Embodiment 1

[0018] Weigh 100 g of flue-cured tobacco shreds and add them to the extraction container, then add 1000 g of 50% ethanol aqueous solution, soak at 30 °C for 24 h, and filter under reduced pressure to obtain tobacco extract. After the extract was evaporated to remove ethanol under reduced pressure, freeze-dried to obtain 49 g of solid tobacco extract, the dry basis yield was 56% (after deducting the moisture in the shredded tobacco, the calculated ） . Weigh 20 g solid tobacco extract and 30 g Mg(OH) 2 After mixing, add 50 g of 30% aqueous ethanol solution to fully disperse to form a viscous mixture. The viscous mixture is drum-dried, and the dried material is pulverized to obtain tobacco material suitable for heating non-burning tobacco products. The tobacco material will not burn obviously when heated at 200 ℃ ~ 400 ℃, and the thermal weight loss rate at 300 ℃ is 28%, which has the ability to effectively release smoke, and the smoke released has obvious characteristics of fl...

Embodiment 2

[0020] Weigh 60 g shredded flue-cured tobacco, 20 g shredded Burley tobacco and 20 g shredded oriental tobacco into the extraction container, then add 1500 g 80% ethanol aqueous solution, soak at 50 °C for 48 h, and filter under reduced pressure to obtain tobacco extract. The extract was evaporated to remove ethanol under reduced pressure, and then freeze-dried to obtain 41 g of solid tobacco extract, with a yield of 46% on a dry basis. Weigh 40 g solid tobacco extract and 10 g Mg(OH) 2 , 10 g Al(OH) 3 , 10 g Fe(OH) 3 and 10 g Cu(OH) 2 After mixing, add 40 g of 50% ethanol aqueous solution to fully disperse to form a viscous mixture. The viscous mixture is drum-dried, and the dried material is pulverized to obtain tobacco material suitable for heating non-burning tobacco products. The tobacco material will not burn obviously when heated at 200 ℃ to 400 ℃, and the thermal weight loss rate at 300 ℃ is 37%, which has the ability to effectively release smoke, and the smoke re...

Abstract

A tobacco material preparing method for heated non-combustion tobacco products is characterized by sequentially comprising the following steps of (1) performing digestion on tobacco raw materials with an ethanol solution and preparing a tobacco extract; (2) after the digestion, separating the solution from the tobacco to obtain a tobacco extracting solution, evaporating the extracting solution under a decompressing condition to remove ethanol, and freezing and drying to obtain a solid tobacco extract; (3) mixing the solid tobacco extract with metal hydroxide particles with a flame retarding function, adding a solvent to disperse and form a thick mixture, drying the obtained thick mixture with a roller drying method, and crushing the dried materials to obtain the tobacco material suitable for the heated non-combustion tobacco products. Smoke released due to heating at 200 DEG C to 400 DEG C from the tobacco material prepared according to the method has good satisfying feeling in both concentration and strength, and the flavor quality and sense comfort are good, and a good flame retarding action is realized.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for preparing tobacco material suitable for heating non-combustion tobacco products. Background technique [0002] Heat-not-burn tobacco products originated in the 1980s and have a history of nearly 30 years since the products were launched. After continuous technological innovation and product promotion, it has become one of the important types of new tobacco products. The smoke produced by this type of product is closer to that of traditional cigarettes, and the sidestream smoke and some harmful components are significantly reduced, making it have a certain market potential. Therefore, related technologies have become a research hotspot for foreign tobacco companies. In recent years, with the continuous increase of tobacco control efforts, foreign tobacco companies have continuously increased research and development efforts on heat-not-burn tobacco produc...
