Definitions

  • the present invention relates to a method for sterilizing an installation for packaging liquid, pasty or pulverulent, food or pharmaceutical sterile products, installation comprising a tunnel closed at both ends and from the upstream end to the downstream end of this tunnel, a station for heating a thermoplastic strip held laterally by gripping members of a transport mechanism such as endless chains, a thermoforming station for forming containers in the thermoplastic strip, a dispenser-dispenser for sterile product, metering device having at least one row of outlet pipes entering the tunnel, a container sealing and sealing station preferably provided downstream of the tunnel, as well as sterile pressurized gas supply units, opening in several places in the tunnel, the base of which is normally closed by the thermoplastic strip, this process consi stant temporarily closing the base of the tunnel with a heat resistant sheet, in particular of metal such as aluminum, extending from the upstream end of the tunnel to beyond the downstream end of that -this and attached to the thermoplastic strip, the side facing the tunnel ceiling is sterile and protected against pollution, to pass separately
  • the sterilizing fluid cannot circulate in the lower part of the lower end of the dispenser-dispenser opening into the tunnel, it only heats up very slowly, which leads to very long sterilization times, especially as the tunnel and the doser- dispenser must then be cooled to a temperature of the order of 30 to 35 ° C before the operation of dosing and dispensing the sterile product in the sterile containers of the sterile thermoplastic strip can begin.
  • An object of the present invention is to eliminate these drawbacks and to propose a method for sterilizing the tunnel and the dispenser-dispenser which is sufficiently rapid and allows thermal sterilization and forced cooling of the dispenser-dispenser without condensation of the sterilizing fluid in said dispenser. -distributor.
  • the heat-resistant sheet is first placed at the base of the entire tunnel and against the edges of the walls delimiting it, and then said sheet is applied. sealingly against the edge of the outlet pipes of the metering-dispenser at the same time as sealingly being applied against the underside of this heat-resistant sheet at least one row of discharge tubes whose axes coincide with those of the outlet pipes and the upper edges of which are situated opposite the lower edges of the outlet pipes, said heat-resistant sheet is drilled with a hole opposite each assembly of the discharge pipe and outlet pipe, pass a hot sterilizing fluid through the dispenser-dispenser which is discharged through the holes in the heat-resistant sheet and the evacuation pipes while sterile air is circulated through the tunnel and then, if necessary, it is circulated through the metering-distributor and the evacuation tubes, a sterile cooling fluid and finally the row of evacuation tubes is lowered below the level of transport of the thermoformed containers in the thermoplastic strip and said heat-resistant sheet and
  • the present invention also relates to a device for sterilizing a tunnel and a dispenser-dispenser forming part of an installation for packaging sterile liquid, pasty or powdery products from the food or pharmaceutical sector, this installation comprising the upstream end towards the downstream end of the tunnel, a station for heating a thermoplastic strip held laterally by gripping members of a transport mechanism such as endless chains, a thermoforming station for forming containers in the thermoplastic strip, a dispenser-dispenser of sterile product, dispenser having at least one row of outlet tubes entering the tunnel, a station for sealing and sealing the containers, preferably provided downstream of the tunnel, as well as supply units into a sterile gas under pressure, such as sterile air, opening at several places in the tunnel, the base of which is normally closed by the thermoplastic strip so that there is only a very small gap or gap between the sterile upper face of the thermoplastic strip and the lower edge of the side walls of the tunnel also closed at the upstream and downstream ends, or, during the sterilization operation, temporarily closed by a
  • the heat-resistant sheet When it is desired to sterilize all of the elements arranged at least partially in the tunnel, such as the heating box of the heating station, the bell and the punch of the forming station, the metering-dispenser, etc., the heat-resistant sheet is put in place so as to close off the tunnel with the exception of a small passage interval between the lower edge of the side and end walls upstream and downstream of the tunnel and said heat-resistant sheet, and is circulated inside the tunnel through the sterile gas supply units, a sterile gas at overpressure relative to the external atmosphere, such as heated air, for example at 200 ° C.
  • a sterile gas at overpressure relative to the external atmosphere such as heated air, for example at 200 ° C.
  • This sterilization system has the disadvantage of requiring a fairly long sterilization time since, in the region of the outlet pipes of the metering device, it has hitherto been impossible to establish a circulation of superheated steam, which '' water condensates are formed there, the temperature of which is only 100 ° C. and thus the rise in temperature of the outlet pipes is slow and rarely exceeds the plateau of 100 ° C. in a reasonable time.
  • the object of the invention is to eliminate this drawback and to provide a sterilization device which makes it possible to rapidly sterilize the metering-dispenser while the sterilization of the tunnel and the other elements mentioned above is carried out in the usual manner. .
