Technical Field
[0001] The utility model relates to the technical field of flue-cured tobacco baking control equipment, in particular to a device for rehumidifying tobacco leaves after baking. Background Art
[0002] The moisture recovery of tobacco leaves after curing is an important part of the tobacco curing process. Its efficiency and effect have a great impact on the quality, yield and utilization rate of tobacco leaves after curing, especially when the climate is dry and the number of curing rooms is insufficient. The moisture content of tobacco leaves after curing is generally 5% to 7%, which is very easy to break, and it is not convenient for the subsequent operations such as uncuring, unpiling, stacking and grading. Therefore, the tobacco leaves must be treated with moisture recovery after curing to make the moisture content of the tobacco leaves reach 12% to 14%, and the tobacco leaves are slightly softened before uncuring, unpiling, stacking and other operations are carried out to ensure that the quality and yield of the tobacco leaves are not lost.
[0003] In the treatment of tobacco leaf rehumidification, three rehumidification methods are generally used, namely natural rehumidification, humidification rehumidification and humidifier rehumidification. Natural rehumidification is to open all the doors and windows of the intensive curing room, and the tobacco leaves absorb moisture from the outside air to increase the water content. This method is subject to weather conditions and it is not easy to control the appropriate rehumidification degree. If there is a lot of rain, it is easy to rehumidify excessively, and if the weather is dry, the rehumidification time is long. Humidification rehumidification is to sprinkle water on the floor of the heating room of the intensive curing room, turn on the circulating fan, and increase the relative humidity in the curing room by evaporating the moisture on the ground, so that the tobacco leaves rehumidify. The rehumidification degree of this method is difficult to control, and it is easy to rehumidify excessively or insufficiently, and it requires manual regular watering, which increases labor.
[0004] The rehumidification of the humidifier may cause the tobacco leaves on the side of the humidifier to rehydrate faster, but the tobacco leaves on the back side to rehydrate slower, so the rehydration time of the tobacco leaves on the back side will increase, thereby lengthening the overall rehydration time, which in turn leads to higher overall energy consumption. Therefore, a post-cured tobacco leaf rehydration device is proposed to solve the above problem. Utility Model Content

[0033] Reference Figure 2-Figure 3 The outer wall of the rotating gear 302 is meshed with the outer wall of the transmission gear 303, and the meshing of the two can drive the transmission gear 303 to rotate.

[0035] Working principle: When relevant personnel need to rehumidify tobacco leaves, they will install the tobacco leaves on the bracket 307 and start the humidifier 2.

Due to the setting of the gear ring 305, the transmission gear 303 will rotate, thereby driving the rotating rod 306 to rotate. At this time, the rotating rod 306 rotates itself and also rotates around the center of the rotating gear 302, so that the exposed spray surface corresponding to the humidifier 2 is constantly changing, thereby avoiding the situation where the humidity at the front end of the tobacco leaves is higher and the humidity at the rear end is lower.
[0036] When the tobacco leaves rotate, when the amount of water inside reaches a certain level, the water will fall due to its own weight, and then enter the inner wall of the collection tank 309, and be discharged through the water outlet 310 to complete the collection.
