Description
Technical Field
[0001] The utility model relates to the technical field of uniformly heated baking rooms, in particular to a uniformly heated baking room with bidirectional circulating air. Background Art
[0002] The traditional tobacco curing room has unidirectional airflow. During the entire 7-10 day tobacco curing process, the wind flow direction is fixed, which leads to uneven temperature distribution in the whole curing room, uneven wind flow and wind pressure, and then uneven temperature and humidity in the whole curing room, which easily causes a large difference in temperature and humidity between the upper and lower layers. As a result, during the whole tobacco leaf curing process, the demand stage and maturity of each layer of tobacco leaves are inconsistent, making the quality of the cured tobacco leaves difficult to control and forming local waste tobacco. The above reasons also lead to the overall extension of the tobacco leaf curing time, resulting in a waste of energy and working hours. Therefore, it is urgently necessary to set up a curing room that can control the two wind flow directions of the circulating wind in the tobacco curing room to improve and enhance the quality of the cured tobacco and shorten the tobacco curing time to meet the needs of the curing room.