  • a sterilization device associated with the metering-dispenser characterized in that it comprises, on the one hand, below the heat-resistant sheet and of the path of the thermoplastic strip and thermoformed containers and, on the other hand, plumb with the outlet pipes of the metering-dispenser, at least one row of discharge tubes open towards the outlet pipes, and capable of being applied with their ends upper against the lower end of the outlet pipes with interposition of the heat-resistant sheet, the edge of the opening of each discharge tube coaxially surrounding the axis of an outlet pipe and coinciding with the lower opening thereof, as well as at least one row of movable piercing members perpendicular to the plane of the heat-resistant sheet, each of these members being arranged coaxially with the common axis n an outlet tube and a corresponding evacuation tube, and guided either by the outlet tube, or by the evacuation tube in which or which it is likely to retract.
  • An advantage of this device lies in the fact that this sterilization of the metering device takes place while the interior face of the tunnel is sterilized with hot air having for example a temperature of 200 ° C.
  • the evacuation tubes are lowered to a rest position in which their openings are located below the path of the bottoms of the thermoformed containers.
  • the heat-resistant sheet and the thermoplastic strip can therefore be advanced step by step and the packaging phase of the products can begin.
  • an overpressure is maintained in the tunnel relative to the ambient atmosphere, by supplying it with a sterile gas slightly overpressured and which, after the tunnel sterilization phase is found at Room temperature.
  • the small holes drilled in the heat-resistant sheet have a fairly small cross-section, so that after the lowering of the discharge tubes, the quantity of sterile gas escapes through these small holes is not sufficient to remove the low overpressure prevailing inside the tunnel and intended to prevent any flow of polluted gas from the outside to the inside of the tunnel.
  • Figure 1 a part of a known sterile packaging installation comprising a sterile tunnel 1, and from the upstream end to the downstream end thereof, a heating station (not shown), a thermoforming station 2, the bell 3 and the punch 4 of which are provided with sterilization means 5, 6 allowing the circulation of a sterilizing fluid, at least one supply unit 7 with a sterile gas such as sterile air emerging by its mouth 8, in particular in the ceiling of the tunnel 1 and in the bell 3 of the thermoforming station 2, and a sterile product dispenser-dispenser 9, the lower part of which, in particular its outlet tubes 10 enter the tunnel 1.
  • a sterile gas such as sterile air emerging by its mouth 8
  • a sterile product dispenser-dispenser 9 the lower part of which, in particular its outlet tubes 10 enter the tunnel 1.
  • L packaging installation also comprises, preferably downstream of the tunnel, a sealing station (not shown) of the containers filled with products and step-by-step advancement means 11 such as endless chains of the therm band oplastic which, with the exception of a small gap opposite the lower edge 1a of the tunnel 1 completely closes the base of said tunnel.
  • a sealing station not shown
  • step-by-step advancement means 11 such as endless chains of the therm band oplastic which, with the exception of a small gap opposite the lower edge 1a of the tunnel 1 completely closes the base of said tunnel.
  • the base of tunnel 1 is closed with a sheet or 'a section of heat-resistant strip 12, in particular an aluminum foil or other thin metallic sheet, the upstream end of which is attached to the thermoplastic sheet 13, the upper face of which is sterile and protected against pollution by a strip of protection until entering the tunnel 1.
  • a sheet or 'a section of heat-resistant strip 12 in particular an aluminum foil or other thin metallic sheet, the upstream end of which is attached to the thermoplastic sheet 13, the upper face of which is sterile and protected against pollution by a strip of protection until entering the tunnel 1.
  • the metering-dispenser 9 is a known metering unit, either of the type with outlet pipes constituting at the same time the ejection nozzles as described in US Pat. No. 4,165,594, or of the type with outlet pipes provided with ejection nozzles mobile as described by French patent 86 08 138.
  • the sterilization device 14 comprises at least one row of evacuation tubes 15 mounted on a support 16 with which or with respect to which they are vertically movable (see arrows F1 in FIG. 3) between, on the one hand, a high position (FIG. 2) in which they apply sealingly against the lower face of the aluminum sheet 12 and they also apply sealingly the upper face of said sheet 12 against the lower edge of the corresponding outlet pipes 10, and , on the other hand, a low position in which the upper end of the discharge tubes 15 is located below the path of the bottoms of the containers 17 formed in the thermoplastic strip 13 (see FIG. 5).
  • Each discharge tube 15 opens at its lower end into a transverse channel 18 connected to the cover of a closed circuit of a sterilization fluid, a circuit which also comprises means for heating and discharging said fluid as well as means for cooling of said fluid.
  • the opening 19 of the tube 15 is delimited by an annular edge 20 which is located opposite that 21 of the corresponding outlet pipe 10, but which has a slightly greater radial width so as to slightly exceed on either side of the annular edge 21 of said pipe 10.
  • the edge 20 of the discharge tube 15 is provided with a seal 22 protruding slightly upwards from the upper face of said edge 20.
  • the sterilization device 14 further comprises a piercing member 23 capable of piercing in the aluminum sheet 12 when the latter is tightly enclosed between the outlet pipes 10 of the metering-dispenser 9 and the delivery tubes. discharge 15 in the high position, a small hole 24 at the location of each tube 15.
