Problems solved by technology

[0010] The technical problem to be solved by the present invention is that, for new tobacco products such as existing electronic cigarettes and heat-not-burn cigarettes, the gap between traditional cigarettes in terms of mouthfeel and aroma, such as insufficient smoke (smoked) taste, insufficient richness of aroma (such as charcoal, etc.) The main aroma of traditional cigarettes such as incense, burnt sweet, etc. is missing or not obvious), and the aroma is not harmonious enough, natural and other technical problems

Embodiment 1

[0035] Close the valve B of the special retort pyrolysis cooling device in advance (the condensation collection device is not used in this embodiment), open the valve A, keep the cooling temperature (water used as coolant) at a constant temperature of 4°C, and keep the heating temperature at a constant temperature of 230°C. System tightness. Weigh 50g of 60-mesh Hunan Jiangyong 2014 flue-cured tobacco C3F powder and quickly put it into a special retort pyrolysis cooling device, immediately seal the system, and at the same time turn on the stirring motor and adjust the speed to 250 rpm to stir the tobacco raw materials. After heating for 25 minutes, Remove the heat source, after the dry distillation pyrolysis bottle is naturally cooled, add 6 times the weight of 95% ethanol aqueous solution at 60°C, stir and reflux for extraction for 2.5 hours, after releasing the extract, add 5 times the weight of 95% ethanol aqueous solution at 60°C Stir and reflux for extraction for 1.5h, re...

Embodiment 2

[0060] Close in advance the valve B of the special retort pyrolysis cooling device (same as embodiment 1) capable of bearing pressure (the present embodiment does not use the condensation collection device), open the valve A, and keep the cooling temperature (using ethylene glycol aqueous solution as coolant) constant temperature to -5°C, the heating temperature is constant to 260°C, and the airtightness of the system is checked. Weigh 50g of 20-mesh Zimbabwe 2014 L1O grade flue-cured tobacco powder and quickly put it into a special retort pyrolysis device, immediately close the system, and at the same time turn on the stirring motor and adjust the speed to 300 rpm to stir the tobacco raw materials. After heating for 20 minutes, put Remove the heat source, and after the dry distillation pyrolysis bottle is naturally cooled, add 6 times the weight of 60% ethanol-40% ethyl acetate solution, stir and reflux at 60°C for 3 hours, and after releasing the extract, add 5 times the weig...

Embodiment 3

[0063] Cut the self-made flue-cured tobacco leaf group with a shredder twice, and sieve about 1mm 2 Left and right size smoke slices. Close the valve B of the special retort pyrolysis cooling device (same as embodiment 1) in advance (the condensation collection device is not used in this embodiment), open the valve A, and keep the cooling temperature (using ethylene glycol aqueous solution as the coolant) at a constant temperature of -10°C , The heating temperature is constant to 330°C, and the airtightness of the system is checked. Put the above 1mm 2 After quickly adding 60g of left and right large and small tobacco pieces into the special dry distillation pyrolysis direct cooling device, immediately close the system, and at the same time turn on the stirring motor and adjust the speed to 600 rpm to stir the tobacco raw materials. After heating for 15 minutes, remove the heat source. After the dry distillation pyrolysis bottle is naturally cooled, add 5 times the weight of...

Abstract

The invention discloses a preparation method of tobacco-derived basic smoke flavor raw material. The technical scheme of the invention is to carry out dry distillation and pyrolysis of tobacco raw materials in a closed system at 180-365° C.; and then extract aroma substances from the tobacco raw materials after dry distillation and pyrolysis. The extracted product and its further refined product are the tobacco-derived basic smoke flavor raw materials. This raw material is applied to new tobacco products, which not only has the natural aroma of tobacco, but also can significantly increase the aroma characteristics of new tobacco products, such as smoky aroma, burnt aroma, and roasted aroma, making it closer to traditional cigarettes. The raw material can also be applied to traditional cigarettes. The invention has the advantages of simple process, economical safety, obvious application effect and broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for preparing tobacco-derived basic smoke flavor raw materials. Background technique [0002] According to reports, there are currently nearly 1 billion smokers in the world, and the number of smokers in China exceeds 350 million. These smokers mainly smoke traditional cigarettes. When traditional cigarettes are burned, through substance volatilization, pyrolysis and high-temperature synthesis, there are as many as 7,300 compounds in the smoke, of which 2,740 are produced by high-temperature combustion (the highest temperature is nearly 900°C), and some of these substances are related to the characteristics of tobacco. Fragrance is related, but some substances are harmful to the human body (such as CO, benzo[α]pyrene, fused-ring aromatic hydrocarbons, etc.). [0003] Recently, due to the continuous rise of the anti-smoking movement, smoking and the environm...
