In June 2024, Greatwall Mixers' service engineers traveled to Liaoning to provide on-site commissioning services for a bioengineering project. The primary equipment for this batch of agitaors is intended for the production of lactic acid.

      About Lactic Acid

     Lactic acid is an organic acid commonly used as a food additive, serving various functional purposes. Here are some of the main uses of lactic acid in the food industry:

     1.Flavoring agent: Lactic acid can be used to adjust the acidity of food, enhancing its flavor.

     2.Preservative: Lactic acid has antimicrobial properties, which can extend the shelf life of food.

     3.Emulsifier: In some dairy and bakery products, lactic acid can act as an emulsifier, helping to blend different components.

      4.pH regulator: Lactic acid can regulate the pH of food, maintaining the stability and quality of the product.

      5.Fermenting agent: Lactic acid is an important component of many fermented foods (such as yogurt, sauerkraut), aiding in the fermentation process. The wide application of lactic acid in the food industry is widely recognized for its safety.

      Design Selection

      For this project, we conducted in-depth analysis of the customer's process requirements, site conditions, material characteristics, and parameters, and tailored an efficient mixing solution. The design incorporates a defoaming impeller, a three-blade axial flow impeller, and a combination of a four-blade half-pipe and parabolic disk turbine impellers.

      FThis combination of impellers not only has strong defoaming capabilities but also achieves high turbulent diffusion capabilities and high shear forces, suitable for application in fermenter mixing tanks. Its efficient mixing performance significantly improves the outflow of the transitional flow and turbulent flow zones by 20% compared to traditional propeller agitators, particularly suitable for operations with low viscosity liquids, such as mixing, dissolution, solid suspension, and key heat transfer processes in bioreactors.

      The core advantage of this technology lies in its gas handling capabilities. The bottom-mounted four-blade half-pipe and parabolic disk turbine impellers have extremely high radial displacement and dispersion capabilities, making the mass transfer coefficient higher than other types of agitators under the same power, and the gas-holding capacity stronger, which is particularly important for bioreactors that require a large amount of oxygen transfer. Furthermore, this optimized structure ensures that the equipment is easy to clean and maintain, adaptable to changing production conditions, greatly improving the flexibility and convenience of operation. In terms of energy saving and consumption reduction, this agitator combination performs excellently, as its efficient mixing and mass transfer performance effectively reduce energy consumption, reducing operating costs for enterprises. At the same time, the good mixing effect is conducive to improving the quality of the final product, especially in the field of biotechnology, where it can significantly increase the yield and quality of products, thereby enhancing the market competitiveness of enterprises.

      Environmental friendliness is also a highlight of this technology. By optimizing the mixing process, energy consumption and raw material consumption are reduced, lowering the environmental impact during production, which aligns with the current trend of sustainable development.

      Greatwall Mixers' after-sales engineers closely supervised the assembly, commissioning, and testing process of the agitator on-site, promptly resolving technical problems encountered during installation. Their professional guidance ensured that the agitator combination was installed correctly according to standards. Additionally, through training of operators, the proficiency of users in operating the equipment was enhanced, ensuring the stable operation of the equipment.

      The successful cooperation of this project provides a new example for technological progress in the field of biotechnology. This agitator combination technology, particularly its application in lactic acid production processes, demonstrates its significant effects in increasing production, saving energy, and improving product quality. As the global demand for sustainable production methods continues to grow, Greatwall Mixers' professional capabilities and deep understanding of customer needs will ensure its continued key role in future industrial development. The company will continue to focus on providing more efficient and environmentally friendly solutions to various industries through technological innovation and quality customer service, jointly opening a new chapter in production technology.
