The invention relates to a technology of obtaining alcoholic beverages, namely, vodka.

Analysis of patterns of consumption of these products shows that the requirements for production technologies vodkas and their quality is constantly increasing. Simultaneously with the issue of removal of various kinds of natural impurities, in particular of fusel oils and methyl alcohol, there is another problem - conservation and improvement of specific vodka flavor, improve and provide new organoleptic characteristics. This leads to the necessity of finding and using original technologies with high performance materials.

A method of obtaining alcoholic beverages, including vodka, U.S. patent No. 6846503 (publ. 2005), which extract water-alcohol mixture in wooden barrels for 1 year. During this long period elapses adsorption, in which the porous structure of the wood absorbs impurities that degrade the taste of the beverage, and enriches the taste of natural ingredients. However, this method is ineffective due to insufficient adsorption characteristics of the tree too long and more acceptable for the receipt and processing of other types of alcoholic drinks.

A method of obtaining vodka high quality on the avce on the invention of U.S. No. 20050058746 (publ. 2005), including the machining stage reverse osmosis system. This method allows to remove from its impurities, reducing its quality and taste, such as acetaldehyde, methyl alcohol, and some others. However, this type of treatment leads to too high purity vodka, degrades its organoleptic characteristics, as vodka should contain the minimum number of impurities, the complete removal of which impoverishes its taste. This method is more applicable for water treatment, part of the vodka.

Known methods for cleaning liquids from organic impurities using as catalysts of noble metals deposited on granular porous media, in particular activated charcoal (patent of the USSR 1797496 (publ. 1993), the patents of the Russian Federation 2240986 (publ. 2004), 2258693 (publ. 2005)). A common shortcoming of these technical solutions is the lack of specific process parameters that determine the applicability of these solutions for use in the food industry.

The closest technical solution to the claimed method is "Silver filtration", designed for the processing of vodka and vodka sorting, RF patent No. 2222586 (publ. 2004). This method consists of passing the vodka through a fixed layer in the active took silver at ostergade charcoal with a silver content of from 0.05 to 4.0% in pulsating turbulent regime with speed 6-30 gave/h per 1 kg of coal. However, the assessment of individual experts vodka, obtained in accordance with the method of the prototype does not have a sufficiently high organoleptic characteristics.

The essence of the invention is as follows.

Technical problem on which this invention is directed, is the development and structure selective and mild catalyst, capable of improving the processing technology of vodka and regulate its consumer properties, as well as the development of the technology application of this catalyst in the food industry.

The technical result of the invention is to increase the degree of purification obtained vodka from toxic impurities: a decline in the content of sulphates, iron, methyl alcohol, 2-propanol, the achievement of contents and ratios of trace contaminants, in which the received number are not toxic, in particular traces of ethylformate, ethyl acetate and acetal, which leads to an increase of the tasting score vodka, significantly improving the performance of the process and its cheaper.

This technical result in the implementation of the invention is achieved by the fact that the vodka passes through a fixed bed of active charcoal granular coal with a grain size of 0.4-6.5 mm, mass impregnated PLA is in the amount of 0.001 to 0.1%, located between the protective and support cylinders, provided with a through-hole of the cartridge filter with end caps, with the rate of passage of vodka through the layer of active charcoal is 30-150 gave/h per 1 kg of coal. In the particular case of the invention processed vodka previously obtained by processing sorting in pulsating turbulent regime over the stationary layer of active charcoal, the mass impregnated silver in a quantity of 0.05 to 4.0 wt.%, with the speed 6-30 gave/h per 1 kg of coal. The best results of the invention can be achieved by the use as an active charcoal coconut charcoal.

It is known that the contact of the aqueous-alcohol solution with active charcoal occur at the same time the adsorption processes of the absorption of impurities contained in the solution, and the oxidation of alcohols and impurities with the formation of aldehydes and other compounds, a small amount which gives the drink a specific "vodka" flavor (Vmmain, Avetisov, Vinblastin. Active carbons Russia. M.: metallurgy, 2000, s-112), while oxidation of the surface coal adversely affect the cleaning performance. The introduction of the coal (impregnation in weight) of metals such as silver and platinum catalyzes the oxidation processes.

the technical task of creating new varieties of vodka was solved through the development and structure of sorption-filtering material in the form of selective and mild catalyst, able to improve the technology of purification of vodka and regulate its consumer properties, as well as technology, providing necessary and sufficient interaction with the specified catalyst. Experimentally were found optimum speed the processing vodka through a layer of active charcoal granular carbon, the size of its granules, the amount of platinum impregnated into the mass of coal, in particular cases of implementation of the invention, the type of active charcoal, which generally allows you to balance the processes of adsorption, oxidation, catalysis and trace enrichment of new substances and thereby to achieve a new harmonious and original taste of vodka platinum filtering.

The processing method of vodka platinum filtering" is as follows.

Obtained by any known method vodka is sent for additional processing by interacting with active charcoal granular carbon (in the particular case of the method - coconut charcoal) with grain sizes of 0.4-6.5 mm, mass impregnated platinum in the amount of 0.001-0.1 wt.% with the speed of vodka through a layer of the specified coal 30-150 gave/h per 1 kg of coal, with the specified coal is located between the protective and support cylinders, provided with a through-hole p is the throne of the filter with end caps. In the particular case of the invention vodka pre-receive technology "Silver filtration", letting the water-alcohol mixture (sorting) in pulsating turbulent regime over the stationary layer of active charcoal granular carbon, in weight which is impregnated silver in a quantity of 0.05 to 4.0 wt.%, with the speed 6-30 gave/h per 1 kg of coal. Additional preliminary stage is performed with the use of the cartridge filter, consisting of a protective and supporting cylinder which has a through-hole, and the end caps.

Obtained in accordance with the claimed method "platinum filtering vodka has a sharp alcohol smell, while maintaining specific "vodka" flavor, has a milder taste due to the presence of traces of new aromatic substances in its composition.

For carrying out the invention can be used following active charcoal: in particular, the brand 607 (producer - company Sutkliffe Speakman - UK), birch wood charcoal domestic production BAU-a, carbonized coconut shell AU FAC, carbonised seed fruits AU Mex, active carbon based on coconut shell Aquasorb CS (producer - company Jacobi), active carbon based on coconut shell brand 607 (producer - Fi is mA Chemivron Carbon Company).

Active charcoal, a lot of which is impregnated platinum in a quantity of 0.001 to 0.1%, was obtained by impregnation of the active charcoal in an aqueous solution of inorganic salts of platinum calculated concentration with subsequent processing in high-temperature regime (800°C) followed by washing.

Evaluation and evidence of the advantages of the claimed invention is based on measuring and comparing the content of sulphates, iron, methyl alcohol is processed in the vodka, and the emergence of new trace, namely: ethylformate, ethyl acetate and acetal. Parameters were estimated by gas chromatography analysis and capillary electrophoresis. Additionally, the assessment of organoleptic characteristics on tasting technique research Institute of food biotechnology RAAS, Moscow (on a ten-point system).
