What you can do to increase the drying performance of infrared radiation is to experiment with the combination of infrared radiation with hot air or ambient air, especially if you are dealing with water-based coatings that require more energy to dry than solvent-based chemistry. Controlled airflow is not only necessary for the following ventilation and exhaust, it can also improve the drying of coatings. In an infrared/air dryer, infrared radiation guarantees energy for heating and air removes water vapor. Hybrid dryers are the more efficient for drying coatings, finishes, inks and glues on sensitive substrates such as paper and plastic-coated film, where excessive heat can destroy the painting or the material.

Infrared/air dryers come in a variety of configurations. To begin with, infrared heaters can be used as pre-dryers before hot air dryers. The infrared pre-dryer rapidly increases the temperature of the product, starting the desiccation process before the product enters the hot air dryer, which in turn leads to a higher drying speed. This drying process is effective on textile fabric finishing lines and paper coating lines.
Infrared radiation can still be introduced between the nozzles of the hot air dryer. Often manufacturers have had to delay the coating sections of water-based coatings in order to increase the residence time of the product in the hot air dryer. As an alternative, they've switched to longer dryers. One conclusion is lower productivity; the other takes up more production space. By installing infrared heaters between the hot air nozzles, the product receives auxiliary energy to facilitate drying at higher speeds in the existing dryer industrial infrared heating systems.

Ambient or heated air can still be routed to the product between the infrared heater modules in the dryer and then discharged. In this configuration, because the coating or saturating agent eats the infrared energy and the water escapes, the air cleans the coating plane, taking away water vapor and improving the drying without creating bubbles on the coating or damaging the substrate.
Finally, what can you do with infrared to improve the drying process? First, choose a favorable energy key for your application. Two, provide good temperature control. Third, make sure that your infrared heaters are properly designed into the infrared dryer. Fourth, use air with infrared radiation. After all, keep in mind that infrared is an excellent method of drying almost all foods, but the infrared heat you use must be served by an efficiently designed system designed to meet the specific drying requirements of your product.
