MICROWAVE DRYERS FOR PRINTING SYSTEMS THAT UTILIZE ELECTROMAGNETIC AND RADIATIVE HEATING
摘要:
Microwave dryers and a method of fabricating microwave dryers are disclosed. The microwave dryers include a microwave source that generates electromagnetic energy to dry a wet colorant applied to a continuous-form print medium. The microwave dryers further include a microwave waveguide electromagnetically coupled to the microwave source that transports the electromagnetic energy between a first end and a second end. The microwave waveguide includes a passageway that is sized to pass the continuous-form print medium through the microwave waveguide. The microwave dryer further includes a plurality of microwave absorbing elements within the microwave waveguide that absorb the electromagnetic energy and heat the wet colorant.
