      Contifeed preform feed system

      • Thanks to hygienic design optimal for the Contipure AseptBloc
      • Variants adjustable depending on the installation position

      Prejet preform rotary rinser

      Compact one-starwheel concept at ground level

      Method of operation:

      • Immersion of the rinser lances in the preforms
      • Blowing out of the particles with pre-filtered and ionised sterile air
      • At the same time as the particles are blown out: Extraction of the mix of air and dirt

      Infrared oven

      Servo-controlled oven of the Contiform standard series with efficient and pre-filtered preform air cooling system

      Option: Tool-free quick-change of the protective plates of the oven heating mandrels

      Optimised in terms of energy:

      • Smaller distances between heaters and longer infrared radiators
      • Use of parabolic mirrors

      Contipure D preform sterilisation module

      • The module is between infrared oven and aseptic blowing module.
      • Via nozzles, a targeted and directed feed of gaseous hydrogen peroxide (H2O2).
      • This provides an overflow and thus results in simultaneous internal and external preform sterilisation.

      Aseptic blowing module

      • The preforms are transferred to the aseptic blowing module after sterilisation.
      • The blowing process takes place within a sterile isolator which is protected from its environment by means of a liquid seal system.
      • The stretching rod never leaves the sterile zone during the entire blowing process.
      • The blowing process is carried out with pre-filtered sterile air.

      Central ventilation technology

      Cap sorting and inspection

      CapAsept D cap sterilisation module

      • Cap blower using ionised air right in front of the unit
      • Sterilisation by gaseous H2O2
      • No back-up pressure acting on the caps – no deformation
      • Clocked feed of the caps on demand: No bottle – no cap

      Aseptic capper

      • Every capping head has its own separate servo drive.
      • A transfer tunnel separates the sterile area from the outside area.
      • The proper technique for every cap – overcaps with round bottle possible!

      Valve manifold

      Media module

      Benefits to you

      Triple protection

      The all-round treatment with gaseous H2O2 sterilises the entire preform surface at once: Inside, outside and in the neck area.

      Fully-automatic change-over

      Handling parts change-over at the filler and the capper can be performed up to a defined output without any manual interference.

      Gentle preform treatment

      The sterilisation of the preforms hardly leaves any residues: This is because the surface enlarges by many times and the residues of the sterilisation medium are diluted accordingly.

      Pinpoint production

      Filling to the last drop: The system uses the remaining product quantity in order to calculate exactly how many more PET containers and caps are still to be sterilised.

      Proof of safety

      The concept of the Contipure AseptBloc has FDA certification and is already in practical use multiple times.

      Microbiological safety

      The system does not consume any water during operation. Therefore, there is no living space at all for microbiological organisms.

      High availability

      The entire block is in production for 168 hours non-stop. Depending on the product, it is cleaned and sterilised after 90 minutes or two and a half hours and can be used again. Intermediate cleaning after manual interventions also only takes 30 minutes.
