    floors, and pipelines 10 and 11 for the supply and removal of cleaning fluid. The valves 3 and 4 are mounted with the possibility of opening in opposite directions, the outer surfaces of the plugs 8 and 9 can be made hemispherical, the tubes 6 and 7 for the supply and removal of steam can have truncated conical nozzles 12 and 13 mounted so that their large bases adjoin to chamber 5. In the tube 9 concentric with a gap can be installed a hollow body 14 with a nozzle 15 for removal of steam, and the valve 4 can be connected to the pipeline for supplying cleaning fluid.
    In addition, adjustment valves 3 and 4 have flexible valves 16 and 17, elastic rings 18 and 19 of circular cross section for contact with the internal surfaces of the valve sockets and rods 20 and 21 connected to electromagnets for driving the plugs 8 and 9 of valves 3 and 4 .
    The device for supplying a sterile liquid product contains a source 22 of steam connected by a pipe 23 to a steam valve 24 communicated with a pipe 6 for supplying steam, mounted on a pipe 7 for removing steam a vapor barrier 25 to block the flow of steam on the side of the main pipeline and the regulator A, wherein the vapor barrier 25 and the vapor valve 24 are mounted with the possibility of their simultaneous triggering. The device can be equipped with an additional steam valve 26 and an oscillating vapor barrier 27 connected via pipe 28 to the vapor barrier 25 so that residual food or steam coming out of the oscillating vapor barrier 27 is retracted to drain 29, the Additional steam valve 26 is fixed to a tube 30 connected to the tube 23 and to the tube 28 transmitting the liquid product. The vapor barrier 25 and the oscillating vapor barrier 27 can be provided with deformable valve membranes 31 made of rubber.
    The device may have a cleaning agent 32 connected to the pipe 11.
    The device works as follows.,
    Regulator A is connected through pipe 1 to the main pipe through which the liquid product comes in a sterile state from the storage tank, and to the filling unit to which the liquid product enters through pipe 10. Each packaging machine
    obtains sterile liquid food directly from regulator A for simultaneous feeding from the main line to all packaging machines.
    Regulator A is positioned so that the opposing control valves 3 and 4 are located at a small distance from each other within their working axes, and tubes 6 and 7 for supplying and discharging steam are perpendicular to this axis.
    The outer surfaces of the plugs 8 and 9 of valves 3 and 4 are hemispherical in shape and have elastic rings 18 and 19 of circular cross section, which ensure the tightness of the connection.
    The shafts of the plugs 8 and 9 are screwed into the heads of the rods 20 and 21, and the latter are driven in reciprocating motion by electromagnets located on the central axis.
    The diameters of the tubes 6 and 7 for supplying and discharging steam are larger in the zones that are connected to the chamber 5. Inside the steam supply tube 6, a hollow body 14 is concentrically mounted with a branch pipe 15 for discharging steam to form a gap between them.
    In the case of overlapping of the tubes 6 and 7 and the pipeline 11 and in the case of the opening of the plugs 8 and 9, the sterile liquid product flows freely from the pipeline 10 to the filling machine.
    If plugs 8 and 9 overlap the valve sockets, and the sterilizing steam enters through the steam supply pipe 6, then it passes through narrow gaps in the plugs 8 and 9 and its speed increases as a result, which ensures the extrusion of the residual product from these spaces to tube 7 for removal of steam and, consequently, increases the cleaning efficiency. In this case, the part of the steam passing between the outer surface of the conical nozzle 12 also ensures that residual products are blown out of the zones. in which stagnation is possible, especially near the base of the plugs, which also increases the cleaning efficiency.
    When the space between the valves 3 and 4 is filled with steam from the tube 6 after blowing out food residues into the tube 7, the valve 3 is isolated from the valve 4 with sterilizing steam, which provides a sterile supply of food. In this case, the valve 3 supplies the sterile product from the pipeline 1 to the pipeline 2.
    The regulator A can be located so that the tubes 6 and 7 are located vertically. This arrangement of the tubes contributes to the fact that the chamber 5 will be completely free from the remnants of the food product.
    Liquid food from the main pipeline through pipelines 1 and 2 is supplied to controller A and through valve 4 through pipe 10 enters the filling machine,
    Next, the steam valve 24 opens and the steam from the vapor source 22 is dropped through the tube 23 into the tube 6 of the regulator A.
    The vapor barrier 25 blocks the flow of steam on the side of the main pipeline, i.e. on the side of the valve 3 connected to the steam outlet pipe 7. The vapor barrier 25 is connected by a tube 28 with an oscillating vapor barrier 27 so that residual food or steam coming out of the vapor barrier 27 passes through a diverting pipe to drain 29. An additional steam valve 26 located on the tube 30 connecting the tube 23 with the tube 28, ensures the supply and cut-off of the steam flow from the tube 23 to the tube 28 with the subsequent formation of a barrier from the sterilizing steam for the regulator A at the moment when the filling machine is operating.
    The valve 4 is connected by a pipe 11 with a cleaning agent 32 for sub-streams of the cleaning liquid.
    Solenoid mechanisms are used to drive the steam valves 24 and 26.
    Membranes 31, made from Jesins and located in zones where the flow path opens and closes, are used so that the vapor barrier 25 and the oscillating vapor barrier 27 can create a barrier of sterilizing steam for regulator A and provide low resistance in the time of passage of the residual amount of liquid food product. In addition, the oscillating vapor barrier 27 is blocked by a control signal, ensuring the formation of an intermittent stream of steam.
    The device shown in FIG. 2 is shown at the moment when the filling machine is operating and the packaging container is being processed. At this point, the supply of cleaning fluid to valve 4 is stopped due to shutting off pipe 11, shutting off steam valve 24, steam barrier 25 and oscillating steam barrier 27. After this, steam valve 26 opens, resulting in sterilizing steam being supplied through pipe 30 from the source The 22 pair enters the tube 28 and further enters the oscillating vapor barrier 27, from where it is led off to the drain 29 via the diverting tube. At this point, the valve plugs 8 and 9 open and the sterilized product passes through regulator A and rub line 10 enters the filling machine. At the same time, the steam treats the back of the steam chamber 24 in order to open and close it and the outer side of the closed part of the flat barrier 25. The steam maintains the high-temperature sterile environment without cooling it. Subsequently, a new portion of high-temperature steam is supplied as a result of the opening and closing of the oscillating vapor barrier 27 at the moment when a sterile product is fed to the filling machine.
