Description
Technical Field
The invention belongs to the technical field of tobacco shred manufacturing, and particularly relates to the technical field of manufacturing tobacco shreds with non-combustible cigarettes by using reconstituted tobacco leaves.
Background
The heating non-combustion cigarette is a novel cigarette which can bake the smoke substance at low temperature to generate smoke for the smokers to smoke, and can greatly reduce the generation of harmful substances due to the low temperature and the non-combustion of the tobacco shreds. The cigarette which is not burnt by heating can better adapt to the smoking ban in public places, and can meet the hobbies of tobacco consumers to a certain extent, so that the market demand is rapidly increased.
Chinese patent CN 104770852 discloses a separate cut tobacco making process suitable for paper-making reconstituted tobacco production plants, comprising the following steps: storing, shredding, feeding, temporarily storing, heating and humidifying, drying, purifying, blending and the like, and aiming at the processing characteristics of the paper-making reconstituted tobacco, the independent shredding is realized; the preparation method comprises the steps of adding materials after shredding, wherein on one hand, the materials added after shredding cannot be fused with cut tobacco, on the other hand, the materials added in the subsequent steps of warming, humidifying, drying, purifying and the like have loss, the obtained cut tobacco needs to be directly blended with other cut tobacco, and the single cut tobacco is not suitable for cigarettes which are not combusted by peripheral heating.
Chinese patent CN 102178337B discloses a separate tobacco-making process and equipment based on the processing characteristics of paper-making reconstituted tobacco, the process comprises the following process steps: opening the box, shoveling, loosening, dampening, shredding, drying and blending; the preparation method has no step of fusing the smoke agent and the tobacco in the preparation process, and is used for heating the cigarette without burning, so that the cigarette has insufficient smoke quantity and monotonous smoking taste; meanwhile, the cut tobacco obtained by the preparation method can be used only by directly blending with other cut tobacco, and even the blended cut tobacco is still not suitable for cigarettes which are not combusted by peripheral heating.
Chinese patent CN 102068036A discloses a method for improving the effective utilization rate and processing quality of reconstituted tobacco, which treats the reconstituted tobacco as a tobacco-like raw material and processes the raw material separately, wherein the reconstituted tobacco is a paper-making tobacco sheet; the paper-making method tobacco sheet is processed by a tobacco processing line independently, blended in proportion before flavoring, other procedures and parameters are kept unchanged, and finally the finished product cigarette is prepared by a packaging machine. The temperature of the cut tobacco drying procedure is higher to 90-105 ℃, when in use, the cut tobacco is mixed with other cut tobacco, and then spice is added; on one hand, the spice is poorly fused with the cut tobacco, on the other hand, the spice can be used only by being mixed with other cut tobacco and used for common cigarettes, and the spice cannot be used for cigarettes which are not combusted by peripheral heating.
Chinese patent CN 107048469 a discloses a method for manufacturing a central heating non-burning cigarette, which comprises cutting a sheet-like reconstituted tobacco into a plurality of long-strip cut tobaccos along one direction, extruding and drawing the plurality of long-strip cut tobaccos together along the width direction of the long-strip cut tobaccos, wrapping the long-strip cut tobaccos by a forming paper to form a cylindrical cigarette strip, arranging the plurality of long-strip cut tobaccos in a regular and orderly manner, and keeping the arrangement of the cut tobaccos when a heating needle is inserted, so that the smooth air circulation can be kept during smoking. The preparation method is relatively complex and has higher cost, and how the smoke agent and the tobacco are fused is not described; the obtained product is formed by extruding and drawing a plurality of long-strip cut tobaccos together along the width direction of the long-strip cut tobaccos, the obtained product is not single cut tobaccos and is used for heating the non-combustible cigarettes as a center, and the smoke quantity is not enough, so that the obtained product is not suitable for heating the non-combustible cigarettes at the periphery.
The smoking set which heats cigarettes without burning in the existing market is partially a cigarette smoking set which heats cigarettes without burning in the center and is also partially a cigarette smoking set which heats cigarettes in the periphery. The existing central heating non-combustible cigarette can not be used for peripheral heating smoking set generally. The present invention has been made to solve the above problems.
