Description

Technical Field

[0001] This invention belongs to the field of heated cigarette technology, and relates to a heated cigarette made from disordered formula tobacco and its preparation method. Background Technology

[0002] In recent years, due to the implementation of the Framework Convention on Tobacco Control and increased public awareness of health and environmental protection, governments worldwide have been strengthening tobacco control measures and legislation, while market competition has intensified. Simultaneously, public calls for stronger tobacco control and anti-smoking efforts are growing stronger. Furthermore, as people's living standards continue to improve, they are paying more attention to their physical and mental health and environmental protection, and have developed a new understanding of tobacco.

[0003] Heated cigarettes are a new type of tobacco product designed based on the concept of "heating without combustion." These "relatively low-temperature cigarettes" use a heating device to heat tobacco containing smoke-generating agents to a certain temperature, allowing consumers to enjoy the aroma and nicotine and other key components, providing a pleasurable and satisfying experience. Heated cigarettes employ a "heat-not-combust" method, heating the tobacco only at a relatively low temperature (generally below 350℃), avoiding the formation of tar and harmful compounds produced by high-temperature combustion. Furthermore, they produce virtually no sideflow smoke, thus having no impact on the public environment. In recent years, many tobacco manufacturers and research institutions have focused on the field of heated cigarettes and have achieved significant results.

[0004] The balanced release of various substances in heated cigarettes is a key factor affecting the sensory evaluation of their quality. While reconstituted tobacco leaves and tobacco pellets have emerged in the market, their complex manufacturing processes and expensive equipment limit large-scale production.

[0005] Traditional tobacco processing methods still present several problems, such as harsh smoke, low smoke volume, and a strong burnt and bitter taste. These issues hinder the development of heated cigarettes made from unordered blended tobacco. Therefore, how to improve the taste and aroma of heated cigarettes made from unordered blended tobacco through technological means is a common challenge currently facing research in this field. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for preparing disordered formula tobacco heated cigarettes, which avoids the generation of tar and harmful compounds produced by high-temperature combustion, preserves the natural flavor of tobacco, improves its quality and user experience, and has low production cost and low energy consumption.

[0007] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0008] A method for preparing heated cigarettes with disordered tobacco blends includes the following steps:

[0009] Several kinds of natural tobacco leaves are mixed, and the mixed natural tobacco leaves are shredded to obtain tobacco shreds;

[0010] The tobacco shreds are dried to obtain dried tobacco shreds;

[0011] Dry tobacco shreds are subjected to a heating and moistening treatment to obtain moistened tobacco shreds;

[0012] The moistened tobacco shreds are dried to obtain re-dried tobacco shreds;

[0013] Flavoring is applied to dried tobacco shreds to produce cigarette shreds.

[0014] Tobacco shreds are subjected to constant temperature and humidity treatment to obtain finished tobacco shreds;

[0015] The finished tobacco shreds are rolled into cigarettes to produce cigarette sticks;

[0016] Pack the cigarettes.

[0017] Optionally, the moisture content of the blended natural tobacco leaves is 18.5-20.5%; the width of the tobacco shreds is 0.9-1.1 mm.

[0018] Optionally, the natural tobacco leaves include one or more combinations of flue-cured tobacco, Burley tobacco, cigar tobacco, sun-cured yellow tobacco, sun-cured red tobacco, aromatic tobacco, and Maryland tobacco.

[0019] Optionally, the tobacco shreds are dried by a high-temperature airflow, and the moisture content of the dried tobacco shreds is 9.5-10.5%.

[0020] Optionally, during the preparation of moistened tobacco, the moistening temperature is 83~89℃, the content of smoking agent in the moistened tobacco is 2~6%, the smoking agent is glycerin, and the temperature of glycerin is 100℃ when adding glycerin.

[0021] Optionally, the refried tobacco is dried using a roller, wherein the moisture content of the refried tobacco is less than 3%.

[0022] Optionally, during flavoring, the content of a smoke-generating agent in the cigarette shreds is 6-15%, the smoke-generating agent is glycerin, and the temperature of the glycerin when added is 40-60℃.

[0023] Optionally, the temperature and humidity are kept constant for at least 4 hours, with a temperature of 30~60℃ and a relative humidity of 30~40%.

[0024] Optionally, the finished tobacco shreds are rolled into cigarettes with a length of 84mm and a circumference of 17mm using a medium-sized cigarette rolling machine. The cigarettes are divided into three parts, including the tobacco shreds section, the support section, and the filter section.

[0025] The tobacco segment is 42mm long and made of pure natural tobacco shreds. The filling density of the tobacco shreds in the segment is 0.25-0.35mg / mm². 3;

[0026] The support section is 32mm long and made of hollow paper tubes. The inner diameter of the hollow part is about 4.52mm. There are two rows of through holes on the circumference of the end of the support section near the filter section. The diameter of the through holes is 0.24mm and the number of holes is 38.

[0027] The filter section is 10mm long and made of acetate fiber; the fiber bundle specification is 12.0Y / 15000d.

[0028] A type of heated cigarette made from disordered tobacco shreds is prepared by the above-described preparation method.

[0029] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0030] This invention provides a disordered formula tobacco heated cigarette and its preparation method. By using traditional tobacco equipment and a leaf group formula formed from natural tobacco leaves, a disordered formula tobacco heated cigarette production mode of "formula tobacco combination drying + low-humidity storage to remove free water + disordered rolling" is adopted. Under the condition of ensuring that the glycerol content in the smoking material is 6-15%, the dry matter content of natural tobacco leaves is increased to more than 80%.

[0031] Disordered blend tobacco heated cigarettes have advantages such as a wide range of raw material sources, no need to add new equipment, lower production costs, and less energy consumption. They can also better preserve the natural flavor of tobacco, thereby improving their quality and user experience. Attached Figure Description
