The present invention relates to a disinfection apparatus for disinfecting a disinfection tank in which a vertical frame and a horizontal frame are installed to raise and lower the storage frame so that both sides of the horizontal frame are positioned in left and right directions of the disinfection tank, A horizontal frame installed on an upper portion of the vertical frame is rotatable. A guide roller for guiding the vertical movement is attached to the side edge of the storage frame in which the seed bag is placed, so that the vertical frame is smoothly lifted. The upper guide is installed to prevent the seed bag contained in the storage frame from rising upward from the disinfection tank. An air supply device is installed on the upper side of the horizontal frame, and a line for supplying air from the rotated horizontal frame is twisted A seed sterilizing apparatus capable of preventing . In order to achieve the above object, the present invention provides a disinfection apparatus comprising: a disinfection tank (10) filled with hot water for seed disinfection； A storage frame (20) for storing a box (2) containing a bag (1) filled with a seed for disinfection； An ascending / descending means installed on the disinfection tank (10) for ascending / descending the storage frame (20) in which the seed bag (1) is stored up and down； Hot water supply means connected to the disinfecting tank 10 to supply and circulate hot water into the disinfecting tank 10； And a control unit (60) electrically connected to the disinfecting tank (10) to automatically control the elevating and lowering of the accommodating frame (20) through hot water supply and elevating means through hot water supply means, A vertical frame 30 installed at an upper portion of the vertical frame 30 and installed at both ends of the disinfection tank 10 so as to be automatically or manually operated under the control of the controller 60 And a horizontal frame 31 on which the horizontal frame 31 is mou
