Problems solved by technology

But in this way, the contact time between the base sheet of the reconstituted tobacco leaf and the coating solution will be shortened, resulting in a reduction in the coating amount of the reconstituted tobacco leaf, which in turn will have an impact on the yield of the reconstituted tobacco leaf

Embodiment 1

[0013] Tobacco powder, tobacco stems, and shredded tobacco pieces are soaked in water as raw materials, the soluble and insoluble are extracted and separated, the insoluble tobacco fibers are beaten, and the base sheet is made by papermaking, and the soluble extract is concentrated , sprayed onto the substrate, and then prepared ammonium bicarbonate solution, and then evenly brushed the ammonium bicarbonate solution on both sides of the undried wet substrate according to 1%-10% of the absolute dry weight of the substrate. The brush-coated wet substrate was dried at 110°C until it was completely dry, and then cut to obtain the experimental sample substrate. The reconstituted tobacco leaf substrate that had not been treated with ammonium bicarbonate solution was used as a blank sample for comparison, and then according to GB / T 461.1-2002 standard was used to measure and compare the water absorption, and the comparison results are shown in Table 1.

Abstract

The invention discloses a method for improving water absorbability of reconstituted tobacco substrates. The method belongs to the technical field of reconstituted tobaccos. The method comprises the following steps of: using tobacco ends, tobacco stems and crushed tobacco flakes to serve as raw materials to be soaked by using water, conducting extraction separation on solvable objects and dissolvable objects, pulping tobacco fibers of the dissolvable objects, manufacturing into substrates through papermaking, spraying extract liquor of the solvable objects after concentration on the substrates, evenly spraying a mixed solution of one or two of carbonate and bicarbonate on positive faces and negative faces of un-stoved wet substrates according to 1%-10% of oven dry quantity of the substrates, stoving the wet substrates after spraying treatment until oven dry at the temperature of 110 DEG C, and respectively manufacturing tobacco sheets. The method is simple and practical, the water absorbability of prepared reconstituted tobacco substrates is higher than that of the reconstituted tobacco substrates prepared by using a conventional process, quality of the reconstituted tobacco substrates is not influenced, and the method is favorable for popularization and application on actual production.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco leaves, and specifically refers to a method for improving the water absorption of a base sheet of reconstituted tobacco leaves. Background technique [0002] In the prior art, reconstituted tobacco leaves are regenerated products made of tobacco materials such as tobacco powder, tobacco stems, and shredded tobacco pieces as raw materials in the form of sheets or filaments, and are used as cigarette fillers, and their physical and chemical properties are similar to those of tobacco. The preparation method of tobacco sheet mainly contains papermaking method, thick pulp method and roll pressing method at present. The typical papermaking tobacco sheet production process is to soak the raw materials in water, extract and separate the soluble matter from the insoluble matter, beat the insoluble matter tobacco fiber, make a sheet base through papermaking, and concentrate the soluble matter ...
