[0002] Cigar refers to the use of sun-cured tobacco and its reconstituted sheet as an outer wrapper, and the use of sun-cured tobacco leaves with cigar flavor as the main material for the core, and the use of tobacco products with a distinct cigar flavor in the smoke. The existing cigar leaf, the structure of the cigar product from inside to outside is core leaf, inner wrapper, and outer wrapper. Before manufacturing the cigar, the tobacco leaf must be naturally aged and fermented, so that the inherent aroma quality can be fully revealed and played, and the use value can be improved. The existing natural aging method is to age the tobacco leaf, and to store the re-dried tobacco leaf in a warehouse with good storage conditions for a certain period of time, to improve the quality of the tobacco leaf by means of slow chemical reaction inside the tobacco leaf. The existing natural aging time is long, generally about two years. Not only a large amount of storage is needed for aging, but also a large amount of funds is occupied, and the market response speed is slow.

[0033] It should be noted that the exhaust port 3 is arranged on the side of the cigar holder 4 away from the return air pipe 2, so that when the exhaust is performed, the exhaust port 3 and the return air pipe 2 are respectively located at the two ends of the cigar holder 4, and the ratio of the exhaust amount of the exhaust port 3 to the return air amount of the return air pipe 2 is close to 1:1, at this time, the airflow at the two ends of the cigar holder 4 is almost the same, and the stability of the airflow in the entire aging chamber 6 is stronger.

[0040] Moreover, the exhaust fan is arranged in the exhaust port 3, in the application, the number of layers of the cigar holder 4 is at least two, and at least one exhaust port 3 is arranged on the height of each layer of the cigar holder 4, that is, at least one exhaust port 3 is arranged on the height of each layer of the cigar holder 4, and the exhaust port 3 is used for preferentially exhausting the air of the layer of the cigar holder 4.

[0041] Generally, seven cigar holders 4 are arranged in the whole aging chamber 6, each cigar holder 4 is divided into three layers, and two layers of cigar tobacco boxes can be placed in each layer, preferably, six exhaust ports 3 are arranged on the side wall of the aging chamber 6, and one exhaust port 3 is arranged on the left and right sides of the wall of each layer of the cigar holder 4.

[0045] Embodiment two, still as shown in Figs. 1 to 4 Embodiment two, still as shown in

[0046] That is, the fresh air outlet 17 can change the air outlet direction under the adjustment of the air direction regulator, and the air outlet direction can be horizontal air outlet at the highest and can be inclined downward by 45° for air outlet at the lowest. It has been proved through multiple experiments that, during the early stage of cigar aging in the cigar holder 4 and the period of maximum moisture release, the inclined downward air outlet of the fresh air outlet 17 can effectively promote the uniform distribution of fresh air in the aging chamber, reduce the area of the low-speed zone, high-temperature zone and high-humidity zone in the aging chamber, and reduce the influence of the opening process of the exhaust fan on the flow field and temperature and humidity field of the aging chamber, thereby promoting the uniformity of the flow field and temperature and humidity field of the aging chamber.

[0047] Moreover, the inclined adjustment of the fresh air outlet 17 is used to avoid the height of the exhaust outlet and avoid the direct exhaust of fresh air by the exhaust fan during the exhaust process, thereby improving the regulation and control ability of the constant temperature and humidity machine on the flow field and temperature and humidity field and avoiding resource waste.

[0048] It should be noted that the air direction regulator has many, which can be individually controlled and adjusted by the controller, and the orientations of the fresh air outlets 17 on the first fresh air pipe 11 and the second fresh air pipe 12 can also be different, and even the orientations of the multiple fresh air outlets 17 on the first fresh air pipe 11 are different, forming the relative flow of the air directions on both sides of the cigar holder 4 in the aging chamber 6, and further adjusting the air unevenness in the entire aging chamber 6.
