Description
Technical Field
The invention relates to the technical field of cigarettes, in particular to a cigarette which is not combusted by heating and a method for manufacturing cut tobacco thereof.
Background
Along with international and domestic smoking control is becoming more and more strict, the attention of consumers to health problems is continuously promoted, the research strength of international and domestic cigarette enterprises is increased in the aspect of heating non-combustible novel tobacco, companies such as Fei Mo, English and American, Reynolds and the like successively release novel tobacco products, and a plurality of domestic cigarette enterprises also obtain achievements in the aspect of novel tobacco research and release novel tobacco products.
The novel tobacco which is not burnt by heating has the characteristic of heating tobacco shreds or tobacco extracts but not burning the tobacco shreds, a heating appliance and a cigarette bullet are needed when the novel tobacco is smoked, the tobacco shreds in the cigarette bullet are heated by a special heating source of the appliance, so that nicotine and fragrant substances in the tobacco shreds are volatilized, and smoke is generated to meet the requirements of smokers. The traditional tobacco shreds are not enough in applying amount of the atomizing agent due to insufficient absorption capacity, and generally cannot be directly used for novel tobacco, so that the heating non-combustible material used by the conventional novel tobacco product is basically reconstituted tobacco which takes tobacco components as main materials and applies a large amount of atomizing agent.
However, the reconstituted tobacco has a large difference from the traditional tobacco shreds in the aspect of physical characteristics, so that a series of problems of raw material hardening, large cigarette weight fluctuation, tobacco shred agglomeration of the reconstituted tobacco and the like in the rolling process are solved, the quality control in the cigarette process is not facilitated, and meanwhile, a large amount of adhesive needs to be applied while the atomizing agent is applied in the processing process of the reconstituted tobacco, so that certain non-tobacco smell is generated in the heating process, and the smoking quality of cigarettes which are not burnt during heating is reduced.
Disclosure of Invention
In order to solve the problems, the application provides a cigarette which is not burnt by heating and a method for manufacturing the cut tobacco, and the cut tobacco has higher content of an atomizing agent and better smoking quality after being stored stably.
The tobacco shreds obtained by the novel manufacturing method can be suitable for heating non-combustible cigarettes and can completely replace cigarettes adopting reconstituted tobacco sheets in the prior art. The inventors of the present application have surprisingly found that the rapid drying of the tobacco shreds coated with the atomizing agent by heating at a high temperature can accelerate the penetration of the atomizing agent into the tobacco shreds, i.e. have a faster absorption rate, but the high absorption rate is based on a high loss rate. The loss of the atomizing agent during drying after application of the atomizing agent is particularly high, so that a low retention in the cut tobacco leaves results. In order to improve the aerosol retention without particularly damaging the aerosol absorption rate, the inventor of the application overcomes the conventional thinking bias and reduces the heating temperature by adopting a multi-stage heating mode. Based on this, the invention of the present application has been completed.
According to a first embodiment of the present application, there is provided a method of manufacturing a tobacco shred for heat non-combustible cigarette, comprising the steps of:
(1) coating the surface of tobacco shred with atomizing agent;
(2) heating the cut tobacco leaves treated in the step (1) for the first time at 50-60 ℃, for example, the temperature is preferably 52-58 ℃, particularly preferably 56 ℃;
(3) the tobacco shreds after the primary tobacco shred drying are heated for the second time at the temperature of 80-100 ℃, for example, the temperature range is preferably 85-95 ℃, and particularly preferably 92 ℃.
The above-mentioned "atomizing agent" may employ a conventional atomizing agent such as glycerin, propylene glycol and the like. The solvent used for the atomizing agent may be water or ethanol, etc. However, the inventors of the present application have surprisingly found that the solvent of the nebulant is preferably water. Compared with the mode of using alcohol such as ethanol and the like as a solvent, on one hand, the molecular size of water is smaller than that of the alcohol solvent, on the other hand, the compatibility of pectin and fibers which are main components contained in the tobacco shreds to water is better, so that the atomizing agent using water as the solvent has higher absorption rate and higher permeability, the touch feeling of the prepared tobacco shreds is smoother, and the touch feeling stickiness of the tobacco shreds prepared by the atomizing agent using alcohol as the solvent is avoided.
