    Sterilization of a web of packing material is accomplished in two steps with the web first being coated and washed with a sterilizing agent in liquid form at a first treatment station. The web then passes through a second treatment station where sterilizing liquid is sprayed as a fine mist onto a heated surface which vaporizes the sterilizing liquid. The vapor condenses on the passing web to further sterilize the web. One or more heaters again vaporizes the sterilizing agent which is on the packing web to remove the sterilizing agent. The sterilized packing material web is then cut into individual package units after the web has been filled with sterile contents.

    "one
    The invention relates to the food industry and can be used, for example, in the casting of milk in disposable bags.
    The purpose of the invention is to increase the sterilization efficiency by ensuring the possibility of obtaining steam Oj directly in the chamber formed by the web of packaging material in the manufacture of bags, for example, for milk.
    FIG. 1 schematically shows a device for sterilizing a packaging material web including a packaging machine of a known type; in fig. 2 shows section A-A in FIG. one.
    The device for sterilizing the packaging material web 1 comprises a first processing stage 2, including a guide roller, a container 4 with a liquid sterilizing agent 5, which is a washing unit 6 of a mechanical element 7, a guide wheel 8 located in the upper part of the packaging machine .
    The assembly 6 comprises stationary or movable sponges, scrapers, brushes or the like, which peel off at least one side of the web, which then forms the inside of the package container 5.
    The second processing stage 9 includes a processing chamber 10 located in the upper part of the machine 11 formed by guide rails 12 and a heated element 13. The guide rails 12 have cuffs 14. Under chamber 10 there is a chamber 15 formed by a housing 16 supplied with a sterile syringe air, a means 18 for supplying sterile contents, a heater 19, a forming element 20, a compression element 21, an additional heating element 22, a nozzle element 23 for supplying a liquid sterilizing agent, a heater 24, a diverter 25 jets.
    Under the chamber 15 there are located sealing jaws 26 and means for cutting into separate packages (not yet taken),
    The nozzle element 23 is mounted on the wall of the housing 16 and connected to the line 27 passing outside the treatment chamber 10, and the end of the line 27 through the pump 28 is connected to a container 29 containing a liquid sterilizing agent.


