Method and device for processing tobacco stems

Abstract

The invention discloses a treatment method and a treatment device for tobacco stems. The processing method of the tobacco stems mainly includes the steps of material preparation, solid heat medium mixing, expansion treatment, and separation. By mixing the tobacco stems with solid heat medium and high-temperature gas heat medium, they are irradiated with microwaves, and the gas, solid heat medium and microwave radiation are irradiated. High-quality expanded tobacco stems can be obtained by simultaneously heating the inside and outside of the tobacco stems according to the common practice; the processing device is provided with sequentially connected feeding equipment, a closed vibrating conveyor, a microwave stem expanding device, and a vibrating screening machine. Tobacco stems mixed with solid heat medium, high-temperature gas heat medium are fed into the stem expansion device, and microwaves are emitted, so that the gas, solid heat medium and microwave irradiation can heat the inside and outside of the tobacco stem simultaneously, thereby obtaining high-quality expansion. Tobacco stems.

Description

technical field [0001] The invention relates to a treatment method and a treatment device for tobacco stems, in particular to a treatment method and a treatment device for expanded tobacco stems. Background technique [0002] Tobacco stems are a by-product of the tobacco industry and a valuable natural resource. my country is a big tobacco country, and a large amount of tobacco stem resources are discarded every year, which not only causes environmental pollution, but also wastes natural resources. Studies have shown that the types of ingredients contained in tobacco stems are basically the same as those of tobacco leaves. However, tobacco stems are made into shredded stems, which have low filling value, insufficient aroma, and high irritation. Further research has found that the above shortcomings can be overcome after tobacco stems are expanded. Therefore, a lot of research has been done on tobacco stem expansion in China at present. [0003] CN1518906A discloses a pretr...
