Problems solved by technology

[0004] Tobacco material is used as a carrier and does not require the combustion of tobacco leaves and other substances. Therefore, at present, the main tobacco raw materials are mainly different types of reconstituted tobacco leaves, and there are few studies on substances such as cut stems.

preparation example Construction

[0028] The embodiment of the present invention provides a method for preparing cut stems with relatively high concentration, the flow chart is as follows figure 1 shown, including the following steps:

[0029] (1) The raw tobacco stems are fed and screened, and the size of the tobacco stems is greater than 4 15mm;

[0030] (2) Use the mixed aqueous solution containing the atomizing agent to wash and soak the raw tobacco stems after screening, and concentrate the mixed aqueous solution after washing and soaking the stems, and separate the water and the concentrated tobacco containing the atomizing agent. liquid;

[0031] (3) Squeezing and shredding the raw tobacco stems that have undergone stem washing and soaking;

[0032] (4) Adding concentrate to the raw tobacco stems that have been processed by pressing and shredding;

[0033] (5) Drying and expanding the processed raw tobacco stems.

Embodiment 1

[0043] Embodiment 1 of the present invention provides a method for preparing cut stems with a relatively high concentration, comprising the following steps:

[0044] (1) Quantitative feeding of raw tobacco stems, unpacking, and screening of tobacco stems with a size of 10 15mm size;

[0045] (2) Washing and soaking of stems: Use a mixed solution of 45°C water and atomizing agent (propylene glycol and glycerin, volume ratio 2:1) for washing and soaking of stems; the ratio of water to atomizing agent is 2:1, mix The ratio of the solution to the tobacco stems is 1.1:1 to ensure that the tobacco stems are fully infiltrated by the mixed solution, and the infiltration time is 60 minutes. After washing and soaking the stems, the mixed solution is distilled and concentrated, the concentrated solution is ready for use, and the recovered water and atomizing agent can be recycled.

[0046] (3) Stem pressing and shredding: the gap between pressing rollers is 0.8 mm, and the thickness o...

Embodiment 2

[0054] Embodiment 2 of the present invention provides a method for preparing cut stems with relatively high concentration, comprising the following steps:

[0055] (1) Quantitative feeding and unpacking of the raw tobacco stems, the size of the tobacco stems is 10×15mm;

[0056] (2) Washing and soaking of stems: use a mixed solution of 60°C water and atomizing agent (glycerin) for washing and soaking of stems; the ratio of water to atomizing agent is 3:1, and the ratio of mixed solution to tobacco stems is 1.1:1 , to ensure that the tobacco stems are fully infiltrated by the mixed solution, and the infiltration time is 45 minutes. After the mixed solution is distilled and concentrated, the concentrated solution is ready for use, and the recovered water and atomizing agent can be recycled.

[0057] (3) Pressing stems and shredding: the gap between pressing rollers is 1.0 mm, and the thickness of stems is 0.10 mm.

[0058] (4) Feeding treatment: The mass percentage of feed is ...

Abstract

The invention provides a preparation method of cut stems with relatively high concentration. The preparation method comprises the following steps of: feeding and screening raw material tobacco stems;carrying out stem cleaning and stem dipping processing with mixed aqueous solution containing a nebulizer, and carrying out concentration processing on the mixed aqueous solution subjected to stem cleaning and stem dipping processing; carrying out stem pressing and shredding processing; carrying out charging processing; and carrying out drying expansion processing. The invention further provides application of the cut stems with the relatively high concentration. The prepared cut stems are used for conventional cigarettes; or the prepared cut stems and common tobacco shreds or a tobacco raw material added with the nebulizer are prepared into formula tobacco shreds which are used in heating noncombustible cigarettes. The preparation method is depended on conventional cigarette cut stem process equipment and utilizes an immersion wetting effect of the tobacco stems and water to promote interaction of the tobacco stems and the nebulizer so as to obtain the cut stems with 5 to 10% of nebulizer content; and the cut stems have the characteristic of relatively high smoke concentration, and not only can be used for the conventional cigarettes, but also can be used for the tobacco shreds ofthe heating noncombustible cigarettes.

Description

technical field [0001] The invention relates to the technical field of tobacco technology, [0002] In particular, the present invention relates to a method for preparing cut stems with high concentration and its application. Background technique [0003] Tobacco stems are the veins of tobacco, accounting for about 20% of the total weight, and the main components are cellulose, pectin and a small amount of tobacco aroma substances. In the traditional tobacco processing technology, tobacco stems are mainly used as fillers or raw materials for the production of reconstituted tobacco leaves. The addition ratio of shredded stems and expanded shredded stems in the cigarette formula is 10%, which mainly plays the role of adjusting the structure and combustion state of shredded tobacco, and can also optimize smoke and reduce the tar content of cigarettes. In recent years, with the development of the modern cigarette industry, new types of tobacco, especially heat-not-burn tobacco...
