When a specific component is described as being connected to other components, the specific component may be directly connected to the other components without an intermediate component, or may not be directly connected to the other components but have an intermediate component.

[0024] All terms (including technical terms or scientific terms) used in the present disclosure have the same meanings as those understood by ordinary technicians in the field to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0025] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0026] In recent years, the research on the influence of key process parameters in the cigarette making process on the filling value of cut tobacco has mainly focused on the influence of process parameters such as cut tobacco moisture content, HT heating and humidification steam pressure and moisture content, drying cylinder wall temperature, hot air temperature, dehumidification damper opening and hot air flow direction during leaf drying process on the filling value of cut tobacco.

[0027] The moisture content of cut leaf is an important indicator of the precision processing level of leaf segments in the shredding process, but there are many factors that affect the fluctuation of this indicator. Therefore, the operability of using this indicator to control the filling value of tobacco is not strong. HT is a traditional method used by the tobacco industry to increase the temperature and control the humidity of tobacco materials. However, since this equipment is prone to cause material adhesion and there is steam overflow during the operation of the equipment, the stability of the equipment operation is affected, that is, the homogenization processing level is insufficient, and the equipment foundation for anchoring this equipment to control the filling value of tobacco is lacking. The tobacco drying machine is the main equipment that affects the filling value of tobacco, but the vast majority of current processes are through a single and simple regulation of a certain parameter of the tobacco drying machine, lacking a systematic and scientific combination of parameters, and it is difficult to achieve improvement in the filling value of tobacco by controlling a single parameter variable.

[0028] like Figure 1 As shown, the tobacco shred processing method for improving the filling value of shredded tobacco provided in this embodiment comprises the following steps in actual implementation:

[0029] Step S1, slicing process: the slicing width is 0.93mm-0.97mm.

[0030] The process flow rate of the slitting process is 2900 kg / h-3100 kg / h, for example, 3000 kg / h.

[0031] Specifically, in the shredding process, the shredding width is 0.95 mm. At present, the shredding width of conventional cigarettes produced by cigarette companies is generally set to 0.90 mm. In order to increase the filling value of tobacco shreds and reduce raw material consumption, the present invention can increase the shredding width to 0.93 mm-0.97 mm, for example, 0.95 mm, when producing conventional cigarettes, so as to increase the filling value of tobacco shreds by increasing the shredding width. After increasing the shredding width, the uniformity of tobacco shreds is better, the stability of the following two processes is improved, and each tobacco shred is ensured to be processed, thereby improving the filling value of tobacco shreds.

[0032] Furthermore, the moisture content of the cut tobacco is 19.5%-20.5%, and the moisture deviation of the cut tobacco is 0.5%-0.8%. By adjusting the moisture content of the cut tobacco and the moisture deviation of the cut tobacco, it is beneficial to control the moisture uniformity of the tobacco material, further improve the stability of the following two processes, and avoid uneven processes affecting the filling value of the tobacco.

[0033] Step S2, leaf shreds heating and humidification process: the outlet moisture content is 23%-25%, and the outlet temperature is 78°C-82°C.

[0034] The shredded leaf heating and humidification process is realized by Sirox heating and humidification equipment. Specifically, in the shredded leaf heating and humidification process, the outlet moisture content is 24%, the outlet temperature is 80°C, and the outlet moisture standard deviation is 0.4%-0.6%. The process flow rate of the shredded leaf heating and humidification process is consistent with that of the shredded process, which is 2900kg / h-3100 kg / h, for example, 3000 kg / h.

[0035] Under the conditions of shred width of 0.95 mm and material flow rate of 3000 kg / h, appropriately increasing the outlet moisture content and outlet temperature of the shredded tobacco heating and humidification process is beneficial to the improvement of the filling value of shredded tobacco.

[0036] Step S3, wire drying process: the drum wall temperature is 170°C-175°C, and the hot air temperature is 108°C-112°C.

