Gas infrared drying principle: 

The heat generated by the combustion of gas can raise the temperature of the object to 800- 1000 degrees, thereby radiating intense infrared rays with a corresponding wavelength of 2-4 microns. Infrared is invisible light that travels straight at the speed of light and has a certain penetration. After infrared rays are absorbed by objects, they can be quickly converted into heat energy, so there is a strong heating effect. When the infrared wavelength is consistent with the absorption wavelength of the heated object, the heated object absorbs infrared rays. At this time, the molecules and atoms inside the object resonate to produce strong vibration and rotation. The vibration and rotation raise the temperature of the object and achieve the purpose of heating. Thus, infrared rays can be used for rapid heating.
 

Blue torch infrared equipment energy-saving features:

Because the material is a network of three-dimensional structure of holes, each hole is irregular, coupled with elasticity, so it can effectively avoid airflow noise. At the same time, due to the completely premixed combustion mode, the combustion is sufficient and the excess air coefficient is small, so the thermal efficiency is relatively high and the gas can be saved. Moreover, since the resistance of the material is small, it does not require a high-power fan, and the resulting electricity bill can be saved. nbsp;

 Due to the use of high temperature resistant alloy material sheets as heating elements and combustion media, and the thermal inertia of the material is small, so it can quickly heat up and cool down, that is, after ignition, its temperature can rise from normal temperature to working temperature within a few seconds. Similarly, after stopping working, it can also cool from working temperature to normal temperature within a few seconds. This is very beneficial to prevent materials from being damaged due to excessive heating, especially to completely avoid flammable materials such as paper, The fabric caught fire due to overheating when encountering extraordinary accidents such as power failure.





Blue torch infrared drying working principle:

I. Principle of radiation 

Any object will radiate energy to the outside world. According to Boltzmann's law, the relationship between the energy radiated by an object and its temperature follows the following formula:  E=σ T4 . It can be seen that the relationship between the energy radiated by an object and its temperature is fourth-power, that is, the higher the temperature of the object, the greater the energy radiated to the outside world. nbsp; The heat generated by combustion of gas can raise the temperature of the object to 800-1000℃, thereby radiating intense infrared rays with a wavelength of 2-4 m. nbsp;

Second, infrared heating (drying) principle
Infrared is invisible light that travels straight at the speed of light and has a certain penetration. After infrared rays are absorbed by objects, they can be quickly converted into heat energy, which has a strong heating effect. Different materials have different absorption rates for infrared rays. Water is one of the substances that can absorb infrared rays strongly. After water absorbs infrared rays, its temperature rises rapidly and evaporates. This is the principle of infrared drying. Infrared heating is several times faster than conventional hot air heating, so infrared can be used for field combinations that require rapid heating and drying. nbsp;
