Far-infrared heating method of smokeless grill

Scientific experiments have proved that no heat transfer medium is required for far infrared heating. It has a strong penetrating ability. In this way, compared with conventional conduction methods, far-infrared heating has direct heat transfer, high production heat efficiency, sanitation and environmental protection, sterilization and disinfection, fast, clean, hygienic, good quality, and good taste. . Great energy saving, simple manufacturing, easy promotion and other advantages. Let me give you a brief introduction to the infrared heating method of the smokeless grill.

　　 There are two far infrared heating methods for smokeless barbecue grills: one is gas far infrared heating method; the other is electric heating tube far infrared heating method. Only the energy is different, and the far infrared rays produced are all the same special substance. Far infrared itself is an electromagnetic wave that transmits energy.

　　 is outside the red spectrum, between the red and invisible spectrum, so it is called far infrared. The wavelength is between 0.47-400 microns. The heat transfer form of far-infrared is radiation transfer heat energy, and electromagnetic waves transfer energy. When the far-infrared rays are irradiated to the heated object, a small part of the rays are reflected back, and most of them penetrate into the heated object.

Since far-infrared is a kind of energy, when the emitted far-infrared wavelength is the same as the absorption wavelength of the heated object, the molecules or atoms in the heated object absorb the far-infrared energy, generate strong vibration and cause the molecules and atoms inside the object Resonance occurs. The high-speed friction between the molecules or atoms of the object generates heat to increase its temperature, thereby achieving the purpose of heating.
