Description

Heated cigarette slice 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

The heating non-burning tobacco product is a new-type product combining heating appliance and cigarette bullet, it is a "low-temp. cigarette" designed by using "heating only and non-burning" as thought, and utilizes special-purpose heating device to heat the treated cut tobacco and cigarette bullet to a certain temp., and heat the cigarette bullet to a degree sufficient for giving out smoke gas for smoking.

The cartridges of the heated non-combustible tobacco products are mainly divided into two types, namely a particle technology and a sheet technology. The particle technology has the advantages that the residues are some dry carbonized particles after the heating core is heated, so that the particles can be removed easily, but the particle technology has the defects of uneven heating, small smoke quantity, easy generation of burnt smell, inconsistent front and rear smoke quantity and incapability of keeping the fragrance of cigarettes. The sheet technology is that the herbal plant or tobacco-like component is crushed and mixed with natural fiber, and then added with adhesive and the like to be uniformly stirred, and the sheet product is prepared after constant-pressure drying. But the disadvantage is that the thin sheet is easy to absorb moisture, which affects the adaptability of the machine.

In order to solve the moisture absorption problem of the sheet, a moisture-proof layer is generally formed on the surface of the sheet in the prior art, such as a moisture-proof humectant disclosed in patent document with publication number CN113907409a for preventing moisture absorption of the tobacco sheet, and is characterized by comprising polyalcohol, beta-cyclodextrin and polyglucosamine (1-4) -2-amino-B-D glucose, and moisture absorption of the sheet is prevented by spraying the moisture-proof humectant. Another example of such a heated cigarette core material is disclosed in the publication CN114009826a and a method of making the same, comprising the steps of: pretreatment of a fuming agent, configuration of perfume, pretreatment of sizing material, preparation of substrate slurry, treatment of powder material, forming of a substrate, powder spraying, rolling of a sheet, film coating and drying forming. The porous solid adsorbent is added into the smoke agent, and the smoke agent is mixed with the glue system to be embedded in the base material slurry, so that the moisture absorption problem of the prepared smoke core material can be effectively solved by matching with the film coating process.

In the scheme, on one hand, the moisture-proof layer has the problem of easy falling off, and the long-term preservation effect of the thin sheet is affected; on the other hand, the sheet itself has the problem of low tensile strength, and the material used for the moisture-proof layer does not positively influence the tensile strength of the sheet.

Disclosure of Invention

The present invention has been made to solve the above problems, and provides a heated cigarette sheet and a method for manufacturing the same.

The technical scheme for solving the problems is that the invention firstly provides a heating cigarette slice which comprises water, an adhesive, a smoke agent, tobacco powder, wood pulp, tea fruit pulp and animal fat, wherein the tea fruit pulp comprises tannin and tea saponin, and the animal fat comprises glyceride.

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

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

The wood pulp is mainly used for providing supporting fibers for the thin sheet and ensuring the basic strength of the thin sheet, and is generally prepared by chemically pulping and physically pulping plant raw materials, wherein the plant raw materials can be woody plants such as needle wood, broad-leaved wood and the like, can also be herbaceous plants such as Chinese alpine rush, tobacco stems and the like, and can be directly purchased in the market.

The tobacco powder is used for providing traditional cigarette aroma for the thin sheet and also providing a certain amount of supporting fiber, and is usually prepared by directly fermenting tobacco leaves and then freezing and crushing the tobacco leaves.

The adhesive is used for combining the solid components, is preferably a nontoxic and non-pungent odor adhesive, and as a preferable mode of the invention, the adhesive comprises one or more of guar gum, chitosan, sodium carboxymethyl cellulose and pectin.

Water is generally used to dilute the above components for subsequent sheeting.

In order to solve the moisture absorption problem and the low tensile strength problem of the thin sheet, tea fruit pulp and animal fat are creatively added into the thin sheet raw material.

