Description
Technical Field
The invention relates to the technical field of tobacco processing, in particular to a preparation method of a tobacco sheet with high tobacco aroma and high crimpness.
Background
The tobacco sheet is also called reconstituted tobacco or homogeneous tobacco, and is a comprehensive utilization product in tobacco industrial and agricultural production. The production and application of the tobacco are developed in 50 and 60 years of the 20 th century, and the technology is characterized in that waste tobacco stems, tobacco powder and partial low-grade tobacco leaves in the whole cigarette production process (including threshing and other working procedures) are treated by different processing methods to prepare products with the properties close to or superior to those of natural tobacco leaves, and then the products are applied to cigarette production. The tobacco leaf tobacco sheet can be applied to the maximum, the production cost of the cigarette is effectively reduced, the purposes of reducing consumption and improving efficiency are achieved, and the physical properties and chemical components of the cigarette can be adjusted and improved to a certain extent by adding a proper amount of tobacco sheets into the cigarette according to the will and requirements of people, so that the internal quality of the cigarette is improved, the style and the characteristics of the cigarette are more highlighted, the harmful components in the cigarette are reduced and improved, the tar release amount of the cigarette is reduced, and the smoking safety of the cigarette is enhanced.
A cigarette which is not burnt by heating is a novel tobacco product which is rapidly developed in recent years, and the cigarette is mainly characterized in that tobacco is heated by an external heat source instead of burning the tobacco, so that substances such as flavor components in the tobacco are released. Because the tobacco products do not participate in combustion, a large amount of harmful ingredients generated by pyrolysis are avoided, the harm to human bodies is reduced while the consumers obtain satisfaction, and the environmental pollution is reduced. According to research results, the harm of the aerosol generated by heating the non-combustible cigarette is reduced by more than 90% compared with the smoke of the traditional cigarette, and the nicotine level which is basically equal to that of the cigarette can be provided. The raw material for producing the heat non-combustible tobacco may be tobacco leaf flakes. The tobacco lamina is curled during its production to adjust the burning characteristics.
The published Chinese patent with the application number of CN201510481878.6 discloses a preparation method of reconstituted tobacco sheet shreds, which comprises the following steps: a) Uniformly mixing the tobacco waste and the adhesive powder according to a mass ratio of 100-5; b) Dissolving a humectant in water according to the mass ratio of the tobacco waste to the humectant of 100-1, spraying the humectant in the tobacco powder mixture, and uniformly stirring to form a semi-moist powder mixture; c) Adding the semi-wet powder mixture into a single-screw extruder or a double-screw extruder, and performing extrusion molding through flat holes on a mouth die to obtain slender strip-shaped thin slices; d) And cutting the slender strip-shaped thin slices, and drying to obtain the required reconstituted tobacco thin slices. The preparation method is simple, has lower requirements on equipment and fields, does not generate additional production pollution, has certain crimpness and better filling property, and the tar content of the cigarette prepared by using the slice is lower. In the invention, the thin sheet threads are directly dried, so the curling degree of the tobacco thin sheets cannot be controlled, and the quality of cigarettes cannot be controlled when the cigarettes are prepared.
Chinese patent application No. cn201911118563.X discloses a method for processing a heated non-burning cigarette having a curled structure, comprising the steps of: rolling the dry and wet material mixture to obtain atomized reconstituted tobacco; dispersing a mixture of a graphene nano material, a solid adhesive and an atomizing agent in water, and uniformly spraying the mixture to one surface of the atomized reconstituted tobacco; heating and drying for the first time to obtain semi-dry heating non-combustion reconstituted tobacco; shredding to obtain semi-wet heating non-combustible reconstituted tobacco shreds; heating and drying for the second time to obtain the reconstituted tobacco shreds which are not combusted by heating; and (3) rolling and packaging to obtain the heating non-burning cigarette with the curling structure, solving the problem of adding a large proportion of atomizing agents, changing the cut tobacco from straight tobacco into natural curling, increasing the filling value, facilitating the overflow of smoke, increasing the smoke release amount, improving the smoking feeling, improving the elasticity of the cut tobacco, increasing the cohesive force, preventing the cut tobacco from falling off, improving the tensile strength of the reconstituted tobacco leaves of the heating cigarette, preventing the cut tobacco from being broken, facilitating the processing of rolling and wrapping, improving the heat conductivity and ensuring that the heating cigarette is carbonized more completely. Through the one side spraying mixture at the reconstituted tobacco in this application, through utilizing the dry shrinkage dynamics difference of reconstituted tobacco both sides to make the tobacco leaf curl, but because one side of reconstituted tobacco does not scribble anything, like this at dry in-process, the huge difference of the shrinkage dynamics of both sides, in addition the fragility of reconstituted tobacco self, the fracture of reconstituted tobacco leaf, damaged can appear in the dry curled in-process.
