[0043] In this embodiment, the design of the high-efficiency energy-saving drying device pays special attention to the transport efficiency and uniformity of the materials in the drying cylinder 2. The core component of the device is a rotating drying cylinder 2, which is uniformly arranged with spiral blades 24 on the inner wall circumference. The purpose of these spiral blades 24 is to transport materials along the axis of the drying cylinder 2 as the drying cylinder 2 rotates, ensuring the continuous movement of the materials during the drying process, thereby improving the heat exchange efficiency and drying speed.

[0044] Specifically, when the wet materials enter the drying cylinder 2 from the inlet 22, the spiral blades 24 start to work.
