WITH the new UniPure S, Krones revealed it is expanding its ‘field-proven’ UniPure product family to include high-performance decanters.
While the classical UniPure F model works with filter candles, the UniPure S decanter uses centrifugal force to separate solids from liquids. It serves the entire centrifuge size range with bowl diameters from 220 to 800mm.
The UniPure S has been specifically designed for use in the food and recycling industries. It removes particles, suspended matter and microorganisms from juices, oils, dairy products and plant-based raw materials, and can even be used for plastics recycling.
Krones added that it provides gentle handling of sensitive products like yoghurt, cream or fruit chunks, without impairing their texture. The technical heart of the process is a screw conveyor located inside the bowl that continuously moves the separated solids to the discharge area.
The decanters cover a hydraulic throughput range of 0 to 120 m³/h and make it possible to process loads of up to 25 tons per hour – ideal preconditions for a variety of process requirements.
The UniPure S, presented at Drinktec 2025, boasts speeds as high as 5,100 revolutions per minute, reaching a centrifugal acceleration of up to 3,200 G. Due to a maximum capacity of three tons per hour and a hydraulic throughput of seven cubic metres an hour, the decanter features a level of performance that is also suited for handling huge material volumes.
With all dead spaces eliminated, Krones explained that the design prevents product residues, makes cleaning easier and meets ultra-stringent hygiene standards. At the same time, its ‘sturdy’ construction is designed to ensure a high level of reliability as well as minimised downtimes and low operating costs.
The UniPure S is available with ATEX certification for flammable products like spirits. The heat-resistant procedure is also suitable for hot filling and processes requiring an exacting thermal profile.
“With the decanter, Krones is adding a new technology to its product family that meets the rising requirements posed by the food and recycling industries and expanding its existing portfolio to include a powerful solution for challenging separation processes,” the firm stated.
