Problems solved by technology

[0007] In the production process of reconstituted tobacco leaves, there are reports of adding enzyme preparations to the raw materials to degrade tobacco macromolecules into small molecules to improve the smoking quality of reconstituted tobacco leaves. And there is no patent report on the method of using biological enzymes to improve the physical properties of the reconstituted tobacco paper base and applying flocculants to separate the precursors of tobacco harmful substances in the extraction line to reduce the release of harmful components when the reconstituted tobacco leaves are burned; and Adding enzyme preparations to raw materials to degrade tobacco macromolecules into small molecules will inevitably lead to the inability to separate the enzyme protein in the tobacco extract, and the enzyme protein itself will also cause a decline in the smoking quality of reconstituted tobacco leaves

Embodiment 1

[0037] Tobacco raw materials such as tobacco stems, tobacco sticks, tobacco powder, chips, and low-grade tobacco leaves are mixed in a ratio of 6:1:1:1:1, pretreated with 7 times of water at 50 degrees Celsius for 1 hour, and then the tobacco mixture and water After being squeezed by a pulper, the tobacco extract is sieved, and then enters a horizontal screw discharge sedimentation centrifuge for separation, and then enters a concentration system to concentrate to a specific gravity of 1.250.

[0038] The tobacco pulp after being squeezed by the pulper enters the pulping system, and after high, medium and low consistency refining, screening, and pulping, the beating degree of the tobacco mixed fiber is 35 0 SR, concentration 3.0%. In the process of pulping and papermaking, add wood fiber pulp equivalent to 10% of tobacco mixed fiber pulp in the pulp mixing tank, and add filler calcium carbonate equivalent to 8% of tobacco raw material pulp in the pulp forming tank. The finish...

Embodiment 2

[0041] The difference from Example 1 is that after the tobacco extract is sieved, it enters the flocculation section, the liquid flocculation addition ratio is 0.4%, the solid flocculant addition ratio is 1%, the flocculant treatment time is 20 minutes, the flocculation temperature is 35 degrees, and after flocculation Allow to settle for 20 minutes. The flocculation process module automatically controls the operation. After the flocculation treatment, the tobacco liquid is stably controlled by the flow controller, and then enters the horizontal screw discharge sedimentation centrifuge for separation.

[0042] The same amount of slag from the slag discharge outlet of the horizontal spiral unloading settling centrifuge and the tobacco extract from the discharge outlet of the horizontal screw discharge sedimentation centrifuge in Examples 1 and 2 were collected within 30 minutes, and the test data are shown in Table 1. From Table 1, the slag content of the extract of Example 2 ...

Embodiment 3

[0046] The difference from Example 1 is: when the tobacco pulp after pulping through the pulping machine enters the pulping system, add composite protease and ligninase in the tobacco pulp rough stock tank, wherein the addition ratio of composite protease is at 1.5 %, the addition ratio of ligninase is 1.0%. The slurry temperature is controlled at 30-40 degrees, the pH value is 6.0, and the reaction time is 8 hours.

[0047] The reconstituted tobacco leaf paper bases of Examples 1 and 3 were respectively taken to measure the air permeability of the base paper, and the data are shown in Table 2. It can be concluded from Table 2 that the air permeability and tensile strength of the reconstituted tobacco leaf paper base increased significantly after biological enzyme treatment.

[0050] The reconstituted tobacco leaf paper bases of Examples 1 and 3 were respectively taken to measure protein and cellulose, and the data are shown in Table 3. It can...

Abstract

The invention relates to a method of manufacturing reconstituted tobacco through a high-quality functional paper-making process. The method of manufacturing the reconstituted tobacco through the high-quality functional paper-making process is characterized by comprising the following steps: a. waste tobacco materials are extracted after being fully infiltrated in hot water, the mixture of each waste tobacco material and water enters a slurry-squeezing machine to be squeezed into slurry, and solid and liquid are separated; b. crude extract liquid enters a concentrating system and is concentrated after passing through a straight-line vibration screen and a horizontal screw decanter centrifuge, and solid-liquid separation is conducted on the crude extract liquid; c. after the slurry is squeezed through the slurry-squeezing machine, the mixture of waste tobacco materials and water enters a crude extract tobacco slurry pool, and biological enzyme processing is conducted on the tobacco slurry after compound proteases and lignin enzymes are added to the crude extract slurry pool or follow-up slurry pools. According to the method of manufacturing the reconstituted tobacco through the high-quality functional paper-making process, the content of injurious components in raw tobacco materials such as proteins, amino acids, pectins, lignin and cellulose in the reconstituted tobacco can be selectively reduced so as to reduce the number of injurious components released when the reconstituted tobacco is combusted, a large amount of zymoprotein is not left in a finished reconstituted tobacco product, and meanwhile tobacco macromolecule substances are degraded through enzymes or are separated through flocculating agents.

Description

[0001] technical field [0002] The invention belongs to the technical field of papermaking reconstituted tobacco leaves, and in particular relates to a method for manufacturing a high-quality functional reconstituted tobacco leaf product in which a flocculant is used to deeply purify and treat tobacco extract, and a biological enzyme is used to treat tobacco slurry. [0003] technical background [0004] The papermaking method of reconstituted tobacco leaves is to use tobacco stems, tobacco sticks, tobacco powder, chips, low-grade tobacco leaves and other waste materials produced during the cigarette processing process to extract tobacco soluble substances through an extraction process, and the slag is used as papermaking raw materials. base, and then the concentrated and formulated tobacco extract concentrate is coated on the paper base, dried and shredded. [0005] Paper-making method reconstituted tobacco is one of the important formulas in cigarette formula. As an eff...
