As brewery processes and operations grow more complex, sanitation problems often arise. Many of these sanitation issues can be traced back to fluid mechanical issues. This paper will look at some commonly found problems in the field and discuss both solutions and approaches for the brewery to stay ahead of these problems. CIP system design will be discussed and design considerations given. From CIP spray ball pressures and designs to balancing flow in closed systems, many common fluid mechanical issues can be avoided if just a few simple rules are being followed. Specific examples will be given from the field and step-by-step troubleshooting guides.