The tea fruit pulp is mainly prepared by extracting tea fruits under the condition of a solvent, wherein the tea fruits comprise outer shells and tea seeds therein, the shells contain higher-content tannin, and the tea seeds contain higher-content tea saponin and vegetable oil. The solvent for extracting the tea fruits is not limited, and as the preferable choice of the invention, a mixed solvent of propylene glycol and water is selected. The ratio of the propylene glycol to the water is not limited, and the solvent preferably includes 10 to 60 parts by mass of propylene glycol and 20 to 90 parts by mass of water. The ratio of the amount of the tea fruit to the amount of the solvent is not limited, and in order to improve the extraction yield, it is preferable to mix 10 to 80 parts by mass of the tea fruit and 10 to 80 parts by mass of the solvent at the time of extraction.

The main components of animal fat are triglycerides 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, first, the tea fruit pulp and the animal fat can respectively act: tea fruit pulp: the wood pulp cellulose is subjected to condensation reaction with active hydrogen on tannin molecules through aldehyde groups (bleaching agents used in the process of preparing the wood pulp oxidize cellulose hydroxyl groups into aldehyde, general acid groups and the like), and the tannin is anchored on the fibers through covalent bonds, so that a hydrogen bond connection structure between the cellulose is replaced, the hydrophobicity of the sheet is improved, moisture absorption is avoided, and the bonding strength between the fibers, namely the tensile strength of the sheet is improved to a certain extent; the vegetable oil can form a layer of hydrophobic film on the surface of the flake through the hydrophobic group, so that the hydrophobic property is improved to realize moisture resistance, and the internal stress of the flake can be improved to increase the tensile strength of the flake. Animal fat: the hydrophobic property is also improved by the hydrophobic group, and the internal stress is improved.

Second, tea fruit pulp and animal fat may act synergistically: because of the existence of water and animal fat, before the sheet is formed, the slurry obtained by mixing all the raw materials is an oil-water mixture, and the tea saponin has good interfacial activity, can help the emulsification of the oil-water mixture, improves the uniformity of the slurry, and improves the moisture-proof uniformity of the sheet. Meanwhile, the tea saponin can also self-assemble to form micelles, the micelles form ordered fibrous aggregates in an oil-water interface in a self-assembly way, and as the tea saponin molecules are adsorbed perpendicular to the interface, the tea saponin has extremely high elastic modulus and viscosity, shows viscoelastic behavior, and improves the tensile strength of the thin sheet through the viscoelasticity. And glyceride is also an amphipathic molecule, glyceride in the oil phase tends to be adsorbed on the surface of oil drops, and at a certain concentration, glyceride crystals can pierce the fiber interface film of the tea saponin and enter the water phase, at the moment, glyceride part participates in interface formation, the glyceride and the tea saponin cooperatively reduce interfacial tension, formed emulsion drops are smaller, the accumulation is tighter, the strength of the constructed three-dimensional network structure is larger, and therefore the mechanical property is improved.

In the process, the ratio of the tea fruit pulp to the animal fat has a certain influence on the final hydrophobicity and tensile strength, and the excessive use of the animal fat and the excessive use of glyceride can influence the viscoelasticity of the fiber interface film and the tensile strength of the thin sheet; animal fat and oil are too low in dosage, so that the dosage of glyceride is too low, on one hand, the hydrophobicity is insufficient, and on the other hand, the glyceride is insufficient to pierce the fiber interface membrane, and the synergistic effect of the glyceride and the tea saponin is affected. Preferably, the animal fat is used in an amount of 3-5wt% of the tea fruit pulp.

The content of other raw materials also has a certain influence, and the preferred part of the invention is that the heating cigarette slice comprises 10-60 parts of tobacco powder, 5-60 parts of tea fruit pulp, 10-40 parts of water, 0.2-5 parts of adhesive, 10-60 parts of fumigant, 1-4 parts of wood pulp and 0.5-4 parts of animal fat.

