Preparation method of rolled tobacco sheet

Abstract

The invention discloses a preparation method of a rolled tobacco sheet, comprising the following steps of: a. mixing burley tobacco stems, aromatic tobacco stems and flue-cured tobacco stems to obtain mixed tobacco stems; b. mixing burley tobacco, aromatic tobacco and flue-cured tobacco powder to obtain mixed tobacco powder; c. evenly mixing cocoa powder and CMC (Carboxymethylcellulose) accordingto the proportion of 1:3-1:10 to obtain a mixed material; d. discharging the mixed tobacco stems and the mixed tobacco powder according to the proportion of 1:4-4:1 to obtain mixed powder; and e. quantitatively adding the mixed powder to a wet and dry material mixer, simultaneously adding a liquorice extract and decocting into a liquorice extract solution, squeezing, drying, cutting into shreds, drying the shreds and preparing into the tobacco sheet. The invention can effectively endow the tobacco sheet with characteristic aroma which is consistent with the style of blended type tobacco, promote the flue gas concentration and the clustering degree of the tobacco sheet, reduce the offensive taste and the irritation of the sheet, and remarkably improve the mouthfeel of the rolled sheet.

Description

Technical field: [0001] The invention relates to a method for manufacturing tobacco sheet by rolling method, in particular to a method for manufacturing tobacco sheet of middle and high-grade mixed cigarettes processed by rolling method. Background technique: [0002] Tobacco sheet, also known as reconstituted tobacco or homogeneous tobacco, is a comprehensive utilization product in tobacco industrial and agricultural production. In fact, all tobacco substances can be used in the production of tobacco sheets. The discarded tobacco stems, stem sticks, fragments, and some low-grade tobacco leaves and short stems in the entire cigarette production process are processed by different methods to make them with properties close to or even Reconstituted tobacco leaves that are superior to natural tobacco leaves. According to the different production and processing techniques of tobacco flakes, there are mainly three types of flakes: rolling method, thick pulp method and papermaking...

AI Technical Summary

Problems solved by technology

[0004] However, compared with paper-making flakes, roll-pressed flakes have disadvantages such as low filling value, poor machining resistance, low filamentation rate, large production crushing, and poor combustibility. At the same time, due to the special production process requirements, it must be used A high proportion of CMC and flake glue, and these have a relatively large negative impact on the quality of rolled flakes, mainly reflected in heavy miscellaneous gas, large irritation, and residual taste, which greatly reduces the use value of rolled flakes. It makes it difficult for roll-pressed sheets to enter the formula of middle and high-end cigarettes. Currently, they are mainly used in low-end flue-cured tobacco products.
