Method for reducing burning and smoking temperature of cigar

Abstract

The invention relates to the technical field of cigars, and discloses a method for reducing the burning and smoking temperature of cigars. According to the method, the water content of the cigar cigarette is controlled to be at least 15.5%, and the cigar cigarette is smoked at the time interval of (40-60) s / puff, so that the combustion cone of the cigar cigarette can be concentrated in a temperature zone below 600 DEG C during smoking. Meanwhile, in the method, due to the fact that the moisture content of the cigar cigarettes is high, the cigar cigarettes can be prevented from mildewing through the air holes formed in the cigar cigarettes; in addition, due to the arrangement of the air holes, the burning temperature of the cigar core of the cigar is more concentrated, namely, the temperature of the cigar at the radial depth of 5mm is closer to the temperature of the central point.

Description

Technical Field

[0001] The invention relates to the technical field of cigars, and in particular to a method for reducing the burning temperature of cigars. Background Art

[0002] Cigars, especially hand-rolled cigars, are a special tobacco product made from whole tobacco leaves. Compared with cigarette products, no exogenous flavors and fragrances are added. The quality of cigar tobacco leaves is affected by cigar varieties, cultivation, modulation, fermentation and other technologies. The quality of tobacco raw materials and formula blending technology determine the style and level changes of a cigar, and are ultimately reflected through the combustion process. During the smoking process of cigars, different types of tobacco leaves form complex smoke through different reactions such as distillation, pyrolysis, polymerization, and combustion. The combustion quality is crucial to the consumer experience. Smoke temperature is one of the important factors in the sensory quality of cigars, which is directly related to smoke composition, sensory quality and consumer experience.

[0003] If the burning temperature of cigars is too high, the tobacco leaves will burn too fully and the smoke will become too strong, affecting the delicacy and comfort of the taste, and increasing the spiciness, burnt smell and bitterness. It will also cause the aroma in the cigars to evaporate too quickly or change, reducing the richness and layering of the aroma, affecting the overall aroma experience. In addition, high-temperature combustion affects the smoldering, burning speed, gray and tuffiness of cigars, ultimately affecting the quality presentation and overall sensory experience of cigars. For cigars, lowering the burning temperature is of great significance for improving the quality of cigars, improving consumer experience and popularizing cigar culture.

[0004] At present, literature has found through research on cigarettes that adding potassium salts can broaden the temperature range of tobacco combustion heat release and weaken the concentration of heat release. Adding potassium salts to tobacco can help reduce the combustion temperature of cigarettes, and it is speculated that the reason is that more stable potassium-containing intermediates are produced when tobacco burns. However, the study did not show the corresponding relationship between the added potassium salt content and the smoking temperature of cigarettes. This is uncontrollable in the actual industrial application of reducing cigarette smoking, and the method of adding potassium salts is difficult to realize and transform into practical application. Summary of the invention

[0005] In order to solve the above technical problem of reducing the burning temperature of cigars, the present invention provides a method for reducing the burning temperature of cigars.

[0006] The specific technical scheme of the present invention is: The present invention provides a method for reducing the burning temperature of cigars, comprising the following steps: Step S1: controlling the suction equilibrium moisture content of the cigar to be at least 15.5%; Step S2: providing a plurality of ventilation holes on the cigar; Step S3: smoking a cigar; in: The process of smoking the cigar is performed at a time interval of (40-60) s / puff.

[0007] If the burning temperature of cigars is too high, the tobacco leaves will burn too completely and the smoke will become too strong, affecting the delicacy and comfort of the taste and increasing the spiciness, burnt smell and bitterness. Appropriately lowering the burning temperature will improve the quality of cigars.

[0008] The temperature of the cigar's combustion cone is different at different positions, with a high temperature near the center and a low temperature on the outside. During the cigar smoking process, the volume of the combustion cone decreases, accompanied by a decrease in the volume of the medium and low temperature zones (200-600°C) and an increase in the volume of the high temperature zone (>600°C); after the smoking is completed, the volume of the combustion cone expands, accompanied by a decrease in the volume of the high temperature zone and an increase in the volume of the low temperature zone. The present invention controls the moisture content of the cigar to at least 15.5%, and controls the smoking at a time interval of (40-60) s / puff, so that the combustion cone of the cigar is concentrated in the temperature zone below 600°C during smoking.

