Technology for treating expanded stems

Abstract

The invention discloses a technology for treating expanded stems, belongs to the technical field of shred making of tobacco, and in particular relates to the technical field of shred making with tobacco stems. The technology comprises the following steps of: soaking the tobacco stems, storing the stems, quantitatively feeding, heating and humidifying, slicing the stems for the first time, temporarily storing the stem slices, discharging the stem slices, cutting the stems into shreds for the second time, quantitatively feeding, adding the primary stem shreds, storing the stem shreds, quantitatively feeding, drying, and performing secondary flavoring, thus obtaining a stem shred finished product. The obtained product has the advantages of good bulkiness, low breaking rate, low production cost, pure aroma, high filling value, light wood mixed gas, comfortable mouthfeel, soft smoke, capability of reducing tar of cigarettes and good compatibility with the tobacco shreds.

Description

technical field [0001] The invention belongs to the technical field of shredded tobacco production, in particular to the technical field of shredded tobacco stem production. Background technique [0002] At present, expanded tobacco stems have been widely used in the production of cigarettes. The advantages of expanded tobacco stems make their value increasingly prominent. The main performance is that expanded tobacco stems can effectively reduce the carbon monoxide and tar produced when cigarettes are burned and smoked. The purpose of reducing tar and harm and improving the safety of cigarette products; the bitterness, spicy taste, irritation and miscellaneous gas of tobacco stems are significantly reduced after puffing, so that the smoking quality of cut stems is improved; after expansion treatment, cut stems will It becomes soft and bulky, and the content of stems and stem sticks in the shredded stems is reduced, thereby improving the purity of the cut stems; after puffin...

AI Technical Summary

Problems solved by technology

The expansion uniformity of the product obtained by the microwave treatment process without expansion medium is poor; the microwave expansion process using solid medium is difficult to operate during the expansion operation, and the suction quality of the product will be affected to a certain extent; The safety and environmental protection requirements of the expansion agent are high, and the expansion agent is easy to remain in the product; the method of cutting the stem slices and then cutting the stems is only suitable for the tobacco stems after microwave expansion, and due to the simple process, it is not conducive to the control of stems. The stability of silk quality; In addition, in the above-mentioned technology, due to the rapid drying of the tobacco stems at high temperature, the internal chemical composition of the tobacco stems has changed greatly, and the natural aroma has been seriously lost. Flavoring of shredded stems often adopts end-flavoring. It is difficult for the added spices to penetrate deeply at room temperature, which brings great difficulties to the blending of shredded stems and shredded tobacco, and it is easy to affect the uniformity of shredded tobacco blending, The physical indicators of cigarettes and the sensory quality of smoking have a relatively large negative impact, and with the increase in the blending ratio of cut stems, (the amount of foreign tobacco stems in mixed cigarettes is about 20% to 45%, and the amount of cigarettes in China , the dosage is about 5% to 30%,) the negative impact is becoming more and more serious, so there are great restrictions on the use of shredded stems produced by the existing technology, which greatly affects the quality of finished cigarettes
