GEA Whitebloc Filling System ESL

In a two-phase process the bottles first enter a first carrousel and are sprayed with a hydrogen peroxide (H2O2) solution. All critical points are controlled automatically to ensure maximum decontamination efficacy.

After the ‘dosing’ phase, the ‘activating phase’ takes place in a second carrousel. Here, the bottles are flushed with hot sterile air that activates the H2O2, purges out peroxides and achieves a final peroxide concentration of less than 0.5 ppm. No water rinsing is required.

Clean Box: the key to ESL technology

The Clean Box is a physically isolated ultraclean environment. To prevent the bottles becoming contaminated after H2O2 treatment, the filler/capper zone is surrounded by a HEPA filter providing a sterile air flow with an ambient overpressure of 10 Pa.

The surfaces within the Clean Box are both accessible and easy to clean.

Benefits:

•    Effective and flexible, different decontamination targets – up to 5 log on A.brasiliensis and up to 3 log on B.atrophaeus – to meet the shelf-life requirements of a wide variety of products can be achieved
•    Available for a wide range of bottle formats, ranging from ’single serve’ 200 ml bottles to 1 US gallon format
•    Low maintenance: no moving parts or valves are installed on the two carrousels
•    Small footprint

Performance

Whitebloc ESL ensures a decontamination target up to 5 log reduction on A.brasiliensis and up to 3 log reduction on B.atrophaeus upon completion of the ESL treatments. Whitebloc ESL is optimized for low to medium speed applications.
