Problems solved by technology

[0004] The reconstituted tobacco leaves will eventually be added to cigarettes containing tobacco leaves or shredded tobacco in a certain proportion for burning. If the burning speed of cigarettes is too fast, the tobacco leaves will not burn completely, and if the burning speed is too fast, consumers will have a short smoking time and poor experience. In the prior art, the control of the burning speed of cigarettes is mostly achieved by controlling the overall burning speed of cigarettes, such as the selection of cigarette paper materials, the mixing ratio of non-combustible tobacco leaves and the types of tobacco leaves, but the burning speed of cigarette paper is lower than that of shredded tobacco. Burning speed, cigarettes will be extinguished, and the blending process involves a wide range of and complex, and this limits the utilization of diverse tobacco leaves, and the selection of cigarette flavors and tastes is reduced. Therefore, there is an urgent need for a single Method for regulating and controlling the burning speed of reconstituted tobacco leaves to control the burning speed of cigarettes

Abstract

A low-burning-velocity reconstituted tobacco leaf disclosed by the present invention comprises a composite additive component for reducing the burning velocity, and the composite additive comprises the following components: 10-90 parts of diamine hydrogen phosphate, 10-90 parts of hydrogen carbonate Sodium also provides a method for preparing reconstituted tobacco leaves with a low burning speed, which is characterized in that it includes the following steps: S1. extracting and concentrating the tobacco waste material to obtain a concentrated liquid of tobacco waste material; S2. adding compound additives to the tobacco waste material Stir and filter to obtain the filtered concentrated solution, the composite additives include diamine hydrogen phosphate and sodium bicarbonate; S3. Obtain the coating solution mixed with the filtered concentrated solution; S4. Apply the coating solution to the base The low burning speed reconstituted tobacco leaves can be obtained by drying and slicing the reconstituted tobacco leaves, which can reduce the burning speed of the reconstituted tobacco leaves and ensure complete combustion of the reconstituted tobacco leaves, with soft taste and mellow aroma.

Description

technical field [0001] The invention relates to the field of reconstituted tobacco leaves by papermaking method, in particular to a low burning speed reconstituted tobacco leaf and a preparation method thereof. Background technique [0002] Paper-making reconstituted tobacco leaves are regenerated products that use waste tobacco stems, tobacco powder, and low-grade tobacco leaves in the cigarette production process as raw materials to make sheets or filaments through the same process as papermaking. Adding it to cigarettes, on the one hand, can properly reduce the cost of cigarettes; on the other hand, it can adjust the physical properties and chemical components of cigarettes to a certain extent, and reduce the tar content, thereby helping to improve the quality of cigarettes. [0003] Its preparation process is reconstituted tobacco leaves by papermaking method, that is, using tobacco stems, tobacco powder and low-grade tobacco leaves as raw materials, after soaking and ex...
