Definitions

  • This invention relates to aseptic packaging methods and apparatus for performing the methods, particularly aseptic packaging of products, for example long-life milk, in cartons.
  • an aseptic packaging system in which an aseptic chamber contains an endless chain conveyor which carries tub-form containers from a container supply station to a station at which the containers interiors are sprayed with sterilizing liquid.
  • the chains carry the containers in an inverted condition along an underneath run along most of which the container interiors are exposed to drying air from perforated pipes. This drying is intended to evaporate away all of the residual sterilizing liquid.
  • the containers are then carried along the upper run of the conveyor past a product filling station, a lidding station and a sealing station to a carton removal station.
  • the perforated pipes can also be used for feeding sterilizing fluid therethrough, for example before the apparatus starts its operations, or in between such operations, for the purposes of cleaning or sterilization, followed by drying with sterile drying air.
  • This latter cleaning or sterilization is of the interior of the chamber and of the items, such as the chains, therein, and is not of the interiors of the containers.
  • United States Patent 3566575 discloses an aseptic packaging machine in which hydrogen peroxide is sprayed into a carton at an aseptic treatment station and evaporated away at a drying station.
  • This system has the disadvantage that, unless the carton is to remain at the drying station for an appreciable length of time, which would obviously slow down the whole machine, the drying is inefficient and results in considerable residue of hydrogen peroxide at the filling station.
  • the container top is protected by an aseptic atmosphere until it has.been filled, sealed and discharged from the machine.
  • the sterile air is supplied from a tube.to a chamber bounded at its underneath by a directional screen which distributes the air over the length and width of the unit.
  • Swiss Patent 197802 discloses the use of bactericidal radiation either in the form of an electron beam or in the form of ultra-violet radiation at an aseptic treatment station occupying only a small part of the length of the container path.
  • an aseptic packaging method comprising introducing containers into an aseptic chamber . of an aseptic packaging machine of elongate form; conveying said containers along a path in said chamber including both an advance leg and a return leg each extending along the machine ; sterilizing the interiors of said containers to render said interiors aseptic, feeding a product into said containers and sealingly closing said containers , all while said containers are on said path ; characterised in that said sterilizing comprises irradiating said interiors with bactericidal radiation over at least a major portion of the length of said advance leg.
  • an aseptic packaging machine of elongate form comprising an aseptic chamber introducing means arranged to introduce containers into said chamber ; conveying means arranged to convey said containers along a path in said chamber including both an advance leg and a return leg each extending along the machine ; sterilizing means arranged to render aseptic the interiors of said containers while said containers are on said path ; feeding means .
  • said sterilizing means comprises bactericidal radiation emitting means extending over a section of said path forming at least a major portion of the length of said advance leg.
  • the sterilization comprises irradiating the interiors with bactericidal radiation over at least a major portion of the advance leg, it is possible to have a relatively high speed of carton conveyance combined with sufficient sterilization of the carton interior.
  • an aseptic packaging method comprising introducing into an aseptic chamber , pre-formed, open-topped cartons ; sterilizing the interiors of the cartons to render said interiors aseptic while the cartons are within the chamber ; feeding a product into the cartons while the cartons are within the chamber ; top-sealing the cartons while the cartons are within the chamber ; and removing the product-containing cartons from the chamber ; characterised in that a stream of aseptic air is passed through said chamber in the direction from the product-feeding location to the carton entry of the chamber during said sterilizing, said feeding, and said top-sealing.
  • aseptic packaging apparatus comprising an aseptic chamber ; introducing and removing means arranged to introduce pre-formed, open-topped cartons into said chamber and to remove product-containing cartons therefrom; sterilizing means arranged to render aseptic the interiors of the open-topped cartons while the cartons are within the chamber ; feeding means . arranged to feed a product into the open-topped cartons while the cartons are within the chamber ; and top-sealing means arranged to seal the tops of the cartons while the cartons are within the chamber , characterised in that means is arranged to pass a stream of aseptic air through said chamber in the direction from said feeding means towards a carton entry of said chamber
  • the machine 1 for carrying out aseptic packaging includes at one end of the machine a conventional device 2 for pre-forming (including bottom-sealing) gable-topped cartons.
  • the open-topped, pre-formed cartons are taken to the other end of the machine through a closed channel 3 by means of a chain system.
  • the channel 3 is bounded by covers 4 individually liftable about hinges to give access to the channel interior.
  • the open-topped cartons are advanced stepwise and in a vertically upright condition by means of conveying chains 5 along a hairpin-shaped path P of which an advance leg extends along the machine towards the device 2 and a return leg extends along the machine 1 back towards its front end.
  • the cartons exit from the channel 3 directly into an aseptic chamber 6 which totally encloses the chains 5 and which is provided with access covers 6"'.
  • the chains 5, which are arranged coextensively one above another, have projecting therefrom outwardly of the path P long lugs 5' which extend beyond guide strips extending along the path P, the cartons being received among and advanced along the path P by the long lugs 5' and being supported at one side by the chains 5 and at the other side by the guide strips.
  • the chains 5 carry the cartons first of all to a top pre-breaking device 7, where the open top of each carton is pre- broken.
  • the cartons are passed beneath high-intensity ultra-violet germicidal lamps 8 which extend over a section of the hairpin-shaped path P which forms at least a major portion, in the present case in fact a major portion, of the length of the advance leg of the path P.
