The present invention relates to a feeder sterilizer, formed with a vacuum chamber inside a housing, and the seating portion are sterilized object is placed on one side, it is installed in the vertical direction on the inner side of the housing at one side between the part and the guide member and the guide member passing through the mounting portion at one side seating above, and the bracket including a pair of cushioning members are interposed respectively between the housing and the seating portion, the one side connected to one side of the bracket and, oscillation means for oscillating the bracket and, at one side is disposed within a side of the housing is provided on one side of the sterile liquid ejecting portion and the housing such that spread by spraying the sterilizing liquid into the vacuum chamber, the vacuum chamber but as to discharge the air to the outside to form the vacuum chamber in a vacuum state includes a dust collecting section for collecting the foreign substances in the vacuum chamber, wherein the vibration means includes a rotating shaft rotatably mounted to the lower side of the bracket, an outer surface of the rotary shaft coupled eccentrically, the plurality is eccentrically coupled to each other hand, if while rotating accompanied, as the rotary shaft rotates in contact with the lower surface side of the bracket at one side of the cam member and the rotary shaft for pressing upward the lower surface of the bracket connects to and provides a tributary sterilizer comprising the rotational force providing means for providing a rotating force to the rotating shaft. According to the present invention as described above, the sterilized object is seated under a vacuum atmosphere bracket vibration and at the same time by spraying a fine sterilizing liquid into the vacuum chamber sterilized particles are adhered to the sterilizing object to be vibration by sterilization the sterilizing object as well as the stripping efficiency of the fine dust
