1000m³ Super Large-Scale Glutamic Acid Fermentation Project

As the bio-fermentation industry rapidly advances towards larger scale and higher efficiency, 1000m³ fermenters are becoming the new industry benchmark. However, this increased scale also introduces core challenges such as mixing homogeneity and energy consumption control. As a solution provider pushing the boundaries of fermentation technology, MIXEL leverages over 55 years of agitation design expertise to successfully empower facility owners in achieving energy-efficient glutamic acid production within these ultra-large 1000m³ vessels. Verified results demonstrate nearly 20% energy savings, driving the next wave of technological innovation in the industry.

Fluid Flow Design Challenges in Large Fermenters

After fermentation tank capacity exceeds 600m³, traditional stirring configurations face three major bottlenecks：

01.  Mixing inhomogeneity

Non-uniform gas-phase dispersion, inadequate oxygen transfer, and pronounced tendency for solid-liquid phase separation

02.  Surge in energy consumption

Imbalance between impeller diameter (d/D ratio) and rotational speed ; 

03.  Performance variability

Significant differences exist in gas dispersion and mass transfer performance between different manufacturers under the same operating parameters.

MIXEL Solution

Independently designed for each tank, impeller spacing, diameter, and rotation speed combinations are precisely verified through CFD fluid simulation, achieving power prediction accuracy exceeding 97%.The patented impeller system balances high discharge capacity with low energy consumption, completely overcoming mixing bottlenecks in large tanks.
