technical field

The invention relates to the field of heat-not-burn tobacco, in particular to a method for manufacturing a heat-not-burn smoking body.

Background technique

Heat-not-burn cigarettes are a special tobacco product being developed in recent years. They are heated by electric heating or other heating methods to release the aroma components and other substances in tobacco products. Pyrolysis at 900°C produces a large amount of harmful components. While consumers are satisfied, the harm to the body is reduced, and the pollution of environmental flue gas is also reduced.

The smoking body part of current heat-not-burn cigarettes is usually made of synthetic tobacco sheets. The main materials of the tobacco sheet are tobacco stems, lower tobacco leaves and other low-grade tobacco materials that are beaten and re-pressed, and contain a smoking agent. Artificial flakes are non-natural and have a certain thickness when manufactured to maintain rigidity. In addition, the tobacco sheet has strong water absorption, can effectively adhere to the atomizing agent, is resistant to heating, and has long-lasting and stable smoking. However, it is precisely because of the strong rigidity and poor elasticity of the tobacco sheet that a strong reaction force is generated when the heating needle or heating sheet of a general smoking device is inserted, which adversely affects the life of the smoking device. The situation of breakage and breakage of the heating plate after being inserted and pulled out for many times has virtually increased the manufacturing cost of the smoking set and reduced the satisfaction of consumers.

In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

The manufacturing method of the heat-not-burn smoking body of the present invention will be described below with reference to FIG. 1, which is a schematic diagram of the steps of the method for manufacturing a smoking body, showing the tobacco sheet 4.1, the shredded tobacco 4.2 and the wrapping layer 2, and showing the state A ~ Manufacturing process of state D. The manufacturing method of the present invention comprises the following steps: (1) preparing a tobacco sheet 4.1, shredded tobacco 4.2 and a wrapping layer 2; (2) laying the tobacco sheet 4.1 on the wrapping layer 2 along a first direction to form a tobacco sheet layer; ( 3) place the shredded tobacco 4.2 on the tobacco sheet layer along the first direction, and make the shredded tobacco 4.2 in the middle of the tobacco sheet layer along the second direction, wherein the first direction is perpendicular to the second direction; (4) pass the wrapping layer 2 The tobacco sheet 4.1 is rolled and formed along the second direction, so that the tobacco sheets are arranged in an orderly bundle, the shredded tobacco is located inside the tobacco sheet, and the wrapping layer wraps the tobacco sheet to form a columnar smoking body. The first direction is, for example, the x-direction in state C in FIG. 1 , and the second direction is, for example, the y-direction in state C in FIG. 1 . The first direction may also be understood as the length direction of the tobacco sheet layer, and the second direction may be understood as the width direction of the tobacco sheet layer. The wrapping layer 2 is rolled in the second direction so that the tobacco sheet 4.1 maintains its own elongated length and is gathered together. The shredded tobacco 4.2 is placed on the tobacco sheet layer in a first direction such that the shredded tobacco 4.2 extends from one end of the tobacco sheet 4.1 to the other end in the first direction. In addition, the shredded tobacco 4.2 is placed in the middle of the tobacco sheet layer along the second direction, so that the shredded tobacco 4.2 is located in the radial middle area of the smoking body 4 after rolling, and the tobacco sheet 4.1 wraps the shredded tobacco 4.2.

In this implementation, the tobacco sheet layer may be a layer of tobacco sheets formed by flattening the tobacco sheets 4.1, or may be multiple layers, or may also be formed by unevenly stacking tobacco sheets, which is not limited in the present invention.

