PROBLEM TO BE SOLVED: To provide a steam sterilizing device using a clean steam generator, which can improve the heating efficiency of a heater and can be miniaturized. SOLUTION: In a steam generator 10 provided with a longitudinal heat exchanger 12 to which heated steam is supplied on the outer surface side of heat conduction pipes 18 and which is arranged with vertical plural heat conduction pipes 18 and a longitudinally long storage tank 14 for storing clean water 28 for circulating/heating the clean water 28 in the storage tank 14 by thermo- siphon operation while mutually communicating the lower sides and upper sides of the heat exchanger 12 and the storage tank 14, the steam sterilizing device is provided with a clean steam generator 10 provided with a removing means 30 and a take-out port 40 for drops of water, or the like, generated inside the heat conduction pipe 18 on the upper side in the storage tank 14 and provided with a water level control means for making the surface of the clean water 28 in the storage tank 14 half or lower of the pipe length of the heat conduction pipe 18, and a control means for controlling the flow rate of clean steam to be supplied. |
