Pigment Ink Drying Section with Pulsed Electromagnetic Heating

The patent applies periodic action by generating electromagnetic waves in a pulsed manner rather than continuously. The control unit controls the electromagnetic wave generation unit to generate electromagnetic waves periodically, creating intervals of high-intensity radiation followed by rest periods. This allows the medium to be dried efficiently during the pulse intervals while preventing excessive heat accumulation that would cause thermal denaturation during the rest intervals.

The patent implements dynamics by making the electromagnetic wave generation controllable and adjustable. The control unit dynamically adjusts the generation timing, duration, and intensity of electromagnetic waves based on the drying requirements. This dynamic control enables optimization of drying efficiency while preventing thermal damage by adapting the radiation parameters to the specific state of the medium being dried.

The patent uses periodic action to alternate between high-intensity electromagnetic wave generation and rest periods. During the generation intervals, drying efficiency is maximized through high-intensity radiation. During the rest intervals, the medium cools down slightly, preventing cumulative thermal damage. This periodic cycle maintains both high drying efficiency and medium quality.

The patent maintains continuity of useful action by ensuring that the periodic electromagnetic wave generation continues throughout the drying process without interruption. The control unit manages multiple pulse cycles continuously, ensuring that drying action is consistently applied while the periodic nature prevents thermal damage. This continuous periodic action achieves both high productivity and quality preservation.