  • This means comprises a nozzle arrangement 7' incorporated in the pre-breaker 7 and serving to spray particularly the inside of the carton with H 2 0 2 .
  • the combined effect on the interiors of the cartons of the ultraviolet radiation and the hydrogen peroxide has a synergistic sterilizing action which is highly germicidal.
  • the chains 5 carry the cartons round through 180° to start the return leg of the path P.
  • the cartons first arrive at a filling device 9 where the cartons are filled with an aseptic product, for example long-life milk, the cartons then proceeding to a top heating device 10 where thermoplastics surfaces of the top of each carton are heated to a tacky condition, and the cartons are then advanced to a top sealing device 11 where the gable tops are sealed.
  • the cartons leave the aseptic chamber 6 at an exit hole 6" therefrom at the front end of the machine.
  • aseptic air is fed from a main sterile air filter to aseptic air inlets 13 and 13' of the chamber 6, in which chamber the aseptic air flows from the inlet 13 relatively smoothly to the front end of the chamber 6, where the aseptic air leaves via an aseptic air outlet 14.
  • the aseptic air act as a scavenging gas removing microbes and hydrogen peroxide from the chamber 6, particularly tending to prevent the microbes and the hydrogen peroxide from being carried up to the filling device 9, but the aseptic air also maintains the interior of the chamber 6 at a pressure slightly above atmospheric and thus discourages the entry of ambient air into the chamber.
  • the top pre-breaker 7 is in two sections 71 and 72 which are carried by a common horizontal support 73 itself carried by two horizontal arms 74 fixed to a vertically reciprocating plunger 75.
  • the section 71 comprises two substantially triangular flaps 76 turnable about respective substantially horizontal parallel pivots 77 by respective oscillatory cranks 78. Betueen.each two advances of the stepwise-advanced cartons, the pre-breaking device 7 is lowered onto the two cartons beneath it, and performs its pre-breaking and simultaneously the H202 is sprayed into the carton immediately beyond the section 72 by the nozzle device 7'.
  • the filling device 9 is particularly designed to prevent microbes obtaining access to the aseptic liquid product being supplied to the chamber 6.
  • the filling device includes a mounting frame 20 which mounts four stainless steel reciprocatory bellows 21 having bottom walls which are reci- procatorily driven by respective reciprocatory plungers 22 and having top flanges fixed to respective lower limbs of T-unions 23.
  • Respective upper limbs of the unions 23 contain respective spring-loaded, non-return, inlet valves which open to allow downward flow through the linbs.
  • the chamber 30 is set at a substantially constant pressure owing to the provision of a pressure-regulated air supply to the chamber 30 via a port 33 in a removable end wall 34 of the device 26.
  • a rod 35 which is fixed at one end to the plate 32.
  • The. rod 35 carries abutment flanges 36 which limit the degree of movement of the vall 32 relative to the wall 34.
  • the rod 35 also carries a pointer 37 which moves over a scale 38 to indicate the position of the wall 32 in the device 26.
  • the filling system is always absolutely full of long-life milk, so that there are no voids or air spaces, which would possibly allow microbes to obtain access to the milk.
  • Another advantage of the present filling system is that all of the internal surface area of the system which in use is in contact with the long-life milk can itself easily be sterilised by simply passing a very hot liquid, chemical cleaning fluid or steam through the filling system, so that all of that internal surface area comes into contact with the very hot liquid, the fluid, or the steam.
  • a carton C is shown being filled from one of the nozzles 25. It will be noted that, in this modified manner of filling, the carton C is in a position inclined to the vertical, so that the milk flowing from the nozzle 25 falls dovn onto an internal face of the carton C which face is inclined to the vertical and is directly below the nozzle 25.
  • the arrangement shown in Figure 10 has the advantage of minimising the production of foam on the top of the milk.
  • the cartons C move along the path P in upright positions, except in the region of the filling device 9, where they are in a tilted condition. It will be appreciated that movement of the carton from its upright condition to its tilted condition and then back to its upright condition can be produced in various ways, particularly by suitable design of the chains 5 and/or the guide'strips for the cartons.
  • the machine 1 also includes automatically controlled means for cleaning the internal surface of the aseptic chamber 6, this means consisting of spray nozzles 41 distributed centrally along the length of the chamber. These nozzles serve to supply a cleaning fluid, e.g. a hot detergent solution or steam, to the interior of the chamber 6 in such a manner that the whole of the interior of the chamber 6 receives the cleaning fluid, which can then be drained off through a drain (not shown).
  • a cleaning fluid e.g. a hot detergent solution or steam
  • the machine 1, particularly the aseptic chamber 6 and the associated machine parts, such as the items 5 to 11, are so designed that the only non-aseptic matter deliberately introduced into the chamber 6 is the preformed cartons C.
  • the entry 3' where the empty cartons enter theaseptic chamber 6 and the exit 6" where the filled cartons leave the aseptic chamber can be sealed off outside the chamber 6 by respective air curtains of aseptic air at higher pressure.
  • air curtains are established by slotted tubes 81 and 82 seen in Figures 4 and 3, respectively.
  • the aseptic air for the curtains is taken from a separate sterile air filter giving higher pressure than the main sterile air filter for the chamber 6 itself.
