Krones UniPure S decanter technology

With the UniPure S, Krones is expanding its UniPure product family to include 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 220–800 mm.

The unit 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 also be used for plastics recycling. It provides gentle handling of sensitive products like yoghurt, cream or fruit chunks, without impairing its 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 0–120 m³/h and make it possible to process loads of up to 25 tons per hour. They have speeds as high as 5100 revolutions per minute, reaching a centrifugal acceleration of up to 3200 G. Thanks to a maximum capacity of three tons per hour and a hydraulic throughput of seven cubic metres an hour, the decanter can provide a level of performance that is also suited for handling large material volumes.

The design prevents product residues, which makes cleaning easier and also meets stringent hygiene standards. 

It is available with ATEX certification for flammable products like spirits.
