The water-containing garbage sent into the lower portion of the screen 54 is removed by the blade 53b of the screw 53 as described above.
While being agitated by the pins 60, the paper is conveyed above the screen 54. At this time, the water-containing garbage sticking to the inner surface of the screen 54, that is, the bent surface 54b, is scraped off by the pins 60, and the water splash from the small holes 54C is kept good. In particular, even when the hydrated garbage is a sticky substance, the small face 54C formed in the bent surface 54b is always in the eye because the bent surface 54b is formed in the vertical direction of the screen 54. It is open without clogging, and the drainage effect works effectively in the vertical direction. Further, the plurality of bent surfaces 54b can prevent the water-containing garbage from rotating together with the screw 53, and can efficiently move upward along the vertical bending surface 54b while being compressed by the water-containing garbage conveyed from below. Dewatered while being conveyed to.

Through these steps, the garbage is efficiently conveyed to the upper portion of the screen 54, while
The water that has flowed out of the small hole 54c into the casing 51 is discharged from the drain port 51b of the casing 51 into the external drain port. On the other hand, the dewatered garbage is discharged from the upper opening of the screen 54, is stirred by the stirring blade 66a of the screw cap 66 above the garbage, and is discharged from the discharge pipe 64 to an external garbage storage box (not shown). It is housed and processed inside.
