    The invention relates to the food industry and can be used in the manufacture of beer and wine. The purpose of the invention is to improve the quality and taste of the drink. FIG. 1 shows a diagram of a device for carrying out the method; in fig. 2 shows a device with several parallel membrane modules used for carrying out the method, a slit. . .. An apparatus for carrying out the method comprises a separation membrane 1, made in the form of a module, having flanges 2 of fill material at the ends. The membrane 1 is housed in the housing 3. The flanges 2 with separating walls 4 and sealing rings 5 hydraulically tightly divide the housing 3 into the first 6 and second 7 chambers. The membrane 1 is made removable to be replaced when the end elements 8 are sealed. 9. The first supply 10 and the first discharge 11. pipelines communicate with the first chamber 6. The second supply 12 and the second discharge 13 pipelines communicate with the chamber 7; The supply lines 10 and 12 are connected to the work only under static pressure by a static unit containing respectively closed reservoirs 14 and 15 for the liquid with supply pipes with wires 16 and 17, overflow pipes 18 and 19 serving to establish a constant level. liquids, pipelines 20 and 21 ,. gas inlets to obtain an air cushion above the liquid level. Gas pressure is controlled by pressure gauges 22 and 23. Inlet lines 10 and 1 are connected to gas lines 24 and 25 through shut-off devices 26 and 27 and have a flow meter 28 and 29 for controlling the temporary flow rate of the beverage to be processed and the dialysate treatment fluid. In order to establish the determined flow rates of liquids, there is a common regulator 30, to which the regulator ZGi 32 and measuring instruments 33 and 34 are connected, which are designed to control and maintain the required pressure between chambers 6 and B of the discharge pipes 11 and 13 are located control valves 35 and 36, associated with controller 37, as well as measuring and regulating devices, respectively, 38 and 39. Both regulators 30 and 37 can either be connected to each other, the libre is a single controller a torus that allows specified fluid flow rates: in chambers 6 and 7, establish pressure over a wide range and at the same time maintain a low pressure drop across the separation membrane. The housing 3 may be provided with a heat insulating shell 40. Heat insulation pipes and / or fittings may be used. The whole device can be installed in a space in which it is kept constant on temperature. To implement the method, a device can be used containing several pairs of membrane modules 1, each of which is placed. In its housing 3, each first inlet pipe 10 and first outlet pipe 11 is connected to a common first inlet pipe 41 and a first outlet pipe 42 and its second inlet 12 and outlet 13 pipe with a common second main inlet a pipe 43 and a second main outlet pipe 44. For regulating and measuring fluid flows, in the case of different flows, passing through each module 1, measuring and control or setting devices are installed in each pipe line 1013 (Fig. 2 not shown) similar to the devices of the device of FIG. 1. A common second main supply pipe 43 and a common second main discharge pipe 44 are connected to a conveying unit (not shown). The method of preparing fermented beverages with reduced alcohol content involves the fermentation of the wort and removal of alcohol from the fermented beverage by passing the fermented drink along the dialysis membrane from one of the booms and the dialysis fluid from the other side with a pressure difference of 10 to 500 kPa. At the same time, water containing extractive substances of the fermented drink, or previously released, is used as a dialysis fluid. 3-. . spawned naprk from alcohol, corresponding to the quality of the dialyzed beverage. It is possible to carry out a method in which the pre-release of the alcohol of the fermented beverage is carried out by adsorption, extraction with reverse osmosis and / or distillation. P r i m e, p 1. To prepare fermented beer with a reduced alcohol content, the brand beer is taken as the starting product. . Pils. After fermenting the wort and removing the alcohol that has been fermented, the wort content is 12%, its alcohol content is 3.91% by weight, and the content of extractives. 3.93% by weight. As a membrane, a dialyzer with a binder of cellulosic hollow filaments is used, which are obtained from honey-g. An intermixed cellulose solution widely used in hemidialysis. The membrane membrane surface is 1.3 m. Water containing the extractive substances of fermented beverage is used as a dialysis fluid . With a change in pressure difference of 10,500 kPa, the alcohol content in the beer is reduced by 30 to 65%, respectively, and finally amounts to 6.5%, which corresponds to non-alcoholic beer. , L p and m r 2. The wine obtained by fermenting the wort is passed along the dialysis membrane j on the other side of which water is passed as dialysis liquid containing the extractive substances of the fermented beverage. The differential pressure is 15 kPa. The alcohol content in VI does not decrease from 80.8 to 56.9 g / l, EXAMPLE 3. Champagne (obtained by fermenting the wort). Successively passed through two dialysis membranes. Champagne is used as the dialysis liquid, from which alcohol is removed by vacuum distillation, diluted to its original volume and saturated with carbon dioxide. The pressure is 470 kPa, the pressure difference is 20 kPa. By dialysis, the alcohol content is reduced from 89.2 to 52.3 g / l. The content of extractives and acids remains unchanged. The taste of champagne obtained corresponds to the original. During dialysis, the metabolism occurs only by diffusion, so that the decisive parameter of the process is the concentration difference on the membrane, and during reverse osmosis, the pressure difference, mainly 0.5 bar. The use of dialysate containing extracts of fermented beverages in concentrations that prevent the passage of beverage extractives allows the use of membranes having a low selective ability. In this case, the dialysate is freed from the alcohol obtained by it. Adsorption, extraction, reverse osmosis and / or distillation are reused. . For beverages containing carbon dioxide, the method is implemented at elevated pressure, with the pressure difference being kept low to avoid ultrafiltration. The pressure at which dialysis takes place sets the pressure to the full extent of the carbon dioxide dissolved in the fermented beverage in order to keep the carbon dioxide still in solution on the membrane surface and prevent gassing. The use of a dialysis fluid containing carbon dioxide in an amount corresponding to its amount in the fermented beverage subject to dialysis. Reduces the alcohol content in the beverage, retaining the carbon dioxide content. A change in the pressure differential between dialysate and a dialysis drink and the use of dialysate with the required content of extractive substances, together with a decrease in the alcohol content, can improve the taste of the drink (wine, beer or champagne) by ultrafiltration. In this case, it is advisable to separate the processes of ultrafiltration and dialysis. The use of several membrane modules allows each of them to be replaced without interrupting the whole process and to reduce the alcohol content in the beverage gradually to a value close to zero. The proposed method allows to improve the quality of v and the taste of the drink.
