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.
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.
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.
Sustainable is our standard
Alfa Laval wants to help dairy producers make optimal use of every resource in their process. That’s why we build high-efficiency dairy separators that prevent product waste while consuming less energy and water, thanks to unique innovations. Letting you deliver top-quality products that leave a smaller environmental footprint.
Features that make the difference
What sets Alfa Laval separators apart is what’s on the inside: a broad scope of unique and patented technologies that, taken together, help dairy customers achieve improved product quality along with superior hygienic confidence. They also make it possible to drastically decrease both water and energy consumption, reducing both operational costs and environmental footprint.
Hermetic Design™
Gentle acceleration, powerful efficiency
A unique air-tight bowl that enables improved product quality and drastically reduces power consumption.
eDrive™
Mechanical simplicity for higher efficiency and lower costs
A direct-drive system with fewer rotating parts that minimizes both maintenance and energy costs.
UniDisc™
New levels of capacity and hygiene
A radical new disc design that decreases cleaning needs while increasing flow rate by up to 20%.
eMotion™
Double the output per kWh
An innovation to minimize friction, which cuts the separator´s energy consumption and CO2 footprint by up to 70%.
Bactofuge®
Outstanding solids capacity
Continuous solid discharge ensures an intact and highly concentrated stream for onward processing or as a valuable by-product. This makes it possible to increase separation capacity.
