Application Background and Needs of Fermentation Tanks

Fermentation tanks play a vital role in industrial production, utilized in both experimental and factory-scale environments. During the production process, these tanks require continuous addition and supplementation of various trace elements or catalysts to control fermentation properties. The precision of these added trace elements significantly impacts the fermentation process's progress and the final product's quality.

Typically, fermentation processes rely on various pumps to automatically and continuously add liquids. Throughout the fermentation cycle, pumps must supply acids, defoamers, and media continuously and stably. Key requirements for these pumps include:

• Sealed and Pollution-Free Conveying: The entire process must avoid contamination.
• Simple Maintenance: Maintenance should be straightforward.
• Low Shear Force: Essential to avoid damaging sensitive cells and substances.
• Constant Flow: The flow must remain consistent throughout.
• Adjustable Flow Rates: The flow rate needs to be adjustable from 0.1 ml/min to 300 ml/min.
• Real-Time Monitoring: Continuous monitoring of fermentation states is necessary to prevent cell activity loss during cultivation.
• Mechanical Cooperation: The pump should easily integrate with the tank control cabinet, often in an embedded OEM form.

Due to these needs, peristaltic pumps are often chosen for applications like acid supplementation, alkali supplementation, defoaming, and fluid supplementation in biological fermentation.

 

Why Choose a Peristaltic Pump in Biological Fermentation and Its Advantages

Peristaltic pumps transmit liquid by squeezing a hose, ensuring that the liquid only contacts the hose. This design provides several advantages:

• Sterility: The entire pipeline remains sealed, meeting sterility requirements.
• Low Shear Force: This feature is suitable for sensitive cells and drugs, preventing damage to the liquid.
• Ease of Use and Maintenance: Maintenance involves simply replacing the hose, while other pump types contact the pump cavity, complicating cleaning and maintenance.
• Manufacturability: Peristaltic pumps can be embedded according to customer needs, allowing high compatibility with control cabinets.
• Servo Control System: Equipped with a servo system, these pumps offer better stability than traditional stepping motors or DC gear motors, enabling real-time monitoring and remote control via PLC. This integration allows customers to understand the real-time status of the fermentation process.

The servo motor's characteristics—high torque, closed-loop control, and low-speed stable operation—meet diverse customer needs across different tank volumes.

 

How to Choose a Biological Fermentation Peristaltic Pump

1. Easy Maintenance: The pump structure should allow easy opening and closing for hose installation and removal, facilitating maintenance.
2. High Flow Repeatability: It should operate continuously and stably, with adjustable speed, a wide flow range, high torque, and low-speed operation, controlled via a servo system.
3. Embedded Installation: The pump should be designed for OEM installation, allowing direct integration with the customer's control cabinet for linkage control.
4. Feedback and Temperature Detection: Incorporating these features can address concerns about overheating and out-of-step issues.
5. Remote Control Compatibility: The pump should support various remote control methods (4-20mA, 0-5V, Modbus 485 communication) to adapt to the customer's integrated system, facilitating equipment control integration.

 

Conclusion

Ideal Solution: Peristaltic pumps are the preferred choice for biological fermentation due to their advantages in maintaining sterility, ease of maintenance, and compatibility with advanced control systems.
