The invention discloses a method for preparing reconstituted tobacco leaves, which belongs to the technical field of
tobacco leaf preparation. In the present invention, the
ramie fiber and
bagasse are firstly dried and crushed, soaked in
acetic acid solution, filtered and collected, mixed with
sodium hydroxide solution and heated, and then filtered to mix the
filter cake with water, added
hydrogen peroxide to disperse, and centrifuged to collect the precipitate After air-
drying, the dry product is obtained, and then
arabinose,
sorbitol, etc. are used as raw materials to prepare a
coating mixture, and then the tobacco stem and tobacco
powder are made into
powder and then extracted, and then mixed with the dried product after
steam explosion treatment, Mixing with water and
drying, and then beating and paper-making to make tobacco sheet base, and finally
coating the
coating mixture on the surface of tobacco sheet base, and placing it in a constant temperature and
humidity box before taking it out to obtain reconstituted tobacco leaves. The invention has a high
utilization rate of tobacco raw materials, and the reconstituted tobacco leaves produced have the characteristics of low
tar content and good
combustion performance. At the same time, the thickness of the tobacco leaves is uniform and the
handle is good, which meets the needs of cigarette industry production.
