BB and BM series

The Alfa Laval BB and BM Series is the market’s most advanced series for bacteria and spore removal in the dairy industry. They feature patented Alfa Laval technologies that ensure efficient, reliable, and cost-saving separation.


Advanced technology for milk bactofugation

  • Alfa Laval’s unique bottom-fed Hermetic Design provides superior skimming efficiency and maintains premium product quality
  • The bottom-fed design reduces shear forces for gentle product treatment that preserves the size of the fat globules
  • Hermetic seals on inlet and outlet prevent oxidation and reduce the foaming of the milk
  • Easy adaptation to process conditions provides increased production flexibility and efficient CIP
  • Energy savings of up to 60% thanks to the Hermetic Design

Alfa Laval sets the market standard with the Bactofuge® design

The BB and BM Series feature our patented Bactofuge® technology. These separators can be used for pre-treating cheese milk, where butter acid spores (anaerobic spores) are removed. They are also used to enhance the quality of milk powders, consumption milk and cream, thanks to the efficient removal of aerobic spores such as Bacillus cereus. Separation efficiency (defined as the percentage of the reduction of incoming level of bacteria and spores) can often reach up to 99%. For installations with particularly high demands, two or more units can be installed in series. The addition of unique features such as Alfa Laval eMotion™ and our bottom-fed, Hermetic Design also ensure high energy efficiency, compliance with the strictest hygienic standards and very low total cost of ownership.


Saving energy, cutting costs

Alfa Laval separators with Hermetic Design are the most energy-efficient on the market. When our unique eMotion technology is added, minimized air friction brings additional power reduction. Combined, our unique design and technologies can deliver up to 70% energy reduction compared to non-hermetic alternatives on the market.
