Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing, and more particularly to a method for improving the filling value of medium-sized cigarettes without increasing consumption. Background Art

[0002] Medium-length cigarettes, as a new type of cigarette with a circumference of 20mm, are becoming increasingly popular among cigarette consumers. Compared with conventional cigarettes, medium-length cigarettes have the characteristics of small circumference and long length (conventional cigarettes are generally 84mm long, and medium-length cigarettes are generally 90mm or 88mm long). Due to the difference in external dimensions, the tobacco consumption per medium-length cigarette (the amount of tobacco in a cigarette) is reduced, the amount of tobacco required to fill the cigarette tube is reduced, and the compression between tobacco is reduced, which can easily cause the end of the cigarette to be empty or the end of the cigarette to fall, thus producing quality defective samples.

[0003] The filling value of tobacco shreds is a quality indicator that is widely concerned in the tobacco industry. The "Cigarette Process Specifications" stipulate that the filling value of tobacco shreds after the drying process should be ≥4.0cm 3 / g, in order to improve the quality of cigarette rolling of medium-length cigarettes, the tobacco industry generally agrees that by increasing the filling value of tobacco shreds in medium-length cigarettes, the supporting force between tobacco shreds can be increased, which will ultimately reduce the occurrence of quality defects such as loose ends in medium-length cigarettes.

[0004] Therefore, there is an urgent need for a method for increasing the filling value of medium cigarettes without increasing consumption. Summary of the invention

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.

[0022] 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.

[0023] 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.

[0024] At present, tobacco companies in the tobacco industry generally improve the filling value of tobacco shreds through key processes in the silk-making process, such as drying process, on-site air selection process or cooling process. In the drying process, the airflow wire drying process is generally used, and the thin plate wire drying process is abandoned. In the airflow wire drying process, a higher wire drying temperature (220-280℃) is used to quickly dehydrate the tobacco shreds in a short time, thereby making the tobacco shreds crispy on the outside and tender on the inside, instantly improving the filling value of the tobacco shreds; in the on-site air selection or cooling process, the above two processes are after the wire drying process. The main process task is to remove the stems in the tobacco shreds, but because these two processes have the effect of cooling, the surface temperature of the tobacco shreds will decrease when passing through, which will also increase the brittleness of the tobacco surface, thereby improving the filling value of the tobacco shreds.

[0025] From the perspective of basic processing principles, the drying process can indeed increase the filling value of tobacco. However, due to the accelerated dehydration of tobacco, the free water on the surface of the tobacco is instantly lost, but the bound water inside is still maintained. This process has two undesirable results. First, the tobacco is too brittle during the processing and a large amount of crushing occurs. Research data show that the yield of airflow-dried tobacco is only about 97%, while the yield of thin-plate dried tobacco (the drying temperature is much lower than that of airflow drying) is above 99%. The dry head and tail rate of airflow-dried tobacco is generally around 0.7% (that is, the proportion of material heads and tails in the drying process, which reflects consumption to a certain extent), which is much higher than that of thin-plate drying. Second, airflow-dried tobacco often has some burnt smell and a reduced sensory quality due to its high strength and fast dehydration.

[0026] In addition, although the on-site air selection or cooling process both have the effect of cooling the tobacco, since these two processes are both after the tobacco drying process, the temperature at the processing site itself is very high, and the wind used for cooling in the above two processes comes from the site. In layman's terms, it is cooling with hot air. Therefore, the whole method of using wind temperature to cool the tobacco and then increase the tobacco filling value is not ideal.

[0027] In summary, the methods currently available in the tobacco industry to increase the filling value of tobacco shreds all have drawbacks, and the results have not reached the ideal goal.

[0028] like Figure 1 As shown, the method for increasing the filling value of a medium cigarette without increasing consumption provided in this embodiment comprises the following steps in actual implementation:

[0029] Step S1, a tobacco shred drying process, using a thin plate tobacco shred drying drum to dry the tobacco shreds.

[0030] In the present invention, a thin plate roller is used for the tobacco drying process to slowly and gently dehydrate the tobacco shreds, wherein in the tobacco drying process, the process flow of the tobacco shreds is 5000 kg / h-6000 kg / h, for example, 5500 kg / h, the thin plate temperature is: 120℃-150℃, for example, 130℃, the circulating air temperature is 100℃-110℃, for example, 105℃, the tobacco shreds temperature at the tobacco drying process outlet is 50℃-65℃, for example, 55℃, and the dry head and tail rate is below 0.5%, for example, 0.3%.

[0031] Step S2: trimming the tobacco shreds after drying using a thinning roller to reduce the length of the tobacco shreds.

[0032] The present invention uses a shredding roller to trim the tobacco shreds, thereby reducing the length of the tobacco shreds. The shredding roller is arranged at the feeding position of the on-site air separation process. Specifically, the shredding roller includes a group of relatively arranged movable knives and fixed knives. The striking action of the movable knives and the fixed knives reduces the length of the tobacco shreds and achieves a trimming effect. The spacing between the movable knives and the fixed knives is 10cm-15cm, for example, 12cm. It should be noted that the present invention does not specifically limit the spacing between the knives and the fixed knives.

[0033] In some embodiments of the present invention, the length of the unraveling roller is consistent with the width of the feed vibration trough, which is 1.8m-2.2m, for example, 2m, the diameter of the unraveling roller is 40cm-60cm, for example, 50cm, the striking frequency of the unraveling roller is 90r / min-120r / min, for example, 105r / min, and the process flow rate of the unraveling roller matches the silk drying process, which is 5000kg / h-6000kg / h, for example, 5500 kg / h.

[0034] Step S3, on-site air selection process, using on-site air selection equipment and air conditioning units to perform on-site air selection to reduce the temperature of the tobacco.

[0035] The air conditioning unit includes two vertical air conditioners, which are arranged next to the on-site air selection device. In the present invention, the wind for on-site air selection adopts air-conditioned wind. By arranging two sets of vertical air conditioners next to the on-site air selection device, air-conditioned cold wind is introduced to achieve flow balancing, filtering and cooling, thereby improving the filling value of the passed tobacco.

[0036] Specifically, in the on-site air selection process, the air flow rate of the vertical air conditioner is 2.5kg / (m·s)-3.5kg / (m·s), and the air temperature is 16°C-18°C.

[0037] After using this new process, the filling value of medium-sized cigarettes can be increased from 3.8 cm before use. 3 / g, increased to 4.1 cm 3 / g; the tobacco yield increased from 97% to 99.4%, the dry head and dry tail rate decreased to 0.4%, and the average length of tobacco decreased from 4.28cm to 2.21cm. The statistical results of the influence of traditional and new processes on tobacco filling value and consumption are shown in Table 1.

[0039]

[0040] The method for improving the filling value of medium-length cigarettes without increasing consumption provided by an embodiment of the present invention comprises the following steps: adding a thinning roller to the on-site air selection feeding point, so as to reduce the length of tobacco shreds by using the thinning roller, thereby improving the filling value of tobacco shreds; introducing cold air from an air conditioner at the on-site air selection process, so that the filling value of tobacco shreds increases during the extremely rapid cooling process; while improving the filling value of tobacco shreds, tobacco shreds are not crushed, so as to avoid that the tobacco shreds are burnt on the outside and tender on the inside, thereby ensuring the stability of the sensory quality of the tobacco shreds and the stable improvement of the filling value of the tobacco shreds.
