The heat transfer in distiller's grains dryers primarily relies on convective heat transfer. During operation, the hot airflow generated by the heat source flows within the cylinder, making full contact with the distiller's grains. Through heat exchange between the airflow and the grains, the moisture is evaporated. So, how can we improve the heat utilization efficiency of the distiller's grains dryer?

On the one hand, it is necessary to strengthen the contact efficiency during the heat transfer process. By adjusting the structure of the baffles inside the cylinder, the distiller's grains form a uniform material curtain, increasing the contact area between the material and the hot airflow, allowing the heat to act more efficiently on each portion of the material. On the other hand, attention should be paid to the recycling of heat to reduce heat loss during the drying process. This can be achieved by rationally designing the sealing structure of the equipment to prevent the leakage of hot airflow, and by optimizing the ventilation system to promptly remove the evaporated water vapor, preventing humidity saturation inside the cylinder from affecting drying efficiency.

In short, understanding the heat transfer principles of the distiller's grains dryer and focusing on aspects such as sufficient contact and heat recycling are crucial for achieving stable and efficient operation of the distiller's grains dryer.
