Definitions

  • the present invention relates to a method of manufacturing wrinkled sheet tobacco by wetting a raw material, powder containing tobacco with water, extruding the resultant wet powder through a gap between a pair of rollers, and separating sheet tobacco attached to the surface of one roller with a doctor knife, wherein a binder is added to the raw material powder.
  • So-called cut tobacco obtained by cutting tobacco leaves is used for usual tobacco articles such as cigarettes.
  • various types of tobacco waste such as leaf waste, cut waste, powder tobacco, or rib waste are produced.
  • a suitable binder in order to effectively utilize such tobacco waste, it is bound with a suitable binder, and added with a reinforcing agent, a humectant, and the like.
  • the mixture is extruded through a gap between a pair of rollers to form a sheet, and the sheet attached to the surface of one roller is separated therefrom with a doctor knife to obtain sheet tobacco (see Japanese Patent Publication No. 48-5919).
  • the sheet tobacco is cut and mixed with normal cut tobacco and used as a raw material for cigarettes and the like.
  • US-A-3 430 634 discloses a process for making a tobacco product for using a smokable article.
  • the process involves formation of an aqueous slurry, wherein a wet mixture containing tobacco and a binder is extruded through a gap between a pair of rollers and sheet tobacco attached to the surface of one roller is separated with a doctor knife.
  • a binder is mentioned no specific examples are recited.
  • the said document does not even remotely suggest that the use of a binder is involved in the formation of wrinkles in a sheet tobacco.
  • US-A-2 887 414 discloses a method of making tobacco smoking material by using specific adhesives.
  • the use of any particular binder for the formation of wrinkles in a sheet tobacco is neither disclosed nor suggested.
  • BE-A-525 814 does not disclose or suggest that the use of a binder is involved in the formation of wrinkles in a sheet tobacco, although the use of pectin or a derivative thereof is being mentioned in general, i. e. a material which may be used as a binder if available in a specific form in the formation of wrinkles.
  • pectin or a derivative thereof is being mentioned in general, i. e. a material which may be used as a binder if available in a specific form in the formation of wrinkles.
  • BE-A-525 814 is completely silent.
  • the above object is achieved by using a specified amount of a specified substance as a binder.
  • a method of manufacturing wrinkled sheet tobacco by wetting a raw material powder containing tobacco with water, extruding the resultant wet powder through a gap between a pair of rollers, and separating sheet tobacco attached to the surface of one roller with a doctor knife, wherein one of the substances selected from those enumerated below is added to the raw material powder in an amount defined below.
  • the amount defined below is an amount based on the overall weight of the powder before wetting with water (i. e., the total weight of the raw material powder):
  • sheet tobacco having large wrinkles with a pitch of about 2 mm and a height of about 1 mm can be obtained.
  • Wrinkles formed by the method of the present invention are different from those formed by conventional methods in that small wrinkles are present in large wrinkles to provide a greater filling capacity, as shown in Fig. 2.
  • the method of the present invention does not require a special doctor knife, as in Japanese Patent Publication No. 48-5919, and allows formation of large wrinkles even upon considerable wear of the doctor knife.
  • Sheet tobacco prepared by the method of the present invention has excellent water resistance, and provides good taste when smoked, as will be described with reference to Examples to be described later. [Brief Description of Drawings]
  • Fig. 1 is a sectional view schematically showing the size and shape of sheet tobacco obtained by a conventional method:
  • Fig. 2 is a sectional view schematically showing the size and shape of sheet tobacco obtained by the method of the present invention:
  • Fig. 3 is a schematic diagram for explaining the method of the present invention. [Best Mode of Carrying Out the Invention]
  • a raw material powder containing tobacco such as tobacco waste
  • the raw material powder used in the present invention contains tobacco, such as tobacco waste or rib waste, a binder, and optionally additives such as a humectant, a reinforcing agent, and a water resistance agent. Water is added thereto in order to wet the raw material (i.e. , to provide a suitable water content).
  • the most important characteristic of the present invention is that a specified amount of the specified substance is used as the binder.
  • the following substances can be used as the binder herein:
  • a binder selected from those enumerated above must be used in a specified amount. More specifically, when substance (1) or (2) above is used, it must be used in an amount of 4 to 10% by weight based on the total weight of the raw material powder (i.e. , the total weight of the powder before addition of water). When anyone of substances (3) to (6) is used, it must be used in an amount of 4 to 11% by weight based on the above-mentioned total weight. When substance (7) is used, it must be used such that 4,4,6-triglucosaccharide polymer is 1.9 to 7.9% by weight, and sodium carboxymethyl cellulose is 1.3 to 3.2% by weight.