[0009] Generally, during the curing process of cigars, the moisture content of tobacco leaves will be balanced to 12.0-14.0%. In order to reduce the smoking temperature of cigars, the present invention increases the moisture content of tobacco leaves to at least 15.5%, promotes the decrease of the burning and smoking temperature, and ensures that the burning cone of cigars is concentrated in the medium and low temperature zone below 600°C by smoking at a time interval of (40-60) s / puff. If the smoking interval of cigars is too short, the continuous air circulation promotes the continuous burning of tobacco leaves, and the burning cone will continue to maintain a high temperature and a large high temperature zone volume, which will cause the cigar to be charred; if the smoking interval is too long, and the moisture content of tobacco leaves is high, the burning cone temperature of cigars will be mostly concentrated in the low temperature zone of 200-350°C, the cigars are not easy to burn, the material conversion is incomplete, the aroma permeability is reduced, and the smoking quality is reduced. Therefore, when the moisture content of tobacco leaves is increased to at least 15.5% by the method of the present invention, the smoking interval of cigars needs to be not less than 60s / puff. In the method of the present invention, since the moisture content of the cigar is relatively high, the present invention needs to set ventilation holes on the cigar to prevent mildew; in addition, due to the setting of the ventilation holes, the combustion temperature of the cigar core of the present invention is more concentrated, and the combustion temperature corresponds to the middle and high temperature zones of the combustion cone, that is, the temperatures of the middle and high temperature zones of the combustion cone are closer.

[0010] Preferably, the suction equilibrium moisture content is controlled at 15.5-17.0%.

[0011] The moisture content of cigars cannot be too high. When the moisture content exceeds 17.0%, the risk of mildew will greatly increase. At this time, the width and depth of the air holes need to be increased to a large extent. However, excessively increasing the air holes will increase the amount of air in contact with the combustion cone during inhalation, which will cause the tobacco leaves to continue burning, which is not conducive to controlling the temperature of the combustion cone below 600°C. Exceeding 600°C is not conducive to the generation of volatile components in the smoke.

[0012] Preferably, the ventilation holes penetrate the wrapper, binder and cigar core of the cigar, the diameter of the ventilation holes is 1-3 mm, and the depth of the ventilation holes is 2-5 mm.

[0013] The ventilation holes are set by drilling through them. The setting of ventilation holes can effectively reduce the risk of mildew in cigars. There are certain requirements for the penetration angle, position and hole diameter of the ventilation holes. The appropriate parameters can be set according to the length and circumference of the cigarette. It is necessary to avoid excessive loss of smoke during inhalation due to too many holes, too high density or too large diameter, which affects the inhalation experience. Controlling the diameter of several ventilation holes to 1~3mm and the depth to 2~5mm can reduce the risk of mildew while ensuring that the inhalation temperature of cigars is concentrated between 200~600℃.

[0014] Preferably, the perforation angle of the ventilation holes is 15° to 60° with respect to the axial direction of the cigar.

[0015] By making the perforation angle of the air holes form a certain angle with the axial direction of the cigar, the time for air to enter the combustion zone is slowed down, and the amount of air contacting the combustion cone during inhalation is reduced, which is conducive to controlling the temperature of the combustion cone below 600°C.

[0016] Preferably, the distance between the air holes shall not be less than 20 mm.

[0017] If the distance between the air holes is too large or there are too many air holes, the amount of air in contact with the combustion cone will increase during inhalation, which will cause the tobacco leaves to continue burning, which is not conducive to controlling the temperature of the combustion cone below 600°C.

[0018] Preferably, the distance between the ventilation hole and the smoking end of the cigar is at least 20 mm.

[0019] More preferably, the distance between the air vent which is the shortest distance from the suction end and the suction end is 20-30 mm.

