Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with specific embodiments.

[0023] The method for extracting aroma substances from flue-curing room exhaust gas provided by the present invention is realized as follows:

[0024] Place adsorbents on the vents or vents of the flue-cured tobacco house, and use these adsorbents to absorb the volatile substances volatilized from the tobacco leaves during the curing process. These volatile substances are the contents volatilized from the rupture of the glandular hairs of tobacco leaves and the cell walls of the leaves. Among them, the absorbent material is sponge or filter cotton, which is blocked on the moisture outlet or exhaust port of the flue-cured tobacco house. The sponge or filter cotton has permeability and is blocked on the exhaust port or moisture outlet, and does not affect the flue-cured tobacco house. The exhaust or dehumidification effect, and the strong adsorption capacity. Under normal circ...

Abstract

The invention discloses a method for extracting a living tobacco leaf aroma substance from tobacco curing room waste gas and a method for improving cigarette flue gas aroma. The method for extracting living tobacco leaf aroma substances comprises the following steps: putting an adsorbing material at a moisture discharge port and a gas discharge port of the tobacco curing room to adsorb volatile matters volatilized from tobacco leaves in the curing process, wherein the volatile matters are contents volatilized in the tobacco leaf tentacle and blade cell wall rupture process; collecting for 5-10 hours, and immersing the adsorbing material in dichloromethane for 4-8 hours to obtain raw liquor; and further extracting the raw liquor to obtain a liquid aroma substance. The living tobacco leaf aroma substance extracted from the tobacco curing room waste gas obviously enhance the abundance and delicacy of the cigarette flue gas aroma when being used for processing cigarettes; and thus, the method can use local materials, utilizes wastes, change wastes into valuable substances and generate great economic benefit and environmental benefit.

Description

Technical field [0001] The invention relates to the field of tobacco, in particular to a method for extracting aroma substances of living tobacco leaves from exhaust gas of a flue-curing room and a method for improving the aroma of cigarette smoke. Background technique [0002] Tobacco is one of the important economic crops in my country, and it occupies an important position in the national economic income. The tax revenue provided by the tobacco industry to the country each year ranks first among all industries in the country. [0003] However, there are some problems in the tobacco industry: [0004] (1) Tobacco shreds, slices or stalks for the production of cigarettes are obtained by roasting tobacco leaves, and the roasting steps of tobacco leaves are usually completed in a flue-curing room. According to relevant data, the planting area and output of flue-cured tobacco in my country's tobacco production ranks first in the world. The annual planting area is more than 1.1 billion...
