ABSTRACT:
A method and apparatus using steam to sterilize liquid dispensers. This is achieved by injecting steam into a drained dispenser machine equipped with a cover having a safety valve that matches the top of the dispenser to provide sealing. The steam is generated by a steam generator physically integrated with the new liquid dispenser machine. The steam circulates through the fluid compartment of the liquid dispenser and continues through its conduits and exits at the taps which are held open by a stepped boss. The sanitizing period can be adjusted and controlled. After sterilizing the machine, the cap of the dispenser is removed and its taps are released in order to return the machine back to its normal operation.
