According to another preferred embodiment of the invention, the water content of the flue gas bound section is 2.0 to 4.0% by weight.
The present invention will be described in more detail below.
The invention relates to a plant silk type binary structure heating non-combustible product.
The plant silk type heating non-combustible product with the binary structure is formed by wrapping a smoke generating section and a smoke binding section which are sequentially made of plant silk materials containing smoke agents through outer layer wrapping paper, and the specific structure is shown in figure 1, wherein 1-the smoke generating section is shown in the figure; 2-a flue gas binding section; 2-1-straight through hole; 3-wrapping paper; or the plant silk type binary structure heating non-combustible product is obtained by sequentially loading into a tube made of silica gel, paper or high molecular material with temperature resistance higher than 300 deg.C, and the specific structure is shown in figure 2, wherein figure 1-smoke generation section; 2-a flue gas binding section; 2-1-straight through hole; 3-1-tube; the smoke binding section is a suction end.
According to the invention, the main function of the plant silk material in the heat-not-burn product is to provide fragrance to the product, and the plant silk material is a flue-cured tobacco, tobacco stem, sun-cured tobacco or burley tobacco shred smoking material and a mint, tea, betel nut or cocoa non-tobacco shred smoking material.
The tobacco shred smoking materials are finished tobacco raw materials commonly used in the prior art, or expanded tobacco leaves or expanded tobacco stems processed by the prior expansion processing method, the processed tobacco raw materials have increased volume and increased pores, and can absorb more smoking agents and spice substances, and the specific situation is shown in document CN110638083A, the invention name of which is 'an efficient preparation method of expanded tobacco shreds', CN 103169150B, the invention name of which is 'a preparation method of expanded tobacco stems'.
Non-tobacco shredded smoking materials such as mint are currently marketed products which can be used as such or after the same expansion treatment.
According to the invention, the plant silk material is formed by rolling tobacco silk or non-tobacco silk with the width of 0.5-3.0 mm, and the filling rate of the plant silk material in a smoking section is 40-80%.
In the present invention, the filling rate is understood to be the ratio of the volume of the plant silk material to the volume of the smoking segment, expressed as a percentage.
When the filling rate is in the range, if the width of the filamentous smoking material is less than 0.5mm, broken filaments are easy to agglomerate in the rolling process, and the suction resistance is influenced; if the width of the filamentous smoking material is more than 3.0mm, the porosity of the rolled material is high, the heating is insufficient, and the smoking amount is influenced.
When the width of the filamentous smoking material is within the range, if the filling rate is lower than 40%, the cut tobacco falls off to influence the product quality; if the filling rate is higher than 80%, the filling amount is too large, which causes too high suction resistance and affects the suction experience.
The primary function of the smoke agent in the heated non-combustible article is to provide the smoke required when smoking the heated non-combustible article of the invention.
According to the invention, the said smoke agent is one or more smoke agents selected from glycerol, propylene glycol, glycerol diacetate or glycerol triacetate, all of which are currently marketed products, such as glycerol diacetate sold under the name diacetate by Hubei Hengheng technology Co., Ltd, glycerol triacetate sold under the name triacetate by Jiangsu Caesalpe Biotech Co., Ltd.
According to the invention, the content of the smoke agent is 10-50% of the weight of the plant silk material. If the addition amount of the smoke agent is less than 10%, the smoke amount of people in smoking is less, and smoking experience is influenced; if the addition amount of the smoke agent is more than 50 percent, the mobility of the tobacco shreds and the non-tobacco shreds is poor in the processing process, and the tobacco shreds and the non-tobacco shreds are difficult to process to obtain products meeting quality requirements.
According to the invention, the main function of the smoke binding section in the non-combustible heating product is that the smoke binding section has enough area for heat exchange with smoke and enough heat capacity, and has the functions of cooling and guiding, so as to reduce the temperature of the smoke and guide the smoke for being sucked by consumers.
According to the invention, the smoke binding section is a cylinder made of silicon rubber, polyethylene, polypropylene, vinylidene chloride, polylactic acid, polyurethane, cellulose acetate or paper material, and a through hole parallel to the longitudinal axis of the cylinder is arranged in the cylinder or between the cylinder and the outer layer wrapping paper.
The silicone, polyethylene, polypropylene, vinylidene chloride, polylactic acid, polyurethane, cellulose acetate or paper materials used in the present invention are all commonly used in the art and are currently marketed products, such as silicone sold under the trade name silicone rubber by Balginia Yunnanensis Biotech, Inc., vinylidene chloride sold under the trade name PVDC by Guangzhou Xin porcelain environmental protection materials, Inc., cellulose acetate sold under the trade name cellulose acetate by Shaoxing-like textile technology, Inc.
