Why is controlled bandwidth important?
The key to this process is that the bulk of the radiant energy bandwidth generated is in the far infrared range, with wavelengths ranging from approximately 3 to 7 microns. Water absorbs energy extremely efficiently at 3, 4.5 and 6 microns. By directing this energy spectrum at water-containing products, evaporative energy is targeted to the water within the product. Far infrared does not heat the air, therefore energy is transferred very efficiently to the organic matter.