Regarding step (2), the laying of the tobacco sheet on the wrapping layer can be accomplished by using an existing unfolding device. Regarding step (3), for the placement of the shredded tobacco, a container containing shredded tobacco can be used, and the container is moved along the first direction to sprinkle the shredded tobacco to the middle position of the tobacco sheet layer, and is removed from the tobacco sheet layer along the first direction. Sprinkle one end to the other. Alternatively, keep the container still, place the container above the tobacco sheet layer and in the middle of the tobacco sheet layer along the second direction, and drive the tobacco sheet layer and the wrapping layer to move as a whole along the first direction through the conveyor belt, so as to complete the crushed tobacco placement. Regarding step (4), a tobacco rod forming device can be used for forming and rolling. Further, the tobacco rod forming device contains a bell mouth. In this embodiment, the tobacco sheet 4.1 and the wrapping layer 2 of the shredded tobacco 4.2 are transported to the bell mouth together, and enter from the large mouth of the bell mouth and exit from the small mouth. For example, the bell mouth shown in FIG. 9 is connected with the tobacco sheet 4.1 and the wrapping layer 2 of the shredded tobacco 4.2 together from the A port into the tobacco rod forming device, and then out from the B port. The tobacco sheet 4.1 is tightened through the bell mouth and the wrapping of the wrapping layer 2 is completed. During the rolling process, glue can be applied to the side edges of the wrapping layer 2 so that the butt joints of the wrapping layer 2 are bonded. Then through drying, extrusion molding.

The tobacco sheet of the invention belongs to an artificial processed sheet, which is made by the thick pulp method or the papermaking method, and is mainly formed by beating tobacco materials such as tobacco stems and lower tobacco leaves, and then re-pressing. In the process of beating and making the material, the original veins and loose pores of the tobacco leaves will be destroyed to form relatively dense flakes. As a heat-not-burn smoking body, atomizing agents such as glycerin and propylene glycol are added to the tobacco sheet, so that the tobacco sheet has a certain viscosity. Therefore, when a smoking body containing a tobacco sheet is used in a smoking device, the heating needle or the heating sheet has a certain resistance when inserted, which will cause wear and tear to the heating needle or the heating sheet, and even break after multiple insertions and extractions.

Crushed tobacco is natural tobacco, even though it is finely crushed natural tobacco, it still maintains the texture and bulk of natural tobacco. In the manufacturing method of the present invention, shredded tobacco is added in the process of manufacturing a smoking body with a tobacco sheet as the main body, and in the process of rolling the tobacco sheet to form a columnar smoking body, the tobacco sheet itself will be bunched and gathered, forming a The state of orderly arrangement, and the shredded tobacco can occupy the space of the columnar smoking body, forming a relatively disordered state. The ordered tobacco sheet is combined with the disordered shredded tobacco, so that the smoking body forms an intermediate state between order and disorder as a whole, so as to maintain the rigidity and thermal stability of the smoking body without being too hard. And sticking makes the heating body difficult to insert. In the present invention, shredded tobacco is added before rolling, rather than filling the tobacco sheet with shredded tobacco after rolling. Refilling if rolled would destroy the structure of the rolled tobacco sheet, and since the tobacco sheet is already rolled, it will be in a very compact state. In the present invention, shredded tobacco has been placed before rolling, and the fluffy shredded tobacco can appropriately reduce the compactness of the entire smoking body during rolling, and the shredded tobacco acts as a buffer during rolling. The shredded tobacco of the present invention is placed in the middle of the second direction, and is filled inside the tobacco sheet along the first direction, so that the shredded tobacco is equivalent to extending from one end of the smoking body to the other end along the longitudinal direction of the smoking body, and It is located in the middle position along the radial direction of the smoking body. The longitudinal direction of the smoking body is, for example, the y' direction in Fig. 2 , and the radial direction of the smoking body is, for example, the x' direction in Fig. 2 . In this way, when the heating needle or the heating sheet is inserted into the smoking body, it is directly embedded in the shredded tobacco, which can obviously increase the convenience of insertion and extraction. Moreover, since the shredded tobacco is the fluffy shredded tobacco filled in the tobacco sheet along the longitudinal direction of the smoking body, it also provides an airflow channel for the inserted heating needle or heating sheet, which facilitates the circulation of the generated aerosol.

