Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of tobacco processing, and more particularly to a method for preparing an extruded flavored cigarette cartridge. Background Art
[0002] In recent years, with growing concern about smoking and health, traditional cigarette sales have continued to decline. New tobacco products are gaining increasing attention and favor among consumers, gradually becoming a hot topic of research for tobacco researchers both domestically and internationally. Heat-not-burn (HNB) tobacco products offer advantages over traditional cigarettes, such as lower heating temperatures, lower tar content, and reduced health risks. They also offer a stylish appearance, an excellent consumer experience, and are most similar to cigarettes in terms of usage and flavor, making them particularly popular among young consumers.
[0003] Extrusion molding technology has been widely used in the food industry in recent years, offering advantages such as low process costs, diverse product forms, and high production efficiency. However, there is currently little research and application in the tobacco industry.

[0038] like Figure 1 As shown, the preparation method of the extruded flavored cigarette cartridge provided in this embodiment includes the following steps during actual implementation:
[0039] Step S1, raw material impurity removal process: including the flavor substance impurity removal process, tobacco stem impurity removal process and tobacco dust impurity removal process performed in parallel.
[0040] The raw material impurity removal process mainly removes metal impurities from the raw materials. Specifically, the raw material impurity removal process is achieved through a metal detector and a flip plate. Specifically, the metal impurities are detected by the metal detector and then picked out by the flip plate.
[0041] Furthermore, the flavoring substance includes at least one of licorice, cocoa, mint and monk fruit. It should be noted that the present invention does not specifically limit the type of flavoring substance. In other embodiments of the present invention, the flavoring substance can be other substances with unique fragrance or taste.
[0042] Step S2, raw material drying process: including the flavor substance drying process, tobacco stem drying process and tobacco dust drying process performed in parallel.
[0043] The raw material drying process is completed by a thin plate dryer. In the raw material drying process, the flavor substances, tobacco stems and tobacco dust are dried at a low temperature of ≤80°C to a moisture content of ≤10%.
[0044] Step S3, crushing process: including the flavor substance crushing process, tobacco stem crushing process and tobacco dust crushing process performed in parallel.
[0045] The pulverization process is primarily performed by a pulverizer and screening system. During the pulverization process, the tobacco stem pulverization process pulverizes the tobacco stems to a size of 55-65 mesh, for example, 60 mesh; the flavoring material pulverization process pulverizes the flavoring material to a size of 18-22 mesh, for example, 20 mesh; and the tobacco dust pulverization process pulverizes the tobacco dust to a size of 18-22 mesh, for example, 20 mesh. Specifically, during the pulverization process, the pulverized flavoring material, stem dust, or tobacco dust is screened on a sieve of corresponding size, and the materials on the sieve continue to be pulverized in the pulverizer until they are completely pulverized.
[0046] Step S4, blending and mixing process: uniformly mixing the crushed flavor substances, stem ends and tobacco ends.
[0047] Specifically, the blending process includes: the crushed flavor substances, stem ends and tobacco ends are fed into the mixing system according to a first preset ratio. Figure 2 The feed inlet of the raw material blending mixer 1 of the extrusion molding system is shown. The mass ratio of stem powder, flavoring material, and tobacco powder is (3-4):(1-2):(6-4). In a specific implementation, the stem powder and tobacco powder are added from a hopper above the raw material blending mixer 1 via a quantitative feeder.
[0048] Step S5, extrusion molding process: the mixed flavoring substances, stem and tobacco powder are mixed evenly with the adhesive and the smoke generating agent, and then extruded into a continuous tobacco rod.
[0049] The extrusion process is performed by the extrusion system, such as Figure 2 As shown, the extrusion molding system includes a raw material blending mixer 1 and a spiral mixer 2 arranged in sequence. The raw material blending mixer 1 is located on one side and above the spiral mixer 2 and is connected to the spiral mixer 2. The top of the middle part of the spiral mixer 2 is provided with an adhesive / smoking agent feeding port 3, and the side wall of the discharge end of the spiral mixer 2 is provided with an extrusion molding port 4. In one embodiment of the preparation method of the extrusion molding flavored cigarette cartridge of the present invention, the step S5 may specifically include:
[0050] Step S51: The mixed flavor substances, stem ends and tobacco ends enter the spiral mixer 2 through the discharge port located at one side of the lower end of the raw material blending mixer 1, wherein the raw material blending mixer 1 is connected to the spiral mixer 2.
[0051] Step S52 : After the adhesive and the smoke generating agent are uniformly mixed in the second ratio, the mixture is pumped into the spiral mixer 2 by the feeding pump.
[0052] The adhesive comprises at least one of low-acyl gellan gum, high-acyl gellan gum, chitin, and CMC. Exemplarily, the adhesive is a bioadhesive adhesive made from low-acyl gellan gum and high-acyl gellan gum in a mass ratio of 4:6. The smoke generator comprises a mixture of at least one of glycerol, propylene glycol, glycerol, and sorbitol with water. Exemplarily, the smoke generator comprises a mixture of glycerol and water in a mass ratio of 8:2. Specifically, the mass ratio of smoke generator to adhesive is (93-95):(7-5), for example, 94:6.
[0053] In a specific implementation, the smoke agent and adhesive are fully stirred and allowed to stand for more than 5 minutes, and then added from the adhesive / smoking agent feeding port 3 at the top of the middle part of the spiral mixer 2, and the flow rate is controlled by a mass flow meter and a gear metering pump.
[0054] Step S53: The mixture of flavoring substances, stem ends, tobacco ends, adhesive and smoke-generating agent is extruded into a continuous tobacco rod of a specified shape and size by the extrusion force of the spiral mixer 2.
[0055] The mass ratio of the mixture of flavoring substances, stem ends, and tobacco ends to the mixture of smoke-generating agents and adhesives is: (5-7): (3-5). Depending on the rolling molding system, the discharge method of the extrusion molding process includes single-hole discharge or multi-hole discharge; depending on the smoking device, the tobacco rods produced by the extrusion molding process include hollow tobacco rods or solid tobacco rods. In a specific implementation, in order to ensure smooth discharge, the molding hole of the extrusion molding system is a hollow structure, and its inner cavity is provided with 3-4 shallow grooves, and the shallow grooves are provided with feeding holes to apply a small amount of glycerin or propylene glycol to the tobacco rod.
[0056] Step S6: tobacco rod drying process.
[0057] Specifically, the rolled tobacco rods are placed on a steel belt and dried at a low temperature of ≤100°C to a moisture content of 11%-13%. The steel belt's operating speed matches the discharge speed of the extrusion process. Furthermore, the tobacco rod drying process can be performed using vacuum drying or tunnel hot air drying.
[0058] Step S7: rolling and forming process.
[0059] Specifically, the dried tobacco rods are rolled into tobacco cartridges through a rolling and forming system based on a cigarette making machine, wherein the cloth belt speed of the rolling and forming system matches the running speed of the steel belt. In the specific implementation, the rolling and forming system is modified from a cigarette making machine, specifically by removing the cigarette making machine's wire feeding and strip forming system, and directly connecting it to the steel belt in the tobacco rod drying process.
[0060] The method for preparing extruded flavored cigarette cartridges provided by the present invention enables continuous production of flavored cigarette cartridges, fully utilizing waste materials from the production process, and features a simple process flow, high production efficiency, and low production costs. The sensory quality of the cigarette cartridges is superior to that of products produced from conventional thin sheets.
