Abstract

The invention relates to the wine industry. The purpose of the invention is to improve the quality of the finished product due to a more complete enrichment of valuable impurities and a reduction in heat and energy consumption. The method is as follows. The wine material is heated to 110 ° C and kept at this temperature for the formation of volatile enanthic impurities. A stream of aged wine is passed through a special container and when the temperature decreases from 110 to 95 ° C and a pressure of 200 to 103-123 kPa, the fraction enriched with enanthic ether is separated by self-evaporation, which is divided into two streams. One of them is introduced into the finished product, and the other is returned to the original wine material. In the process of distillation, low-boiling impurities, main stream and furfural are separated, which are also introduced into the final product. Before distillation, carbon dioxide is extracted from the wine material. 1 tab., 1 Il.

Description

The invention relates to the wine industry.

The purpose of the invention is to improve the quality of the finished product due to a more complete enrichment of valuable impurities and reduction of heat and energy costs.

The drawing shows a scheme for carrying out the proposed method.

The scheme contains a reflux condenser 1, a distillation column 2, a separator 3, a condenser 4, a heater-heater 5, a holder 6, a tank 7, a condenser 8. a boiler 9, a condenser 10, a alcohol trap 11,

a selection comb 12, a refrigerator 13, a condenser 14 and a refrigerator 15. Distillation column 2 consists of boiled 16 and concentration 1 / parts,

The winematerial heated in the reflux condenser 1 to 75 ° C with alcohol vapors leaving the column 2 enters the separator 3, where the release of CO других and other products occurs; Those that adversely affect the quality of volatile impurities that are removed from the system through the condenser 4. From the separator 3, the winemaker enters the preheater-booster 5, warms it to a temperature of 105-110 ° C and then goes to the control unit B1. From the moment the wine arrives in wine holder 6 until it leaves it, it takes 8-10 hours, i.e. the time required for the passage of new processes of formation of volatile substances. In order to activate beneficial horse alcohol and fatty acid binding, the holder is filled with .20 mm copper rings. From the holder 6, the wine is supplied to the container 7, where due to self-evaporation: when the temperature decreases from 110 to 95-100 ° C and pressure from 200 to 103-- 123 k11a, volatile substances of enant ether enter condenser 8, in which two streams in the ratio of 1: 3; Most of the stream is sent to the concentration part 17 of column 2 below the selection of horse alcohol, and a smaller part goes to the finished product for its enrichment with useful impurities (enanthic ether). The wine material from the grinder is supplied to the feed plate of the distillation column 2. Column 2 consists of boiled 16 and concentration 17 parts and is heated through a boiler 9. Alcoholic vapors, a passage, a concentration part 17 of a column 2, enter a reflux condenser 1, give off heat to preheat the wine material and reflux in column 2, uncondensed alcohol vapors with volatile impurities, they enter the condenser 10 and further into the alcohol trap 11, from which the head fraction is removed from the system. From the concentration part 17 of the column 2 of the extraction comb 12, the output of 65% by volume of alcohol is produced through a refrigerator 13. The selection alcohol selection comb is positioned so as to remove horse alcohol enriched with useful impurities from zones of varying alcohol concentration. (furfural) is carried out from the zone of their concentration from the lower plates of the column 2, where the alcohol concentration is 5-15% by volume, to the condenser 14, and from there to the final product for enrichment.

tripping below the feed inlet, directed to refrigerator 15, and then removed from the system.

In the example, the process of producing horse alcohol is carried out in a continuous stream while passing at a rate of 140 dal / h. The wine material is heated to 75 ° C, carbon dioxide extracted from it is separated, heated to 110 ° C and maintained. The temperature in the support 6 is maintained at 110 ° C due to the supply of heat to the boiler 5. The pressure in the support is provided with a wine pillar height of 10 m, which corresponds to a pressure of 200 kNa. The flow of wine due to the difference in height between the level of wine in the apparatus and tank 7, flows by gravity to the last, where the pressure drops from 200 to 103 kPa (atmospheric) and temperatures fall from 110 to 95 ° C. With these parameters, enanthic ether is self-evaporated, which is separated into condenser 8, from where it is divided into two streams in a ratio of -1: 3. One stream (0.8 dal / h) is directed to the enrichment of finished horse alcohol, and the other (2.4 dal / h) is returned to the distillation column 2. The separated aqueous-alcoholic steam with volatile impurities from column 2 enters the reflux condenser. 1, condenses therein and returns as reflux to the top plate of column 2. Uncondensed part of the water-alcohol liquid from the reflux condenser 1 enters the condenser 10, and from it into the alcohol tray 11, the condensate is returned to the top plate of the column 2. From the trap 11 head fraction in the amount of 0.5% or 0.22 dal / h con entratsiey 90 vol.% is withdrawn from the system.

Horse alcohol from the distillation column 2 from the comb 12 of sampling in the amount of 63.2 dal / h at a concentration of 65% „% goes into the refrigerator 13, and from there into the collection of the finished product (not shown).

Tail impurities with fusel oil components are removed from the concentration zone of column 2 in the amount of 4.1 dal / h at a concentration of 30% by volume in the fusel oil cooler 15, and from it into the collection (not shown).

From the bottom of column 2, the fraction containing furfural in the amount of 0.21 dal / h is transferred to condenser 14, and then to the collection of horse alcohol for its enrichment.

All experiments on the preparation of horse alcohol with different modes and parameters are listed in the table. I

As can be seen from the table, the accepted modes are optimal. A temperature of 110 ° C is generally accepted in the technology of horse production for the formation of impurities that are valuable for horse alcohol. Its reduction to 95 ° C is due to the process conditions at a certain pressure, since this temperature corresponds to the atmospheric pressure at which the wine material boils and the enanthic ether is self-evaporated. At a temperature outside the range of, for example, 93-94 ° C, no enanthic ether is boiling and precipitating. It is not necessary to create a temperature above 110 ° C, since all of the neoplasms occur in it.

The proposed method makes it possible to improve the quality of the finished product due to a more complete enrichment of valuable impurities and to reduce heat and energy consumption.
