Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to processing of tobacco raw materials, and more particularly to a method for blending tobacco cuts for improving the bulkiness, which is one of the characteristics of tobacco cuts.

[0002]

2. Description of the Related Art The shreds filled in a cigarette are manufactured from a tobacco raw material in which a plurality of types of tobacco raw materials are mixed.
The shreds are roughly classified into so-called deboning, which is obtained from lamina corresponding to the mesophyll part of leaf tobacco, and medium-bone shreds, which are obtained by harmonizing, pressing and cutting the petiole part of leaf tobacco.

The deboning is generally carried out by mixing and laminating a plurality of types of lamina, mixing them, and then mixing them, and then the deboned carving is carved with a carving width of about 0.8 mm and about 0.2 mm. Target.
Then, these are mixed in an appropriate ratio to obtain a cigarette filling cigarette.

Further, as disclosed in Japanese Patent Application Laid-Open No. 7-184624, harmonization, aroma and the like are applied to each kind of tobacco raw material, and the tobacco raw material is cut into different widths to obtain a product. There is a method of blending the carrots to prepare carton for cigarette filling.

[0005]

[Problems to be Solved by the Invention] The quality of cut tobacco depends on the taste quality of cigarette, moisture, product temperature, grain size,
It can be classified into physical properties such as bulkiness. Among these, the bulkiness, while maintaining the hardness of the cigarette when cigarettes are filled with cigarettes, will be able to reduce the amount of cigarettes to be filled, reducing the cigarette manufacturing cost by reducing the amount of raw materials used. It is possible to plan.

Here, the swelling property represents the volume (cc) of the shreds when 1 g of shreds is compressed with a constant pressure.
Is measured by a so-called bulge-bulk measuring device 10 manufactured by Borgwald.

The method of measuring the swelling property will be briefly described. First, a sample of 20 ± 0.01 g is usually weighed and placed in the cylindrical container 11. Then, the sample is loaded into the measuring machine using a loading assisting device (not shown). Next, the sample in the measuring machine is pressurized with a constant load (for example, 3 kg) for a constant time (for example, 30 seconds). This pressurization is automatically made by pushing down the piston 12 with a measuring machine,
The final height, that is, the compressed height h in the figure is automatically recorded.

Since the bulkiness varies depending on the water content of the raw material,
Next, the water content is measured. The difference in moisture release weight before and after drying at 100 ° C. is defined as water content. Therefore, the water content is calculated by the following formula. Water content [%] = (weight before drying−weight after drying) / weight before drying × 100

Then, the swelling property at a standard water content of 12% is calculated, and this value is used as a measurement value of the swelling property. Therefore, the bulkiness is calculated by the following formula. Here, the moisture correction coefficient is 0.364.

In the method described in the above-mentioned JP-A-7-184624, in order to increase the filling force of tobacco shreds, that is, the bulkiness, the cutting width is changed for each kind of tobacco material, and the cutting is different. Tobacco shreds are made by blending tobacco shreds obtained from different tobacco raw materials with different cutting widths. With this technology, let's cut different tobacco raw materials by flowing different tobacco raw materials in one line in time series. And if
Since the processing time for humidity control and aroma of the tobacco raw material before cutting becomes long, a storage device for each tobacco raw material is required.

Further, when the technology is to be processed by a plurality of lines, a plurality of processing lines are required according to the kind of the tobacco raw material, and in any method, it leads to the expansion of the raw material processing equipment, This leads to an increase in initial cost and running cost.

[0012] The present invention has been made in view of the above problems, and obtains the chopped tobacco raw material with different cutting widths without increasing the equipment for the raw material processing step, thereby improving the taste quality and the like. It is an object of the present invention to improve the swelling property of the shreds for blending the shreds and to reduce the cost by reducing the amount of raw materials used without affecting the above.

[0013]

According to the first aspect of the present invention,
A method of blending tobacco shreds, wherein a plurality of types of tobacco are blended with each other to cut tobacco raw materials with different carving widths to form a plurality of types of tobacco carving with different carving widths, and mixing the tobacco carving,
Characterized by carving for cigarette filling.

In a sixth aspect of the present invention, a plurality of cutting means having different cutting widths for each table are used to cut a tobacco raw material in which a plurality of types of tobacco are blended. It is characterized in that tobacco shreds are produced and the tobacco shreds are mixed in the steps after the cutting means.

According to a seventh aspect of the present invention, a tobacco material having a plurality of types of tobacco blended therein is cut with different cutting widths by a single cutting means to produce tobacco cuts having different cutting widths. However, the tobacco shreds are mixed in the steps after the cutting means.

Further, according to the present invention, it is possible to obtain a chop having a different cutting width of the tobacco raw material without increasing the equipment for the raw material processing step. The bulkiness can be increased.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION First, an engraving property confirmation test conducted to complete the present invention will be described. This test was carried out to confirm the effect of improving the engraving property by giving a distribution to this engraving width, while the conventional engraving width was kept constant at 0.8 mm.

The factors and levels in this test are shown in Table 1.
The factors are: uniform products with single carvings, balanced products with a plurality of carvings at the same ratio, weight products with a higher mixing ratio for a specific carving, and two types of carvings. There are four divided products with mixed width markings. The level for each factor is 0.6 mm for uniform width products
There were four levels of 0.8 mm, 1.0 mm and 1.2 mm. Also, for balanced products of carving width, 0.6 mm,
It was set as one level of a uniformly distributed product with 0.8 mm, 1.0 mm and 1.2 mm intervals. Further, as the weight product of the carving width, four levels were prepared in which the carving weights of the above-mentioned four kinds of carving widths were weighted for specific carving widths. In addition, for the divided products of carved width,
Two types of pitches were selected from the above four types of pitches to obtain 8 levels.

