PROBLEM TO BE SOLVED: To increase a volume of steam per a unit time for supplying into a sterilizing tank and to shorten an operating time of a sterilizing device by a steam providing a plurality of sterilizing devices having a steam producing means and by connecting each sterilizing tank of these sterilizing devices and each steam producing means to each other with steam pipes. SOLUTION: In three sterilizing devices 1, for example, when a central sterilizing device 1 is in operation and right and left sterilizing devices 1 are on standby, all three devices are made to operate in such a way that a steam producing means 2 of the central sterilizing device 1 is also in operation, and each steam producing means 2 provided on the standing-by sterilizing devices 1 is further in operation. Each openable valve 12 is in an open state, right and left steam supplying valves 9 are in a closed state, and only central steam supplying valve 9 is in an open state. A volume of supplying steam for sterilizing per a unit time which is supplied from the three steam producing means 2 to the central sterilizing tank 3 is increased three times thereby, and a time necessary for a steam pressure in the sterilizing tank 3 to reach a fixed pressure corresponding to a sterilizing temperature can be greatly shortened and operation time can be further shortened. |
