[0026] In the description of this embodiment, the terms "up", "down", "left", "right", and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on this application.

[0027] like Figure 1-7Embodiment 1 is a cigar tobacco leaf moistening and conditioning production line, comprising: a feeding system 1, a moistening system 2, an air cooling system 3 and a collecting system 4 arranged in sequence according to the flow direction of tobacco leaves; the feeding system 1 feeds the moistening system 2 quantitatively; Figure 2 The moistening system 2 includes: a weighing unit 21, a first moisture detection unit 22, a loosening unit 23, and a moistening unit 24 arranged in sequence according to the flow direction of the tobacco leaves; the tobacco leaves transported by the feeding system 1 fall into the weighing unit 21, and the weighing unit 21 measures and feedbacks the feeding of the feeding system 1; the tobacco leaves enter the moistening unit 24 after being detected by the first moisture detection unit 22 and loosened by the loosening unit 23, and the moisture detection result of the first moisture detection unit 22 is fed back to control the moistening unit 24, wherein the loosening unit 23 is specifically a loosening vibration trough; the moistening unit 24 includes a moistening roller 241, such as Figure 3 A steam nozzle 242 is installed at the entrance of the moistening roller 241. The angle and spray diameter of the steam nozzle 242 are adjustable. A hot air outlet 243 is arranged at the entrance of the moistening roller 241. The hot air temperature and air volume are adjustable. A return air outlet 244 is arranged at the outlet. The hot air and tobacco leaves flow in the moistening roller 241 in the same direction. The rotation speed of the moistening roller 241 is adjustable. The moistening roller 241 brings the tobacco leaves to a high place and drops them down. The tobacco leaves are exposed to steam and hot air during the falling process. The air cooling system 3 cools down the tobacco leaves moistened by the moistening system 2. The collecting system 4 evenly loads the tobacco leaves into the collecting container.

[0028] A steam nozzle 242 is installed at the entrance of the dampening roller 241. The angle and spray diameter of the steam nozzle 242 are adjustable to meet various moisture requirements. There is a hot air outlet 243 for hot air outlet at the entrance of the dampening roller 241. The temperature and air volume of the hot air are adjustable. There is a return air outlet 244 for returning hot air and steam at the outlet. The hot air flow direction is consistent with the flow direction of the tobacco material. The hot air provides heat for the tobacco leaves, and the hot air and steam are recovered through the return air outlet 244. The rotation rate of the cylinder of the dampening roller 241 is adjustable. The tobacco leaves are fully in contact with the steam sprayed from the steam nozzle 242 and the hot air sprayed from the hot air outlet 243 during the falling process. The process of turning the tobacco leaves is continuous and the turning effect is good, and no manual hanging rod is required. The synergistic effect of hot air and steam can enable tobacco leaves to quickly absorb moisture in a high temperature and high humidity environment. Specifically, it also includes a feed port 246 and a discharge port 247.

[0029] Preferably, if Figure 4 The inner wall of the dampening drum 241 is provided with a lifting plate 245, which brings the tobacco leaves to a high place and throws them down. The tobacco leaves are loosened and contacted with steam and hot air during the falling process. The tobacco leaves can quickly absorb moisture in this process. This process is repeated many times, and the moisture uniformity of the tobacco leaves is high. Compared with a smooth inner wall or a rake tooth set on the inner wall, the lifting plate 245 has good flexibility and can reduce the damage of tobacco leaves.

[0030] The humidification unit 24 includes a humidification tank body, which includes a pure water tank. In other embodiments, it may optionally include one or more material tanks and special tanks. In addition to humidification, the tobacco leaves may also be added with materials, enzymes, mold, additives, etc. as needed, which is beneficial to enrich the uses of tobacco leaves and improve the quality of tobacco leaves.

[0031] In this embodiment, the humidification system 2 includes a second moisture detection unit 25 arranged behind the humidification unit 24 according to the flow direction of the tobacco leaves. The second moisture detection unit 25 is electrically connected to the feeding system 1 and the humidification system 2. The moisture detection result is fed back to adjust the tobacco leaf feeding flow and the water addition flow. The moisture detection of the tobacco leaves after humidification can timely reflect the humidification effect. The humidification conditions are adjusted according to the humidification effect in a timely manner to further improve the effect and efficiency of humidification. For example, the humidification water flow can be controlled by the algorithm and linkage mechanism between the material flow, inlet moisture, outlet moisture, humidification water flow, and required moisture, so that the relationship between tobacco leaf moisture and water addition amount is changed from human experience control to data and algorithm linkage control, thereby improving the accuracy and precision of tobacco leaf humidification.

