Problems solved by technology

The process conditions are too severe, and the obtained slurry is too rotten, so it is impossible to produce reconstituted tobacco leaves according to the normal papermaking process
And because the cellulose content of tobacco material is relatively low, most of which are miscellaneous cellular substances that are easily hydrolyzed, after applying this production process, there are few remaining materials that can be copied, and the yield i

Embodiment 1

[0043] Put 0.04 parts of diammonium hydrogen phosphate in 6 parts of water, stir and dissolve; respectively put 0.65 parts of tobacco stems and 0.35 parts of broken tobacco pieces, and the above solution in a sealed container for 50 minutes, set the temperature at 60 °C, The pH value is 7.5; the soaked material obtained is separated into liquid phase and solid phase part by centrifugal separation equipment; the solid phase part is dissociated into a slurry with a beating degree of 30°SR by a beater, and the slurry is diluted with water to 1 The concentration of % is made into a continuous film base with a fourdrinier paper machine; the moisture content of the film base is 20%. The liquid phase part is concentrated to 1.25g / cm by vacuum evaporation equipment 3 concentration, and then coated on the base, the coated base contains 45% soluble matter (dry weight). Then it is dried in a drying cylinder to a moisture content of 12%, and the product is obtained after cutting and pack...

Embodiment 2

[0045] Example 1 was repeated with the following differences: the composition of the tobacco material was 0.7 parts tobacco stems and 0.3 parts tobacco shreds. 0.04 parts of ammonium acetate and 0.02 parts of urea, the pH value is 6. The extract is separated from the solid phase by a twin-screw extrusion device, and then the solid phase is dissociated into a slurry with a beating degree of 25°SR by a beater, and diluted with water to a concentration of 1%. Then use a fourdrinier paper machine to make a sheet base, and the moisture content of the sheet base is 25%. Extract concentrated to 1.20g / cm 3 Concentration, then coated on the film base, the coated film base contains 40% soluble matter (absolute dry weight), then dried, cut and packaged.

Embodiment 3

[0047] Repeat Example 1, with the following differences: immerse the tobacco material in a sealed tank with water at 80°C for 30 minutes, the tobacco material consists of 0.55 parts of tobacco stems, 0.30 parts of shredded tobacco flakes and 0.15 parts of tobacco dust, and 10 parts of water , 0.02 parts of ammonium carbonate to adjust the pH value to 6. The solid phase is dissociated into a slurry with a beating degree of 35°SR with a disc refiner, and the slurry is diluted with water to a concentration of 0.8%, and then made into a sheet base with a fourdrinier paper machine, and the moisture content of the sheet base is 25%. Extract concentrated to 1.25g / cm 3 concentration, and then coated on the base, the coated base contains 40% soluble matter (dry weight). It is then dried, cut and packaged.

Abstract

A technology for making the regenerated tobacco leaves by paper making method includes such steps as preparing the solution of ammonium salt or urea, filling in a container, immersing the rejected or low-grad tobacco material in it at 50-100 deg.C for 10-120 min while regulating pH=5-10, solid-liquid separation, loosening the solid phase to obtain fiber pulp, diluting, making sheet by paper-making machine, concentrating liquid phase, applying it onto said sheet, drying, and cutting.

Description

technical field [0001] The invention relates to a method for preparing reconstituted tobacco leaves, more specifically, a method for preparing reconstituted tobacco leaves by using a papermaking method. Background technique [0002] The reconstituted tobacco leaves regenerated from tobacco waste were initially used as a simple cigarette filler, but with the advancement of technology, it has gradually become an important technical means to stabilize product quality and endow cigarette products with a special style. Its use effectively reduces the release of nicotine and tar in cigarette smoke, and provides a stable source of raw materials for enterprises. [0003] At present, there are three main production processes of reconstituted tobacco leaves: thick pulp method, roll pressing method and papermaking method. Among them, the reconstituted tobacco produced by the papermaking process has the advantages of large controllable chemical composition and physical structure, super...
