What are the differences between Static and Dynamic spray balls in CIP machines?
The typical considerations in using either static or dynamic spray balls are that static spray balls can be placed strategically within a mixer to try to assure spray contact with all sides of various mixing apparatus inside the tank. Static spray balls typically rely on a high-volume, low-flow cascading cleaning action wherein much of the mechanical energy comes from the sprayed on solution running down the sides and surfaces of the tank being cleaned. Dynamic spray balls have low-volume, high-pressure spray with the spray nozzle spinning around while simultaneously rotating to direct a jet of spray to all interior surfaces of the tank. Dynamic spray balls have more mechanical energy applied during cleaning. There are concerns with the possibility that dynamic spray balls can jam up and stop rotating or stop spinning during a cleaning cycle. Dynamic spray ball manufacturers are developing sensors that monitor the performance of the spinning and rotating to be able to document and verify correct performance. When designed and installed properly, both kinds of spray balls can provide reliable cleaning. When using CIP systems with either static or dynamic spray balls in large tanks and mixers, Alconox, Inc recommends using low foaming detergents such as alkaline Solujet or acidic Citrajet.
