The present invention provides a low-temperature liquid sterilization device including a container and a sterilization device. The container is suitable for containing a low-temperature liquid whose temperature is lower than room temperature. The sterilizing device is detachably installed in the container. The sterilizing device includes a light-transmissive housing, a light-emitting module, a handle, and a power supply module. The light-transmissive shell is suitable for extending into the container and immersing in the low-temperature liquid, and defining a containing space isolated from the low-temperature fluid. The light-emitting module is disposed in the accommodating space, and can control the emission of ultraviolet light that penetrates the transparent casing and irradiates the low-temperature liquid. The grip is mounted on the light-transmissive casing and is located outside the container. The power supply module is disposed on the handle and is electrically connected to the light emitting module to provide power to the light emitting module.本創作提供一種低溫液體殺菌設備，包含一容器及一殺菌裝置。該容器適用於容裝一低溫液體，該低溫液體的溫度小於室溫。該殺菌裝置可分離地裝設於該容器，該殺菌裝置包括一透光殼體、一發光模組、一握把及一供電模組。該透光殼體適用於伸入該容器並浸入該低溫液體中，並界定出一與該低溫流體隔離的容置空間。該發光模組設置於該容置空間，並能受控發出穿透該透光殼體而照射於低溫液體的紫外光。該握把裝設於該透光殼體且位於該容器之外。該供電模組設置於該握把並與該發光模組電連接，以提供電力給該發光模組。
