Problems solved by technology

This method effectively improves the utilization rate of expanded tobacco stems, but since the raw material used is microwave expanded tobacco stems, the cut stems obtained are in straight strips, and the size and curl degree of the cut stems are quite different from that of the cut leaves, and the cut stems and cut leaves are mixed. In addition, because the obtained cut stems are mixed only once, it is difficult to guarantee the integrity and uniformity of the cut stems formula. At the same time, it is limited by the microwave expansion technology, the operating cost is high, and the production process is relatively cumbersome, so it is difficult to produce in the field. Realization of rapid technological transformation on the basis of technology
[0006] At present, there are still the following problems in the actual production process of the filamentous shredded stem processing technology: 1. The thin-cutting and then thick-cutting process has poor adaptability to conventional tobacco stems, and the operation stability of the shredder is insufficient; 2. The multi-cutting technology of cut stems will be different. The tobacco stems of the same size are cut together, and the thinner tobacco stems are re-cut to form unusable fragments, and the effective utilization rate of the raw materials of the tobacco stems is lower; There is a large difference between curling degree and shredded leaf, and the production process is cumbersome, and the cost and difficulty of technical transformation are relatively high; 4. The classification and processing technology of tobacco stems is often based on improving the utilization rate of tobacco stem raw materials, while ignoring the production and operation costs and the completeness of tobacco stem formula sex
The existing technology often solves one problem and brings other problems at the same time. It cannot take into account the production continuity, raw material utilization rate, operating cost, cut stem size, curl degree of cut stem, and formula integrity, which limits the production of silky cut stems. Production transformation and product application of processing technology

Embodiment 1

[0025] Example 1: Preparation of high-crimp filamentous cut stems

[0026] Blending stems: the Sichuan flue-cured tobacco stems and Henan flue-cured tobacco stems produced in 2017 were evenly blended at a mass ratio of 60%:40%;

[0027] Tobacco stem screening: Screen the mixed tobacco stem raw materials, using a long-hole drum tobacco stem screening machine with a pore size of 4.5mm, and divide the tobacco stems into thin tobacco stems with a diameter of <4.5mm and thick tobacco stems with a diameter of ≥4.5mm. Tobacco stems.

[0028] Temporary storage of tobacco stems: the sieved thin tobacco stems and thick tobacco stems are stored in different temporary storage cabinets.

[0029] Thin tobacco stem processing: the temporarily stored thin tobacco stems are washed and soaked, steamed, stored, pressed, shredded, and temporarily stored. The purpose of washing and soaking stems is to increase the moisture content of the tobacco stems and remove dust on the surface of the tobacc...

Embodiment 2

[0033] Example 2: Preparation of high-crimp shredded stems

[0034] Blending stems: The Sichuan flue-cured tobacco stems and Yunnan flue-cured tobacco stems produced in 2017 were evenly blended at a mass ratio of 30%:70%.

[0035] Tobacco stem screening: Screen the mixed tobacco stem raw materials, using a long-hole drum tobacco stem screening machine with a pore size of 4.5mm, and divide the tobacco stems into thin tobacco stems with a diameter of <4.5mm and thick tobacco stems with a diameter of ≥4.5mm. Tobacco stems.

[0036] Temporary storage of tobacco stems: the sieved thin tobacco stems and thick tobacco stems are stored in different temporary storage cabinets.

[0037] Thin tobacco stem processing: the temporarily stored thin tobacco stems are washed and soaked, steamed, stored, pressed, shredded, and temporarily stored. The purpose of washing and soaking stems is to increase the moisture content of the tobacco stems and remove dust on the surface of the tobacco stem...

Embodiment 3

[0041] Embodiment 3 The comparative analysis of cut stem physical index

[0042] Materials: shredded leaves of a certain brand, shredded stems obtained by 5 kinds of processing methods.

[0043] Instruments: CWT200 leaf shape measuring instrument (Zhengzhou Tobacco Research Institute), YGD450 filling value measuring instrument (Zhengzhou Jiade Electromechanical Technology Co., Ltd.), YQ-2 leaf silk vibrating sorting screen (Zhengzhou Tobacco Research Institute).

[0044] Sample Preparation:

[0045] Under the existing technological conditions, the samples were prepared as many times as possible through the reduction of different shredded stems.

[0046] Method 1, using the process of the present invention to prepare shredded stems, see Example 1 for details.

[0047] Method 2, traditional shredded stem preparation steps: blending stems, sieving tobacco stems (removing stems and thin stems <2.5mm), washing and soaking stems, steaming stems once, storing stems, steaming stems tw...

Abstract

The invention discloses a processing technology of high-curling-degree shredded cut stems. According to the technology, tobacco stems are screened into thin tobacco stems and thick tobacco stems for pre-treatment of different intensities after stem preparation, the thin tobacco stems are sequentially subjected to stem washing and soaking, stem steaming, stem storage, stem sheet pressing, stem cutting and cut stem temporary storage, and the stem pressing and stem cutting process is used, so that the crushing problem caused by re-cutting of the thin tobacco stems is avoided, and the utilizationrate of tobacco stem raw materials is effectively increased. The thick tobacco stems are sequentially subjected to stem washing and soaking, stem steaming, stem storage, stem sheet cutting, stem cutting and cut stem temporary storage, the thick cutting and thin cutting process is used, low-water-content stem cutting is carried out before feeding by using a cutting machine, the difference between cut stem sheets and traditional pressed stem sheets is small, the stem cutting machine stably operates for a long time, and the actual cut stem shredded effect is good. After pre-treatment, cut stem mixing and cut stem processing are carried out. The size and shape of the cut stems prepared through the method are highly similar to those of cut tobacco.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a processing technology for high-crimp shredded stems. Background technique [0002] Against the background of the development of cigarette harm reduction and tar reduction, slim cigarettes are increasingly accepted by the market. Because the traditional cut stem processing technology usually pursues the high filling performance of cut stems, the size and shape of cut stems and cut leaves are quite different, generally in the form of large sheets without curl. When used in the production of slim cigarettes and high-end cigarettes, due to the There are large differences in width, thickness and shredded leaves, which will make consumers feel mixed with "sundries". At the same time, due to the large and irregular shape of traditional cut stems, the uniformity of blending is poor, resulting in cigarettes A series of problems such as large fluctuations in physical indicators and poo...
