A kind of natural color bamboo pulp for reconstituted tobacco additive and preparation method thereof

Abstract

The invention belongs to the technical field of reconstituted tobacco, and specifically relates to natural-color bamboo pulp for a reconstituted tobacco additive and a preparation method thereof. The method is characterized in that bamboo is used as the raw material and subjected to preparing, stewing, squeezing extrusion, dipping, pulping and papermaking to obtain a high-purity product. The physical performance indexes of the natural-color bamboo pulp are that the tensile index is 35-45N-m / g; the burst index is 2.5-3.5kPa-m<2> / g; the tearing index is 6.5-9.5mN-m<2> / g; the intrinsic viscosity is 800-1000mL / g; the whiteness is 30-40% ISO; the pentosane is less than 8%; the ash content is less than 1.0%; the bulk is 5.0-8.5cm<3> / g. The prepared tobacco slices are added to finished cut tobacco based on ratio; the prepared cigarette is capable of supplying more air intake quantity while smoking, so that the cigarette can be promoted to completely burn, and the quantity of pyrolysis products under oxygen-poor condition can be effectively decreased, and as a result, the releasing quantity of harmful components such as tar and nicotine can be decreased.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco by a papermaking method, and particularly relates to a method for preparing natural bamboo pulp for tobacco additives by using bamboo as raw materials, in particular to a natural bamboo pulp for reconstituting tobacco additives and a preparation method thereof. Background technique [0002] Reconstituted tobacco is tobacco sheet, which is used in cigarette formulations in the form of an auxiliary material. It can reduce the consumption of tobacco leaves, reduce production costs, and effectively reduce the content of tar, nicotine, CO release and other harmful components in cigarettes. Cigarette safety, regulation of cigarette taste, etc. [0003] At present, the most widely used paper-making tobacco sheet production process in China is to use tobacco waste such as tobacco stems and tobacco chips as raw materials, extract and separate the water-soluble substances in the raw materials,...

Problems solved by technology

[0004] People in the industry believe that the best raw material for "external fiber" is bleached coniferous wood fiber, while my country's wood and hemp as "external fiber" are constrained by factors such as planting area, growth cycle, ecological balance, production cost, and environmental protection. In addition, my country's forest resources are scarce, and the country attaches great importance to ecological protection, making it difficult for the domestic supply of wood fiber raw materials to meet the raw material needs of related industries for a long time in the future. Therefore, how to develop a new type of natural and regenerated cellulose fiber suitable for my country's national conditions to make up for the shortage of raw materials and meet the market's demand for reconstituted tobacco, on the one hand, there is a new kind of new product in the field of reconstituted tobacco production. New sustainable renewable raw materials can reduce the dependence of related enterprises on imported wood pulp, save foreign exchange expenses, promote the healthy and sustainable development of the industry, and greatly reduce production costs; on the other hand, through product differentiation, not only can the enterprise Profits can also stimulate the development of related industries and form a benign interactive development of forestry pulp integration
