Natural color bamboo fiber pulp, its preparation method and its application as tobacco additive

Abstract

The invention discloses an original-color bamboo fiber pulp, a preparation method thereof and an application of the bamboo fiber pulp as a tobacco additive. The original-color bamboo fiber pulp is 20-32 degree SR in a pulping degree and is 5-8g in wet weight. The preparation method includes following steps: S1: crush of raw materials: crushing bamboo fiber raw materials into fiber powder through a dry crushing method; S2: a steaming and boiling process: performing the steaming and boiling process to the fiber powder and a steaming and boiling liquid to obtain a low-hardness bamboo pulp; S3: a washing process: performing a crude selection process through a vibrating screen, a black solution extraction process through a vacuum pulp washing machine, a fine selection process through a pressure sieve, a dust removing process through a residue removing device and a pulp washing process through the vacuum pulp washing machine to obtain a screened pulp; S4: a drying process: performing a dewatering and drying process to the screened pulp to obtain an original-color bamboo fiber plate; and S5: a pulping process: performing a pulp crushing process and a pulping process to the original-color bamboo fiber plate with the pulping degree and the wet weight being controlled to prepare the original-color bamboo fiber pulp. The method is simple in operation, is convenient to carry out, is low in cost, and is green and environmental-protective. The original-color bamboo fiber pulp can be used as the tobacco additive, can reduce irritation of a tobacco sheet, can reduce bad smell of wood and the like, and can improve an original smell of tobacco.

Description

technical field

[0001] The present invention relates to a natural color bamboo fiber pulp and its preparation method and application, in particular to a natural color bamboo fiber pulp which can reduce the irritation of tobacco flakes, reduce woodiness and other bad smells, and enhance the original aroma of smoke and tobacco, and its preparation method and as a tobacco additive. Background technique

[0002] Tobacco flakes, also known as reconstituted tobacco, are made of tobacco, tobacco stems and tobacco waste (broken tobacco leaves, tobacco powder), and undergo solvent extraction (usually using water extraction, and some use alcohol extraction), separation, reorganization, and molding. Tobacco products made by techniques such as roll pressing or papermaking pulping. Among them, the paper-making reconstituted cigarette has the characteristics of low density, low tar release, and controllable chemical composition. The application of this pulp product in cigarette formula c...
