to the production needs of different industries. It plays an irreplaceable role in many fields such as fermentation process, pharmaceutical, food processing, bioenergy and environmental protection treatment. The reaction tank agitator can provide strong support for the production process with its efficient stirring capacity and precise temperature control system.

5. Easy to scale up production

The stirred tank bioreactor can be easily scaled up from small-scale laboratory reactions to industrial production scale. This flexibility enables new technologies to be quickly replicated from research and development to large-scale batch production, which can ensure the stability and repeatability of the process and reduce the difference between experimental scale and industrial production. Thus, the benefits of R&D technology in commercial promotion are maximized.

6. Easy to automate

The stirred tank bioreactor can be customized with fully automated control. Equipped with online sensors and control software systems, the reactor can monitor various parameters in the reaction process in real time and automatically adjust and optimize the reaction conditions. This automation not only improves production efficiency, but also reduces errors in human operation and ensures the stability of product quality.

1. Production of pharmaceutical preparations

Stirred tank bioreactor are widely used in the production of biopharmaceutical preparations, such as antibodies, vaccines, hormones, etc. By rationally designing the reactor structure and controlling the culture conditions, high-yield and high-purity biological products can be achieved.

2. Food fermentation

The fermentation process in the food industry (such as brewing, soy sauce, dairy products, etc.) is also inseparable from the stirred tank bioreactor. By optimizing the reaction conditions in the reactor, not only the fermentation rate can be increased, but also the flavor, taste and nutritional content of the product can be controlled.

3. Bioenergy production

In the process of bioenergy production (such as bioethanol, biogas, etc.), it can be used for the biodegradation and conversion of biomass, such as bioethanol, biodiesel, etc. By optimizing the stirring and oxygenation mechanism of the reactor, the reaction efficiency and product yield can be improved.

4. Environmental protection

Stirred tank bioreactors are also widely used in the field of environmental protection. Microorganisms can use organic matter in wastewater for metabolic activities, convert harmful substances in wastewater into harmless substances, thereby purifying wastewater.

Stirred tank bioreactors undoubtedly play an important role in the development and progress of biotechnology. With the process of intelligent technology, bioreactors will continue to upgrade and play a greater value.
