Definitions

  • the invention relates to a device for sterilizing packaging containers according to the preamble of the main claim.
  • a device of this type known for example from DE-OS 25 09 611
  • a hot air / hydrogen peroxide vapor mixture is blown into a chamber to which the containers to be sterilized, for example cups, are fed.
  • Peroxide condenses on the relatively cold walls of the containers and develops its germicidal effect there.
  • the peroxide deposit is flushed out with hot air. This exhaust air enriched with peroxide and the used hot air-peroxide mixture flowing out of the chamber are led outside through a filter.
  • the known device Apart from the fact that in the known device the hot air-peroxide vapor mixture is not free of peroxide droplets, which are not completely removed after being deposited on the container walls during rinsing, so that they enter into the container come into contact with filled goods, the known device has the disadvantage of high sterilant and hot air consumption. This means a high expenditure of energy and, if the filter is not in order, a great annoyance for the operating personnel in the work area. For these reasons, it is desirable to have a sterilizer that has low sterilant and hot air consumption.
  • the problem discussed in the prior art is solved in a simple manner.
  • the fact that the hot air-sterilizing agent vapor mixture is continuously circulated means that the expenditure of heating energy and sterilizing agent is adapted to the actual consumption.
  • the annoyance of the operating personnel is minimal. Due to the uniform loading of the hot air with evaporated sterilizing agent, the mixture has an optimal preparation without droplets of sterilizing agent.
  • FIG. 1 shows a sterilizing device for cup-like containers in simplified form and partly in section
  • FIG. 2 shows a sterilizing chamber of the device according to FIG. 1 in the loading and unloading position.
  • the sterilizing device for cup-like packaging containers 3 comprises a sterilizing chamber 5, a circulating fan 6, an air heater 7, a preparation device 8 for a hot air / steam sterilizing agent mixture and a storage container 9 for sterilizing agents.
  • the sterilization chamber 5 is essentially formed from a stationary, open-topped vessel part 11 and a cover 12 which can be lifted off.
  • the cover 12 is attached to the piston rod 13 of a pneumatic working cylinder 14 so that it can be raised and lowered.
  • On its underside it has holding clamps 15 for holding a container 3 to be sterilized on an edge 4 protruding from its bottom.
  • the vessel part 11 is composed of a jacket 16 and a base piece 17.
  • a nozzle 20 with an upper outlet opening 21 protrudes from the bottom part 17 into the vessel part 11.
  • the nozzle 20 fills the interior of the container 3 to be sterilized for the most part so that, in the case of a container 3 inserted into the vessel part 11 with the lid 12, between the outside of the Nozzle 20 and the container inner walls remain a uniform, narrow gap.
  • the height of the jacket 16 of the vessel part 11 is dimensioned such that when the lid 12 rests, the container 3 held by the latter at the bottom edge 4 with its open end has a distance from the bottom piece 17 which is adapted to the width of the gap described above.
  • a pipe socket 23 within the nozzle 20, which is also inserted in the base piece 17.
  • the water pipe socket 23 surrounds an inner discharge channel 22 and delimits an annular feed channel 24 together with the inside of the nozzle 20 between the outlet opening 21 the nozzle 20 and the outer end of the pipe socket 23, a double-cone valve body 25 is movable, which closes the outlet opening 21 of the nozzle 20 in its upper position and the pipe socket 23 in its lower position.
  • the valve body 25 is moved up and down by a pneumatic working cylinder 27 via a rod 26.
  • the discharge channel 22 of the pipe socket 23 opens at its lower end into a transverse bore 28 and the feed channel 24 between the pipe socket 23 and the nozzle 20 into a transverse bore 29 in the base piece 17.
  • a ring 30 with an annular groove 31 surrounds the jacket 16 of the vessel part 11. Breakthroughs 32 in the jacket 16 and an opening 33 in the ring 30 connect the interior of the vessel part 11 via the annular groove 31 with a line 35.
  • This line 35 leads via a check valve 36 and a line 37, which with the transverse bore 28 in Bottom piece is connected to the suction side of the circulation fan 6.
