Problems solved by technology

[0010] The above Chinese patent microwave expanded tobacco stem processing methods all cannot remove the higher density tobacco stems in the microwave expanded tobacco stems, and cannot remove the cut stems made of high-density tobacco stems in the process of making expanded stems. After the shredded tobacco is added to make cigarettes, cigarettes containing high-density shredded stems will have problems such as piercing the cigarette paper, bursting, uneven burning speed, poor smoking quality, and increased release of cigarette smoke tar

Example Embodiment

[0045] Example 1: Such as figure 1 As shown, the volume of the tobacco stems expanded by microwave increases by 200-350%, the moisture reaches 3-5%, and the temperature is 75-90℃. After washing the stems, the moisture is increased to 25-30%, and then the tobacco stems are sliced, The slice thickness is 0.2mm. After the process of winnowing, the high-density stems, tobacco stems, and end of the stems are removed. After storage for 1-3 hours, they are cut into stems with a width of 0.8mm. After microwave recovery, the moisture content is reduced to 10— 12%, after regaining moisture and adding fragrance, the water content of the stalks is controlled at 12.5-13.5% to make finished stalks for blending.

Example Embodiment

[0046] Example 2 :Such as figure 2 As shown, the tobacco stems are expanded by microwave, the volume increases by 200-350%, the moisture content reaches 3-5%, the temperature is 75-90℃, after cooling and setting, storage and aging for 7-60 days, and then moisture regain to make the tobacco stem moisture To reach 18-20%, the tobacco stems are sliced ​​with a thickness of 0.8mm. After a winnowing process, the high-density stems, tobacco stems, and stem ends are removed. The stems are cut into shreds with a width of 0.2mm, and the stems are dried to moisture 13-14%, to get finished stalks.

Example Embodiment

[0047] Example 3 :Such as image 3 As shown, the tobacco stems are expanded by microwave, the volume increases by 200-350%, the moisture reaches 3-5%, the temperature is 75-90℃, the moisture is increased to 30-35% after soaking, and then the stems are stored for 1-3 hours, Quantitative feeding, increasing temperature and humidity to 32-38% moisture content, temperature 55-70℃, cut into 0.3mm thick stem pieces, temporary storage of stem pieces, after winnowing process, remove high-density stem pieces, tobacco stems, and stems At the end, the stalk slices and stalk slices are cut into stalks with a width of 0.9 mm, quantitatively fed, stalks are added, and the stalks are stored for 1-6 hours, quantitatively fed, dried, and the stalks are flavored to obtain the finished stalks.

Abstract

The invention relates to a method and a device for improving the quality and the yield of cut stems produced through microwave expanded tobacco stems, particularly to the technical field of cut steam production through microwave expanded tobacco stems, and belongs to the technical field of tobacco production. According to the method and the device, in the expanded tobacco stem cutting process, a winnowing process exists between a slicing process and a cutting process, expanded tobacco stems which are not cut into stem pieces yet, expanded stem pieces of high density or tobacco stem powder are separated through a wind separation device, then, separated materials are subjected to slicing in the slicing process again, consumption that the expanded tobacco stems are sliced into the stem pieces in the cutting process is reduced, setting of follow-up processes to reject the stem pieces is avoided, and the yield of cut steam products in the expanded tobacco stem cutting process is improved. The stem pieces of even density can be obtained after separation, the produced cut stems is high in filling value, even in density and capable of reducing in-batch fluctuation of the release amount of cigarette tar in smoke, improving inter-batch stability of the release amount of cigarette tar in smoke and reducing open seams during combustion of cigarettes when being added to cigarettes.

Description

technical field [0001] The invention relates to a method and equipment for improving the quality and yield of cut stems made from microwave-expanded tobacco stems, in particular to the technical field of making cut stems from microwave-expanded tobacco stems, and belongs to the technical field of tobacco manufacturing. Background technique [0002] Chinese patent CN2607033Y discloses a multi-wave source multi-feeder microwave expansion tobacco stem device. [0003] Chinese patent CN1518906A discloses a method for expanding tobacco stems with microwaves after mixing tobacco stems with microwave low-loss solid medium particle heat medium. [0004] Chinese patent CN 202077560 U discloses a drum-type continuous microwave expansion device for tobacco stems, which can realize continuous transportation of tobacco stems by using a material conveying roller. [0005] The above Chinese patent methods can realize the continuous production of microwave expansion of tobacco stems, but b...
