Fluid Mixing Technologies

Fermentation is a reaction where organic raw materials converted into products by the action of microbes or enzymes. Agitator plays an vital role to provide mixing and thus increase mass transfer rates.  The mixing action evenly distributes oxygen and nutrients to cells for healthy growth, keeps them from settling to the bottom of the vessel, and helps to maintain a uniform culture temperature.
FMT, provides tailor made solutions of agitators for bioprocessing industries to achieve better MTR/OTR with shear sensitive or insensitive microorganism.

Agitators play a crucial role in bioreactors and bio fermenters, which are vessels used for the cultivation of microorganisms and production of biological products such as vaccines, enzymes, and pharmaceuticals. Agitators in these systems are responsible for providing mixing, aeration, and maintaining uniform conditions throughout the culture medium to optimize microbial growth and product yield. Here are some commonly used agitators for bioreactors and bio fermenters:
Rushton Turbine Agitator: The Rushton turbine is a widely used agitator in bioreactors. It consists of multiple flat blades mounted on a vertical shaft. The rotating turbine generates axial flow and creates a vortex pattern, ensuring efficient mixing and oxygen transfer in the culture medium.
Marine Impeller: The marine impeller is a specialized agitator designed for bioreactors with high-viscosity or non-Newtonian fluids. It has a unique blade design that generates high flow rates, promoting mixing and minimizing shear stress on sensitive microorganisms.
Pitched Blade Impeller: The pitched blade impeller is commonly used in bio fermenters for mixing viscous or non-Newtonian fluids. It consists of blades that are angled with respect to the shaft, creating radial flow patterns and enhancing mixing efficiency.
Magnetic Agitator: Magnetic agitators are often preferred in bioreactors for their advantages of easy cleaning and elimination of contamination risks. They use a magnetic field to rotate a magnetic stir bar placed inside the vessel, providing mixing without the need for a mechanical shaft penetrating the reactor.
Paddle Agitator: Paddle agitators, featuring flat or curved blades, are suitable for gentle mixing in low-viscosity bioreactor applications. They are commonly used during inoculum preparation or when intense mixing is not required.
