Compared to other heating methods, it can raise the temperature to the same level as the surface in a short time throughout the interior.
Far infrared heating can raise the temperature of the interior to the same level as the surface in a short time compared to other heating methods. Hot air heating and contact (conductive) heating are methods that heat the object by bringing heated air or the heat source itself into contact with it, and both have the same heat transfer method. Heat flow occurs due to the temperature difference between the hot air and the surface temperature of the object being heated, but only the conductive heat transfer from the surface to the interior occurs, resulting in relatively short time for the surface to reach the same temperature. Therefore, while the surface temperature rises, it takes a considerable amount of time for the temperature to increase throughout the interior. "Features" ○ Far infrared heating can heat the object with almost no temperature difference between the surface and the interior. ○ Compared to hot air heating, where heat gradually transfers from the surface to the interior, it can heat in a shorter time. ○ In the case of paint drying, phenomena such as foaming or cracking are less likely to occur. ○ In plastic processing, uniform heating prevents the occurrence of defective products. ○ For food and herbs, drying can be completed before the active ingredients, aroma, and flavor deteriorate. ○ Temperature distribution can be easily made uniform.

basic information
○ Far infrared heating generates a heat flow proportional to the fourth power of the difference between the heater temperature and the fourth power of the surface temperature of the heated object. ○ The calculation formula uses Stefan-Boltzmann's law. ○ Even after the heated object reaches the target temperature, the heater temperature remains high at its initial level. ○ The heat flow in far infrared heating remains almost constant from the beginning to the end of the heating process. ○ The heat flow received at the surface becomes the energy supplied to the interior, allowing for a rapid increase in temperature throughout the interior to match the surface temperature compared to other heating methods.
