Description

Technical Field

[0001] This utility model belongs to the field of tobacco production, and in particular relates to a tobacco drying equipment. Background Technology

[0002] Tobacco curing is a crucial step in tobacco processing, directly impacting the quality of the leaves and the flavor of the final product. The main purpose of curing is to induce a series of physiological and biochemical changes within the tobacco leaves by controlling temperature, humidity, and time, removing excess moisture while preserving or developing ideal aroma components and color. Modern curing systems often employ intelligent control systems that monitor temperature and humidity changes in the curing barn in real time, ensuring precise execution of process parameters. Different varieties and parts of the tobacco leaf require adjusted curing profiles; for example, thicker upper leaves require a longer yellowing period, while thinner lower leaves require a shorter curing time. Successful curing results in leaves with a uniform orange-yellow or lemon-yellow color, a soft texture, and a rich aroma, laying the foundation for subsequent re-curing, fermentation, and cigarette making.

[0003] Comparing with Chinese Patent CN219438198U, a tobacco curing device is disclosed, including a curing box and hanging rods. Several hanging rods have circular mounting grooves at both ends, and fixed rods are fitted within these grooves. The fixed rods are fixed to one side of a rotating disk, which rotates to one side inside the curing box. A sliding plate slides on the fixed rods, with one side of the sliding plate fixedly connected to one end of a spring, and the other end of the spring fixedly connected to one side of the rotating disk. The lower end of the curing box has a curing mechanism for curing tobacco leaves placed on the hanging rods. The curing box also includes a monitoring component for easy observation of the tobacco curing process. The curing mechanism cures the tobacco leaves and removes moisture from the air inside the curing box. The drive component rotates the hanging rods via the rotating disk, ensuring even heating of the tobacco leaves. The monitoring component allows workers to easily observe the tobacco curing process.

[0004] However, the aforementioned patented horizontal setup occupies a large space and cannot make full use of the high-altitude space, resulting in space waste and low utilization rate. Therefore, a new device needs to be designed. Utility Model Content

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. By vertically supporting the tobacco and circulating it up and down for baking, the horizontal space occupied is reduced and the utilization rate of high space is improved; the electric motor drives the transmission chain to move the support rod up and down in a circulatory manner, so that the tobacco moves continuously during the baking process, avoiding the problems of local overheating or uneven drying caused by static baking.
