Description
Technical Field
The invention relates to the field of tobacco products, in particular to a preparation method of a double-layer composite hot extrusion puffing tobacco column.
Background
With the increasing of the smoking control strength and the general improvement of health consciousness of people, the heating non-combustion cigarette as an important type of novel tobacco products has great market potential, and particularly, the related preparation technology becomes a hot spot of controversial research of domestic and foreign tobacco companies. The smoke generated by the product is close to that of the traditional cigarette, but the tobacco product is controlled to be heated within the range of 300-500 ℃ by the characteristic of 'heating without combustion', and the method has the advantages that: on one hand, the smoking physiological feeling is obtained by providing the smoke when the consumer is heated and not burnt; on the other hand, the heating mode avoids a large amount of harmful components generated during high-temperature combustion, basically does not generate side-stream smoke, and does not pollute the environment.
Generally, the mode of preparing the tobacco shred raw material of the heating non-combustible tobacco product by adopting a pressurization method is common and can be roughly divided into two types: the tobacco leaf remaking by the rolling method and the tobacco shred remaking by the extrusion method are both essential auxiliary materials of cigarette leaf groups, and finally the tobacco leaf and the tobacco shred are mixed together and processed into cigarettes by a cigarette making machine. The rolling method for producing the reconstituted tobacco is a main method for producing the domestic reconstituted tobacco, namely, tobacco powder and the like are rolled into a paper form by adding an adhesive, and then the paper is cut into tobacco shreds to be used as partial raw materials of cigarettes; the patent CN105249518A discloses extruding cut tobacco, which is to extrude tobacco residue and other materials at one time by a single screw extruder, and then cut into cut tobacco shape as part of raw material of cigarette.
With the increasing production process, some tobacco materials (including tobacco fragments, auxiliary materials, etc.) are directly prepared into smokable tobacco products by a pressurization mode recently. In the patent CN104856219A, tobacco leaves are sliced after being processed, then steam is heated and moistened, and finally a certain pressure is applied to a die to press the tobacco leaves into tobacco sticks for direct smoking, so that the preparation method is convenient and efficient. Patent CN105614945A proposes mixing tobacco particles, tobacco flavor and heat conducting components, etc., pressing into cylindrical or disk-shaped tobacco column with tablet press, directly using as the smoking material of matched low-temperature cigarette smoking set, smoking speed is fast during smoking, the whole is heated uniformly and is convenient for smoking set cleaning.
