Drying Apparatus with Rotating Target for Uniform Airflow

The patent applies the dynamics principle by making the target object rotate during the drying process. The rotation mechanism ensures that all surfaces of the target object are dynamically exposed to the airflow from the drying heater, transforming a static drying process into a dynamic one. This rotation eliminates the uneven airflow contact problem by continuously changing the orientation of the target object relative to the airflow source, ensuring uniform drying across all surfaces.

The patent introduces a rotating holder or support structure as an intermediary between the drying heater and the target object. This intermediary mechanism facilitates the rotational movement of the target object, enabling uniform exposure to the drying environment. The holder acts as a mediator that translates the drying action into a uniform process across all surfaces of the target object.

The patent applies local quality by ensuring uniform distribution of thermal energy across all surfaces of the target object through rotation. Instead of concentrating heat in one area or having hot spots, the rotational movement distributes the thermal exposure evenly throughout the drying process. This uniform local heating prevents image distortion while maintaining high drying speed, as each portion of the target object receives consistent thermal treatment.

The dynamic rotation of the target object during heating ensures that no single area is exposed to excessive heat for prolonged periods. The continuous movement distributes the thermal load uniformly, preventing localized overheating that would cause image distortion. This dynamic thermal management maintains both high drying speed and image quality.
