[0019] 1. Through the setting of ventilation mechanism one, combined with ventilation mechanism two, the two form a wind reduction and concentration increase combination, and the device is provided with three such combinations. The generation of wind usually consumes a certain amount of energy. Reducing the wind intensity or air volume can reduce the energy required for the operation of the device, thereby achieving energy-saving effects. Large air volume often brings greater noise. Reducing the wind can reduce the noise level during the operation of the dryer and improve the working environment. Especially for fine granular or powdery materials, excessive wind can cause the material to fly, resulting in material loss and environmental pollution. For example, when drying fine chemical raw materials or pharmaceutical powders, reducing the wind can ensure that the materials are effectively processed in the device and improve the utilization rate of the materials.

[0020] 2. The setting of the return air elbow makes it easier to make the air run in a reciprocating manner and increase the concentration of the hot air. By increasing the concentration in the dryer, the heat transfer efficiency can be improved. The concentration technology can reduce the exhaust volume and increase the exhaust gas concentration, thereby reducing energy consumption. BRIEF DESCRIPTION OF THE DRAWINGS
