Definitions

  • the present invention relates to the technique of packaging and is concerned with a method for the cleaning and sterilizing of filler pipes in packing machines of the type which form a packing tube around a filler pipe and where the packing tube, partly filled with filling material, is divided up into filled and closed packages by means of clamping and sealing jaws arranged underneath the mouth of the filler pipe.
  • the method proposed by the invention should be regarded, however, as constituting a combination of cleaning and then sterilizing the inside and the outside of the filler pipe, or of dismantling and separating the filler pipe for manual washing or cleaning and then sterilizing the filler pipe in its production posi tion by making use of the packing tube as a container.
  • the invention also relates to a device which is intended to be used in the realization of the method, a filler pipe being provided with a level-controlling element arranged at its lower part, and being surrounded by a packing tube which, belowthe mouth of the filler pipe, is divided up by means of clamping and sealing jaws provided for this purpose.
  • the device is characterized so that the upper part of the filler pipe, during the cleaning and sterilizing operations, communicates either with a supply line for a cleaning agent or with a supply line for a sterilizing agent in gas or vapour form, the upper part of the filler pipe being adapted to be connected to a circulation and return line for the cleaning agent supplied via the supply line, and that an element for directing the gaseous or vaporous agent supplied to the filler pipe is arranged underneath the mouth of the lower part of the filler pipe.
  • the directing element arranged underneath the lower part of the filler pipe for the gaseous or vaporous agent is formed of a substantially hemispherical body, so that the filler pipe ends in the concave hollow of the body.
  • H0. 1 shows mainly supply, discharge and circulation lines to a filler pipe arranged for a cleaning operation
  • the lower part 5 of the filler pipe is adapted so that it can be detached from the upper part 4 of the filler pipe, as by a bayonet coupling 6 or some other connecting element.
  • a hemispherical body 8 Around the mouth 7 of part 5 of the filler pipe is arranged a hemispherical body 8 so that the filler pipe ends in the concave hollow of the body.
  • a distance above the mouth 7 of the filler pipe a level-controlling element 9 is provided.
  • the level-controlling element 9 is responsive to the level of the filling material present inside the tube, and controls the supply flow of the filling material.
  • the upper end 4 of the filler pipe communicates selectively with a supply line 10 for a cleaning and sterilizing agent, called hereinafter a detergent.
  • the filling material may also be supplied to the filler pipe through line 10 during production.
  • the upper part 4 of the filler pipe also communicates with a supply line 11 for a gaseous or vaporous sterilizing agent.
  • the lower part 5 of the filler pipe may be dismantled and a circulation line 12 connected to the bottom of the upper part 4 of the filler pipe as shown in FIG. 1.
  • the circulation line 12 has aflexible part 13 which can be connected-to the lower end of upper part 4 of the filler pipe (see FIG. 1).
  • An outlet line 14 is provided for the discharge for the detergent and for passing filling material to the filler pipe of another filling machine which may be coupled to the same system. It is also possible of course, if desired, to pass the gaseous or vaporous sterilizing agent through the outlet pipe 14 to the next packing machine for sterilizing the same.
  • a multi-way valve 15 is provided for controlling the various flows from the inlet line 10 through the circulation line 12 and out through the outlet line 14 during the cleaning sequence and the filling sequence.
  • the method for the cleaning and sterilizing of the filler pipe operates in the following manner.
  • the sterile filling material such as milk
  • the sterile filling material is supplied during production through the inlet line 10 and is passed through the filler pipe 4, 5 and via its mouth 7 to the inside of the packing tube 1 (see FIG. 2) where the amount of filling material attains a certain level determined by control element 9.
  • the inlet line 11 for the gaseous or vaporous sterilizing agent is shut off and the circulation line 12 for the detergent is of course removed.
  • the outlet line 14 is open so that the filling material can also pass to the next machine.
  • the outlet line 14 shall also be open for the last machine in series so that any residue of sterile filling material may be returned to the sterilizer.
  • the outlet line 14 of the last machine in the series will have to be closed so as to prevent the filling material from coming into contact with parts of the installation that cannot be sterilized.
  • the packing tube 1 is cut off immediately underneath the lowest of the forming rings 2 as seen in FIG. 1.
  • the lower part 5 of the filler pipe which includes the jet-directing element 8 and the levelcontrolling element 9, is detached for manual washing.
  • the flexible lower part 13 of the circulation line 12 is connected to the lower end of the upper part 4 of the filler pipe by means of coupling device 6, as shown in FIG. 1..
  • a cleaning or washing agent 7 is introduced then through the inlet line 10 to the upper part 4 ofthe filler pipe, the detergent being allowed to circulate through the connected circulation line 12.
  • the detergent is discharged from the system. or taken to some other packing machine. which is ready for a cleaning operation, through the outlet line 14.
  • the detergent may comprise a 2% caustic soda (NaOH) solution. an acid or some other suitable detergent.
  • a possible rinsing of the system may take place by means of hot water or the like. which is made to circulate in the same manner as the detergent.
  • the cleaning operation is carried out, as mentioned above, after production has been completed or after prolonged'stoppages.
  • a further washing operation may be carried out before the packing machine is put into operation again, for example on the morning of the following day.
  • at least one sterilization is carried out after the system has been cleaned of residues of filling material, residues of dirt and the like.
  • the circulation line 12 is dismantled from the lower end of upper part 4 of the filler pipe and its lower part 5, which has been washed manually, is attached thereto. Subsequently the packing tube 1 is drawn down to the sealing jaws 3 and a longitudinal joint is obtained, whereupon the packing tube is divided by clamping it between sealing jaws 3.
  • a sterilizing agent such as superheated steam or hot water
  • a sterilizing agent such as superheated steam or hot water
  • one position of the multi-way valve 15 shuts off the communication between inlet line 10 and filler pipe 4, 5 and another position shuts off the circulation line 12, which latter line does not have to be sterile and accordingly does not have to be subjected to any sterilization.
  • a gaseous orvaporous sterilizing agent is introduced into the filler pipe 4, 5 which discharges into the jet-directing element 8.
  • the sterilizing agent in gas or vapour form then sterilizes the inside of the filler pipe and also the outside of the same.
  • the sterilizing agent is in fact urged .to flow along the outside of the filler pipe, whereby at least the lower part of the latter and elements arranged thereon such as level-controlling elements and the like are sterilized.
  • the jet-directing element 8 does not permit the gaseous or vaporous agent to flow directly towards the packing tube at least at that part of the tube which is situated in the areanearest to the mouth 7 of the filler pipe 4, 5.
  • the gaseousor vaporous agent supplied through the inlet line 11 is guided in this case only through and around the filler pipe 4, 5 since the communication through the multi-wayvalve 15 is shut off, and is vented through the upper open portion of the packing tube prior to being shaped by rings 2.
