Infrared drying is a method of drying materials or products using infrared radiation. Infrared radiation is a form of electromagnetic radiation with wavelengths longer than visible light but shorter than radio waves.
Infrared drying works by emitting infrared radiation onto the material or product to be dried. This radiation is absorbed by the surface of the material, causing its molecules to vibrate and generate heat. This heat then evaporates the moisture within the material, resulting in drying.
There are several advantages to using infrared drying:
Faster Drying: Infrared radiation can penetrate the surface of the material, heating it from within and leading to faster drying compared to conventional methods.
Energy Efficiency: Infrared drying can be more energy-efficient compared to other drying methods because it directly heats the material rather than heating the surrounding air.
Uniform Drying: Infrared radiation can be controlled and directed precisely, allowing for more uniform drying across the material’s surface.
Reduced Contamination: Since infrared drying doesn’t rely on circulating air, there’s less risk of contamination from dust or other airborne particles.