[0020] If the distance between the vent and the cigar's suction end is too small, the smoke will not be concentrated, and the airflow near the mouth will spread everywhere, affecting the smoking experience. However, if the minimum distance between the vent and the suction end is too large, greater than 30mm, it will not be conducive to the vent's role in preventing mildew, and the end will have the risk of mildew.

[0021] Preferably, the distance between the ventilation hole and the ignition end of the cigar stick is at least 20 mm.

[0022] More preferably, the distance between the air hole with the shortest distance from the ignition end and the ignition end is 20-30 mm.

[0023] If the distance between the air hole and the ignition end of the cigar is too small, the initial smoke experience will be unstable, and the airflow at the ignition end will be scattered, affecting the smoking experience. However, if the minimum distance between the air hole and the ignition end is too large, greater than 30mm, it is not conducive to the air hole's role in preventing mildew, and the end is at risk of mildew.

[0024] Preferably, the process of smoking the cigar retains ash.

[0025] "Holding ash" means keeping the ash on the cigarette at a certain length when smoking, instead of flicking it off or cleaning it frequently. The purpose of holding ash during the smoking process of cigars is that, on the one hand, the ash has a certain obstructive effect on the air during the smoking process, which can reduce the air flow, slow down the air flow rate, and avoid the high temperature area of ​​the combustion cone from heating up too high and too quickly during the smoking process; on the other hand, the ash can hinder the transfer of heat and force the air flow to flow to the suction end, effectively reducing the temperature of the high temperature area of ​​the combustion cone during the smoking process and the temperature difference between it and the medium and low temperature areas, making the temperature more concentrated.

[0026] Compared with the prior art, the present invention has the following technical effects: In order to reduce the smoking temperature of cigars, the present invention increases the moisture content of tobacco leaves to at least 15.5%, promotes the decrease of the burning and smoking temperature, and ensures that the burning cone of the cigar is concentrated in the medium and low temperature area below 600°C by smoking at a time interval of (40~60) s / puff. If the smoking interval is too short during the smoking process of cigars, continuous air circulation promotes continuous burning of tobacco leaves, and the burning cone will continue to maintain a high temperature and a large high temperature area volume, which will cause the cigar to be charred; if the smoking interval is too long, coupled with the high moisture content of tobacco leaves, the burning cone temperature of cigars will be mostly concentrated in the low temperature area of ​​200~350°C, the cigars are not easy to burn, the material conversion is incomplete, the aroma permeability is reduced, and the smoking quality is reduced. Therefore, when the method of the present invention increases the moisture content of tobacco leaves to at least 15.5%, it is necessary to make the smoking interval of the cigars not less than 60s / puff. In the method of the present invention, since the moisture content of cigars is relatively high, the present invention provides a way to optimize the smoking experience, that is, to set air holes on the cigars to prevent mildew and improve the smoking quality. At the same time, due to the setting of the air holes, the combustion temperature of the cigar core of the cigar of the present invention is more concentrated, and the combustion temperature corresponds to the middle and high temperature zones of the combustion cone, that is, the temperatures of the middle and high temperature zones of the combustion cone are closer.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with embodiments. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention involved in the following description are generally only embodiments of a part of the present invention, rather than all embodiments. Therefore, based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work should belong to the scope of protection of the present invention.

[0029] Example 1 This embodiment provides a method for reducing the burning temperature of cigars, comprising the following steps: Step S1: controlling the suction equilibrium moisture content of the cigar to be at least 15.5%; Step S2: providing a plurality of ventilation holes on the cigar; Step S3: smoking a cigar; in: The process of smoking the cigar is performed at a time interval of (40-60) s / puff.

[0030] The temperature of the cigar's combustion cone is different at different positions, with a high temperature near the center and a low temperature on the outside. During the cigar smoking process, the volume of the combustion cone decreases, accompanied by a decrease in the volume of the medium and low temperature zones (200-600°C) and an increase in the volume of the high temperature zone (>600°C); after the smoking is completed, the volume of the combustion cone expands, accompanied by a decrease in the volume of the high temperature zone and an increase in the volume of the low temperature zone. In this embodiment, by controlling the moisture content of the cigar to at least 15.5% and controlling the smoking at a time interval of (40-60) s / puff, the combustion cone of the cigar can be concentrated in the temperature zone below 600°C during smoking.

