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 spices with high and low boiling point components.
Background
With the acceleration of global tobacco control movement, the global tobacco industry enters a new period of seeking revolution and breakthrough, and further promotes and accelerates the research and development of novel tobacco products, such as heating non-combustion cigarettes, electronic cigarettes, buccal cigarettes and the like. The cigarette is an important component of the novel tobacco product.
Compared with granular and traditional tobacco shreds as tobacco section materials, the reconstituted tobacco sheet material has the characteristics of strong plasticity, homogenization and higher adjustable level while maintaining the active ingredients of natural tobacco. The reconstituted tobacco sheet is a cigarette filler which is prepared by using tobacco waste raw materials such as tobacco stems, tobacco powder and the like as main materials through recombination processing, and is also called as a tobacco sheet. The reconstituted tobacco sheet originates from the 50 th of the 20 th century, develops through 3 stages of a rolling method, a casting method and a paper-making method, and when the reconstituted tobacco sheet is prepared by the casting method, tobacco raw material powder, an adhesive, a smoke agent and other materials are uniformly distributed on the surface layer and the inner layer of a sheet base when the sheet base is formed, so that the reconstituted tobacco sheet has good thickness, quantitative stability, heat conduction uniformity and smoke effect, and is one of main reasons for becoming a material for heating a non-combustible cigarette tobacco section. Such as: the IQOS cigarette developed by Felmo tobacco company adopts the orderly-arranged tape-casting method to prepare the reconstituted tobacco sheet.
The process of preparing the reconstituted tobacco sheet by adopting a tape casting method in the prior art comprises the following steps: the method comprises the steps of conveying blended reconstituted tobacco sheet slurry to a flow box, controlling the slurry in the flow box to flow out of a slurry outlet to a running steel belt through a cutter on the flow box, drying the slurry on the steel belt through a heater below the steel belt, performing secondary flavoring through a steam pipeline before drying, after the reconstituted tobacco sheet is gradually formed, scraping the reconstituted tobacco sheet through a scraper after the moisture and the temperature of the reconstituted tobacco sheet meet requirements, performing thickness adjustment on the thickness of the reconstituted tobacco sheet through a flattening device, wherein the flattening device is also a thickness adjusting roller and comprises an upper compression roller and a lower support roller, and manually rolling the reconstituted tobacco sheet with the consistent thickness onto a take-up shaft.
At present, in the online secondary perfuming, the spice is directly sprayed on the surface of the reconstituted tobacco pulp and is close to one side of a flow box, and in the process of gradually drying the reconstituted tobacco pulp into a reconstituted tobacco sheet 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 fragrant substances only with the high boiling point 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 use effect of the essence and 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 generally uses synthetic perfumes containing high boiling point fragrant substances, but does not select natural perfumes with wide boiling point distribution and rich fragrance characteristics, such as the natural perfumes. . And (3) extracting. However, the use of a single synthetic spice can cause the reconstituted tobacco sheet to have single fragrance, and only has the flavor characteristics provided by high-boiling-point fragrant substances.
In addition, the surface of the reconstituted tobacco is shrunk due to the uneven heat provided by the heater in the process of baking and drying the reconstituted tobacco pulp.
The present invention has been made to solve the above problems.

5. Compared with the traditional low-boiling-point essence:
the traditional low-boiling-point essence is not separated, is added on the upper surface of the reconstituted tobacco and is discharged along with hot air flow in the drying process, so that the essence consumption is large, and in addition, the aroma-increasing effect is not obvious; the fragrance is single in character.
The low-boiling-point components are sprayed onto the steel belt 52 behind the head box in a liquid state, and as the drying process is carried out, the low-boiling-point component condensate water on the lower surface of the reconstituted tobacco pulp is heated and evaporated and enters the reconstituted tobacco pulp, so that the perfume consumption can be reduced, and the aroma-increasing effect can be improved.

the traditional high boiling point essence has single fragrance and is not rich.
The perfuming process of the essence with high and low boiling points is synchronously finished, so that the sheet material of the reconstituted tobacco has more uniform and abundant fragrance characteristics, and the labor cost is saved.
