Abstract

FIELD: production of smoking tobacco articles.

SUBSTANCE: method involves providing collecting wastes; mixing and forming smoking article from resultant mix; extracting wastes with the use of liquid carbon dioxide and separating miscella; producing at least part of swollen vein by moistening tobacco vein; impregnating the latter using separated miscella and simultaneously increasing pressure; relieving pressure to atmospheric pressure value at the rate preventing freezing of carbon dioxide absorbed as part of miscella; drying.

EFFECT: increased efficiency in producing of smoking article with reduced resin and nicotine content without deteriorating of its organoleptical properties.

Description

The invention relates to a technology for the production of smoking tobacco products.

There is a method of manufacturing a smoking tobacco product, involving the preparation of bags including cut tobacco, reconstituted tobacco, expanded veins, flavorings and gumekants and the formation of a smoking product from it (Vorobyeva L.N. Technology for the production of tobacco products. Textbook for university students. - Rostov- on-Don: Publishing house of Donskoy Tabak OJSC, 2005, p. 39-56).

In this method, to reduce the tar and nicotine content in the smoking article, an expanded vein is introduced into the bags, but its content in the bag is limited by approximately 10% deterioration in the organoleptic properties of the smoking article due to the appearance of cellulose smack in the smoke.

The technical result of the invention is to obtain a smoking article with a reduced content of resin and nicotine without compromising its organoleptic properties.

This result is achieved in that in a method for manufacturing a smoking tobacco product with a reduced tar and nicotine content comprising bagging comprising at least cut tobacco and an expanded core, and forming a smoking article from it according to the invention in the process of bagging and forming a smoking article collect waste that is extracted with liquid carbon dioxide to separate miscella, and at least a portion of the expanded vein is made by wetting tobacco vein, its impregnation with separated miscella with a simultaneous increase in pressure, reduction of pressure to atmospheric pressure with a speed excluding freezing of carbon dioxide absorbed in miscella, and drying.

The method is implemented as follows.

Since the proposed technology provides for the use at the initial stage of the process of the product obtained in subsequent stages, the process can be implemented only in a continuous stream. For this, it is necessary to bring it to the steady state. It is realized by compiling a mixture of all components of the bags, except for the expanded vein, in an amount of about 3-4% by weight of the first bag and extracting it with liquid carbon dioxide with separation of miscella to obtain the first batch of expanded vein.

In steady state, the recipe components of the bags are mixed in a predetermined ratio. The resulting bag is used to form the corresponding smoking article. The resulting waste is collected and sent for extraction. The ratio of the components in the waste approximately corresponds to the ratio of the components of the bags, so when they are extracted with liquid carbon dioxide, the substances that form the taste and aroma of the manufactured product are transferred to the miscella.

The extraction and separation of miscella is carried out according to traditional technology (Mikanba V.T. Carbon dioxide extracts. - Sukhumi: Alashara, 1989, p. 26-28).

The tobacco vein is moistened to a moisture content of at least 13%, which provides sufficient elasticity for its 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 for impregnation of the tobacco vein, which is determined by the known dependences of mass transfer (Kosmodemyansky Yu.V. Processes and apparatuses of food production. A textbook for university students. - 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 extractive substances contained in miscella, which provide the vein with the flavor of the components of the bags,

After the impregnation is completed, the excess liquid phase is drained for reuse and the pressure in the tank is reduced to atmospheric pressure at a rate that excludes freezing of the absorbed carbon dioxide by analogy with the known process (RU 2002433 C1, 11/15/1993). In this case, carbon dioxide is removed and an approximately twofold increase in the volume of the vein is observed while extractives from the miscella are preserved in it. Then the vein is dried to a residual moisture content of less than 13% in accordance with known recommendations (US 5469872, 11.28.1995).

The resulting expanded core is used to completely or partially replace the expanded core obtained by traditional technology as part of the following bags of the same type of smoking article, the waste of which was used to produce the expanded core.

Subsequently, the cycle repeats.

Due to the saturation of the expanded vein with substances that are completely identical to those that form the taste and aroma of the finished product, its content in the recipe does not distort the organoleptic properties of the target product with extraneous smacks even when the amount in the bag is more than 30%, which allows replacing the cut tobacco with an expanded vein to receive smoking tobacco products corresponding to the content of tar and nicotine light and super light type.
