The 3-Phase Separating Decanter is a centrifuge in which two liquids of different densities are separated from each other. At the same time solids are separated and discharged.
The feedstock enters the decanter through feed tube and flows into the centrifugation space through the distributor. The conveyor screw transports the solids to the solids discharge. The level of the liquid can be adjusted by fitting regulating rings or disks of the required inner diameter. Separation of the two liquid phases takes place in the separation zone, whereby the light phase flows towards the bowl axis, and the heavy phase towards the bowl wall.
Regarding the discharge of the liquid phases 3-Phase Separating Decanters are available in numerous designs. Liquid phases can be discharged by gravity or under pressure by centripetal pump.
In the case of a 3-Phase Separating Decanter with centripetal pump for the light phase and gravity discharge of the heavy phase, the light liquid phase leaves the centrifugation space over an exchangeable regulating ring and is discharged under pressure by the centripetal pump. At the same time, the heavy liquid phase is discharged under gravity through exchangeable regulating tubes.
Another technical variant is the case of a 3-Phase Separating Decanter with centripetal pump for the heavy phase and gravity discharge of the light phase. The choice of the appropriate design depends on the product to be separated and the lay-out of the customer installation.

Thermoforming has long played a central role in food packaging. Now it is facing a major shift. As regulations tighten, materials evolve and costs rise, form fill seal lines must do more than run reliably – they now shape how food stays fresh, affordable and recyclable. Take a look at the key thermoforming trends informing the food packaging and delivery landscape.

From the orchards of the Cape to store shelves across 40 countries, the South African packhouse Betko has built a business on freshness, timing and reliability. With GEA’s controlled atmosphere refrigeration technology, the company can now store apples and pears for up to 14 months and cut energy consumption by 20%, with a partnership of more than 30 years at the heart of it all.
