Problems solved by technology

Because the particulate matter in the exhaust gas adsorbs a large amount of aroma substances, these substances are also wasted when the dust filter is used to filter the particulate matter; the absorbent used absorbs many impurities and harmful gases while absorbing the aroma-causing substances. When the absorbent is subjected to molecular distillation, some harmful substances are similar to the molecular free paths of the flavors and fragrances to be extracted, resulting in many impurities in the obtained fragrance substances; moreover, many aroma-causing components contained in them are extremely small, and it is difficult to obtain them by effective distillation ; In addition, there are dozens of aroma-causing substances in the exhaust gas, which makes the molecular distillation process extremely cumbersome

Embodiment 1

[0017] A cigarette factory extracts tobacco flavors and fragrances from processing waste gas. The specific operation steps are as follows:

[0018] 1. The exhaust gas from the cigarette factory passes through the activated carbon fiber layer 30mm and the adsorbent layer 80mm successively at a flow rate of 0.7m / s. The adsorbent layer is composed of cellulose acetate tow for tobacco and potassium chloride grains; The mass ratio of fiber tow and potassium chloride grain is 8.5:1.

[0019] ② Rinse and wash the activated carbon fiber layer. The washing solution is an aqueous solution of tea polyphenols with a mass concentration of 0.8%. After the activated carbon fiber layer is rinsed, it can be used again. The stirring speed is 300r / min, and it is divided into three layers, the upper layer is tobacco leaf powder, the middle layer is an aqueous solution, and the lower layer is an insoluble organic solution, and the middle layer and the lower layer contain precipitation;

Embodiment 2

[0025] A cigarette factory extracts tobacco flavors and fragrances from processing waste gas. The specific operation steps are as follows:

[0026] 1. The exhaust gas from the cigarette factory passes through the activated carbon fiber layer 35mm and the adsorbent layer 90mm successively at a flow rate of 0.8m / s. The adsorbent layer is composed of cellulose acetate tow and potassium chloride grains for cigarettes; The mass ratio of fiber tow and potassium chloride grain is 8.7:1.

[0027] ② Rinse and wash the activated carbon fiber layer. The washing solution is an aqueous solution of tea polyphenols with a mass concentration of 1.0%. After the activated carbon fiber layer is rinsed, it can be used again. The stirring speed is 350r / min, and it is divided into three layers, the upper layer is tobacco leaf powder, the middle layer is an aqueous solution, and the lower layer is an insoluble organic solution, and the middle layer and the lower layer contain precipitation;

Embodiment 3

[0033] A cigarette factory extracts tobacco flavors and fragrances from processing waste gas. The specific operation steps are as follows:

[0034] 1. The exhaust gas from the cigarette factory passes through the activated carbon fiber layer 40mm and the adsorbent layer 100mm successively at a flow rate of 0.9m / s. The adsorbent layer is composed of cellulose acetate tow and potassium chloride grains for cigarettes; The mass ratio of fiber tow and potassium chloride grain is 9:1.

[0035] ② Rinse and wash the activated carbon fiber layer. The washing solution is an aqueous solution of tea polyphenols with a mass concentration of 1.2%. After the activated carbon fiber layer is rinsed, it can be used again. The stirring speed is 400r / min, and it is divided into three layers, the upper layer is tobacco leaf powder, the middle layer is an aqueous solution, and the lower layer is an insoluble organic solution, and the middle layer and the lower layer contain precipitation;

Abstract

The invention discloses a method for extracting tobacco essence and flavor from processing waste gas of a cigarette factory. An active carbon fiber layer, tobacco acetate fibers and potassium chloride are used for absorption, the active carbon fiber layer is eluted through a tea polyphenol aqueous solution, the gas passing an adsorbent layer is introduced into the tea polyphenol aqueous solution for washing, an organic solution is extracted and added into saturated syrup of glycerol, and the tobacco essence and flavor is manufactured through drying; the method enables harmful matter to be extracted completely, the manufactured tobacco essence and flavor contains a small number of impurities, good in grain heat stability, not prone to moisture absorption and degeneration, long in storage life, convenient to use and soft and pure in flavor, has unique and natural tobacco fragrance, is low in irritation can effectively make up for fragrance component reduction caused by reduction of tar, and improves taste of cigarettes.

Description

technical field [0001] The invention belongs to the technical field of raw material preparation of tobacco flavors and fragrances, and in particular relates to a method for extracting tobacco flavors and fragrances from cigarette factory processing waste gas. Background technique [0002] Tobacco flavors and fragrances play an important role in solving the problem of reducing the aroma components of cigarettes due to the reduction of tar. At present, the main sources of tobacco flavors are: flavors extracted from tobacco, non-tobacco natural flavors, and synthetic flavors. The cost of extracting spices from tobacco is high, and there are hundreds of aroma substances in cigarettes, and some of them are unique components in tobacco. It is difficult to compound these flavors well with non-tobacco natural flavors and synthetic flavors, which can improve the taste of cigarettes There are still many defects in the aspect of rectifying the miscellaneous gas of cigarettes.