In order to further improve the moisture absorption problem and the tensile strength of the sheet, the tobacco powder is preferably prepared by baking a mixture of pulp and fermented tobacco leaves at 140-160 ℃ and pulverizing.

The traditional tobacco powder only comprises tobacco leaves after fermentation, and fruit pulp is added for co-baking. The fruit pulp is mainly prepared by extracting fruit raw materials under the condition of a solvent, and contains saccharide compounds such as fructose and the like. The method can reduce harmful components in tobacco leaves by fermenting the tobacco leaves, and can obtain amino acid by fermenting. The amino acid can generate Maillard reaction with the saccharide compound at a certain temperature, so that the aroma of the flake is further improved, and the miscellaneous gas and the irritation are reduced; and the obtained product comprises furfural, can be covalently condensed with tannin in tea fruit pulp, improves the hydrophobicity and tensile strength of the flake, and has better compatibility of tobacco powder and wood pulp under the intermediate action of tannin.

In view of the formation amount of Maillard reaction products, as a preferred aspect of the present invention, the tobacco powder comprises 10-99 parts by mass of fermented tobacco leaves and 1-30 parts by mass of fruit pulp.

The pulp may be a solvent extract of any fruit material, such as apple pulp, jujube pulp, coconut pulp, etc., and preferably, coconut pulp is used in the present invention. Because 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 moisture absorption problem of the slice can be further improved by utilizing the hydrophobic group in the coconut oil. The solvent for extracting the fruit pulp is not limited, and preferably comprises 10-50 parts by mass of propylene glycol and 30-80 parts by mass of water. The ratio of the fruit to the solvent is not limited, and preferably, the fruit is mixed with 10 to 60 parts by mass and 20 to 90 parts by mass of the solvent during extraction.

The fermented tobacco leaves can be the product of fermenting fresh tobacco leaves in any mode, and are mixed fermentation products of tobacco leaves and cocoa pulp as the preferable mode of the invention. The color of the tobacco leaves can be regulated by fermenting the tobacco leaves and the cocoa pulp together, so that the milk flavor and the bean flavor of the tobacco leaves are improved. Preferably, 10-80 parts of cocoa pulp and 30-90 parts of tobacco leaf are mixed and fermented according to parts by mass.

It is yet another object of the present application to provide a method of manufacturing a heated cigarette sheet comprising the steps of:

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

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

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

The flakes themselves need to have a moisture content to avoid excessive drying of the flakes and to be brittle, and preferably according to the invention, the flakes are dried to a moisture content of 7-12% after molding.

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

The invention has the beneficial effects that:

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

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

[ Performance detection ]

The tensile strength of the sheets prepared in examples and comparative examples was measured according to the measurement method 6 in YC/T16-2014 reconstituted tobacco, and the measurement results are shown in Table 1 below.

The sheets prepared in examples and comparative examples were placed in the same environment, and the moisture was measured at different time periods, and the measurement results are shown in table 1 below.

Table 1.

As shown in table 1, it can be seen from the comparison of examples and comparative examples that the combination of tea fruit pulp and animal fat is effective in improving the tensile strength of the sheet and reducing the moisture absorption of the sheet. Meanwhile, it can be seen from a comparison of example 2 and examples 1 and 3 that although the moisture absorption of the sheet is improved with an increase in the amount of animal fat, an excessively high amount of animal fat affects the tensile strength of the sheet. By comparing example 1 with examples 4 and 5, it can be seen that co-baking the pulp with the fermented tobacco leaves also increases the tensile strength and reduces the moisture absorption to some extent. From a comparison of example 1 and example 6, it can be seen that coconut pulp has better moisture absorption resistance than ordinary fruit pulp. From a comparison of example 1 with examples 7 and 8, it can be seen that stirring also affects to some extent the formation of the thick stock emulsion and thus the properties of the flakes formed by the thick stock emulsion.

The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
