Description

one

The invention relates to the technology of post-harvest processing of tobacco in tobacco-producing households and in fermentation plants.

There is a known method for producing a smoking product from green tobacco leaves, which involves carrying out drying operations, moisture and lidro-heat treatment.

In order to reduce the time required for cleaning and reducing the laboriousness of the process, according to the proposed method, the fresh leaves of tobacco are dried at a temperature of 80-100 ° C for 2-4 hours. Then crushed and subsequently treated with organic solvents: petroleum ether, sulfuric ether and ethyl alcohol, followed by drying, and moistening and hydro-heat treatment is carried out after drying.

The treatment with solvents is carried out at a temperature of from 20 ° C to the boiling point of each solvent.

Hydro-braking is carried out at a material moisture of 15-18% and a temperature of 70-90 ° C for 1-5 hours.

The proposed method is carried out as follows.

Tobacco is removed from plants during the ripening period of the middle leaves of the leaves, dried at 80-100 ° C for 2-4 hours and crushed.

The crushed material is sifted through a L 018 sieve. The screened tobacco powder is treated alternately with the following solvents: 1) petroleum ether (temperature 1 petroleum ether 20-45 ° C, processing time 1.5-12 h), 2) sulfuric ether (temperature sulfur ether 20-36 ° С, Processing times 1-5 h), 3) ethyl alcohol (temperature of ethyl alcohol 20-78 ° С, time

processing 1,5-8 h). Ethyl alcohol can be replaced by acetone (acetone temperature 20-56 ° C, processing time 1-8 hours).

On 1 weight. including tobacco snag take 2-3 hours dissolve. Extraction process lead

whether it is continuously intermittently with the necessary constant mixing of the components. The tobacco treated with three solvents is dried, ventilated to remove residual eluants, moistened to 15-18% and

subjected to hydro-thermal treatment in an autoclave at a temperature of 70-90 ° C for 1-5 hours

The smoking product prepared in this way is used to make a smoking product in the form of reconstituted tobacco leaf, for example, by injection molding.

Example: 532 freshly harvested technically mature tobacco leaves, quickly dried without soaking in a drying chamber at 85 ° C

Claims (4)

for 3 h, grind and sieve through a sieve with a side size of the openings of 0.18 mm. The tobacco powder is placed in an extractor with a mixer, poured over 200 hours, petroleum ether with a boiling point of 45 ° C, heated the mixture to a boil and treated with 2 hours of boiling solvent. Chestrole pairs are condensed in a reflux condenser installed above the extractor. At the end of the treatment, the tetrol ether with the extractive substances dissolved therein is removed by filtration and 200 parts of sulfuric ether are poured into the extractor. The tobacco powder is treated for 1.5 hours with boiling (T - 36 ° C) sulfuric ether, and then 2 hours. boiling (T - 78 ° C) ethanol, which is also taken 200 hours. Extracted tobacco powder is heated for 1 hour at 75 ° C and actively ventilated to remove residual ethanol, cooled to 20 ° C, added with careful prymeshivannya 15 hours of water, is loaded into an autoclave and subjected to hydro-thermal treatment at a temperature of 75 ° C for 3 hours. Extracted and subjected to hydrothermal processing of tobacco powder from green becomes light brown and acquires a characteristic odor otfermentirovan new tobacco. At the same time there is a change in its chemical composition. In comparison with the initial powder, the processed tobacco powder loses 10.8% of solids, i.e. no more than when processed in a known manner. At the same time, it is relatively reduced (in terms of dry matter, the content of nitrogen-containing substances negatively affecting the quality of tobacco: total nitrogen by 16.2%, proteins by 21.9%, nicotine by 30.6%. Some loss of water-soluble carbohydrates and polyphenols does not affect negatively on the tasting benefits of a smoking product made from tobacco powder. Claim 1. A method for producing a smoking product from green tobacco leaves, including drying, moistening and hydrothermal processing, characterized in that To reduce the time of post-harvesting and reduce its labor intensity, freshly harvested tobacco leaves are subjected to drying at a temperature of 80-100 ° C, after drying, they are crushed and subsequently treated with organic solvents: petroleum ether, sulfuric ether and ethyl alcohol, followed by drying, and moistening hydrothermal treatment is carried out after drying. 2. A method according to claim 1, characterized in that the drying is carried out until the full dehydration of the midrib of the leaves for 2-4 hours. 3. A method according to claim 1, characterized in that the treatment with solvents is carried out from 20 ° C to the boiling point of each solvent. 4. A method according to claim 1, characterized in that the hydrothermal treatment is carried out at a moisture content of the material of 15-18% and C for 1-5 hours.
