Drying device

The invention provides a drying device. The drying device is provided with a shell, multiple rotary shafts and multiple blades. A pitching opening for pitching of disposed objects is formed in the front portion side of the shell, and a discharging opening for discharging of the heated and dried disposed objects is formed in the rear portion side of the shell; the rotary shafts are configured to be capable of rotating in the shell; and the blades protrude towards the radial outer side from the peripheral surfaces of the rotary shafts, multiple stages of the blades are arranged in the axis direction of the rotary shafts at intervals, every two adjacent rotary shafts rotate in the same direction, and the blades form a wedge shape with a narrower width as heading toward the front portion of the rotating direction when viewed from the radial outer side. 本发明提供种干燥装置，该干燥装置具备：外壳，其在前部侧形成有投入被处理物的投入口、在后部侧形成有排出加热干燥处理后的被处理物的排出口；多根旋转轴，其设为能够在外壳的内部进行旋转；以及多个叶片，它们从旋转轴的外周面向径向外侧突出，并且在旋转轴的轴线方向上隔开间隔地配置有多级，相邻的旋转轴彼此向同方向旋转，多个叶片形成为在从径向
