Problems solved by technology

Technicians in the industry tried to improve the cut tobacco structure by improving the shape and size of the tobacco sheet after threshing and re-baking, but failed to achieve ideal results; tried to cut the cut tobacco through fixed-length shredding, wind selection and shortening of shredded leaves, and cut tobacco cutting device Various methods such as improving the structure of shredded tobacco have achieved certain results, but they have not been widely used because of the large size of the shredded tobacco and the unsatisfactory effect of optimizing the shredded tobacco structure.

Embodiment 1

[0024] A method for optimizing the structure of shredded tobacco, comprising the following steps:

[0025] (1) Raw material moisture resurgence: the tobacco raw material is vacuum rehydrated first, and then loosened and rehydrated; the moisture content of the vacuum rehydrated material is 13.0%, and the raw material recirculation rate is 99.5%. 18.0%;

[0026] (2) Raw material feeding: According to the formula design, feed the raw materials obtained in step 1) after moisture recovery, and the moisture content of the discharged material after feeding is 18.5%;

[0027] (3) Preliminary shredding: shredding the raw materials after feeding in step 2) to obtain filamentous materials;

[0028] (4) Screening: The filamentary material obtained in step (3) is screened with a multi-stage screening machine, which is cut and cut into one device, and the tobacco powder is screened out to obtain three types of shredded tobacco. The diameter of the tobacco powder is not greater than 1.2 mm,...

Abstract

The invention discloses a method for optimizing the structure of shredded tobacco, which comprises the following steps: vacuumize the tobacco raw material first, then loosen and rehydrate; add the material according to the formula design, and obtain the silky material through preliminary shredding; and then sieve the silky material , sieve the tobacco powder and obtain three types of shredded tobacco, the diameter of the tobacco powder is not more than 1.2 mm, the diameters of the three types of shredded tobacco are respectively recorded as D1, D2 and D3, 1.2 mm<D3≤7.0 mm, 7.0 mm<D2≤13.0 mm, 13.0mm<D1; shredded tobacco with a diameter of D1 and D2 is cut, and then mixed with shredded tobacco with a diameter of D3 to obtain shredded tobacco with an optimized structure. The present invention reasonably controls moisture regain and feeding, sieves and shortens agglomerated shredded tobacco and long shreds after shredding, screens out shredded shreds, improves the uniformity of shredded tobacco structure, optimizes the shredded tobacco structure, and has remarkable draw resistance and weight stability of cigarettes Improvement, reducing the amount of short removal and saving raw material consumption.

Description

technical field [0001] The invention belongs to the technical field of cigarette production, and in particular relates to a method for optimizing the structure of shredded tobacco. Background technique [0002] Too long shredded tobacco is easy to entangle with each other to form shredded tobacco clusters, which is not conducive to uniform distribution in the shredded tobacco rod during the rolling process, and it is easy to form bamboo tobacco or empty end tobacco, which has quality defects and increases raw material consumption; the density distribution of cigarettes is also uneven, The quality stability is poor; because the shredded tobacco is entangled into a group, it is not conducive to the separation of the stems and sticks, and it is easy to pierce the cigarette, resulting in quality defects; Draw resistance, it is easy to increase the short rate and the amount of end filaments. It can be seen that the shredded tobacco can neither be too long nor too short, and shoul...
