The concept
The preforms are sterilized as soon as they leave the oven, where they are heated to optimize their thermal profiling and to minimize energy consumption and the use of the sterilizing agent. The internal and external surfaces of the preforms are treated with vaporized hydrogen peroxide (VHP) using a robust, controlled and condensation-free process to minimize residue values and achieve a 6 log decontamination performance.
After the sterilization process, the preforms enter a pre-sterilized microbiological isolator – where the aseptic blowing wheel is located – and are blown with sterile air supplied through a filtered circuit that includes a dedicated VHP sterilization system.
The fresh-blown sterile bottles are transferred by the neck from the aseptic blower to the aseptic filling module without leaving the sterile zone. The aseptic filler is enclosed in the same microbiological isolator, in which sterility is maintained during production with an overpressure of class 100 sterile air. As well as the filler module, the capper module in the ABF 2.0 system is specifically designed for aseptic applications and completely enclosed within the microbiological isolator.
Benefit:
- Full automated sterilization of the blowing, filling and capping modules, resulting in an effective, repeatable and automated process, needing no operator intervention
- Low chemical and no water consumption during production
- Minimum H2O2 residuals in the container (<0.5 ppm)
- Limited downtime (3 hours cleaning and sterilization cycles) for product changeovers
- Microbiological validation according to specific protocols for sensitive beverage industry
- PoC approved, being based on ABF 1.2 FDA approved architecture
Aseptic blower
The GEA Aseptic Blow Molder is an integral part of the ABF 2.0 system. It is an aseptic blower that produces sterilized bottles by aseptically blowing preforms being previously sterilized with hydrogen peroxide vapor (VHP).
Specifically designed with aseptic functionality in mind, the GEA Aseptic Blow Molder is placed in the same sterile zone where the filling and capping processes are performed. It has been designed to be completely sterilizable.

Blow molder aseptic design
The environmental sterilization process is completely automated requiring no manual intervention from the operator, therefore greatly decreasing any risk of system recontamination.

Resource-efficient solution
The air recovery system in aseptic blower is one of our most resource-efficient solutions and carries the Add Better label.
The Add Better label relates to the air recovery system in GEA ABF 2.0 which reduces the amount of energy consumption for the compressed air needed for blowing process and cap sterilization up to 31% when compared to its predecessor model.
The air recovery system was released in 2024.
Performance
The versatile ABF 2.0 aseptic production system can process extremely sensitive, high and low acid, still or carbonated beverages, with or without particles. It can deliver a 6 log reduction for both cap and preform decontamination in a single sterilization phase and offers continuous aseptic production runs of 165 hours without stoppages or intermediate cleaning.
H2O2 technology for cap and foil sterilization
Similar to the preform sterilization system, the ABF 2.0 cap sterilization module – Sterilcap VHP R – also uses VHP at the correct concentration and temperature. The specially adapted design, including a rotary cap buffer that guarantees the necessary redundancy required by the blow-fill technology, ensures that all the cap surfaces are exposed, preventing any ‘shadow’ areas and avoiding the risk of cap deformation.
The cap sterilization module can be used to treat both sport and flat caps. Offering rapid changeovers without any mechanical intervention and without losing sterility, the ABF 2.0 solution offers maximum flexibility when treating aluminum foil closures with Sterilfoil VHP L technology.
