Embodiment 1

[0041] The defibrated coniferous wood pulp and flax pulp are mixed according to the mass ratio of 9:1, and the dry-laid film base is prepared after air-flow forming at the forming head, and the basis weight is 20g / m 2 , the bulk thickness is 6cm 3 / g. According to product design requirements and formula requirements, the coating liquid for coating is prepared. The formula of the coating liquid is: by weight, 10 parts of tobacco particles (200 mesh), 4 parts of smoking agent, 4 parts of adhesive, tobacco extract 3 parts of substance, 2 parts of dispersant, 3 parts of food additive, 2 parts of essence for tobacco, 80 parts of water, the solid content of the coating liquid is 10%, and the viscosity is 355mPa·s. According to attached figure 1 In the process flow shown, the prepared coating solution is sprayed four times (each spraying amount is 25g / m 2 ), one curtain coating (spraying amount is 30g / m 2 ) is transferred to the sheet base and the surface of the coated substrate ...

Embodiment 2

[0043] The defibrated coniferous wood pulp, tobacco stem pulp, and tobacco stem pulp were mixed according to the mass ratio of 6:1:3, and air-flow formed by the forming head to prepare a dry-laid sheet base, with a weight of 40g / m 2 , the bulk thickness is 4.8cm 3 / g. Prepare coating liquid for coating according to product design requirements and formula requirements, the formula of coating liquid is: by weight, 15 parts of tobacco particles (200 mesh), 6 parts of smoking agent, 5 parts of adhesive, tobacco extract 4 parts of substance, 2 parts of dispersant, 3 parts of food additive, 2 parts of essence for tobacco, 85 parts of water, the solid content of the coating liquid is 12%, and the viscosity is 860mPa·s. According to attached figure 2 As shown in the process flow, the prepared coating liquid is sprayed three times (each spraying amount is 25g / m 2 ), one curtain coating (spraying amount is 30g / m 2 ) to the surface and interior of the sheet base to obtain semi-finis...

Embodiment 3

[0045] The defibrated coniferous wood pulp and bamboo pulp are mixed according to the mass ratio of 7:3, and the dry-laid film base is prepared after air-flow forming at the forming head, and the basis weight is 60g / m 2 , the bulk thickness is 7cm 3 / g. Prepare coating liquid for coating according to product design requirements and formula requirements, the formula of coating liquid is: by weight, 20 parts of tobacco particles (200 mesh), 8 parts of smoking agent, 6 parts of adhesive, tobacco 5 parts of extract, 3 parts of dispersant, 4 parts of food additive, 3 parts of essence for tobacco, 90 parts of water, the solid content of the coating liquid is 13%, and the viscosity is 930mPa·s. According to attached image 3 As shown in the process flow, the prepared coating solution is sprayed twice (each spraying amount is 25g / m 2 ), two curtain coatings (each spraying amount is 30g / m 2 ) to the surface and interior of the sheet base to obtain semi-finished reconstituted tobacc...

Abstract

The invention discloses a reconstituted tobacco leaf suitable for heat-not-burn cigarettes and an improved dry method preparation method thereof, which uses dry airflow forming technology to prepare a dry method film base for coating, prepares a coating liquid, and uses spray coating combined with curtain coating The coating method is applied multiple times, and the coating solution is transferred to the film base and the surface of the coated substrate in a step-by-step multi-stage coating to obtain a semi-finished reconstituted tobacco leaf; after each coating, it is dried once, and the drying system is multi-stage dried, The soft calendering system is used for calendering finishing and drying and shaping after calendering, and the semi-finished reconstituted tobacco leaves are made into finished reconstituted tobacco leaves. The introduction of the curtain coating of the present invention and the combination of spray coating and curtain coating can better solve the problem of dry-process reconstituted tobacco quantitative, large thickness fluctuation, smoker content and coating uniformity stability Poor problems, the stability of product quality has been significantly improved.

Description

technical field [0001] The invention relates to the technical field of reconstituted tobacco leaves in the tobacco industry, and more specifically, the invention relates to a reconstituted tobacco leaf suitable for heat-not-burn cigarettes and an improved dry preparation method thereof. Background technique [0002] Heat-not-burn cigarettes are one of the important forms of new tobacco products, which mainly release endogenous and exogenous components in tobacco by heating tobacco materials at relatively low temperatures (below 300°C), thereby satisfying certain sensory needs of consumers enjoyment and physical satisfaction. Heat-not-burn cigarettes only heat the tobacco material instead of burning it, which reduces the harmful components produced by the cracking of tobacco during high-temperature combustion, and the release of sidestream smoke and environmental smoke is also significantly reduced. [0003] Reconstituted tobacco leaf is the main tobacco material used in hea...
