The transport system grips the containers at the closure, ensuring an effective cleaning of virtually the entire container surface. The RAN 3080 enables the elimination of process-related contamination, which could harm recipients’ and patients’ health. By combining the high-pressure process with an efficient transportation system, the system allows for a 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 containers by their closure caps. This enables cleaning of virtually the entire container surface, including the neck. The ring nozzles of the cleaning station, which operate with high pressure, subsequently wash the containers from top to bottom. Additional bottom nozzles provide for clean container bases. Pressurized 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 RAN 3080 features three individual washing stations, which enable the cleaning processes to be optimally adapted to different customer demands. Up to three different media can be used per cycle; apart from water, acids and alkaline solutions are applicable for heavy contamination. Drying also takes place at three stations with pressurized air from both ring and bottom nozzles, and ensures that no residual moisture sticks to the containers. Thanks to a strict separation of cleaning and drying area, the machine further prevents a re-contamination of the containers after washing.
