RU2307565C1 - Method for producing of aromatized puffed tobacco stem - Google Patents

Abstract

FIELD: tobacco production and treatment process.

SUBSTANCE: method involves extracting mixture of tobacco wastes and coriander using liquid carbon dioxide; separating miscella to be used for impregnating and expanding of moistened tobacco stem. Resultant base product may be used as part of mix for tobacco smoking articles in an amount exceeding 30% since it does not impart cellulose taste when smoked through.

EFFECT: provision for obtaining of tobacco stem having increased volume.

Description

The invention relates to a technology for increasing the volume and flavoring of a tobacco vein.

There is a method of producing a flavored expanded tobacco vein, which enriches the tobacco vein with natural softeners and aromatic substances and increases its volume using water and water vapor (Tatarkhenko II, Mokhnachev I.G., Kasyanov G.I. Technology of subtropical and food flavoring products Textbook for students of universities. - M .: Academy, 2004, p.230-231).

This source does not contain information on the technological parameters of the process of increasing the volume of the vein, which probably make up the manufacturer’s know how. Moreover, since both water and water vapor are known extractants of aroma-forming substances, the absence of this information precludes the possibility of reproducing this technology and analyzing its advantages and disadvantages.

The objective of the invention is to expand the arsenal of means of production of flavored tobacco vein with an increased volume,

The technical result of the invention is to obtain a flavored tobacco vein with an increased volume.

This result is achieved by the fact that the method of producing a flavored expanded tobacco vein involves extracting a mixture of tobacco waste and coriander with liquid carbon dioxide and separating the miscella, moistening the tobacco vein, impregnating the separated miscella with a simultaneous increase in pressure, reducing the pressure to atmospheric pressure at a rate that provides freezing into the absorbed the composition of the miscella of carbon dioxide, and heating at a speed that ensures the sublimation of carbon dioxide, to obtain the target product.

The method is implemented as follows.

Tobacco waste is mixed with coriander, extracted with liquid carbon dioxide and the miscella is separated according to traditional technology (Mikanba V.T. Carbon dioxide extracts - Sukhumi: Alashara, 1989, p. 26-28). The ratio of the mixed components is set by any necessary to obtain a given shade of aroma. In this case, the specific yield of extractives from the mixture exceeds the specific yield of extractives when the components are extracted separately due to the implementation of the coextraction effect, which does not depend on the ratio of the components of the mixture (Kasyanov GI, Theoretical Foundations of CO ₂ Processing of Plant Raw Materials. - M .: Rusoz 1994, p. 48-49).

The tobacco vein is moistened to a moisture content of at least 13%, which provides sufficient elasticity for expansion (US 5469872, 11.28.1995). The moistened vein is loaded into an airtight container into which miscella is served. The pressure in the tank automatically rises to a value corresponding to the pressure of saturated vapor of carbon dioxide at the temperature of the miscella. The resulting mixture is incubated for a time sufficient to impregnate the tobacco vein, which is determined by the known laws of mass transfer (Kosmodemyansky Yu.V. Processes and apparatuses of food production. Textbook for students of technical schools. - M .: Kolos, 1997, p.135-162) . As a rule, it is no more than 15 s (US 5469872, 11.28.1995). In this case, carbon dioxide is absorbed and the vein is saturated with the extractives contained in the miscella, which provide the vein with aroma. To achieve the desired content in the vein, which is determined according to well-known recommendations (N.V. Puzdrova Theoretical justification and development of a system for assessing and regulating the quality of smoking products. Abstract of thesis, Ph.D. - Krasnodar: KubGTU - Pogarskaya Cigarette - cigar factory ", 2004, p.15-16), according to the above regularities, the concentration of extractives in miscella and the phase ratio at the stages of extraction and impregnation are calculated.

After the impregnation is completed, the excess liquid phase is drained for reuse and the pressure in the vessel is reduced to atmospheric pressure at a rate that provides freezing of the absorbed carbon dioxide by analogy with the well-known process for the production of non-aromatic veins of increased volume (Tatatarchenko I.I., Mokhnachev I.G., Kasyanov GI Technology of subtropical and food flavoring products. A textbook for university students. - M .: Academy, 2004, p.229-230). The vein is reloaded from the tank into the expansion tower and heated at a speed that ensures sublimation of carbon dioxide, for example, by contact with a gaseous coolant with a temperature of at least 90 ° C, as in the above technology (Tatarkhenko I.I., Mokhnachev I.G., Kasyanov GI Technology of subtropical and food flavoring products. Textbook for university students. - M.: Academy, 2004, p.230). In this case, carbon dioxide is removed and approximately twofold increase in the volume of the vein is observed while the extractive substances of miscella are preserved in it.

As a result, the vein obtained by the described technology has a given content of aromatic substances combined with the aroma of tobacco smoke (Vorobyova LN, Tobacco products manufacturing technology. A manual for university students. - Rostov-on-Don: Publishing House Donskoy Tabak, 2005, p. 53-56).

The product obtained according to the described technology does not create a taste of cellulose when smoked, which allows it to be used in the composition of tobacco smoking bags in an amount of more than 30%, which ensures the production of light type tobacco products.

Thus, the proposed method allows to obtain a tobacco vein with consumer properties identical to the vein obtained by known technology.
