Abstract
A single motive pump, clean-in-place system is disclosed for use with an associated piping system and with a vessel to be cleaned of contaminating material. The system comprises a recirculation loop, a return line from the vessel to the recirculation loop, and a feed line from the recirculation loop to the vessel. During a wash recirculation cycle, the system uses a single motive pump to provide recirculation flow, feed flow, and, via an eductor pump, return suction from the vessel. An alternate embodiment of the clean-in-place system uses a water storage tank when adequate water flow rate or supply pressure are unavailable.
