Description

technical field [0001] The invention relates to the technical field of far-infrared heating, in particular to a far-infrared planar heating element and a production method thereof. Background technique [0002] Drying devices are used in agricultural production, Chinese herbal medicine production, civil heating and medical physiotherapy and other fields. After the grain and Chinese medicinal materials are harvested, they need to be dried for storage and rolling. In order to complete the drying process as soon as possible, people use drying equipment for processing. The drying equipment in the prior art adopts an upright baking oven, which uses coal, diesel oil or resistance wire to generate heat as a heat source. Its disadvantages are: a baking oven using coal, diesel or electricity as a heat source will consume a lot of fuel, and the production cost is high; the heating efficiency of the resistance is low, wasting electric energy; and the conventional baking device will c...
