PROBLEM TO BE SOLVED: To achieve intended sterilization by surely immersing a material to be treated present in a treatment tank into hot water, in a sterilizer of a hot-water storage type.SOLUTION: A sterilizer includes a treatment tank 2 in which a material 4 to be treated is stored, a hot-water storage tank 3 for storing water to be fed into the treatment tank 2, a means 14 of heating the treatment tank for heating water stored in the treatment tank 2, and a means 18 of heating the hot-water storage tank for heating water stored in the hot-water storage tank 3. A material 4 to be treated is received in the treatment tank 2 and hot water from the hot-water storage tank 3 is stored therein, and water stored in the treatment tank 2 is kept at a prescribed temperature by the means 14 of heating the treatment tank to heat and sterilize the material 4 to be treated. In the sterilizing process, water is stored in the hot-water storage tank 3 and the water stored therein is kept at the prescribed temperature by the means 18 of heating the hot-water storage tank. If the water level in the treatment tank 2 falls below the minimum water level, hot water is supplied from the hot-water storage tank 3 to the treatment tank 2 until it reaches a prescribed water level. |
