Description
Technical Field
The invention belongs to the technical field of reconstituted tobacco production and processing, and particularly relates to a device and a method for on-line flavoring of a spice with high and low boiling point components.
Background
Along with the acceleration of global tobacco control movement, the global tobacco industry enters a new period for seeking innovation and breakthrough, and further, the research and development of novel tobacco products mainly including heating non-burning cigarettes, electronic cigarettes, buccal cigarettes and the like are also promoted and accelerated. The heating of non-combustible cigarettes is an important component of new tobacco products.
Compared with granular and traditional tobacco shreds used as tobacco segment materials, the reconstituted tobacco sheet has the characteristics of strong plasticity, high homogenization and high adjustable level while keeping the active ingredients of natural tobacco. The reconstituted tobacco sheet is a cigarette filler which is prepared by taking tobacco waste raw materials such as tobacco stems, tobacco dust and the like as main bodies and carrying out recombination processing, and is also called a tobacco sheet. The reconstituted tobacco sheet originates from the 50 th century of the 20 th century, the development goes through 3 stages of a rolling method, a casting method and a papermaking method, and when the reconstituted tobacco sheet prepared by the casting method is formed on a sheet base, materials such as tobacco raw material powder, an adhesive, a fuming agent and the like are uniformly distributed on the surface layer and the inner layer of the sheet base, so that the reconstituted tobacco sheet is good in thickness and quantitative stability, heat conduction uniformity and fuming effect, and is one of main reasons for heating the material of the tobacco section of a non-combustible cigarette. Such as: the 'IQOS' cigarettes developed by the Feimo tobacco company are prepared into reconstituted tobacco sheets by adopting an orderly arranged casting method.
In the prior art, the process of preparing the reconstituted tobacco sheet by adopting the tape casting method is as follows: delivering the prepared reconstituted tobacco sheet slurry to a head box, controlling slurry in the head box to flow out from a slurry outlet onto a steel belt in operation through a blade door on the head box, drying the slurry on the steel belt through a heater below the steel belt, carrying out secondary flavoring through a steam pipeline before drying, scraping the reconstituted tobacco sheet by a scraper after moisture and temperature of the reconstituted tobacco sheet reach requirements, and carrying out thickness adjustment on the reconstituted tobacco sheet by a leveling device, namely a thickness adjustment roller, wherein the leveling device comprises an upper pressing roller and a lower carrier roller, and manually winding the reconstituted tobacco sheet with the same thickness onto a winding shaft.
At present, the on-line secondary flavoring is to directly spray the spice on the surface of the reconstituted tobacco slurry and close to one side of the head box, and in the process of gradually drying the reconstituted tobacco slurry into reconstituted tobacco sheets along with the operation of a steel belt, the low-boiling point and low-molecular-weight fragrant substances in the spice are dissipated along with water vapor, so that the high-boiling point fragrant substances are added into the reconstituted tobacco, and the low-boiling point and low-molecular-weight essence dissipated in the drying process is discharged into the external environment and cannot be effectively recycled, so that the environment is polluted, the using effect of the essence and the spice is reduced, the manufacturing cost is improved, and the essence raw materials are wasted.
In order to avoid the waste of raw materials, the prior art perfuming usually uses synthetic fragrances containing high boiling point fragrant substances, without selecting natural fragrances with a broad boiling point distribution and rich fragrance characteristics, such as extracts. However, the use of a single synthetic flavorant, in turn, results in a reconstituted tobacco sheet having a single flavor and flavor profile provided by only the high boiling point flavoring substances.
In addition, the surface of the reconstituted tobacco is shrunken due to the non-uniformity of heat provided by the heater in the baking and drying process of the reconstituted tobacco slurry.
The present invention has been made to solve the above problems.