[0037] The wire drying process is realized by a wire drying machine. The process flow rates of the wire cutting process, the wire heating and humidifying process and the wire drying process are consistent, which is 2900 kg / h-3100 kg / h. In one embodiment of the present invention, the process flow rates of the wire cutting process, the wire heating and humidifying process and the wire drying process are 3000 kg / h.

[0038] Specifically, in the drying process, the cylinder wall temperature is 173°C, the hot air temperature is 110°C, and the outlet moisture standard deviation is less than 0.3%. Under the condition that the incoming moisture, temperature and process flow rate are stable and unchanged, after changing the cylinder wall temperature, it is necessary to adjust the hot air temperature of the drying machine to meet the moisture content requirements of the tobacco after drying. Since the outlet moisture content and temperature of the leaf shreds are different in the heating and humidification process, that is, the moisture content and temperature of the tobacco are different when entering the drying machine, under the condition that the process flow rate is stable and unchanged, the drying machine will automatically adjust the cylinder wall temperature and hot air temperature according to the incoming moisture to achieve the moisture content of the tobacco after drying in accordance with the process standard requirements. The present invention can increase the temperature difference between the drying process and the on-site air selection process at the rear end by increasing the cylinder wall temperature in the drying process and correspondingly reducing the hot air temperature of the drying machine, so as to facilitate rapid cooling after entering the on-site air selection process, increase the brittleness of the tobacco, and make the tobacco harder, more elastic, and more substantial, so as to improve the filling value of the tobacco.

[0039] Increasing the shredding width in the shredding process will have a certain negative impact on the volatile aroma substance content and sensory quality of the tobacco after drying. Therefore, after increasing the shredded tobacco filling value by increasing the shredded width, other subsequent process parameters need to be coordinated, such as adjusting the shredded moisture content, the outlet moisture content and temperature of the leaf heating and humidification process, and the barrel wall temperature of the drying process, so as to avoid a major impact on the sensory quality of cigarettes.

[0040] Preferably, under the conditions of a shredded tobacco width of 0.95 mm, an outlet moisture content of 24% and an outlet temperature of 80°C in the shredded tobacco heating and humidification process, and a process flow rate of 3000 kg / h, the filling value of the shredded tobacco will be significantly improved when the barrel wall temperature is 173°C and the hot air temperature is 110°C.

[0041] In one embodiment of the present invention, a formula leaf group of another brand of cigarettes of a certain company is selected for application effect verification test, and the main process parameters of the test group (after optimization) and the control group (before optimization, i.e., large-scale production) are compared as shown in Table 1. Except for the different process parameter settings listed in Table 1, the other process parameters and process flow are the same.

[0042] Table 1 Comparison of process parameters before and after optimization

[0043]

[0044] The difference analysis results of tobacco filling value and sensory quality score before and after process parameter optimization are shown in Table 2. From the comparative analysis results, it can be seen that after the process parameters are optimized, the tobacco filling value is significantly improved (P < 0.05), and the sensory quality score is slightly reduced, but the reduction is not obvious (P > 0.05). The application effect shows that appropriately increasing the cut width, the moisture content and temperature of the tobacco heating and humidification outlet, and the wall temperature of the drying tube, and correspondingly reducing the hot air temperature of the drying machine, can effectively improve the tobacco filling value and reduce the production cost of cigarettes, and at the same time will not have a significant impact on the sensory quality of cigarettes.

[0046]

[0047] The method for improving the filling value of shredded tobacco provided by the embodiment of the present invention, under the framework of the unchanged overall process of shredded tobacco processing, improves the key process parameters such as the shredded width, the outlet moisture content and temperature of the shredded tobacco heating and humidification process, and the barrel wall temperature and hot air temperature of the shredded tobacco drying process in the shredded tobacco cutting section and the shredded tobacco drying section, thereby improving the shredded tobacco filling value and reducing the shredded tobacco crushing and consumption in the entire processing process; and provides a scientific process processing method for cigarette manufacturers to reduce raw material consumption while achieving stable cigarette product quality.
