Description
Technical Field
The invention relates to the technical field of heating non-combustible cigarettes, in particular to a method for treating cigarette dust of a heating cigarette.
Background
The electrically heated cigarette is a new type of tobacco product which has been gradually developed in recent years. The heated cigarette contains a large amount of smoke agents which release fragrant substances with tobacco smell after being heated, so that consumers can feel the tobacco smell without igniting the cigarette. The temperature of the heated cigarette is generally about 300 ℃, and in order to improve the satisfaction of the smoke and enable a consumer to experience similar smoking experience with the conventional cigarette, the smoke volume of the heated cigarette needs to be increased.
In the prior art, various process technologies for improving the smoke gas quantity by adding various heat conduction materials into the non-combustible cigarette to perform heat conduction modification on the non-combustible cigarette. Silicon carbide has a high thermal conductivity coefficient and is often used as a heat-conducting material for heating non-combustible cigarettes.
For example, patent document CN104382224A discloses a solid cartridge for an electronic cigarette, which mainly comprises the following components in percentage by weight: 0.1-20% of tobacco extract, 1-10% of food gum, 10-50% of humectant, 0.001-1% of preservative, 0.1-10% of heat-conducting filler, 0.1-10% of tobacco essence and perfume and 10-30% of water; the tobacco extract is one or the combination of 2 of tobacco essential oil and tobacco extract; the food gum is one or more of gelatin, sodium caseinate, acacia, sodium alginate, carrageenan, pectin, xanthan gum, beta-cyclodextrin, starch sodium phosphate, carboxymethyl starch sodium, hydroxypropyl starch, and propylene glycol alginate; the heat-conducting filler is one or a combination of more of calcium carbonate, titanium dioxide, silicon carbide and carbon powder. In the application, only the silicon carbide and the tobacco extract are mixed together on a physical layer, on one hand, the problem of uneven heat conduction caused by uneven distribution of the silicon carbide exists, on the other hand, the bonding strength between the silicon carbide and the tobacco extract is not high, and the silicon carbide is difficult to construct a stable heat conduction network for the tobacco extract.
For another example, patent document CN107319627A discloses a heated non-combustible tobacco substrate composed of silicon carbide and a method for preparing the same, which comprises: (1) adding silicon carbide powder, silicon dioxide powder, a pore-forming agent and a binder into a kneading machine according to a ratio, uniformly mixing, adding glycerol and deionized water, kneading for 60-90 minutes, and carrying out extrusion molding after vacuum pugging for 60-120 minutes; (2) after microwave drying, sintering at the temperature of 1200-1500 ℃ for 2-4 hours to obtain a silicon carbide substrate; (3) mixing the silicon carbide substrate, the tobacco extract and the essence and the spice according to a ratio, and obtaining the tobacco extract after the silicon carbide substrate is absorbed and balanced. In the application, a porous substrate is prepared by sintering silicon carbide and a pore-forming agent, and then a tobacco extract is adsorbed, the obtained product takes the silicon carbide as a main body, the tobacco fragrance is achieved only through the tobacco extract, and the tobacco fiber main body is removed, so that the tobacco fragrance is light, and the smoking taste is poorer than that of the traditional tobacco.
Disclosure of Invention
The invention aims to solve the problems and provides a treatment method for heating cigarette dust.
The technical scheme for solving the problems is to provide a method for treating heated cigarette dust, which comprises the following steps:
(1) adding tobacco powder into ethanol solution, heating and refluxing to obtain filter residue and ethanol leaching liquor;
(2) mixing the filter residue with silicon carbide and pectin, and adding into water to obtain a system a; dropwise adding a calcium chloride solution into the system a, stirring for 50-70min, and removing water to obtain modified filter residues;
(3) and (3) applying the ethanol extract to the modified filter residue, and drying to obtain the treated tobacco powder.
In the application, the step (1) is to pretreat the tobacco powder by using ethanol, so that alkaloid and flavor components in the tobacco powder are firstly retained in the ethanol, on one hand, the loss of beneficial components caused by the subsequent steps can be avoided, and on the other hand, the influence of oil-soluble components on the surface of the tobacco powder on the loading of silicon carbide in the subsequent steps can be avoided. In addition, the operation of extracting the tobacco powder by using the ethanol solution belongs to the existing common technology, and specific steps of the operation are not repeated in the application.
