Problems solved by technology

The rolling method mainly uses mechanically crushed tobacco stems to make tobacco powder, then adds adhesives, and then presses them into pancakes by pressing rollers. The pancakes are cut into shreds and used for cigarette processing. Although this process is simple, the tobacco stems produced Silk quality is low and can only be used in the production of low-grade cigarettes
The papermaking method is to boil the tobacco stems and grind them into pulp, mix them with recycled tobacco leaf pulp, and use the papermaking method to form them on a paper machine to produce paper-like tobacco sheets, and then cut the tobacco sheets into shredded tobacco and mix them with shredded tobacco leaves Cigarettes; the production process of this shredded tobacco is complicated, the yield is low, the production cost is high, and the pollution to the environment is great
The puffing method is mainly to cut the tobacco stems into short stems with a length of no more than 30mm, and then undergo high-temperature steam puffing treatment at 250-350°C. The disadvantage of this treatment method is that it greatly damages the smell of the smoke and cannot obtain good-quality tobacco stems. Silk
There is also a defibrillation method that first soaks the tobacco stems in hot water at 60-70°C, and after filtration and separation, the solid tobacco stems are subjected to multiple defibrillations to obtain shredded tobacco stems. During the fibering process, the tobacco components will be destroyed, resulting in low quality tobacco and low production efficiency
In summary, the existing methods described above are either complex in process, or the shredded tobacco stems produced have low yield and low quality.

Embodiment 1

[0032] Take 30g of tobacco stems, pre-cut them into 2-3.5cm stem segments, put them in hot water for soaking treatment, the temperature of the water bath is 60°C, soak for 30min, adjust the moisture content of the tobacco stems to 50wt%, filter, and carry out PFI refiner Silk processing, the speed is 1000rmin -1 , the resulting shredded tobacco stems are put into a 200-mesh mesh bag, extruded for 3 minutes under the pressure of 0.3 MPa in a hydraulic press, then the shredded tobacco stems are dispersed by a disperser, and air-dried at room temperature until the water content is about 13wt%. Through the 6-mesh and 40-mesh vibrating sieves, the oversized particles and the undersized powders were screened out, and the shredded tobacco stems of -6 mesh to +40 mesh were obtained. The distribution of shredded tobacco stems and the yield of qualified shredded tobacco stems are shown in Table 1. and shown in Table 8. The resulting shredded tobacco stems were doped in shredded tobacco...

Embodiment 2

[0036] Take 30g of tobacco stems, pre-cut into 3-4.5cm stem segments, put them in boiling water for soaking treatment, soak for 20min, adjust the moisture content of the tobacco stems to 55wt%, filter, and perform PFI silking treatment at a speed of 2000rmin -1 , the resulting shredded tobacco stems are put into a 200-mesh mesh bag, extruded for 3 minutes under the pressure of 0.3 MPa in a hydraulic press, then the shredded tobacco stems are dispersed by a disperser, and air-dried at room temperature until the water content is about 13wt%. Through the 6-mesh and 40-mesh vibrating sieves, the oversized particles and the undersized powders were screened out, and the shredded tobacco stems of -6 mesh to +40 mesh were obtained. The distribution of shredded tobacco stems and the yield of qualified shredded tobacco stems are shown in Table 2. and shown in Table 8. The obtained shredded tobacco stems were doped in shredded tobacco at a mass ratio of 20%:80% to make a trial cigarette ...

Embodiment 3

[0040] Take 10g of tobacco stems, pre-cut them into 3-5cm stem segments, put them into sealed bags, add appropriate amount of tap water, place them in the steam chamber of the electric cooking pot, steam them with water at 108°C for 10min, and put the tobacco stems Moisture is adjusted to 50wt%, after steaming is finished, cool down, then carry out PFI silk-forming treatment, the rotating speed is 1500rmin -1 , the resulting shredded tobacco stems are put into a 200-mesh mesh bag, extruded for 3 minutes under the pressure of 0.3 MPa in a hydraulic press, then the shredded tobacco stems are dispersed by a disperser, and air-dried at room temperature until the water content is about 13wt%. Through the 6-mesh and 40-mesh vibrating sieves, the oversized particles and the undersized powders were screened out, and the shredded tobacco stems of -6 mesh to +40 mesh were obtained. The distribution of shredded tobacco stems and the yield of qualified shredded tobacco stems are shown in T...

Abstract

The invention discloses a threadlike tobacco stem making method based on a PFI refiner and application of threadlike tobacco stems. The threadlike tobacco stem making method includes the steps of sequentially carrying out precutting, humidification processing, PFI refiner threadlike tobacco stem forming, extrusion, scattering, air drying and screening on tobacco stems to obtain the threadlike tobacco stems, and doping made threadlike tobacco stems into cut tobaccos to form cigarettes in a rolling connection mode. The content of carbonic oxide in cigarette making smoke can be effectively reduced. The threadlike tobacco stem refining technology based on the PFI refiner is simple and rapid, the obtained threadlike tobacco stems are high in productive rate and quality, and the requirements of industrial production are met.

Description

technical field [0001] The invention relates to a method for preparing shredded tobacco stems based on a PFI refiner and the application of shredded tobacco stems, belonging to the technical field of tobacco processing. Background technique [0002] Tobacco stems are the thick and hard veins and petioles of tobacco leaves, accounting for about 25% to 30% of the leaf weight. As a big tobacco producing country, hundreds of thousands of tons of tobacco waste are discarded in my country every year, which not only pollutes the environment, but also causes a great waste of resources. The current main utilization form of tobacco stems is to extract nicotine, solanesol, and make tobacco flakes. [0003] At present, the traditional methods for preparing shredded tobacco stems from tobacco stems are mainly the method of shredding tobacco stems to make stem slices, which include the following methods: rolling method, papermaking method, and puffing method. The rolling method mainly u...
