Problems solved by technology

In this way, not only the investment is large, the production process is complicated, and the proportion of each pulp is different. When the proportion needs to be adjusted, the original beating conditions and beating strength need to be adjusted separately at the same time, so as to avoid the papermaking performance of the paper material being greatly affected.
In addition, adding the wood pulp raw material directly into the paper material after beating will have a certain impact on the suction taste of the sheet. There will be a certain burnt smell during the suction process, which will affect the suction effect, which will also affect the wood. One of the main factors for the application of pulp in sheet production and the application of sheet in cigarettes
[0006] In addition, shredded tobacco raw materials have many miscellaneous cells and low fiber content, so they are not suitable for mechanical beating, but it is difficult to find a suitable pulping process in production. Using mechanical beating, it is easy to tear the cells into small components, which seriously affects the performance of sheet making. and strength indicators

Embodiment 1

[0022] Example 1: 40% of shredded tobacco leaf raw material (tobacco leaf extract has been deducted), 42% of pretreated tobacco stem raw material, and 18% of softwood bleached pulp.

[0023] The pretreatment temperature of tobacco stem raw materials is 30°C, the ratio of solid to liquid is 1:4, and the processing time is 60 minutes. After the treatment, extrusion dehydration is adopted, and the moisture content of tobacco stem raw materials after dehydration is controlled at 55%. Add pectinase and cellulase auxiliary treatment in the pretreatment of tobacco stems. The specific dosage is: endo-cellulase: 0.01% (relative to the raw material of dry tobacco stem), pectinase: 0.25% (relative to raw material of dry tobacco stem).

[0024] According to 40% of the shredded tobacco raw material (tobacco leaf extract has been deducted: the shredded tobacco raw material is first subjected to a small pre-leaching test separately, the extract is deducted, and the amount of shredded tobacco...

Embodiment 2

[0028] Example 2: 50% of shredded tobacco raw material (tobacco leaf extract has been deducted), 30% of pretreated tobacco stem raw material, and 20% of softwood bleached pulp.

[0029] The pretreatment temperature of tobacco stem raw material is 50°C, the ratio of solid to liquid is 1:5, and the treatment time is 60 minutes. After the treatment, extrusion dehydration is adopted, and the moisture content of tobacco stem raw material after dehydration is controlled at 55%. Since the dosage of tobacco stem raw materials in this example is relatively low and the pretreatment temperature is relatively high, no enzyme pretreatment is required.

[0030] Mix the three raw materials according to the ratio of 50% of shredded tobacco leaf raw material (tobacco leaf extract has been deducted), 30% of pretreated tobacco stem raw material, and 20% of coniferous wood bleached pulp, add water to adjust the liquid ratio to 1:6, heat to 50°C, and carry out Pre-leaching. The treatment time is ...

Embodiment 3

[0035] Example 3: 35% of shredded tobacco leaf raw material (tobacco leaf extract has been deducted), 50% of pretreated tobacco stem raw material, 15% of softwood bleached pulp

[0036] The pretreatment temperature of tobacco stem raw materials is 50°C, the ratio of solid to liquid is 1:4.5, and the treatment time is 90 minutes. After the treatment, extrusion dehydration is adopted, and the moisture content of tobacco stem raw materials after dehydration is controlled at 50%. In order to improve the removal effect of bad smell in the raw material of tobacco stems during the pretreatment process, pectinase, cellulase and hemicellulase were added as auxiliary treatments in the pretreatment of tobacco stems. The specific dosage is: endo-cellulase: 0.02% (relative to the raw material of the dry tobacco stem), pectinase: 0.30% (relative to the raw material of the dry tobacco stem), and 0.015% of the hemicellulase.

[0037] According to the ratio of 35% of shredded tobacco leaf raw ...

Abstract

The invention provides a novel method for mixing and pulping raw materials in a papermaking tobacco sheet production process, which comprises the following steps of: mixing crushed tobacco, tobacco stems or stem shreds and wood pulp according to a certain ratio, extracting with hot water, dehydrating and pulping. Excessive damage to tobacco cells in the pulping process can be effectively reduced,the sheet forming effect is improved, the physical performance of sheets is improved, and meanwhile the influence of poor smoking taste caused by wood pulp raw materials can be reduced.

Description

technical field [0001] The invention belongs to the field of paper-making reconstituted tobacco leaves, and relates to beating technology, in particular to a new method for beating raw materials in the production process of paper-making reconstituted tobacco leaves. Background technique [0002] A certain amount of tobacco waste, such as shredded tobacco, shredded tobacco, and tobacco stems, will be produced during the processing of tobacco leaves and cigarettes. Shredded tobacco is mostly leftovers produced during the process of roasting, aging, and shredding of tobacco leaves, while tobacco stems are leftovers of tobacco leaves that are manually removed during tobacco leaf processing. In order to make full use of these leftovers, improve the utilization rate of tobacco raw materials, reduce the tar content of cigarettes, and improve the smoking effect of tobacco, these leftovers can be prepared into cigarette materials by recycling methods and used in the cigarette process...
