The input hopper 210 is rotatably coupled to the upper and lower doors 211 so that the crushing process is performed in a closed state of the waste crusher 200, and the opening and closing doors 211 are selectively selected by the opening and closing cylinder 213. It is opened and closed. For example, the input hopper 210 opens and closes the door 211 before the medical waste is input, and when the medical waste is completed, the opening and closing door 211 is closed.

The crushing unit 220 crushes the medical waste to a certain size and discharges it to the lower portion. At this time, the shredding unit 220 is provided with a screen so that the medical waste is discharged only when it is crushed to a certain size or less.

And while the medical waste is shredded in the shredding unit 220, it is sterilized and sterilized by the sterilization processing unit 300.

The sterilization processing unit 300 is provided in the input hopper 210 so as to be located on the upper side of the crushing unit 220, and simultaneously generates steam and high frequency of 160° C. or higher into the input hopper 210 and the waste shredder 200 to be crushed. Medical waste is sterilized.

The sterilization processing unit 300 of the steam injection nozzle 320 and the input hopper 210 provided in the input hopper 210 to spray the steam generated in the steam generating member 310 into the input hopper 210 It includes a high-frequency oscillation member 330 that is provided in the lower portion to generate a high frequency into the interior of the input hopper 210 to which steam is injected. At this time, the steam generating member 310 and the steam injection nozzle 320 are provided with opening and closing valves, respectively.

Since the sterilization treatment unit 300 according to the present embodiment simultaneously sprays high temperature steam and high frequency with medical waste, steam penetrates into the waste, such as a needle or tube, which is difficult to sterilize, and the infiltrating steam acts as a medium for high frequency. This allows complete sterilization and sterilization.

In addition, the crushed waste that is crushed to a specific size or smaller in the waste crusher 200 is input to the transfer sterilization treatment unit 400 to be sterilized once more.

For example, the transfer sterilization processing unit 400 sterilizes the shredded waste by using hot air and high frequency while transporting the shredded waste discharged by being shredded by the waste shredder 200.

To this end, the transfer sterilization processing unit 400 transfers the sterilization case 410 connected to the lower end of the waste shredder 200, the hot air supply member 420 for sterilization inside the sterilization case 410, and transfer of the shredded waste. It includes a shredded waste transport member 430 for.

In addition, the transfer sterilization processing unit 400 further includes a steam nozzle 440 and a high frequency auxiliary oscillation member 450 so that sterilization is more effectively performed in the sterilization case 410. At this time, the steam nozzle 440 is supplied with hot steam from the steam generating member 310.