[0032] like Figure 5 In this embodiment, the feeding system 1 includes a box turning unit 11, a feeding bin 12 and a lifting belt 13. The box turning unit 11 can turn the boxed tobacco leaves into the feeding bin 12. A feeding belt is provided at the bottom of the feeding bin 12. The feeding belt conveys the tobacco leaves to the lifting belt 13. After being lifted, the tobacco leaves fall into the humidification system 2 through the drop hopper. The feeding system 1 is a flexible feeding system, and the box turning and belt conveying operations cause less damage to the tobacco leaves.

[0033] In the present embodiment, the lifting belt 13 is a scraper type lifting belt. Similar to the scraper plate 245, the scraper type lifting belt can reduce the damage of cigar tobacco leaves more than the commonly used rake tooth type lifting belt in the prior art.

[0034] The weighing unit 21 receives tobacco leaves delivered by the feeding system 1, and controls the operation of the feeding system 1 by measuring weight feedback. The tobacco leaves are quickly tested for moisture by the first moisture detection unit 22 and further loosened by the loosening unit 23 before entering the moistening drum 241. The feeding step does not require manual labor and has a high degree of automation.

[0035] The present application is provided with an air cooling system 3, which can automatically air cool the moistened tobacco leaves to maintain the consistency of the moisture content of the tobacco leaves. A collection system 4 is also provided for automatic collection to reduce manual labor.

[0036] In this embodiment, the tobacco leaves discharged from the discharge port 247 are loosened and conveyed to the air cooling system 3 through the conveying vibration trough 26. The tobacco leaves are cooled to a temperature less than or equal to 25° C. by the air cooling system 3. The cigar tobacco leaves that are quickly cooled to a temperature range can be directly packaged, reducing the cooling process and avoiding the risks of rotting, carbonization, etc., without the need for additional moisture balance.

[0037] In this embodiment, the air cooling system 3 includes an air cooling vibration trough 31, which is in the shape of a mesh belt, with a blower 32 installed at the lower side and an exhaust port 33 installed at the upper side. When the tobacco leaves pass through the air cooling vibration trough 31, they are exposed to cold air. The air cooling vibration trough 31 can quickly reduce the temperature of the tobacco leaves and fully loosen the tobacco leaves to avoid adhesion. In addition, the mesh belt-shaped air cooling vibration trough 31 has good flexibility and is not easy to damage the tobacco leaves. It can also play a conveying role and send the tobacco leaves to subsequent workstations.

[0038] In this embodiment, the collection system 4 includes a bidirectionally movable cloth belt 41, and the cooled loose tobacco leaves fall onto the cloth belt 41. There is a receiving port 42 below the cloth belt 41, and the tobacco leaves fall into the collection container layer by layer evenly through the receiving port 42. Specifically, the cloth belt is a horizontal bidirectional cloth belt with two receiving ports at the bottom, which can evenly load the tobacco leaves into, for example, a stainless steel tobacco box or a transfer box for subsequent fermentation, stem removal and other treatments.

[0039] The cigar tobacco moistening and moistening production line of the present application can realize full-process mechanization and automation. By setting up a feeding system 1, a moistening system 2, an air cooling system 3 and a collection system 4, the production line can realize continuous mechanized production, improve the efficiency and effect of moistening cigar tobacco, and ensure product quality.

[0040] The cigar tobacco leaf moistening production line and method of the present invention draw on the advantages of high temperature and high humidity in a small environment of steam moistening to promote absorption, and design a feeding unit, a moistening unit, a steam injection unit, a hot air circulation unit, an air cooling unit, a collecting unit and other devices to solve the time-consuming problems of hanging and collecting, realize continuous production, and improve the cigar tobacco leaf moistening efficiency and moistening effect.

[0041] Embodiment 2 is a method for moisturizing cigar tobacco leaves, comprising the following steps: turning the tobacco leaves in a drum and making the tobacco leaves contact with steam and hot air in the same direction as the tobacco leaves at the same time, and then cooling the tobacco leaves to less than or equal to 25° C. The method for moisturizing cigar tobacco leaves has the beneficial effects of high moisturizing efficiency, no need for moisture balance, less manual participation, and easy and precise control of key parameters in the moisturizing process.

[0042] Specifically, the production line of Example 1 is used to moisturize cigar tobacco leaves.

[0043] The tobacco leaves are turned over in the drum and are simultaneously contacted with steam and hot air in the same direction as the tobacco leaves by the humidification unit 24 , and the tobacco leaves are cooled to a temperature of less than or equal to 25° C. by the air-cooled vibration trough 31 .
