Abstract

FIELD: production of smoking tobacco articles with reduced resin and nicotine content.

SUBSTANCE: method involves providing tobacco mixing, during which process collecting wastes and extracting with the use of liquid nitrogen; separating miscella; producing at least part of swollen vein by moistening tobacco vein; impregnating it with separated miscella and simultaneously increasing pressure; thereafter, reducing pressure to atmospheric pressure value and drying; forming smoking article from swollen vein and cut tobacco.

EFFECT: reduced resin and nicotine content of smoking article without deteriorating its organoleptical properties.

Description

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

A known method of manufacturing a smoking tobacco product, comprising composing a bag including cut tobacco, reconstituted tobacco, expanded vein, flavorings and gumekants and forming a smoking article from it (Vorobyeva LN, Production technology of tobacco products. Textbook for students of universities - 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 low tar and nicotine content, comprising bagging comprising at least cut tobacco and expanded core, and forming a smoking article from it according to the invention in the process of bagging and forming waste products are collected from it of a smoking article, which are extracted with liquid nitrogen to separate miscella, and at least a part of the expanded vein is made by moistening the tobacco LKI, impregnating the separated miscella while increasing the pressure to atmospheric pressure reduction 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% of the mass of the first bag and extracting it with liquid nitrogen with the 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 nitrogen, 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 nitrogen vapors at the temperature of the miscella. The resulting mixture is incubated for a time sufficient for the 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, pp. 135-162) . As a rule, it is no more than 15 s (US 5469872, 11.28.1995). In this case, nitrogen is absorbed and the vein is saturated with extractive substances contained in the 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 vessel is reduced to atmospheric. In this case, nitrogen 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 vein is used to completely or partially replace the expanded vein obtained by traditional technology as part of the following bags of the same type of smoking article, the waste of which was used to obtain the expanded vein,

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.
