Problems solved by technology

Taking the 8 cigarette production plants of Henan China Tobacco Group as an example, each production plant produces about 2 tons of soaking water every day, which not only wastes a lot of fresh water resources, but also pays high sewage treatment costs
[0004] Because tobacco stems contain a large number of different types of chemical substances, the stem soaking water contains a large amount of tobacco stem extracts through soaking and washing the tobacco stems. Generally speaking, the nicotine content in it is relatively high , and these substances are the original aroma substances of tobacco. If they are directly discarded, it is easy to cause a waste of a large amount of tobacco aroma resources. Therefore, there have been some preliminary research work on the recycling of tobacco steeping water, but it is not yet simple and mature. A report on the process directly used in cigarette production

Embodiment 1

[0014] In order to test the actual improvement effect of the present invention, the inventors first analyzed and detected the chemical components of the aroma substances in the soaking water, which is the waste water produced after the flue-cured tobacco stems in production are soaked in hot water at 60°C for 50s. , the detection procedure and brief process are as follows: Weigh 20mL of steeping water into a 100mL separatory funnel, add 15mL×3 dichloromethane for extraction, combine the organic phase, add anhydrous sodium sulfate to dry, filter, concentrate to 1mL, and carry out GC / MS analysis.

[0015] The analysis conditions are: GC conditions, chromatographic column, DP-5MS (50 m×0.32 mm×0.25 μm) capillary column; inlet temperature, 250 ℃; carrier gas, helium, flow rate 1 ml / min (constant flow mode) ; Injection volume, 1 μl, temperature program, 50 ℃ (1 min), 4 ℃ / min, 160 ℃ (5 min), 4 ℃ / min, 260 ℃ (10 min); split ratio 10:1. Solvent delay 5 min; interface temperature, 280 ...

Embodiment 2

[0020] Based on the analysis of the chemical composition of the steeping water, taking the steeping water with the same chemical composition of the aroma substance as in Example 1 as an example, the inventor conducted a further experimental test on the recycling method of the tobacco steeping water.

[0021] The specific process is as follows:

[0022] Soak flue-cured tobacco stems in hot water at 60°C for 50s, let stand to cool, filter, and apply them to the flue-cured tobacco in the feeding process at the ratio of 2wt%, 3wt%, and 4wt%, respectively, in place of the existing water In the type tobacco leaves, it is added in the feeding process, and the tobacco leaves are the lower tobacco leaves (because the lower tobacco leaves have less aroma and contain less aroma substances, so the effect is more obvious), three groups of samples were made, and the unadded tobacco leaves were used as As for the control sample, the shreds were dried and rolled into cigarettes respectively. ...

Abstract

The invention belongs to the technical field of tobacco production and particularly relates to a tobacco stem soaking water recycling method. The method includes: preprocessing discarded stem soaking water in existing tobacco production, and spraying to 2-4w% of the preprocessed water to stem shreds or leaves to replace existing water used in the stem dampening, leaf dampening or feeding process. The stem soaking water contains various fragrant matters such as nicotine, organic acids, aldoketones, esters and alcohols and. The stem soaking water is directly applied to the dampening or feeding process of the cigarette technique innovatively; the requirements for resource saving and environment protection are met; cost on sewage treatment is greatly saved. The method is simple to operate, regulating cigarette process equipment is not required, no burden is caused to the existing cigarette production process, smoking quality of cigarettes can be significantly improved, operability is high, and application value and economic and social values are significant.

Description

technical field [0001] The invention belongs to the technical field of tobacco production, and in particular relates to a method for recycling tobacco stem steeping water. Background technique [0002] Stem soaking is a process in the process of making shredded stems in the cigarette industry. The method is to wash and soak dry and rough tobacco stems in hot water at about 60 degrees for about 50 seconds before transporting them to a storage cabinet for storage. , so that the tobacco stems are soaked and washed, and swelled by absorbing water. The moisture content, flexibility, and additive resistance of the washed tobacco stems are enhanced. Stem soaking water is the hot water in the sink used to soak the tobacco stems. [0003] In the current cigarette production process, the soaking water is generally classified as production sewage, which needs to be purified before being discarded. Taking the 8 cigarette production plants of Henan China Tobacco Group as an example, e...
