Method and device for improving quality and yield of cut stems produced through microwave expanded tobacco stems

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...

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

[0011] In the slicing process, due to the uneven density of the tobacco stem after microwave expansion, the tobacco stem cannot be uniformly compacted before slicing, and the area with a low degree of compaction will be taken out by the cutter during slicing. Shaped tobacco stems are cut into stalk slices during the subsequent shredding, which need to be separated and removed again in the subsequent process to form waste, which increases the consumption of expanded tobacco stems in the process of making shredded tobacco, and reduces the yield of finished shredded stems
