HIGH PRESSURE STEAM STERILIZATION DEVICE

To shorten a drying period by improving drying performance.SOLUTION: A high pressure steam sterilization device A comprises: a sterilization tank 1 storing therein an object to be sterilized; drive gas supply means 2 generating a drive gas and supplying the drive gas to the sterilization tank 1; an ejector 3 sucking the gas in the sterilization tank 1 and discharging the sucked gas to outside, thereby reducing pressure in the sterilization tank 1; steam generation means 4 generating steam in the sterilization tank 1; and control means 6 sequentially performing at least, a sterilization step of steam sterilizing the object to be sterilized in the sterilization tank 1, and a discharge step of discharging steam and residual water in the sterilization tank 1. The control means 6 executes a drying step which repeats pressure reduction in the sterilization tank 1 by the ejector 3, and supply of the drive gas to the sterilization tank 1 by the drive gas supply means 2, to thereby dry the object to be sterilized.SELECTED DRAWING: Figure 1 【課題】乾燥性能を向上させて、乾燥時間を短縮させること。【解決手段】高圧蒸気滅菌装置Ａは、被滅菌物が収容される滅菌槽１と、駆動気体を生成して滅菌槽１に駆動気体を供給する駆動気体供給手段２と、滅菌槽１内の気体を外部へ吸引排出して滅菌槽１内を減圧するエジェクタ３と、滅菌槽１内に蒸気を発生させる蒸気発生手段４と、少なくとも、滅菌槽１内の被滅菌物を蒸気滅菌する滅菌工程と、滅菌槽１内の蒸気及び残留水を排出する排出工程と、を順次に実行する制御手段６と、を備えている。制御手段６は、エジェクタ３による滅菌槽１内の減圧、及び、駆動気体供給手段２による滅菌槽１内への駆動気体の供給を繰り返し、被滅菌物を乾燥させる乾燥工程を実行する。【選択図】図１
