Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus and method for inert gas-substituted packaging, capable of a large amount of inert gas substitution at a high substitution ratio; while conventionally encapsulation of bread or sponge cakes in an inert gas such as nitrogen has a low substitution ratio of inert gas due to air bubbles contained in porous bread and sponge cakes, with inadequacy for mass production.SOLUTION: An apparatus 1 for inert gas-substituted packaging includes an inert gas substitution device 1 for gas substitution in a bread 4 to be packaged by repeating decompression in a vacuum chamber 7 and subsequent compression in the vacuum chamber 7 with injection of inert gas at ambient pressure or higher, and a pillow packaging machine 3 for pillow-packaging the gas-substituted article to be packaged. A method for inert gas-substituted packaging includes repeating a plurality of times of the step of decompression and compression of the bread 4 at ambient pressure or higher with decompression in a vacuum chamber 7 and subsequent compression in the vacuum chamber 7 with injection of inert gas. 【課題】パン類やカステラ等を窒素ガス等の不活性で封入する場合、パン類やカステラ等は多孔質で気泡があるため、不活性ガスの置換率が悪く、しかも、従来の技術では大量生産に不向きだったので、不活性ガスの置換率が高く、大量にガス置換が可能な不活性ガス置換包装装置及び不活性ガス置換包装方法を提供する。【解決手段】不活性ガス置換包装装置１は、真空チャンバー７内を減圧した後に、不活性ガスを導入して真空チャンバー７内を大気圧以上に加圧と、減圧と加圧を繰り返して被包装物であるパン４のガス置換をする不活性ガス置換装置１と、ガス置換した被包装物をピロー包装するピロー包装機３とを備えた不活性ガス置換包装装置。また、不活性ガス置換包装方法は、真空チャンバー７内を減圧した後、不活性ガスを導入して真空チャンバー７内を加圧して、パン４を減圧と大気圧以上で加圧することを複数回繰り返す方法である。【選択図】図１
