UniPure S: Krones is adding decanter technology to its portfolio

With the new UniPure S, Krones 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 reliably separate solids from liquids. It serves the entire centrifuge size range with bowl diameters from 220 to 800 millimetres.

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. 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.

Technical data that speak for themselves

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 wide variety of process requirements.

The UniPure S presented at this year’s drinktec boasts a persuasive technical performance, with speeds as high as 5,100 revolutions per minute, reaching a centrifugal acceleration of up to 3,200 G. Thanks to a maximum capacity of three tons per hour and a hydraulic throughput of seven cubic metres an hour, the decanter boasts a level of performance that is also suited for handling huge material volumes.

With all dead spaces eliminated, the design prevents product residues, makes cleaning a whole lot easier and also meets ultra-stringent hygiene standards. At the same time, its sturdy construction ensures a high level of reliability as well as minimised downtimes and low operating costs.

What’s more, the UniPure S is available with ATEX certification for flammable products like spirits. (The EU’s ATEX Directive 2014/34/EU covers equipment and protective systems intended for use in potentially explosive atmospheres.) 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.
