Problems solved by technology

[0005] Tobacco stem processing in cigarette factories adopts more technological processes, such as rehydrating the tobacco stem, storing the stem, cutting the stem, feeding the stem, expanding the stem, and adding flavor, that is, the processing technology of "cutting first and then expanding". Tobacco stems of different sizes are processed at the same time, and the same process and parameters are used to rehydrate the tobacco stems. The uniformity of moisture resurfacing is poor and the energy consumption is high. The difference is large, and most of them are sheet cut stems; the shap...

Embodiment 1

[0044] The preparation of embodiment 1 cut stems for tobacco

[0045] Take a mixture of 1000kg of tobacco stems, screen them, expand them with microwaves, and control the expansion rate at 30%, wash the stems with warm water at 55°C (the water velocity is 0.70m / s, and the frequency of the bottom band is 18Hz), and then enter the pressure wet stems, The steam pressure is controlled at 0.15MPa, and the moisture is controlled at 32%.

[0046] The tobacco stems after pressure moistening are pressed, the gap between the pressing rollers is set at ≤0.7mm, and the stems are directly cut into shredded stems with a width of 0.07mm, and then the shredded stems are added with spices. %, store the stems in a cache cabinet (at a temperature of 26° C. and a humidity of 50%) for 1.5 hours.

[0047] Then, the tube-sheet drum-type silk drying is adopted, the hot air temperature is 110°C, the cylinder wall temperature is 120°C, the outlet temperature is 50°C, the rotating speed is 35Hz, and th...

Embodiment 2

[0049] The preparation of embodiment 2 cut stems for tobacco

[0050] Take a mixture of 1000kg of tobacco stems, screen them, expand them with microwaves, and control the expansion rate at 20%, wash the stems with warm water at 60°C (the water flow rate is 0.65m / s, and the frequency of the bottom belt is 20Hz), and then enter the pressure wet stems, The steam pressure is controlled at 0.10MPa, and the moisture is controlled at 30%.

[0051] The tobacco stems after pressure moistening are pressed, and the gap between the pressing rollers is set as: ≤0.7mm, and the stems are directly cut into shredded stems with a width of 0.08mm, and then the shredded stems are added. %, store the stems in a cache cabinet (at a temperature of 26°C and a humidity of 50%) for 1.0h.

[0052] Then, the tube-sheet drum-type silk drying is adopted, the hot air temperature is 112°C, the cylinder wall temperature is 135°C, the outlet temperature is 55°C, the rotating speed is 30Hz, and the flow rate i...

Embodiment 3

[0054] Embodiment 3 Preparation of shredded tobacco stems

[0055] Take a mixture of 1000kg of tobacco stems, screen them, expand them with microwaves, and control the expansion rate at 50%, wash the stems with warm water at 50°C (the water velocity is 0.75m / s, and the frequency of the bottom band is 15Hz), and then enter the pressure wet stems, The steam pressure is controlled at 0.20MPa, and the moisture is controlled at 35%.

[0056] The tobacco stems after pressure moistening are pressed, the gap between the pressing rollers is set at ≤0.7mm, and the stems are directly cut into shredded stems with a width of 0.06mm, and then the shredded stems are added with spices. %, store the stems in a cache cabinet (at a temperature of 26° C. and a humidity of 50%) for 2 hours.

[0057] Then, the tube-sheet drum-type silk drying is adopted, the hot air temperature is 115°C, the cylinder wall temperature is 130°C, the outlet temperature is 60°C, the rotating speed is 25Hz, and the flo...

Abstract

The invention relates to the technical field of tobacco processing and in particular relates to cut stems for cigarettes and a preparation method thereof as well as the cigarettes. The preparation method comprises: carrying out size screening, microwave expansion, stem washing, pressure stem wetting, ultrafine stem pressing, stem cutting, cut stem feeding and cut stem storage on tobacco stem material to obtain a cut stem crude product; taking the cut stem crude product and carrying out cut stem drying; winnowing, adding aroma into the cut stems and storing the cut stems to obtain the cut stems for the cigarettes. According to the preparation method provided by the invention, a previous stem size is pre-treated; meanwhile, expanded stems with a specific specification are obtained through utilizing a microwave technology; then the cut stem crude product is obtained through adopting an ultrafine stem pressing and primary shredding technology; finally, the filiform cut stems are obtained through utilizing a pipe plate drying technology. An experiment result shows that compared with the cut stems prepared by a traditional method, the cut stems for the cigarettes, prepared by the method, have the advantages that the sensory quality is greatly improved, the color and luster are improved, the aroma quantity is more sufficient, odor and irritation are alleviated, the aftertaste is more comfortable, and the ratio of doping the cut stems into cut tobaccos is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a shredded tobacco stem, a preparation method thereof and a cigarette. Background technique [0002] Tobacco stems are an important component of tobacco leaves, and after separation of stem leaves, tobacco stems accounting for about 25% of the total weight of tobacco leaves can be obtained. The types of chemical components contained in tobacco stems are basically the same as those in tobacco leaves. Shredded stems are used as the filling material of cigarettes, which can reduce the tar content of cigarettes. [0003] In the prior art, there are many methods for producing shredded stems, most of which go through steps such as washing the stems, storing the stems, moistening the stems, feeding, increasing temperature and humidity, pressing the stems, cutting the stems, expanding, and adding flavor. The key in these steps is expansion, that is, to make the shrunken cut ...
