クリーンは粗目のものを用いるは勿論である。That is, according to the present invention, the washing of the screen residue and the pressing dehydration are simultaneously performed, and a conventional washing pond or the like is not required. Further, in the present invention, since the screen drum is rotatably supported and the washing nozzle is provided around the rotation, even if the screen drum is clogged during washing or squeezing and dehydrating, it can be washed and regenerated. And continuous operation is possible. Needless to say, a coarse screen is used at the entrance of the screen drum.
