This week, GN Separation is conducting factory testing on two high-speed tubular centrifuges, model GNGQ150, destined for an overseas client's facility. These centrifuges are specifically designed for separating fermentation broths.

Operating at an impressive rotational speed of 14,000 RPM, the GNGQ150 tubular centrifuges generate a separation factor of up to 15,000G, making them highly efficient for solid-liquid separation. This process is crucial in the production of various biopharmaceuticals, enzymes, and other biological products derived from fermentation processes.

The fundamental principle behind tubular centrifuges is centrifugal force, which separates particles based on their density and size. When a mixture is fed into the rotating tube, the centrifugal force pushes heavier particles, typically solids, against the wall of the tube, while lighter particles, such as liquids, remain closer to the center. This results in the separation of components, with the clarified liquid exiting from one outlet and solids being trapped inside the bowl for later disassembly and cleaning.

The versatility and efficiency of high-speed tubular centrifuges like the GNGQ150 make them indispensable in a wide range of industries, particularly those involved in biotechnological processes. Key application areas include:

1. Biopharmaceutical Production: High-speed tubular centrifuges are used to separate cells and cellular debris from fermentation broths, ensuring high-quality products such as vaccines, monoclonal antibodies, and recombinant proteins.
2. Enzyme Purification: Tubular centrifuges gently and effectively purify enzymes from fermentation broths, preserving enzymatic activity and yield, which is crucial for various industrial processes.
3. Microbial Harvesting: In the production of microbial biomass for applications such as biofertilizers and probiotics, high-speed tubular centrifuges offer a rapid and reliable solution for harvesting microbial cells from fermentation mediums.
4. Wastewater Treatment: Tubular centrifuges can separate and concentrate pollutants or valuable by-products in wastewater generated from fermentation processes, facilitating further processing or disposal.
5. Food and Beverage Industry: High-speed tubular centrifuges are employed to clarify and concentrate liquids, remove impurities, and enhance product quality in the production of dairy products, fruit juices, and other food items.

The use of stainless steel 304 for the material contact parts in the GNGQ150 model demonstrates GN Separation Systems' commitment to providing equipment that meets the highest standards of hygiene, durability, and corrosion resistance, which are essential in biological separation applications.

GN Separation remains focused on innovation, quality, and customer satisfaction, continuously pushing the boundaries of separation technology to enable clients worldwide to achieve greater success in their industries.