[0023]

[Table 1]

Table 2 is a lot classification table. Step size is 0.
There are 4 types of 6 mm, 0.8 mm, 1.0 mm and 1.2 mm, 4 lots for uniform products, 1 lot for balanced products, and 50% for weight products with the largest mixing ratio for one type of engraving width. And below 20
There are two kinds of the mixture width of% and the minimum mixture ratio is 1
4 lots were prepared as 0%. Furthermore, for the divided products, the mixing ratio was set to 50% for each of the two types of carving width, but for the combination of 0.8 mm and 1.2 mm,
Two lots were prepared, one of which was 70% and the other was 30%, and eight lots of divided products were prepared. Above, 1 in total
Seven lots were tested.

[0025]

[Table 2]

After the materials of each of the above lots were naturally harmonized, the bulkiness was measured by the Borgwald method. A concrete test procedure was as follows: 100 kg of a raw material was collected from a transportation vehicle, and this raw material was divided into 4 parts and divided into 4 lots of 10 kg material samples. And, these raw material samples, respectively, carving width 0.6mm, 0.8mm,
It was cut into 1.0 mm and 1.2 mm, and the cut raw materials were mixed to prepare each lot shown in the above lot classification table. Then, the bulkiness of each lot was measured. still,
Ten samples for moisture measurement were sampled from each lot and the moisture was measured to correct the bulkiness of the moisture.

FIG. 8 shows the test results for all lots, which will be discussed below. FIG. 3 shows the relationship between the cut width and the bulkiness when the tobacco cuts having different cut widths are individually measured. As is clear from this figure, the bulkiness of the uniform product tends to increase as the carving width increases. Therefore, judging from this result, when it is intended to manufacture high-bulk carvings, to reduce cigarette filling carving, and to reduce costs, simply use high-bulky carvings. It would be better to use a pitch of 0.2 mm. However, if you fill the cigarette with 1.2 mm increments alone,
Since the average particle size of the shreds is large, gaps are created in the distribution of the shreds filled in the cigarette during winding up as a cigarette, the combustibility of the cigarette improves, the combustion speed becomes faster, and the combustibility changes. However, it was found by the tests conducted at the same time as the above tests that the taste quality fluctuates, which is not preferable. Therefore, simply
The object of the present invention cannot be achieved only by setting mm.

Therefore, the inventor of the present invention has a range of pitches in which the generation of dust is small before being wound up on a cigarette, and there are few gaps in the distribution of the cuts in the state of being filled in the cigarettes. Focused on the different blending method of tobacco.

Next, as for the balanced product (lot No. 5), as shown in FIG.
4) was not weight averaged, and was larger than Lot No. 3 having a carving width of 1 mm. The bulkiness of this balanced product is larger than that of various weight products (lot Nos. 6 to 9) as shown in FIG. 4, and blending ticks having different cutting widths is a measure for improving the bulkiness. Considered to be effective.

Next, the test results of the divided products are shown in FIG. As is clear from this figure, two different kinds of engraved products
In the case of mixing by%, the case of mixing those having similar pitches (Lot Nos. 14, 13, 1) is more than the case of mixing those having different pitches (Lot Nos. 11, 12).
It can be seen that the bulkiness is larger in 5). However, in order to obtain cuts with high bulkiness by mixing different cuts of different tobacco widths, in order to obtain cuts with a high bulkiness, it is necessary to use two kinds of cuts with different cut widths and different average particle size distribution of the tobacco cuts.
The bulkiness as a simple average value of the bulkiness of a single pitch is not obtained, that is, the bulkiness value with additivity is not marked, and at least three types of pitch are It was found that by blending the tobacco shreds, shreds having a high bulkiness, which is higher than the additivity, can be obtained in which each pitch is higher than the weighted average bulkiness of the individual shreds.

Further, as shown in FIG. 6 and FIG. 7, in the conventionally used lot No. 2 uniform product of 0.8 mm carving width,
Lots with different widths added (No 12, 13, 1)
Nos. 4, 16 and 17) had a bulk density smaller than that of the uniform product having a carving width of 0.8 mm, and no improvement in bulkiness was observed.

From the above results, it is understood that three or more kinds, preferably four or more kinds of tobacco cuts having different cutting widths may be blended in order to obtain cuts having high bulkiness.

Next, an example of an apparatus for concretely implementing the above-mentioned method of blending tobacco shreds will be described. FIG.
3 is a flowchart showing an embodiment of this device. First, a plurality of cigarettes are blended by the blending means 2. After that, the blended tobacco raw material is cut by the cutting means 3 (3A to 3D). In the present embodiment, the respective cutting means 3A to 3D are arranged in parallel, and the cutting width at the time of cutting is different by these cutting means, and the cutting means 3A cuts the cutting width of 0.6 mm. Carving means 3B, 3
In C and 3D, 0.8 mm, 1.0 mm, 1.
2 mm carvings are obtained.

The chopped raw materials are mixed in a step during storage in a silo or the like and dried by a drying means 4 and then stored in a final storage means 5 as cuts for cigarette filling, and wound up on a cigarette in the next step. To be

Further, in the above-mentioned embodiment, the means for performing the engraving with different engraving widths by a plurality of engraving machines is shown, but each engraving machine changes the engraving width according to the flow time of the raw material. With this setting, it is also possible to carve different carving widths with the same carving machine.
