Description

Heating cigarette sheet and manufacturing method thereof

Technical Field

The invention relates to the technical field of heating non-combustible tobacco products, in particular to a heating cigarette sheet and a manufacturing method thereof.

Background

A heating non-combustion tobacco product is a novel product combining a heating appliance and a cigarette cartridge, and is a low-temperature cigarette designed by taking 'heating non-combustion' as the idea, wherein the processed tobacco shreds and the cigarette cartridge are heated to a certain temperature by a special heating device, and the cigarette cartridge is heated to a degree enough to emit smoke for people to absorb.

The tobacco product cartridge which can not burn by heating is mainly divided into two types, namely a particle technology and a sheet technology. The particle technology has the advantages that residues after the heating core is heated are some dry carbonized particles which can be easily removed, but the particle technology has the defects of uneven heating, small smoke amount, easy generation of burnt flavor, inconsistent front and back smoke amount and incapability of keeping the fragrance of cigarettes. The slice technology is that the herbaceous plant or the tobacco-like component is crushed and mixed with the natural fiber, the adhesive and the like are added and stirred evenly, and the slice product is prepared after constant pressure drying. But the disadvantage is that the thin slice is easy to absorb moisture, which affects the adaptability of the machine.

In order to solve the problem of moisture absorption of the sheet, it is common in the prior art to form a moisture-proof layer on the surface of the sheet, such as a moisture-proof humectant for preventing moisture absorption of tobacco sheets disclosed in patent document CN113907409A, which is characterized by comprising polyhydric alcohol, beta-cyclodextrin and polyglucosamine (1-4) -2-amino-B-D glucose, and preventing moisture absorption of the sheet by spraying the moisture-proof humectant. For another example, patent document CN114009826A discloses a material for heating cigarette core and a preparation method thereof, which comprises the following steps: the method comprises the following steps of smoke agent pretreatment, spice preparation, sizing material pretreatment, base material slurry preparation, powder material treatment, base material forming, powder spraying, sheet rolling, film laminating, drying and forming. The porous solid adsorbent is added into the smoke agent, the smoke agent is mixed with a glue system to embed the smoke agent in the base material slurry, and the moisture absorption problem of the prepared cigarette core material can be effectively solved by matching with the film coating process treatment.

In the scheme, on one hand, the moisture-proof layer is easy to fall off, so that the long-term storage effect of the sheet is influenced; on the other hand, the sheet itself has a problem of low tensile strength, and the material used for the moisture barrier does not have a positive influence on the tensile strength of the sheet.

Disclosure of Invention

The present invention is to solve the above problems, and provides a heated cigarette sheet and a method for producing the same.

According to the technical scheme for solving the problems, firstly, the heating cigarette sheet is provided, and comprises water, an adhesive, a smoke agent, tobacco powder, wood pulp, tea fruit pulp and animal oil, wherein the tea fruit pulp comprises tannin and tea saponin, and the animal oil comprises glyceride.

Wherein, water, adhesive, smoke agent, tobacco powder and wood pulp are common components of the slice.

The fuming agent is used for atomizing and generating smoke when being heated, and can be selected from common fuming agents such as propylene glycol and glycerol. Preferably, the smoke agent comprises 10-60 parts of propylene glycol and 40-90 parts of glycerol by mass.

The wood pulp is mainly used for providing supporting fibers for the slices and ensuring the basic strength of the slices, and is generally prepared by chemically pulping and physically pulping plant raw materials, wherein the plant raw materials can be woody plants such as coniferous wood, broadleaf wood and the like, can also be herbaceous plants such as Chinese alpine rush, cabo and the like, and can be directly purchased on the market.

The tobacco powder is used for providing the traditional cigarette fragrance for the slices and also providing certain supporting fiber, and is prepared by directly fermenting tobacco leaves and then freezing and crushing the fermented tobacco leaves.

The adhesive is used for combining the solid components, preferably is a nontoxic adhesive without pungent smell, and preferably comprises one or more of guar gum, chitosan, sodium carboxymethylcellulose and pectin.

Water is generally used for diluting the components, so that the components can be conveniently made into sheets in a subsequent papermaking process.

In order to solve the problems of moisture absorption and low tensile strength of the flakes, tea pulp and animal fat are creatively added to the raw materials of the flakes.

The tea fruit pulp is mainly obtained by extracting tea fruits under the condition of a solvent, wherein the tea fruits comprise outer shells and tea seeds in the outer shells, the shells contain high-content tannin, and the tea seeds contain high-content tea saponin and vegetable oil. The solvent for extracting the tea fruit is not limited, and a mixed solvent of propylene glycol and water is preferably used in the present invention. The amount ratio of propylene glycol to water is not limited, and as a preferred aspect of the present invention, the solvent comprises, by mass, 10 to 60 parts of propylene glycol and 20 to 90 parts of water. The ratio of the amount of the tea fruit to the solvent is not limited, and in order to improve the extraction rate, it is preferable in the present invention that 10 to 80 parts by mass of the tea fruit and 10 to 80 parts by mass of the solvent are mixed at the time of extraction.

