BR500ALB Series Airlift Fermenter & Bioreactor
BR500ALB series airlift fermenter & bioreactor is a gas-liquid bioreactor based on the principle of ventilation pipes, without any mechanical stirring. Compressed air is used for aeration and agitation. The turbulence caused by the gas/fluid flow ensures adequate mixing of the liquid. The gas used for agitation can act to either, introduce new molecules to the mixture inside of the bioreactor, or remove specific metabolic molecules produced by microorganisms.
Key Facts
-
Efficient gas-liquid dispersion with low power consumption
-
Low shear rate (have homogeneous shear and stress forces throughout the entire bioreactor.)
-
Improved fluidization characteristics
-
Excellent liquid-solid and gas-liquid mass transfer
Características
15-Inch Touch Screen
Provides a user-friendly interface for simplified control and real-time monitoring of the bioreaction process.
Special Stirring System
Utilizes an airlift principle for stirring, reducing energy consumption and contamination risk while achieving high mass transfer efficiency with minimal shear force.
Efficient Air Sterile Regulation
An external air compressor and sterilization system ensure sterile conditions for optimal microbial or cell growth.
Fully Automatic Sterilization in Place
Uses external steam for sterilization in place, reducing manual operations and contamination risks.
Stable and Reliable Hardware
Features high-quality components like Siemens PLC controllers and Swiss Hamilton electrodes for precision and durability.
Intelligent PID Control
Manages heating, cooling, pH, dissolved oxygen (DO), foam, and tank pressure to maintain optimal process conditions.
Structure
Airlift Bioreactor Diagram
An airlift bioreactor works by stirring cultured substance using gas. Air/Gas is fed through a sparger ring into the bottom of a concentric tube, which directs the circulation of both air bubbles and liquid. At the top of the bioreactor, there is a gas separator to remove gaseous substances.
Air bubbles flow upwards within the central draft tube; some of these bubbles coalesce at the top of the column and exit, while others follow the degassed liquid and circulate downward from the area outside the draft tube.
