  • the invention relates to an apparatus for controlling the atmosphere of the sterile chamber in an aseptic packaging machine, of the kind in which packaging material in web form is first brought in contact with a chemically acting sterilising liquid and subsequently led through the interior of a sterile chamber inside which the packaging material is freed from liquid residues, and in which the packaging material is formed into a flexible tube and subdivided into individual, filled packages.
  • the apparatus according to theinvention is characterised in that the interior of the sterile chamber forms part of a flow circuit in'which the mixture of chamber air and sterilising agent vapor forming the chamber atmosphere can be circulated with the aid ofa conveying means, in that further throttle means are provided between the chamber and conveying means for generating above-ambient pressure in the sterile chamber and in that the circuit has means for limiting the concentration of the chemical sterilising agent in the atmosphere filling the sterile chamber.
  • a limitation of the concentrationof the chemical sterilising agent in the sterile chamber atmosphere in the sense of the invention makes it possible, by limiting the concentration to less than the dew point concentration, to prevent the formation of condensates that may otherwise enter the packages together with the contents to be packaged and have a harmful effect on the contents. Furthermore, explosions can be reliably eliminated and the danger of corrosion avoided.
  • the apparatus may be provided in such a way that a connection with the surrounding air exists between the throttle location and the conveying means by means of which environmental air can be introduced into the circuit as a replacement for the mixture taken from the above-ambient pressure portion of the circuit.

  • the web is led through a blowing device 15' in which heated sterile air from a line 18 is blown on both sides of the web at high speed through slotted pipes 16.
  • the sterilising liquid still adhering to the web 15 is in this way atomised or volatilised into the chamber atmosphere.
  • the web After passing a direction changing roll 19, the web is, with the aid of the forming agents 20, 21 and 22, formed into a flexible tube which is welded together along the sides of the web to form a closed tube.
  • Air for welding is aspired from the surroundings with the aid of a blower 24, is heated with the aid of a heating spiral 25 and after passing a steriliser 26 is blown into a gap between the two overlapping longitudinal edges with the aid of a hood 2 7.
  • the plastics material located on the inside of the tube 23 is heated and contact rolls 28 effect hermetic welding with formation of a longitudinal seam.
  • a filling tube 29 protrudes into the interior-of the packaging tube and-with its aid the tube 23 is filled approximately to a level 30 with the sterile liquid to be packaged, e.g., pasteurized milk.
  • the sterile liquid to be packaged e.g., pasteurized milk.
  • the partly filled tube is subdivided into individual filled packages.
  • tetrahedral packages 32 are formed in known manner.
  • the interior of the sterile chamber is subjected to a preliminary sterilisation, for example by spraying a chemically active sterilising liquid combined with the feeding in of heated'air through the line 18.
  • the interior of the chamber 14 forms the component of a circuit in which the mixture of chamber air and sterilising agent vapor forming the chamber atmosphere is circulated with the aid of a conveying means such as a fan 33.
  • a conveying means such as a fan 33.
  • the bottom 34 of the chamber 14 is dish-shaped and at the lowest point a discharge take-off line 35 branches off and leads to a liquid separator 36. Separated liquid can be discharged periodically by means of a tap 37.
  • the mixture freed from liquid droplets enters the fan 33 through a line 38 and subsequently passes through a line- 39 into a filter 40, in whose inlet chamber 41 an electrically heated spiral heater 42 is located. From the filter 40, the conveyed medium returns to the chamber 14 via the line 18, namely into the blowing device 16.
  • a throttle means 43 is located in the line 38 to generate a small above-ambient pressure of, for example, S-mm water head in the chamber 14 while the fan 33 is running.
  • a means for limiting the concentration of the chemical sterilizing agent in the atmosphere filling the sterile chamber includes a line 44 which connects into the line 38 between the throttle means 43 and the fan 33 and through it fresh air from the surroundings can enter the described circuit.
  • a float-type fl'ow meter air from the surroundings enters the circuit through the line 44 to replace the mixture discharged from the circuit.
  • the temperature of the mixture fed in through the line 18 is suitably 120C.
  • a ratio of circulated mixture to introduced replacement air of about 2 2 I has been found to be suitable.
  • the meansfor limiting the concentration of sterilizing agent in the atmosphere filling the chamber includes a second chamber 52 which surrounds the tube 23 and follows on the annular gap 51 and from it the line 54 leading to the separator 53 branches off.
  • the bottom 55 of the second chamber forms a further annular gap 56 together with the flexible tube wall, through which the replacement air taken from the surroundings can enter the circuit'The air entering by the gap 56 prevents any mixtures of air and sterilising agent from leaking outside.
  • this circuit uses a conveying means in the form of a fan 57 and a filter means 58 with heating coil 59 from which the sterile mixture of air and sterilising agent vapor enters the blowing device 15, 16 via a line 60.
