Problems solved by technology

[0011] None of the above microwave-expanded tobacco stem processing methods can remove the higher-density tobacco stems in microwave-expanded tobacco stems
In the process of making expanded tobacco stems, the cut stems made of high-density tobacco stems cannot be eliminated. After these high-density cut stems are mixed with shredded tobacco to make cigarettes, cigarettes containing high-density cut stems will cause puncture of cigarette paper and bursting. Problems of mouth, uneven burning speed, poor quality of smoking, and increased release of cigarette smoke tar
[0012] However, in the existing air separation equipment, the separated lighter and effective materials are separated by pipeline transportation and gas-material separation device. During the transportation and separation process, the moisture content of the material is reduced, and the mechanical friction is severe, resulting in the size of the material becoming smaller. , and produce a large amount of powder, which reduces the use value of the material, and is not suitable for the separation of microwave-expanded tobacco stems with low moisture content and easy breakage

Embodiment 3

[0054] Example 3 :like image 3 As shown, the tobacco stems are expanded by microwaves, 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 microwave-expanded tobacco The moisture content of the stalk reaches 18-20%, and the high-density tobacco stalks are removed by the wind separator, and then the tobacco stalks are sliced, the slice thickness is 0.8mm, the stalks are shredded, and the width of the stalks is 0.2mm, and the stalks are dried to a moisture content of 13-14%. Obtain finished stem shreds.

Embodiment 4

[0055] Example 4: like Figure 4 As shown, the tobacco stems are expanded by microwave, the volume increases by 200-350%, the moisture reaches 3-5%, and the temperature is 75-90°C. The produced tobacco stems with low expansion rate and high density are separated, and the tobacco stems with low density and high expansion rate are increased to 20-25% by a damper, and then stored for 1-3 hours and fed quantitatively. , Warming and humidifying to a moisture content of 25-28% and a temperature of 55-70°C, cut into stalks with a thickness of 0.3mm, temporarily store the stalks, row the stalks, cut the stalks into shredded stalks with a width of 0.9mm, and feed quantitatively , feeding cut stems, storing cut stems for 1-6 hours, quantitative feeding, drying, and flavoring cut stems to obtain finished cut stems.

Embodiment 5

[0056] Example 5 :like Figure 5 As shown, the tobacco stems are heated and humidified to a moisture content of 12-15% and a temperature of 65-70°C, and then expanded by microwaves, the volume increases by 200-350%, the moisture reaches 3-5%, and the temperature is 75-90°C. The warehouse-type air separation equipment separates the tobacco stems with low expansion rate and high density caused by deterioration, high moisture, and uneven microwave irradiation. Increase to 20-25%, store the stems for 1-6 hours, straighten the stems, cut them into slices with a thickness of 0.2mm, feed the slices, store the slices for 1-4 hours, cut the slices into shredded stems with a width of 0.9mm, The shredded stems are shaped and dried, and the shredded stems are flavored to obtain the finished microwave-expanded shredded stems.

[0057] The shredded stems or granular stems obtained through the above five examples can be blended into shredded tobacco according to the formula ratio, and fin...

Abstract

The invention discloses a method and equipment for removing high-density tobacco stem in microwave expansion tobacco stem, in particular relates to the technical field of manufacturing cut stems by utilizing the microwave expansion tobacco stems and belongs to the technical field of tobacco manufacturing. According to the tobacco stems subjected to microwave expansion, the tobacco stems with low expansion rate and high density in the microwave expansion tobacco stems are removed through the wind action, wherein the wind speed is 8-14m / s during separation. The expansion tobacco stems with uniform density can be obtained after separation, the manufactured cut stem is high in filling value and uniform in density, after the cigarette is added, the within-batch fluctuation of the cigarette smoke tar release amount can be reduced, the within-batch stability of the cigarette smoke tar release amount is improved, and the open seam phenomenon during cigarette combustion is reduced.

Description

technical field [0001] The invention relates to a method and equipment for removing high-density tobacco stems from microwave-expanded tobacco stems, in particular to the technical field of producing shredded 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 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 methods can realize the continuous production of microwave expansion of tobacco stems, but because the microw...
