PROBLEM TO BE SOLVED: To enhance sterilization effect and reduce time until starting a sterilization process, even when a sterilization which has to be condensed is used for the sterilization process.SOLUTION: A sterilization unit 100 performs sterilization of a sterilization object using a sterilization agent. An arithmetic processing part 201 condenses the sterilization agent at a condensation furnace 235, and stores the sterilization agent which was condensed at the condensation furnace in advance, in a condensed sterilization agent pool part 237. Then the arithmetic processing part uses the sterilization agent stored in the condensed sterilization agent pool part, and performs the sterilization process for sterilization of the sterilization object in a sterilization chamber 219 during the sterilization process.COPYRIGHT: (C)2015,JPO&INPIT【課題】滅菌処理を行う際に、濃縮する必要のある滅菌剤を用いる場合であっても、滅菌効果を高めて、かつ滅菌処理を開始するまでの時間を短くする。【解決手段】滅菌装置100は、滅菌剤によって滅菌対象物を滅菌する。演算処理部201は濃縮炉235で滅菌剤を濃縮して、予め濃縮炉で濃縮された滅菌剤を濃縮済み滅菌剤プール部237に貯留する。そして、演算処理部は、滅菌処理の際、濃縮済み滅菌剤プール部に貯留された滅菌剤を用いて、滅菌室219で滅菌対象物を滅菌する滅菌処理を行う。【選択図】図2A
