BOCHUM, GERMANY — GEA Procomac has introduced aseptic blow fill (ABF) technology that maintains the sterility of the process, minimizes the use of chemicals, requires no bottle rinsing, enables a simpler and smaller layout, and reduces energy consumption, according to the company.
The ABF, a rotary aseptic blow molding machine, comes with an integrated aseptic filler and capper. It sterilizes the preform, not the formed bottle, with hydrogen peroxide at the exit from the oven, which reduces the quantity of sterilizing agent used because the preform is smaller and easier to shape. It then blows the preform with sterile air in a sterile environment and maintains the sterility throughout the filling and capping process.
Since the preform is made of thicker material, it is possible to increase the temperature of the treatment without risk of shrinkage.
All non-cleanable components are located outside of the sterile zone. Electrical components are located above the sterile zone while mechanical components and all components that require lubrication are located below the sterile zone. All surfaces in the sterile zone are accessible for cleaning.