On the other hand, the pressed tobacco sheet is more compact than natural tobacco leaves and is resistant to heating, but this also causes the tobacco sheet to absorb heat slowly, and the heating is not easy to be uniform, which affects the escape of smoke, and there is no natural tobacco aroma of tobacco leaves. As natural tobacco, crushed tobacco is heated quickly and has poor heat resistance during electric heating, which will cause the amount of flue gas and nicotine to be high and low, and the released flue gas and nicotine will decrease with time. . In the present invention, shredded tobacco is added in the process of manufacturing the smoking body, the tobacco sheet wraps the shredded tobacco, and the tobacco leaves are wrapped in the middle position. Smoke and nicotine, compared with pure tobacco sheet, emit smoke faster, increase the user's experience, and experience natural tobacco flavor. In the early stage of smoking, crushed tobacco is used as the main body to release nicotine. After smoking for a period of time, the release of nicotine in shredded tobacco decreases, and at this time, the tobacco sheet has been preheated completely and begins to be the main body of nicotine release. Although the nicotine release of shredded tobacco decreases, it can still maintain Release the unique natural tobacco aroma of natural tobacco leaves. Under the user's smoking, the nicotine released by the tobacco sheet passes through an air flow channel formed in the shredded tobacco, will be mixed with the natural tobacco incense, and then enter the user's mouth. In this way, the user can not only inhale the aerosol containing the natural tobacco flavor quickly, but also obtain a continuous and stable aerosol containing the natural tobacco flavor. After the smoking test, it was found that the electric heating and smoking of natural tobacco can be maintained for less than 2 minutes at most, and the tobacco sheet of the same quality can be smoked for more than 3 minutes. The smoke body can last for more than 3 minutes to inhale the smoke containing natural tobacco incense.

To sum up, by adding shredded tobacco and setting the placement direction of the shredded tobacco, and by rolling, a columnar smoking body with both orderly arrangement and partial disorder is synthesized. In the smoking body synthesized by the manufacturing method of the present invention, the relatively disordered spaces in the interior are concentrated in the middle of the smoking body, providing a space for the insertion and extraction of the heating body and for air circulation. Through the manufacturing method of the heat-not-burn smoking body of the present invention, a smoking body that reduces the difficulty of inserting and pulling can be prepared, the service life of the heating body is prolonged, and the prepared smoking body can also realize rapid smoke emission and stable smoke. , increasing the natural smoke incense and improving the user's experience.

For the selection of the size of the shredded tobacco 4.2, it is preferable that the size of the shredded tobacco in the radial direction is 10-60 mesh, and the smaller size of the shredded tobacco is beneficial to the rolling and forming of the tobacco sheet, thus keeping the shredded tobacco above 10 mesh. If the size of the shredded tobacco is too small, it will also form a relatively tight state during rolling. In order to ensure a relatively suitable bulkiness in the shredded tobacco space, keep the shredded tobacco below 60 mesh. The shredded tobacco can be selected from shredded tobacco, shredded tobacco flakes or tobacco granules. Whether it is cut tobacco, tobacco sheet or tobacco particles, as long as the size in the radial direction of itself is 10-60 mesh. For shredded tobacco, the length is preferably less than 5 mm.

The ratio of shredded tobacco and tobacco sheet also affects the overall smoking effect of the smoking body. In order to ensure the mutual cooperation between shredded tobacco and tobacco sheet to obtain faster smoke release speed and better smoke taste, this implementation For example, the shredded tobacco 4.2 preferably accounts for 5-40 wt % of the mass of the tobacco sheet 4.1, more preferably 20-30 wt %.

In each of the above embodiments, the shredded tobacco 4.2 comes from tobacco leaf waste in the burning cigarette workshop. For a cigarette factory with an annual output of 1 million boxes, thousands of kilograms of the above-mentioned tobacco substances are screened out every day. These tobacco substances are only shredded and disposed of as garbage, and have not played their due value. In this embodiment, it is envisaged that the discarded tobacco leaf waste in the combustion type cigarette workshop is used as the shredded tobacco 4.2 in the smoking body 4 of the present invention, which can be used as waste and can play an important role in the heat-not-burning smoking body.

