In modern biotechnology and food industry, fermentation tanks play a crucial role. As a core equipment for microbial cultivation and chemical reactions, fermentation tanks not only promote progress in various fields such as biomedicine, brewing, and biofuels, but also profoundly affect every aspect of daily life. Jinzong Enterprise, with over 20 years of experience in fermentation tank production design and research and development, will take you in depth to explore the structural design, functional characteristics, working principles, and wide application scenarios of fermentation tanks, unveiling the mystery of this key equipment for you.
一、Structure Design of Fermentation Tank
The main body of the fermentation tank is usually made of stainless steel material to ensure good corrosion resistance and cleanliness. Its basic structure includes tank body, mixing system, ventilation and exhaust device, temperature control system, sensors and controllers, etc.
Tank Body：It is the main container for the fermentation process, which can range from tens of liters to hundreds of thousands of liters depending on its capacity. It is designed with an insulation layer to maintain a constant fermentation temperature.
Mixing System：Composed of an electric motor driven agitator and a stirring paddle, it is used to mix culture medium and microorganisms, increase dissolved oxygen, and promote uniform distribution of microorganisms.
Ventilation and Exhaust Device：Provide oxygen to microorganisms while eliminating metabolic products such as carbon dioxide to maintain a stable gas environment.
Temperature Control System：Adjust the temperature inside the tank through electric heating sleeves, cooling coils, and other equipment to accurately control the fermentation conditions.
Sensors and Controllers：Monitor and regulate parameters such as pressure, pH value, and dissolved oxygen concentration inside the tank to achieve automated management of the fermentation process.
二、Function Features
Efficient Microbial Cultivation: By optimizing stirring and aeration design, the growth rate and product yield of microorganisms are improved.
Accurate Environmental Control: The automated control system can accurately adjust parameters such as temperature, pH value, dissolved oxygen, etc., ensuring the stability and efficiency of the fermentation process.
Repeatability and Scalability: Standardized design makes experimental results easy to replicate, and fermentation tanks of different sizes can meet the needs from small-scale trials to large-scale production.
Easy to Clean and Disinfect: Stainless steel material and fine sealing design facilitate CIP (in place cleaning) and SIP (in place sterilization), ensuring production safety.
三、Working Principle
The work of the fermentation tank is based on the biological transformation of microorganisms. In a suitable culture medium, microorganisms utilize oxygen for respiration, consume nutrients, and produce target products.During the fermentation process, the stirring system promotes the flow of the medium, increases the amount of dissolved oxygen, and avoids hypoxia caused by excessive aggregation of local microorganisms. The ventilation device replenishes oxygen, while the exhaust eliminates the generated carbon dioxide and other volatile substances. The precise control of parameters such as temperature and pH ensures the optimal growth conditions for microorganisms, thereby maximizing product output.
四、Widespread Application
Biopharmaceuticals: producing antibiotics, vaccines, biological enzymes, monoclonal antibodies, etc.
Food Industry: brewing beer, alcoholic beverages, yogurt, yeast extracts, etc.
Chemical Industry: preparing chemical products such as amino acids, organic acids, and biofuels.
Agriculture: producing microbial fertilizers, biopesticides, etc. to promote the development of ecological agriculture.
In summary, as an important tool in the field of biotechnology, fermentation tanks are supported by advanced design and control technologies for the development of numerous industries, and are a key bridge connecting basic scientific research and industrial production. With the continuous advancement of technology, future fermentation tanks will become more intelligent and efficient, creating more value for human society.
