Tetra Pak® Bactofuge unit

Units for removal of spores and bacteria, or concentration of protein

  • Excellent product quality since hermetic seals prevent intake of destructive air
  • AirTight technology enables superior spore and bacteria removal efficiency
  • Bactofuge units designed for unmatched flexibility in both capacity and recipe range

​​​​​​​​​​​​Tetra Pak® Bactofuge​ unit​​

Tetra Pak® Bactofuge units are traditionally incorporated in the pre-treatment of cheese milk, where typically butter acid spores (Anaerobic spores) are removed. Bactofuge units are also used to enhance the quality of powders, consumption milk and cream where typically aerobic spores (e.g. Bacillus Cerus) are removed.

The efficiency of the unit is stated as a percentage reduction of the incoming level of bacteria and spores. Generally, the efficiency can go up to 99 %. For installations with high demand on efficiency, two or more units can be installed in series.

Features

Hermetic inlet seals

Superior spore and bacteria removal and energy efficiency

Outside the unit, the piping is connected to a rotating spindle by hermetic seals. This prevents any air from entering the Bactofuge unit and any product from leaking out. The absence of air minimizes the risk of particle and aggregate size being reduced. It enables better spore and bacteria removal efficiency at a lower rotation speed and hence lowers energy consumption.

Hollow spindle

Gentle treatment safeguards product quality

By contrast to competing models, in Tetra Pak Bactofuge units 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

Increases bowl lifetime, saves money

Thanks to the AirTight technology upon which our Bactofuge units are based, they offer a superior spore and bacteria removal 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 Bactofuge unit via hermetic outlet seals. This prevents overflow and, depending on the model, the unwanted mixing of the clean milk with the spore and bacteria enriched milk. It also prevents unwanted air entering the machine, which could split the fat globules and cause product foaming downstream.

Product discharge pumps

Enables flexibility and low energy consumption

The product leaves the Bactofuge unit through one or two rotating pumps, depending on model. The use of pumps - as opposed to the 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.
