[0002] With the increasing global demand for energy and growing concern about the environmental impacts of traditional fossil fuels (such as greenhouse gas emissions and air pollution), the development and utilization of renewable energy are receiving increasing attention. Biomass energy, as a renewable energy source, comes from a wide range of sources, including various organic wastes such as crop straw and forestry residues.

[0003] Currently, pneumatic dryers are commonly used to dry biomass materials such as straw and wood scraps. These dryers simultaneously feed biomass particles and hot air into a drying tube. The hot air flows through the tube at a high velocity, causing the material to suspend in the airflow. This rapid flow of hot air allows for sufficient heat exchange between the material and the hot air, rapidly evaporating the moisture and achieving the desired drying effect.
