The main purpose of milk clarification is to remove impurities. Many clarifiers can only be used for either hot or cold milk, but with Tetra Pak® Clarifiers, you can process both. The efficiency of the removal of smaller particles increases with the temperature, and the most efficient reduction of leucocytes and bacteria is achieved at 50–60 °C.
To maintain optimum fat separation and long run times, it is necessary to remove cheese fines from the whey before it reaches the whey separator. Installing a centrifugal clarifier upstream of the whey separator is the most efficient way to remove cheese fines. Clarification normally takes place at the same temperature as whey separation, i.e. at vat temperature.

Hermetic inlet seals
Outside the clarifier, the piping is connected to a rotating spindle by hermetic seals. This prevents any air from entering the clarifier and any product from leaking out. The absence of air minimizes the risk of reducing particle and aggregate size. It enables better clarification efficiency at a lower rotation speed and hence lowers energy consumption.
By contrast to competing models, in Tetra Pak® Clarifiers 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. This ensures that the size of particles and aggregates is always maintained.
Corrosion resistant bowl
Thanks to the AirTight technology upon which they are based, Tetra Pak® Clarifiers offer a superior clarification 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
The product exits the clarifier via hermetic outlet seals. This prevents overflow. It also prevents unwanted air entering the machine, which could split the fat globules and cause product foaming downstream.
Product discharge pump
The product leaves the clarifier through a rotating pump. The use of a pump - as opposed to the paring disc - makes it possible to run a wide range of capacities in the same machine without any mechanical alterations. It also increases energy efficiency.