    122
    A cloth 1 of the material is formed into the pipe 30. In the upper part of the chamber of the second stage of processing there is a nozzle 31 for outputting a mixture of sterile air with hydrogen peroxide vapor.
    The operation of the device is as follows.
    Cloth 1 packaging material is continuously fed to the first stage 2 processing. The packaging machine contains a series of guide rollers 3. During the conversion of the packaging material into a tube-shaped form, the web moves mainly vertically downward from the direction of the wheel 8 to the forming element 20. When the web 1 of the packaging material reaches the mold 20 of the element 20 two longitudinal edges of the web several overlap one another. The heater 19, located directly above the forming element 20, heats the thermoplastic layer of the two edges, after which the edges are subjected to joint compression with the aid of the compression element 21 so that it forms 1-1 Longitudinal sealing.
    Above the heater 19 is placed a means 18 for supplying sterile contents to the lower end of the formed pipe 30, which has a seal impermeable to the liquid, while the content level is located above the level at which the double jaw 26 is produced while simultaneously forming the pipe .
     The means 18 for supplying the sterile contents for most of the length is surrounded by the tube 17 for supplying sterile air. I
    The supply tube 17 passes through the pipe VZO, ending at some distance above the jet breaker 25, deflecting the air flow in such a way that it passes upward through the pipe 30. In addition to the sterile air supply pipe 17 and the sterile content supply means 18 there is also a tubular heater 24, which consists of either an electrically heated element placed coaxially around the supply tubes.
    The previously described packaging machine contains elements.
    31
    sterilized packing material webs, which are grouped in two stages 2 and 9 of processing.
    The first processing stage 2 is located at the upper end of the machine and consists of a container 4 for a liquid sterilizing agent 5 and mechanical elements 7 for erasing the liquid sterilizing agent from the sheets. In the lower part of the container there is a protrusion unit 6 containing a directional roller 3 around which the web is stretched to give it a certain position, and a brush, sponge or similar element located below, rotatably mounted and acting On the other side of the web, which then becomes the inner side of the pipe. With the help of guide rollers 3 arranged in the container 4 and in the latter, the web passes down into the container 4 along one wall and then upwards from the bath along the other wall to ontainer. After exiting the container, the web passes through the washing element 7, which is inserted, for example, from rubber scrapers.
    After the web 1 of the packaging material passes the direction of the 0–0; its wheel 8, located at the upper end of the packaging machine, it 1RHODs into contact with the second processing stage 9, which contains its own chamber 15, in which the sterile air supply tube 17 Additional heating unit is placed: element 22, having the form of a horizontally arranged plate, to the top side of which the nozzle element 23 is directed.
    Nozzle 23 is mounted on the wall of the housing of the chamber 15 and connected to a line 27 located outside the chamber and having a container 29 of a liquid sterilizing agent. On line 27 is installed pump 28.
    The upper part of the chamber contains an elongated element 13 that can be heated and provided with two longitudinal guide rails 12 designed to fit tightly with the two longitudinal edges of the web 1 using the cuffs 14. The guide bars 12 fix the position of the web 1 of packaging material as it moves down to the fop syruyush-
    124
    element 20 and at the same time provide high-quality compaction at the edge of the web 1 of the material with the help of the cuff 14. In addition, guide rails are involved in the transformation of the packaging material web as it moves from the wheel 8, where the cross section of the web does not flatten element 20, where the canvas acquires a circular cross section.
    The first step of the treatment is preparatory and serves not only to sc1 the contact of the web with the sterilizing liquid, but also to be vyssa by mechanical cleaning or at least the separation and dispersion of bacteria, the ECIx cod on the web.
    The main processing of the canvas occurs at the second stage. With the help of the web 1, the heating element t3 and the body 16, a closed processing chamber is formed, to which the side of the web of packaging material is directed all the way from top to bottom to form the inner side of the pipe.
    A stream of sterile air enters continuously through the tube 17 into the treatment chamber. Air escapes from the bottom of the pipe 30, is deflected with the help of the jet deflector 25, so that it passes upward between the tubular heater 24 and the inner wall of the pipe 30, and then further upwards through the chamber 15, mine nozzle element 23, and out through the nozzle 31 located in the upper part of the second stage 9. The level of constant supply of sterile air is such that a certain pressure is maintained inside the pipe, ensuring a seal between the cuffs 14 and the edge region of the packaging material. In addition, this pressure level excludes the possibility of ambient air penetrating inside the chamber 15.
    In the course of operation, a liquid sterilizing agent, or hydrogen peroxide, is periodically supplied to the nozzle element 23 by means of a pump 28. The nozzle element 23 is a spray nozzle that finely atomizes the peroxide to a high level of atomization so that the peroxide, when it reaches the additional heated element 22, the appearance of mist or very small droplets. The surface of the additional heated body 22 facing the nozzle element 23 has a temperature of 160-250 ° C. Temperature control ensures that the process proceeds such that the liquid sterilizing agent supplied (for example; hydrogen peroxide) never cools the body surface to a temperature that would be lower evaporation temperature of liquid sterilizing agent} i. each small drop of hydrogen peroxide coming into contact with the surface of the heated body immediately evaporates, which means that a part of the pure re-vapor in the caustic evaporates simultaneously with a part of the water in this drop, therefore a homogeneous mixture of hydrogen peroxide vapor is formed water. Using sterile air, the vapors formed are then directed upwards between the inner side of the Cavity 1 of the material and the body 13, which is heated to a temperature high enough to prevent the vapors from condensing on the surface of the heated body. On the other hand, the packaging material web in most cases has a room temperature, which means that the vapor is condensed by an even-naked layer on the surface of the packaging material web facing the treatment chamber. It is this surface that was previously treated on. first step, Toe, was washed and cleaned by the primary liquid sterilizing agent. As a result, most of the bacteria were removed and the remaining

    a portion of the bacterial layer becomes paBHOMepHouj, as a result of which hydrogen peroxide vapor is easier to reach. each individual bacterium, as they condense not only on the canvas, but also on the caNiHX batters. This allows for a high bactericidal effect. An excess or used hour of peroxide vapor passes along with the hot sterile air further and out through the nozzle 31 ..
    After the passage of the web 1 through the upper part of the chamber 15, hydrogen peroxide vapor is no longer supplied to it, the inner side of the material web now comes into contact with sterile air introduced through the tube 17, which, when passing upward, larps the tubular heater 24, which causes loss of a certain part of condensed hydrogen peroxide. When the web of material has melted down the forming element 20 and reaches the tubular heater 24, it is heated to such an extent that the remaining hydrogen peroxide condensed on the inner side of the web is heated, discharged and passes upwards with the sterile air. The part of the material that penetrates through the tubular heater is already sterilized and can be filled with sterile contents, 1M through the means 18,
    Since only couples are used in this device, the possibility of droplets is eliminated, the danger of an explosion is prevented, when using a mixture of hydrogen peroxide and water as a liquid sterilizing agent.