Here, the mode of applying the atomizing agent is preferably spraying. As the equipment for spraying, a conventional spraying device can be used. As regards the size of the spray, it can be adjusted according to the actual rate of spraying. The spraying mode can obtain a coating mode with a milder speed, and avoids the phenomenon that the atomization absorption exceeds the saturated absorption amount due to the excessively high coating speed, so that the phenomenon of're-spitting' occurs in the drying process, namely the atomization agent in the tobacco shreds seeps outwards.
It will be readily appreciated by those skilled in the art that the coating may also be by dipping.
The time for the first heating and the second heating is preferably 0.4-0.7 min, preferably 0.5-0.6 min, and particularly preferably 0.52min, based on 1kg of tobacco shred. If the heating time exceeds the range, the continuous absorption of the atomizing agent cannot be obviously improved, and the atomizing agent cannot be obviously reduced; if the heating time is too short, the absorption of the atomizing agent is not thorough.
The tobacco shreds to be coated with the atomising agent preferably have a suitable moisture content. On the basis of the above, some conventional operations, such as the method described in patent CN102524936A, can be performed, specifically: after the tobacco leaves are loosened and moistened, the water content of the tobacco leaves is controlled to be 16-19%, the water content of the tobacco leaves is reduced by 1-3% by applying a flexible winnowing process, then the tobacco leaves are subjected to microwave drying, and the microwave frequency is set as follows: 2450 +/-50 MHz, microwave output power: 10-50 KW, drying time: 1-3 min, and the discharging temperature is 40-60 ℃.
Intermediate heating at 60-70 ℃ can be further included between the step (2) and the step (3), and the temperature of the intermediate heating is preferably 62-68 ℃, particularly preferably 65 ℃.
It is known to those skilled in the art that the heating devices involved in the first heating, the intermediate heating and the second heating are preferably multi-stage thin-plate machines common to cut-tobacco drying processes.
Before the step (1), the tobacco shreds are soaked in a soaking solution, wherein the soaking solution comprises 45-62 wt% of carboxymethyl chitosan, 0-8 wt% of a binder and the balance of a solvent according to parts by mass. The content of the carboxymethyl chitosan is preferably 50 to 60wt%, particularly preferably 55wt%, and the content of the adhesive is preferably 2 to 5wt%, particularly preferably 3 wt%.
It is understood that the "balance" is specifically calculated from 100wt% to carboxymethyl chitosan content wt% to binder content wt%.
The carboxymethyl chitosan can endow the surface of tobacco shreds with hydrophilic groups of carboxyl, has better compatibility with solute alcohol contained in the atomizing agent after the atomizing agent, promotes the alcohol to permeate into the tobacco shreds more easily, and improves the absorption rate of the carboxymethyl chitosan on the solute alcohol component contained in the atomizing agent. In addition, carboxyl contained in the carboxymethyl chitosan can partially form intermolecular hydrogen bonds with solute alcohol of the atomizing agent, and the chemical adsorption with the solute alcohol is improved. In the heating process of the step (2) and the step (3), the solute alcohol adsorbed by the carboxymethyl chitosan is not desorbed. However, in the pumping process, under the pumping heating (generally 250-300 ℃), the carboxymethyl chitosan can be desorbed.
Specific types of carboxymethyl chitosan (e.g., acetyl degree, etc.) are not particularly required, and these do not particularly impair the function of carboxymethyl chitosan.
The adhesive is used for forming a coating film on the surface of the tobacco shreds by the impregnation liquid, so that the adhesive force of the carboxymethyl chitosan on the surface of the tobacco shreds is improved. It is understood that the carboxyl group in carboxymethyl chitosan also has an affinity with the hydrophilic group of tobacco leaf thread to attach to it without the addition of a binder.
Examples of the adhesive include CMC and PVA, and other hydrophilic adhesive substances.
The solvent is C1-C4 alcohol and/or water, and the C1-C4 alcohol is methanol, ethanol or isopropanol, preferably water.
The method comprises the steps of soaking in a soaking solution such as carboxymethyl chitosan and drying, wherein the drying temperature is 20-40 ℃. The drying may be natural drying or drying.
According to a second embodiment of the present application, there is provided a heat-nonflammable cigarette having the tobacco shred obtained by the above-described production method.
According to the manufacturing method of the tobacco shreds, after the atomizing agent is coated, the first heating at 50-60 ℃ and the second heating at 80-100 ℃ are sequentially carried out. By adopting the multi-section heating and low-temperature mode, the drying is milder, the volatilization loss of the atomizing agent attached to the surface of the cut tobacco leaves before the atomizing agent is permeated into the interior is reduced, and the high content of the atomizing agent after the storage is stable is improved.