  • tobacco can be selected from various tobacco wastes, including leaf waste, cut waste, tobacco powder, rib waste, and winnower waste.
  • the raw material powder contains tobacco in an amount of 50 to 98%, and preferably 70 to 95%.
  • the raw material powder can also contain suitable amounts of a humectant, a reinforcing agent, a water resistance agent, and the like.
  • the humectant can, for example, be a mixture of propylene glycol and corn syrup (in a weight ratio of, e.g., 1 : 2).
  • the reinforcing agent can be, e.g., fibrillated pulp.
  • the water resistance agent can be, e.g., glyoxal or the like.
  • the wet raw material powder is prepared by mixing these respective components to provide a raw material powder and then adding water to the powder to obtain a suitable water content of the wet raw material powder.
  • the wet raw material powder has a water content of 30 to 70%, and preferably 40 to 60%.
  • wet raw material powder 2 thus prepared is extruded as a sheet from a gap between a pair of rollers 1, which rotate in opposite directions.
  • the peripheral speed of the rollers is 20 m/min or more, and, more preferably, 70 m/min or more.
  • the gap between rollers 1 is normally selected to be about 0.1 mm.
  • separated sheet 5 has large wrinkles, as shown in Fig. 2.
  • small wrinkles are formed in the large wrinkles to increase the filling capacity.
  • the wrinkled sheet tobacco manufactured by the method of the present invention has a filling capacity of 35 to 42 cm3 when tested by a filling capacity test described in Test Example 1 below. when a water resistance test, also described in Test Example 1, is performed, the sheet tobacco of the present invention has a shape retention property for 30 minutes or longer.
  • the wrinkled sheet tobacco prepared in this manner is cut and mixed with raw materials for, e.g., cigarettes.
  • Tables 1 and 2 The components shown in Tables 1 and 2 were mixed in the mixing ratios shown in the Tables. Water was added to each mixture to provide a wet raw material powder having a water content of 30%. Each wet powder was supplied to a gap between a pair of rollers rotating in opposite directions at a peripheral speed of 75 m/min. Each sheet tobacco attached to one roller was separated therefrom with a doctor knife, was placed on a belt conveyor, and was fed into a drier. Sheet tobaccos having a water content of 11% by weight and a thickness of 0.1 mm were thus prepared. The sheets were cut into widths of 0.8 mm and lengths of 10 mm to provide cut tobaccos.
  • the increase in water resistance of the sheet tobaccos obtained in the above manner was measured according to the following procedures.
  • One hundred and fifty milliliters of warm water at 30°C were poured into a petri dishes having a diameter of 20 mm.
  • the sheet tobaccos were cut into a circular form having a diameter of 30 mm and were placed in the respective petri dishes.
  • the petri dishes were shaken horizontally six times per minute at an amplitude of 16 mm five seconds for intervals of 5 seconds.
  • the time required for tearing the circular sheet taboccos into three or more pieces was measured, and is expressed in % with reference to the Control sheet tobacco.
  • the Control sheet tobacco had a water resistance (time) of 10 minutes.
  • the powder as a raw material for the control sheet tobacco and the control cut tobacco had the following composition: 54% of raw material waste tobacco, 35% of winnower waste, 3% of sodium carboxymethyl cellulose, 2% of glyoxal, 3% of propylene glycol, 3% of sorbitol, and water in an amount to provide a water content of 60%.
  • Tabel 1 when one of the starches is used as the binder in an amount of 4 to 10% by weight, many wrinkles like those shown in Fig. 2 can be formed, and the filling capacity increases by 5 to 23% over that of conventional sheet tobacco, although each different starch has a slightly different filling capacity-increasing degree. Water resistance is also increased by 80 to 210%. In contrast to this, when dialdehyde starch, etherified starch, or phosphate starch is used as the binder, no wrinkles are formed, filling capacity is lower than that of conventional sheet tobacco, and no increase in water resistance is observed.
  • Example 2 Six panelists smoked cut tobaccos of Example 2, Example 6, Example 10 and Example 14, and the Control cut tobacco, and evaluated the aroma, taste, peculiarity in taste, and stimulation in accordance with a ⁇ 3 point method.
  • the evaluation standards were as follows:
  • the tobaccos manufactured by the method of the present invention have qualities, such as aroma, taste, peculiarity in taste, or stimulation, that are equivalent to or better than those of conventional tobacco.
