Typically COP systems are open tanks where a given cleaning solution can be heated and re-circulated.
When using a COP system, workers must take equipment apart or move it from the production area to a cleaning area. The parts are rinsed, sanitized and reassembled.
In the past, regulatory agencies have used fluid flow force to judge whether a cleaning system is adequate.
COP units have a pump that recirculates the cleaning solution and rinse water, and distribution headers that agitate the cleaning solution. A COP unit can also serve as the recirculating unit for CIP operation.
The normal wash cycle takes about 30 to 40 minutes and the cold acid or sanitizing rinse talks about 5 to 10 minutes more.
