[0002] Far-infrared drying equipment refers to drying equipment that uses far-infrared rays as the main medium to convert electrical energy into thermal energy, so that the molecules inside the object absorb the far-infrared radiation energy after being radiated by the far-infrared rays, thereby directly converting it into heat.

[0003] The prior art has disclosed a technical solution for drying equipment. The Chinese patent application number is: A heating mechanism for a dryer. The application date is December 17, 2021. The name of the invention is: Tooling for detecting hole position and deformation. The application discloses a heating mechanism for a dryer, including a heating tank, a leg welded to the lower part of the heating tank, a heat pump housing is provided at the lower part of the heating tank, a heat pump device is provided inside the heat pump housing, a water receiving box is provided at the lower part of the heat pump housing, an air inlet pipe and an air outlet pipe are provided on the left side of the heat pump housing, and the inlet The upper ends of the air duct and the air outlet duct are respectively connected to the heating tank. The heat pump device includes a cooler. The utility model has a heating tank for placing raw materials therein for heating. The heat pump device includes a cooler and a heat exchanger. The cooler is cooled by the heat pump system compressor and the internal refrigerant, and the heat exchanger is used for heating. The hot air is introduced into the heating tank for drying, and the humid hot air is blown to the cooler by the fan, so that the humid hot air is condensed, and the moisture is removed and then blown to the heat exchanger again. The heated air enters the interior of the heating tank to form an air cycle, thereby achieving the purpose of energy saving.
