Problems solved by technology

High-consistency pulping treatment of wood fibers can achieve a better splitting effect, avoiding excessive crushing and cutting of fibers, and low-consistency refining can achieve the effect of leveling and cutting; but the morphology, structure and strength of tobacco raw materials and wood fibers The difference is large. Tobacco raw materials have low fiber content, poor strength, and contain more colloids and miscellaneous cells. They cannot be divided into filaments under high-concentration refining treatment like wood fibers, but the tobacco raw materials will be excessively broken
In addition, high-consistency refining has disadvantages such as high energy consumption, unstable feed concentration, difficult control, and poor precision.
The fixed high-consistency refining method will cause excessive crushing of tobacco raw materials, resulting in poor pulp uniformity, unstable concentration and beating degree, low paper bulk, poor softness and absorbency, and low spreading rate, etc., so that tobacco poor sensory quality

Embodiment 1

[0015] A flexible and controllable tobacco pulp refining process, such as figure 1 shown, including the following steps:

[0016] (1) Medium-consistency refining: Tobacco raw materials are passed into the medium-consistency beating tank 1 after preliminary thawing and squeezing, and the mass percentage concentration is 5% detected by a densitometer, and the beating degree is 8 °SR through online detection. Slurry is sent to three medium-consistency refiners 2 connected in series, and the beating degree is detected again after medium-consistency refining, and the beating degree is 18°SR, and it is transported to the medium-consistency beating pool 3;

[0017] (2) First-level low-consistency refining: the slurry in the medium-consistency pool 3 is adjusted to a mass percentage concentration of 3% through white water, and is first-level low-consistency grinding through three first-level low-consistency refiners 4 connected in series. Slurry, after on-line detection of beating de...

Embodiment 2

[0020] A flexible and controllable tobacco pulp refining process, such as figure 2 shown, including the following steps:

[0021] (1) Medium-consistency refining: Tobacco raw materials are passed into the medium-consistency beating tank 1 after preliminary thawing and squeezing, and the mass percentage concentration is 6% as detected by the density meter, and the beating degree is 12 °SR through the online detection. Slurry is sent to two medium-consistency refiners 2 connected in series, and the beating degree is checked again after medium-consistency refining. , the on-line detection of its percussion degree is 18 ° SR, and it is transported to the medium-concentrated after-percussion pool 3;

[0022] (2) First-level low-consistency refining: the slurry in the medium-consistency pool 3 is adjusted to a mass percentage concentration of 4% by white water, and is first-level low-consistency grinding through three first-level low-consistency refiners 4 connected in series. Sl...

Embodiment 3

[0025] A flexible and controllable tobacco pulp refining process, such as image 3 shown, including the following steps:

[0026] (1) Medium-consistency refining: Tobacco raw materials are passed into the medium-consistency beating pool 1 after preliminary thawing and squeezing, and the mass percentage concentration is 10% detected by a densitometer. Transported to the medium-concentrated pool 3;

[0027] (2) First-level low-consistency refining: the slurry in the middle-consistency pool 3 is adjusted to a mass percentage concentration of 5% through white water, and is first-level low-consistency grinding through three first-level low-consistency refiners 4 connected in series. Slurry, after on-line detection of beating degree, if the beating degree is 24°SR, it will be transported to the low-concentration beating post-transition pool 5;

[0028] (3) Two-stage low-consistency refining: After low-consistency beating, the slurry in the transition tank 5 is transported to two s...

Abstract

The invention discloses a flexible and controllable tobacco pulp preparation technology. Medium consistency pulp grinding and two-stage low consistency pulp grinding are performed according to the tobacco raw material beating degree or low-consistency pulp grinding is directly performed without performing the medium consistency pulp grinding. According to the flexible and controllable tobacco pulp preparation technology, a mode of combining the medium consistency pulp grinding and the low consistency pulp grinding is adopted, advantages of the medium consistency pulp grinding and the low consistency pulp grinding are fully played, or the low consistency pulp grinding is directly performed, a most suitable pulp grinding mode is selected for tobacco raw materials in different states, and the tobacco pulp with stable concentration and beating degree is obtained.

Description

technical field [0001] The invention belongs to the field of reconstituted tobacco leaf production, in particular to a flexible and controllable tobacco pulp pulping process. Background technique [0002] Refining is the basis of papermaking reconstituted tobacco production process. At present, the refining method of reconstituted tobacco leaves in the domestic papermaking process mainly imitates the two-stage refining of the pulp and paper industry, that is, the processing method of fixed high-consistency refining and low-consistency refining. High-consistency pulping treatment of wood fibers can achieve a better splitting effect, avoiding excessive crushing and cutting of fibers, and low-consistency refining can achieve the effect of leveling and cutting; but the morphology, structure and strength of tobacco raw materials and wood fibers The difference is large. Tobacco raw materials have low fiber content, poor strength, and contain more colloids and miscellaneous cells....
