NOVELTY - The utility model belongs to the technical field of tobacco baking, specifically relates to a heating chamber structure of tobacco curing barn, comprising a heating chamber main body, a circulating fan platen and a graphene heating module, the circulating fan platen divides the inner space of the heating chamber main body into an upper chamber and a lower chamber, the circulating fan platen is provided with a passage for connecting the upper chamber and the lower chamber, the graphene heating module is installed in the upper chamber and/or the lower chamber. In the utility model, using graphene heating module to replace the traditional coal burning heat, which is more environment-friendly, which is good for realizing carbon and target. and the graphene heating module can select the mounting graphene of the heating module according to the requirement of the air flow rising type curing barn/air flow descending type curing barn, it is very convenient to improve the structure of the existing curing barn, and the improvement cost is low. In addition, the utility model is not only suitable for baking tobacco leaf, but also suitable for agricultural product, marine product, drying of medicinal materials, industrial product and so on, wide application.
