Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette production equipment, and particularly relates to a multi-point injection tobacco moisture regeneration device based on outlet moisture prediction. Background Art

[0002] In the production process of cigarettes, the baked tobacco leaves need to be cut into shreds. In order to improve the processing resistance of the tobacco leaves and meet other process requirements, there are certain requirements for the moisture content of the tobacco in the shredding process. In order to make the moisture content of the tobacco meet the process requirements, it is necessary to add an appropriate amount of moisture to it through a tobacco rehumidification device.

[0003] At present, the commonly used method of adding moisture to the tobacco rehumidification device is to spray water mist into the rehumidification cylinder through a single nozzle at one end of the cylinder, and adjust the water volume and water pressure of the injector according to the feedback of the moisture content of the outlet tobacco. However, when there is a lot of tobacco in the rehumidification cylinder, the single-point injection method may cause the tobacco to absorb water unevenly. In addition, after adjusting the water volume and water pressure of the injector, it takes several minutes to detect the change of the outlet moisture. If the outlet moisture does not meet the requirements, it needs to be adjusted again. This will cause the moisture content of the tobacco to fluctuate greatly during the waiting period, and even exceed the required range of the process parameters, resulting in substandard tobacco production. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-point injection tobacco rehumidification device based on outlet moisture prediction, so as to overcome the technical problems in the prior art that the tobacco rehumidification device can only spray water into the rehumidification cylinder in a single-point injection manner, resulting in uneven water absorption of tobacco, and the slow change in the outlet tobacco moisture content detection leads to large fluctuations in the tobacco moisture content, even exceeding the range of process parameter requirements, resulting in substandard tobacco production.
