Embodiment 1

[0040] The defibrated coniferous wood pulp and flax pulp are mixed according to the mass ratio of 8:2, 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 tobacco essence, 80 parts of water, the solid content of the coating liquid is 10%, and the viscosity is 380mPa·s. figure 1 In the process flow shown, the prepared coating solution is sprayed four times (each spraying amount is 25g / m 2 ), one-time slot extrusion coating (the coating amount is 30g / m 2 ) is transferred to the sheet base and the surface of the coated substrate to obtain a ...

Embodiment 2

[0042] 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. The coating solution has a solid content of 15% and a viscosity of 850mP·s. figure 2 As shown in the process flow, the prepared coating liquid is sprayed three times (each spraying amount is 25g / m 2 ), one-time slot extrusion coating (the coating amount is 35g / m 2...

Embodiment 3

[0044] 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 extract 5 parts of substance, 3 parts of dispersant, 4 parts of food additive, 3 parts of tobacco essence, 90 parts of water; the solid content of coating liquid is 20%, the viscosity is 1370mP·s, according to the image 3 As shown in the process flow, the prepared coating liquid is sprayed twice and the amount of each spray is 30g / m 2 ), two slit extrusion coatings (35g / m 2 ) is transferred to the sheet base and the surface of the coated substrate to obtain a semi-finished reconstitut...

Abstract

The invention discloses a reconstituted tobacco leaf for heating cigarettes and its improved dry method preparation method. The dry method sheet base for coating is prepared by using the dry method air flow forming technology, and then the coating liquid is prepared, and the spray coating technology is combined with the slit extrusion method. The "spray coating-slot extrusion coating combined coating technology" formed by the pressure coating technology performs multiple multi-stage coatings to obtain semi-finished reconstituted tobacco leaves; the semi-finished reconstituted tobacco leaves pass through the drying system for multi-stage drying and soft calendering system Calendering and finishing and drying after calendering to become the finished reconstituted tobacco leaf; the improved dry-process reconstituted tobacco leaf prepared by the present invention has relatively moderate bulk, tightness, air permeability and porosity, and its physical properties have been greatly modified and improved. Improvement, suction durability and suction resistance are significantly enhanced.

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 for heating 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 heat-not-burn ciga...
