PROBLEM TO BE SOLVED: To provide a vegetable sterilizer reliably preventing leakage of ozone gas to the outside while inhibiting elimination of ozone gas, and a method for producing sterilized vegetables.SOLUTION: A vegetable sterilizer 100 includes a sterilization tank 3 for sterilizing vegetables V by soaking in ozone water, and has an airtight block 30 above the ozone water accumulated in the sterilization tank 3. A method for producing sterilized vegetables includes: a sterilization step of sterilizing by soaking vegetables in ozone water in an ozone water sterilization tank 30 in which ozone water is accumulated and a space above the accumulated ozone water is made airtight an air supply step of making an air pressure in a preliminary washing tank 20 included in the front stage and the back stage of the ozone water sterilization tank 30, and in a post-washing tank 40 higher than an air pressure in the ozone water sterilization tank 30 and a transfer step of transferring the vegetables between the preliminary washing tank 20 and the post-washing tank 40 whose air pressures are increased in the air supply step, and the ozone water sterilization tank 30.COPYRIGHT: (C)2016,JPO&INPIT【課題】オゾンガスの脱離を抑制しつつオゾンガスの外部への漏出をより確実に防止可能な野菜殺菌装置及び殺菌野菜の生産方法を提供する。【解決手段】オゾン水に浸漬させて野菜Vを殺菌する殺菌槽3を備え、殺菌槽3に貯留された前記オゾン水の上方の区画30が気密化されている野菜殺菌装置100とする。また、オゾン水が貯留されており、貯留されたオゾン水の上方の空間が気密化されたオゾン水殺菌槽30において、野菜をオゾン水に浸漬させて殺菌を行う殺菌ステップと、オゾン水殺菌槽30の前段及び後段に備えられた予備洗浄槽20、後洗浄槽40内の気圧を、オゾン水殺菌槽30内の気圧よりも高くする給気ステップと、前記給気ステップにおいて気圧が高められた予備洗浄槽20、後洗浄槽40と、オゾン水殺菌槽30との間で野菜を移送する移送ステップと、を含む殺菌野菜の生産方法とする。【選択図】図1
