Tetra Pak has launched the Tetra Centri Airtight Eco hermetically sealed direct-driven dairy separator.

Suitable for all dairy customers with high-capacity production, the Tetra Centri Airtight Eco separator reduces the energy consumption of an overall separation system by up to 35 per cent compared to conventional paring disc separators and doubles production time between major services compared to belt-driven separators, according to the company.

The Tetra Centri Airtight Eco separator features the Edrive system, the Emotion system and the Econ control system.

The gearless Edrive is a patented direct-drive system in which the motor is directly connected to the separator spindle and incorporated into the separator bowl without a gear.

This increases uptime and reduces costs compared to belt-driven separators.

With fewer moving parts and less wear and tear, the simple mechanics of the Edrive extends production time between major services from 8,000 hours to up to 16,000 hours.

It also uses 90 per cent less lubrication oil than previous systems.

The patented Emotion system reduces friction inside the separator, reducing energy loss and the energy consumption of the separator itself by more than 50 per cent.

This translates to a possible 35 per cent reduction in the energy consumption of an overall separation system compared to conventional paring disc separators.

Added benefits are the reduction of noise levels by 3dB(A) and the reduction of machine surface temperature.

Econ is a fully embedded control system, which handles all of the separator’s support functions, such as cooling, lubrication and discharge.

This enables dairies to simplify and improve the monitoring, status reporting and reliability of the systems and decreases the number of unplanned stops.

The Tetra Centri Airtight range of separators includes the hermetic seals at the inlet and outlet, preventing the intake and exposure of the product to destructive air.

In the Tetra Centri Airtight Eco separator, the product is fed smoothly into the separator bowl from the bottom through the new Edrive, which ensures that the size of fat globules and particles is maintained.

This ensures that the separability of fat and impurities and the concentration of cream are efficient.