According to the invention, the water content of the flue gas binding section is 2.0-4.0% by weight. If the water content of the smoke binding section is lower than 2.0%, the cooling effect is not ideal, and the suction experience is influenced; if the water content of the smoke binding section is higher than 4.0%, the smoking material of the smoking section is easy to absorb moisture, and the product quality is affected, so that the water content of the smoke binding section is suitable to be 2.0-4.0%. In the present invention, the water content is measured according to GB/T23357-2009 Karl Fischer method for measuring the moisture of tobacco and tobacco products.
In the invention, the side of the cross section of the smoke binding section is circular, zigzag or wavy; the edge of the cross section of the through hole is circular, zigzag or wavy. Of course, the cross section of the flue gas confinement section and the cross section of the through hole can be in other regular shapes or irregular shapes, and one can select the shape according to actual conditions, which will not cause any difficulty for the person skilled in the art.
In the invention, when the through hole is positioned in the middle of the flue gas binding section, the distance between the wall of the through hole and the outer wall of the flue gas binding section is 1-3 mm. In the present invention, when the edge of the through hole cross section is non-circular, this distance is understood to be the shortest distance between the wall of the through hole and the outer wall of the flue gas confinement section.
According to the invention, on the cross section of the smoke binding section, the ratio of the area of the through holes to the area of the non-through holes is 0.3-2.0. If the ratio of the area of the straight-through hole to the area of the non-straight-through hole is less than 0.3, the area of the straight-through hole is smaller, the suction resistance is large in the suction process, and the smoke concentration is insufficient; if the ratio of the area of the straight through hole to the area of the non-straight through hole is larger than 2.0, the area of the straight through hole is too large, the material amount of a smoke bounding section is small, and the heat capacity of the smoke bounding section is insufficient, so that the smoke temperature and the temperature of a lip end of a smoke bomb are higher, and the smoking experience of people is influenced. Preferably, the ratio of the area of the through holes to the area of the non-through holes is 0.5 to 1.8, and more preferably, the ratio of the area of the through holes to the area of the non-through holes is 0.8 to 1.6.
The smoke binding section is prepared by adopting an extrusion method or an injection molding method, and concretely, the extrusion method refers to CN 102642291B and the invention name of 'preparation process of large-diameter silicone tube'; for example, CN 107639787 a, entitled "a process for forming a silicone layer on the surface of a glass bottle by injection molding" is referred to as an injection molding method.
In the present invention, the outer-layer wrapping paper used is a common forming paper generally used in the art; the tube is made of silica gel, paper or high polymer material which can resist the temperature higher than 300 ℃, and the paper is cellulose paper, kraft paper, laminating paper and coated paper, for example; the polymer material is, for example, polyphenylene, polyimide, graphene polymer, or the like; these are commercially available products, for example, cellulose paper sold under the trade name of molding paper by the development ltd of the science and technology industry of engineth, yun, a coated paper sold under the trade name of water-and oil-barrier paper by the ltd of the paper industry of xu, polyphenylene sold under the trade name of PPSU by the ltd of majeri, and a graphene polymer sold under the trade name of graphene composite material by the cely leixi colloidal graphite factory.
The average smoke temperature, smoke concentration and sensory evaluation method are specifically described below.
The original-flavor cigarette cartridges produced in Feimo International and heated non-burning HHETs are selected as comparison cigarette cartridges, and according to the standards of GBT 19609-.
The average smoke concentration is measured by using the device by adopting a light transmission method under the conditions that the wavelength lambda of a laser light source is 630 mu m and the detection optical path is 4 cm;
and (3) pumping procedure: selecting iQOS smoking set produced by Felmo International, wherein the smoking program is that the equipment enters a smoking state after the heater finishes preheating, the smoking capacity of each port is 35ml, the smoking time is 2s, the flow rate of the smoking air flow is 17.5ml/s, the smoking interval is 13s, the total number of the smoking ports is 16, and the total smoking working time is 240 s;
and (3) temperature measurement: measuring the mainstream smoke temperature and the lip end temperature of the smoke cartridge by using a K-type thermocouple temperature detector;
smoke concentration index determination: the light transmission method for measuring the smoke concentration is a non-contact measuring method, when a light source passes through an aerosol medium, light beams and aerosol particle spherical surfaces generate scattering and refraction and the absorption effect of particles on the light, so that the transmission light intensity of a laser light source penetrating through aerosol smoke can be attenuated, when the aerosol concentration is higher, the transmission light intensity attenuation effect is more obvious, and when the aerosol concentration is lower, the transmission light intensity attenuation effect is weaker. The ratio of the intensity of the incident light to the intensity of the absorbed light under the specified detection conditions is called the extinction ratio, which is the measured smoke density index expressed in%.
