Description

 The invention relates to the food industry, in particular, to aromatization of tobacco and tobacco products.

 Known methods of flavoring tobacco and devices for their implementation (Japanese patents 58-10069, 58-11191, 59-29228, 59-43155, 60-6194, 60-6198, 60-25466, 60-36275, 60-49476, 60- 54029, 61-39031; US patents 4360032, 4391284, 4458699; ed. St. USSR 1105171, 1313523, 1472037), which use various aromatic substances of plant and chemical origin.

 Known devices, for example, by autosvid. USSR 1313523, can not be used when using menthol flavoring due to its possible crystallization, clogging of holes, contamination of industrial premises with flavoring vapors due to intense evaporation.

 The device for autosvid. The USSR 1105171 and 1472037 are bulky, require additional production facilities, when using menthol flavoring it is necessary to clean and rinse equipment from contamination with menthol flavoring, high consumption of menthol, high laboriousness.

 In devices according to Japanese patents 60-25466, 60-54029, menthol or its solutions cannot be used as a flavoring, as equipment, production facilities are contaminated, large production areas and high flavoring consumption are required.

 Closest to the proposed are a method and a device for producing flavored menthol cigarettes according to technological instruction TI 10-04-09-89, developed by the Moscow Design and Technology Bureau of the Tobacco and Tobacco Products Division of the USSR State Agroprom and approved by the Food Industry Department of the USSR State Agroprom on 03.03.89 .

The prototype method includes applying by spraying a flavor on a paper base of a lacquered foil at an air pressure of 0.8-1.2 kg / cm ² . As a flavoring use an alcohol solution of menthol, containing, by weight. menthol 77-81; 96% rectified alcohol 23-19.

 The prototype device comprises a container with a pipeline for supplying flavor, air ducts and a compressor, a spraying means.

The prototype method and device have the following disadvantages: due to the high content of menthol in the flavoring, the pipeline supplying the flavoring to the spraying agent is clogged, since menthol crystallizes, the complexity of preparing a highly concentrated flavoring, high viscosity of the menthol solution leads to uneven application of the flavoring, to large losses when spraying due to the creation of a large volume of an aerosol cloud, resulting in contamination of the working parts of the equipment, air and industrial premises, increased explosion hazard; applying the flavoring in the packaging process on the paper base of the lined foil leads to uneven application of the flavoring on the foil, requires a long tracking of the products (cigarettes) for menthol to penetrate the cigarettes due to diffusion, uncontrolled quality of the cigarettes;
atomization by ejection and under high pressure leads to the formation of a coarse aerosol of flavoring, a large amount of aerosol cloud, uneven application, large losses to the environment, the need for additional equipment to trap menthol vapor, a lot of labor and interruption of the production cycle to clean the equipment from pollution;
the constructive implementation of the device, for example, a container for supplying flavoring, leads to the use of a small volume of flavoring, due to its leakage, the air contaminated with menthol vapors enters the working area, due to the lack of oil separation by the filter, compressor oil can enter the air duct and then onto the finished product; the spraying tool is based on the method of liquid ejection by air flow, the absence of favorable conditions for mixing the compressed air and menthol solution leads to the formation of a coarse aerosol and, as a result, to the unproductive menthol flow, there is no precise adjustment of the application of the flavor solution due to pressure fluctuations in the air duct, and also due to changes in the pressure drop between the container and the spraying means, the unfounded use of the ejection method for such a highly viscous (oversaturation menthol solution) of a liquid; the absence of a receiver for leveling sharp pressure surges between the compressor and the spraying means is also one of the reasons for the uneven application of the flavoring solution.

 All of these shortcomings led to the production of non-standardized finished products, a large unproductive consumption of the flavor, significant contamination of the production facilities and equipment by the flavor.

 In the proposed method for producing flavored cigarettes, comprising preparing and applying by spraying a flavoring, for example, an alcohol solution of menthol, on the material in the manufacture of cigarettes; during the preparation of the flavor, peppermint oil is added to the menthol alcohol solution and the flavor components are mixed, wt.

96% rectified alcohol 80-84
Preliminary
warmed up
to a menthol liquid state 9-11 Peppermint oil 7-9 The flavoring is sprayed directly onto the formed tobacco tow in a vacuum zone in the amount of 7.0-8.0 g per 1 kg of tobacco tow at a flavoring pressure of 0.25-0, 3 kg / cm ² .

 Non-compliance with at least one of the features of the proposed method, subject to all other essential features.

 Greater or less than the interval (84-80 wt.) Rectified alcohol in the composition of the flavor, leads (respectively) to a decrease or increase in the content of menthol and peppermint oil in the finished product, deterioration in the taste of the finished product; to a change in the viscosity of the flavoring liquid and, consequently, to a change in the consumption of menthol and peppermint oil.

 Less than 9 or more than 11 wt. menthol in the flavor leads to a deterioration in the quality of the finished product due to a change in taste.

 Less than 7 or more than 9 wt. peppermint oil in the flavor leads to deterioration in the quality of the finished product due to changes in aromaticity.

 Spraying the flavor directly on the formed tobacco tow in the vacuum zone provides 100% penetration of the flavor into the tobacco layer due to the porosity of the tobacco and vacuum, there is good absorption and retention of the flavor, resulting in low consumption of flavor to obtain the desired taste properties of the finished product, almost complete no loss of flavor.

 When the flavoring consumption per 1 kg of tobacco tow is less than 7.0 g or more than 8.0 g, the taste quality of the products specified by the tasting commission is not provided.

Spraying at a pressure of the flavoring supplied to the atomizer is less than 0.25 kg / cm ² leads to a decrease in flavor consumption, a decrease in the saturation of the finished product with flavor, and therefore to a deterioration in taste, and an increase in pressure above 0.3 kg / cm ² leads to an excessive consumption of the flavor, supersaturation of finished products with flavoring, deterioration of taste.

 To implement the proposed method in a device for producing flavored cigarettes containing a container with a pipeline for supplying flavoring, air ducts and a compressor, spraying means, a container for flavoring is equipped with a sealed lid with an air filter rigidly fixed to it, an air supply regulator, a pressure gauge with a transfer tube, and a safety a valve, a fitting with a calibrated hole with an air duct, an indicator of the flow of flavor into the spraying means, and spraying means Niya is made in the form of a chamber with two fittings for introducing the flavor and compressed air and a calibrated hole for the outlet of the aerosol of the flavor.

 Moreover, the compressor is equipped with a diaphragm, the diameters of the nozzles for introducing the flavor and compressed air into the spraying means and the calibrated holes for the output of the fine aerosol of the flavor are the same.
