Embodiment 1

[0026] A method for preparing heat-sensitive non-burning tobacco sheets based on kraft lignin, comprising the following steps:

[0027] (1) Collect the masson pine kraft cooking waste liquor produced during the mixed cooking and pulping process of masson pine, sodium hydroxide and sodium sulfide. Acetic acid was added to masson pine kraft cooking waste liquor to adjust the pH to 4.5 to obtain kraft lignin precipitation.

[0028] (2) Put the wood pulp with a mass fraction of 20% under the action of a deflaker for 10 minutes to obtain a pulp suspension.

[0029] (3) Collect discarded tobacco stems and tobacco flakes, mix and pulverize to obtain tobacco powder.

[0030] (4) According to parts by mass, 100 parts of pulp suspension, 25 parts of smoke powder, 8 parts of mint flavor and 4 parts of kraft lignin precipitation were mixed, and the mixed suspension was obtained under the action of a decomposer for 4 minutes.

[0031] (5) Vacuum filter the mixed suspension under the cond...

Embodiment 2

[0035] A method for preparing heat-sensitive non-burning tobacco sheets based on kraft lignin, comprising the following steps:

[0036] (1) Collect the masson pine kraft cooking waste liquor produced during the mixed cooking and pulping process of masson pine, sodium hydroxide and sodium sulfide. Acetic acid was added to masson pine kraft cooking waste liquor to adjust the pH to 3.0 to obtain kraft lignin precipitation.

[0037] (2) Put the wood pulp with a mass fraction of 10% under the action of a deflaker for 5 minutes to obtain a pulp suspension.

[0038] (3) Collect discarded tobacco stems and tobacco flakes, mix and pulverize to obtain tobacco powder.

[0039] (4) According to parts by mass, mix 100 parts of pulp suspension, 20 parts of smoke powder, 5 parts of mint flavor and 3 parts of kraft lignin precipitation, and obtain a mixed suspension under the action of a decomposer for 2 minutes.

[0040] (5) Vacuum filter the mixed suspension under the condition of a vacuu...

Embodiment 3

[0044] A method for preparing heat-sensitive non-burning tobacco sheets based on kraft lignin, comprising the following steps:

[0045] (1) Collect the poplar kraft cooking waste liquor produced during the mixed cooking and pulping process of poplar chips, sodium hydroxide and sodium sulfide. Acetic acid was added to poplar kraft cooking waste liquor to adjust the pH to 7.0 to obtain kraft lignin precipitation.

[0046] (2) Put the wood pulp with a mass fraction of 30% under the action of a deflaker for 15 minutes to obtain a pulp suspension.

[0047] (3) Collect discarded tobacco stems and tobacco flakes, mix and pulverize to obtain tobacco powder.

[0048] (4) According to parts by mass, 100 parts of pulp suspension, 30 parts of smoke powder, 10 parts of lime essence and 5 parts of kraft lignin precipitation were mixed, and the mixed suspension was obtained under the action of a decomposer for 5 minutes.

[0049] (5) Vacuum filter the mixed suspension under the condition o...

Abstract

The invention relates to the technical field of heat-not-burn tobacco products, in particular to a method for preparing heat-sensitive non-burn tobacco sheets based on sulfate lignin. The method comprises the following steps: adding tobacco powder, essence and lignin into the pulp suspension, decomposing and filtering to obtain a fiber base material; hot pressing the fiber base material to obtain a non-combustible tobacco sheet. The invention adds lignin in the sheet preparation process. On the one hand, the lignin can be used as an adhesive, which reduces the use of other chemical adhesives and maintains the natural flavor of the tobacco sheet. On the other hand, the chemical bonds of lignin are broken at high temperature, causing the adhesive lignin itself and the fibrous tissue structure of the sheet to become relatively loose, so that the flavor wrapped or absorbed in it can be released, so that the flavor of the finished tobacco product is fully released when smoked , improve suction comfort.

Description

technical field [0001] The invention relates to the technical field of heat-not-burn tobacco products, in particular to a method for preparing heat-sensitive non-burn tobacco sheets based on sulfate lignin. Background technique [0002] The world cigarette market is facing the third revolution after the birth of the cigarette machine and the advent of the filter tip. As a new type of tobacco product, the new heat-not-burn cigarette is gradually becoming the product pursued by the new generation of smokers, and its market share is gradually increasing. Improvement, rapid development momentum, significant reduction in harmful chemical components and biological toxicity of smoke, and easier acceptance by younger smokers. Therefore, the research on new tobacco products and their heating devices has gradually become the key work of various tobacco industries, among which the research on tobacco products is the most important. [0003] Tobacco sheet is a product formed by process...
