Embodiment 1

[0019] Step (1), extraction of raw materials: Weigh the raw materials according to the ratio of wood pulp fiber: tobacco stem long stem: tobacco stem short stem: tobacco stem stem sign is 11:50:20:30, and raw material by mass ratio: water is 1 :7 add water, 70°C, extract for 45min, separate solid-liquid to obtain extract and solid, then add water according to the mass ratio of solid:water 1:5, 70°C, extract for 30min, separate solid-liquid to obtain extract and solid, solid for grinding;

[0020] Step (2), the preparation of the film base: the solid in step (1) is initially refined to a beating degree of 8°SR, and then multi-stage refining is carried out until the beating degree is 32°SR, and papermaking is carried out. Make a film base;

[0021] Step (3), concentration of the extract: Combine the extracts obtained from the two extractions in step (1), filter through a 400-mesh vibrating sieve, and concentrate to a density of 1.18g with a rotary evaporator at 70°C and a vacuu...

Embodiment 2

[0027] Step (1), extraction of raw materials: Weigh the raw materials according to the ratio of wood pulp fiber: tobacco stem long stem: tobacco stem short stem: tobacco stem stem sign is 11:40:20:40, and raw material by mass ratio: water is 1 :9 Add water, 75°C, extract for 60min, separate solid-liquid to obtain extract and solid, then add water according to the mass ratio solid:water is 1:6, add water, 75°C, extract for 45min, separate solid-liquid to obtain extract and solid, solid for grinding;

[0028] Step (2), preparation of film base: Initially refine the solid in step (1) with a degree of beating of 10°SR, and then perform multi-stage refining until the degree of beating is 35°SR, then carry out papermaking. Make a film base;

[0029] Step (3), concentration of the extract: Combine the extracts obtained from the two extractions in step (1), filter through a 400-mesh vibrating sieve, and concentrate to a density of 1.18g with a rotary evaporator at 70°C and a vacuum o...

Abstract

The invention relates to a preparation method of reconstituted tobaccos by adopting a full-stem papermaking method. The preparation method comprises the following steps: (1) extraction of raw materials; (2) preparation of a sheet base; (3) concentration of coating liquid; (4) primary alcohol precipitation treatment of a concentrated solution; (5) secondary alcohol precipitation treatment of the concentrated solution; (6) tertiary alcohol precipitation treatment of the concentrated solution; (7) coating and preparation of a sample. According to the preparation method, the quality of a stem extracting solution can be effectively improved, so that the physicochemical properties of full-stem reconstituted tobaccos are enhanced, and the quality of a product is improved; the preparation method has a high matching degree with the conventional reconstituted tobacco production process, ethyl alcohol can be completely volatilized in the subsequent process; furthermore, no other additives can be introduced, and the safety of a reconstituted tobacco product cannot be affected. The preparation method has the advantages of simple operation, low cost and high application value.

Description

technical field [0001] The invention belongs to the technical field of paper-making reconstituted tobacco leaves, and in particular relates to a method for preparing whole-stem paper-making reconstituted tobacco leaves. Background technique [0002] The main raw materials of reconstituted tobacco leaves are tobacco by-products such as tobacco stems, chips, and tobacco powder. At present, the proportion of tobacco stems in the raw material formula of domestic enterprises is about 50%-60%, and the proportion of debris (tobacco powder) is 40%-50%. At present, the supply of chips can only meet 25% of the demand for production raw materials, while there is a large surplus of raw materials for tobacco stems. Increasing the usage ratio of tobacco stems and developing high-stem (or even full-stem) reconstituted tobacco products is undoubtedly the most effective way to solve the structural contradictions of raw materials. [0003] Tobacco stems are an important part of tobacco leav...
