Example Embodiment

[0016] Example one

[0017] Weigh 300g of flue-cured tobacco leaves and place them in a 10-liter container, add 6000ml of 90% ethanol, place them at 25°C, and seal and soak for one week. Use filter paper to filter under reduced pressure to remove particulate matter such as tobacco dust in the solution. Distill under reduced pressure at 40°C. After concentration, a first-level tobacco leaf extract C is obtained. The filtered tobacco leaves are dried at 25° C. to remove ethanol to obtain soaked tobacco leaf A.

[0018] The prepared soaked tobacco leaf A is placed in an airtight container, and then heated gradually from room temperature to 300°C, and after the temperature is raised to 300°C, it is maintained for 30 minutes. The volatile gas in the flue gas is volatilized, and the volatile gas is collected through a container connected with 95% ethanol, and distilled under reduced pressure at 50°C. A highly volatile secondary tobacco leaf extract D is obtained. Then, the soaked to...

[0022] Weigh 300 g of air-cured tobacco leaves and place them in a 10-liter container, add 6000 ml of 90% ethanol, place them at 25° C., and seal and soak for one week. Use filter paper to filter under reduced pressure to remove particulate matter such as tobacco dust in the solution. Distill under reduced pressure at 40°C. After concentration, a first-level tobacco leaf extract C is obtained. The filtered tobacco leaves are dried at 25° C. to remove the ethanol to obtain soaked tobacco leaf A.

[0023] The prepared soaked tobacco leaf A is placed in an airtight container, and then heated gradually from room temperature to 300°C, and after the temperature is raised to 300°C, it is maintained for 25 minutes.

[0025] Example three

[0026] The present invention includes the following steps:

[0027] (1) Seal and soak the tobacco leaves at a mass ratio of tobacco leaf: ethanol at a ratio of 1:20, the soaking temperature is 30°C, and the soaking time is 20 days;

[0028] (2) After the end of soaking, the ethanol is separated from the tobacco leaves to obtain soaked tobacco leaf A and soaking liquid. The soaking liquid is concentrated under reduced pressure to a relative density of 1.10 to obtain a first-level tobacco leaf extract C. The mass percentage is used for concentration. 75% ethanol is used as the solvent; the obtained first-level tobacco extract C is some alcohols, phenols, ethers, nitriles, ketones, aldehydes, acids, esters, etc. Large volatile and semi-volatile tobacco aroma substance.

[0029] (3) Put the soaked tobacco leaf A at room temperature to dry to remove the ethanol, then place the dried soaked tobacco leaf A in an airtight container and gradually increase the temperatur...

Abstract

The invention belongs to the technical field of tobaccos, in particular relates to a preparation method of tobacco leaves of a smokeless and fireless cigarette, comprising the following steps of: (1) soaking the tobacco leaves in ethanol, wherein the mass ratio of the tobacco leaves to the ethanol is 1:10 to 1:40; (2) after the soaking is ended, separating the ethanol from the tobacco leaves to obtain soaked tobacco leaves A and a soak solution, and concentrating the soak solution to obtain a first-stage tobacco leaf extractive C; (3) placing the soaked tobacco leaves A in a closed container to heat, and collecting volatile gas through a container containing the ethanol to obtain a high-volatile second-stage tobacco leaf extractive D; (4) raising the temperature of the soaked tobacco leaves A from 300 DEG C to 450 DEG C, and then slowly reducing the temperature of the soaked tobacco leaves to room temperature to obtain second-stage tobacco leaves B; (5) mixing the first-stage tobacco leaf extractive C and the second-stage tobacco leaf extractive D to obtain blended standby tobacco leaves E; and (6) mixing the soaked tobacco leaves A and the second-stage tobacco leaves B, and blending to obtain standby tobacco leaves F. The preparation method provided by the invention is free of generation of smoke and passive smoking harm to nonsmokers.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for preparing tobacco leaves of smokeless and fireless cigarettes. Background technique [0002] The hazards of cigarettes are well known. Incomplete combustion of cigarette leaves produces smoke. According to existing literature, there are more than 4,000 substances in smoke, of which there are more than 30 known direct carcinogenic chemicals in smoke, of which The biggest one is tobacco tar. The chemical composition of tobacco tar itself is very complex. For cigarette smoke, it generally refers to tar and other chemical components wrapped by it, including nicotine, carbon monoxide, nitrogen dioxide, tritetrabenzoarsenic, Nitric oxide and aromatic hydrocarbons that are too late to vaporize. The harm of cigarettes to human beings has been paid more and more attention by people. At the same time, the harm of second-hand smoke to non-smoking groups cannot be ...
