    The invention relates to methods for sterilizing packaging machine elements with filling the contents of the packaging material with a filling form through a filling tube with two feeding tubes.
    The aim of the invention is to provide a safe and efficient sterilization process, eliminating the likelihood of reinfection and non-sterility.
    The pre-sterile method of sterilizing the filling device of a packaging machine, including coaxially arranged control rod of the supply and filling tubes, the tubular valve element and the packaging sheath, is that the outlet opening of the filling tube is preliminarily blocked with a connecting element to the safety device and the sterilizing hot water vapor is fed through (cut inside the outer supply channels formed respectively between the control rod and the power supply between the feed and filling tubes, after which the safety device removes and forms a transverse seam at the end of the packaging casing, then sterilizing air is passed through the inner and outer feeding channels to form condensate and overpressure to drain the connecting element from the filling outlet tube and form a transverse seam on the packaging casing to create a packaging container, after which sterilization is carried out by feeding sterilizing steam or oil gaseous working agent through the internal feed channel and the channel,

    formed between the packaging sheath and the filling tube, and output it through the outer feeding channel.
    The connecting element can be disconnected by creating a pressure difference between its two sides, and for processing the internal and external feeding channels and the channel formed between the packaging casing and the filling tube, different working agents are used, the internal and external feeding channels being treated with steam or peroxide. hydrogen.
    FIG. 1 shows a device for converting a packaging film to a tubular casing for producing filled packages with a general view; in fig. 2 - the lower part of the filling tube with a connecting element and a safety device, a section; in fig. 3 shows the node I in FIG. 2; in fig. 4 is a sequence of operations for sterilization according to the proposed method.
    In the implementation of the method can be used different types of packaging machines that convert film or sheet packaging material into packaging containers filled with content.
    The packaging machine 1 is supplied with a film packaging material 2 from a rotating roll 3 installed in the lower rear part of the machine. A packaging material is a material of a known type, for example a tape, consisting of layers of paper, plastic and aluminum foil. Packing material 2 is guided along guide rollers 4 to the upper part of the machine, where it has passed through deflection.
    The driving roller 5 is lowered vertically down along the front of the machine. In the process of moving the packaging material 2 down, its longitudinal edges are gradually bent by the bending elements 6 and the guide rollers 17 and in the lower part of the machine are connected to each other, forming a tubular packaging sheath 8. Then a layer of plastic overlapping packaging material with the help of heating and pressure devices 9 warmed to a softening temperature, compressed and then cooled to form a hermetic longitudinal brew. Thus, the film material is transformed into a packaging casing 8 with a hermetic lower end surrounding the filling tube 10, which is also located vertically. The filling tube 10 with the outer supply channel 119 formed between the tube 10 and the inner tube 12 for supplying the contents therein, passes along with the tube 13 for supplying sterilized air through the upper open end of the packaging envelope 8. The filling tube 10 ends on the distance from the lower sealed end of the packaging casing 8, and the supply pipe 13 has an opening located below the weld 14 of the packaging casing 8, which separates the lower end of the specified casing from its upper open part asti. The sterilized contents are fed into the closed space of the packaging casing through the filling tube 10. The lower end of the packaging casing 8 is successively converted into a separate closed packaging container 15 by means of the brewing jaws 16 reciprocating and similarly moving the forming flaps 17 connected to said jaws . The brewing sponges, located in pairs on either side of the tubular casing, simultaneously compress the casing at specified intervals to form transverse compression zones, in which the sealing casing is sealed by heat and pressure. Forming flaps 17 are also located and work in pairs and give the packaging casing 8 an almost rectangular shape, after sealing and from 396
    A filled packaging container is formed. Passing, if necessary, further processing to shape the containers in a regular parallelepiped, the soft packaging containers are removed using a conveyor (not shown).
