[0002] The flue-cured tobacco room is a special room for the primary processing of mature flue-cured tobacco leaves, which mainly includes a loading room, heating equipment and ventilation system. During the curing, the heat source burns and heats in the furnace body. The heat emitted by the furnace body is blown into the curing room from the hot air inlet at the bottom of the furnace through the circulating fan. The hot air penetrates the tobacco leaves and returns to the heating room from the hot air return port. An internal circulation is formed between the loading room and the heating room, so that the heat is not lost and the energy saving effect is achieved.
[0003] During daily use, the applicant found that the volume of hot air in the smoking chamber gradually decreases from the hot air inlet to one end of the smoking chamber away from the hot air inlet, which will cause uneven baking of tobacco leaves in the smoking chamber and affect the baking quality.
