摘要： Provided is an indirectly heated 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 heated rotary dryer having four partition walls extended respectively along a shaft center in an inner space of a rotating shell at angle intervals of 90 degrees in the vertical and horizontal directions. The four partition walls partition the inner space of the rotating shell at a lateral section of the rotating shell into four approximately-sector-shaped small spaces respectively extended along the shaft center. Heating tubes are aligned in the rotating shell in three lines extended respectively in parallel to the shaft center of the rotating shell. The heat tubes heat and dry the material to be dried by supplying heated steam to the heating tubes and performing heat exchange with the material to be dried in the rotating shell.

摘要翻译： 提供了一种间接加热旋转干燥机，其通过减少与待干燥材料不接触的加热管，并且即使在保持比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，其具有在垂直和水平方向上以90度的角度间隔分别沿旋转壳体的内部空间中的轴心延伸的四个分隔壁。 四个分隔壁在旋转壳体的侧面部分将旋转壳体的内部空间分成四个分别沿轴心延伸的大致扇形的小空间。 加热管在旋转壳体中对准，三根分别平行于旋转壳体的轴心延伸。 热管通过将加热的蒸汽供给到加热管中并加热并干燥待干燥的材料，并与旋转壳中待干燥的材料进行热交换。