[0031] Generally, during the curing process of cigars, the moisture content of tobacco leaves will be balanced to 12.0-14.0%. In order to reduce the smoking temperature of cigars, this embodiment increases the moisture content of tobacco leaves to at least 15.5%, promotes the decrease of the burning and smoking temperature, and ensures that the burning cone of cigars is concentrated in the medium and low temperature zone below 600°C by smoking at a time interval of (40-60) s / puff. If the smoking interval of cigars is too short, the continuous air circulation promotes the continuous burning of tobacco leaves, and the burning cone will continue to maintain a high temperature and a large high temperature zone volume, which will cause the cigar to be charred; if the smoking interval is too long, and the moisture content of tobacco leaves is high, the burning cone temperature of cigars will be mostly concentrated in the low temperature zone of 200-350°C, the cigars are not easy to burn, the material conversion is incomplete, the aroma permeability is reduced, and the smoking quality is reduced. Therefore, when the moisture content of tobacco leaves is increased to at least 15.5% by the method of this embodiment, the smoking interval of cigars needs to be no less than 60s / puff. In the method of this embodiment, since the moisture content of the cigar is relatively high, this embodiment needs to set ventilation holes on the cigar to prevent mildew; in addition, due to the setting of the ventilation holes, the combustion temperature of the cigar core of the cigar of this embodiment is more concentrated, and the combustion temperature corresponds to the middle and high temperature zones of the combustion cone, that is, the temperatures of the middle and high temperature zones of the combustion cone are closer.

[0032] Preferably, the suction equilibrium moisture content is controlled at 15.5-17.0%.

[0033] The moisture content of cigars cannot be too high. When the moisture content exceeds 17.0%, the risk of mildew will greatly increase. At this time, the width and depth of the air holes need to be increased to a large extent. However, excessively increasing the air holes will increase the amount of air in contact with the combustion cone during inhalation, which will cause the tobacco leaves to continue burning, which is not conducive to controlling the temperature of the combustion cone below 600°C. Exceeding 600°C is not conducive to the generation of volatile components in the smoke.

[0034] Preferably, the ventilation holes penetrate the wrapper, binder and cigar core of the cigar, the diameter of the ventilation holes is 1-3 mm, and the depth of the ventilation holes is 2-5 mm.

[0035] The main body of the cigar includes a wrapper 2, a binder and a filler 7. Figure 1 As shown in the disassembly diagram of a cigar, the cigar is rolled from a wrapper 2, a binder 3 and a filler 7. The finished cigar is as follows Figure 2 As shown, when smoking, the cigar is divided into a suction end 5 and an ignition end 6, and the suction end is the end that contacts the mouth of the smoker. The distance between the air holes 4 can be uniform or uneven, and can be set according to actual needs.

[0036] Set up ventilation holes and use mechanical methods to punch holes through them. The setting of ventilation holes can effectively reduce the risk of cigar mildew. There are certain requirements for the penetration angle, position and hole diameter of the ventilation holes. The appropriate parameters can be set according to the length and circumference of the cigarette. It is necessary to avoid excessive loss of smoke during inhalation due to too many holes, too high density or too large diameter, which affects the inhalation experience. Controlling the diameter of several ventilation holes to 1~3mm and the depth to 2~5mm can reduce the risk of mildew while ensuring that the inhalation temperature of cigars is concentrated between 200~600℃. The diameter of the ventilation holes can be understood as the maximum diameter of the hole.

[0037] Preferably, the perforation angle of the ventilation holes is 15° to 60° with respect to the axial direction of the cigar.

[0038] By making the perforation angle of the air holes form a certain angle with the axial direction of the cigar, the time for air to enter the combustion zone is slowed down, and the amount of air contacting the combustion cone during inhalation is reduced, which is conducive to controlling the temperature of the combustion cone below 600°C.

[0039] Preferably, the distance between the air holes shall not be less than 20 mm.