In each of the above examples, the shredded tobacco 4.2 is of equal size. The shredded tobacco of a relatively uniform size can be obtained by means of sieving, etc., so that the amount of smoke and the effect of smoke are more uniform. In addition, atomizers and flavors can be added to the shredded tobacco 4.2. The atomizing agent can further increase the release rate and release amount of the smoke in the shredded tobacco, for example, it can be propylene glycol, glycerol and the like. The spice can be, for example, mint, blueberry, dried tangerine peel and other flavors. In this embodiment, the selection of shredded tobacco with an equal size is more conducive to the equal distribution of the added atomizing agent and flavor, and is also conducive to obtaining a smoking body 4 that is more consistent in production. In this embodiment, it is preferred that the added amount of the atomizing agent and flavor accounts for 7%-35% of the 4.2 mass of the shredded tobacco, and the suction effect is better.

For the tobacco leaf waste from the cigarette workshop, it can also be further crushed and granulated to obtain shredded tobacco that better meets the size requirements and smoking effect. Specifically, as shown in FIG. 3 , the tobacco leaf waste in the cigarette workshop is selected and screened to obtain the smoke liquid waste of the required size, and then an atomizing agent and spices are added for charging and mixing, and dried to obtain shredded tobacco. Afterwards, the dried shredded tobacco can be directly added to the spread tobacco sheet, or the prepared shredded tobacco can also be packaged and stored, and taken out when needed.

As shown in FIG. 4 , in another embodiment, after feeding and mixing, granulation can also be performed, and tobacco leaf wastes with different shapes and sizes are made into tobacco granules. The granulation method can be, for example, a rocking method or an extrusion method. The advantage of granulation is to increase the fluidity of shredded tobacco under the condition that the tobacco material has little taste. At the same time, a screening process can be added after granulation, so that the particle size of the granules is roughly uniform, making it easier to control the amount of shredded tobacco added. . For example, it is dried after granulation, then sieved and packaged for storage. The size of the sieve is, for example, 10 to 60 meshes, and further 20 to 30 meshes.

As shown in FIG. 5 , in yet another embodiment, before the granulation, it further includes pulverizing the tobacco leaf waste. Due to the addition of the crushing link, the scope of sampling objects has been expanded, such as larger tobacco stems, tobacco flakes, shredded tobacco, and even whole tobacco leaves can be used as sampling objects. The addition of the crushing process is more conducive to the formation of granulation, which can make the granulation more regular and easier to form particles. At the same time, the expansion of the sampling range also increases the selection of materials, which is beneficial for the preparation of materials after the production scale is expanded. Specifically, after sampling the tobacco leaf waste, pulverize it first, then add an atomizing agent and spices to mix, and then perform the steps of granulation, drying, and sieving, and package and store.

In the above embodiment, the step of sieving can be divided into two times, for example, sieving can be performed before and after granulation respectively, so as to further improve the uniformity of the obtained treated tobacco leaf waste.

The shredded tobacco prepared in each of the above embodiments is used as a raw material for manufacturing a smoking body, so as to obtain a smoking body with easy insertion and extraction and improved flavor and taste.

As shown in Figures 6-8, the present invention can also adopt the manufacturing method of the heat-not-burn smoking body in the above-mentioned embodiments to obtain the smoking body 4, and then prepare a heat-not-burn cigarette with the smoking body , namely low temperature cigarette 101. The low-temperature cigarette 101 may include, for example, a filter tip 1 , an empty tube stopper 3 , and a cigarette paper wrapped around the entire periphery of the low-temperature cigarette 101 . Added a layer of wrapping paper. The empty pipe limiting member 3 has rigidity, such as PEEK with high temperature resistance, which can play a role of clamping, so that the smoking body 4 is restricted and cannot move, and can play a role in cooling.

The wrapping layer 2 directly rolls up the filter tip 1 and the smoking body 4. Since the smoking body 4 itself is wrapped by the wrapping layer 2, there is a certain binding force (or pressure, wrapping force, etc.), resulting in the smoking body. 4. The frictional force formed by the contact surface with the wrapping layer 2 is sufficient to resist the reaction force formed when the cigarette 101 is inserted into the heater, so the smoking body 4 will not move.

Although the present invention has been illustrated and described by referring to some preferred embodiments of the present invention, those of ordinary skill in the art should understand that the above content is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be assumed that Embodiments of the present invention are limited only by these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
