Embodiment 1

[0033] Stir and mix 100 parts of 40-80 mesh tobacco powder fragments and 3 parts of gum arabic evenly; 2 parts of propylene glycol are dissolved in 15 parts of water and sprayed into the above tobacco powder fragments containing gum arabic, and stirred to form a semi-moist powder mixture; Add the wetting material into a twin-screw extruder with a screw L / D ratio of 12, a screw lift angle of 13°, and a compression ratio of 4, and extrude it through 12 flat holes of 0.2mm*1mm on the die. Use an automatic cutting machine to cut it into short filaments with a length of 10-30mm. After microwave drying, balance the moisture content to 8% to obtain flake sample A.

Embodiment 2

[0035] Stir and mix 100 parts of tobacco powder with 60-100 mesh and 5 parts of polyethylene hot-melt adhesive powder; 3 parts of xylitol are dissolved in 20 parts of water and sprayed on the above-mentioned powdered tobacco with polyethylene hot-melt adhesive , Stir uniformly to form a semi-moist powder mixture; add the wetting material to a twin-screw extruder with a screw length-to-diameter ratio of 15, a screw lift angle of 11°, and a compression ratio of 2.5, and control the temperature in the extrusion chamber to be about 120°C The hot melt glue is melted and bonded with the powder, extruded through 10 flat holes of 0.2mm*1mm on the die, and cut into short filaments of 10-30mm length by an automatic cutting machine, and microwaved 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 dust powder, 20 parts of bagasse powder, 5 parts of starch, and 5 parts of sodium alginate; 3 parts of malto-oligosaccharide alcohol are dissolved in 20 parts of water and sprayed on the above powder containing mixture Stir uniformly to form a semi-moist powder mixture; add the wetted material to a twin-screw extruder with a screw length-to-diameter ratio of 18, a helix angle of 20°, and a compression ratio of 6 through 15 pieces of 0.15mm on the die *1.5mm flat small holes are extruded, and the automatic cutting machine is used to cut them into 10-30mm long short filaments. After microwave drying, balance the moisture content to 8% to obtain sheet 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 specifically relates to a preparation method of reconstituted tobacco flakes. Background technique [0002] Tobacco flakes are also called reconstituted tobacco, reconstituted tobacco or homogeneous tobacco. It is mainly composed of tobacco dust fragments, tobacco stems or low-grade tobacco leaves, plus plant fiber, adhesives and other additives. Reconstituted tobacco as a raw material for tobacco products has been widely used as cigarette products. The use of low-grade tobacco raw materials to prepare flakes has the characteristics of low cost, good filling properties, and can reduce tar in the smoke. The preparation methods mainly include papermaking method, thick slurry method and rolling method. Among them, the rolling method requires the use of an extruding pressure roller, and the prepared product is in the form of paper sheets, and the paper is cut into pieces. Because the p...
