D Series | Alfa Laval

D Series

Alfa Laval’s high-performing D Series of separators has been specifically developed for the demands of milk and whey clarification in the dairy industry. The series features a range of models to meet different capacity needs, as well as unique innovations that ensure efficient, reliable, and cost-saving separation.

Dairy PX 18 D and BB Series

Discover your ideal clarifier for milk or whey

  • 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

Superior clarification performance for milk and whey

The objective of milk clarification is to remove somatic cells and impurities. While many clarifiers can only be used for either hot or cold milk, the Alfa Laval D Series can process both. In whey clarification, removing cheese fines from whey before it reaches the separator is necessary for maintaining optimum fat separation and long run times. Alfa Laval D Series separators take care of clarification upstream of the whey separator, which is the most efficient way to remove cheese fines.
