Problems solved by technology

To sum up, the existing research and production of reconstituted tobacco leaves based on the thick pulp method is limited to a single focus on the adjustment of slurry composition or simple production process control, and there is no comprehensive method that can affect the quality and production process of reconstituted tobacco leaves. Such as pulp composition control, thick pulp preparation process, molding, drying, color uniformity and other aspects of comprehensive control, in order to achieve continuous production and preparation of high-strength, homogenized and good preparation of thick pulp reconstituted tobacco for heat-not-burn cigarettes

Embodiment 1

[0032] see figure 1 A method for producing high-strength homogenized tobacco material by a thick pulp papermaking method, comprising the following steps:

[0033] (1) Mix 70% water-washed tobacco stems with 30% wood fiber according to the mass ratio, and then perform enzyme treatment. The wood fibers are basswood fibers and hemp leaves, and the enzyme preparation used in the enzyme treatment is cellulase, and these raw materials can be purchased on the market. The method of enzyme treatment is as follows: the microwave expanded tobacco stem is used as the carrier of the enzyme preparation, and the microwave expanded tobacco stem loaded with cellulase is loaded into a filter bag by utilizing the characteristics of the microwave expanded tobacco stem, which has good material absorption and is not easy to decompose, and then Put the filter bag into the container where the washed tobacco stems and wood fibers are mixed, keep the filter bag at 40°C-45°C for 40 minutes, and then ta...

Embodiment 2

[0044] A method for producing high-strength homogenized tobacco material by a thick pulp papermaking method, comprising the following steps:

[0045] (1) Mix 60% washed tobacco stem with 40% red pine fiber according to the mass ratio, and then carry out enzyme treatment. The enzyme preparation used in the enzyme treatment is a mixture of hemicellulase and amylase, and these raw materials are commercially available. The method of enzyme treatment is as follows: use microwave expanded tobacco stem as the carrier of enzyme preparation, put the microwave expanded tobacco stem loaded with enzyme preparation into a filter bag, then put the filter bag into a container for mixing washed tobacco stem and wood fiber, After keeping the temperature at 50°C for 30 minutes, take out the filter bag. The expansion degree of the microwave-expanded tobacco stem used is 300-350%, and the dosage of the enzyme preparation is 0.04% of the sum of the mass of the washed tobacco stem and the red pine...

Embodiment 3

[0056] A method for producing high-strength homogenized tobacco material by a thick pulp papermaking method, comprising the following steps:

[0057] (1) Mix 80% water-washed tobacco stems with 20% hemp leaves according to the mass ratio, and then perform enzyme treatment. The enzyme preparation used in the enzyme treatment is α-L-arabinofuranosidase, and these raw materials are commercially available. The method of enzyme treatment is as follows: use microwave expanded tobacco stem as the carrier of enzyme preparation, put the microwave expanded tobacco stem loaded with enzyme preparation into a filter bag, then put the filter bag into a container for mixing washed tobacco stem and hemp leaves, After keeping the temperature at 45°C for 60 minutes, take out the filter bag. The expansion degree of the microwave-expanded tobacco stems used is 300%, and the dosage of the enzyme preparation is 0.045% of the sum of the mass of the washed tobacco stems and hemp leaves.

Abstract

The invention relates to a method for producing a high-strength homogenized tobacco material by a thick pulp papermaking method. The method comprises the following steps: washing tobacco stems with water, mixing with wood fibers, and carrying out enzyme treatment; mixing and pulping the tobacco stems and the wood fibers to obtain homogeneous mixed pulp; adding tobacco powder, a smoke agent and anadhesive into the mixed pulp, and preparing the pulp to form a tobacco base material; continuously extruding and molding the tobacco base material on a stainless steel strip, carrying out primary drying by using hot steam, and then demolding by using a scraper; vertically spraying atomized liquid on one surface, which is not the steel strip, of the molded tobacco base material after demolding, andcarrying out color homogenizing treatment; and drying for the second time by using drying equipment, removing wrinkles, and carrying out shaping and rolling. According to the invention, the tobacco raw material is subjected to refined processing, and integrated processes such as extrusion molding, graded drying, color homogenizing treatment and the like are adopted, so that the prepared tobacco material has the advantages of large atomizing agent loading capacity, high tobacco component proportion, large product smoke release amount, high release stability, good processing resistance and thelike.

Description

technical field [0001] The invention belongs to the field of preparation methods of novel heat-not-burn tobacco products. Background technique [0002] With the acceleration of the global tobacco control campaign, the tobacco industry has entered a new period of seeking change and breakthroughs, which has also promoted and accelerated the research and development of new tobacco products such as heat-not-burn cigarettes, electronic cigarettes, and snus. Heat-not-burn cigarettes are an important part of new tobacco products. [0003] At present, there are many ways to produce heat-not-burn tobacco product materials, such as dry method, rolling method, paper-making method, thick pulp method, etc. The properties of reconstituted tobacco leaf-type heat-not-burn tobacco product materials prepared by these methods are quite different. The traditional rolling method reconstituted tobacco is easy to break and has poor processing performance. In the dry process, wood pulp and other ...
