Embodiment 1

[0023] (1) The plant fiber raw materials are divided into two groups according to long fibers and short fibers, where the ratio of long fibers to short fibers is 1:3. Then add water to the two groups of fibers and pulverize them in a hydraulic pulper. After the fiber slurry is obtained, a disc refiner is used for refining. Among them, the beating degree of long fibers is controlled at 35±2°SR, and the beating degree of short fibers is controlled at 25±2°SR.

[0024] (2) The two slurries obtained after refining in step (1) are mixed and diluted to a mass concentration of 0.3±0.05%, and then transported to a pressure screen for screening. The resulting good pulp is formed by a papermaking method, dehydrated, Drying and other processes are copied into substrates. The quantitative control of the substrate is 28±2g / m 2 , Dryness ≥80%.

Embodiment 2

[0028] (1) The plant fiber raw materials and tobacco fiber raw materials are divided into two groups according to long fibers and short fibers (tobacco fiber raw materials are regarded as short fibers), and the ratio of long fiber, short fiber and tobacco fiber raw materials is 1:1:0.5 . Then add water to the two groups of fibers and pulverize them in a hydraulic pulper. After the fiber slurry is obtained, a disc refiner is used for refining. Among them, the beating degree of long fibers is controlled at 37±2°SR, and the beating degree of short fibers is controlled at 23±2°SR.

[0029] (2) The two slurries obtained after refining in step (1) are mixed and diluted to a mass concentration of 0.4±0.05%, and then transported to a pressure screen for screening, and the resulting good pulp is formed by a papermaking method, dehydrated, Drying and other processes are copied into substrates. The quantitative control of the substrate is 32±2g / m 2 , Dryness ≥80%.

[0033] (1) Add water to the tobacco fiber material and pulverize it in a hydraulic pulper. After obtaining the fiber slurry, use a disc refiner for refining, and the beating degree is controlled at 24±2°SR.

[0034] (2) The two slurries obtained after refining in step (1) are mixed and diluted to a mass concentration of 0.5±0.05%, and then transported to a pressure screen for screening. The resulting good slurry is formed by the papermaking method, is subjected to online forming, dehydration, Drying and other processes are copied into substrates. The quantitative control of the substrate is 38±2g / m 2 , Dryness ≥80%.

[0035] (3) Spray smoke powder and glue mixture on the front surface of the substrate, and vacuum suction on the reverse side of the substrate during spraying, and set the spraying absolute dry amount to 35±2g / m 2 . Then send hot air through drying oven to dry to dryness ≥80%, set hot air temperature to 140±2℃. The components of the glue mixture are chitosan, starch-...

Abstract

The invention discloses a novel method for preparing reconstituted tobacco by virtue of a papermaking process; the method is characterized by comprising the following steps: making a substrate which is good in uniformity, high in physical strength and good in burning performance from a plant fiber raw material or a tobacco fiber raw material or plant fiber and tobacco fiber raw materials by virtue of a wet papermaking process through shaping on a net, dehydrating and drying; then directly spraying tobacco powder and glue mixture on the front and back surfaces of the substrate; and conducting such subsequent processes as drying, slicing and the like so as to obtain a finished reconstituted tobacco product; during spraying, the sprayed tobacco powder and glue mixture are adsorbed on the substrate in a mode of negative-pressure vacuum suction; and the preparation method is subject to a process of spaying, drying, re-spraying and re-drying. The preparation method disclosed by the invention has the advantages that the method not only can overcome shortcomings of non-tobacco taste and obvious offensive odor due to serious loss of smoke aroma in a reconstituted tobacco producing process by virtue of a wet papermaking method, but also can effectively avoid problems that product quality is affected and the like due to poor uniformity and strength of the substrate in a reconstituted tobacco producing process by virtue of a dry papermaking method.

Description

technical field [0001] The invention relates to a processing technology of tobacco products, in particular to a method for preparing reconstituted tobacco leaves by a novel papermaking method. Background technique [0002] Reconstituted tobacco leaves, also known as tobacco flakes or reconstituted tobacco leaves, are made of discarded tobacco stems, stem sticks, tobacco dust and some low-grade tobacco leaves and tobacco fragments in the process of cigarette manufacturing through different processing methods to make shapes close to or even superior. Reconstituted tobacco products derived from natural tobacco leaves. Reconstituted tobacco leaves have been widely used in cigarette production as a raw material for tobacco products. It has the characteristics of saving raw materials, reducing costs, improving the filling capacity and combustibility of cigarettes, and reducing the tar content in smoke. The currently known production methods of reconstituted tobacco mainly include...
