Bosch Packaging Technology RAN 3080 high-pressure cleaning system

The RAN 3080 high-pressure cleaning system combines the high-pressure process with an efficient transportation system, allowing for residue-free cleaning of up to 400 containers/min.

The machine consists of a rotary platform for cleaning and an identical rotary platform for drying. Following the infeed, the transportation system first grips the container by its closure caps. This enables cleaning of virtually the entire container surface, including the neck. The ring nozzles of the cleaning station operate with high pressure, washing the containers from top to bottom. Additional bottom nozzles provide for clean container bases. Pressurised air continuously flows across the closure caps. It stops moisture from getting to the closure rim and into the containers, thereby preventing product contamination.

The system features three individual washing stations, which enable the cleaning processes to be adapted to user requirements. Up to three different media can be used per cycle. Drying also takes place at three stations. Thanks to a strict separation of cleaning and drying areas, the machine prevents a recontamination of the containers after washing.

Depending on production requirements, the washing machine can be equipped with different containment devices: options range from containment housing for the protection against harmful and toxic substances to macrolon covers for non-toxic applications. An optional circulation system achieves savings by consistently re-using slightly contaminated cleaning media.
