Embodiment 1

[0033] Stir and mix 100 parts of 40-80 mesh tobacco powder fragments and 3 parts of gum arabic; dissolve 2 parts of propylene glycol in 15 parts of water and spray on the above-mentioned tobacco powder powder containing gum arabic, and stir evenly to form a semi-moist powder mixture; Put the wet material into a twin-screw extruder with a screw length-to-diameter ratio of 12, a helix angle of 13°, and a compression ratio of 4, and extrude it through 12 flat holes of 0.2mm*1mm on the die, and Cut it into short filaments with a length of 10-30mm by using an automatic cutting machine, dry them in a microwave, and then balance the moisture content to 8% to obtain a thin slice A.

Embodiment 2

[0035] Stir and mix 100 parts of 60-100 mesh tobacco powder and 5 parts of polyethylene hot-melt adhesive powder evenly; dissolve 3 parts of xylitol in 20 parts of water and spray on the above-mentioned smoke powder containing polyethylene hot-melt adhesive , stir evenly to form a semi-moist powder mixture; add the wet material into a twin-screw extruder with a screw length-to-diameter ratio of 15, a helix angle of 11°, and a compression ratio of 2.5, and control the temperature in the extrusion chamber to about 120°C Melt the hot melt adhesive and bond with the powder, extrude through 10 flat holes of 0.2mm*1mm on the die, and use an automatic cutting machine to cut it into 10-30mm long short filaments, microwave them After drying, balance the moisture content to 6% to obtain flake sample B.

Embodiment 3

[0037] Stir and mix 80 parts of 100-140 mesh tobacco powder powder, 20 parts of bagasse powder, 5 parts of starch, and 5 parts of sodium alginate; dissolve 3 parts of maltooligosaccharide alcohol in 20 parts of water and spray on the above-mentioned mixture powder In the process, stir evenly to form a semi-moist powder mixture; add the wet material into the twin-screw extruder with a screw length-to-diameter ratio of 18, a helix angle of 20°, and a compression ratio of 6, and pass through 15 0.15mm *1.5mm flat holes are extruded and cut into 10-30mm short filaments by an automatic cutting machine. After microwave drying, the moisture content is balanced to 8% to obtain thin slice C.

Abstract

The invention discloses a method for preparing reconstituted cut tobacco sheets. The method comprises the following steps that a, tobacco waste and binding agent powder are evenly mixed according to the mass ratio of 100-5:1, and a tobacco powder mixture is obtained; b, humectant is sprayed into the tobacco powder mixture after being dissolved into water according to the mass ratio of the tobacco waste to the humectant of 100:10-1, and even stirring is carried out to form a semihumid powder mixture; c, the semihumid powder mixture is added to a single-screw extruding machine or a double-screw extruding machine, and extrusion molding is carried out through a flat hole in an open die to obtain long and thin strip-shaped cut sheets; d, the long and thin strip-shaped cut sheets are cut off and dried, and the needed reconstituted cut tobacco sheets are obtained; The method for preparing the reconstituted cut tobacco sheets is simple, the requirement for equipment and places is low, and no additional production pollution is generated; meanwhile, the cut sheets have certain crimpness and good filling performance, and the tar content of cigarettes prepared from the cut sheets is lower.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a method for preparing reconstituted tobacco shreds. Background technique [0002] Tobacco flakes are also known as reconstituted tobacco leaves, reconstituted tobacco leaves or homogeneous tobacco leaves. It is mainly composed of tobacco powder fragments, tobacco stems or low-grade tobacco leaves, plus plant fibers, adhesives and other additives. Reconstituted tobacco leaves have been widely used as raw materials for cigarette products. The thin sheet prepared by using low-grade tobacco raw materials has the characteristics of low cost, good filling performance, and can reduce tar in smoke and the like. Its preparation methods mainly include papermaking method, thick pulp method and rolling method. Among them, in the rolling method, it is necessary to use an extrusion pressure roller to prepare the product in the form of a paper sheet, which is then c...
