NOVELTY - The utility model belongs to the technical field of drying device, specifically relates to a heating chamber structure for drying room, comprising a heating chamber, the heating chamber is provided with a heat pump, graphene heating module and a circulating fan. The utility model uses the heat pump and the graphene heating module in the heating chamber to heat the air, using the circulating fan to realize the flow of hot air, so as to obtain the hot air, so as to bake the tobacco leaf in the baking chamber, medicinal materials, edible fungi, agricultural products and so on. Therefore, the utility model uses the heat pump and graphene heating module to replace the traditional baking coal structure used by the drying room, which is more environment-friendly, which is good for realizing carbon and target.
