Abstract

FIELD: alcoholic beverage industry. SUBSTANCE: aqueous-alcoholic mixture for vodka is prepared on base of rectified alcohol of the highest purification. Aqueous-alcoholic mixture is filtered on carbon column filled up with fresh carbon. Vodka skimming is carried out after particular time after filling in of carbon. As soon as particular quantity of aqueous-alcoholic mixture is passed through carbon column vodka skimming is stopped, and fresh carbon is filled up in carbon column. Water of 0.1-0.2 mg equi/cu.dm hardness is used for preparation of alcoholic mixture. It is carried out aeration and cleaning on filters. EFFECT: reduced cost price with simultaneous preservation of all organoleptical properties.

Description

 The invention relates to alcoholic beverage production.

 A known method of preparing vodka (RF patent N 2059707 with priority from 02.26.93, MKI C 12 G 3/08), in which to obtain vodka use the sorting obtained on the basis of rectified ethyl alcohol or rectified ethyl alcohol of higher purification and drinking water, while the sorting is cleaned with a sorbent brand SGN-30A, sorting is passed through a charcoal column and a sand filter, the sorbent is cleaned after passing through sorting through a charcoal column and the strength is adjusted after passing through sand filter.

 The need to use a sorbent along with the use of charcoal and sand filters makes the production of such vodka more expensive.

 Various types of special vodkas are known: special vodka "Anisovaya" (RF patent N 2025511 with priority from 09/29/92), special vodka "Oryol royal" (RF patent N 2016893 with priority from 4.03.93), the disadvantage of which is the need to use them production of expensive raw materials (aromatic alcohols of anise fruits, coriander, aromatic alcohol of lemon oil and sugar syrup for vodka special "Anisova", aromatic alcohol of flowers and linden bark, aromatic alcohol of anise fruits and natural honey for vodka special "Orlovskaya Tsar").

Special vodka is known (see Alcoholic and non-alcoholic drinks. M: Publishing house of standards, 1994, p. 41-44) from a 40 ^o alcohol-water mixture obtained from Extra alcohol, characterized by the following physicochemical parameters: the volume of hydrochloric acid with (HCl) = 0.1 mol / dm ³ spent on titration of 100 cm ^{3 of} vodka, 3.0 - not more; mass concentration of aldehydes in terms of acetic in 1 dm ³ anhydrous alcohol, not more than 3 mg; mass concentration of fusel oil in terms of a mixture of isoamyl and isobutyl alcohols (3: 1) in 1 dm ^{3 of} anhydrous alcohol, not more than 3 mg; mass concentration of esters in terms of ethyl acetate in 1 dm ^{3 of} anhydrous alcohol not more than 25 mg; the volume fraction of methyl alcohol in terms of anhydrous alcohol is not more than 0.03%.

 The disadvantage of this vodka is the use of expensive Extra alcohol for its production, which increases the cost of vodka.

 The problem to which this invention is directed is to reduce the cost of production while maintaining the organoleptic properties of special vodkas and expanding the range of vodkas.

 The problem is solved in that the highest purity alcohol is used for the production of Russian special vodka, while the achievement of physico-chemical indicators characterizing, in accordance with GOST standards, the belonging of Russian special vodka to special vodkas is achieved through the technology of its manufacture.

For the preparation of vodka, water is used from the city water pipe and artesian well, with a hardness of 6.0 - 9.0 mg • equiv / dm ³ , with an iron content of 3.6 - 4.8 mg / dm ³ and a high content of other elements. Therefore, water is deeply purified.

 Initial water is first supplied to three series-connected quartz filters, of which to a filter loaded with magnetite quartzite (for deferrization), after undergoing aeration (mixing with air). Then it is fed to a filter loaded with activated carbon, then to a Na-cation filter and to a reverse osmosis unit.

As a result, the hardness of the purified water becomes 0.1 - 0.2 mg • equiv / dm ³ .

For the production of “Russian special” vodka in a vat, a water-alcohol mixture with a strength of 40 ^o is prepared from rectified higher purification alcohol and softened water according to GOST 2874. The resulting sorting is fed to a pressure vat, from which it flows by gravity into the first filter filled with quartz sand . When applying the sorting from the pressure tank to the first filter, the rotameter measures its flow rate. To adjust the speed at the inlet of the first filter, a valve is installed, made with the possibility of manual adjustment. From the output of the first filter, sorting, cleaned of mechanical impurities, enters the second filter. The second filter is made in the form of a vertically arranged column with a height of about four meters, filled with birch activated carbon (GOST 6217), while the amount of coal and the diameter of the column are selected based on ensuring the most efficient filtration. The speed of passage of the water-alcohol mixture through the second (carbon) filter determines the quality of the cleaning mixture, the highest quality is achieved at a speed of 40 decaliters per hour.

 After the second (coal) filter, the purified sorting is fed to the third filter, as well as the first filled with quartz sand, for cleaning from mechanical impurities.

 Then, the resulting water-alcohol mixture is fed to a finishing vat or collection vat, where it is selected for monitoring to determine whether its physical and chemical properties correspond to the physical and chemical characteristics of Russian Special Vodka (see below).

 At the same time, vodka is taken from the “Russian special” vodka vat after about 40 thousand decalitres of water-alcohol mixture passes through it from the moment the second filter is filled with birch activated carbon.

 Coal from the second filter is taken twice a month to determine its activity by adsorption of acetic acid. In the event that the activity of coal is below 15 units, the coal must be regenerated. After regeneration, activated carbon is not used for the production of "Russian special" vodka.

 If the coal activity is in accordance with the norm, and the physicochemical parameters of the finished vodka in the finishing vat do not correspond to the physicochemical parameters of Russian special vodka, then the selection of vodka from the vat is stopped and checked for compliance with the requirements of GOST 5962 (for alcohol) and 2874 (for water) indicators of water and alcohol supplied to the vat in which the sorting is being prepared.

Through the use of this technology, ethyl special vodka from ethyl rectified higher purification is used to produce “Russian special” vodka, with the following physical and chemical parameters: fortress - 40 ^o ; the volume of hydrochloric acid with (HCl) = 01 mol / dm ³ spent on titration of 100 cm ^{3 of} vodka, not more than 2.0; mass concentration of aldehydes in terms of acetic in 1 dm ³ anhydrous alcohol not more than 4.0 mg; mass concentration of fusel oil in terms of ethyl acetate in 1 dm ^{3 of} anhydrous alcohol, not more than 25.0 mg; the volume fraction of methyl alcohol in terms of anhydrous alcohol is not more than 0.03.

 Organoleptic characteristics of "Russian special" vodka: appearance - a clear liquid; color is colorless; the taste is soft; aroma - vodka.
