ABSTRACT:
The present invention is directed to automatic, self-contained cleaning and sanitizing equipment. It includes a first liquid holding tank for a cleaning solution and a second liquid holding tank for a sanitizing solution. A cleaning line runs from the first tank and has an outlet adapted for connection to an item to be cleaned, and a cleaning return line runs back to the first tank and has an inlet adapted for connection to the item to be cleaned. A sanitizing line runs from the second tank and has an outlet connected directly to the item to be cleaned, or to the cleaning line so as to create a common connection to the item to be cleaned, and a sanitizing return line runs back to the second tank directly from the item to be cleaned, or from the cleaning return line so as to create a common connection running from the item to be cleaned. There is a first pump connected to the equipment for circulating liquid from the first tank to the item to be cleaned and back to the first tank through the cleaning return line and a second pump connected to the system for circulating liquid from the second tank to the item to be cleaned and back to the second tank through the sanitizing return line. An ozone generator is included on the second tank or the sanitizing line for inclusion of ozone therein and for creation of an ozone-based sanitization liquid therein.
