When it comes to clarifying liquids with low solid content or separating fine particles, tubular centrifuges offer a practical and reliable solution. At GN Separation, the high-speed tubular centrifuge is designed to provide consistent performance for applications in a range of industries, including food and beverage, chemical processing, and biotechnology.

 

Key Operating Principles

GN’s high-speed tubular centrifuge is a vertical type separation unit that operates at speeds up to 15,000 RPM, generating a centrifugal force of up to 16,000×g. The tubular bowl, which rotates at high speed, creates a strong centrifugal field that pushes solid particles outward to the inner wall of the bowl, while the clarified liquid flows through the center and exits from the top.

Because the solids remain attached to the inner wall of the bowl, the machine requires a shutdown and manual cleaning after each operation cycle. Despite this, the unit offers a straightforward mechanical structure and user-friendly maintenance routine, making it well-suited for batch operations with relatively low solid content (typically below 1%).

Practical Applications

The GN tubular centrifuge is commonly used in:

• Plant and herbal extraction processes, for clarifying mixtures such as plant oils, pigment suspensions, and natural extracts.

• Biotechnology and pharmaceutical production, where it helps separate microbial cells, yeast, proteins, or other biological solids from fermentation broth or nutrient liquids.

• Food and beverage industry, for purifying beverages or separating impurities from essential oils and flavor concentrates.

• Fine chemical processing, where precise clarification is required.

Features and Design

The machine is made from corrosion-resistant materials such as stainless steel to ensure cleanliness and durability. Safety mechanisms including vibration protection and overload protection are incorporated to maintain stable operation. The compact vertical design allows for space-efficient installation, while the solid-liquid separation is performed without the need for complex filters or additional consumables.

Summary

GN Separation’s high-speed tubular centrifuge offers a dependable choice for users who need efficient clarification of liquids with minimal solid content. It is particularly useful where precision and clarity are important, such as in the biotechnology, chemical, and food sectors. While manual cleaning is required after each use, the centrifuge compensates with its consistent performance and simple operation.

For those seeking a separation solution for fine particles and clear liquids, GN Separation welcomes the opportunity to support your processing needs.
