Through the device 4 for the injection of gas and the mixing valve 5, 5-20 carbon dioxides of carbon are mixed with air and the resulting oxygen-containing mixture with oxygen content of 0505-0.15 ml / h is fed into 1 g of dry drops. recycled wort B, pipe 10, where its turbulent mode is sent to heat exchanger 6, and then to the fermentation tank 1 o Part of the wort is fed to the device 7 to separate the wort from the drohakey and bring it to an excess of drozhzhey Ostazt: EU shaky relkirkulyut in pipeline 9 of the main recirculated uj-ioHKoro contour 2 Co and 3 Cp.
    The invention relates to the alcohol industry and relates to a method for producing alcohol and an installation for its implementation,.
    The purpose of the invention is to increase the yield of alcohol and the productivity of the plant.
    The drawing is a setup for implementing the Method of
    The plant contains a fermentation tank 1, in the lower part of which a device 2 is placed for bubbling the wort. vertically installed venturi pipe, device 3 for collecting fermentation gases of the bar-type, device 4 for injecting gas with a valve-mixer 5, heat exchanger 6 and device 7 for separating the wort from thrushes
    In the upper part of the fermentation tank 1, a backpressure valve 8 is placed designed to prevent carbon dioxide from entering the tank. A wort containing the fermentation process, connected to the pipeline 9, connects | m fermentation tank 1 with a device 3 for catching fermentation gases and performing the function of mamutra a-suca,
    The fermentation tank K for the fermentation gas trapping device 3, the heat exchanger 6 and the wort bubbling device 2 are connected by pipelines 9-11 to form the main circulation loop with the Additional circulation loop formed by connecting pipe 12, pipeline 13 and pipe 9, , a wort bubbling device 2, a device 7 for separating the wort from the yeast and the upper part of the fermentation tank 1 and serves to recirculate the yeast. The main and additional circulation circuits are connected to the pipeline 14 l supplying fresh wort e
    The brolsenik gas trapping device 3 is indicated by a pipeline 15 for carbon dioxide removal with a gas injection device 4 which is connected via pipeline through valve-mixer 5 to pipeline 10 (The device 7 for separating the wort from the yeast is provided with a pipeline 16). tated wort with valve 17 installed on it and SLIENPSPT shutter 18 to remove possible surplus yeast assets. Pipe 13 has a recirculating valve 19 which allows the wort to be recycled with yeast m in the duct 9 under deist3i
    by the pressure s formed by the height of the pipeline Yu,
    The installation works as follows.
    Fresh wort with the sugar content in us from 100 to 280 g / l knzh-ektiruyut through the wort feed pipeline 14 and pipeline 11 to the fermentation tank through the wort bubbling device 2, in the amount of O, 2-0; 5 the amount of wort in the cycle "In the fermentation tank 1, the wort is contacted with yeast, during the process the wort fermenter is carried out and; the sprinkling of the wort with yeast j forms in the process of gas and; where the coal acid gas 5 is released from the wort, takes the form of bubbles, expands and performs mamutnosos. Due to the high speed of circulation of the wort through line 9, foam is formed, which is crushed and the wort is partially degassed. trapping gas fermentation. Wort subjected to degassing is directed in turbulent mode through pipeline 10, for which it is possible to absorb some pressure loss throughout this pipeline. Pipe 10 dimensions depend bt wort circulation speed5 Turbulence can be affected not only by changing sizes piping, but also in order to install membranes or partitions in the last, it is necessary to ensure that the height of the fermenter
    was sufficient to overcome the
    pressure loss 5 which may exceed the equivalent of 2 m of water column.
    From device 3 for trapping the fermentation gases through the carbon dioxide pipeline 15, carbon is ejected and a part of it is fed through gas injection device 4, mixed by means of a mixing valve 5 with air at a ratio of 5-20 vol, h, carbon dioxide and 1 vol. h air and pipeline 16 supply oxygen-containing mixture to 10 wort in quantity 5 that provides 0505-01515 ml / h oxygen content at atmospheric pressure 3 1 g dry weight of yeast, while the wort is fermented at yeast from 50 to

    100 g of dry substance per liter, the recirculated wort is cooled in the heat exchanger 6 to the temperature of the original wort, the fermentation tank 1 is returned via pipeline 11 r. Part of the wort that has been fermented and contains alcohol is takenJ for which it is sent through device 12 to device 7 to separate the wort from the yeast, where the yeast is decanted at a rate of about 20 cm / min, which makes it possible to obtain a wort cleared of yeast with an alcohol content of 50-80 g / l, which through line 16 through valve 17 removes the cycle and the excess yeast t through the drain Noah 18, the yeast is recirculated through conduit 13 to conduit 9 by means of the pressure S generated by the height of conduit 10, via a recirculating valve 19,
    For carrying out the process, a fermentation tank with a volume of at least 50 in which the wort can slowly rise at a speed of about 1-2 cm / s is used. At the same time the tank is arbitrarily divided into three zones: bubbling of sedimentation and concentration of carbon dioxide, the fresh wort is mixed with recirculated wort and the wort in the lower part of the tank, in the sedimentation zone, contactionronac1-: e wort from the yeast occurs, and in the carbon dioxide concentration zone, as in the entire volume of the tank carbon in the form of gas bubbles, is retained by the counterpressure generated in the upper part of the tank
    In carrying out the method, the yeast Saccharomyces cerevisiae with a good flocculation ability is used.
    Example 1, Into the bottom of the fermentation tank, 60 m per hour of fresh wort containing 100 g / l of fermentable sugar are injected, the content of active yeast in the wort is 50 g of dry matter per

    during fermentation, the gases are separated from the recirculated wort, an oxygen-containing mixture is introduced into it in an amount that provides an oxygen content of 0.05 ml / h at atmospheric pressure from 1 g dry weight of the yeast. The mixture is obtained by mixing 1 air with 5 vol. h. carbon dioxide The recycled wort 6 is cooled to the fermentation temperature and returned to the lower part of the 51) single chiller, where the wort is bubbled by injecting an upward flow of the circulating wort in the “turbulence mode” is such that puffed gas has a diameter not exceeding 3.5 mm
    From the part of the wort after cooling the alcohol containing 8.5% by volume, the yeast is separated and removed from the cycle in the same way as excess yeast and the remaining yeast is recycled to the recirculation wort 5 A fresh wort is injected per hour in the amount of the wort, in cycle
    Example 2 The method is carried out analogously to example 1j only fresh wort is injected in an amount of 0.5 of the amount of wort in the cycle, with a sugar content of 280 g / l 5 in it, the content of yeast in the fermented wort is 100 g of dry matter per liter.
