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.
