Description

Technical Field

[0001] This application belongs to the technical field of tobacco leaf storage, and specifically relates to a flue-cured tobacco leaf storage device. Background Art

[0002] Flue-cured tobacco leaves are the leaves picked from high-quality tobacco varieties and are products after baking, processing, etc. They are widely used in making tobacco products such as cigarettes and pipe tobacco. As the core raw material of the tobacco industry, flue-cured tobacco leaves have unique flavors, colors, and tastes. And after scientific treatment and processing, the negative impacts on human health have also been controlled to a certain extent. In order to ensure the quality and flavor of tobacco leaves, a series of treatments are required after picking, such as sorting, baking, fermentation, etc. In addition, the storage method also has a great impact on the quality of tobacco leaves. Usually, it needs to be stored under appropriate temperature and humidity conditions to ensure that its quality and flavor are not lost.

[0003] For example, a utility model patent with the publication number CN221520387U discloses a flue-cured tobacco leaf storage device, which relates to the technical field of tobacco leaf storage. The device includes a box body, a chamber is opened inside the box body, and an internal circulation dehumidification component is fixedly arranged on one side. A protective net is fixedly arranged on the inner wall of the chamber. Above the protective net is a tobacco leaf placement component, and below is a drying component. A humidity detection component is arranged on the inner wall of one side of the chamber. Through the mutual cooperation of the tobacco leaf placement component, the drying component, and the internal circulation dehumidification component of the present utility model, the hot air released by the drying component can fully circulate in the chamber, and the stored flue-cured tobacco leaves can be fixed through the tobacco leaf placement component, so as to better dry the flue-cured tobacco leaves. At the same time, since the flue-cured tobacco leaves are put into the box body by pulling, if the stored flue-cured tobacco leaves need to be taken out, only the lower partition board needs to be pulled out, reducing the loss of hot air and the increase of humidity in the box body, and greatly improving the practicability of the device.

[0004] However, it is found in the actual use process that: the device clamps and fixes the flue-cured tobacco leaves through the lower partition board and the upper partition board, so as to facilitate the subsequent drying operation of the flue-cured tobacco leaves;

[0005] However, only partial second through slots are opened between the lower partition board and the upper partition board of the device. Although it is convenient for the circulation of hot gas, it also brings some problems. For example, the upper and lower partition boards will contact the flue-cured tobacco leaves, and this contact forms a barrier, making the hot gas unable to fully exchange heat with the partition board body in the contact part of the tobacco leaves, resulting in the drying efficiency being affected. Specifically, due to the shielding of the partition board, the hot gas is difficult to act uniformly on each part of the tobacco leaves. Especially in the area where the tobacco leaves contact the partition board, there may be incomplete or uneven drying phenomena. Therefore, a flue-cured tobacco leaf storage device is provided.
