What Is a Disc Centrifuge?

The disc centrifuge, also known as a disc stack separator or disc bowl centrifuge, is a high-speed separation machine designed for continuous liquid–solid or liquid–liquid separation. It utilizes a stack of conical discs inside a rotating bowl to generate powerful centrifugal force, efficiently separating fine particles or immiscible liquids.

Our centrifuge is widely used in food processing, biotechnology, pharmaceuticals, marine oil purification, and wastewater treatment industries due to its high separation efficiency and compact footprint.

How Does a Disc Stack Centrifuge Work?

Inside the centrifuge bowl, a vertical stack of conical discs creates multiple separation zones. When the mixture enters through the feed inlet:

Centrifugal force (up to 10,000 g) pushes heavier solids toward the bowl wall.

Lighter liquid phase moves toward the center and is discharged through a separate outlet.

Some models feature a self-cleaning mechanism, automatically discharging collected solids.

This continuous operation makes disc stack centrifuges ideal for high-volume industrial processes requiring consistent separation performance.

Main Features of Industrial Disc Centrifuges

High rotational speed: Ensures fast and efficient clarification.

Self-cleaning design: Reduces downtime and manual maintenance.

Compact and enclosed construction: Minimizes contamination risk in food and biotech applications.

Energy-efficient drive system: Lower operational costs.

Optional PLC control system: Enables automation and process monitoring.

Applications of Disc Bowl Centrifuges

1. Food & Beverage Industry

Used for clarifying milk, juice, wine, and beer, removing impurities and improving product clarity.

2. Biopharmaceutical & Biotechnology

Critical for cell harvesting, protein recovery, and vaccine production, ensuring high purity and yield.

3. Edible Oil and Marine Oil Purification

Separates water and fine solids from oils, increasing oil quality and shelf life.

4. Chemical and Wastewater Treatment

Used for liquid–solid separation in chemical manufacturing and oil–water clarification in environmental plants.
