In August 2025, Greatwall Mixers’ after-sales engineers traveled to Shandong to provide on-site supervision for the installation of agitators in an enzyme preparation project undertaken by a local biotechnology company. The assignment covered equipment positioning, installation precision verification, operational condition calibration, and on-site technical briefings, ensuring the mixing system would operate with high efficiency and stability upon commissioning, laying a solid foundation for the smooth start-up of the project.

About Enzyme Preparations and Their Applications

Enzyme preparations are a class of biocatalysts with high selectivity and catalytic efficiency, mainly derived from microorganisms, plants or animals. It can efficiently catalyze specific chemical reactions under mild conditions, and is widely used in food processing (starch saccharification, lactose hydrolysis, protein modification), feed addition (improving animal digestion and absorption), textile and leather processing (biodegumming, refining), biomedicine (raw material synthesis, drug modification) and environmental treatment (wastewater organic matter degradation) and other fields. With the deepening of the concept of green manufacturing and sustainable development, the industrialization demand for enzyme preparations continues to grow, which puts forward higher requirements for the equipment level of biological fermentation and downstream separation and purification processes.

Greatwall Mixers’ Biotechnological Fermentation Solutions

With decades of expertise in the biotechnological fermentation industry, Greatwall Mixers has developed a comprehensive mixing process and engineering implementation system spanning from R&D and pilot-scale operations to large-scale production. Its product portfolio includes upstream seed expansion fermenters, high-viscosity and non-Newtonian fluid reactors, as well as key downstream equipment for extraction, concentration, and crystallization. Leveraging extensive experience in gas–liquid and solid–liquid mass transfer mechanisms and flow field optimization, the company can precisely configure impeller types, stages, and rotational parameters to suit different microbial metabolic types, fermentation kinetics, and rheological properties. Its designs balance oxygen transfer rate (OTR), mixing time (Tm), shear environment, and energy consumption, achieving optimal oxygen delivery, nutrient distribution, and metabolite removal. This ensures stable and high-yield performance even under high-density cultures, viscous flow conditions, and long-cycle operations.Through deep process understanding and rigorous engineering execution, Greatwall Mixers delivers professional, high-performance fermentation tanks and integrated mixing systems tailored to the specific needs of industries including pharmaceuticals, food, enzyme preparations, amino acids, and more.

The successful delivery of the Shandong project once again demonstrates Greatwall Mixers’ technical expertise and engineering capabilities in the field of biotechnological fermentation mixing. Moving forward, the company will continue to provide industries with professional fermentation mixing systems that combine process compatibility with exceptional performance, helping clients achieve greater efficiency and higher product quality in increasingly competitive markets.
