Embodiment Construction
[0040] Combine below Figure 1 to Figure 5 The technical solution provided by the present invention is described in more detail.
[0041] Cigarettes include shredded tobacco and smoking materials. Cigarette materials include small box label paper, splicing paper, cigarette paper, etc. Cut tobacco is a porous medium composed of complex organic substances. In the tobacco processing process, the moisture content control of tobacco leaves (or cut tobacco) is an important content of processing quality control, and the process of moisture absorption, moisture absorption and drying and dehumidification of tobacco directly affects the quality of in-process products. In addition, smoking materials, such as small box label paper, splicing paper, cigarette paper, etc., have different moisture absorption and dehumidification performances under different temperature and humidity environments.

The invention discloses a method for controlling the moisture content of cigarettes, which relates to the field of tobacco manufacturing and is used for optimizing the quality of cigarettes. The method comprises the following steps: calculating the theoretical moisture content of shredded tobacco; calculating the theoretical relative humidity of shredded tobacco according to the isothermal adsorption-desorption characteristic curve of shredded tobacco and the theoretical moisture content of shredded tobacco; and calculating the theoretical relative humidity of shredded tobacco according to the theoretical relative humidity of shredded tobacco. Target relative humidity: calculating the target moisture content of the smoking material according to the target relative humidity of the smoking material. The above-mentioned technical solution effectively adjusts the moisture content of the shredded tobacco and the tobacco material. After the finished cigarette is produced in subsequent cigarette production, there will be basically no moisture migration between the shredded tobacco and the tobacco material, which greatly improves the quality of the finished cigarette.
Description
technical field [0001] The invention relates to the field of tobacco manufacturing, in particular to a method for controlling the moisture content of cigarettes. Background technique [0002] Cigarettes include shredded tobacco, cigarette paper, filter rods, label paper and other substances. During the storage of cigarettes, cigarettes are prone to macula and mildew caused by microbial growth. [0003] In related technologies, in order to reduce the probability of the aforementioned qualitative change in cigarettes, the following measures are taken: controlling the ambient temperature and humidity of the packing workshop so that the temperature and humidity of the storage environment meet the requirements. [0004] The inventors have found that at least the following problems exist in the prior art: in the prior art, the method of controlling the temperature and humidity of the storage environment takes a long time, such as several months, to adjust the humidity of the ciga...
