Wrinkled sheet tobacco manufacturing method

[Technical field ]

The present invention relates to a method for producing a tobacco sheet used for materials such as cigarettes. In more detail, the present invention relates to a sheet tobacco obtained by binding tobacco tobacco such as tobacco powder with a binder and having a large wrinkle. Refer to the manufacturing method.

[Background Tech]

For ordinary cigarettes such as rolled tobacco, so-called cut tobacco, which is made by cutting tobacco leaves, is used. In the process of cutting tobacco, or in other tobacco manufacturing processes, various tobacco tobacco such as leaf scraps, chopping, powdered tobacco, and bone are generated. . To make effective use of these tobaccos, combine the tobaccos from the country with an appropriate binder, add reinforcing materials, moisturizing agents, etc. Rolled out from between the rolls to form a sheet, separated from the sheet adhering to the surface of one of the rollers with a dowel knife to produce a sheet cigarette (Japanese Patent Application Publication No. 5919 of 1968). This sheet tobacco is cut and mixed with the cut tobacco and used as a raw material for cigarettes.

If a sheet tobacco manufactured in this way is wrinkled, the bulk of the sheet tobacco when cut is increased.

(I.e., it is bulky), so that the amount of shredded tobacco wound on the tobacco can be reduced, which is economically advantageous. . According to the method described above, wrinkles are attached to the sheet when the sheet is covered with doctor life. However, as shown in Fig. 1, the wrinkles of the sheet obtained in this way have a spacing of 0.1 to 0.2 when a sheet with a thickness of O.lBa is used. aa, the wrinkle height is only fine about 0.2ma in thickness of the sheet, and the increase in swelling when cut is not so large. Japanese Patent Publication No. S48-4919 mentioned above discloses that large wrinkles can be formed by using a special doctor tanif. . However, it has the disadvantage that the formation of large wrinkles becomes difficult within a short time due to the wear of the doctor knife.

[Disclosure of the Invention]

An object of the present invention is to provide a method for producing a bulky sheet tobacco which can form a large wrinkle even when the doctanaif is worn. It is to be .

This goal was achieved by using specific substances in specific amounts as binders. That is, in this invention, the raw material granules containing the tobacco are wetted with water, and the obtained wet granules are extruded from between a pair of rolling rolls. A sheet tobacco adhered and formed on one surface of the rolling roll is separated by using a knife and a cutter knife to produce a wrinkled sheet tobacco. In addition, the present invention provides a method comprising adding any one of the substances selected from the following group to the raw material powder in an amount shown below. The following The amount is based on the weight of the whole wet granules before adding water (that is, the total weight of the raw material granules).

(2) Hydrolysis starch with a molecular weight of 100,000 to 900,000, arabia gum, carbogishi methylcellulose salt with a molecular weight of 10,000 to 20,000 or a degree of methoxylation of 7 High-methoxy lectin having an esterification degree of 62 to 77% at ~ 17%: ~ 11% by weight,

(3) Mixture of 4,4,8-triglycol saccharide polymer and sodium salt of carboxymethylcellulose 1.3 to 7.3% by weight of the former 1.3-3.2% by weight of the latter

By adding one of these substances as a binder to the raw material granules in the above-mentioned amount in the above-mentioned amount, the interval is approximately 2 a and the height is approximately 1. A wrinkled sheet tobacco is obtained. The wrinkles imparted by the method of the present invention are different from those obtained by the conventional method. As shown in FIG. 2, small wrinkles are present in large wrinkles. Exists and becomes more bulky. Furthermore, the method of the present invention does not require a special doctor tanife as described in JP-B-48-5919, and the doctor knives are quite substantial. Even when worn, large wrinkles can be formed. In addition, the sheet tobacco obtained by the method of the present invention has excellent water resistance as shown in the examples described later, and has a good taste when smoking.

The (-) mark indicates that the molding condition is poor due to a sheet tear or a sword male defect.

As can be seen from the results shown in Table 1, when alpha-modified starch was used as a binder, it was shown in FIG. 2 when the blending amount was 4 to 10% by weight. The formation of wrinkles as shown is remarkable, and the swelling is increased by 5 to 23% compared to the conventional sheet tobacco, which is slightly different from starch raw material, and also has water resistance. Also increase by 80 to 210%. On the other hand, when dialdehyde starch, etherified starch, and phosphoric acid starch are used as binders, no wrinkles are formed and the swelling property is the same as that of a conventional sheet. Tobacco is less abundant and does not increase water resistance.

Also, as can be seen from the results shown in Table 2, when the hydrolyzed starch is used as a binder, the molecular weight of 100,000 to 900,000 can be reduced to 4 to 11% by weight. When blended in proportions, the formation of wrinkles as shown in Fig. 2 is remarkable, and the bulkiness is increased by 9 to 13% as compared with conventional sheet tobacco, and the water resistance is also 10%. Add ~ 3 3%. However, when a hydrolyzed starch having a higher molecular weight of 10,000 to 90,000 is used, the swelling and water resistance are lower than those of conventional sheet tobacco, and the molecular weight is lower. However, when a hydrolyzed starch having a low degree of decomposition of 1,000,000 to 900,000 is used, no wrinkles are formed and the swelling property is further inferior.