Then, in the step (2), firstly, pectin is dissolved in water to form a viscous body, and the filter residue containing the tobacco fibers and the silicon carbide are preliminarily bonded together through the viscous body to construct a preliminary heat conducting network. Secondly, after calcium chloride is dripped, pectin and the calcium chloride are crosslinked to form gel, so that the bonding effect is further improved, and the mechanical strength of the modified filter residue is improved. Thirdly, after adding excessive calcium chloride, calcium chloride which is not cross-linked with pectin remains in the system and is uniformly distributed among the silicon carbide under the stirring action.
On the basis, when the ethanol leaching liquor containing the ethanol is backfilled into the modified filter residue in the step (3), the ethanol can react with calcium chloride to generateCrystalline alcohol CaCl2 ·3C2H5OH, which makes calcium chloride distributed among the silicon carbide to be removed to form micropores. Part of micropores are filled with tobacco active ingredients in the ethanol leaching liquor, which is beneficial to releasing tobacco fragrant substances in a heating non-combustion state and enriching the tobacco flavor of a heating non-combustion product. Part of the micropores are not filled, so that air holes for facilitating the circulation of smoke during subsequent suction are formed, and the smoke quantity is improved.
Preferably, in step (2), water is removed by evaporation to maximize the retention of calcium chloride in the modified residue.
Preferably, the ethanol leaching liquor is applied to the modified filter residue in batches, standing is carried out for 20-30min after each application, the ethanol leaching liquor is applied again after drying, so that calcium chloride and ethanol are sufficiently reacted and separated out, and the modified filter residue sufficiently absorbs the tobacco active ingredients.
Preferably, the drying is carried out by cold air. The low temperature is favorable for producing the crystalline alcohol by combining the calcium chloride and the ethanol, and the separated crystalline alcohol can be taken away by wind power through ventilation. Of course, even if the wind cannot completely entrain the crystalline alcohol, it is irrelevant that the crystalline alcohol remains in the tobacco dust. During smoking, the temperature rise can cause the crystalline alcohol to be decomposed endothermically to regenerate calcium chloride and ethanol, but at the moment, micropores formed by calcium chloride removal are filled with tobacco active substances and smoke generated by smoking, and the micropores can not be plugged again by the calcium chloride.
Preferably, the filter residue is added into an acid solution, heated to 35-45 ℃ for reaction for 50-70min, filtered, washed until the pH value of the obtained secondary filter residue is more than 5, and then mixed with the silicon carbide and the pectin and added into water. The filter residue is firstly subjected to acid treatment, on one hand, the original and longer fiber structure of the tobacco powder can be broken, then the tobacco powder is mixed with silicon carbide, the silicon carbide and the tobacco powder short fibers are distributed at intervals, and the recombined long fibers are bonded by pectin, so that the constructed heat conduction network is uniform, and the uniformity of heat conduction is improved. On the other hand, the acid can degrade the original pectin in the tobacco powder, reduce the pectin content and avoid the influence of excessive pectin on the smoking quality of the product.
Preferably, the acid solution is hydrochloric acid solution or citric acid solution with the concentration of 0.01-0.5 mol/L.
The citric acid solution is preferably selected, so that the filter residue can be treated, lemon fragrance can be provided for the treated tobacco powder, and the smoking comfort is further improved.
Preferably, the mass ratio of the tobacco powder, the silicon carbide and the pectin is 100: (0.1-0.2): (0.1-0.2).
Preferably, the mass ratio of the tobacco powder to the calcium chloride is 100: (2-20).
Preferably, the concentration of the calcium chloride is 2-4%.
Preferably, the mass ratio of the tobacco powder to the solvent is 1: (10-20).
Preferably, the pectin is low-ester pectin.
The invention has the beneficial effects that:
1. this application is through obtaining offal and extract after with the offal ethanol treatment, then carry out chemistry pretreatment heat conduction again with the offal and modify, backfill the technique of extract again at last, neither lose the tobacco active ingredient of offal own, do not also lose under the prerequisite of the fibrous sensation of tobacco itself, effectively improved offal heat conductivility to improve the volume of giving out smoke when its follow-up heating uses.
2. This application uses the mixture of tobacco powder, carborundum, pectin and calcium chloride, forms the gel through calcium chloride and pectin crosslinking and improves the mechanical strength that the carborundum combines on the tobacco powder on the one hand, and on the other hand occupies the carborundum network through the calcium chloride to utilize the ethanol leaching liquor to take off the micropore that the calcium chloride formed, not only improves the tobacco active ingredient and backfills the joint strength to the tobacco powder, can also improve the flue gas circulation performance through the micropore, thereby improve the volume of giving out a cigarette and the fragrance of giving off a cigarette.