[0040] If the distance between the air holes is too large or there are too many air holes, the amount of air in contact with the combustion cone will increase during inhalation, which will cause the tobacco leaves to burn continuously, which is not conducive to controlling the temperature of the combustion cone below 600° C. The air holes provided in this embodiment are arranged in three groups along the axial direction of the cigar, and each group of air holes is distributed along the same radial circumference of the cigar, and the distance between each pair of air holes in each group is less than 20 mm.

[0041] Preferably, the distance between the ventilation hole and the smoking end of the cigar is at least 20 mm.

[0042] More preferably, the distance between the air vent which is the shortest distance from the suction end and the suction end is 20-30 mm.

[0043] If the distance between the vent and the cigar's suction end is too small, the smoke will not be concentrated, and the airflow near the mouth will spread everywhere, affecting the smoking experience. However, if the minimum distance between the vent and the suction end is too large, greater than 30mm, it will not be conducive to the vent's role in preventing mildew, and the end will have the risk of mildew.

[0044] Preferably, the distance between the ventilation hole and the ignition end of the cigar stick is at least 20 mm.

[0045] More preferably, the distance between the air hole with the shortest distance from the ignition end and the ignition end is 20-30 mm.

[0046] If the distance between the air hole and the ignition end of the cigar is too small, the initial smoke experience will be unstable, and the airflow at the ignition end will be scattered, affecting the smoking experience. However, if the minimum distance between the air hole and the ignition end is too large, greater than 30mm, it is not conducive to the air hole's role in preventing mildew, and the end is at risk of mildew.

[0047] Preferably, the process of smoking the cigar retains ash.

[0048] "Holding ash" means keeping the ash on the cigarette at a certain length when smoking, instead of flicking it off or cleaning it frequently. The purpose of holding ash during the smoking process of cigars is that, on the one hand, the ash has a certain obstructive effect on the air during the smoking process, which can reduce the air flow, slow down the air flow rate, and avoid the high temperature area of ​​the combustion cone from heating up too high and too quickly during the smoking process; on the other hand, the ash can hinder the transfer of heat and force the air flow to flow to the suction end, effectively reducing the temperature of the high temperature area of ​​the combustion cone during the smoking process and the temperature difference between it and the medium and low temperature areas, making the temperature more concentrated.

[0049] Compared with the prior art, the present invention has the following technical effects: In order to reduce the smoking temperature of cigars, this embodiment increases the moisture content of tobacco leaves to at least 15.5%, promotes the decrease of the burning and smoking temperature, and ensures that the burning cone of cigars is concentrated in the medium and low temperature area below 600°C by smoking at a time interval of (40~60) s / puff.

In the method of this embodiment, since the moisture content of cigars is relatively high, this embodiment provides a method for optimizing the smoking experience, that is, setting air holes on the cigars to prevent mildew and improve the smoking quality. At the same time, due to the setting of the air holes, the combustion temperature of the cigar core of the cigar of the present invention is more concentrated, and the combustion temperature corresponds to the medium and high temperature zones of the combustion cone, that is, the medium and high temperature zones of the combustion cone are closer. By burning and smoking cigars using the method provided in this embodiment, most of the volume of the combustion cone of the cigar can be concentrated in the temperature range of 350~550℃, achieving a significant cooling of the burning and smoking of the cigars and maintaining good combustibility, and the cigar has good smoking quality.

[0050] Application Example 1 Based on the method for reducing the smoking temperature of cigar provided in Example 1, this application example provides a cigar smoking method comprising the following steps: (1) The moisture content of cigars is controlled at 15.5%.

[0051] (2) A plurality of ventilation holes 4 are provided on the main body 1 of the cigar body. The arrangement method is as follows: a group of ventilation holes are provided along the axial direction of the cigar by mechanical punching. The distance between each group of ventilation holes is 25 mm. Each group of ventilation holes is distributed along the same radial circumference of the cigar. The perforation angle of the ventilation holes is 45° with the axial direction of the cigar. The distance between each two ventilation holes in each group is 23 mm. The group of ventilation holes closest to the suction end is 25 mm away from the suction end, and the group of ventilation holes closest to the ignition end is 25 mm away from the ignition end. The ventilation holes penetrate the cigar wrapper, the binder and the cigar core. The diameter of the ventilation holes is 2 mm and the depth is 3.5 mm.

