Problems solved by technology

[0010] None of the above microwave-expanded tobacco stem processing methods can remove the higher-density tobacco stems in the microwave-expanded tobacco stems. After being made into cigarettes, cigarettes containing high-density cut stems will have problems such as puncture of cigarette paper, cracking, uneven burning speed, poor smoking quality, and increased release of cigarette smoke tar
[0011] The above microwave expanded tobacco stem processing methods will produce some tobacco stems that cannot be cut into slices after the expanded tobacco stems are sliced. When the stem slices are shredded, these tobacco stems will be cut into stem slices, and the subsequent process cannot be effectively removed. After these stalks are mixed with shredded tobacco to make cigarettes, the cigarettes containing stalks will have problems such as cracking, uneven burning speed, and poor smoking quality.
[0012] However, after the shredded powder enters the cigarette, it will increase the release of cigarette smoke tar and reduce the safety of the cigarette.

Embodiment 1

[0066] Embodiment 1: as figure 1 As shown, the volume of the tobacco stem after microwave expansion increases by 200-350%, the moisture reaches 3-5%, and the temperature is 75-90°C. After washing the stem with water, the moisture is increased to 25-30%, and then the tobacco stem is sliced. The thickness of the slice is 0.2mm, and after storage for 1-3 hours, it is cut into cut stems with a width of 0.8mm. Reduce it to 10-12%, after regaining moisture and adding fragrance, the moisture content of the shredded stems is controlled at 12.5-13.5%, and the finished shredded stems are made into finished stems for blending.

Embodiment 2

[0067] Embodiment 2: as figure 2 As shown, the tobacco stem is expanded by microwave, the volume increases by 200-350%, the moisture reaches 3-5%, the temperature is 75-90°C, it is cooled and shaped, stored and aged for 7-60 days, and then rehydrated to make the tobacco stem moisture. To reach 18-20%, then slice the tobacco stems, the thickness of the slices is 0.8mm, the stems are shredded, the width of the shreds is 0.2mm, the stems are dried to a moisture content of 13-14%, and the high-density stems are removed through the air selection and screening process , flaky shredded stems, and the end of stems to obtain finished shredded stems.

Embodiment 3

[0068] Embodiment 3: 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°C, the moisture is increased to 30-35% after soaking, and then the stems are stored for 1-3 hours, Quantitative feeding, temperature increase and humidification to 32-38% moisture content, temperature 55-70°C, cut into stalks with a thickness of 0.3mm, and then temporarily store the stalks, row the stalks, and cut the stalks into 0.9mm wide stalks Shredded, quantitative feeding, feeding of cut stems, storage of cut stems for 1-6 hours, quantitative feeding, drying, and flavoring of cut stems, after wind selection and screening process, high-density cut stems, flake cut stems, and end stems are removed. After microwave recovery and shaping, the finished shredded stems are obtained.

Abstract

The invention relates to a method and device for improving purity of a stalk filament prepared through microwave expansion, and particularly to the technical field of manufacturing the stalk filament from a tobacco stalk by utilizing the microwave expansion, belonging to the technical field of tobacco manufacturing. The method comprises the following steps of: A, setting a wind sorting procedure after a shredding procedure in the process of manufacturing stalk filaments from tobacco stalks through the microwave expansion, removing high-density stalk filaments through a wind sorting device in the wind sorting procedure, and carrying the stalk powder in a dust removal system by a wind force in the wind sorting device; B, removing sheet-like stalk filaments from the material without the high-density stalk filaments and stalk powder by a screening device in a screening procedure; and C, collecting materials without the high-density stalk filaments, the sheet-like stalk filaments and the powder after the wind sorting procedure and the screening procedure so as to obtain expanded stalk filaments with relatively high purity.

Description

technical field [0001] The invention relates to a device for improving the purity of cut stems made from microwave-expanded tobacco stems, in particular to the technical field of producing cut stems by using 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 CN202077560U 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 methods can realize the continuous production of microwave expansion of tobacco stems, but because the microwave energy field h...
