摘要： 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.

摘要： Provided is an indirectly heating rotary dryer which has achieved enhanced energy-saving performance by reducing heating tubes non-contacting with material to be dried and reducing power required for rotation even when a hold up ratio is increased.
Specifically provided is an indirectly heating rotary dryer having four partition walls 16 extended respectively along an shaft center C in an inner space of a rotating shell 10 at angle intervals of 90 degrees in the vertical and horizontal directions. The four partition walls 16 partition the inner space of the rotating shell 10 at a lateral section of the rotating shell 10 into four approximately-sector-shaped small spaces K respectively extended along the shaft center C. Heating tubes 11 are aligned in the rotating shell 10 in three lines extended respectively in parallel to the shaft center C of the rotating shell 10. The heat tubes 11 heat and dry the material H to be dried by supplying heated steam to the heating tubes 11 and performing heat exchange with the material H to be dried in the rotating shell 10.摘要翻译： 提供了一种间接加热旋转干燥器，其通过减少与待干燥材料不接触的加热管，并且即使当保持率增加时也降低旋转所需的功率，从而提高了节能性能。 具体地提供了一种间接加热旋转干燥器，其具有在旋转壳体10的内部空间中沿垂直方向和水平方向以90度的角度间隔沿轴心C分别延伸的四个分隔壁16。 四个分隔壁16将旋转壳体10的侧部的旋转壳体10的内部空间分隔成分别沿着轴心C延伸的四个大致扇形的小空间K.加热管11在旋转壳体 10根三根线分别平行于旋转壳10的轴心C延伸。热管11通过向加热管11供应加热的蒸汽并与材料H进行热交换来加热和干燥要干燥的材料H 在旋转壳体10中被干燥。
