A double-jacketed energy-saving steam sterilization pot includes a pot body, a steam generator, a first steam duct, and a second steam duct. The pot body is composed of a first jacket and a second jacket, and is formed inside. A sterilization chamber, the first jacket has a first jacket, the second jacket has a second jacket, the steam generator includes a container and a spiral tube, the container can heat general water to form steam and then Into the first interlayer, the spiral tube is arranged in the container for introducing pure water, and then heated by the high-temperature steam in the container to form pure water vapor, and then sent to the second interlayer, the second The pure water vapor of the interlayer can be sent into the sterilization chamber through a first vapor conduit； thereby, the contamination of the items to be sterilized can be avoided, and consumables and energy costs can be saved.一種雙夾套節能蒸氣滅菌鍋，包括一鍋體、一蒸氣產生器、一第一蒸氣導管及一第二蒸氣導管，該鍋體由一第一夾套及一第二夾套組成，內部形成一滅菌室，該第一夾套中具有一第一夾層，該第二夾套中具有一第二夾層，該蒸氣產生器包含一容器及一螺旋管，該容器可將一般水加熱形成蒸氣然後送入該第一夾層中，該螺旋管係設於該容器中可供導入純水，然後藉由該容器中之高溫蒸氣將其加熱形成純水蒸氣後再送入該第二夾層，該第二夾層之純水蒸氣則可透過一第一蒸氣導管送入該滅菌室之中；藉此係可避免欲滅菌物品受污染以及可節省耗材與能源成本。
