Problems solved by technology

[0004] In short, although there are many studies on the improvement of the quality of cut stems recently, the effect of improving the quality of cut stems is not good
Some new process technologies have high energy consumption and bring safety hazards (such as microwave leakage, etc.), which are not conducive to production and application, while chemical treatment technologies are likely to cause secondary pollution, and the cost is high, and industrial application is difficult. In biotechnology treatment, Since the biomass components such as cellulose and pectin in the tobacco stem are packaged in order, and the activities of different biological agents will inhibit each other, the direct addition of the biological agent at one time cannot satisfy the internal needs of the tobacco stem. The degraded components are effectively treated, the degradation effect is not good, and they are mainly degraded and stored on-line, without alcoholization in offline storage, the effect of aroma production is not good, and the quality improvement is not obvious. Graded biological treatment is required. After treatment, alcoholization produces aroma. In order to significantly improve the quality of cut stems

Embodiment 1

[0067] Wash the prepared tobacco stems with a neutral protease solution with a concentration of 1.0%, and store them under normal conditions for 4 hours to obtain tobacco stems with a moisture content of (19.0±1.0)%. To obtain tobacco stems with a moisture content of (27.0±1.0)%, and then use steam with a pressure of 3.0bar to rehydrate the tobacco stems to obtain expanded tobacco stems with a temperature of (60±3)°C and a moisture content of (31.0±1.0)%. , the expanded tobacco stems enter the stem pressing equipment with a pressing gap of 1.0mm for tobacco stem extrusion to obtain thick stem slices, and then use conventional feeding equipment to apply the compound enzyme solution on the thick stem slices by 2% of the weight of the tobacco stems. The activities of pectinase, cellulase and xylanase in the unit mass of the compound enzyme solution were 9 million U, 6 million U and 3 million U respectively. , stored under the condition of relative humidity of (60±5)% for 8 hours....

example 2

[0071] Wash the prepared tobacco stems with a neutral protease solution with a concentration of 1.5%, and store them under normal conditions for 6 hours to obtain tobacco stems with a moisture content of (21.0±1.0)%. Tobacco stems with a moisture content of (29.0±1.0)% are obtained, and steam with a pressure of 3.5bar is used to rehydrate the tobacco stems to obtain expanded tobacco stems with a temperature of (65±3)°C and a moisture content of (33.0±1.0)%. Enter the tobacco stem pressing equipment with a pressing gap of 1.1 mm to extrude the tobacco stems to obtain thick stem slices, and then use conventional feeding equipment to apply the compound enzyme liquid on the thick stem slices by 1.5% of the weight of the tobacco stems. The activities of pectinase, cellulase and xylanase in the mass were 15 million U, 10 million U and 5 million U respectively. Store under the condition of (60±5)% for 10 hours. After storage, use conventional feeding equipment to mix the concentratio...

Embodiment 2

[0072] The shredded stems obtained in Example 2 were analyzed and compared with the shredded stems produced by traditional techniques (washing, dampening, storing stems, increasing temperature and humidification, pressing stems, cutting shredded stems, feeding shredded stems, expanding and drying), pectin, The total amount of cell wall substances such as cellulose is reduced, the total sugar content and the total amount of aroma components are increased, the shredded stem smoke is delicate, the aroma characteristics are prominent, the concentration is moderate, the irritation is reduced, the amount of miscellaneous gas is less, the taste is comfortable, the aftertaste is clean, and the internal quality is obviously improved.

[0073]Add the shredded stems obtained in Example 2 and the traditional shredded stems (the shredded stems produced by the above-mentioned traditional craft) to Septwolves (red) cigarettes at a ratio of 12%, respectively. After the cigarettes are added with...

Abstract

The invention provides a method for improving the quality of cut stems. The method comprises the following steps that (1) tobacco stems are washed and degraded; (2) moisture regain is conducted on the tobacco stems and the tobacco stems are stored; (3) the tobacco stems are expanded and pressed; (4) stem pieces are degraded and stored; (5) material adding is conducted on the stem pieces; (6) the stem pieces are dried; (7) the dried stem pieces are stored; (8) moisture regain is conducted on the dried stem pieces and the dried stem pieces are expanded and pressed; (9) the stem pieces are cut into shreds and materials are added; (10) the cut stems are expanded and dried. Cigarettes with the cut stems prepared through the method are clear in fragrance characteristic, the fragrance quality is good, the smoke state is improved, the fine and smooth performance is improved, the harmony is better, miscellaneous gases are reduced, the dry sensation is reduced, and taste is more comfortable.

Description

technical field [0001] The invention belongs to the field of tobacco processing and relates to a processing method for improving the quality of cut stems. Background technique [0002] Shredded stems have the characteristics of low tar and nicotine content and good filling performance. They are one of the main fillers in cigarette leaf formulations and play an important role in cigarette formulations. Under the permission of product design, increasing the amount of shredded stems is one of the important means to reduce coke and harm, and it is also a good way to save costs. Cut stems are processed from tobacco stems, but because tobacco stems contain a large amount of macromolecular substances such as cellulose, pectin and lignin, these macromolecular substances are restrictive factors for improving the quality of cut stems. Traditional processing technology cannot fully degrade these macromolecular substances, nor can it control the degradation degree of these macromolecul...
