Description
図1は、第1実施形態に係る滅菌装置100の構成を示す概略図である。滅菌装置100は、滅菌ガスで滅菌対象物を滅菌する。本実施形態で用いられる滅菌ガスを構成する物質は、主として過酸化水素(H2O2)及びオゾン(O3)である。
図6は、第2実施形態に係る滅菌方法の流れを示すフローチャートである。第1実施形態に係る滅菌方法では、滅菌対象物を包装している包装材に予めオゾンガスを吸着させるためのオゾン吸着工程S300が設けられている。これに対して、オゾン注入工程S505においてチャンバー11の内部に注入されたオゾンガスが包装材に吸着する吸着量が、滅菌効率に大きく影響するものではないと予め想定される場合もあり得る。このような場合には、第1実施形態で採用してオゾン吸着工程S300と、それに伴う前減圧工程S200及び滅菌減圧工程S400とを採用しなくてもよい。
