Spray nozzles clean the decanter bowl not only from the outside but also from the inside. With our unique double-walled feed pipe and an array of additional nozzles you can even clean the inside of the scroll body and the gaps of the centripetal pump
The specifically designed box distributor allows for superb cleanability due to its straight and simple design.
During CIP, we first speed up the bowl to maximum speed to use as much centrifugal force as possible to get the surfaces clean. In the second phase of our CIP cleaning cycle the speed is reduced and the liquid ring collapses. This leads to high splashing and turbulence inside the bowl with the result that the CIP liquid hits every corner and every spot.
We use only high-quality stainless steel for all product-contacting parts. But it’s not the quality of the material alone that makes for good cleaning, you also need the expertise to make gaps and seals cleanable and surfaces smooth. The smoother the surface, the better the cleanability. Our decanter parts can be supplied with a surface roughness of Ra = 0.8 µm
Last but not least, our Varipond P feature gives you more than just high yields. It has proven to be extremely useful for cleaning, especially when you look at the decanter’s solids side with the solid outlet and the catcher. If you apply pressurized air during CIP, you can operate the decanter to flood the solids side. Flooded decanter operation means you discharge liquid through the solid outlet – something you cannot do with a standard decanter. The additional pressure pushes the CIP liquid up the cone, through the solids discharge and the catcher cleaning everything on its way out.
Varipond P Automatic operation
And when your cleaning cycle is done, and you are ready to process product once again, we have automated the Varipond P. This automation feature connects the automatic start and stop of the Varipond P to an operator adjustable torque value. As long as torque is below the set torque value, Varipond P is automatically shut off. Torque comes with solids. No solids in the bowl, no torque. The more solids in the bowl, the higher the torque. Once your decanter’s solids side is properly filled with solids, Varipond pressure is applied. Otherwise liquid might flood out the solids discharge. If torque drops, the Varipond turns off the pressure to reduce the pond, avoiding the flood.
