The core working principle of the High-Quality Dryers is to utilize gas fluidization technology to induce a fluidized state of suspension and boiling in wet materials under the action of airflow, thereby achieving efficient heat and mass transfer between the material and the hot airflow. The specific process is as follows: Wet material is continuously fed into the fluidization section of the dryer by the feeding device. Clean hot airflow, after filtration and heating, is uniformly introduced from the gas distribution plate at the bottom of the dryer. When the airflow velocity reaches the critical fluidization velocity, the material particles are lifted by the airflow, overcoming their own gravity to form a suspended state. At this point, the material particles are no longer fixedly piled up, but have fluidity like a fluid, allowing for sufficient contact with the hot airflow and vigorous mixing within the fluidization section, greatly increasing the heat and mass transfer area.Industr…