The animal fat and oil mainly contains triglyceride of palmitic acid and stearic acid. Preferably, the animal fat comprises one or more of lard, beef tallow and mutton tallow.

When the tea fruit pulp and the animal fat are mixed for use, firstly, the tea fruit pulp and the animal fat can respectively act: in the tea fruit pulp: the wood pulp cellulose is subjected to condensation reaction with active hydrogen on tannin molecules through aldehyde groups (in the process of preparing wood pulp, the used bleaching agent oxidizes cellulose hydroxyl into groups such as aldehyde, ketone, acid and the like), and tannin is anchored on the fibers through covalent bonds to replace a hydrogen bond connection structure between the cellulose, so that the hydrophobicity of the sheet is improved, the moisture absorption is avoided, and the bonding strength between the fibers is improved to a certain extent, namely the tensile strength of the sheet is improved; the vegetable oil can form a hydrophobic film on the surface of the sheet through the hydrophobic groups of the vegetable oil, so that the hydrophobic property is improved to realize moisture resistance, and the internal stress of the sheet can be improved to increase the tensile strength of the sheet. In the animal fat and oil: the hydrophobic property is improved through the hydrophobic group, and the internal stress is improved.

Second, the tea fruit pulp and animal fat can act synergistically: due to the existence of water and animal fat, before the sheet is formed, slurry obtained by mixing all the raw materials is an oil-water mixture, and the theasaponin has good interfacial activity, can help the oil-water mixture to be emulsified, improves the uniformity of the slurry and improves the moisture-proof uniformity of the sheet. Meanwhile, the theasaponin can also be self-assembled to form micelles, the micelles can be self-assembled at an oil-water interface to form an ordered fibrous aggregate, and theasaponin molecules are adsorbed perpendicular to the interface, so that the tea saponin has extremely high elastic modulus and viscosity, shows a viscoelastic behavior, and improves the tensile strength of the sheet through viscoelasticity. The glyceride is also an amphiphilic molecule, glyceride in the oil phase tends to be adsorbed to the surface of oil drops, glyceride crystals can pierce fiber interface membranes of tea saponin to enter the water phase under a certain concentration, the glyceride part participates in interface formation, the glyceride and the tea saponin synergistically reduce the interface tension, formed emulsion drops are smaller, the stacking is tighter, the strength of the constructed three-dimensional network structure is higher, and therefore the mechanical property is improved.

In the process, the dosage of the tea fruit pulp and the animal fat has certain influence on the finally expressed hydrophobicity and tensile strength, and the dosage of the animal fat is too high, so that the dosage of glyceride is too high, the viscoelasticity of a fiber interface film is influenced, and the tensile strength of the sheet is influenced; the dosage of the animal fat is too low, so that the dosage of the glyceride is too low, on one hand, the hydrophobicity is insufficient, and on the other hand, the glyceride is not enough to pierce a fiber interface membrane, so that the synergistic effect of the glyceride and the tea saponin is influenced. Preferably, the animal fat is 3-5wt% of the tea fruit pulp.

The content of other raw materials also has certain influence, and as the optimization of the invention, the heating cigarette sheet comprises 10 to 60 parts of tobacco powder, 5 to 60 parts of tea fruit pulp, 10 to 40 parts of water, 0.2 to 5 parts of adhesive, 10 to 60 parts of smoke agent, 1 to 4 parts of wood pulp and 0.5 to 4 parts of animal fat according to the parts by mass.

In order to further improve the moisture absorption problem and tensile strength of the flakes, in the present application, as a preferred aspect of the present invention, the tobacco powder is prepared by baking a mixture of fruit pulp and fermented tobacco leaves at 140 to 160 ℃ and then pulverizing the mixture.

The traditional tobacco powder only comprises fermented tobacco leaves, and fruit pulp is added in the application for co-drying. The fruit pulp is mainly extracted from fruit raw materials under the condition of solvent, and contains saccharide compounds such as fructose and the like. The method can reduce harmful ingredients in tobacco leaves and simultaneously ferment to obtain amino acid by fermenting the tobacco leaves. The amino acid and the carbohydrate can generate Maillard reaction at a certain temperature, so that the fragrance of the slices is further improved, and the miscellaneous gas and the irritation are reduced; the obtained product including furfural can be covalently condensed with tannin in tea fruit pulp, so as to improve hydrophobicity and tensile strength of the sheet, and the compatibility of tobacco powder and wood pulp is better under the intermediary action of tannin.

