A double-jacketed steam sterilization pot includes a pot body, a first steam generator and a second steam generator. The pot system is composed of a first jacket and a second jacket, and a sterilization chamber is formed inside. The first jacket has a first interlayer, the second jacket has a second interlayer, the second jacket has at least one air duct for communicating the second interlayer and the sterilization chamber, the first The steam generator is connected to the first interlayer, and can be used to introduce general water from the outside and heat it to generate steam for input into the first interlayer, and the second steam generator is connected to the second interlayer and can be It is used to introduce pure water from the outside and heat it to generate steam for input into the second interlayer； thereby, it is possible to avoid contamination of the items to be sterilized and save the cost of consumables.一種雙夾套式蒸氣滅菌鍋包括一鍋體、一第一蒸氣產生器及一第二蒸氣產生器，該鍋體係由一第一夾套及一第二夾套組成，內部形成一滅菌室，該第一夾套之中具有一第一夾層，該第二夾套之中具有一第二夾層，該第二夾套具至少一導氣管供連通該第二夾層與該滅菌室，該第一蒸氣產生器係連接該第一夾層，且可供由外部導入一般水並對其加熱使產生蒸氣以供輸入該第一夾層之中，該第二蒸氣產生器係連接該第二夾層，且可供由外部導入純水並對其加熱使產生蒸氣以供輸入該第二夾層之中；藉此係可避免欲滅菌物品受污染以及可節省耗材成本。
