본 발명의 과제는, 건조품의 컨태미네이션, 입자 형상의 변형, 입도 분포의 변화를 방지하는 것에 있다. 분리롤의 외주에 권회되어 있는 무단상(無端狀)의 한 쌍의 분리 여과포 사이에 피처리물을 공급해서 압착함과 아울러, 상기 분리롤의 외주면에 형성된 통기공으로부터 통기되는 통기 가스에 의해 탈수하는 고액 분리 장치와, 상기 고액 분리 장치의 후단에 횡형 회전식 건조기를 구비하고, 캐리어 가스를 상기 건조기의 회전통 내에, 피처리물의 반송 방향과 동일한 방향의 병류(竝流)로 유통시키도록 했다. An object of the present invention is to prevent the contamination of a dried product, the deformation of particles, and a change of particle size distribution. The system includes: a solid-liquid separator in which a processing material is supplied between a pair of endless separation filter cloths wound around an outer periphery of a separation roll, and is dehydrated by being squeezed therebetween and also by ventilation gas passing from a ventilation port formed in an outer peripheral surface of the separation roll; and a horizontal rotary dryer provided on a subsequent stage of the solid-liquid separator, wherein carrier gas is made to flow in a rotating shell of the dryer in a cocurrent manner in the same direction as a conveyance direction of the processing material.