    FIG. 2 shows the lower end of the filling tube 10 in a section in which the inner tube 12 is concentrically arranged to feed the contents in a liquid form; the outer feeding channel 11 is intended to deliver contents containing particles or streaks, for example fruit pieces or meat . In addition, at the lower end of the filling tube 10 there is a tubular valve 18 located vertically at the lower end of the feed inner tube 12 by means of a movable control rod 19 arranged vertically, the upper end of which is connected to a driving device, for example, a pneumatic cylinder (not shown ). The tubular valve 18 allows the flow of fluid to freely pass through the feed inner tube 12 and out through the lower end thereof. However, when the valve 18 is in the lower position, it closes the annular opening of the outer supply channel 11, preventing the contents of the „
    In the process of preliminary sterilization of the packaging machine according to the proposed method, a removable connecting element 20, having the form of a cup or tube, is used and attached to the lower end of the filling tube 10 with a receptacle ring 21. The connecting element 20 is located opposite the outlet of the outer supply channel 11 and is fixed in him The connecting element 20 with its lower surface is located opposite the cup-shaped safety device 22, which covers the lower end of the filling tube 10 and is connected to it with a connecting pin. A safety device connected to the pin of the pin with the lower end of the filling tube 10 fixes connecting element 20, which is protected from shearing relative to the output fiber under the action of pressure applied to it from filling.
    The connecting tube 20, like the cup-shaped safety device 22 and the filling tube 10, is made of durable corrosion-resistant material, for example stainless steel. The sterilization method takes about 1 second in a packaging machine that converts the packaging film 2 into fully or partially filled packaging containers 15, as follows.
    Content is fed through the outer fill 10 and inner 12 feed tubes. A uniform flow of liquid contents through the valve 18 is fed through the inner tube 12 and, regardless of the position of the valve member, is poured into the bottom of the tubular packaging form. Through the outer filling tube 10, the contents including, for example, fruit particles are supplied. In winter, larger particles are supplied in portions according to the upward-downward movement of the valve 18, the movement of the tubular shell 8, then produced
    River cut off the packaging containers. In the upper position of the valve 18, the contents freely flow from the outer filling tube 10 through its lower end for a limited period of time necessary to create the packaging container. In order for the particles of the contents not to remain in the transverse brewing seams of the tubular casing, the flow of the contents through the feed tube is interrupted long before such welding takes place, and the valve 18 is located in its lowest position (not shown), at which its front part blocks the outlet of the outer feed channel 11, preventing further release of content. Liquid content, however, may flow unhindered into the packaging container.
    In the process of releasing the packaging containers, the connecting member 20 as well as the safety device 22 are removed from the lower end of the filling tube 10. The connecting element 20 and the cup-shaped safety device 22 are used only for cleaning and
    sterilizing the packaging machine with cleaning and sterilizing agents, for example, hot steam or hydrogen peroxide.
    FIG. Figure 4 shows schematically the various stages of the cleaning and sterilization process (the filling tube 10 is shown in section, and the tubular packaging sheath is shown in phantom lines).
    FIG. 4a schematically shows the lower end of the filling tube 10 and its surrounding tubular packaging 8 upon the completion of the release of the packaging containers. The tubular sheath 8 completely surrounds the filling tube 10, its lower end has a sealed jumper. The end of the shell 8 (part of the packaging shell, located below the jumper)

    the empty outer supply duct 11 and the tube 12 are also empty due to the machine being stopped.
    Before resuming the operation of the packaging machine, it is necessary to efficiently clean and sterilize the filling tube, i.e. the outer supply channel 11 and the tube 12, as well as a portion of the outer surface of the filling tube 10, which may be in contact with the contents, i.e. the part located below the weld seam 14. It must also be sterilized and the part of the inner tubular packaging casing surrounding the filling tube 10 to ensure aseptic processing reliability when resuming the operation of the packaging machine.
    To allow internal cleaning and sterilization of the outer supply channel 11 and the tube 12, the lower seal portion of the tubular packaging casing 8 is removed to provide external access to the end of the filling tube 10. At the lower end of the filling tube 10 a connecting element 20 is installed, which has the shape of a stopper or cup inserted into the outlet of the outer supply channel 11, and held there in the locking position by means of an sealing ring located at the edge of the outlet. To fix the connecting element 20 at the lower end of the filling tube 10, most often, a simple engagement due to the forces of friction is enough; however,

    and spring loaded hooks and other accessories. When the connecting element 20 is in place, at the lower end of the filling tube 10, a cup-shaped safety device 22 is attached mechanically manually connected to the filling pipe W by means of a pin connection 23. The safety device 22, the lower inner surface of which is located opposite the connecting element 20, fixes the latter stationary relative to the outlet of the external supply channel 11, completely blocking it, neutralizing at the same time high internal pressures and from the side of the filling tube 10, and preventing damage to the tubular packaging sheath.
