Tetra Pak® Separators

AirTight design for high profitability

  • Excellent product quality since hermetic seals prevent intake of destructive air
  • AirTight technology enables superior separation efficiency
  • Separator designed for unmatched flexibility in both capacity and recipe range

​Tetra Pak® Separator​s

Tetra Pak® Separators ensure high capacity and efficient performance in milk skimming. Smooth product treatment results in greater skimming efficiency and reduced energy consumption. The separators maintain the quality of your products by preventing air from entering the process.

The AirTight technology features a completely filled separator bowl. An advanced inlet and outlet design ensures gentle treatment during the entire separation process.


Units for hot or cold separation of cream from milk

Capacity: Hot milk separation is between 7 000-75 000 l/h and for cold milk separation is between 10 000 to 50 000 l/h.

Hermetic inlet seals

Superior separation and energy efficiency

Outside the unit, the piping is connected to a rotating spindle by hermetic seals. This prevents any air from entering the separator and any product from leaking out. The absence of air in the separation process minimizes the reduction in fat globule size. It enables better separation efficiency at a lower rotation speed and hence lowers energy consumption.

Hollow spindle

Gentle treatment safeguards product quality

By contrast to competing separators, in Tetra Pak® Separators the product enters the bowl smoothly and accelerates gradually as it passes through the rotating spindle. This, combined with the absence of air in the system, means the product is handled gently. It also ensures that the size of fat globules and particles is maintained.

Corrosion resistant bowl

Increases bowl lifetime, saves money

Thanks to the AirTight technology upon which our Tetra Pak® Separators are based, they offer superior separation efficiency at a lower speed. This enables the use of a steel quality with higher corrosion resistance, which, in turn lengthens the lifetime of the bowl.

Hermetic outlet seals

Maintains product quality

The product exits the separator via hermetic outlet seals. This prevents overflow and the unwanted mixing of skimmed milk and cream. It also prevents unwanted air entering the machine, which could split the fat globules, leading to free fat and possibly also free fatty acids (FFA) as well as product foaming downstream.

Product discharge pumps

Enables flexibility and low energy consumption

The product leaves the separator through two rotating pumps: one for skimmed milk and one for cream. The use of pumps - as opposed to paring discs - makes it possible to run a wide range of capacities in the same machine without any mechanical alterations. It also increases energy efficiency.


Encapt (TM) technology

Revolutionary energy-saving technology for high-capacity separators

By lowering pressure and reducing air friction around the separator bowl, EncaptTM cuts the energy consumption of a Tetra Pak® Separator with AirTight technology by up to 40% compared to other separators.* This improves both operational cost and environmental impact. It is achieved through a combination of a low-pressure pump, discharge pump, water lock and hermetically sealed outlet

*Numbers refer to a production scenario of hot milk skimming at 55 000 l/h including feed and booster pumps.

INSTAL module

Decreases installation time

The INSTAL module is delivered as an assembled and pre-tested unit ready for production.

Consists of:

  • Stainless-steel frame
  • All peripherals necessary for operations
  • Assembly and pre-testing

Polynode Disc

Major breakthrough in separator disc technology enables higher capacity and higher performance.

Innovative, one-piece disc construction means the separator can accommodate more discs, increasing separation surface and improving skimming performance. Eliminating traditional welded spacers and replacing them with streamlined, machine-embossed polynodes enables increased stability, higher flow rate and improved performance.

Today, available for hot milk skimming at high capacity – Tetra Pak® Separator H80.
