Automatic WIP-Systems (photo) provide a reliable and repeatable process for cleaning mixing systems — such as the Ploughshare Mixers — an important task especially in life-science applications. A smart arrangement of rotating cleaning nozzles inside the mixing drum ensures a thorough rinsing of all product contact surfaces without any need for filling the machine with cleaning media. By simultaneous rotation of mixing elements and cleaning nozzles, any spray shadows are avoided. The gear-driven rotating flat fan nozzles guarantee an intensive and uniform cleaning of all surfaces. Besides the rotating cleaning nozzles inside the mixing drum, the seals for the mixing elements and choppers are purged with water and all ports on the machine are cleaned effectively by static, locally installed cleaning nozzles. — Lödige Process Technology, Paderborn, Germany
