Problems solved by technology

[0003] At present, shredded stems are widely used in conventional cigarettes (24.2-24.6 mm in circumference), but in slim cigarettes (16.8-17.4 mm in circumference), no application has been found due to factors affecting their physical shape. In other words, the size of cut stems used in conventional cigarettes is too large and the uniformity of blending is poor, which ultimately has a great impact on the sensory quality of cigarettes
[0004] In the cut stem processing and manufacturing method disclosed in the prior art, the microwave expansion method is used to prepare the cut stem. Using the microwave expansion method requires high energy consumption, complicated process, and requires separate investment in the construction of a production line, and the investment in equipment is relatively large.
[0005] In some methods, a grinding machine or a double-roller grinding machine is used to rub the silk, but the fiber tissue cells of the tobacco stems are destroyed by the silk rolling process, which affects the elasticity of the stems, and the raw material loss of the tobacco stems is large, and the yield of the stems is low.
In addition, this method also uses the microwave expansion method, which requires high energy consumption and complicated processes.
[0006] In addition, there is also the problem that the shredded tobacco stems are relatively high

Embodiment 1

[0066] Such as figure 1 Shown, a kind of processing method of shredded stem for thin cigarette, concrete steps are as follows:

[0067] 1) The tobacco stems are soaked with a soaking machine, and the tobacco stems are soaked with water at 60±5°C. The soaking time is 60-150s, and the flow rate of the tobacco stems is 2600-3200kg / h. Moisture at 25-31%;

[0068] 2) After washing the tobacco stems, steam the stems to loosen the tissue, increase softness and resistance to crushing, and then store the stems. The process parameters are controlled as follows:

[0069] project unit skills requirement steam pressure MPa 0.5-0.8 Tobacco stem moisture after steaming ％ 32-38 Discharge temperature ℃ 85-90 Storage time h 2-48

[0070] 3) Slitting the stored tobacco stems into stem slices with a thickness meeting the technical requirements, the thickness of the cut stem slices: 0.16-0.22 mm.

[0071] 4) Add prefabricated feed liquid A to the s...

Embodiment 2

[0093] 1) Obtain quantitative tobacco stems, wash with water to remove tobacco powder and non-tobacco impurities, and each process parameter is controlled as follows:

[0094] project unit skills requirement washing time s 60-150 washing water temperature ℃ 40-70 stem flow kg / h 2600-3200 Tobacco stem moisture after washing ％ 25-31

[0095] 2) After washing the tobacco stems, steam the stems to loosen the tissue, increase softness and resistance to crushing, and then store the stems. The process parameters are controlled as follows:

[0096] project unit skills requirement steam pressure MPa 0.5-0.8 Tobacco stem moisture after steaming ％ 32-38 Discharge temperature ℃ 85-90 Storage time h 2-48

[0097] 3) Mechanically press the tobacco stems whose water content meets the process requirements to the thickness required by the process, and the thickness is 1.0-1.6mm.

[0098] 4) Slitting ...

Embodiment 3

[0116]A processing system for shredded cigarette stems, including a stem dipping machine for rinsing tobacco stems, a tobacco stem moisturising machine that provides a steam pressure of 0.5-0.8MPa, a first storage cabinet, a first cutting device, and a feeding device , the second storage cabinet, providing a cut stem expander with a steam pressure of 0.4-0.8MPa, a shred drying machine for drying stem slices, a cut stem air separator for sorting stem sticks and stem pieces in stem slices, The second cutting equipment, cut stem screening machine, the above equipments are connected through the conveying equipment in turn, or set up independently, the conveying mechanism can be a belt conveyor or a vibrating conveyor, after the cut stems are screened, the The shredded stems are sent into the third storage cabinet for storage.

[0117] The above-mentioned processing system shows how the cut stems are processed in each equipment, the work efficiency is high, the obtained cut stems m...

Abstract

The invention discloses a method and system for processing cut stems for fine cigarettes. After tobacco stems are subjected to primary slicing, feeding, swelling, drying and winnowing, the stem slices are subjected to secondary slicing, and the width of the cut stems obtained after secondary slicing is 0.8-1.2 mm; aiming at the fine cigarettes, secondary slicing is adopted, proper cut stem forms are effectively obtained, the obtained cut stems are low in wood smell, wet, fine, smooth and permeable in smoke, free of pungent stimulation and burning heat sensation, smooth in throat entering, clean and comfortable in remaining taste and good in universality and compatibility, meanwhile, the whole cut rate of the cut stems is effectively guaranteed, and the breakage rate is reduced. The whole system and method take the two purposes into consideration, and high practicality is achieved. According to the processing system, all equipment can be independently arranged or connected through conveying equipment, and conveying efficiency is effectively improved.

Description

technical field [0001] The invention relates to cigarette manufacturing, in particular to a method and system for processing shredded stems for thin cigarettes. Background technique [0002] Tobacco stems are an important part of tobacco leaves, and the tobacco stems accounting for about 25% of the mass of tobacco leaves can be obtained by separating the stems. High-quality shredded stems can increase the filling value of shredded tobacco, improve combustibility and smoke characteristics, reduce the tar content of smoke, and reduce the cost of cigarettes. Therefore, the effective use of tobacco stems to prepare high-quality shredded stems has always been the focus of research and discussion in the tobacco industry. [0003] At present, shredded stems are widely used in conventional cigarettes (24.2-24.6 mm in circumference), but in slim cigarettes (16.8-17.4 mm in circumference), no application has been found due to factors affecting their physical shape. In other words, t...
