Description
Technical Field
The invention relates to the technical field of reconstituted tobacco, in particular to a production method of reconstituted tobacco special for heating cigarettes.
Background
The heated cigarette comprises a tobacco section, a cooling section and a filter tip section, and the most core technology is the preparation process and the raw material formula of the tobacco core material in the tobacco section. The reconstituted tobacco for mainstream heating cigarette products is widely applied by a thick pulp method and a paper making method, and in addition, the reconstituted tobacco by a rolling method and the reconstituted tobacco by a dry method are also available. The reconstituted tobacco for heating the cigarette is used as a fuming medium for bearing glycerin, nicotine and flavor components, and the reconstituted tobacco is required to be low in non-tobacco component content and rich in tobacco aroma and meet the requirements of post-processing treatment. The reconstituted tobacco by the thick paste method has high water content, long drying time in the preparation process and great loss of flavor components; the paper-making reconstituted tobacco and the dry reconstituted tobacco have poor consistency of tobacco fragrance due to large content of non-tobacco substances, heavy miscellaneous gas, lack of tobacco fragrance and the like; the reconstituted tobacco by the rolling method has low tensile strength, easy breakage and large difficulty in later processing. In the prior art, the reconstituted tobacco by the thick paste method usually needs a long time to finish drying due to high water content in the preparation process, so that the volatilization of tobacco flavor components is caused, and the retention rate of the tobacco flavor components is reduced.
Disclosure of Invention
In view of the above, the invention provides a method for producing reconstituted tobacco special for heating cigarettes, which can effectively improve the content of tobacco substances in the reconstituted tobacco by additionally adding tobacco powder on the premise of ensuring the tensile strength of the reconstituted tobacco; in addition, the second tobacco powder is applied to the coating thick paste, so that the moisture in the thick paste can be effectively absorbed, the drying time of the thick paste is shortened, and the loss rate of the fragrance in the tobacco and the additional spice is reduced.
The invention relates to a method for producing reconstituted tobacco special for heating cigarettes, which comprises the following steps:
(1) crushing: the tobacco raw material is crushed and divided into first tobacco powder and second tobacco powder, wherein the first tobacco powder is sieved by a sieve of 80-200 meshes, and the second tobacco powder is sieved by a sieve of 100-250 meshes. The tobacco material can be one or more of tobacco leaf, tobacco stem, expanded tobacco shred and expanded cut stem;
(2) grinding: the fibers are milled into a fiber slurry with a refiner. The fiber can be one or more of wood pulp, straw pulp, hemp pulp and tobacco stalk fiber;
(3) pulping: mixing the first tobacco powder, the fiber pulp obtained in the step (2), water, a binder and a smoke agent to prepare thick pulp, wherein the first tobacco powder accounts for 60-80 parts by weight, the fiber accounts for 2-10 parts by weight, the binder accounts for 1-5 parts by weight, the smoke agent accounts for 16-25 parts by weight, the water content of the thick pulp is 75-80%, the binder is one or more of edible binders such as carboxymethyl cellulose, guar gum and pectin, and the smoke agent is one or more of glycerol, propylene glycol and ethylene glycol;
(4) coating: uniformly coating the thick slurry obtained in the step (3) on a circulating metal belt to form a coating layer;
(5) spraying: and (3) spraying the second tobacco powder obtained in the step (1) on the coating layer obtained in the step (4), wherein the second tobacco powder accounts for 5-40 parts by weight. Further preferably, the second tobacco powder is 10-30 parts. The water content of the second tobacco powder is less than or equal to 7 percent; the tobacco powder is sprayed on the coating layer, so that on one hand, the content of tobacco substances is further improved on the basis of ensuring the uniform coating of the original dense slurry, and on the other hand, the tobacco powder can effectively absorb the moisture of the coating layer, so that the moisture content of the coating layer is reduced, and the drying time of the coating layer is shortened. The particle sizes of the first tobacco powder and the second tobacco powder can be the same or different, and the particle size of the second tobacco powder is smaller than that of the first tobacco powder, so that the second tobacco powder is suitable, and one main purpose of the second tobacco powder is to absorb water, and the second tobacco powder with the smaller particle size is easily loaded on the coating layer, so that the uniformity of the second tobacco powder on the coating layer is improved, and the quality of tobacco leaves is improved;
(6) primary drying: drying the material on the metal belt at 80-90 ℃ until the water content is about 20%;
(7) pressing a roller: pressing the material on the metal belt after the primary drying;
(8) stripping: stripping the material after the press roller from the metal belt to obtain a substrate;
(9) and (3) secondary drying: and (3) carrying out secondary drying on the substrate at the temperature of 40-60 ℃ until the water content of the substrate is 8-10%, thus obtaining the reconstituted tobacco for heating cigarettes.
The content of the tobacco powder in the thick slurry is limited due to the influence on the flowability of the thick slurry, so that the flowability of the thick slurry is ensured, the later-stage processing requirement of the reconstituted tobacco is met, the smoking effect of the reconstituted tobacco is met, and the content of tobacco substances in the reconstituted tobacco is limited. After the thick paste is coated, the thick paste is spread on the metal belt due to good viscosity and limited fluidity, and the dried tobacco powder is sprayed before solidification, so that the content of tobacco substances in the reconstituted tobacco can be effectively increased. In addition, the second tobacco powder is applied to the thick paste layer coated and spread on the steel belt, so that the moisture in the coating layer can be effectively absorbed, the drying time of the thick paste is shortened, and the flavor loss rate of the tobacco raw material is reduced. After the second tobacco powder is sprayed on the thick paste coating layer, a tobacco powder layer is formed on the surface of the reconstituted tobacco, so that the water absorption of glycerin in the thick paste layer can be effectively weakened, and the storage and reprocessing of the reconstituted tobacco are facilitated. The first drying time is 5-7min, and the tensile strength of the reconstituted tobacco is more than 600N/m, so that the requirement of later processing is met.