    As a result of using the connecting element 20 in the lower part of the filling tube 10, a narrow passage is formed between the tubes 10 and 12, i.e., the ends of the outlet openings of the two tubes 10 and 12 are connected and isolated from the surrounding tubular packaging casing 8 and the area outside the filling tube 10 As a result, the cleaning and sterilizing substance is passed through tubes 10 and 12 without disturbing the tubular packaging casing and other parts located around it.
    For internal sterilization of the filling tube 10, hot steam is used, which passes downward through the inner tube 12, out through the open valve 18 and, by bending around the edges of the connecting element 20, rises along the coaxial outer feed tube 10 (Fig. 46). This combination of cleaning and sterilization continues until the remnants of the contents are completely removed and the filling tube is heated to a temperature that neutralizes all microbes. The high-pressure steam can penetrate the smallest pores of the filling tube 10. During this process, the connecting element 20 is held in place with the help of a safety device 22 designed to withstand the high vapor pressure in the tube 10.
    Steam from the steam generator connected to the packaging machine is supplied through valves and tubes for feeding the contents to the lower end of the filling

    tubes 10. The vapor circulation ceases at a set time, the feed tubes 10 and 12 are cooled with sterilized condensed water or sterilized cooled air flow circulating for a certain time in the filling tube 10. Then, the outer cup-shaped safety device 22 is manually removed, the tubular packaging shell 8 pull down and brew with the brewing jaws 16 of the packaging machine to form a liquid-tight brewing seam under the lower end of the filling second tube 10 (FIG. 4c).
    When the tubular packaging casing 8 is closed at the lower end, the machine is turned on and produced several (10-15) packaging containers without feeding the contents, and instead of this, condensed sterilized water is supplied to the packaging casing 13 through pipes 10 and 12, as well as through the delivery pipe 13 or sterilized gas (Fig. 4). In this case, the substance passing through the tube 10 pushes the connecting element 20 from the outlet of the tube 10. The connecting element 20 falls into the first packing container 15 together with sterilized air and some condensed or sterilized water (Fig. 4d).
    After the system is freed from condensed air or sterilized water (only sterilized air is packaged in containers), the machine stops again in such a position that the tubular packaging sheath 8 is closed by a transverse sealed weld. Then, the sterilizing agent in the form of gas or vapor is supplied to the lower part of the tubular packaging casing 8 through the inner supply tube 12 and the feeding tube 13. The sterilizing agent leaves the packing casing through the open valve 18 and the outer feeding channel 11. In this case, two sterilizers are simultaneously sterilized tubes 10 and 12, the outer parts of the filling tube 10, the valve 18 and the inner surface of the lower part of the tubular packaging casing 8, separated by a weld seam 14. Sterilizing device 111551239
    The equipment passes through these elements for a certain time, after which the sterilization process is interrupted, the packaging machine is turned on, and the sterilizing substance is supplied through the tubes 10 and 12 in the usual way. This completes the cleaning process with sterilization, the packaging machine can again release aseptic packaging containers, fully or partially filled with sterilized contents.
    The proposed method can be modified depending on various types of packing mania and types of filling tubes. In packaging machines with a non-concentric arrangement of filling tubes, the connecting element may take the form of, for example, cups or shaped tube, and in the case of filling pipes with different number of supply tubes, the connecting element 20 will have a different design with all its functional properties . However, in all cases it should be possible to remove the connecting element without direct access to the tubular packaging sheath, t without manual intervention. The connecting element can be removed due to the pressure difference on both its sides, t pressure in the supply pipes, as well as with the help of a valve element occupying a position that allows us to sew the connecting element from the filling pipe or with the help of any mechanically operating devices.
    The method according to the invention can also be modified by using other flow directions. It is possible, for example, to change the flow direction indicated in FIG. 4b and d arrows, on the reverse, n, etching the movement of the cleaning and sterilizing agent.
    In carrying out the method, various cleaning and sterilizing agents can be used, however, it is necessary that the substances harmful to the packaging material do not come into contact with it and that the packaging material is not adversely affected by the pressure difference.