[0052] (3) Use a smoking machine to smoke cigars, puffing for 2 seconds and taking 50 seconds breaks, and keep the ash during the smoking process.

[0069] Effect Characterization In the process of smoking cigars in Application Examples 1 to 6 and Comparative Examples 1 to 8, the internal temperature of the cigars was detected, specifically: using a thermocouple module to measure the temperature of the cigar burning cone, the cigar was divided into three monitoring points along the diameter direction, namely, the surface temperature, the temperature at a depth of 5 mm, and the center point temperature. During the continuous burning process from the ignition end to the suction end, the burning cone will continue to move toward the suction end, and the average temperature of the three monitoring points of the burning cone is recorded. The results are shown in Table 1. Among them, the diameter specification of the cigars in Application Examples 1 to 6 and Comparative Examples 1 to 8 is 21 mm.

[0070] Table 1 Group Surface temperature (℃) Temperature at 5mm depth (℃) Center point temperature (℃) Application Example 1 241.2 361.4 584.6 Application Example 2 239.7 367.1 581.5 Application Example 3 234.5 315.4 540.3 Application Example 4 239.4 356.7 590.4 Application Example 5 234.1 362.5 592.1 Application Example 6 236.7 360.7 589.4 Comparative Example 1 235.6 311.3 601.2 Comparative Example 2 239.7 307.1 574.6 Comparative Example 3 238.4 385.7 617.5 Comparative Example 4 237.2 331.7 581.6 Comparative Example 5 239.1 320.5 575.7 Comparative Example 6 236.7 322.4 580.3 Comparative Example 7 240.1 318.1 578.7 Comparative Example 8 239.6 357.9 607.8 From Table 1, we can see that: (1) The method of the present invention controls the moisture content of the cigar to at least 15.5% and controls the time interval of (40-60) s / puff to make the combustion cone of the cigar concentrated in the temperature range below 600°C during the puff. At the same time, in the method of the present invention, since the moisture content of the cigar is relatively high, the air holes provided on the cigar of the present invention can prevent mildew; in addition, due to the provision of the air holes, the combustion temperature of the cigar core of the present invention is more concentrated, that is, the temperature at a radial depth of 5 mm of the cigar is closer to the temperature at the center point, so that the temperature of most areas of the combustion cone of the cigar is concentrated in the temperature range of 350-600°C.

[0071] (2) The comparison between Comparative Example 1 and Application Example 1 shows the importance of moisture content control in the method of the present invention. Combined with the comparative analysis of Application Examples 2 and 3, it can be seen that the moisture content of cigars cannot be too high. When the moisture content exceeds 17.0%, the risk of mildew will be greatly increased. In order to reduce the smoking temperature of cigars, the embodiment of the present invention needs to increase the moisture content of tobacco leaves to at least 15.5%. If the moisture content of tobacco leaves is low, the combustion cone will continue to maintain a high temperature and a large high temperature zone volume during smoking; if the moisture content of tobacco leaves is high, the combustion cone temperature of cigars will be concentrated in the low temperature zone of 200~350℃, the cigars will not be easy to burn, the material conversion is incomplete, the aroma permeability is reduced, and the smoking quality is reduced.

[0072] (3) Comparative Examples 2 to 7 and Application Example 1 show the influence of the setting of the air holes and their setting methods on the burning temperature of cigar smoke. This shows that the distance between the air holes should not be less than 20 mm, the distance between the air hole with the smallest distance from the suction end and the suction end is preferably 20-30 mm, and the distance between the air hole with the smallest distance from the ignition end and the ignition end is preferably 20-30 mm.

[0073] (4) Comparative Example 8 and Application Example 1 show the effect of holding ash during smoking on the burning temperature of cigars. Holding ash during the smoking process of cigars can prevent the high temperature zone of the combustion cone from heating up too high and too quickly during the smoking process, and effectively reduce the temperature of the high temperature zone at the position of the combustion cone and the temperature difference between it and the medium and low temperature zones during the smoking process, making the temperature more concentrated.
