PROBLEM TO BE SOLVED: To save space and allow effective heating of a sterilization tank by heat radiation from a steam generating means by providing a sterilization tank heating means and providing the steam generating means using this heating means as a heat source integrally with the sterilization tank. SOLUTION: The left wall of a sterilization tank 1 is vertically provided with a plurality of heating tubes 3 for heat source as a heating means 2 for heating the sterilization tank 1. A water tube 4 is coaxially penetrated in this heating tube 3 for heat source to form a double-tube structure and to constitute a steam generating means 5. The upper tips of the heating tubes 3 for heat source are connected with a heating fluid supply line 8 via a first upper header 6. The bottom is connected with a first discharge line 10 provided with a first steam trap 9 via a first lower header 7. Thus, general purpose steam is commonly used as heating fluid for heating and sterilization, and discharged as drain. Therefore, space can be saved, and sterilization can be performed by heat radiation from the steam generating means 5. |
