GEA launches new filling technology for ESL beverages

Compact simplicity and efficiency

Sensitive, milk-based ESL beverages need special requirements to preserve their shelf-life and organoleptic properties. As such, container decontamination is an essential part of the process to ensure an effective and reliable extended shelf-life in cold chain distribution.

The GEA Whitebloc Aero’s design is optimized for the treatment time required in ESL applications; this allows bottle decontamination with dry H₂O₂ and subsequent activation with warm air to be performed on a single carousel which keeps the layout as compact as possible.

The decontamination, filling and capping processes are performed in a simple hygienic cabin with a top-down laminar flow of sterile air with a slight overpressure to maintain a clean and protected environment.

Speed and Flexibility

The ESL market frequently requires producers to run small batches and fill a variety of products on the same machine. The GEA Whitebloc Aero offers the typical production rate of fresh and ESL applications, using both PET and HDPE containers with plastic caps or aluminum foil closures and using neck or base handling. The machine can be supplied in a standalone configuration or, for PET bottles, combined with a stretch blow molding machine.

The GEA Whitebloc Aero can achieve a wide range of decontamination targets depending on the required level of product sensitivity and shelf-life for both high and low-acid products. Equipment cleaning is fast, cost-effective and flexible thanks to the possibility to choose between the integration of customers’ existing fluid cleaning system or a dedicated cleaning process skid unit embedded with the GEA Whitebloc Aero.

A built-in product recovery system eliminates product waste during the start-up cycle, at the end of production and during changeovers. Filling valves can be equipped with a load cell (weight filling) or flow meter (volumetric filling) to meet the various requirements of the liquid dairy product market.

Environmentally sustainable

No water is used in the process so producers can be confident that production is not wasting scarce natural resources. Both bottles and closures are treated using the same chemical for maximum convenience and consistency.
