Abstract

This invention discloses a composition and equipment method for extracting tobacco waste through thermal decomposition, comprising the following extraction raw materials: tobacco waste, liquor, natural aroma extract, extracting liquid, and deionized water; the specific formula includes the following extraction raw materials: 100-200g tobacco waste, 10-20g liquor, 1-2g natural aroma extract, 30-50g extracting liquid, and 80-100g deionized water; the raw materials of this invention undergo fermentation, thermal decomposition, extraction, and concentration processes. The fermentation stage has a low temperature, resulting in the retention of more aroma components in the extract. Solid-liquid separation is performed before the thermal decomposition reaction, making the entire thermal decomposition process highly efficient, short in time, and with minimal loss of extracted aroma components, thereby improving the extraction rate to over 98%. Simultaneously, the tobacco waste is combined with other raw materials, utilizing the solubility of nicotine to allow the nicotine in the tobacco waste to be transferred sequentially to the liquor and extracting liquid. The addition of natural aroma extract further enhances the preparation of a tobacco composition with high nicotine and high aroma content.

Description

Technical Field

[0001] This invention relates to the field of tobacco extraction technology, specifically to a tobacco composition obtained by thermal decomposition and extraction of tobacco waste and its preparation method. Background Technology

[0002] Cigarettes are an important component of new tobacco products, characterized by: firstly, low-temperature heating (300°C-500°C) without combustion; secondly, the provision of nicotine to meet consumers' physiological needs; and thirdly, a reduction of over 90% in most harmful components in cigarette smoke compared to traditional cigarettes, largely satisfying consumers' physiological smoking needs and reducing the impact on the external environment, thus gaining positive market access. However, because heating at low temperatures reduces the release of aroma substances from tobacco itself, and the amount of aroma derivatives formed under heating conditions is also less, their contribution to aroma and flavor indicators is not significant. Therefore, adding functional flavorings is an important means of enhancing and preserving the aroma of cigarettes.

[0003] Currently, the production of tobacco flavorings and fragrances mainly involves artificial synthesis and extraction from natural plants and animals. The application of artificially synthesized tobacco flavorings and fragrances is limited due to safety concerns. While natural tobacco flavorings extracted from plants and animals can meet safety requirements, their production costs are high due to limitations in raw material sources, and compared to traditional cigarettes, they suffer from poorer flavor compatibility and integration. Therefore, it is necessary to improve extraction processes and enhance the integration of extracts with cigarettes. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the purpose of this invention is to provide a tobacco composition obtained by thermal decomposition and extraction of tobacco waste and its preparation method, so as to solve the problems mentioned in the background art.

[0005] The present invention solves the technical problem by adopting the following technical solution:

[0006] This invention provides a tobacco composition obtained by thermal decomposition and extraction of tobacco waste, comprising the following extraction raw materials:

[0007] Tobacco waste, liquor, natural aroma extracts, leachate, deionized water;

[0008] Its specific formula includes the following raw materials: 100-200g tobacco waste, 10-20g liquor, 1-2g natural strong aroma extract, 30-50g extract, and 80-100g deionized water.

[0009] Preferably, the tobacco composition obtained by thermal decomposition and extraction of tobacco waste comprises the following extraction raw materials:

[0010] 150g tobacco waste, 115g liquor, 1.5g natural aroma extract, 40g extract, 90g deionized water.

[0011] Preferably, the tobacco waste is one or more of the following: waste tobacco stems, tobacco stalks, tobacco dust, tobacco seeds, waste tobacco leaves, and low-grade tobacco that cannot be processed into cigarettes.

[0012] Preferably, the liquor is selected from one or more of the following: Moutai, Wuliangye, Langjiu, Luzhou Laojiao, Wulingjiu, Jiannanchun, Jinliufu, Tianzhilan, Yanghe Daqu, Gujinggong, Xiaohutuxian, and Tuopai Qujiu.

[0013] Preferably, the natural fragrance extract is selected from one or more of rose extract, jasmine extract, osmanthus extract, clove extract and artemisia extract.

[0014] Preferably, the extract is a mixture of ethanol (70-80% by volume), propylene glycol (80-90% by volume), or ethanol and propylene glycol in a volume ratio of 1:1 to 1:2.

[0015] This invention also provides a method for preparing a tobacco composition obtained by thermal decomposition and extraction of tobacco waste, comprising the following steps:

[0016] Step 1: Take tobacco waste and wash it 2-3 times with deionized water, then crush it into particles of 2-3cm using a pulverizer, and let it dry naturally to form tobacco powder.

[0017] Step 2: Sterilize the fermentation tank, then add tobacco powder and white wine in proportion, mix slowly and evenly, and then seal and ferment in the fermentation tank at 20-25℃ for 6-12 hours. The tobacco waste, natural aroma extract and white wine are fermented together.

[0018] Step 3: Open the sealed lid and add the fermented material to the extraction liquid in proportion. Mix well and then extract. Next, separate the solid and liquid of the extracted raw material to obtain the filtrate. Then heat the filtrate to 50-60℃ for 2-4 hours to decompose.

[0019] Step 4: After the decomposed filtrate is left to stand, take the supernatant and distill it under reduced pressure at a temperature of 30-45℃ and a pressure of 0.1-0.12MPa. After concentration and cooling, collect the tobacco composition.

[0020] Preferably, after preparing the fermentation tank, the tank lid is closed, all pipes and valves except for the steam at the bottom of the tank are closed, and steam is introduced into the tank for sterilization. When the temperature rises to 120-130℃, the steam supply to the bottom of the tank is turned off, and after keeping it warm for 10 minutes, the exhaust valve is opened to cool it down.

[0021] Preferably, the material can be extracted twice or multiple times. During extraction, the material is placed on an ultrasonic extractor with a power of 2000-3000W and ultrasonically vibrated for 20-30 minutes. The extract is collected to obtain extract A. The extract is added to the obtained filter residue twice or multiple times and ultrasonically vibrated and collected. Finally, the extracted extract A collected multiple times is poured into a fermentation tank.

[0022] Preferably, the collected tobacco composition is added to tobacco shreds, cigarette paper, and filter rod, and the amount of tobacco composition added accounts for 0.002%-0.05% of the weight of the cigarette.

[0023] This invention relates to a tobacco composition obtained by thermal decomposition and extraction of tobacco waste and its preparation method. The raw materials of this invention undergo fermentation, thermal decomposition, extraction, and concentration processes. The fermentation stage involves low temperatures, resulting in higher retention of aroma components in the extract. Solid-liquid separation is performed before the thermal decomposition reaction, leading to a highly efficient and short-duration thermal decomposition process with minimal loss of extracted aroma components, thus increasing the extraction rate to over 98%. Simultaneously, the tobacco waste is combined with other raw materials, utilizing the solubility of nicotine to sequentially transfer nicotine from the tobacco waste to the liquor and the extraction liquid, ultimately dissolving most of the nicotine. The concentrated filtrate is then combined with the addition of a natural aroma extract to prepare a tobacco composition with high nicotine and superior aroma content.

[0024] Compared with existing technologies, the present invention has the following advantages:

[0025] This invention combines tobacco waste, natural aroma extracts, and baijiu (Chinese liquor) during fermentation to extract and separate a composition from tobacco residue, achieving the recycling of waste resources, greatly reducing production costs, and possessing good economic value. At the same time, the aroma of baijiu is mixed into the composition through fermentation and thermal decomposition aging. When used, the aroma substances are evenly infiltrated into the tobacco leaves, making the tobacco leaves more mellow and achieving a full fusion of the aroma of baijiu and the aroma of natural plants.
