Basics of Drying - Good to know
Infrared Drying
- Drying with infrared readiators the water is evaporated using the radiated heat.
- For most infrared dryers tempratures of 250-300 °C are used. That is higher than the flash point of paper.
- The ideal absorbtion of energy take playe with a IR wave length of 3µm.
Air Drying
- The water in the ink is evaporated by the air flowing over the board and is evacuated from the printing area.
- Heating the air is used only to accelerate this process
- With 120 °C air temprature, the maximum drying efficiency is achieved; higher tempratures do not accelerate the process very significantly.
- The air dryer process is mor efficient. It requires lower temperatures so a lower energy consumption thanan IR dryer.
