PROBLEM TO BE SOLVED: To minimize unevenness of heating amount in a thermal sterilization device for thermally sterilizing a number of sterilization objects 2 housed in a sterilization tank 1 by spraying hot water within the sterilization tank 1.SOLUTION: In the thermal sterilization device for thermally sterilizing the sterilization objects 2 by housing a number of trays with the sterilization objects 2 being placed thereon in the sterilization tank 1 in a multilayer manner and spraying hot water toward the sterilization objects 2 through an injection nozzle 9 provided within the sterilization tank, the hot water is stored at the bottom of the sterilization tank 1, and circulated and sprayed by blowing steam into the bottom of the sterilization tank. A baffle plate 12 for preventing the steam for hot water heating from directly heating the sterilization objects 2 is provided between a steam blowing portion 13 at the bottom in the sterilization tank and the sterilization objects 2. The baffle plate 12 includes holes for dispersively passing the steam.COPYRIGHT: (C)2013,JPO&INPIT【課題】殺菌槽1内で熱水を噴射して殺菌槽内に収容した多数の被殺菌物2を加熱殺菌する加熱殺菌装置において、加熱量のばらつきを小さくする。【解決手段】殺菌槽1内に被殺菌物2を乗せ置いたトレイを多数段積み重ねた状態で収容し、殺菌槽内に設けた噴射ノズル9から被殺菌物2に向けて熱水を噴射して被殺菌物2を加熱殺菌する加熱殺菌装置であって、熱水は殺菌槽1の底部にためておき、殺菌槽底部に蒸気を吹き込むことで加熱した熱水を循環させて噴射するようにしている加熱殺菌装置において、殺菌槽内底部の蒸気吹き込み部13と被殺菌物2の間に、熱水加熱用の蒸気が被殺菌物2を直接加熱することを防止するためのじゃま板12を設ける。また、じゃま板12には蒸気を分散して流すための穴を開けている。【選択図】図1