  • a line 38 also leads to this suction side via a check valve 39.
  • Set of pressure is connected to the circulation fan 6 via a line 40 of the air heater 7, which has a steam-heated container 41 and a heat exchanger coil 42.
  • the air-guiding heat exchanger coil 42 is connected via a line 43 to the inlet 44 of the treatment device 8. the outlet of which is connected via a line 45 to the transverse bore 29 in the base piece 17.
  • the preparation device 8 which is used to generate the hot air-sterilizing agent vapor mixture used to sterilize the containers 3, is constructed in the manner of an exchange column. It has a cylindrical chamber 48 with a bed 53 of packing, chips or the like, into which a perforated tube 49 projects from above, which is connected via a line 50 and an adjustable throttle valve 51 to the pressurized reservoir 9.
  • the chamber 48 is surrounded by a steam-heated double jacket 52.
  • the line 45 is connected at its upper end.
  • the device described works as follows: In order to process the mixture of hot air and sterilant vapor used for the sterilization of packaging containers 3 in the sterilization chamber 5, the circulation blower 6 promotes partly circulating air from the sterilizing chamber 5 and partly fresh air sucked in via the line 38 and the check valve 39 through the Air heater 7 and the treatment device 8.
  • the hot air heated to about 125 ° C. in the air heater flows in the treatment device 8 from below through the chute tion 53 of the basket 48. It absorbs there through heat-evaporating sterilizing agents, preferably 35% hydrogen peromide, to a value below the saturation limit.
  • the peroxide which is liquid at room temperature is metered by the adjustable pressure built up in the head space of the storage container 9 through the adjustable throttle valve 51 and the pipe 49 and is distributed there.
  • the hot air loaded with peroxide vapor flows through the line 45, the transverse bore 29 and the feed channel 24 in the nozzle 20 in the sterilization chamber 5.
  • the valve body 25 is moved into its upper position, so that it closes the outlet opening 21 of the nozzle 20 and opens the end of the pipe socket 23 (FIG. 2). In this position of the valve body 25, the mixture flows from the inside of the nozzle 20 into the discharge channel 22 of the hrstutzens 23 and through this and the transverse bore 28 and the lines 37 and 38 back to the suction side of the circulation fan 6.
  • the hot air / peroxide vapor mixture is guided in a continuous cycle both during the sterilization phase and in the intermediate phases in which the sterilization chamber 5 is loaded and unloaded.
  • the sterilization chamber 5 forms part of the Main circuit, and in parallel the discharge channel 22 in the pipe socket 23 and the transverse bore 29 of a bypass.
  • the mixture feed into the sterilization chamber 5 After the mixture feed into the sterilization chamber 5 has been shut off, it remains closed for about 3 seconds in order to let the peroxide act. Another option is to open the chamber and let the peroxide deposit continue to work when the package is open. This way the peroxide evaporates more easily. Then the lid 12 with the container 3 is pulled up. During the exposure time, the condensed peroxide begins to evaporate again when the container wall is heated in the sterilization chamber 5 heated during operation. The small amount of peroxide dries completely when the sterilization chamber 5 is opened. Any remaining peroxide residues can then be dried out by blowing in dry hot air.
  • the sterilized, dry container 3 is then fed directly to the filling and closing. These treatments take place in a sterile room in which the sterilization chamber 5 is also arranged.
  • the exemplary embodiment shown and described has only one sterilization chamber 5.
  • a plurality of containers or container parts are sterilized at the same time and which, for this purpose, has a plurality of sterilization chambers fed by a single dish preparation device or a plurality of nozzles in a single sterilization chamber and have switching valves.
  • the openings 32 forming the outlet of the sterilization chamber and the collecting ring 30 are arranged at the lower end of the jacket 16 of the vessel part 11 near the base piece.
  • the package can of course also stand during the sterilization process, i. that is, the sterilization chamber container can be rotated 180 °. Displacers, supply and discharge lines can then be connected to the movable part, as can the side walls of the bell-shaped container.
