What it does
DSI applies ENOS prewash vision inspection at the decapper end of the returned-bottle line. Its job is not chemical sniffing; it is a safety screen that removes the bottles most likely to create mechanical trouble or carry visible contamination forward — capped or crowned containers, bottles with residual liquid, foreign objects, excess dirt, color anomalies, tilted or collapsed containers, or other defects that should be rejected before decapping.
Why before the decapper
Placed at the decapper infeed, DSI removes unsafe bottles before they reach the decapping machine, the prewash, the industrial washer or later Multi-Barrier detection stages. Because returned bottles arrive close together at this point rather than evenly spaced, it works as a fast safety screen rather than a full, evenly-spaced line inspection. Operators work from a touchscreen, with network access available for an optional remote-management service that provides online support over an internet connection.
What it checks
- Capped or crowned bottles — a sealed bottle traps a pressure difference that visibly collapses it, and DSI rejects it on that shape before the decapper.
- Residual liquid level and residual-liquid or bottle color.
- Foreign objects and extra-dirty returned bottles.
- Bottle perpendicularity — tilted or leaning containers.
- Label presence and label integrity.
- Foam and other conditions visible at the prewash stage.
