Definitions

  • the invention relates to a device and a method for sterilizing glass containers.
  • the packaging is made using complex processes, e.g. Treat with hydrogen peroxide, sterilized with superheated steam / hot air and / or UV light or gamma rays.
  • Treatment with hydrogen peroxide or UV radiation is preferably used for non-heat-resistant plastics, while treatment with superheated steam or hot air is suitable for laminated papers and heat-resistant packaging.
  • a disadvantage of the above-mentioned processes is that the equipment required is complex and the vapors and gases that are produced can be harmful to health, so that suction and possibly glass cleaning are required.
  • the invention has for its object to provide a simple and safe device for sterilizing glass containers, which avoids the disadvantages of the known sterilization process and allows a simple process.
  • the inner surface to be sterilized is flamed with a burner which has a burner head arranged on a burner neck and immersed in the glass container.
  • the burner head is provided with burner outlet openings arranged radially on its end face in the axial direction and on its peripheral surface.
  • the burner can also be provided with a mixing insert to even out the gas flow.
  • the flaming can be carried out without difficulty with glass containers, since these are sufficiently heat-resistant. It can also be carried out in a continuous process; it is safe due to the high flame temperature despite the high throughput speed and causes an absolutely sterile container surface. When the glass container is flamed, there are no harmful gases or vapors if the burners are set so that complete combustion is guaranteed. Finally, the apparatus structure of a plant operating according to the method according to the invention is also very simple, so that overall there are low investment and operating costs.
  • the temperature control during flaming should be selected so that the glass as such reaches at least 250 ° C on the outer surface, while the inner surface, which is important for sterilization, is heated to at least 300 ° C.
  • the burner head can be connected with a burner neck of smaller diameter, preferably with a mixing insert.
  • the mixing insert is used to generate a uniform gas flow through the burner and to ensure an intensive mixing of the fuel gas and the combustion air.
  • the mixing insert preferably consists of several sieves arranged one behind the other with mesh sizes below 1 mm.
  • a perforated plate with a hole diameter of approximately 2 mm and a sieve fabric with a mesh size of approximately 0.5 mm can be arranged in the burner head. This perforated plate with the screen mesh ensures that the gas flow is mixed again and evenly.
  • the diameter of the burner outlet openings on the end face preferably decrease from the outside inwards from approximately 2 mm to 1.5 mm, while the diameter on the peripheral surface is approximately 3 mm. In this way, there are quietly burning flames on the burner head, all of which have approximately the same length.
  • Screen fabrics can also be arranged in front of the burner outlet openings.
  • a support tube with a fuel gas and compressed air connection can be mounted in the burner neck by means of an axial bearing to the burner head and a sealing bearing ring at the other end.
  • a disk-shaped heat shield and / or a rotary drive for example a V-belt pulley, can also be arranged on the burner neck.
  • a controllable burner of the type described above can be used, the flame of which according to the invention is short when entering the glass container and is extended after the burner openings have passed the burner mouth. In this way, the heat radiation from the burner flame can be reduced if the container mouth is already provided with an adhesion promoter and / or an adhesive layer before sterilization.
  • the container mouth can also preferably be cooled with the aid of a gaseous cooling medium, for example sterile air, while the burner is retracted.
  • a gaseous cooling medium for example sterile air
  • the container rim is shielded against the flame, for example with the aid of a cylindrical radiation protection ring, at least during the insertion of the burner.
  • Glass containers 1 are located on a conveyor belt 2 passing through a heating channel 3 and were separated by means of a device (not shown).
  • the glass containers 1 are transported in cycles through the heating channel 3 by means of the conveyor belt 2.
  • Lateral burners 4 for flaming the outer surface of the container are arranged in the heating channel.
  • the containers 1 are lifted off the conveyor belt 2 by means of a lifting device 5.
  • the burners 6 are immersed in cycles in the glass container so that the burner flame spreads over the entire inner surface and is sterilized.
  • the residence time of the glass container 1 in the heating channel 3 and that of the burner 6 in the hollow glass container 1 is set so that a glass outer surface temperature of at least 250 0 C and an inner surface temperature of at least 300 ° C is reached. In this way, the container surface is sterilized with certainty.
  • Each burner 6 preferably consists of a burner neck 8 with an enlarged burner head 9 arranged at the lower end.
  • a support tube 10 is rotatably mounted in the burner neck 8, which is passed through an axial ball bearing 11 in the area of the burner head 9 and at the opposite end of the burner neck 8 a sealing bearing ring 12 is guided.
  • a cylindrical coil spring 14 is arranged between the bearing ring 12 and the flange-shaped hose screw connection 13.
  • the burner is driven via a V-belt pulley 15, which at the same time serves to hold a disk-shaped heat shield 16 fastened by means of a retaining ring 17.
  • a mixing insert 18 comprising a larger number of sieves arranged one behind the other with mesh sizes of less than 1 mm is arranged in the support tube 10.
  • this mixing insert 18 the gas-air mixture supplied is braked and mixed intimately in order to achieve a uniform flame both in the direction of the bottom and on the inner wall of the glass container to reach. The flame should burn quietly and quietly.
  • a perforated plate 19 with hole diameters of approximately 2 mm is additionally arranged in the burner head 9. Below this is a sieve fabric 20 with a mesh size of approximately 0.5 mm. The task of the perforated plate 19 and the wire mesh 20 is to effect an optimal mixing.
  • the end of the burner head 9 is provided with outlet openings 21 which are arranged radially on the end face in the axial direction and on the circumferential surface. On the end face, the hole diameter of the outlet openings 21 decreases from about 2 mm to about 1.5 mm from the outside inwards, while the hole diameter on the circumferential surface is about 3 mm. Screen fabrics 22 are also arranged in this area of the burner head 9.
  • the internal surface of the burner 6 is briefly heated to over 300 ° C. with a dwell time of 1 to 1.5 seconds.
  • the temperature in the heating channel is determined by both the side burner 4 and the vertical burner 6 and can be set so that the required container temperature of at least 250 ° C and extensive sterilization of the outer surface of the glass container is achieved at about 300 ° C. .
