Tubular Centrifuge for Brewer's Yeast Separation
The tubular centrifuge (also called a supercentrifuge) is a high-speed centrifugation device widely used for separating fine particles or biological materials like brewer's yeast (Saccharomyces cerevisiae) from liquid suspensions in industries such as brewing, biotechnology, and pharmaceuticals. Below is a brief overview of its application in brewer's yeast separation:
High-Speed Rotation: Operates at extremely high speeds (typically 15,000-50,000 rpm), generating centrifugal forces up to 50,000-100,000×g, which rapidly separates yeast cells from the liquid phase (beer or fermentation broth).
Continuous Separation: The tubular design (long, narrow rotating cylinder) allows for continuous feed and discharge, making it efficient for large-scale processing.
Density Difference: Yeast cells (denser) are forced toward the centrifuge wall, while clarified liquid (less dense) flows toward the center and exits through an outlet.
Feed Introduction: Yeast-containing liquid is pumped into the rotating tubular bowl.
Centrifugal Sedimentation: Yeast cells settle against the bowl wall due to high G-force.
Liquid Discharge: Clarified beer or supernatant exits through a central outlet.
Yeast Recovery: Accumulated yeast is manually or automatically discharged periodically.
High Efficiency: Rapid separation of micron-sized yeast cells (1-10 μm).
Gentle Handling: Minimal shear stress preserves yeast viability for reuse in fermentation.
Compact Design: Suitable for sterile processes in brewing and bioprocessing.