In view of the amount of the Maillard reaction product, the tobacco powder preferably comprises 10 to 99 parts by mass of the fermented tobacco leaves and 1 to 30 parts by mass of the fruit pulp.

The fruit pulp can be solvent extract of any fruit raw material, such as apple pulp, jujube pulp, coconut pulp and the like, and coconut pulp is preferably used in the invention. As the oil content of coconut meat is 35%, the oil is rich in capric acid, palmitic acid, lauric acid, oleic acid, fatty acid and free fatty acid, and the hydrophobic group in coconut oil can be utilized to further improve the moisture absorption problem of the slices. The choice of the solvent for extracting the fruit pulp is not limited, and as the optimization of the invention, the solvent comprises 10 to 50 parts of propylene glycol and 30 to 80 parts of water by mass. The amount ratio of the fruit to the solvent is not limited, and as a preferable aspect of the present invention, 10 to 60 parts by weight of the fruit and 20 to 90 parts by weight of the solvent are mixed at the time of extraction.

The fermented tobacco leaves can be products of fresh tobacco leaves fermented in any way, and are preferably mixed fermentation products of the tobacco leaves and cocoa pulp. The tobacco leaves and cocoa pulp are fermented together to adjust the color of the tobacco leaves uniformly and increase the milk fragrance and bean fragrance of the tobacco leaves. Preferably, 10 to 80 parts by mass of cocoa pulp and 30 to 90 parts by mass of tobacco leaf are mixed and fermented.

It is a further object of the present application to provide a method of making a heated cigarette sheet comprising the steps of:

s1, uniformly mixing tobacco powder, tea fruit pulp, water, an adhesive, a smoke agent, wood pulp and animal fat according to the mass parts, and stirring at 50-60 ℃ to obtain thick pulp;

s2, uniformly spraying the thick slurry on a steel belt through a slit of tape casting equipment, forming and drying to obtain a sheet.

In the application, the thick slurry is prepared by stirring at a specific temperature range of 50-60 ℃ to promote the stable forming of the oil-water emulsion, so that the subsequent hydrophobicity and tensile strength are ensured.

The sheet itself needs to have a certain moisture content to avoid the sheet from being too dry and fragile, and as a preferable aspect of the present invention, the sheet is obtained by drying the sheet after molding until the moisture content is 7 to 12%.

As a preferred aspect of the present invention, the tobacco powder is prepared by the steps of: mixing fresh cocoa pulp and tobacco leaf, and fermenting at 40-50 deg.C; taking out the fermentation product, and baking at 90-110 deg.C until the water content is 10-20% to obtain fermented tobacco leaf; mixing the fermented tobacco leaves and fruit pulp, baking at 140-160 deg.C until the water content is 4-7%, pulverizing, and sieving to obtain tobacco powder.

The invention has the beneficial effects that:

1. according to the application, the moisture absorption problem of the sheet is effectively improved and the tensile strength of the sheet is improved by adding tea fruit pulp and animal fat in the raw material of the sheet.

2. In this application, through the modified traditional tobacco powder of pulp, can also cooperate the use of tea pulp in order to further improve the sheet moisture absorption problem and improve tensile strength when improving the suction taste of sheet, can also improve the compatibility of tobacco powder and wood pulp in addition.

[ PROPERTIES DETECTION ]

The tensile strength test was carried out on the sheets obtained in examples and comparative examples according to the test method of clause 6 in YC/T16-2014 reconstituted tobacco, and the test results are shown in Table 1 below.

The sheets obtained in the examples and comparative examples were placed in the same environment, and moisture was measured at different standing times, and the results of the measurements are shown in table 1 below.

Table 1.

As shown in Table 1, by comparing the examples with the comparative examples, it can be seen that the combination of tea fruit pulp and animal fat and oil is effective in improving the tensile strength of the sheet and reducing the moisture absorption of the sheet. Meanwhile, by comparing example 2 with examples 1 and 3, it can be seen that although the moisture absorption of the sheet improves with the increase in the amount of animal fat, the tensile strength of the sheet is affected by the excessively high amount of animal fat. By comparing example 1 with examples 4 and 5, it can be seen that co-baking the pulp with fermented tobacco leaves also improves tensile strength and reduces moisture absorption to some extent. By comparing example 1 with example 6, it can be seen that coconut pulp has better moisture resistance than regular fruit pulp. By comparing example 1 with examples 7 and 8, it can be seen that the stirring also influences the forming of the thick paste emulsion to a certain extent, and thus influences the properties of the sheets formed from the thick paste emulsion.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
