Heating and Evaporization
Water readily absorbs infrared radiant energy at
3, 4.5 and 6 microns wavelength. The energy delivered by CDT’s flameless catalytic infrared
system perfectly targets the moisture in the substrate.
Gone are the detrimental effects of convection
heating (skinning over, high air velocities, high heat differentials in the product).
Gone are the moisture gradients and slow drying times associated with conduction heating.
The more moisture at a point in the product, the greater the absorption of infrared energy.
This reduces stresses and improves both drying times and drying uniformity.
Highly efficient and tightly-controlled
infrared radiant energy is delivered to the product as it travels along a purpose-built conveyor
engineered to uniformly expose the product to the radiant energy.
Equipment costs are on a par with conventional
heating systems. However, since drying / heating times can be greatly reduced using flameless
catalytic infrared energy, smaller equipment or more throughput (or both) often result from
using a CDT catalytic infrared system.
