The invention discloses a rotary type electron beam sterilization device. The rotary type electron beam sterilization device comprises a rack, a first rotary disc, a second rotary disc and an electronbeam illuminating mechanism, wherein the first rotary disc and the second rotary disc are rotatably arranged on the rack around a first shaft, and the electron beam illuminating mechanism is arrangedon the rack. A height difference H is formed by the first rotary disc and the second rotary disc. Each bottle body comprises a first part and a second part, wherein each first part and the corresponding second part are formed by equally dividing the corresponding bottle body through the axis of the corresponding bottle body in the radial direction. When the bottle bodies are located on the firstrotary disc, the first parts are directly illuminated. When the bottle bodies are located on the second rotary disc, the second parts are directly illuminated. The device further comprises one or morelifting conveying mechanisms and one or more transitional conveying mechanisms, wherein the lifting conveying mechanisms and the transitional conveying mechanisms are arranged on the rack. The lifting conveying mechanisms and the transitional conveying mechanisms are used for conveying the bottle bodies on the first rotary disc into the second rotary disc. The total height of each bottle body ascended or descended by the lifting conveying mechanisms is H. The device is simple in structure, and the bottle bodies can be illuminated in all directions for sterilization.
